text: That is the protestant view.  One sacrifices at an altar.  That's why its shaped like an altar -for sacrifice.  If there is no sacrifice, there is no need for a priest.  A lay preside is totally sufficient to lead a meal.  (NB- Perhaps that's the goal?  The destruction of the priesthood?  Just a thought...).  That fact that we are even discussing this difference shows protestantized Catholic thought and worship has become.  Another fruit of VII no doubt.
