You mean in the date at the end of the Constitution? Is that what you're hanging your hat on? Every document with a date is a religious document?
Of course not. The Constitution is about religious as a roadmap or a blueprint. The Framers left the matter of religion to the State governments. I was simply replying in a sardonic way totoddhisattva's over-assertion that God isn't in the Constitution and that it is an 'atheist' document, as if it were the product of atheists. But I don't think atheists would have been caught dead dating a Constitution document "in the year of our Lord", or "ordaining" it, or referring therein to "blessings", or "Sundays excepted".
The point is that the Constitution took root in the religious/cultural/polital millieu of the time, a time in which outspoken atheists in the colonies were few and far between. The religious underpinnings of American political and legal institutions have been written about extensively by legal scholars and historians. It's just a fact that church governments, although not exclusively so, provided models for colonial civil governments and also for our constitutional system.
Cordially,
