Nicene and Post-Nicene Fathers, Vol. II:
City of God: Chapter 12

Chapter 12.—That Even the Platonists, Though They Say These Things Concerning the One True God, Nevertheless Thought that Sacred Rites Were to Be Performed in Honor of Many Gods.

But we need not determine from what source he learned these things,—whether it was from the books of the ancients who preceded him, or, as is more likely, from the words of the apostle:  “Because that which is known of God, has been manifested among them, for God hath manifested it to them.  For His invisible things from the creation of the world are clearly seen, being understood by those things which have been made, also His eternal power and Godhead.” 311   From whatever source he may have derived this knowledge, then, I think I have made it sufficiently plain that I have not chosen the Platonic philosophers undeservedly as the parties with whom to discuss; because the question we have just taken up concerns the natural theology,—the question, namely, whether sacred rites are to be performed to one God, or to many, for the sake of the happiness which is to be after death.  I have specially chosen them because their juster thoughts concerning the one God who made heaven and earth, have made them illustrious among philosophers.  This has given them such superiority to all others in the judgment of posterity, that, though Aristotle, the disciple of Plato, a man of eminent abilities, inferior in eloquence to Plato, yet far superior to many in that respect, had founded the Peripatetic sect,—so called because they were in the habit of walking about during their disputations,—and though he had, through the greatness of his fame, gathered very many disciples into his school, even during the life of his master; and though Plato at his death was succeeded in his school, which was called the Academy, by Speusippus, his sister’s son, and Xenocrates, his beloved disciple, who, together with their successors, were called from this name of the school, Academics; nevertheless the most illustrious recent philosophers, who have chosen to follow Plato, have been unwilling to be called Peripatetics, or Academics, but have preferred the name of Platonists.  Among these were the renowned Plotinus, Iamblichus, and Porphyry, who were Greeks, and the African Apuleius, who was learned both in the Greek and Latin tongues.  All these, however, and the rest who were of the same school, and also Plato himself, thought that sacred rites ought to be performed in honor of many gods.
