The persons who studies the mystical/occult topics agreed in say that the Occult devilish knowledge that hold the Jesuits now before them was held by the Rosacrucians.
Remember, the jesuits, with this occult knowledge created the satanic organization named the Illuminati and several others evil groups.
The Occult knowledge road is like this:
Babylon--->
Khabalah--->
Gnostics--->
Templars (great influence of several islamics sects, like the asshasshins)--->
Rosacrucians--->
Jesuits.
You can see 2 great lectures about this:
Bill Shnoebelen's
The Illuminati from within (greeeat lecture) and
Walter J. Veith's
The Secret Behind Secret Societies (great to, haha).
Cheers and I hope this will be usefull, haha!
