Whether those things that are of faith should be divided into certain articles?

Objection 1. It would seem that those things that are of faith should not be divided into certain articles. For all things contained in Holy Writ are matters of faith. But these, by reason of their multitude, cannot be reduced to a certain number. Therefore it seems superfluous to distinguish certain articles of faith.

Objection 2. Further, material differences can be multiplied indefinitely, and therefore art should take no notice of them. Now the formal aspect of the object of faith is one and indivisible, as stated above (Article 1), viz. the First Truth, so that matters of faith cannot be distinguished in respect of their formal object. Therefore no notice should be taken of a material division of matters of faith into articles.

Objection 3. Further, it has been said by some [Cf. William of Auxerre, Summa Aurea] that "an article is an indivisible truth concerning God, exacting [arctans] our belief." Now belief is a voluntary act, since, as Augustine says (Tract. xxvi in Joan.), "no man believes against his will." Therefore it seems that matters of faith should not be divided into articles.

On the contrary, Isidore says: "An article is a glimpse of Divine truth, tending thereto." Now we can only get a glimpse of Divine truth by way of analysis, since things which in God are one, are manifold in our intellect. Therefore matters of faith should be divided into articles.

I answer that, the word "article" is apparently derived from the Greek; for the Greek arthron [Cf. William of Auxerre, Summa Aurea] which the Latin renders "articulus," signifies a fitting together of distinct parts: wherefore the small parts of the body which fit together are called the articulations of the limbs. Likewise, in the Greek grammar, articles are parts of speech which are affixed to words to show their gender, number or case. Again in rhetoric, articles are parts that fit together in a sentence, for Tully says (Rhet. iv) that an article is composed of words each pronounced singly and separately, thus: "Your passion, your voice, your look, have struck terror into your foes."

Hence matters of Christian faith are said to contain distinct articles, in so far as they are divided into parts, and fit together. Now the object of faith is something unseen in connection with God, as stated above (Article 4). Consequently any matter that, for a special reason, is unseen, is a special article; whereas when several matters are known or not known, under the same aspect, we are not to distinguish various articles. Thus one encounters one difficulty in seeing that God suffered, and another in seeing that He rose again from the dead, wherefore the article of the Resurrection is distinct from the article of the Passion. But that He suffered, died and was buried, present the same difficulty, so that if one be accepted, it is not difficult to accept the others; wherefore all these belong to one article.

Reply to Objection 1. Some things are proposed to our belief are in themselves of faith, while others are of faith, not in themselves but only in relation to others: even as in sciences certain propositions are put forward on their own account, while others are put forward in order to manifest others. Now, since the chief object of faith consists in those things which we hope to see, according to Hebrews 11:2: "Faith is the substance of things to be hoped for," it follows that those things are in themselves of faith, which order us directly to eternal life. Such are the Trinity of Persons in Almighty God [The Leonine Edition reads: The Three Persons, the omnipotence of God, etc.], the mystery of Christ's Incarnation, and the like: and these are distinct articles of faith. On the other hand certain things in Holy Writ are proposed to our belief, not chiefly on their own account, but for the manifestation of those mentioned above: for instance, that Abraham had two sons, that a dead man rose again at the touch of Eliseus' bones, and the like, which are related in Holy Writ for the purpose of manifesting the Divine mystery or the Incarnation of Christ: and such things should not form distinct articles.

Reply to Objection 2. The formal aspect of the object of faith can be taken in two ways: first, on the part of the thing believed, and thus there is one formal aspect of all matters of faith, viz. the First Truth: and from this point of view there is no distinction of articles. Secondly, the formal aspect of matters of faith, can be considered from our point of view; and thus the formal aspect of a matter of faith is that it is something unseen; and from this point of view there are various distinct articles of faith, as we saw above.

Reply to Objection 3. This definition of an article is taken from an etymology of the word as derived from the Latin, rather than in accordance with its real meaning, as derived from the Greek: hence it does not carry much weight. Yet even then it could be said that although faith is exacted of no man by a necessity of coercion, since belief is a voluntary act, yet it is exacted of him by a necessity of end, since "he that cometh to God must believe that He is," and "without faith it is impossible to please God," as the Apostle declares (Hebrews 11:6).


Whether the articles of faith have increased in course of time?

Objection 1. It would seem that the articles of faith have not increased in course of time. Because, as the Apostle says (Hebrews 11:1), "faith is the substance of things to be hoped for." Now the same things are to be hoped for at all times. Therefore, at all times, the same things are to be believed.

Objection 2. Further, development has taken place, in sciences devised by man, on account of the lack of knowledge in those who discovered them, as the Philosopher observes (Metaph. ii). Now the doctrine of faith was not devised by man, but was delivered to us by God, as stated in Ephesians 2:8: "It is the gift of God." Since then there can be no lack of knowledge in God, it seems that knowledge of matters of faith was perfect from the beginning and did not increase as time went on.

Objection 3. Further, the operation of grace proceeds in orderly fashion no less than the operation of nature. Now nature always makes a beginning with perfect things, as Boethius states (De Consol. iii). Therefore it seems that the operation of grace also began with perfect things, so that those who were the first to deliver the faith, knew it most perfectly.

Objection 4. Further, just as the faith of Christ was delivered to us through the apostles, so too, in the Old Testament, the knowledge of faith was delivered by the early fathers to those who came later, according to Deuteronomy 32:7: "Ask thy father, and he will declare to thee." Now the apostles were most fully instructed about the mysteries, for "they received them more fully than others, even as they received them earlier," as a gloss says on Romans 8:23: "Ourselves also who have the first fruits of the Spirit." Therefore it seems that knowledge of matters of faith has not increased as time went on.

On the contrary, Gregory says (Hom. xvi in Ezech.) that "the knowledge of the holy fathers increased as time went on . . . and the nearer they were to Our Savior's coming, the more fully did they received the mysteries of salvation."

I answer that, The articles of faith stand in the same relation to the doctrine of faith, as self-evident principles to a teaching based on natural reason. Among these principles there is a certain order, so that some are contained implicitly in others; thus all principles are reduced, as to their first principle, to this one: "The same thing cannot be affirmed and denied at the same time," as the Philosopher states (Metaph. iv, text. 9). On like manner all the articles are contained implicitly in certain primary matters of faith, such as God's existence, and His providence over the salvation of man, according to Hebrews 11: "He that cometh to God, must believe that He is, and is a rewarder to them that seek Him." For the existence of God includes all that we believe to exist in God eternally, and in these our happiness consists; while belief in His providence includes all those things which God dispenses in time, for man's salvation, and which are the way to that happiness: and in this way, again, some of those articles which follow from these are contained in others: thus faith in the Redemption of mankind includes belief in the Incarnation of Christ, His Passion and so forth.

Accordingly we must conclude that, as regards the substance of the articles of faith, they have not received any increase as time went on: since whatever those who lived later have believed, was contained, albeit implicitly, in the faith of those Fathers who preceded them. But there was an increase in the number of articles believed explicitly, since to those who lived in later times some were known explicitly which were not known explicitly by those who lived before them. Hence the Lord said to Moses (Exodus 6:2-3): "I am the God of Abraham, the God of Isaac, the God of Jacob [Vulgate: 'I am the Lord that appeared to Abraham, to Isaac, and to Jacob'] . . . and My name Adonai I did not show them": David also said (Psalm 118:100): "I have had understanding above ancients": and the Apostle says (Ephesians 3:5) that the mystery of Christ, "in other generations was not known, as it is now revealed to His holy apostles and prophets."

Reply to Objection 1. Among men the same things were always to be hoped for from Christ. But as they did not acquire this hope save through Christ, the further they were removed from Christ in point of time, the further they were from obtaining what they hoped for. Hence the Apostle says (Hebrews 11:13): "All these died according to faith, not having received the promises, but beholding them afar off." Now the further off a thing is the less distinctly is it seen; wherefore those who were nigh to Christ's advent had a more distinct knowledge of the good things to be hoped for.

Reply to Objection 2. Progress in knowledge occurs in two ways. First, on the part of the teacher, be he one or many, who makes progress in knowledge as time goes on: and this is the kind of progress that takes place in sciences devised by man. Secondly, on the part of the learner; thus the master, who has perfect knowledge of the art, does not deliver it all at once to his disciple from the very outset, for he would not be able to take it all in, but he condescends to the disciple's capacity and instructs him little by little. It is in this way that men made progress in the knowledge of faith as time went on. Hence the Apostle (Galatians 3:24) compares the state of the Old Testament to childhood.

Reply to Objection 3. Two causes are requisite before actual generation can take place, an agent, namely, and matter. On the order of the active cause, the more perfect is naturally first; and in this way nature makes a beginning with perfect things, since the imperfect is not brought to perfection, except by something perfect already in existence. On the other hand, in the order of the material cause, the imperfect comes first, and in this way nature proceeds from the imperfect to the perfect. Now in the manifestation of faith, God is the active cause, having perfect knowledge from all eternity; while man is likened to matter in receiving the influx of God's action. Hence, among men, the knowledge of faith had to proceed from imperfection to perfection; and, although some men have been after the manner of active causes, through being doctors of faith, nevertheless the manifestation of the Spirit is given to such men for the common good, according to 1 Corinthians 12:7; so that the knowledge of faith was imparted to the Fathers who were instructors in the faith, so far as was necessary at the time for the instruction of the people, either openly or in figures.

