When we assume God to be a guiding principle well, sure enough, a god is usually characteristic of a certain system of thought or morality. For instance, take the Christian God, the summum bonum: God is love, love being the highest moral principle; and God is spirit, the spirit being the supreme idea of meaning. All our Christian moral concepts derive from such assumptions, and the supreme essence of all of them is what we call God.
