In his Confessions, Augustine writes that he studied Platonism before converting to Christianity. Of all philosophies, Platonism most approximates Christianity, so the former serves to prepare his mind for the latter. But perhaps more importantly, familiarity with both enables him to discern the preeminence of Christianity over philosophy.
Augustine devotes the last three books of Part I of City of God, Books VIII to X, to a discussion of Platonism. He explains the agreements and disagreements between Christianity and Platonism, and engages with Platonist philosophers, namely, Apuleius and Porphyry, whose doctrines either indirectly or directly contradicts Christianity.
In Defence of Incarnation
What is there incredible, I say, in the assertion that God assumed a human soul and body? You yourselves ascribe such excellence to the intellectual soul, which is, after all, the human soul, that you maintain that it can become consubstantial with that intelligence of the Father whom you believe in as the Son of God. What incredible thing is it, then, if some one soul be assumed by Him in an ineffable and unique manner for the salvation of many? Moreover, our nature itself testifies that a man is incomplete unless a body be united with the soul. This certainly would be more incredible, were it not of all things the most common; for we should more easily believe in a union between spirit and spirit, … even though the one were human, the other divine, the one changeable and the other unchangeable, than in a union between the corporeal and the incorporeal.
But perhaps it is the unprecedented birth of a body from a virgin that staggers you? But, so far from this being a difficulty, it ought rather to assist you to receive our religion, that a miraculous person was born miraculously. Or, do you find a difficulty in the fact that, after His body had been given up to death, and had been changed into a higher kind of body by resurrection, and was now no longer mortal but incorruptible, He carried it up into heavenly places?
[Porphyry] frequently teaches that a body of every kind is to be escaped from, in order that the soul may dwell in blessedness with God. But here, in place of following Porphyry, you ought rather to have corrected him. … For, as scholars of Plato, you hold that the world is an animal, and a very happy animal, which you wish to be also everlasting. How, then, is it never to be loosed from a body, and yet never lose its happiness, if, in order to the happiness of the soul, the body must be left behind.
Against Reincarnation
This found no favor with Porphyry, and very justly; for it is indeed foolish to believe that souls should desire to return from that life, which cannot be very blessed unless by the assurance of its permanence, and to come back into this life, and to the pollution of corruptible bodies, as if the result of perfect purification were only to make defilement desirable. For if perfect purification effects the oblivion of all evils, and the oblivion of evils creates a desire for a body in which the soul may again be entangled with evils, then the supreme felicity will be the cause of infelicity, and the perfection of wisdom the cause of foolishness, and the purest cleansing the cause of defilement.
And, however long the blessedness of the soul last, it cannot be founded on truth, if, in order to be blessed, it must be deceived. For it cannot be blessed unless it be free from fear. But, to be free from fear, it must be under the false impression that it shall be always blessed,—the false impression, for it is destined to be also at some time miserable. How, then, shall the soul rejoice in truth, whose joy is founded on falsehood? Porphyry saw this, and therefore said that the purified soul returns to the Father, that it may never more be entangled in the polluting contact with evil.
The Transcendence of God
We worship that God who has appointed to the natures created by Him both the beginnings and the end of their existing and moving; who holds, knows, and disposes the causes of things; … He who is wholly everywhere, included in no space, bound by no chains, mutable in no part of His being, filling heaven and earth with omnipresent power, not with a needy nature. Therefore He governs all things in such a manner as to allow them to perform and exercise their own proper movements. For although they can be nothing without Him, they are not what He is. He does also many things through angels; but only from Himself does He beatify angels. So also, though He send angels to men for certain purposes, He does not for all that beatify men by the good inherent in the angels, but by Himself, as He does the angels themselves.
