Theism is a modern word, meaning belief in God. But there is no unanimity about the attributes of God. The Greek theos meant a superhuman and in particular an immortal Being. For the Platonists he was a “Soul,” and there may be more than one soul. The Christian Fathers—Augustine as well as the Greeks, could say without reproach that God became man in order that man might become divine. The Logos in the Fourth Gospel is God, but not the Godhead. “My Father is greater than I.”
