For though I took no pains to learn what he spake, but only to hear how he spake (for that empty care alone was left me, despairing of a way, open for man, to Thee), yet together with the words which I would choose, came also into my mind the things which I would refuse; for I could not separate them. And while I opened my heart to admit "how eloquently he spake," there also entered "how truly he spake"; but this by degrees. For first, these things also had now begun to appear to me capable of defence; and the Catholic faith, for which I had thought nothing could be said against the Manichees' objections, I now thought might be maintained without shamelessness; especially after I had heard one or two places of the Old Testament resolved, and ofttimes "in a figure," which when I understood literally, I was slain spiritually. Very many places then of those books having been explained, I now blamed my despair, in believing that no answer could be given to such as hated and scoffed at the Law and the Prophets. Yet did I not therefore then see that the Catholic way was to be held, because it also could find learned maintainers, who could at large and with some show of reason answer objections; nor that what I held was therefore to be condemned, because both sides could be maintained. For the Catholic cause seemed to me in such sort not vanquished, as still not as yet to be victorious.

Hereupon I earnestly bent my mind, to see if in any way I could by any certain proof convict the Manichees of falsehood. Could I once have conceived a spiritual substance, all their strongholds had been beaten down, and cast utterly out of my mind; but I could not. Notwithstanding, concerning the frame of this world, and the whole of nature, which the senses of the flesh can reach to, as I more and more considered and compared things, I judged the tenets of most of the philosophers to have been much more probable. So then after the manner of the Academics (as they are supposed) doubting of every thing, and wavering between all, I settled so far, that the Manichees were to be abandoned; judging that, even while doubting, I might not continue in that sect, to which I already preferred some of the philosophers; to which philosophers notwithstanding, for that they were without the saving Name of Christ, I utterly refused to commit the cure of my sick soul. I determined therefore so long to be a Catechumen in the Catholic Church, to which I had been commended by my parents, till something certain should dawn upon me, whither I might steer my course.
