Update: All that Christians profess regarding this country...
... Is wrong.
Juan Cole had this to say:
I am a student of history, but this one has, until now, escaped me. I will forever more, pull this quote out any time I hear some Christian nut claim that our country is a Christian Nation.
The US Senate, full of founding fathers, and the Adams government, approved the Treaty with Tripoli (now Libya) of 1797, which included this language:"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 Musselmen; and as the said States never have entered into any war or act of hostility against any Mehomitan 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."
The treaty is important for showing the mindset of the fashioners of the American system.
