47. See therefore, and remember with the most watchful care, how Petilianus has made no answer to that very question, which he proposes to himself in such terms as to seem to make it a starting-point from which to say something. For the former question he has dismissed altogether, and has not wished to speak of it to us, because I suppose it was beyond his power; nor is he at any time, up to the very end of his volume, going to say anything about it, though he quoted it from the first part of my epistle as though it were a matter calling for refutation. For even though he has added the two words which he accused me of having suppressed, as though they were the strongest bulwarks of his position, he yet lies wholly defenceless, unable to find any answer to make when he is asked, If the conscience of one that gives in holiness is what we look for to cleanse the conscience of the recipient, where are we to find means for cleansing the conscience of the man who is unacquainted with the conscience of him that gives, but not in holiness? and if it be the case that any one who has received his faith from one that is faithless, receives not faith but guilt, from what source is he to receive not guilt but faith, who is unwittingly baptized by one that is faithless? To this question it has long been manifest from what he says that he has made no answer.