Reply to Objection 4. The ultimate consummation of grace was effected by Christ, wherefore the time of His coming is called the "time of fulness [Vulgate: 'fulness of time']" (Galatians 4:4). Hence those who were nearest to Christ, wherefore before, like John the Baptist, or after, like the apostles, had a fuller knowledge of the mysteries of faith; for even with regard to man's state we find that the perfection of manhood comes in youth, and that a man's state is all the more perfect, whether before or after, the nearer it is to the time of his youth.


Whether the articles of faith are suitably formulated?

Objection 1. It would seem that the articles of faith are unsuitably formulated. For those things, which can be known by demonstration, do not belong to faith as to an object of belief for all, as stated above (Article 5). Now it can be known by demonstration that there is one God; hence the Philosopher proves this (Metaph. xii, text. 52) and many other philosophers demonstrated the same truth. Therefore that "there is one God" should not be set down as an article of faith.

Objection 2. Further, just as it is necessary to faith that we should believe God to be almighty, so is it too that we should believe Him to be "all-knowing" and "provident for all," about both of which points some have erred. Therefore, among the articles of faith, mention should have been made of God's wisdom and providence, even as of His omnipotence.

Objection 3. Further, to know the Father is the same things as to know the Son, according to John 14:9: "He that seeth Me, seeth the Father also." Therefore there ought to be but one article about the Father and Son, and, for the same reason, about the Holy Ghost.

Objection 4. Further, the Person of the Father is no less than the Person of the Son, and of the Holy Ghost. Now there are several articles about the Person of the Holy Ghost, and likewise about the Person of the Son. Therefore there should be several articles about the Person of the Father.

Objection 5. Further, just as certain things are said by appropriation, of the Person of the Father and of the Person of the Holy Ghost, so too is something appropriated to the Person of the Son, in respect of His Godhead. Now, among the articles of faith, a place is given to a work appropriated to the Father, viz. the creation, and likewise, a work appropriated to the Holy Ghost, viz. that "He spoke by the prophets." Therefore the articles of faith should contain some work appropriated to the Son in respect of His Godhead.

Objection 6. Further, the sacrament of the Eucharist presents a special difficulty over and above the other articles. Therefore it should have been mentioned in a special article: and consequently it seems that there is not a sufficient number of articles.

On the contrary stands the authority of the Church who formulates the articles thus.

I answer that, As stated above (Articles 4 and 6), to faith those things in themselves belong, the sight of which we shall enjoy in eternal life, and by which we are brought to eternal life. Now two things are proposed to us to be seen in eternal life: viz. the secret of the Godhead, to see which is to possess happiness; and the mystery of Christ's Incarnation, "by Whom we have access" to the glory of the sons of God, according to Romans 5:2. Hence it is written (John 17:3): "This is eternal life: that they may know Thee, the . . . true God, and Jesus Christ Whom Thou hast sent." Wherefore the first distinction in matters of faith is that some concern the majesty of the Godhead, while others pertain to the mystery of Christ's human nature, which is the "mystery of godliness" (1 Timothy 3:16).

Now with regard to the majesty of the Godhead, three things are proposed to our belief: first, the unity of the Godhead, to which the first article refers; secondly, the trinity of the Persons, to which three articles refer, corresponding to the three Persons; and thirdly, the works proper to the Godhead, the first of which refers to the order of nature, in relation to which the article about the creation is proposed to us; the second refers to the order of grace, in relation to which all matters concerning the sanctification of man are included in one article; while the third refers to the order of glory, and in relation to this another article is proposed to us concerning the resurrection of the dead and life everlasting. Thus there are seven articles referring to the Godhead.

In like manner, with regard to Christ's human nature, there are seven articles, the first of which refers to Christ's incarnation or conception; the second, to His virginal birth; the third, to His Passion, death and burial; the fourth, to His descent into hell; the fifth, to His resurrection; the sixth, to His ascension; the seventh, to His coming for the judgment, so that in all there are fourteen articles.

Some, however, distinguish twelve articles, six pertaining to the Godhead, and six to the humanity. For they include in one article the three about the three Persons; because we have one knowledge of the three Persons: while they divide the article referring to the work of glorification into two, viz. the resurrection of the body, and the glory of the soul. Likewise they unite the conception and nativity into one article.

Reply to Objection 1. By faith we hold many truths about God, which the philosophers were unable to discover by natural reason, for instance His providence and omnipotence, and that He alone is to be worshiped, all of which are contained in the one article of the unity of God.

Reply to Objection 2. The very name of the Godhead implies a kind of watching over things, as stated in I:13:8. Now in beings having an intellect, power does not work save by the will and knowledge. Hence God's omnipotence includes, in a way, universal knowledge and providence. For He would not be able to do all He wills in things here below, unless He knew them, and exercised His providence over them.

Reply to Objection 3. We have but one knowledge of the Father, Son, and Holy Ghost, as to the unity of the Essence, to which the first article refers: but, as to the distinction of the Persons, which is by the relations of origin, knowledge of the Father does indeed, in a way, include knowledge of the Son, for He would not be Father, had He not a Son; the bond whereof being the Holy Ghost. From this point of view, there was a sufficient motive for those who referred one article to the three Persons. Since, however, with regard to each Person, certain points have to be observed, about which some happen to fall into error, looking at it in this way, we may distinguish three articles about the three Persons. For Arius believed in the omnipotence and eternity of the Father, but did not believe the Son to be co-equal and consubstantial with the Father; hence the need for an article about the Person of the Son in order to settle this point. On like manner it was necessary to appoint a third article about the Person of the Holy Ghost, against Macedonius. On the same way Christ's conception and birth, just as the resurrection and life everlasting, can from one point of view be united together in one article, in so far as they are ordained to one end; while, from another point of view, they can be distinct articles, in as much as each one separately presents a special difficulty.

Reply to Objection 4. It belongs to the Son and Holy Ghost to be sent to sanctify the creature; and about this several things have to be believed. Hence it is that there are more articles about the Persons of the Son and Holy Ghost than about the Person of the Father, Who is never sent, as we stated in I:43:4.

Reply to Objection 5. The sanctification of a creature by grace, and its consummation by glory, is also effected by the gift of charity, which is appropriated to the Holy Ghost, and by the gift of wisdom, which is appropriated to the Son: so that each work belongs by appropriation, but under different aspects, both to the Son and to the Holy Ghost.

Reply to Objection 6. Two things may be considered in the sacrament of the Eucharist. One is the fact that it is a sacrament, and in this respect it is like the other effects of sanctifying grace. The other is that Christ's body is miraculously contained therein and thus it is included under God's omnipotence, like all other miracles which are ascribed to God's almighty power.


Whether it is suitable for the articles of faith to be embodied in a symbol?

Objection 1. It would seem that it is unsuitable for the articles of faith to be embodied in a symbol. Because Holy Writ is the rule of faith, to which no addition or subtraction can lawfully be made, since it is written (Deuteronomy 4:2): "You shall not add to the word that I speak to you, neither shall you take away from it." Therefore it was unlawful to make a symbol as a rule of faith, after the Holy Writ had once been published.

Objection 2. Further, according to the Apostle (Ephesians 4:5) there is but "one faith." Now the symbol is a profession of faith. Therefore it is not fitting that there should be more than one symbol.

Objection 3. Further, the confession of faith, which is contained in the symbol, concerns all the faithful. Now the faithful are not all competent to believe in God, but only those who have living faith. Therefore it is unfitting for the symbol of faith to be expressed in the words: "I believe in one God."

Objection 4. Further, the descent into hell is one of the articles of faith, as stated above (Article 8). But the descent into hell is not mentioned in the symbol of the Fathers. Therefore the latter is expressed inadequately.

Objection 5. Further, Augustine (Tract. xxix in Joan.) expounding the passage, "You believe in God, believe also in Me" (John 14:1) says: "We believe Peter or Paul, but we speak only of believing 'in' God." Since then the Catholic Church is merely a created being, it seems unfitting to say: "In the One, Holy, Catholic and Apostolic Church."

Objection 6. Further, a symbol is drawn up that it may be a rule of faith. Now a rule of faith ought to be proposed to all, and that publicly. Therefore every symbol, besides the symbol of the Fathers, should be sung at Mass. Therefore it seems unfitting to publish the articles of faith in a symbol.

On the contrary, The universal Church cannot err, since she is governed by the Holy Ghost, Who is the Spirit of truth: for such was Our Lord's promise to His disciples (John 16:13): "When He, the Spirit of truth, is come, He will teach you all truth." Now the symbol is published by the authority of the universal Church. Therefore it contains nothing defective.

I answer that, As the Apostle says (Hebrews 11:6), "he that cometh to God, must believe that He is." Now a man cannot believe, unless the truth be proposed to him that he may believe it. Hence the need for the truth of faith to be collected together, so that it might the more easily be proposed to all, lest anyone might stray from the truth through ignorance of the faith. It is from its being a collection of maxims of faith that the symbol [The Greek symballein] takes its name.

Reply to Objection 1. The truth of faith is contained in Holy Writ, diffusely, under various modes of expression, and sometimes obscurely, so that, in order to gather the truth of faith from Holy Writ, one needs long study and practice, which are unattainable by all those who require to know the truth of faith, many of whom have no time for study, being busy with other affairs. And so it was necessary to gather together a clear summary from the sayings of Holy Writ, to be proposed to the belief of all. This indeed was no addition to Holy Writ, but something taken from it.

Reply to Objection 2. The same doctrine of faith is taught in all the symbols. Nevertheless, the people need more careful instruction about the truth of faith, when errors arise, lest the faith of simple-minded persons be corrupted by heretics. It was this that gave rise to the necessity of formulating several symbols, which nowise differ from one another, save that on account of the obstinacy of heretics, one contains more explicitly what another contains implicitly.

