I would lay open before my God that nine-and-twentieth year of mine age. There had then come to Carthage a certain Bishop of the Manichees, Faustus by name, a great snare of the Devil, and many were entangled by him through that lure of his smooth language: which though I did commend, yet could I separate from the truth of the things which I was earnest to learn: nor did I so much regard the service of oratory as the science which this Faustus, so praised among them, set before me to feed upon. Fame had before bespoken him most knowing in all valuable learning, and exquisitely skilled in the liberal sciences. And since I had read and well remembered much of the philosophers, I compared some things of theirs with those long fables of the Manichees, and found the former the more probable; even although they could only prevail so far as to make judgment of this lower world, the Lord of it they could by no means find out. For Thou art great, O Lord, and hast respect unto the humble, but the proud Thou beholdest afar off. Nor dost Thou draw near, but to the contrite in heart, nor art found by the proud, no, not though by curious skill they could number the stars and the sand, and measure the starry heavens, and track the courses of the planets.

For with their understanding and wit, which Thou bestowedst on them, they search out these things; and much have they found out; and foretold, many years before, eclipses of those luminaries, the sun and moon, -- what day and hour, and how many digits, -- nor did their calculation fail; and it came to pass as they foretold; and they wrote down the rules they had found out, and these are read at this day, and out of them do others foretell in what year and month of the year, and what day of the month, and what hour of the day, and what part of its light, moon or sun is to be eclipsed, and so it shall be, as it is foreshowed. At these things men, that know not this art, marvel and are astonished, and they that know it, exult, and are puffed up; and by an ungodly pride departing from Thee, and failing of Thy light, they foresee a failure of the sun's light, which shall be, so long before, but see not their own, which is. For they search not religiously whence they have the wit, wherewith they search out this. And finding that Thou madest them, they give not themselves up to Thee, to preserve what Thou madest, nor sacrifice to Thee what they have made themselves; nor slay their own soaring imaginations, as fowls of the air, nor their own diving curiosities (wherewith, like the fishes of the seal they wander over the unknown paths of the abyss), nor their own luxuriousness, as beasts of the field, that Thou, Lord, a consuming fire, mayest burn up those dead cares of theirs, and re-create themselves immortally.

But they knew not the way, Thy Word, by Whom Thou madest these things which they number, and themselves who number, and the sense whereby they perceive what they number, and the understanding, out of which they number; or that of Thy wisdom there is no number. But the Only Begotten is Himself made unto us wisdom, and righteousness, and sanctification, and was numbered among us, and paid tribute unto Caesar. They knew not this way whereby to descend to Him from themselves, and by Him ascend unto Him. They knew not this way, and deemed themselves exalted amongst the stars and shining; and behold, they fell upon the earth, and their foolish heart was darkened. They discourse many things truly concerning the creature; but Truth, Artificer of the creature, they seek not piously, and therefore find Him not; or if they find Him, knowing Him to be God, they glorify Him not as God, neither are thankful, but become vain in their imaginations, and profess themselves to be wise, attributing to themselves what is Thine; and thereby with most perverse blindness, study to impute to Thee what is their own, forging lies of Thee who art the Truth, and changing the glory of uncorruptible God into an image made like corruptible man, and to birds, and four-footed beasts, and creeping things, changing Thy truth into a lie, and worshipping and serving the creature more than the Creator.

Yet many truths concerning the creature retained I from these men, and saw the reason thereof from calculations, the succession of times, and the visible testimonies of the stars; and compared them with the saying of Manichaeus, which in his frenzy he had written most largely on these subjects; but discovered not any account of the solstices, or equinoxes, or the eclipses of the greater lights, nor whatever of this sort I had learned in the books of secular philosophy. But I was commanded to believe; and yet it corresponded not with what had been established by calculations and my own sight, but was quite contrary.
