Phill presumably believes in Divine Command theory. But its not really obvious why "Divine command theory" really solves the problem. For example consider the following passage: “This is what the LORD Almighty says: 'I will punish the Amalekites for what they did to Israel when they waylaid them as they came up from Egypt. Now go, attack the Amalekites and totally destroy everything that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys." - Imagine Phill was an Amalekite. Then the murder of his whole family would be morally righteous?
