"None of the Founding Fathers were atheists. Most of the Founders were Deists, which is to say they thought the universe had a creator, but that he does not concern himself with the daily lives of humans, and does not directly communicate with humans, either by revelation or by sacred books. They spoke often of God, (Nature's God or the God of Nature), but this was not the God of the bible. They did not deny that there was a person called Jesus, and praised him for his benevolent teachings, but they flatly denied his divinity. Some people speculate that if Charles Darwin had lived a century earlier, the Founding Fathers would have had a basis for accepting naturalistic origins of life, and they would have been atheists. Most of them were stoutly opposed to the bible, and the teachings of Christianity in particular."

"...Because of the rural nature of early America, many in colonial times chose churches based on convenience. Where they went to church regularly may not be a perfect indicator of what faith they considered themselves. Thomas Jefferson, for example, was raised Episcopalian, donated a significant amount of money to building Episcopalian churches, attended a Episcopalian church, and yet is not considered an orthodox Episcopalian by any historian of note. His views would be considered heretical by today's orthodox standards."

FYI, this is not a left-wing conspiracy. Yes, they belonged to some sort of a denomination. If you had read any links I posted for you, you would have understood that while they may have attended church or claimed a denomination, they were NOT religious.

These were smart men and were not so weak-minded as to be swayed by some dude in a robe asking them for their money.
