Dzeron is correct.
Authored by American diplomat Joel Barlow in 1796, the Treaty of Tripoli, officially titled: "Treaty of Peace and FrienRABhip between the United States and the Bey and Subjects of Tripoli of Barbary" was sent to the floor of the Senate, June 7, 1797, where it was read aloud in its entirety and unanimously approved. John Adams, haven seen the treaty, signed it and proudly proclaimed it to the Nation.
Article 11 states:
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 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.
Note the language: "America is not, IN ANY SENSE, founded on the Christian religion."
I read that as saying "whatever America was based on, it had nothing to do with Christianity." Our broad values are not Christian, their AMERICAN. "Freedom" "Democracy" and "Liberty" are not Christian values... their AMERICAN values and common sense values. They are not found in the bible. Biblical values are such things as piety, honesty, and kindness.
