I can confirm this wasn't isolated to one CO. I (unfortunately) listened to this same talk Sunday at the CO visit and while he didn't mention this was a completely new teaching, he spent at least 10 minutes of the last part on Sunday speaking on this subject. A couple of things he mentioned:
Compared the generation mentioned in Matt 24 to the use of the word generation to describe Joseph's brothers
My comment - exactly, a group of brothers would make up a generation even if there was a good bit of age between them but to include parents + kids in a generation is stupid and incorrect. That's like saying I'm in the same generation as my grandmother because we both witnessed 9-11!
Specifically said this "generation doesn't include "new" annointed, only those who became annointed while the "first part" of the generation who saw 1914 was still alive. To illustrate, he said that Franz was the last of that first group and (direct quote) " younger members of the GB whose lives overlapped with Franz were the second group. These ones are in their 60s and 70s now so the time left is short".
My comment - I really think they are trying to set up a senario where 2034 is the new 1975. They know that an end time religion needs a date or you get what the WTS has become, a hollow shell of its former zeal. They can't risk moving the 1914 date and realize the wishy washy generation is all annointed argument didn't motivate anyone. So, they've created a 2 part generation in hopes of rejuvinating the troops. But after the meeting, not one person mentioned that they just heard a major change!
We've talked about how the WTS is at a crossroads. Do they mainstream and try to retain the 2nd and 3rd generation JWs in the West or do they go full bore into wackiness and end up with a smaller but more dedicated and motivated flock. It seems they are choosing door #2.
