It has always been crystal clear to me that my civil rights in this society (and in any society) were something of human invention. They may have reflected a divine will to some extent, they may have consciously attempted to emulate it, they may have (as in the case of your Constitution) given some official recognition to it, but they are of human invention.

God did not write down your Constitution on a piece of paper. A bunch of men did, and they chose to speak of God when they did so. Many other civil codes have been written in that spirit by men who chose to speak of God when they wrote them. Not all of them were codes I'd want to live under.
