Augustine, Confessions, book VII:
And Thou, willing first to show me how Thou resistest the proud, but givest grace unto the humble, and by how great an act of Thy mercy Thou hadst traced out to men the way of humility, in that Thy Word was made flesh, and dwelt among men:- Thou procuredst for me, by means of one puffed up with most unnatural pride, certain books of the Platonists, translated from Greek into Latin. And therein I read, not indeed in the very words, but to the very same purpose, enforced by many and divers reasons, that In the beginning was the Word, and the Word was with God, and the Word was God: the Same was in the beginning with God: all things were made by Him, and without Him was nothing made: that which was made by Him is life, and the life was the light of men, and the light shineth in the darkness, and the darkness comprehended it not. And that the soul of man, though it bears witness to the light, yet itself is not that light; but the Word of God, being God, is that true light that lighteth every man that cometh into the world. And that He was in the world, and the world was made by Him, and the world knew Him not. But, that He came unto His own, and His own received Him not; but as many as received Him, to them gave He power to become the sons of God, as many as believed in His name; this I read not there.
Again I read there, that God the Word was born not of flesh nor of blood, nor of the will of man, nor of the will of the flesh, but of God. But that the Word was made flesh, and dwelt among us, I read not there. For I traced in those books that it was many and divers ways said, that the Son was in the form of the Father, and thought it not robbery to be equal with God, for that naturally He was the Same Substance. But that He emptied Himself, taking the form of a servant, being made in the likeness of men, and found in fashion as a man, humbled Himself, and became obedient unto death, and that the death of the cross: wherefore God exalted Him from the dead, and gave Him a name above every name, that at the name of Jesus every knee should how, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father; those books have not. For that before all times and above all times Thy Only-Begotten Son remaineth unchangeable, co-eternal with Thee, and that of His fulness souls receive, that they may be blessed; and that by participation of wisdom abiding in them, they are renewed, so as to be wise, is there. But that in due time He died for the ungodly; and that Thou sparedst not Thine Only Son, but deliveredst Him for us all, is not there. For Thou hiddest these things from the wise, and revealedst them to babes; that they that labour and are heavy laden might come unto Him, and He refresh them, because He is meek and lowly in heart; and the meek He directeth in judgment, and the gentle He teacheth His ways, beholding our lowliness and trouble, and forgiving all our sins. But such as are lifted up in the lofty walk of some would-be sublimer learning, hear not Him, saying, Learn of Me, for I am meek and lowly in heart, and ye shall find rest to your souls. Although they knew God, yet they glorify Him not as God, nor are thankful, but wax vain in their thoughts; and their foolish heart is darkened; professing that they were wise, they became fools.
And therefore did I read there also, that they had changed the glory of Thy incorruptible nature into idols and divers shapes, into the likeness of the image of corruptible man, and birds, and beasts, and creeping things; namely, into that Egyptian food for which Esau lost his birthright, for that Thy first-born people worshipped the head of a four-footed beast instead of Thee; turning in heart back towards Egypt; and bowing Thy image, their own soul, before the image of a calf that eateth hay. These things found I here, but I fed not on them. For it pleased Thee, O Lord, to take away the reproach of diminution from Jacob, that the elder should serve the younger: and Thou calledst the Gentiles into Thine inheritance. And I had come to Thee from among the Gentiles; and I set my mind upon the gold which Thou willedst Thy people to take from Egypt, seeing Thine it was, wheresoever it were. And to the Athenians Thou saidst by Thy Apostle, that in Thee we live, move, and have our being, as one of their own poets had said. And verily these books came from thence. But I set not my mind on the idols of Egypt, whom they served with Thy gold, who changed the truth of God into a lie, and worshipped and served the creature more than the Creator.
