America is not a christian nation.
If I could conceive that the general government might ever be so administered as to render the liberty of conscience insecure, I beg you will be persuaded, that no one would be more zealous than myself to establish effectual barriers against the horrors of spiritual tyranny, and every species of religious persecution.” ~Founding Father George Washington, letter to the United Baptist Chamber of Virginia, May 1789 “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. Although the detail of the formation of the American governments is at present little known or regarded either in Europe or in America, it may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had interviews with the gods, or were in any degree under the influence of Heaven, more than those at work upon ships or houses, or laboring in merchandise or agriculture; it will forever be acknowledged that these governments were contrived merely by the use of reason and the senses.” ~John Adams, “A Defence of the Constitutions of Government of the United States of America” 1787-1788
“The Government of the United States of America is not in any sense founded on the Christian religion.” ~1797 Treaty of Tripoli signed by Founding Father John Adams
“In every country and in every age, the priest has been hostile to liberty. He is always in alliance with the despot, abetting his abuses in return for protection to his own. It is error alone that needs the support of government. Truth can stand by itself.” ~Founding Father Thomas Jefferson, in a letter to Horatio Spofford, 1814
