21. Meanwhile, thou gavest her yet another answer, as I remember--for I pass over many things, hastening on to those things which more strongly impel me to confess to thee--and many things I have simply forgotten. But thou gavest her then another answer, by a priest of thine, a certain bishop reared in thy Church and well versed in thy books. When that woman had begged him to agree to have some discussion with me, to refute my errors, to help me to unlearn evil and to learn the good- - for it was his habit to do this when he found people ready to receive it--he refused, very prudently, as I afterward realized. For he answered that I was still unteachable, being inflated with the novelty of that heresy, and that I had already perplexed divers inexperienced persons with vexatious questions, as she herself had told him. "But let him alone for a time," he said, "only pray God for him. He will of his own accord, by reading, come to discover what an error it is and how great its impiety is." He went on to tell her at the same time how he himself, as a boy, had been given over to the Manicheans by his misguided mother and not only had read but had even copied out almost all their books. Yet he had come to see, without external argument or proof from anyone else, how much that sect was to be shunned--and had shunned it. When he had said this she was not satisfied, but repeated more earnestly her entreaties, and shed copious tears, still beseeching him to see and talk with me. Finally the bishop, a little vexed at her importunity, exclaimed, "Go your way; as you live, it cannot be that the son of these tears should perish." As she often told me afterward, she accepted this answer as though it were a voice from heaven.
