John Locke on Separation of Church and State: A Letter Concerning Toleration
The idea of a separation between church and state that so strongly influenced our Founders was developed by John Locke in his, A Letter Concerning Toleration, which argues for a complete separation between church and state.
“For the commonwealth of the Jews, different in that from all others, was an absolute theocracy; nor was there, or could there be, any difference between that commonwealth and the Church. The laws established there concerning the worship of One Invisible Deity were the civil laws of that people and a part of their political government, in which God Himself was legislator. But there is absolutely no such thing under the Gospel as a Christian commonwealth.
There are indeed, many cities and kingdoms that have embraced the faith of Christ, but they have retained their ancient form of government, with which the law of Christ hath not at all meddled. He, indeed, hath taught men how, by faith and good works, they may obtain eternal life; but He instituted no commonwealth. He prescribed unto His followers no new and peculiar form of government, nor put He the sword into any magistrate’s hand.”
Jefferson had this in mind when he wrote his letter to the Danbury Baptist Association in 1802:
“Believing with you that religion is a matter which lies solely between Man & his God, that he owes account to none other for his faith or his worship, that the 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.“
Extra special bad news for the American Theocracy Movement:
Treaty of Tripoli
Authored by American diplomat Joel Barlow in 1796, the following treaty was sent to the floor of the Senate, June 7, 1797, where it was read aloud in its entirety and unanimously approved. John Adams, having seen the treaty, signed it and proudly proclaimed it to the Nation.
Art. 11. 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 tranquillity, of Mussulmen; and, as the said States never entered into any war, or act of hostility against any Mahometan 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.
