As the government of the United States is not, in any sense, founded on the Christian religion; as it has in itself no character of enmity against the laws, religion or tranquility of Musselmen [Muslims] ... it is declared ... that no pretext arising from religious opinion shall ever product an interruption of the harmony existing between the two countries.... The United States is not a Christian nation any more than it is a Jewish or a Mohammedan nation.
