The Proclaimers book, page 201 comes clean: "For some 35 years, Pastor Russell thought that the Great Pyramid of Gizeh was God's stone witness, corroborating Biblical time periods. (Isa. 19:19) But Jehovah's Witnesses have abandoned the idea that an Egyptian pyramid has anything to do with true worship. (See 'Watchtower' issues of November 15 and December 1, 1928)." That belief was also held by other religious persons but I fail to see a Masonic connection. If I remember correctly, the Witnesses did an about face claiming that the pyramid was really Satanic in origin.
Can someone scan a portion of what was said in those copies pertinent to this issue?
