Genesis 22 After these things God tested Abraham. He said to him, “Abraham!” And he said, “Here I am.” 2 He said, “Take your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains that I shall show you.”

If we take the translation to be faithful to the original text, then the question is not of an apparent contradiction between God's command and the moral law, but a visible contradiction between moral truths and God's command. I know that God can't do any evil. But, doesn't God's nature also make it so that he cannot command evil? And if so, how do Christians and Catholics in general resolve this?
