You're asking a question that assumes there is a moral standard independent of God - assuming that God exists - and then simply stating that there must be one because "God can only act in a moral way", something you ALSO simply asserted.
If you read carefully, I think you'll see that I did not assume there is an independent moral standard. I gave two possibilities. I did mention god's actions but it would perhaps since I am referring directly to the affect on humanity to refer to god's commands to humanity. The possibilities restated are:
1) God's commands are moral judged against a standard independent of his existence- an objective standard outside of god. Or...
2) God's commands are moral by definition. God's commands are moral because they are god's actions.
If you are willing to concede god can give immoral commands, then this argument isn't really applicable, since the concession that god may give immoral commands denies religious argument that objective morality can only come from god. There is no reason to trust god if it is possible his commands are immoral.
Once again, you're assuming a strictly human perspective, and then trying to jam God into it. AND you are still confusing "objective" with "outside of oneself" in relation to God.
If you think about it, your number two is a bit closer to the truth. "Moral" simply means "conforming to a standard of right and wrong". If God is that standard of right and wrong, then He is morality by definition.
Which brings us back to my confusion as to why you're asking the question in the first place.
Which still doesn't make the way you're using them correct.
Actually, there's a lot of doubt about that statement. While there is a great deal of debate about how to apply morality to certain situations, it's striking how little disagreement there really is about the nature of morality itself. Take welfare payments as an example. The argument is essentially about what is the best and most effective way to help people who are poor get back on their feet. The argument is NEVER about whether or not it's moral to do so. That is simply understood and accepted.
Use your head. If God exists, then by definition HE is the moral standard against which actions are judged. How can you judge God immoral against Himself? (This is assuming that you're silly and hubristic enough to try to judge God at all.)
Again, use your head. WHY do you think rape and murder are immoral? Because God said they were (in this hypothetical where God exists, for those of you getting your atheistic panties in a ruffle out there). You're positing a situation where God contradicts His own nature and you then judge Him by applying His own moral standard to Him as a superior moral force yourself.
You're going to make yourself trying to be Mr. Clever with all this pointless circular logic.
Not quite. The argument is that religion expresses an objective morality, established by the Creator of the Universe as part of the integral fabric of that creation, and that any attempt to replace that with a different morality based in human perception is, by definition, subjective because it only applies to the person who holds that perspective.
More like equally invalid at the point where they diverge from objective morality.
Not quite. Moral relativism is where you try to make excuses why THIS situation shouldn't have the objective moral standard applied to it. Objectively, we all believe that killing innocent human beings is immoral. Moral relativism is trying to come up with reasons why it's okay to do so THIS time.
If you assume that God exists, then yes. The moral standard they are presenting is, by definition, objective and ultimate.
Except that that assumes that God exists but is really just like another human. You can't posit God's existence and then immediately negate it and expect to have any kind of logical discussion. Pick one.
Okay, you're doing it again. God is not a human, so please stop attributing human traits to Him willy-nilly, like changing His mind about morals on a whim. He is either God, or He isn't. Pick one.
So the moral standards dictated by religion are both subjective to the capricious whims of god and the subjective interpretations of adherents, thus making them at least as subjective and in effect relativistic as the morals of non-believers.
Sounds to me like what you really want to argue is that you're not obligated to be moral. If that's the case, then just go be immoral and stop wasting time trying to justify it.
In essence, when religious people say there really is no reason why a non-believer should not feel it is perfectly acceptable to rape and murder, by the same logic there is no reason why a religious person should not feel it is perfectly acceptable to rape and murder- if the religious person's interpretation is such that he feels like god commands it.
Well, thank you SO MUCH for so neatly summing up exactly what you haven't bothered to understand about Christians.
Seriously, why do you people insist on coming in here and positing threads based on stating your misconceptions as fact? Did it ever occur to you that before asking if God is moral, you should try actually asking what Christians believe about God and morality, instead of just assuming you know and running off half-cocked?
