And all admired his priestly care.
And standing on the altar high,
‘Lo, what a fiend is here!' said he:
‘One who sets reason up for judge
Of our most holy mystery.'
The weeping child could not be heard,
The weeping parents wept in vain:
They stripped him to his little shirt,
And bound him in an iron chain,
And burned him in a holy place
Where many had been burned before;
The weeping parents wept in vain.
Are such things done on Albion's shore?
The final line, a  rhetorical question  begs the response, ‘yes, of course’. The burning isn’t to be taken literally, but the punitive Church establishment was a fact. 
 The question is phrased mildly, with mock-innocence. The name  Albion  tends to be used in a romantic literary context, though its application here is purely ironic.
