As some have recently posted here, there does seem to be a shift going on in their self-interpretation(s) of what happened in 1918 and 1919. If we can look past all the details that emphasize the poor thinking and poor wording (or contradictions/just plain craziness/insignificance) of their message, something bigger seems to be afoot. What is it? They appear to be attempting to redefine the meanings for some "prophetic" scriptures in light of themselves. A few ideas/observations:
1. They are trying to somehow fill the void they have themselves created from their rejecting Freddie Franz's (FF) type–anti-type postulations. They are not as intelligent as he was, in fact, are much dumber, so are struggling to make their new proposals in some way work, at least in their own minds.
2. Many Witnesses have often felt that some small assembly in Ohio during the 1920s seemed too insignificant for a plague in the book of Revelation to have been poured out upon the earth, etc., etc., and that such an interpretation was just too obscure to believe. Likewise FF's ideas that the big gap in Western civilization's history from the end of the first century when the apostles were gone (or the Roman empire falling) to Charles Taze Russell's (CTR) day (or the rise of the "Anglo-American world power") had more significance than FF would allow.
3. What we may be witnessing then is a return to CTR's ideas that people/key figures from the Protestant Reformation (or even earlier) onward, or certain features of Western civilization's history, were foretold in scripture. He identified Luther, Wycliffe, and others with passages in Revelation and the Hebrew prophets. GB 2.0 seem like they may be going back to such a view. Reported on this forum was a post that a Bethel heavy recently made a statement in harmony with this. Furthermore, the Bible display/museum they are working on contains copies of translations they have been collecting that would also be in agreement with this. Evidently if you were some figure in pre-WTS Protestantism and you used "Jehovah" for the divine name in your Bible translation, then you may rate a place in upcoming WTS pontifications of prophecy!
Of course, another factor likely at work now is their interest in maintaining the importance of 1914, so that might somehow figure in here as well.
Just some thoughts...
