In City of God, Augustine has entire book dedicated to his love affair with the Platonists.

From Book VIII:

Let all those philosophers, then, give place, as we have said, to the Platonists…

These philosophers, then, whom we see not undeservedly exalted above the rest in fame and glory, have seen that no material body is God, and therefore they have transcended all bodies in seeking for God. They have seen that whatever is changeable is not the most high God, and therefore they have transcended every soul and all changeable spirits in seeking the supreme. They have seen also that, in every changeable thing, the form which makes it that which it is, whatever be its mode or nature, can only be through Him who truly is, because He is unchangeable… They have understood, from this unchangeableness and this simplicity, that all things must have been made by Him, and that He could Himself have been made by none.

…whether these philosophers may be more suitably called Platonists… and the Pythagoreans… we prefer these to all other philosophers, and confess that they approach nearest to us.
