This is a little old now but worth mentioning in light of the new atheist desperation for grounding morality in something other than thin air:
JWM: Take the humanist view, that all you need are human values. Well, if law and human rights are simply developed by human beings, in their own cultures, what do you we do with the Third Reich, where law and the concept of values is damnable, is racist? They sent Jews and other prisoners to gas ovens and the like. The only way you get proper human rights is to align them with inalienable rights. But ‘inalienable’ means ‘absolute.’ Since water doesn’t rise above its own level, you’re never going to get absolute values from a non-absolute source. You’ve got to have an absolute source. That means God Almighty. That means a God who has loved us and revealed Himself to us and told us what absolute values are.
PHC: Would they agree with that premise, that there are absolute values?
JWM: They’re caught, aren’t they? They can’t really well say that the Nazi regime is just another way of looking at things. On the other hand, there’s no way that they can arrive at absolute values from human opinion. So they’re stuck.
JWM is of course John Warrick Mongomery, a man with more degrees than I have fingers.
Dr. John Warwick Montgomery holds ten earned degrees, including three earned doctorates in History, Theology, and Law, is an ordained Lutheran minister and English barrister, and is admitted to practice as a lawyer before the Supreme Court of the United States. Author of more than fifty books in four languages, he has won leading religious liberties cases before the European Court of Human Rights, Strasbourg, France.
