Look - this would be easier if you would read Moore. He says that he "can't" follow the court order, because to do so would violate God's law. I say that is sophistry, because there is no Biblical command requiring his display. What Moore is really saying is that every Chief Judge who came before him, and every other judge or official who doesn't display the Ten Commandments, is in violation of God's law. It is ridiculous. In the absence of a "higher" order to leave the display, why is he not obligated to follow the civil law? One could even argue that placing this much importance on the monument, rather than on the Commandments themselves, may violate one of those very Commandments.
The real reason behind all of this is that he set up this confrontation on purpose to prolong and play out, on television, his conflict over the display of the Ten Commandments that he used to first acquire fame and power for himself.
I agree that the civil government should be a separate entity from the church. However, where we disagree is on ultimate sovereignty. You believe the State is the ultimate sovereign (right?), and our founders believed that although they are separate, both the state and the church fall under God's ultimate moral authority. The D of I makes that clear. If rights come from God, then the State that secures those rights is under God. "One nation under God..." Oops! 9th Court says no on that too!
