It is contended by many that ours is a Christian government, founded upon the Bible, and that all who look upon the book as false or foolish are destroying the foundation of our country. The truth is, our government is not founded upon the rights of gods, but upon the rights of men. Our Constitution was framed, not to declare and uphold the deity of Christ, but the sacredness of humanity. Ours is the first government made by the people and for the people. It is the only nation with which the gods have had nothing to do. And yet there are some judges dishonest and cowardly enough to solemnly decide that this is a Christian country, and that our free institutions are based upon the infamous laws of Jehovah.

— Robert Green Ingersoll, “Individuality” (1873)
