Abstract: The morally good action is the overall good action, one that there is overriding reason to do. Morally, good actions include both obligatory actions and supererogatory good actions. There are three propositions stating which actions are good and which are bad. Some moral truths do not depend for their truth on the will of God. But, because he is our supreme benefactor, he has the right to command us to do many actions; and his comment makes those actions obligatory (and his commendations of them makes actions supererogatarily good).