Reply to Objection 3. The confession of faith is drawn up in a symbol in the person, as it were, of the whole Church, which is united together by faith. Now the faith of the Church is living faith; since such is the faith to be found in all those who are of the Church not only outwardly but also by merit. Hence the confession of faith is expressed in a symbol, in a manner that is in keeping with living faith, so that even if some of the faithful lack living faith, they should endeavor to acquire it.

Reply to Objection 4. No error about the descent into hell had arisen among heretics, so that there was no need to be more explicit on that point. For this reason it is not repeated in the symbol of the Fathers, but is supposed as already settled in the symbol of the Apostles. For a subsequent symbol does not cancel a preceding one; rather does it expound it, as stated above (Reply to Objection 2).

Reply to Objection 5. If we say: "'In' the holy Catholic Church," this must be taken as verified in so far as our faith is directed to the Holy Ghost, Who sanctifies the Church; so that the sense is: "I believe in the Holy Ghost sanctifying the Church." But it is better and more in keeping with the common use, to omit the 'in,' and say simply, "the holy Catholic Church," as Pope Leo [Rufinus, Comm. in Sym. Apost.] observes.

Reply to Objection 6. Since the symbol of the Fathers is an explanation of the symbol of the Apostles, and was drawn up after the faith was already spread abroad, and when the Church was already at peace, it is sung publicly in the Mass. On the other hand the symbol of the Apostles, which was drawn up at the time of persecution, before the faith was made public, is said secretly at Prime and Compline, as though it were against the darkness of past and future errors.


Whether it belongs to the Sovereign Pontiff to draw up a symbol of faith?

Objection 1. It would seem that it does not belong to the Sovereign Pontiff to draw up a symbol of faith. For a new edition of the symbol becomes necessary in order to explain the articles of faith, as stated above (Article 9). Now, in the Old Testament, the articles of faith were more and more explained as time went on, by reason of the truth of faith becoming clearer through greater nearness to Christ, as stated above (Article 7). Since then this reason ceased with the advent of the New Law, there is no need for the articles of faith to be more and more explicit. Therefore it does not seem to belong to the authority of the Sovereign Pontiff to draw up a new edition of the symbol.

Objection 2. Further, no man has the power to do what is forbidden under pain of anathema by the universal Church. Now it was forbidden under pain of anathema by the universal Church, to make a new edition of the symbol. For it is stated in the acts of the first council of Ephesus (P. ii, Act. 6) that "after the symbol of the Nicene council had been read through, the holy synod decreed that it was unlawful to utter, write or draw up any other creed, than that which was defined by the Fathers assembled at Nicaea together with the Holy Ghost," and this under pain of anathema. St. Thomas wrote 'first' (expunged by Nicolai) to distinguish it from the other council, A.D. 451, known as the "Latrocinium" and condemned by the Pope. The same was repeated in the acts of the council of Chalcedon (P. ii, Act. 5). Therefore it seems that the Sovereign Pontiff has no authority to publish a new edition of the symbol.

Objection 3. Further, Athanasius was not the Sovereign Pontiff, but patriarch of Alexandria, and yet he published a symbol which is sung in the Church. Therefore it does not seem to belong to the Sovereign Pontiff any more than to other bishops, to publish a new edition of the symbol.

On the contrary, The symbol was drawn us by a general council. Now such a council cannot be convoked otherwise than by the authority of the Sovereign Pontiff, as stated in the Decretals [Dist. xvii, Can. 4,5. Therefore it belongs to the authority of the Sovereign Pontiff to draw up a symbol.

I answer that, As stated above (Objection 1), a new edition of the symbol becomes necessary in order to set aside the errors that may arise. Consequently to publish a new edition of the symbol belongs to that authority which is empowered to decide matters of faith finally, so that they may be held by all with unshaken faith. Now this belongs to the authority of the Sovereign Pontiff, "to whom the more important and more difficult questions that arise in the Church are referred," as stated in the Decretals [Dist. xvii, Can. 5. Hence our Lord said to Peter whom he made Sovereign Pontiff (Luke 22:32): "I have prayed for thee," Peter, "that thy faith fail not, and thou, being once converted, confirm thy brethren." The reason of this is that there should be but one faith of the whole Church, according to 1 Corinthians 1:10: "That you all speak the same thing, and that there be no schisms among you": and this could not be secured unless any question of faith that may arise be decided by him who presides over the whole Church, so that the whole Church may hold firmly to his decision. Consequently it belongs to the sole authority of the Sovereign Pontiff to publish a new edition of the symbol, as do all other matters which concern the whole Church, such as to convoke a general council and so forth.

Reply to Objection 1. The truth of faith is sufficiently explicit in the teaching of Christ and the apostles. But since, according to 2 Peter 3:16, some men are so evil-minded as to pervert the apostolic teaching and other doctrines and Scriptures to their own destruction, it was necessary as time went on to express the faith more explicitly against the errors which arose.

Reply to Objection 2. This prohibition and sentence of the council was intended for private individuals, who have no business to decide matters of faith: for this decision of the general council did not take away from a subsequent council the power of drawing up a new edition of the symbol, containing not indeed a new faith, but the same faith with greater explicitness. For every council has taken into account that a subsequent council would expound matters more fully than the preceding council, if this became necessary through some heresy arising. Consequently this belongs to the Sovereign Pontiff, by whose authority the council is convoked, and its decision confirmed.

Reply to Objection 3. Athanasius drew up a declaration of faith, not under the form of a symbol, but rather by way of an exposition of doctrine, as appears from his way of speaking. But since it contained briefly the whole truth of faith, it was accepted by the authority of the Sovereign Pontiff, so as to be considered as a rule of faith.

Whether to believe is to think with assent?

Objection 1. It would seem that to believe is not to think with assent. Because the Latin word "cogitatio" [thought] implies a research, for "cogitare" [to think] seems to be equivalent to "coagitare," i.e. "to discuss together." Now Damascene says (De Fide Orth. iv) that faith is "an assent without research." Therefore thinking has no place in the act of faith.

Objection 2. Further, faith resides in the reason, as we shall show further on (II-II:4:2). Now to think is an act of the cogitative power, which belongs to the sensitive faculty, as stated in I:78:4. Therefore thought has nothing to do with faith.

Objection 3. Further, to believe is an act of the intellect, since its object is truth. But assent seems to be an act not of the intellect, but of the will, even as consent is, as stated above (I-II:15:1 ad 3). Therefore to believe is not to think with assent.

On the contrary, This is how "to believe" is defined by Augustine (De Praedest. Sanct. ii).

I answer that, "To think" can be taken in three ways. First, in a general way for any kind of actual consideration of the intellect, as Augustine observes (De Trin. xiv, 7): "By understanding I mean now the faculty whereby we understand when thinking." Secondly, "to think" is more strictly taken for that consideration of the intellect, which is accompanied by some kind of inquiry, and which precedes the intellect's arrival at the stage of perfection that comes with the certitude of sight. On this sense Augustine says (De Trin. xv, 16) that "the Son of God is not called the Thought, but the Word of God. When our thought realizes what we know and takes form therefrom, it becomes our word. Hence the Word of God must be understood without any thinking on the part of God, for there is nothing there that can take form, or be unformed." In this way thought is, properly speaking, the movement of the mind while yet deliberating, and not yet perfected by the clear sight of truth. Since, however, such a movement of the mind may be one of deliberation either about universal notions, which belongs to the intellectual faculty, or about particular matters, which belongs to the sensitive part, hence it is that "to think" is taken secondly for an act of the deliberating intellect, and thirdly for an act of the cogitative power.

Accordingly, if "to think" be understood broadly according to the first sense, then "to think with assent," does not express completely what is meant by "to believe": since, in this way, a man thinks with assent even when he considers what he knows by science [Science is certain knowledge of a demonstrated conclusion through its demonstration.], or understands. If, on the other hand, "to think" be understood in the second way, then this expresses completely the nature of the act of believing. For among the acts belonging to the intellect, some have a firm assent without any such kind of thinking, as when a man considers the things that he knows by science, or understands, for this consideration is already formed. But some acts of the intellect have unformed thought devoid of a firm assent, whether they incline to neither side, as in one who "doubts"; or incline to one side rather than the other, but on account of some slight motive, as in one who "suspects"; or incline to one side yet with fear of the other, as in one who "opines." But this act "to believe," cleaves firmly to one side, in which respect belief has something in common with science and understanding; yet its knowledge does not attain the perfection of clear sight, wherein it agrees with doubt, suspicion and opinion. Hence it is proper to the believer to think with assent: so that the act of believing is distinguished from all the other acts of the intellect, which are about the true or the false.

Reply to Objection 1. Faith has not that research of natural reason which demonstrates what is believed, but a research into those things whereby a man is induced to believe, for instance that such things have been uttered by God and confirmed by miracles.

Reply to Objection 2. "To think" is not taken here for the act of the cogitative power, but for an act of the intellect, as explained above.

Reply to Objection 3. The intellect of the believer is determined to one object, not by the reason, but by the will, wherefore assent is taken here for an act of the intellect as determined to one object by the will.


Whether the act of faith is suitably distinguished as believing God, believing in a God and believing in God?

Objection 1. It would seem that the act of faith is unsuitably distinguished as believing God, believing in a God, and believing in God. For one habit has but one act. Now faith is one habit since it is one virtue. Therefore it is unreasonable to say that there are three acts of faith.

