Very scholarly. It's too bad the Witnesses aren't. And yes, I'd heard rumors for years that both Joseph Smith and Charles T Russell were Masons, and I have no doubt they were. It was quite common in their time. Pyramidology and spirtualism were both fads of their time, or scams, to be more honest.
Studying the history of religions of that time and then reading "The Power of Myth" by Joseph Campbell, wherein he also discusses the symbolism of what is on our money, our governmental seals and such in the USA, also the flag, and how many religious movements of the 17 and 1800s were steep in Masonic ideas or ritual, and how many influential people were in turn influenced by that led me to some of the same conclusions.
I never could make head nor tails of the 1914 thing. I never felt comfortable teaching it to anyone else, because I knew deep down it was Bible hopscotch of the worst kind and also, that nothing outside of WTS literature leads you to 607 as the fall of Jerusalem to the Babylonians.
The other fact that 1874 was Russells original date is pretty much buried by the WTS, but I found and read a couple of his studies in an old book store many years ago and knew that and that he was obsessed with the Pyramids. Egyptology was also a huge spiritual fad of the day. Some people still are, as a device of fiction, they come up frequently in science fiction as conduits for aliens or alien machines or power sources and such.
