Albert Pike:
"The Knights Templar, he continued, were from the very beginning "devoted to . . . opposition to the tiara of Rome and the crown of its Chiefs. . ." The object of the Templars, he said, was to acquire influence and wealth, then to "intrigue and at need fight to establish the Johannite or Gnostic and Kabbalistic dogma. . ."