Objection 2. Further, that which is common to all acts of faith should not be reckoned as a particular kind of act of faith. Now "to believe God" is common to all acts of faith, since faith is founded on the First Truth. Therefore it seems unreasonable to distinguish it from certain other acts of faith.

Objection 3. Further, that which can be said of unbelievers, cannot be called an act of faith. Now unbelievers can be said to believe in a God. Therefore it should not be reckoned an act of faith.

Objection 4. Further, movement towards the end belongs to the will, whose object is the good and the end. Now to believe is an act, not of the will, but of the intellect. Therefore "to believe in God," which implies movement towards an end, should not be reckoned as a species of that act.

On the contrary is the authority of Augustine who makes this distinction (De Verb. Dom., Serm. lxi—Tract. xxix in Joan.).

I answer that, The act of any power or habit depends on the relation of that power or habit to its object. Now the object of faith can be considered in three ways. For, since "to believe" is an act of the intellect, in so far as the will moves it to assent, as stated above (Article 1, Reply to Objection 3), the object of faith can be considered either on the part of the intellect, or on the part of the will that moves the intellect.

If it be considered on the part of the intellect, then two things can be observed in the object of faith, as stated above (II-II:1:1). One of these is the material object of faith, and in this way an act of faith is "to believe in a God"; because, as stated above (II-II:1:1) nothing is proposed to our belief, except in as much as it is referred to God. The other is the formal aspect of the object, for it is the medium on account of which we assent to such and such a point of faith; and thus an act of faith is "to believe God," since, as stated above (II-II:1:1) the formal object of faith is the First Truth, to Which man gives his adhesion, so as to assent to Its sake to whatever he believes.

Thirdly, if the object of faith be considered in so far as the intellect is moved by the will, an act of faith is "to believe in God." For the First Truth is referred to the will, through having the aspect of an end.

Reply to Objection 1. These three do not denote different acts of faith, but one and the same act having different relations to the object of faith.

This suffices for the Reply to the Second Objection.

Reply to Objection 3. Unbelievers cannot be said "to believe in a God" as we understand it in relation to the act of faith. For they do not believe that God exists under the conditions that faith determines; hence they do not truly believe in a God, since, as the Philosopher observes (Metaph. ix, text. 22) "to know simple things defectively is not to know them at all."

Reply to Objection 4. As stated above (I-II:9:1) the will moves the intellect and the other powers of the soul to the end: and in this respect an act of faith is "to believe in God."


Whether it is necessary for salvation to believe anything above the natural reason?

Objection 1. It would seem unnecessary for salvation to believe anything above the natural reason. For the salvation and perfection of a thing seem to be sufficiently insured by its natural endowments. Now matters of faith, surpass man's natural reason, since they are things unseen as stated above (II-II:1:4). Therefore to believe seems unnecessary for salvation.

Objection 2. Further, it is dangerous for man to assent to matters, wherein he cannot judge whether that which is proposed to him be true or false, according to Job 12:11: "Doth not the ear discern words?" Now a man cannot form a judgment of this kind in matters of faith, since he cannot trace them back to first principles, by which all our judgments are guided. Therefore it is dangerous to believe in such matters. Therefore to believe is not necessary for salvation.

Objection 3. Further, man's salvation rests on God, according to Psalm 36:39: "But the salvation of the just is from the Lord." Now "the invisible things" of God "are clearly seen, being understood by the things that are made; His eternal power also and Divinity," according to Romans 1:20: and those things which are clearly seen by the understanding are not an object of belief. Therefore it is not necessary for man's salvation, that he should believe certain things.

On the contrary, It is written (Hebrews 11:6): "Without faith it is impossible to please God."

I answer that, Wherever one nature is subordinate to another, we find that two things concur towards the perfection of the lower nature, one of which is in respect of that nature's proper movement, while the other is in respect of the movement of the higher nature. Thus water by its proper movement moves towards the centre (of the earth), while according to the movement of the moon, it moves round the centre by ebb and flow. On like manner the planets have their proper movements from west to east, while in accordance with the movement of the first heaven, they have a movement from east to west. Now the created rational nature alone is immediately subordinate to God, since other creatures do not attain to the universal, but only to something particular, while they partake of the Divine goodness either in "being" only, as inanimate things, or also in "living," and in "knowing singulars," as plants and animals; whereas the rational nature, in as much as it apprehends the universal notion of good and being, is immediately related to the universal principle of being.

Consequently the perfection of the rational creature consists not only in what belongs to it in respect of its nature, but also in that which it acquires through a supernatural participation of Divine goodness. Hence it was said above (I-II:3:8) that man's ultimate happiness consists in a supernatural vision of God: to which vision man cannot attain unless he be taught by God, according to John 6:45: "Every one that hath heard of the Father and hath learned cometh to Me." Now man acquires a share of this learning, not indeed all at once, but by little and little, according to the mode of his nature: and every one who learns thus must needs believe, in order that he may acquire science in a perfect degree; thus also the Philosopher remarks (De Soph. Elench. i, 2) that "it behooves a learner to believe."

Hence in order that a man arrive at the perfect vision of heavenly happiness, he must first of all believe God, as a disciple believes the master who is teaching him.

Reply to Objection 1. Since man's nature is dependent on a higher nature, natural knowledge does not suffice for its perfection, and some supernatural knowledge is necessary, as stated above.

Reply to Objection 2. Just as man assents to first principles, by the natural light of his intellect, so does a virtuous man, by the habit of virtue, judge aright of things concerning that virtue; and in this way, by the light of faith which God bestows on him, a man assents to matters of faith and not to those which are against faith. Consequently "there is no" danger or "condemnation to them that are in Christ Jesus," and whom He has enlightened by faith.

Reply to Objection 3. In many respects faith perceives the invisible things of God in a higher way than natural reason does in proceeding to God from His creatures. Hence it is written (Sirach 3:25): "Many things are shown to thee above the understandings of man."


Whether it is necessary to believe those things which can be proved by natural reason?

Objection 1. It would seem unnecessary to believe those things which can be proved by natural reason. For nothing is superfluous in God's works, much less even than in the works of nature. Now it is superfluous to employ other means, where one already suffices. Therefore it would be superfluous to receive by faith, things that can be known by natural reason.

Objection 2. Further, those things must be believed, which are the object of faith. Now science and faith are not about the same object, as stated above (II-II:1:5). Since therefore all things that can be known by natural reason are an object of science, it seems that there is no need to believe what can be proved by natural reason.

Objection 3. Further, all things knowable scientifically [Science is certain knowledge of a demonstrated conclusion through its demonstration] would seem to come under one head: so that if some of them are proposed to man as objects of faith, in like manner the others should also be believed. But this is not true. Therefore it is not necessary to believe those things which can be proved by natural reason.

On the contrary, It is necessary to believe that God is one and incorporeal: which things philosophers prove by natural reason.

I answer that, It is necessary for man to accept by faith not only things which are above reason, but also those which can be known by reason: and this for three motives. First, in order that man may arrive more quickly at the knowledge of Divine truth. Because the science to whose province it belongs to prove the existence of God, is the last of all to offer itself to human research, since it presupposes many other sciences: so that it would not by until late in life that man would arrive at the knowledge of God. The second reason is, in order that the knowledge of God may be more general. For many are unable to make progress in the study of science, either through dullness of mind, or through having a number of occupations, and temporal needs, or even through laziness in learning, all of whom would be altogether deprived of the knowledge of God, unless Divine things were brought to their knowledge under the guise of faith. The third reason is for the sake of certitude. For human reason is very deficient in things concerning God. A sign of this is that philosophers in their researches, by natural investigation, into human affairs, have fallen into many errors, and have disagreed among themselves. And consequently, in order that men might have knowledge of God, free of doubt and uncertainty, it was necessary for Divine matters to be delivered to them by way of faith, being told to them, as it were, by God Himself Who cannot lie.

Reply to Objection 1. The researches of natural reason do not suffice mankind for the knowledge of Divine matters, even of those that can be proved by reason: and so it is not superfluous if these others be believed.

Reply to Objection 2. Science and faith cannot be in the same subject and about the same object: but what is an object of science for one, can be an object of faith for another, as stated above (II-II:1:5).

Reply to Objection 3. Although all things that can be known by science are of one common scientific aspect, they do not all alike lead man to beatitude: hence they are not all equally proposed to our belief.


Whether man is bound to believe anything explicitly?

Objection 1. It would seem that man is not bound to believe anything explicitly. For no man is bound to do what is not in his power. Now it is not in man's power to believe a thing explicitly, for it is written (Romans 10:14-15): "How shall they believe Him, of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they be sent?" Therefore man is not bound to believe anything explicitly.

Objection 2. Further, just as we are directed to God by faith, so are we by charity. Now man is not bound to keep the precepts of charity, and it is enough if he be ready to fulfil them: as is evidenced by the precept of Our Lord (Matthew 5:39): "If one strike thee on one [Vulgate: 'thy right'] cheek, turn to him also the other"; and by others of the same kind, according to Augustine's exposition (De Serm. Dom. in Monte xix). Therefore neither is man bound to believe anything explicitly, and it is enough if he be ready to believe whatever God proposes to be believed.

Objection 3. Further, the good of faith consists in obedience, according to Romans 1:5: "For obedience to the faith in all nations." Now the virtue of obedience does not require man to keep certain fixed precepts, but it is enough that his mind be ready to obey, according to Psalm 118:60: "I am ready and am not troubled; that I may keep Thy commandments." Therefore it seems enough for faith, too, that man should be ready to believe whatever God may propose, without his believing anything explicitly.

