“They knew that to put God in the constitution was to put man out. They knew that the recognition of a Deity would be seized upon by fanatics and zealots as a pretext for destroying the liberty of thought. They knew the terrible history of the church too well to place in her keeping or in the keeping of her God the sacred rights of man. They intended that all should have the right to worship or not to worship that our laws should make no distinction on account of creed. They intended to found and frame a government for man and for man alone. They wished to preserve the individuality of all to prevent the few from governing the many and the many from persecuting and destroying the few.”
― Robert G. Ingersoll, Individuality From 'The Gods and Other Lectures'

“The government of the United States is not, in any sense, founded on the Christian religion.”
― John Adams
