Abstract
I'm not going to discuss whether or not there is a God, but simply whether if there is a God, that makes any difference to morality. I shall argue first that the existence and actions of God would make no difference to the fact that there are moral truths—and on this you may already agree with me. But I shall go on to argue that the existence and actions of God would make a great difference to the content of morality, to the seriousness of morality, and our knowledge of morality—and on all that I may need to convince you. I assume a standard Western account of the nature of God, as essentially eternal, omnipotent, omniscient, perfectly good, creator and sustainer of the universe and all that it contains, the kind of God affirmed by Christianity, Judaism, and Islam as well as some other religions.
