6. These are the words of Dionysius. But Irenæus, in the first book of his work Against Heresies, gives some more abominable false doctrines of the same man, and in the third book relates a story which deserves to be recorded. He says, on the authority of Polycarp, that the apostle John once entered a bath to bathe; but, learning that Cerinthus was within, he sprang from the place and rushed out of the door, for he could not bear to remain under the same roof with him. And he advised those that were with him to do the same, saying, “Let us flee, lest the bath fall; for Cerinthus, the enemy of the truth, is within.”
