[PaulJ]

But that morality of the unchanging God is interprted by human beings; hence the ever changing moral codes we humans have lived by.

[DittoJed2]

But the morality in and of itself, coming from God, is not subjective. God didn't look and decide. That morality emanated from who He was. If we, as humans recognize it, obey it, understand it, ignore it, whatever, doesn't change the fact that it is an objective moral standard. It just is. A non-theistic moral standard can never make the same claim to objectivity because by definition, for the atheist, human beings are all there is. One human's standards have no more weight than another. Therefore, what is immoral in America may be moral in Saudi Arabia. Subjectivity. At least, in Christianity, there is a solidified document to which one can refer and say this is moral this is immoral. Doesn't mean that we do it, but it is there.
