Beneath all these occult sects one common source of inspiration is to be found--the perverted and magical Cabala of the Jews, that conglomeration of wild theosophical imaginings and barbaric superstitions founded on ancient pagan cults and added to throughout seventeen centuries by succeeding generations of Jewish occultists.[429] This influence is particularly to be detected in the various forms of the Rose-Croix degree, which in nearly all these associations forms the highest and most secret degree. The ritual of "the eminent Order of the Knights of the Black Eagle or Sovereigns of the Rose-Croix," a secret and unpublished document of the eighteenth century, which differs entirely from the published rituals, explains that no one can attain to knowledge of the higher sciences without the "Clavicules de Salomon," of which the real secrets were never committed to print and which is said to contain the whole of Cabalistic science.[430] The catechism of this same degree deals mainly with the transmutation of metals, the Philosopher's Stone, etc. In the Rite of Perfection as worked in France and America this Cabalistic influence is shown in those degrees known under the name of the "Ineffable Degrees," derived from the Jewish belief in the mystery that surrounds the Ineflable Name of God. According to the custom of the Jews, the sacred name Jehovah or Jah-ve, composed of the four letters yod, he, vau, he, which formed the Tetragrammaton, was never to be pronounced by the profane, who were obliged to substitute for it the word "Adonai." The Tetragrammaton might only be uttered once a year on the Day of Atonement by the High Priest in the Holy of Holies amid the sound of trumpets and cymbals, which prevented the people from hearing it. It is said that in consequence of the people thus refraining from its utterance, the true pronunciation of the name was at last lost. The Jews further believed that the Tetragrammaton was possessed of unbounded powers. "He who pronounces it shakes heaven and earth and inspires the very angels with astonishment and terror."[431] The Ineffable Name thus conferred miraculous gifts; it was engraved on the rod of Moses and enabled him to perform wonders, just as, according to the Toledot Yeshu, it conferred the same powers on Christ. This superstition was clearly a part of Rosicrucian tradition, for the symbol of the Tetragrammaton within a triangle, adopted by the masonic lodges, figures in Fludd's Cabalistic system.[432] In the "Ineffable degrees" it was invested with all the mystic awe by which it is surrounded in Jewish theology, and, according to early American working: "Brothers and Companions of these degrees received the name of God as it was revealed to Enoch and were sworn to pronounce it but once in their lives."
