Can someone supply me with a single passage in any of the founding documents of the United States of America that specifically mentions the "Separation of Church and State"?
No such clause is written in the U.S. Constitution.
"28. Eliminate prayer or any phase of religious expression in the schools on the ground that it violates the principle of “separation of church and state.” (from
The Naked Communist,1958, by ex-FBI agent Cleon Skousen).
Supposedly, Thomas Jefferson is who came up with the clause in his personal writings. That's where some Leftists claim it from (Thomas Jefferson). Yet Jefferson and Franklin were closely associated with socialists in France, and they both traveled back and forth to France as ambassadors. There was quite a riff among the early founding fathers because of their political associations.
The Communist Left are the main ones that have used that separation of Church and State ploy, simply because they realize how important it is to get Godly values out of the state apparatus so as to allow secularism to get control. And once secular humanism, or the "age of reason" thinking is dominant, then Socialist-Communsit principles can be substituted in its place. Those like Jefferson and Franklin were very much into the European "age of reason" and "enlightenment" type of thinking. Many of the early founding fathers were involved in Masonry, but there were two main branches of it in Europe at that time, and there was a huge riff between them. It's very important to know this, because it reveals part of the reason for a riff between some of the early founding fathers.
The British mason John Robison specifically wrote his 1798 book
Proofs Of A Conspiracy documenting Weishaupt's Bavarian Illuminati takeover of Continental Masonic lodges on the continent of Europe
as a warning to masons associated with the British lodges (as a warning to the Church and western governments too).
Masonry began in Great Britain according to Robison, and it had only 3 degrees. Early masonry on the continent of Europe, like in France, Germany, etc., got its roots from British masonry (per Robison). What Weishaupt's Bavarian Illuminati Order sought to do, and did, was to take over the highest positions within Continental masonry (in countries like France, Germany, Switzerland, etc., only countries on the European continent). Those lodges on the continent became known as 'blue lodges'. And they had many degrees added... to the original 3 degrees from British masonry. Weishaupt's Illuminati added them. Robison goes on to reveal how a lot of those added degrees to the masonic lodges on the continent of Europe were bogus, and involved occultic charlatans and all sorts of shady characters involved with the movement. He used the discovered secret documents and personal letters of Weishaupt's Bavarian Illuminati to prove it, which included an outline of the initiatic structure and degrees. So originally, in British masonry, the original masonry, there never was any more than the basic 3 degrees. Thus the masonic 'French connection' which those like Ben Franklin and Thomas Jefferson had as ambassors is revealed in some of the ideas of their writings, and was most likely the cause of a rift they had with others like George Washington and John Adams, and the reason for two opposing works on statism,
The Federalist Papers, and
The Anti-Federalist Papers.