On the contrary, It is written (Hebrews 11:6): "He that cometh to God, must believe that He is, and is a rewarder to them that seek Him."

I answer that, The precepts of the Law, which man is bound to fulfil, concern acts of virtue which are the means of attaining salvation. Now an act of virtue, as stated above (I-II:60:5) depends on the relation of the habit to its object. Again two things may be considered in the object of any virtue; namely, that which is the proper and direct object of that virtue, and that which is accidental and consequent to the object properly so called. Thus it belongs properly and directly to the object of fortitude, to face the dangers of death, and to charge at the foe with danger to oneself, for the sake of the common good: yet that, in a just war, a man be armed, or strike another with his sword, and so forth, is reduced to the object of fortitude, but indirectly.

Accordingly, just as a virtuous act is required for the fulfilment of a precept, so is it necessary that the virtuous act should terminate in its proper and direct object: but, on the other hand, the fulfilment of the precept does not require that a virtuous act should terminate in those things which have an accidental or secondary relation to the proper and direct object of that virtue, except in certain places and at certain times. We must, therefore, say that the direct object of faith is that whereby man is made one of the Blessed, as stated above (II-II:1:8): while the indirect and secondary object comprises all things delivered by God to us in Holy Writ, for instance that Abraham had two sons, that David was the son of Jesse, and so forth.

Therefore, as regards the primary points or articles of faith, man is bound to believe them, just as he is bound to have faith; but as to other points of faith, man is not bound to believe them explicitly, but only implicitly, or to be ready to believe them, in so far as he is prepared to believe whatever is contained in the Divine Scriptures. Then alone is he bound to believe such things explicitly, when it is clear to him that they are contained in the doctrine of faith.

Reply to Objection 1. If we understand those things alone to be in a man's power, which we can do without the help of grace, then we are bound to do many things which we cannot do without the aid of healing grace, such as to love God and our neighbor, and likewise to believe the articles of faith. But with the help of grace we can do this, for this help "to whomsoever it is given from above it is mercifully given; and from whom it is withheld it is justly withheld, as a punishment of a previous, or at least of original, sin," as Augustine states (De Corr. et Grat. v, vi [Cf. Ep. cxc; De Praed. Sanct. viii.]).

Reply to Objection 2. Man is bound to love definitely those lovable things which are properly and directly the objects of charity, namely, God and our neighbor. The objection refers to those precepts of charity which belong, as a consequence, to the objects of charity.

Reply to Objection 3. The virtue of obedience is seated, properly speaking, in the will; hence promptness of the will subject to authority, suffices for the act of obedience, because it is the proper and direct object of obedience. But this or that precept is accidental or consequent to that proper and direct object.


Whether all are equally bound to have explicit faith?

Objection 1. It would seem that all are equally bound to have explicit faith. For all are bound to those things which are necessary for salvation, as is evidenced by the precepts of charity. Now it is necessary for salvation that certain things should be believed explicitly. Therefore all are equally bound to have explicit faith.

Objection 2. Further, no one should be put to test in matters that he is not bound to believe. But simple reasons are sometimes tested in reference to the slightest articles of faith. Therefore all are bound to believe everything explicitly.

Objection 3. Further, if the simple are bound to have, not explicit but only implicit faith, their faith must needs be implied in the faith of the learned. But this seems unsafe, since it is possible for the learned to err. Therefore it seems that the simple should also have explicit faith; so that all are, therefore, equally bound to have explicit faith.

On the contrary, It is written (Job 1:14): "The oxen were ploughing, and the asses feeding beside them," because, as Gregory expounds this passage (Moral. ii, 17), the simple, who are signified by the asses, ought, in matters of faith, to stay by the learned, who are denoted by the oxen.

I answer that, The unfolding of matters of faith is the result of Divine revelation: for matters of faith surpass natural reason. Now Divine revelation reaches those of lower degree through those who are over them, in a certain order; to men, for instance, through the angels, and to the lower angels through the higher, as Dionysius explains (Coel. Hier. iv, vii). On like manner therefore the unfolding of faith must needs reach men of lower degree through those of higher degree. Consequently, just as the higher angels, who enlighten those who are below them, have a fuller knowledge of Divine things than the lower angels, as Dionysius states (Coel. Hier. xii), so too, men of higher degree, whose business it is to teach others, are under obligation to have fuller knowledge of matters of faith, and to believe them more explicitly.

Reply to Objection 1. The unfolding of the articles of faith is not equally necessary for the salvation of all, since those of higher degree, whose duty it is to teach others, are bound to believe explicitly more things than others are.

Reply to Objection 2. Simple persons should not be put to the test about subtle questions of faith, unless they be suspected of having been corrupted by heretics, who are wont to corrupt the faith of simple people in such questions. If, however, it is found that they are free from obstinacy in their heterodox sentiments, and that it is due to their simplicity, it is no fault of theirs.

Reply to Objection 3. The simple have no faith implied in that of the learned, except in so far as the latter adhere to the Divine teaching. Hence the Apostle says (1 Corinthians 4:16): "Be ye followers of me, as I also am of Christ." Hence it is not human knowledge, but the Divine truth that is the rule of faith: and if any of the learned stray from this rule, he does not harm the faith of the simple ones, who think that the learned believe aright; unless the simple hold obstinately to their individual errors, against the faith of the universal Church, which cannot err, since Our Lord said (Luke 22:32): "I have prayed for thee," Peter, "that thy faith fail not."


Whether it is necessary for the salvation of all, that they should believe explicitly in the mystery of Christ?

Objection 1. It would seem that it is not necessary for the salvation of all that they should believe explicitly in the mystery of Christ. For man is not bound to believe explicitly what the angels are ignorant about: since the unfolding of faith is the result of Divine revelation, which reaches man by means of the angels, as stated above (Article 6 and I:111:1). Now even the angels were in ignorance of the mystery of the Incarnation: hence, according to the commentary of Dionysius (Coel. Hier. vii), it is they who ask (Psalm 23:8): "Who is this king of glory?" and (Isaiah 63:1): "Who is this that cometh from Edom?" Therefore men were not bound to believe explicitly in the mystery of Christ's Incarnation.

Objection 2. Further, it is evident that John the Baptist was one of the teachers, and most nigh to Christ, Who said of him (Matthew 11:11) that "there hath not risen among them that are born of women, a greater than" he. Now John the Baptist does not appear to have known the mystery of Christ explicitly, since he asked Christ (Matthew 11:3): "Art Thou He that art to come, or look we for another?" Therefore even the teachers were not bound to explicit faith in Christ.

Objection 3. Further, many gentiles obtained salvation through the ministry of the angels, as Dionysius states (Coel. Hier. ix). Now it would seem that the gentiles had neither explicit nor implicit faith in Christ, since they received no revelation. Therefore it seems that it was not necessary for the salvation of all to believe explicitly in the mystery of Christ.

On the contrary, Augustine says (De Corr. et Gratia vii; Ep. cxc): "Our faith is sound if we believe that no man, old or young is delivered from the contagion of death and the bonds of sin, except by the one Mediator of God and men, Jesus Christ."

I answer that, As stated above (Article 5; II-II:1:8), the object of faith includes, properly and directly, that thing through which man obtains beatitude. Now the mystery of Christ's Incarnation and Passion is the way by which men obtain beatitude; for it is written (Acts 4:12): "There is no other name under heaven given to men, whereby we must be saved." Therefore belief of some kind in the mystery of Christ's Incarnation was necessary at all times and for all persons, but this belief differed according to differences of times and persons. The reason of this is that before the state of sin, man believed, explicitly in Christ's Incarnation, in so far as it was intended for the consummation of glory, but not as it was intended to deliver man from sin by the Passion and Resurrection, since man had no foreknowledge of his future sin. He does, however, seem to have had foreknowledge of the Incarnation of Christ, from the fact that he said (Genesis 2:24): "Wherefore a man shall leave father and mother, and shall cleave to his wife," of which the Apostle says (Ephesians 5:32) that "this is a great sacrament . . . in Christ and the Church," and it is incredible that the first man was ignorant about this sacrament.

But after sin, man believed explicitly in Christ, not only as to the Incarnation, but also as to the Passion and Resurrection, whereby the human race is delivered from sin and death: for they would not, else, have foreshadowed Christ's Passion by certain sacrifices both before and after the Law, the meaning of which sacrifices was known by the learned explicitly, while the simple folk, under the veil of those sacrifices, believed them to be ordained by God in reference to Christ's coming, and thus their knowledge was covered with a veil, so to speak. And, as stated above (II-II:1:7), the nearer they were to Christ, the more distinct was their knowledge of Christ's mysteries.

After grace had been revealed, both learned and simple folk are bound to explicit faith in the mysteries of Christ, chiefly as regards those which are observed throughout the Church, and publicly proclaimed, such as the articles which refer to the Incarnation, of which we have spoken above (II-II:1:8). As to other minute points in reference to the articles of the Incarnation, men have been bound to believe them more or less explicitly according to each one's state and office.

Reply to Objection 1. The mystery of the Kingdom of God was not entirely hidden from the angels, as Augustine observes (Gen. ad lit. v, 19), yet certain aspects thereof were better known to them when Christ revealed them to them.

