In 1924, Judge Rutherford published an article which referred to the Great Pyramid as "the Scientific Bible" and added that measurements on the Grand Gallery inside the Great Pyramid confirmed the dates 1874, 1914 and 1925.
1925 was the famous blowout date for the return of "ancient worthies" about which the Judge said, "I made an ass of myself."
Just four years later, Rutherford did one of his famous about-face reversals.
Whereas previously the Watchtower had taught that the Great Pyramid was probably built by Melchizedek, or Shem;*
Rutherford now said the Great Pyramid was constructed "under the direction of Satan the Devil." **
