The Divine Command Theory is the view that morality is somehow dependent upon God, and that moral obligation consists in obedience to God’s commands. The Divine Command Theory includes the claim that morality is ultimately based on the commands or character of God, and that the morally right action is the one that God commands or requires. The specific content of these divine commands varies according to the particular religion and the particular views of the individual divine command theorist, but all versions of the theory hold in common the claim that morality and moral obligations ultimately depend on God.
The dilemma is this : is what is morally good commanded by God because it is morally good, or is it morally good because it is commanded by God?
Socrates dealt with this dilemma. He asked whether God loves pious people because they are pious, or whether the pious are pious only because they are loved by the God. Socrates and Euthyphro both accept the first option: that God loved pious people because they are pious.
But this however means, according to Socrates, that we are forced to reject the second option: that the pious are pious only because they are loved by the God. So the pious are cannot be said to be pious because they are loved by God.
This means that just because God’s love for one does not make one any better an individual. So God’s love for you does not help to explain why someone who is pious is the pious.
Socrates points out that if both options were true, they together would yield a vicious circle, with the gods loving the pious because they are pious, and the pious being pious because God loves them.
And this would in turn mean, Socrates argues, that the pious are not the same as the god-beloved, for what makes the pious the pious is not what makes the god-beloved the god-beloved. After all, what makes the god-beloved the god-beloved is the fact that the gods love them, whereas what makes the pious the pious is something else.
