Thomas Jefferson certainly had a strong faith in God, though not in the doctrines of the man-made religions. He was more open about this in the later stages of his life:To Thomas Paine: Dear Sir, --Your favour of September 11, was duly received. It is with great delight to hear of you coming our way. May I say with all frankness, Mr. Paine, that you should take my advice and express nothing publicly regarding your religion. The people aren't ready for your views. Trust me, the time is not right and you'll be a much happier person. Do as I have done. Since religion is "solely between man and his God," even those closest to me never knew exactly what I believed.
An enigmatic and enlightened individual -- no doubt about that. :)I have examined all the known superstitions of the world, and I do not find in our particular superstition of Christianity one redeeming feature. They are all alike founded on fables and mythology.
