Jefferson wasn't a fan of "faith", he was a pragmatic and practical fellow. I've never read anything that supports that he believed in a higher power. He did certainly believe that a man needed a code of ethics and morals by which to steer their life. He was a BIG fan of Jesus' teachings and philosophy but not a fan of the rest of the bible. He describes the words of Christ and the context in which they are found as being, "as easily distinguishable as diamonds in a dunghill" -high praise for Jesus, not so high of praise for the "scribes" that wrote the bible (which he calls ignorant and unlettered). He then proceeded to cut out only the parts of the new testament that were accounts of Christ and had no "mysticism" and "paste" them in to his own abridged version of the bible. That said, Jefferson was the exception not the rule. The vast majority of our "founders" were devout Christians. Jefferson was unequivocally Deist though.
