The United States is a Christian nation, eh? Not according to Article 11 of the Treaty of Peace and Friendship with Tripoli, ratified by the Senate on 10 June 1797. 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.
So, to further refute the claims of certain high-minded moralistic conservative Christians, the United States was not founded as some new Christian utopia, but rather as a tolerant and secular state. Once again... the GOVERNMENT of the UNITED STATES is NOT founded on the Christian religion.
Hopefully that comes in loud and clear.
