Please read more about what Jefferson had to say about what he thought of the Christian faith. Read Jefferson's own words, not other people's bizarre interpretations, backed up by misquotes taken out of context.

Are we misunderstanding the entirety of the quote?

"I am a real Christian, that is to say, a disciple of the doctrines of Jesus, very different from the Platonists, who call me infidel and themselves Christians and preachers of the gospel, while they draw all their characteristic dogmas from what its author never said nor saw. They have compounded from the heathen mysteries a system beyond the comprehension of man, of which the great reformer of the vicious ethics of deism of the Jews, were he to return on earth, would not recognize one feature." — Thomas Jefferson

Jefferson was a rationalist. He described himself as a Deist (in the classic liberal sense) or a Unitarian. He wrote many times that trinitarian Christianity was a form of insanity and a perversion of the original teachings of Jesus.

I've always found that when one person passes judgment against someone else, the person passing the judgment is always guilty of the crime themselves. You have provided me no reason to believe that you are an exception to this rule, MACATAC. You have only given me one more reason to believe what I already know.

Have you never read this:

"Judge not, that ye be not judged. For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye."

Do you not comprehend what that guy was saying either?

I am a real Christian, that is to say, a disciple of the doctrines of Jesus.

Thomas Jefferson, The Writings of Thomas Jefferson, Albert Ellery Bergh, editor(Washington, D. C.: The Thomas Jefferson Memorial Association, 1904), Vol. XIV, p. 385,to Charles Thompson on January 9, 1816.

"2. The revealed or divine laws of the Scriptures. In this statement he points out that the revealed laws as found in the Bible are really a part of the laws of nature. "This law of nature, dictated by God himself, is of course superior in obligation to any other. No human laws are of any validity, if contrary to this. The revealed or divine law found only in the Holy Scriptures are found upon comparison to be really part of the original law of nature." It seems astounding that these words come from the premier law book of the 18th, 19th and early 20th

centuries. In Blackstone's law book, when the human law was cited, it also cited the Biblical reference upon which that law was built."

The author makes other statements that throw a lot of doubt on his credibility, but Blackstone might be a clue.

American Heritage has an interesting article that I should dig into:
http://www.americanheritage.com/articles/magazine…
It doesn't mention the phrase "Nature's God" but it does discuss some of Jefferson's religious philosophy.

Sullivan County has something interesting to say:

Sullivan County points to Blackstone also as the origin of the phrase.

Blackstone considered the Laws of Nature's God to be divine law. Jefferson compared the teachings of Jesus to the teachings of Socrates. He believed that the written Bible was a flawed document; that the original Jesus was a rabbi or guru and that the stories of miracles were great exaggerations. Where Blackstone says "The doctrines thus delivered we call the revealed or divine law, and they are to be found only in the holy scriptures" Jefferson did not believe in the divinity of scripture. He found only a sublime philosophy in the pages of the Bible.
