Exhortation to the Greeks 6.71

And, philosophy, hasten to bring before me not only this one man, Plato, but many others too, who proclaim the one and only true God as God by his inspiration, if they have somewhere laid hold of the truth. Antisthenes did not think this as a Cynic, but as a pupil of Socrates, when he says that “God is like no one; therefore no one can learn about him from an image.” Xenophon the Athenian would himself have written something openly about the truth, bearing witness as Socrates did, if he had not feared Socrates's poison; nonetheless he hints at it. “He who shakes all things,” he says, “and gives them rest, is manifest as someone great and mighty; but what he is like in form is not manifest. Nor does even the sun, which seems all-shining, allow itself to be seen; if anyone gazes at it shamelessly, it takes away his sight.” Where then did the son of Gryllus get his wisdom, if not plainly from the prophetess of the Hebrews, who prophesies somewhat as follows? “For what flesh can see with its eyes the heavenly and true God, the immortal, who dwells in the sky? No, human beings, born mortal, cannot even stand facing the rays of the sun.”
