"There is no debate or question concerning Russell's being influenced by some of the unique Freemason theological ideas of which Pyramidolgy stems from"- Finkelstein
Actually this too is open to debate. Vienne rightly points to Smyth and Seiss as the most influential writers that influenced Pastor Russell's interest in pyramidology. However, Russell's 'theological' interest in the Great Pyramid may have been 'refined' by another minor thinker involved in the 'pyramid' discussion:
" A few year's after Prof. Smyth's return, came the suggestion that the Great Pyramid is Jehovah's "Witness", and that it is as important a witness to divine truth as to natural science. This was a new thought to Prof. Smyth, as well as to others. The suggestion came from a young Scotsman, Robert Menzies, who, when studying the scientific teachings of the Great Pyramid, discovered that prophetic and chronological teachings co-exist in it." - THY KINGDOM COME 1908 edition STUDIES IN THE SCRIPTURES pg 320 paragraph 1 (italics mine)
"In a letter to Prof. Smyth, Mr. Robert Menzies, the young Scotsman who first suggested the religious or Messianic feature of the Great Pyramids teaching,......"- THY KINGDOM COME 1908 edition STUDIES IN THE SCRIPTUES pg 337 paragraph 1 (italics mine)
These quotes seem to indicate the Russell admits that he got his religious or theological inspiration for his own brand of pyramid quackery not from Freemasonry but from a gentleman named Robert Menzies.
