There is some quote by (one of the Adams?) stating that our form of government is only meant for a Christian, moral people. (I probably mangled this, but its close).
We are living on a reservoir of Christian faith that founded this great nation. Sadly, that reservoir is declining, hopefully it can be turned around.
"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."
