Lactantius

“ To understand God is difficult, to describe Him in speech is impossible, even for one to whom it is possible to understand Him; for the perfect cannot be comprehended by the imperfect, nor the invisible by the visible. ”

“ Hermes, who, on account of his virtue and his knowledge of many arts, deserved the name of Trismegistus, who preceded the philosophers in the antiquity of his doctrine, and who is reverenced by the Egyptians as a god, in asserting the majesty of the one God with infinite praises, calls Him Lord and Father, and says that He is without a name because He does not stand in need of a proper name, inasmuch as He is alone, and that He has no parents, since He exists of Himself and by Himself. ”

“ Plato asserts His monarchy, saying that there is but one God, by whom the world was prepared and completed with wonderful order. Aristotle, his disciple, admits that there is one mind which presides over the world. ”