Reply to Objection 2. It was not through ignorance that John the Baptist inquired of Christ's advent in the flesh, since he had clearly professed his belief therein, saying: "I saw, and I gave testimony, that this is the Son of God" (John 1:34). Hence he did not say: "Art Thou He that hast come?" but "Art Thou He that art to come?" thus saying about the future, not about the past. Likewise it is not to be believed that he was ignorant of Christ's future Passion, for he had already said (John 1:39): "Behold the Lamb of God, behold Him who taketh away the sins [Vulgate: 'sin'] of the world," thus foretelling His future immolation; and since other prophets had foretold it, as may be seen especially in Isaias 53. We may therefore say with Gregory (Hom. xxvi in Evang.) that he asked this question, being in ignorance as to whether Christ would descend into hell in His own Person. But he did not ignore the fact that the power of Christ's Passion would be extended to those who were detained in Limbo, according to Zechariah 9:11: "Thou also, by the blood of Thy testament hast sent forth Thy prisoners out of the pit, wherein there is no water"; nor was he bound to believe explicitly, before its fulfilment, that Christ was to descend thither Himself.

It may also be replied that, as Ambrose observes in his commentary on Luke 7:19, he made this inquiry, not from doubt or ignorance but from devotion: or again, with Chrysostom (Hom. xxxvi in Matth.), that he inquired, not as though ignorant himself, but because he wished his disciples to be satisfied on that point, through Christ: hence the latter framed His answer so as to instruct the disciples, by pointing to the signs of His works.

Reply to Objection 3. Many of the gentiles received revelations of Christ, as is clear from their predictions. Thus we read (Job 19:25): "I know that my Redeemer liveth." The Sibyl too foretold certain things about Christ, as Augustine states (Contra Faust. xiii, 15). Moreover, we read in the history of the Romans, that at the time of Constantine Augustus and his mother Irene a tomb was discovered, wherein lay a man on whose breast was a golden plate with the inscription: "Christ shall be born of a virgin, and in Him, I believe. O sun, during the lifetime of Irene and Constantine, thou shalt see me again" [Cf. Baron, Annal., A.D. 780. If, however, some were saved without receiving any revelation, they were not saved without faith in a Mediator, for, though they did not believe in Him explicitly, they did, nevertheless, have implicit faith through believing in Divine providence, since they believed that God would deliver mankind in whatever way was pleasing to Him, and according to the revelation of the Spirit to those who knew the truth, as stated in Job 35:11: "Who teacheth us more than the beasts of the earth."


Whether it is necessary for salvation to believe explicitly in the Trinity?

Objection 1. It would seem that it was not necessary for salvation to believe explicitly in the Trinity. For the Apostle says (Hebrews 11:6): "He that cometh to God must believe that He is, and is a rewarder to them that seek Him." Now one can believe this without believing in the Trinity. Therefore it was not necessary to believe explicitly in the Trinity.

Objection 2. Further our Lord said (John 17:5-6): "Father, I have manifested Thy name to men," which words Augustine expounds (Tract. cvi) as follows: "Not the name by which Thou art called God, but the name whereby Thou art called My Father," and further on he adds: "In that He made this world, God is known to all nations; in that He is not to be worshipped together with false gods, 'God is known in Judea'; but, in that He is the Father of this Christ, through Whom He takes away the sin of the world, He now makes known to men this name of His, which hitherto they knew not." Therefore before the coming of Christ it was not known that Paternity and Filiation were in the Godhead: and so the Trinity was not believed explicitly.

Objection 3. Further, that which we are bound to believe explicitly of God is the object of heavenly happiness. Now the object of heavenly happiness is the sovereign good, which can be understood to be in God, without any distinction of Persons. Therefore it was not necessary to believe explicitly in the Trinity.

On the contrary, In the Old Testament the Trinity of Persons is expressed in many ways; thus at the very outset of Genesis it is written in manifestation of the Trinity: "Let us make man to Our image and likeness" (Genesis 1:26). Therefore from the very beginning it was necessary for salvation to believe in the Trinity.

I answer that, It is impossible to believe explicitly in the mystery of Christ, without faith in the Trinity, since the mystery of Christ includes that the Son of God took flesh; that He renewed the world through the grace of the Holy Ghost; and again, that He was conceived by the Holy Ghost. Wherefore just as, before Christ, the mystery of Christ was believed explicitly by the learned, but implicitly and under a veil, so to speak, by the simple, so too was it with the mystery of the Trinity. And consequently, when once grace had been revealed, all were bound to explicit faith in the mystery of the Trinity: and all who are born again in Christ, have this bestowed on them by the invocation of the Trinity, according to Matthew 28:19: "Going therefore teach ye all nations, baptizing them in the name of the Father, and of the Son and of the Holy Ghost."

Reply to Objection 1. Explicit faith in those two things was necessary at all times and for all people: but it was not sufficient at all times and for all people.

Reply to Objection 2. Before Christ's coming, faith in the Trinity lay hidden in the faith of the learned, but through Christ and the apostles it was shown to the world.

Reply to Objection 3. God's sovereign goodness as we understand it now through its effects, can be understood without the Trinity of Persons: but as understood in itself, and as seen by the Blessed, it cannot be understood without the Trinity of Persons. Moreover the mission of the Divine Persons brings us to heavenly happiness.


Whether to believe is meritorious?

Objection 1. It would seem that to believe in not meritorious. For the principle of all merit is charity, as stated above (I-II:114:4). Now faith, like nature, is a preamble to charity. Therefore, just as an act of nature is not meritorious, since we do not merit by our natural gifts, so neither is an act of faith.

Objection 2. Further, belief is a mean between opinion and scientific knowledge or the consideration of things scientifically known [Science is a certain knowledge of a demonstrated conclusion through its demonstration.]. Now the considerations of science are not meritorious, nor on the other hand is opinion. Therefore belief is not meritorious.

Objection 3. Further, he who assents to a point of faith, either has a sufficient motive for believing, or he has not. If he has a sufficient motive for his belief, this does not seem to imply any merit on his part, since he is no longer free to believe or not to believe: whereas if he has not a sufficient motive for believing, this is a mark of levity, according to Sirach 19:4: "He that is hasty to give credit, is light of heart," so that, seemingly, he gains no merit thereby. Therefore to believe is by no means meritorious.

On the contrary, It is written (Hebrews 11:33) that the saints "by faith . . . obtained promises," which would not be the case if they did not merit by believing. Therefore to believe is meritorious.

I answer that, As stated above (I-II:114:3; I-II:114:4), our actions are meritorious in so far as they proceed from the free-will moved with grace by God. Therefore every human act proceeding from the free-will, if it be referred to God, can be meritorious. Now the act of believing is an act of the intellect assenting to the Divine truth at the command of the will moved by the grace of God, so that it is subject to the free-will in relation to God; and consequently the act of faith can be meritorious.

Reply to Objection 1. Nature is compared to charity which is the principle of merit, as matter to form: whereas faith is compared to charity as the disposition which precedes the ultimate form. Now it is evident that the subject or the matter cannot act save by virtue of the form, nor can a preceding disposition, before the advent of the form: but after the advent of the form, both the subject and the preceding disposition act by virtue of the form, which is the chief principle of action, even as the heat of fire acts by virtue of the substantial form of fire. Accordingly neither nature nor faith can, without charity, produce a meritorious act; but, when accompanied by charity, the act of faith is made meritorious thereby, even as an act of nature, and a natural act of the free-will.

Reply to Objection 2. Two things may be considered in science: namely the scientist's assent to a scientific fact and his consideration of that fact. Now the assent of science is not subject to free-will, because the scientist is obliged to assent by force of the demonstration, wherefore scientific assent is not meritorious. But the actual consideration of what a man knows scientifically is subject to his free-will, for it is in his power to consider or not to consider. Hence scientific consideration may be meritorious if it be referred to the end of charity, i.e. to the honor of God or the good of our neighbor. On the other hand, in the case of faith, both these things are subject to the free-will so that in both respects the act of faith can be meritorious: whereas in the case of opinion, there is no firm assent, since it is weak and infirm, as the Philosopher observes (Poster. i, 33), so that it does not seem to proceed from a perfect act of the will: and for this reason, as regards the assent, it does not appear to be very meritorious, though it can be as regards the actual consideration.

Reply to Objection 3. The believer has sufficient motive for believing, for he is moved by the authority of Divine teaching confirmed by miracles, and, what is more, by the inward instinct of the Divine invitation: hence he does not believe lightly. He has not, however, sufficient reason for scientific knowledge, hence he does not lose the merit.


Whether reasons in support of what we believe lessen the merit of faith?

Objection 1. It would seem that reasons in support of what we believe lessen the merit of faith. For Gregory says (Hom. xxvi in Evang.) that "there is no merit in believing what is shown by reason." If, therefore, human reason provides sufficient proof, the merit of faith is altogether taken away. Therefore it seems that any kind of human reasoning in support of matters of faith, diminishes the merit of believing.

Objection 2. Further, whatever lessens the measure of virtue, lessens the amount of merit, since "happiness is the reward of virtue," as the Philosopher states (Ethic. i, 9). Now human reasoning seems to diminish the measure of the virtue of faith, since it is essential to faith to be about the unseen, as stated above (II-II:1:5). Now the more a thing is supported by reasons the less is it unseen. Therefore human reasons in support of matters of faith diminish the merit of faith.

Objection 3. Further, contrary things have contrary causes. Now an inducement in opposition to faith increases the merit of faith whether it consist in persecution inflicted by one who endeavors to force a man to renounce his faith, or in an argument persuading him to do so. Therefore reasons in support of faith diminish the merit of faith.

On the contrary, It is written (1 Peter 3:15): "Being ready always to satisfy every one that asketh you a reason of that faith [Vulgate: 'Of that hope which is in you.' St. Thomas' reading is apparently taken from Bede.] and hope which is in you." Now the Apostle would not give this advice, if it would imply a diminution in the merit of faith. Therefore reason does not diminish the merit of faith.

