i need to cite American history?
Page 41 in Jefferson's autobiography called the "Autobiography of Thomas Jefferson". Written in 1821.
"The bill for establishing religious freedom, the principles of which had, to a certain degree, been enacted before, I had drawn in all the latitude of reason & right. it still met with opposition; but, with some mutilations in the preamble, it was finally past; and a singular proposition proved that it’s protection of opinion was meant to be universal. where the preamble declares that coercion is a departure from the plan of the holy author of our religion, an amendment was proposed, by inserting the words ‘Jesus Christ’ so that it 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 it’s protection, the Jew and the Gentile, the Christian and Mahometan, the Hindoo and infidel of every denomination."
Yall have to remember this was post Reformation and Renaissance. The founders got their ideas from enlightenment thinkers who were not huge fans of Christianity due to the divine right of kings and their use of Jesus Christ to oppress the people. (that was king George's justification for what he was doing). They believed in God, but doubt most were Christians due to the landscape at the time.
