If all our founding fathers were atheists, do you think we would have the freedom of religion?
I don't know if any of the founding fathers were atheists, but a lot of them were deists, and some of them even openly hated Christianity.
Thomas Paine wrote the first major work of Biblical criticism,
The Age of Reason. It's actually a clever book that he wrote in two days while in a French prison—where he wasn't allowed a Bible, so he had to quote everything from memory. It says at the beginning: "All national institutions of churches, whether Jewish, Christian or Turkish, appear to me no other than human inventions, set up to terrify and enslave mankind, and monopolize power and profit." Another quote from the book: "The whole religious complexion of the modern world is due to the absence from Jerusalem of a lunatic asylum." In a 1790 letter to a Christian friend, he
wrote, "It is from the Bible that man has learned cruelty, rapine, and murder; for the belief of a cruel God makes a cruel man." He didn't even like the morality of the New Testament, which he thought was a morality of pacifism and surrender to injustice (and most Christians seem to agree with him—how many people do you think would really "turn the other cheek" for someone who struck them, or give things to someone who tried to steal from them?).
Thomas Jefferson produced the famous
Jefferson Bible by cutting out every passage in the Gospels that mentioned miracles or the supernatural—leaving only the morality of Jesus, which
he admired. He believed Jesus was a brilliant philosopher who never claimed to be God, whose legacy was perverted by priests and the apostles (who he
called "a band of dupes and impostors"). In an 1814 letter to Horatio Spafford (who wrote
It Is Well With My Soul), he
said, "In every country and in every age, the priest has been hostile to liberty. He is always in alliance with the despot, abetting his abuses in return for protection to his own."
Benjamin Franklin deeply respected Christianity and thought religion might be necessary for public morality, but he called himself a deist. He
said in his autobiography that when he was a teenager, "Some books against deism fell into my hands. It happened that they wrought an effect on me quite contrary to what was intended by them; for the arguments of the deists, which were quoted to be refuted, appeared to me much stronger than the refutations." A month before he died, he
wrote, "As to Jesus of Nazareth, my opinion of whom you particularly desire, I think the system of morals and his religion, as he left them to us, the best the world ever saw or is likely to see; but I apprehend it has received various corrupt changes, and I have, with most of the present dissenters in England, some doubts as to his divinity; though it is a question I do not dogmatize upon, having never studied it, and I think it needless to busy myself with it now, when I expect soon an opportunity of knowing the truth with less trouble."
