Divine command theory is one of the most controversial issues in ethics and contemporary scholars have always concerned it. In modern times, this theory has been studied in some ways, namely semantic, cognitive and ontological ones. William Ockham who has a serious attention to the free will of God and his absolute power beliefs that the source of moral values is the commandments of God and he gives us an ontological exposition of this theory. Ockham beliefs that divine commands are the necessary condition and also the sufficient condition for moral knowledge and moral values. He believes that the only criterion of right and wrong is God's will and divine law. This paper is trying to explain some different expression of divine command theory and also tries to survey Ockham's expression of this theory.
