Yep, many were Deists. And, while progressive, the founding fathers argued vigorously over slavery, which was on its way out in the western world. Ultimately, they conceded to the southern states and allowed it to remain law in the country. In some circles, one might use another word for "conceded"... "Compromised". It's not like slavery was the gold standard in 1787. Western countries were moving away from it pretty solidly. It was already out of England and abolitionist movements were actively petitioning its removal from the rest of the Empire. Many Christian churches were vigorously stumping against it, saying it was un-Christian (which it obviously is). France had mostly eliminated it a century prior to the founding of the USA and wiped it out of the empire entirely just five years after the ratification of the Constitution. So the "hand of god" thing doesn't fly with me. Again, it's ignorant of what was actually happening around the world and the trends that were already in play, trends the founding fathers ignored (at least in part) to appease southern states and get the damned Constitution ratified. And because of that compromise, America was one of the last western nations to abolish slavery and it required the bloodiest war in our history to get rid of it. So, no, god's hand was not involved in that thing because if it was, such colossal injustice and bloodshed would not have occurred because it didn't have to occur. The two most influential countries, England and France, were well on the way to abolishing it when the USA was formed. It didn't have to be that way, yet it was.