I answer that, As stated above (Article 9), the act of faith can be meritorious, in so far as it is subject to the will, not only as to the use, but also as to the assent. Now human reason in support of what we believe, may stand in a twofold relation to the will of the believer. First, as preceding the act of the will; as, for instance, when a man either has not the will, or not a prompt will, to believe, unless he be moved by human reasons: and in this way human reason diminishes the merit of faith. On this sense it has been said above (I-II:24:3 ad 1; II-II:77:6 ad 2) that, in moral virtues, a passion which precedes choice makes the virtuous act less praiseworthy. For just as a man ought to perform acts of moral virtue, on account of the judgment of his reason, and not on account of a passion, so ought he to believe matters of faith, not on account of human reason, but on account of the Divine authority. Secondly, human reasons may be consequent to the will of the believer. For when a man's will is ready to believe, he loves the truth he believes, he thinks out and takes to heart whatever reasons he can find in support thereof; and in this way human reason does not exclude the merit of faith but is a sign of greater merit. Thus again, in moral virtues a consequent passion is the sign of a more prompt will, as stated above (I-II:24:3 ad 1). We have an indication of this in the words of the Samaritans to the woman, who is a type of human reason: "We now believe, not for thy saying" (John 4:42).

Reply to Objection 1. Gregory is referring to the case of a man who has no will to believe what is of faith, unless he be induced by reasons. But when a man has the will to believe what is of faith on the authority of God alone, although he may have reasons in demonstration of some of them, e.g. of the existence of God, the merit of his faith is not, for that reason, lost or diminished.

Reply to Objection 2. The reasons which are brought forward in support of the authority of faith, are not demonstrations which can bring intellectual vision to the human intellect, wherefore they do not cease to be unseen.

But they remove obstacles to faith, by showing that what faith proposes is not impossible; wherefore such reasons do not diminish the merit or the measure of faith. On the other hand, though demonstrative reasons in support of the preambles of faith [The Leonine Edition reads: 'in support of matters of faith which are however, preambles to the articles of faith, diminish,' etc.], but not of the articles of faith, diminish the measure of faith, since they make the thing believed to be seen, yet they do not diminish the measure of charity, which makes the will ready to believe them, even if they were unseen; and so the measure of merit is not diminished.

Reply to Objection 3. Whatever is in opposition to faith, whether it consist in a man's thoughts, or in outward persecution, increases the merit of faith, in so far as the will is shown to be more prompt and firm in believing. Hence the martyrs had more merit of faith, through not renouncing faith on account of persecution; and even the wise have greater merit of faith, through not renouncing their faith on account of the reasons brought forward by philosophers or heretics in opposition to faith. On the other hand things that are favorable to faith, do not always diminish the promptness of the will to believe, and therefore they do not always diminish the merit of faith.

Whether confession is an act of faith?

Objection 1. It would seem that confession is not an act of faith. For the same act does not belong to different virtues. Now confession belongs to penance of which it is a part. Therefore it is not an act of faith.

Objection 2. Further, man is sometimes deterred by fear or some kind of confusion, from confessing his faith: wherefore the Apostle (Ephesians 6:19) asks for prayers that it may be granted him "with confidence, to make known the mystery of the gospel." Now it belongs to fortitude, which moderates daring and fear, not to be deterred from doing good on account of confusion or fear. Therefore it seems that confession is not an act of faith, but rather of fortitude or constancy.

Objection 3. Further, just as the ardor of faith makes one confess one's faith outwardly, so does it make one do other external good works, for it is written (Galatians 5:6) that "faith . . . worketh by charity." But other external works are not reckoned acts of faith. Therefore neither is confession an act of faith.

On the contrary, A gloss explains the words of 2 Thessalonians 1:11, "and the work of faith in power" as referring to "confession which is a work proper to faith."

I answer that, Outward actions belong properly to the virtue to whose end they are specifically referred: thus fasting is referred specifically to the end of abstinence, which is to tame the flesh, and consequently it is an act of abstinence.

Now confession of those things that are of faith is referred specifically as to its end, to that which concerns faith, according to 2 Corinthians 4:13: "Having the same spirit of faith . . . we believe, and therefore we speak also." For the outward utterance is intended to signify the inward thought. Wherefore, just as the inward thought of matters of faith is properly an act of faith, so too is the outward confession of them.

Reply to Objection 1. A threefold confession is commended by the Scriptures. One is the confession of matters of faith, and this is a proper act of faith, since it is referred to the end of faith as stated above. Another is the confession of thanksgiving or praise, and this is an act of "latria," for its purpose is to give outward honor to God, which is the end of "latria." The third is the confession of sins, which is ordained to the blotting out of sins, which is the end of penance, to which virtue it therefore belongs.

Reply to Objection 2. That which removes an obstacle is not a direct, but an indirect, cause, as the Philosopher proves (Phys. viii, 4). Hence fortitude which removes an obstacle to the confession of faith, viz. fear or shame, is not the proper and direct cause of confession, but an indirect cause so to speak.

Reply to Objection 3. Inward faith, with the aid of charity, causes all outward acts of virtue, by means of the other virtues, commanding, but not eliciting them; whereas it produces the act of confession as its proper act, without the help of any other virtue.


Whether confession of faith is necessary for salvation?

Objection 1. It would seem that confession of faith is not necessary for salvation. For, seemingly, a thing is sufficient for salvation, if it is a means of attaining the end of virtue. Now the proper end of faith is the union of the human mind with Divine truth, and this can be realized without any outward confession. Therefore confession of faith is not necessary for salvation.

Objection 2. Further, by outward confession of faith, a man reveals his faith to another man. But this is unnecessary save for those who have to instruct others in the faith. Therefore it seems that the simple folk are not bound to confess the faith.

Objection 3. Further, whatever may tend to scandalize and disturb others, is not necessary for salvation, for the Apostle says (1 Corinthians 10:32): "Be without offense to the Jews and to the gentiles and to the Church of God." Now confession of faith sometimes causes a disturbance among unbelievers. Therefore it is not necessary for salvation.

On the contrary, The Apostle says (Romans 10:10): "With the heart we believe unto justice; but with the mouth, confession is made unto salvation."

I answer that, Things that are necessary for salvation come under the precepts of the Divine law. Now since confession of faith is something affirmative, it can only fall under an affirmative precept. Hence its necessity for salvation depends on how it falls under an affirmative precept of the Divine law. Now affirmative precepts as stated above (I-II:71:5 ad 3; I-II:88:1 ad 2) do not bind for always, although they are always binding; but they bind as to place and time according to other due circumstances, in respect of which human acts have to be regulated in order to be acts of virtue.

Thus then it is not necessary for salvation to confess one's faith at all times and in all places, but in certain places and at certain times, when, namely, by omitting to do so, we would deprive God of due honor, or our neighbor of a service that we ought to render him: for instance, if a man, on being asked about his faith, were to remain silent, so as to make people believe either that he is without faith, or that the faith is false, or so as to turn others away from the faith; for in such cases as these, confession of faith is necessary for salvation.

Reply to Objection 1. The end of faith, even as of the other virtues, must be referred to the end of charity, which is the love of God and our neighbor. Consequently when God's honor and our neighbor's good demand, man should not be contented with being united by faith to God's truth, but ought to confess his faith outwardly.

Reply to Objection 2. In cases of necessity where faith is in danger, every one is bound to proclaim his faith to others, either to give good example and encouragement to the rest of the faithful, or to check the attacks of unbelievers: but at other times it is not the duty of all the faithful to instruct others in the faith.

Reply to Objection 3. There is nothing commendable in making a public confession of one's faith, if it causes a disturbance among unbelievers, without any profit either to the faith or to the faithful. Hence Our Lord said (Matthew 7:6): "Give not that which is holy to dogs, neither cast ye your pearls before swine . . . lest turning upon you, they tear you." Yet, if there is hope of profit to the faith, or if there be urgency, a man should disregard the disturbance of unbelievers, and confess his faith in public. Hence it is written (Matthew 15:12) that when the disciples had said to Our Lord that "the Pharisee, when they heard this word, were scandalized," He answered: "Let them alone, they are blind, and leaders of the blind."

Whether this is a fitting definition of faith: "Faith is the substance of things to be hoped for, the evidence of things that appear not?"

Objection 1. It would seem that the Apostle gives an unfitting definition of faith (Hebrews 11:1) when he says: "Faith is the substance of things to be hoped for, the evidence of things that appear not." For no quality is a substance: whereas faith is a quality, since it is a theological virtue, as stated above (I-II:62:3). Therefore it is not a substance.

Objection 2. Further, different virtues have different objects. Now things to be hoped for are the object of hope. Therefore they should not be included in a definition of faith, as though they were its object.

Objection 3. Further, faith is perfected by charity rather than by hope, since charity is the form of faith, as we shall state further on (Article 3). Therefore the definition of faith should have included the thing to be loved rather than the thing to be hoped for.

Objection 4. Further, the same thing should not be placed in different genera. Now "substance" and "evidence" are different genera, and neither is subalternate to the other. Therefore it is unfitting to state that faith is both "substance" and "evidence."

Objection 5. Further, evidence manifests the truth of the matter for which it is adduced. Now a thing is said to be apparent when its truth is already manifest. Therefore it seems to imply a contradiction to speak of "evidence of things that appear not": and so faith is unfittingly defined.

On the contrary, The authority of the Apostle suffices.

