Wow, that's the first I've heard this argument. But, let's see what John Adams had to say about that:<quoted text>Read slowly. OUR county was FOUNDED on religious PRINCIPALS.principals get it??? I didn't think so.
principal (ˈprɪns& #618;p ə l)
1. first in importance, rank, value, etc; chief
The United States of America have exhibited, perhaps, the first example of governments erected on the simple principles of nature; and if men are now sufficiently enlightened to disabuse themselves of artifice, imposture, hypocrisy, and superstition, they will consider this event as an era in their history. Although the detail of the formation of the American governments is at present little known or regarded either in Europe or in America, it may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had interviews with the gods, or were in any degree under the influence of Heaven, more than those at work upon ships or houses, or laboring in merchandise or agriculture; it will forever be acknowledged that these governments were contrived merely by the use of reason and the senses.
So, I think I know what you mean by religious "principals" but it would seem that even if the men in charge were all solid Christians they didn't bother conferring with their god during the creation of the country. They used reason, not religious influence.
