West of Kabul, East of New York by Tamim Ansary Pg. 145-6
Are certain beliefs and behaviors good because God commands them? Or does God command them because they are good?
….If certain beliefs are good only because God commands them, it means that God might change his directives at any time. Logically its possible that justice and charity would suddenly be foul and murder good. Incest and Child Molestation might be celebrated deeds…while the moral and ethical weaklings among us would succumb to such corrupt and contemptible temptations as love, generosity and hope.
Unthinkable, you say, that God would ever promulgate such an ethos? Why not—because it wouldn’t be right? If you think that way, you’ve slipped over to the other side. You’ve assumed that right and wrong, good and bad have a status prior to God and more fundamental than He. If God cannot, from his almighty and unknowable will, enjoin murder and cruelty as virtues, God is not limitless or omnipotent.
