The hypothetical I presented assumes for argument that God does exist. But God existing is completely different from whether God is worthy of obedience.
I hold that the two are not completely different. One of God's attributes, to me, is that He is worthy of obedience. He cannot exist without that attribute. My belief in that is probably what caused our trouble. I should have stated it in my first post, and you could have told me that you did not intend for it be included.
My intention of the hypothetical was to query just how far people will go when it comes to obeying God. A lot of theists talk with great conviction about how moral God is and how superior a world view that entrenches morality on his existence is. They say that it derives from God, that his existence somehow objectifies and codifies morality to a binary black and white standard.
I believe that is a position that one cannot hold without first believing in God. To hypothetically suppose that God exists while restricting His qualities to only those that suit you is, I believe, to build the hypothetical to specifically negate the possibility that the theist is correct. I believe you would have to build the hypothetical with God possessing the qualities that the theists believe Him to possess.
So it must be asked of course: Does that mean you'd literally do anything for God? Does that mean you'd literally follow any order, no matter how obscene or atrocious it might appear to be?
You are assuming that any of it would appear obscene or atrocious. I highly doubt that it would. If God was known to exist and if God went about commanding the killing of people, there is no reason to assume that it would appear immoral. I want to believe that I would follow any order God gives, but with the orders He has already given (those I believe in), I fail to obey all the time. So the answer is, no. I would probably fail under those circumstances too.
If you really would then it would have to be asked what you think morality is because it would have almost no resemblance or relevance to concern and compassion towards humanity but only concern with God, and would thus be a glorified slave-master relationship.
I believe you have settled on "a glorified slave-master relationship" as your personal catch phrase for the topic without giving too much thought to what you are talking about. It has nothing to do with a slave's relationship to a master, because as a Christian, I can walk away anytime. God does not hold me captive, because I do not serve Him out of fear of punishment. I serve out of love and respect.
If you want to analogize, it is similar to a parent-child relationship. In fact, it is a parent-child relationship. He is my Father, and I am His child. I do what He says because He knows more than me. What He says is right because He says it is right. He understands what I do not.
I do not understand a morality apart from God. When I was without belief, I found no reason to think in moral terms, because the only good things were those things that benefited me. It was entirely subjective. So to me, morality is fundamentally tied to God. Without God, morality does not exist, at least not in an objective sense.
