St Augustine, being an acclaimed teacher of Greek antiquity himself, would have read the Greats, like Plato and Aristotle.
I was rather hoping someone knew
for certain whether Augustine read Aristotle. That is, is there evidence from his writings that he read him? Oh well... I guess it IS safe to assume he did.
During the time of the Church Fathers, to which Augustine belonged, Greek philosophical thoughts were employed in Christian theology. The ideas of 'being' and 'nonbeing', material and spirit, were understood then. Augustine emphasized the attributes of God as love, omniscience, etc, over His state as nonbeing. It took the insight of St Thomas, in the Middle ages, to introduce the idea of 'Becoming', thus breaking the intellectual barrier of 'being' and 'nonbeing'. St Thomas based his insight on the Christian revelation of 'God becoming man'. Christian revelations had taken Classical metaphysics to a new height.
Exactly. The consequences of the Incarnation for our understanding of Divine Being are drastic and, we can confidently say,
infinite. Thus, Plotinus, from the point of view of Catholic theology, must be wrong. What is infinite is NOT beyond the reach of what is finite
because the twain are unified in Christ. This, as you say, seems to be the basis of the Thomistic opinion. Plato did not know the Incarnation. He MAY never have accepted the notion; he MAY never have accepted that infinity could dwell with finity. We cannot know.
Augustine, however, accepted the view of Plotinus, at least provisionally. Why? HE was certainly no stranger to the Incarnation.
