At a press conference in Turkey, President Obama casually rebuked the old chestnut that the United States is a Judeo-Christian nation.
"One of the great strengths of the United States," the President said, "is ... we have a very large Christian population -- we do not consider ourselves a Christian nation or a Jewish nation or a Muslim nation. We consider ourselves a nation of citizens who are bound by ideals and a set of values."

HISTORICAL NOTE:
"As the government of the United States of America is not in any sense founded on the Christian religion -- as it has in itself no character of enmity against the laws, religion or tranquillity of Mussulmen -- and as the said states never have entered into any war or act of hostility against any Mahometan nation, it is declared by the parties, that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries."

-- President John Adams' signing statement
According to Wikipedia:
"Official records show that after President John Adams sent the treaty to the Senate for ratification in May 1797, the entire treaty was read aloud on the Senate floor, and copies were printed for every Senator. A committee considered the treaty and recommended ratification, 23 of the 32 sitting Senators were present for the June 7 vote which unanimously approved the ratification recommendation...
"The Senate's ratification was only the third recorded unanimous vote of 339 taken. The treaty was printed in the Philadelphia Gazette and two New York papers, with no evidence of any public dissent."
