No, I rely solely on you Libertarians for my knowledge of the Founding Fathers.
Sarcasm aside:
What would you call someone who appeals for prayer at the Constitutional Convention, an atheist?
A politician. But who knows what Franklin believed by the end of it. There's a lot of discussion about it. He was unquestionably a deist for some time, but there's reason to suspect that changed toward the end of his life. Then there's this:
"You desire to know something of my religion. It is the first time I have been questioned upon it. But I cannot take your curiosity amiss, and shall endeavour in a few words to gratify it. Here is my creed. I believe in one God, Creator of the Universe. That He governs it by His providence. That He ought to be worshipped. That the most acceptable service we render Him is doing good to His other children. That the soul of man is immortal, and will be treated with justice in another life respecting its conduct in this. These I take to be the fundamental principles of all sound religion, and I regard them as you do in whatever sect I meet with them.
"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 think it needless to busy myself with it, when I expect soon an opportunity of knowing the Truth with less trouble. I see no harm, however, in its being believed, if that belief has the good consequence, as probably it has, of making his doctrines more respected and better observed; especially as I do not perceive that the Supreme takes it amiss, by distinguishing the unbelievers in His government of the world with any particular marks of His displeasure.
"I shall only add, respecting myself, that, having experienced the goodness of that Being in conducting me prosperously through a long life, I have no doubt of its continuance in the next, without the smallest conceit of meriting it... I confide that you will not expose me to criticism and censure by publishing any part of this communication to you. I have ever let others enjoy their religious sentiments, without reflecting on them for those that appeared to me unsupportable and even absurd. All sects here, and we have a great variety, have experienced my good will in assisting them with subscriptions for building their new places of worship; and, as I never opposed any of their doctrines, I hope to go out of the world in peace with them all."
