Thomas Jefferson, et. al.

Christianity neither is, nor ever was a part of the common law.

-Thomas Jefferson, letter to Dr. Thomas Cooper, February 10, 1814

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 Minerve in the brain of Jupiter. But may we hope that the dawn of reason and freedom of thought in these United States will do away with this artificial scaffolding, and restore to us the primitive and genuine doctrines of this most venerated reformer of human errors.

-Thomas Jefferson, Letter to John Adams, April 11, 1823

"[When] the [Virginia] bill for establishing religious freedom ... was finally passed, ... a singular proposition proved that its 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 word "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 its protection the Jew and the Gentile, the Christian and Mahometan, the Hindoo and infidel of every denomination."

-Thomas Jefferson, Autobiography, 1821.

"The clergy, by getting themselves established by law, and ingrafted into the machine of government, have been a very formidable engine against the civil and religious rights of man. They are still so in many countries and even in some of these United States. Even in 1783, we doubted the stability of our recent measures for reducing them to the footing of other useful callings. It now appears that our means were effectual."

-Thomas Jefferson, 1800

"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."

-James Madison, 1785

"As I have now given you my reasons for believing that the Bible is not the Word of God, that it is a falsehood, I have a right to ask you your reasons for believing the contrary; but I know you can give me none, except that you were educated to believe the Bible; and as the Turks give the same reason for believing the Koran, it is evident that education makes all the difference, and that reason and truth have nothing to do in the case. You believe in the Bible from the accident of birth, and the Turks believe in the Koran from the same accident, and each calls the other infidel. But leaving the prejudice of education out of the case, the unprejudiced truth is, that all are infidels who believe falsely of God, whether they draw their creed from the Bible, or from the Koran, from the Old Testament, or from the New.""It is often said in the Bible that God spake unto Moses, but how do you know that God spake unto Moses? Because, you will say, the Bible says so. The Koran says, that God spake unto Mahomet, do you believe that too? No. Why not? Because, you will say, you do not believe it; and so because you do, and because you don't is all the reason you can give for believing or disbelieving except that you will say that Mahomet was an impostor. And how do you know Moses was not an impostor?"

-Thomas Paine, 1797

"The government of the United States is not in any sense founded on the Christian religion."