I answer that, Though some say that the above words of the Apostle are not a definition of faith, yet if we consider the matter aright, this definition overlooks none of the points in reference to which faith can be defined, albeit the words themselves are not arranged in the form of a definition, just as the philosophers touch on the principles of the syllogism, without employing the syllogistic form.

In order to make this clear, we must observe that since habits are known by their acts, and acts by their objects, faith, being a habit, should be defined by its proper act in relation to its proper object. Now the act of faith is to believe, as stated above (II-II:2:3), which is an act of the intellect determinate to one object of the will's command. Hence an act of faith is related both to the object of the will, i.e. to the good and the end, and to the object of the intellect, i.e. to the true. And since faith, through being a theological virtues, as stated above (I-II:62:2), has one same thing for object and end, its object and end must, of necessity, be in proportion to one another. Now it has been already stated (II-II:1:4) that the object of faith is the First Truth, as unseen, and whatever we hold on account thereof: so that it must needs be under the aspect of something unseen that the First Truth is the end of the act of faith, which aspect is that of a thing hoped for, according to the Apostle (Romans 8:25): "We hope for that which we see not": because to see the truth is to possess it. Now one hopes not for what one has already, but for what one has not, as stated above (I-II:67:4). Accordingly the relation of the act of faith to its end which is the object of the will, is indicated by the words: "Faith is the substance of things to be hoped for." For we are wont to call by the name of substance, the first beginning of a thing, especially when the whole subsequent thing is virtually contained in the first beginning; for instance, we might say that the first self-evident principles are the substance of science, because, to wit, these principles are in us the first beginnings of science, the whole of which is itself contained in them virtually. On this way then faith is said to be the "substance of things to be hoped for," for the reason that in us the first beginning of things to be hoped for is brought about by the assent of faith, which contains virtually all things to be hoped for. Because we hope to be made happy through seeing the unveiled truth to which our faith cleaves, as was made evident when we were speaking of happiness (I-II:3:8; I-II:4:3).

The relationship of the act of faith to the object of the intellect, considered as the object of faith, is indicated by the words, "evidence of things that appear not," where "evidence" is taken for the result of evidence. For evidence induces the intellect to adhere to a truth, wherefore the firm adhesion of the intellect to the non-apparent truth of faith is called "evidence" here. Hence another reading has "conviction," because to wit, the intellect of the believer is convinced by Divine authority, so as to assent to what it sees not. Accordingly if anyone would reduce the foregoing words to the form of a definition, he may say that "faith is a habit of the mind, whereby eternal life is begun in us, making the intellect assent to what is non-apparent."

In this way faith is distinguished from all other things pertaining to the intellect. For when we describe it as "evidence," we distinguish it from opinion, suspicion, and doubt, which do not make the intellect adhere to anything firmly; when we go on to say, "of things that appear not," we distinguish it from science and understanding, the object of which is something apparent; and when we say that it is "the substance of things to be hoped for," we distinguish the virtue of faith from faith commonly so called, which has no reference to the beatitude we hope for.

Whatever other definitions are given of faith, are explanations of this one given by the Apostle. For when Augustine says (Tract. xl in Joan.: QQ. Evang. ii, qu. 39) that "faith is a virtue whereby we believe what we do not see," and when Damascene says (De Fide Orth. iv, 11) that "faith is an assent without research," and when others say that "faith is that certainty of the mind about absent things which surpasses opinion but falls short of science," these all amount to the same as the Apostle's words: "Evidence of things that appear not"; and when Dionysius says (Div. Nom. vii) that "faith is the solid foundation of the believer, establishing him in the truth, and showing forth the truth in him," comes to the same as "substance of things to be hoped for."

Reply to Objection 1. "Substance" here does not stand for the supreme genus condivided with the other genera, but for that likeness to substance which is found in each genus, inasmuch as the first thing in a genus contains the others virtually and is said to be the substance thereof.

Reply to Objection 2. Since faith pertains to the intellect as commanded by the will, it must needs be directed, as to its end, to the objects of those virtues which perfect the will, among which is hope, as we shall prove further on (II-II:18:1. For this reason the definition of faith includes the object of hope.

Reply to Objection 3. Love may be of the seen and of the unseen, of the present and of the absent. Consequently a thing to be loved is not so adapted to faith, as a thing to be hoped for, since hope is always of the absent and the unseen.

Reply to Objection 4. "Substance" and "evidence" as included in the definition of faith, do not denote various genera of faith, nor different acts, but different relationships of one act to different objects, as is clear from what has been said.

Reply to Objection 5. Evidence taken from the proper principles of a thing, make it apparent, whereas evidence taken from Divine authority does not make a thing apparent in itself, and such is the evidence referred to in the definition of faith.


Whether faith resides in the intellect?

Objection 1. It would seem that faith does not reside in the intellect. For Augustine says (De Praedest. Sanct. v) that "faith resides in the believer's will." Now the will is a power distinct from the intellect. Therefore faith does not reside in the intellect.

Objection 2. Further, the assent of faith to believe anything, proceeds from the will obeying God. Therefore it seems that faith owes all its praise to obedience. Now obedience is in the will. Therefore faith is in the will, and not in the intellect.

Objection 3. Further, the intellect is either speculative or practical. Now faith is not in the speculative intellect, since this is not concerned with things to be sought or avoided, as stated in De Anima iii, 9, so that it is not a principle of operation, whereas "faith . . . worketh by charity" (Galatians 5:6). Likewise, neither is it in the practical intellect, the object of which is some true, contingent thing, that can be made or done. For the object of faith is the Eternal Truth, as was shown above (II-II:1:1). Therefore faith does not reside in the intellect.

On the contrary, Faith is succeeded by the heavenly vision, according to 1 Corinthians 13:12: "We see now through a glass in a dark manner; but then face to face." Now vision is in the intellect. Therefore faith is likewise.

I answer that, Since faith is a virtue, its act must needs be perfect. Now, for the perfection of an act proceeding from two active principles, each of these principles must be perfect: for it is not possible for a thing to be sawn well, unless the sawyer possess the art, and the saw be well fitted for sawing. Now, in a power of the soul, which is related to opposite objects, a disposition to act well is a habit, as stated above (I-II:49:4 ad 1,2,3). Wherefore an act that proceeds from two such powers must be perfected by a habit residing in each of them. Again, it has been stated above (II-II:2:2) that to believe is an act of the intellect inasmuch as the will moves it to assent. And this act proceeds from the will and the intellect, both of which have a natural aptitude to be perfected in this way. Consequently, if the act of faith is to be perfect, there needs to be a habit in the will as well as in the intellect: even as there needs to be the habit of prudence in the reason, besides the habit of temperance in the concupiscible faculty, in order that the act of that faculty be perfect. Now, to believe is immediately an act of the intellect, because the object of that act is "the true," which pertains properly to the intellect. Consequently faith, which is the proper principle of that act, must needs reside in the intellect.

Reply to Objection 1. Augustine takes faith for the act of faith, which is described as depending on the believer's will, in so far as his intellect assents to matters of faith at the command of the will.

Reply to Objection 2. Not only does the will need to be ready to obey but also the intellect needs to be well disposed to follow the command of the will, even as the concupiscible faculty needs to be well disposed in order to follow the command of reason; hence there needs to be a habit of virtue not only in the commanding will but also in the assenting intellect.

Reply to Objection 3. Faith resides in the speculative intellect, as evidenced by its object. But since this object, which is the First Truth, is the end of all our desires and actions, as Augustine proves (De Trin. i, 8), it follows that faith worketh by charity just as "the speculative intellect becomes practical by extension" (De Anima iii, 10).


Whether charity is the form of faith?

Objection 1. It would seem that charity is not the form of faith. For each thing derives its species from its form. When therefore two things are opposite members of a division, one cannot be the form of the other. Now faith and charity are stated to be opposite members of a division, as different species of virtue (1 Corinthians 13:13). Therefore charity is not the form of faith.

Objection 2. Further, a form and the thing of which it is the form are in one subject, since together they form one simply. Now faith is in the intellect, while charity is in the will. Therefore charity is not the form of faith.

Objection 3. Further, the form of a thing is a principle thereof. Now obedience, rather than charity, seems to be the principle of believing, on the part of the will, according to Romans 1:5: "For obedience to the faith in all nations." Therefore obedience rather than charity, is the form of faith.

On the contrary, Each thing works through its form. Now faith works through charity. Therefore the love of charity is the form of faith.

I answer that, As appears from what has been said above (I-II:1:3; I-II:18:6), voluntary acts take their species from their end which is the will's object. Now that which gives a thing its species, is after the manner of a form in natural things. Wherefore the form of any voluntary act is, in a manner, the end to which that act is directed, both because it takes its species therefrom, and because the mode of an action should correspond proportionately to the end. Now it is evident from what has been said (Article 1), that the act of faith is directed to the object of the will, i.e. the good, as to its end: and this good which is the end of faith, viz. the Divine Good, is the proper object of charity. Therefore charity is called the form of faith in so far as the act of faith is perfected and formed by charity.

Reply to Objection 1. Charity is called the form of faith because it quickens the act of faith. Now nothing hinders one act from being quickened by different habits, so as to be reduced to various species in a certain order, as stated above (I-II:18:6; I-II:18:7; I-II:61:2) when we were treating of human acts in general.

Reply to Objection 2. This objection is true of an intrinsic form. But it is not thus that charity is the form of faith, but in the sense that it quickens the act of faith, as explained above.

Reply to Objection 3. Even obedience, and hope likewise, and whatever other virtue might precede the act of faith, is quickened by charity, as we shall show further on (II-II:23:8, and consequently charity is spoken of as the form of faith.
