Gilbert Keith:
Jefferson almost sounds like a Bible thumping Christian here:
Jefferson was convinced that the teachings of Jesus were the most perfect moral framework ever constructed by man. That’s why he went to the trouble of extracting the moral lessons from the New Testament and removing them from what he saw as the unnecessary supernatural trappings of the original myth.
There aren’t a whole lot of surviving copies of the Jefferson Bible, but there’s at least one at the National Archive; they had it on display last time I was there, several years back.
Upon further reading, my earlier assertion was indeed incorrect. Although Jefferson was accused of atheism by his political opponents, his own writings mark him as a pretty much textbook deist – he believed in a Creator, but not in any particular supernatural revelation, let alone actual religion.
He is also clearly on the record as an enemy of the Church:
Letter to Dr. Benjamin Rush, September 23, 1800
“[The clergy] believe that any portion of power confided to me, will be exerted in opposition to their schemes. And they believe rightly: for I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man”
Thomas Jefferson** to Samuel Kercheval, January 19, 1810**
“But a short time elapsed after the death of the great reformer of the Jewish religion, before his principles were departed from by those who professed to be his special servants, and perverted into an engine for enslaving mankind, and aggrandizing their oppressors in Church and State.”
Letter to John Adams, April 11, 1823
“One day the dawn of reason and freedom of thought in the United States will tear down the artificial scaffolding of Christianity. And the day will come when the mystical generation of Jesus, by the Supreme Being as His father, in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter.”
Jefferson’s Autobiography
“[A]n amendment was proposed by inserting ‘Jesus Christ,’ so that [the preamble] should read ‘A departure from the plan of Jesus Christ, the holy author of our religion’; the insertion was
rejected by a great majority, in proof that they meant to comprehend, within the mantle of its protection, the Jew and the Gentile, the Christian and Mohammedan, the Hindoo and Infidel of every denomination.”
On the subject of early American founding fathers and Presidents who weren’t Christian, I’ve also found a few quotes from John Adams:
From a letter to Charles Cushing (October 19, 1756):
“Twenty times in the course of my late reading, have I been upon the point of breaking out, ‘this would be the best of all possible worlds, if there were no religion in it.’"
**Treaty of Tripoli, Article 11: **Written during the Administration of George Washington and signed into law by John Adams.
“The government of the United States is not in any sense founded on the Christian religion.”
John Adams, letter to Thomas Jefferson, (July 16, 1814):
“Cabalistic Christianity, which is Catholic Christianity, and which has prevailed for 1,500 years, has received a mortal wound, of which the monster must finally die. Yet so strong is his constitution, that he may endure for centuries before he expires.”
James Madison:
Letter to William Bradford, April 1, 1774:
“Religious bondage shackles and debilitates the mind and unfits it for every noble enterprise”
Memorial and Remonstrance Against Religious Assessments, Section 7, 1785:
“During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less, in all places, pride and indolence in the clergy; ignorance and servility in laity; in both, superstition, bigotry, and persecution.”
As for non-President founding fathers, Ben Franklin and Ethan Allen were vocal deists, and Thomas Paine an outspoken atheist. Further quotes can be provided if you want, but this post is already getting longish.
