Greek Deism

We cannot say anything but 'God' in a sentence like that of Socrates bidding farewell to his judges: 'I go to die and you remain to live; and God alone knows which of us goes the better way.' [Plato, Dialogues, Apology.] We can use no other word even for the best moments of Marcus Aurelius: 'Can they say dear city of Cecrops, and canst thou not say dear city of God?' [The Meditations Bk. 4.] We can use no other word in that mighty line in which Virgil spoke to all who suffer with the veritable cry of a Christian before Christ: 'O you that have borne things more terrible, to this also God shall give an end.' [Aeneid Bk. 1 line 198.]
