By St. Augustine of Hippo
(The Confessions, Bk. 5, Chs. 22-25)
Then began I assiduously to practice that for which I came to Rome — the teaching of rhetoric... When, therefore, they of Milan had sent to Rome to the prefect of the city, to provide them with a teacher of rhetoric for their city, and to dispatch him at the public expense, I made interest through those identical persons, drunk with Manichaean vanities, to be freed from whom I was going away — neither of us, however, being aware of it — that Symmachus, the then prefect, having proved me by proposing a subject, would send me.
And to Milan I came, unto Ambrose the bishop, known to the whole world as among the best of men, Your devout servant; whose eloquent discourse did at that time strenuously dispense unto Your people the flour of Your wheat, the "gladness" of Your "oil," and the sober intoxication of Your "wine." To him was I unknowingly led by You, that by him I might knowingly be led to You. That man of God received me like a father, and looked with a benevolent and episcopal kindliness on my change of abode. And I began to love him, not at first, indeed, as a teacher of the truth — which I entirely despaired of in Your Church, — but as a man friendly to myself.
And I studiously hearkened to him preaching to the people, not with the motive I should, but, as it were, trying to discover whether his eloquence came up to the fame thereof, or flowed fuller or lower than was asserted; and I hung on his words intently, but of the matter I was but as a careless and contemptuous spectator; and I was delighted with the pleasantness of his speech, more erudite, yet less cheerful and soothing in manner, than that of Faustus. Of the matter, however, there could be no comparison; for the latter was straying amid Manichaean deceptions, while the former was teaching salvation most soundly. But "salvation is far from the wicked," such as I then stood before him; and yet I was drawing nearer gradually and unconsciously.
For although I took no trouble to learn what he spoke, but only to hear how he spoke (for that empty care alone remained to me, despairing of a way accessible for man to You), yet, together with the words which I prized, there came into my mind also the things about which I was careless; for I could not separate them. And while I opened my heart to admit "how skillfully he spoke," there also entered with it, but gradually, "and how truly he spoke!" For first, these things also had begun to appear to me to be defensible; and the Catholic faith, for which I had fancied nothing could be said against the attacks of the Manichaeans, I now conceived might be maintained without presumption; especially after I had heard one or two parts of the Old Testament explained, and often allegorically — which when I accepted literally, I was "killed" spiritually. Many places, then, of those books having been expounded to me, I now blamed my despair in having believed that no reply could be made to those who hated and derided the Law and the Prophets. Yet I did not then see that for that reason the Catholic way was to be held because it had its learned advocates, who could at length, and not irrationally, answer objections; nor that what I held ought therefore to be condemned because both sides were equally defensible. For that way did not appear to me to be vanquished; nor yet did it seem to me to be victorious.
Hereupon did I earnestly bend my mind to see if in any way I could possibly prove the Manichaeans guilty of falsehood. Could I have realized a spiritual substance, all their strongholds would have been beaten down, and cast utterly out of my mind; but I could not. But yet, concerning the body of this world, and the whole of nature, which the senses of the flesh can attain unto, I, now more and more considering and comparing things, judged that the greater part of the philosophers held much the more probable opinions. So, then, after the manner of the Academics (as they are supposed), doubting of everything and fluctuating between all, I decided that the Manichaeans were to be abandoned; judging that, even while in that period of doubt, I could not remain in a sect to which I preferred some of the philosophers; to which philosophers, however, because they were without the saving name of Christ, I utterly refused to commit the cure of my fainting soul. I resolved, therefore, to be a catechumen in the Catholic Church, which my parents had commended to me, until something settled should manifest itself to me whither I might steer my course.
