“The government of the United States is not, in any sense, founded on the Christian religion.” — John Adams (Treaty of Tripoli, article 11)

“Every new and successful example, therefore, of a perfect separation between the ecclesiastical and civil matters, is of importance; and I have no doubt that every new example will succeed, as every past one has done, in showing that religion and Government will both exist in greater purity the less they are mixed together.” — James Madison (Letter to Edward Livingston, July 10, 1822)

“I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should “make no law respecting an establishment of religion, or prohibiting the free exercise thereof,” thus building a wall of separation between Church and State.” — Thomas Jefferson (letter to a Committee of the Danbury Baptist Association, Connecticut, January 1, 1802)

“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.” — Thomas Jefferson (Letter to John Adams, April 11, 1823)

“There is no position on which people are so immovable as their religious beliefs. There is no more powerful ally one can claim in a debate than Jesus Christ, or God, or Allah, or whatever one calls this supreme being. But like any powerful weapon, the use of god’s name on one’s behalf should be used sparingly. The religious factions that are growing throughout our land are not using their religious clout with wisdom. They are trying to force government leaders into following their position 100 percent. If you disagree with these religious groups on a particular moral issue, they complain, they threaten you with a loss of money or votes or both.
I’m frankly sick and tired of the political preachers across this country telling me as a citizen that if I want to be a moral person, I must believe in ‘A,’ ‘B,’ ‘C,’ and ‘D.’ Just who do they think they are? And from where do they presume to claim the right to dictate their moral beliefs to me?” — Barry Goldwater (US Senator AZ, Republican Candidate for President 1964, Godfather of modern Conservative movement)
