The United States is declared a Christian Nation.
EDIT: If I remember correctly, that is.
“The United States is not a Christian nation any more than it is a Jewish or a Mohameddan nation” -John Adams
“The government of the United States is not in any sense, founded on the Christian religion. The United States of American should have a foundation free from the influence of clergy” - George Washington
“Religion and government will both exist in greater purity the less they are mixed together” -James Madison
“Christianity is the most perverted system that ever shown on man” -Thomas Jefferson
“Lighthouses are more useful than churches” -Benjamin Franklin
It is of important note that “Under God” in the pledge of allegience as well as “in god we trust” on the money were added in the mid 1950’s as propaganda against “godless communism”
The original pledge of allegiance, as written in 1892 goes like this:
“I pledge allegiance to my flag and the republic for which it stands: one nation indivisible with liberty and justice for all”
