“Catharism was the greatest heretical challenge faced by the Catholic Church in the twelfth and thirteenth centuries. The attempt by the Cathars to find an answer to the fundamental religious and philosophical problems posed by the existence of evil, combined with their success in persuading large numbers of Christians in the West that they had solved these problems, shook the Catholic hierarchy to its very core, and provoked a series of reactions more extreme than any previously contemplated.”

“Medievel 'Templarism' , as described by Loiseleur, recognized a d and duality of gods, one a superior being of the celestial world, who was pure spirit and perfect, the other an evil god, germinated and indeed wealth was created.”
