Arrival of Monnica at Milan; her obedience to St. Ambrose, and his value for her; St. Ambrose's habits; Augustine's gradual abandonment of error; finds that he has blamed the Church Catholic wrongly; desire of absolute certainty; how shaken in his worldly pursuits; God's guidance of his friend Alypius; Augustine debates with himself and his friends about their mode of life; his inveterate sins, and dread of judgment.
I however certainly had no opportunity of enquiring what I wished of that so holy oracle of Thine, his breast, unless the thing might be answered briefly. But those tides in me, to be poured out to him, required his full leisure, and never found it. I heard him indeed every Lord's day, rightly expounding the Word of truth among the people; and I was more and more convinced that all the knots of those crafty calumnies, which those our deceivers had knit against the Divine Books, could be unravelled. But when I understood withal, that "man created by Thee, after Thine own image," was not so understood by Thy spiritual sons, whom of the Catholic Mother Thou hast born again through grace, as though they believed and conceived of Thee as bounded by human shape (although what a spiritual substance should be I had not even a faint or shadowy notion); yet, with joy I blushed at having so many years barked not against the Catholic faith, but against the fictions of carnal imaginations. For so rash and impious had I been, that what I ought by enquiring to have learned, I had pronounced on, condemning. For Thou, Most High, and most near; most secret, and most present; Who hast not limbs some larger, some smaller, but art wholly every where, and no where in space, art not of such corporeal shape, yet hast Thou made man after Thine own image; and behold, from head to foot is he contained in space.
Ignorant then how this Thy image should subsist, I should have knocked and proposed the doubt, how it was to be believed, not insultingly opposed it, as if believed. Doubt, then, what to hold for certain, the more sharply gnawed my heart, the more ashamed I was, that so long deluded and deceived by the promise of certainties, I had with childish error and vehemence, prated of so many uncertainties. For that they were falsehoods became clear to me later. However I was certain that they were uncertain, and that I had formerly accounted them certain, when with a blind contentiousness, I accused Thy Catholic Church, whom I now discovered, not indeed as yet to teach truly, but at least not to teach that for which I had grievously censured her. So I was confounded, and converted: and I joyed, O my God, that the One Only Church, the body of Thine Only Son (wherein the name of Christ had been put upon me as an infant), had no taste for infantine conceits; nor in her sound doctrine maintained any tenet which should confine Thee, the Creator of all, in space, however great and large, yet bounded every where by the limits of a human form.
I joyed also that the old Scriptures of the law and the Prophets were laid before me, not now to be perused with that eye to which before they seemed absurd, when I reviled Thy holy ones for so thinking, whereas indeed they thought not so: and with joy I heard Ambrose in his sermons to the people, oftentimes most diligently recommend this text for a rule, The letter killeth, but the Spirit giveth life; whilst he drew aside the mystic veil, laying open spiritually what, according to the letter, seemed to teach something unsound; teaching herein nothing that offended me, though he taught what I knew not as yet, whether it were true. For I kept my heart from assenting to any thing, fearing to fall headlong; but by hanging in suspense I was the worse killed. For I wished to be as assured of the things I saw not, as I was that seven and three are ten. For I was not so mad as to think that even this could not be comprehended; but I desired to have other things as clear as this, whether things corporeal, which were not present to my senses, or spiritual, whereof I knew not how to conceive, except corporeally. And by believing might I have been cured, that so the eyesight of my soul being cleared, might in some way be directed to Thy truth, which abideth always, and in no part faileth. But as it happens that one who has tried a bad physician, fears to trust himself with a good one, so was it with the health of my soul, which could not be healed but by believing, and lest it should believe falsehoods, refused to be cured; resisting Thy hands, who hast prepared the medicines of faith, and hast applied them to the diseases of the whole world, and given unto them so great authority.
Being led, however, from this to prefer the Catholic doctrine, I felt that her proceeding was more unassuming and honest, in that she required to be believed things not demonstrated (whether it was that they could in themselves be demonstrated but not to certain persons, or could not at all be), whereas among the Manichees our credulity was mocked by a promise of certain knowledge, and then so many most fabulous and absurd things were imposed to be believed, because they could not be demonstrated. Then Thou, O Lord, little by little with most tender and most merciful hand, touching and composing my heart, didst persuade me -- considering what innumerable things I believed, which I saw not, nor was present while they were done, as so many things in secular history, so many reports of places and of cities, which I had not seen; so many of friends, so many of physicians, so many continually of other men, which unless we should believe, we should do nothing at all in this life; lastly, with how unshaken an assurance I believed of what parents I was born, which I could not know, had I not believed upon hearsay -- considering all this, Thou didst persuade me, that not they who believed Thy Books (which Thou hast established in so great authority among almost all nations), but they who believed them not, were to be blamed; and that they were not to be heard, who should say to me, "How knowest thou those Scriptures to have been imparted unto mankind by the Spirit of the one true and most true God?" For this very thing was of all most to be believed, since no contentiousness of blasphemous questionings, of all that multitude which I had read in the self-contradicting philosophers, could wring this belief from me, "That Thou art" whatsoever Thou wert (what I knew not), and "That the government of human things belongs to Thee."
This I believed, sometimes more strongly, more weakly other-whiles; yet I ever believed both that Thou wert, and hadst a care of us; though I was ignorant, both what was to be thought of Thy substance, and what way led or led back to Thee. Since then we were too weak by abstract reasonings to find out truth: and for this very cause needed the authority of Holy Writ; I had now begun to believe that Thou wouldest never have given such excellency of authority to that Writ in all lands, hadst Thou not willed thereby to be believed in, thereby sought. For now what things, sounding strangely in the Scripture, were wont to offend me, having heard divers of them expounded satisfactorily, I referred to the depth of the mysteries, and its authority appeared to me the more venerable, and more worthy of religious credence, in that, while it lay open to all to read, it reserved the majesty of its mysteries within its profounder meaning, stooping to all in the great plainness of its words and lowliness of its style, yet calling forth the intensest application of such as are not light of heart; that so it might receive all in its open bosom, and through narrow passages waft over towards Thee some few, yet many more than if it stood not aloft on such a height of authority, nor drew multitudes within its bosom by its holy lowliness. These things I thought on, and Thou wert with me; I sighed, and Thou heardest me; I wavered, and Thou didst guide me; I wandered through the broad way of the world, and Thou didst not forsake me.
