ILLUMINATI PROJECT: MEMO #1
The first reference I've found is in Violence by Jacques Ellul (Seabury Press, New York, 1969). He says (pages 18-19) that the Illuminated Ones were founded by Joachim of Floris in the llth century and originally taught a primitive Christian doctrine of poverty and equality, but later under the leadership of Fra Dolcino in the 15th century they became violent, plundered the rich and announced the imminent reign of the Spirit. "In 1507," he concludes, "they were vanquished by the 'forces of order'-that is, an army commanded by the Bishop of Vercueil." He makes no mention of any Illuminati movement in earlier centuries or in more recent times. I'll have more later today.
P.S. I found a little more about Joachim of Floris in the back files of the National Review, William Buckley and his cronies think Joachim is responsible for modern liberalism, socialism and communism; they've condemned him in fine theological language. He committed the heresy, they say, of "immanentizing the Christian Eschaton." Do you want me to look that up in a technical treatise on Thomism? I think it means bringing the end of the world closer, sort of.
