In this past Sunday's Watchtower lesson, which has been discussed at length on this board, the GB/Writing Committee used a key weasal word that we will probably see again. The exact quote is: "We UNDERSTAND that in mentioning 'this generation,' Jesus was referring to two groups of anointed Christians."
This goofy teaching is merely a patch until they can devise something more plausible, or until some event occurs that they can latch onto that will make this teaching more acceptable to the R&F. I have no idea what that might be but my guess is that they just tossed up a hail mary pass to try to buy themselves more time. One of the GB--I believe it was Lett--in rolling this out said, "We LOVE this teaching!" In other words, "For the moment it suits our purposes perfectly!"
At some point we'll read that this was only their "understanding" and that they did not claim that it was divine inspiration, so now HERE is generation teaching number SIX, which is of course the REAL explanation of this text!
