The following lines, it is scarcely necessary to say, are intended to represent the celibate rules of the Catholic clergy, the refusal of the Communion in both kinds, and the doctrine of Transubstantiation. That Swift's humour should show some coarseness and apathy towards the feelings of others, need not surprise us: but he rarely sinks to the same level of dulness and commonplace. Those who accept the doctrine will be offended: those who do not, will regret that Swift's genius should have descended to such trifling. It is curious that in the Apology (1709) he resents with some bitterness the accusation that he had borrowed from (Villiers) Duke of Buckingham the idea of the burlesque of transubstantiation, and is at needless pains to disprove by dates his indebtedness to any one for an idea which has been part of the baser currency of ridicule from Luther's time till now. The passage occurs in Buckingham's Dialogue between himself and a priest. To prove the absurdity of Transubstantiation, the duke maintains that a cork he has just drawn is a horse: and the turns of phrase are sufficiently like Swift's to make the coincidence remarkable.
