"Mingling religion with politics may be disavowed and reprobated by every inhabitant of America...All national institutions of churches, whether Jewish, Christian, or Turkish (Muslim), appear to me no other than human inventions set up to terrify and enslave mankind, and monopolize power and profit."
-Thomas Payne
“Of all the systems of religion that ever were invented, there is no more derogatory..., more unedifying to man, more repugnant to reason, and more contradictory to itself than this thing called Christianity. Too absurd for belief, too impossible to convince, and too inconsistent for practice, it renders the heart torpid or produces only atheists or fanatics. As an engine of power, it serves the purpose of despotism, and as a means of wealth, the avarice of priests, but so far as respects the good of man in general it leads to nothing here or hereafter.”
― Thomas Paine, The Age of Reason
"'The government of the United States of America is not in any sense founded on the Christian Religion"
-John Adams
"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.
"They [the Christian 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. But this is all they have to fear from me: and enough, too, in their opinion."
-Thomas Jefferson to Dr. Benjamin Rush, Sept. 23, 1800
"The United States of America have exhibited, perhaps, the first example of governments erected on the simple principles of nature: and if men are now sufficiently enlightened to disabuse themselves of artifice, imposture, hypocrisy, and superstition, they will consider this event as an era in their history... [T]he detail of the formation of the American governments... may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had any interviews with the gods, or were in any degree under the inspiration of heaven... it will for ever be acknowledged that these governments were contrived merely by the use of reason and the senses... Thirteen governments thus founded on the natural authority of the people alone, without a pretence of miracle or mystery, which are destined to spread over the northern part of that whole quarter of the globe, are a great point gained in favour of the rights of mankind.”
― John Adams, The Political Writings of John Adams, [A Defence of the Constitutions of the United States of America, 1787]
