Do not let anyone claim the tribute of American patriotism if they ever attempt to remove religion from politics.
George Washington from his Farewell Address to the Nation:
Our laws and our institutions must necessarily be based upon and embody the teachings of the Redeemer of mankind. It is impossible that it should be otherwise; and in the sense and to this extent our civilization and our institutions are emphatically Christian.
Church of the Holy Trinity v. United States, 1892.
