The Six Books of Proclus on the Theology of Plato, Volume 1

To us however discussing what pertains to every divine nature, what we assert will be known from those commonly received truths adduced in the Phædrus, and which we have before mentioned. Socrates therefore says that every thing divine is beautiful, wise, and good,[126] and he indicates that this triad pervades to all the progressions of the Gods. What therefore is the goodness, what the wisdom, and what the beauty of the Gods? With respect to the goodness of the Gods therefore, we have before observed, that it preserves and gives subsistence to the whole of things, that it every where exists as the summit, as that which fills subordinate natures, and as pre-existing in every order analogous to the first principle of the divine orders. For according to this all the Gods are conjoined with the one cause of all things, and on account of this primarily derive their subsistence as Gods. For in all beings there is not any thing more perfect than the good, and the Gods. To the most excellent of beings therefore, and which are in every respect perfect, the best and most perfect of things is adapted.
