"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 the laity, in both, superstition, bigotry and persecution...In some instances they have been seen to erect a spiritual tyranny on the ruins of the Civil authority; in many instances they have been seen upholding the thrones of political tyranny: in no instance have they been seen the guardians of the liberties of the people. "
-James Madison
"The experience of the United States is a happy disproof of the error so long rooted in the unenlightened minds of well-meaning Christians, as well as in the corrupt hearts of persecuting usurpers, that without a legal incorporation of religious and civil polity, neither could be supported. A mutual independence is found most friendly to practical Religion, to social harmony, and to political prosperity"
-James Madison
"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
"The Government of the United States of America is not, in any sense, founded on the Christian religion... It is no more a Christian nation than it is a Jewish or Mohametan (Muslim) one."
_John Adams
"But it does me no injury for my neighbor to say there are twenty gods or no God. It neither picks my pocket nor breaks my leg. "
-Thomas Jefferson
"History, I believe, furnishes no example of a priest-ridden people maintaining a free civil government. This marks the lowest grade of ignorance of which their civil as well as religious leaders will always avail themselves for their own purposes."
-Thomas Jefferson to Alexander von Humboldt, Dec. 6, 1813.
"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... "
-Thomas Jefferson
"All national institutions of churches, whether Jewish, Christian, or Turkish, appear to me no other than human inventions set up to terrify and enslave mankind, and monopolize power and profit.”

“It is from the Bible that man has learned cruelty, rapine, and murder; for the belief of a cruel God makes a cruel man.”
