Relativism and Divine Commands

It's going to be difficult to be a relativist if you think there is a God who gives binding commandments. If relativism is true, then different individuals or groups think of something as right or wrong, and if so, there is no place for saying that they are really wrong. It is just your opinion or your group's opinion against someone else's opinion. But what if someone in your moral community has the status of God? Could an adulterer say to God "Yes, you say adultery is wrong, but I don't see anything wrong with it myself. Who's to say which of us is right about adultery?" (It's too bad you are not here to hear me give this last statement with my Bill Clinton voice).
