"Two signs of the authenticity of the Teaching are: first, striving for the Common Weal; second, acceptance of all previous Teachings which are congruous with the first sign. It must be noted that the primary form of a Teaching does not contain negative postulates. But superstitious followers begin to fence in the Covenants with negations, obstructing the good. There results the ruinous formula: “Our creed is the best,” or, “We are the true believers; all others are infidels.” From this point it is a single step to the Crusades, to the Inquisition, and to seas of blood in the name of Those Who condemned killing. There is no worse occupation than forcible imposition of one’s creed."
