1. Of all other heresies which have departed from the truth it is acknowledged that they have but devised a madness, and their irreligiousness has long since become notorious to all men. For that their authors went out from us, it plainly follows, as the blessed John has written, that they never thought nor now think with us. Wherefore, as saith the Saviour, in that they gather not with us, they scatter with the devil, and keep an eye on those who slumber, that, by this second sowing of their own mortal poison, they may have companions in death. But, whereas one heresy, and that the last, which has now risen as harbinger of Antichrist, the Arian, as it is called, considering that other heresies, her elder sisters, have been openly proscribed, in her craft and cunning, affects to array herself in Scripture language, like her father the devil, and is forcing her way back into the Church’s paradise,—that with the pretence of Christianity, her smooth sophistry (for reason she has none) may deceive men into wrong thoughts of Christ,—nay, since she has already seduced certain of the foolish, not only to corrupt their ears, but even to take and eat with Eve, till in their ignorance which ensues they think bitter sweet, and admire this loathsome heresy, on this account I have thought it necessary, at your request, to unrip ‘the folds of its breast-plate,’ and to shew the ill savour of its folly. So while those who are far from it may continue to shun it, those whom it has deceived may repent; and, opening the eyes of their heart, may understand that darkness is not light, nor falsehood truth, nor Arianism good; nay, that those who call these men Christians are in great and grievous error, as neither having studied Scripture, nor understanding Christianity at all, and the faith which it contains.
