“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.”

“Persecution is not an original feature in any religion; but it is always the strongly marked feature of all religions established by law.”
― Thomas Paine, The Age of Reason

“As the Government of the United States of America 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 Mussulmen [Muslims],—and as the said States never entered into any war or act of hostility against any Mahometan [Mohammedan] nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.

“...legitimate powers of government reach actions only, & not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between Church & State. Adhering to this expression of the supreme will of the nation in behalf of the rights of conscience, I shall see with sincere satisfaction the progress of those sentiments which tend to restore to man all his natural rights, convinced he has no natural right in opposition to his social duties.”
