5 Moreover, that this Marcus compounds philters and love-potions, in order to insult the persons of some of these women, if not of all, those of them who have returned to the Church of God— a thing which frequently occurs— have acknowledged, confessing, too, that they have been defiled by him, and that they were filled with a burning passion towards him. A sad example of this occurred in the case of a certain Asiatic, one of our deacons, who had received him (Marcus) into his house. His wife, a woman of remarkable beauty, fell a victim both in mind and body to this magician, and, for a long time, travelled about with him. At last, when, with no small difficulty, the brethren had converted her, she spent her whole time in the exercise of public confession, weeping over and lamenting the defilement which she had received from this magician.
