For years Watchtower has taught that some of the people (anointed) who saw the events of 1914 will be alive to see the end of this system of things. 102 years later and the end is nowhere in sight; another failed prophecy.
To remedy the situation they have concocted some 'new light' in the form of the overlapping generation doctrine. This new doctrine essentially states that the generation of 1914 consists of two groups of anointed whose lives overlap. As long as you were born and baptized while an anointed person from 1914 was alive then according to them you also form part of the same generation of 1914.
So for instance, if you were born 1980 and baptized 1992 then you can be part of the 1914 generation. This is so stupid, its unbelievable that anyone would actually accept this new doctrine. Its obvious that Watchtower is merely trying to buy itself some more time. What's next? Will they then say that a third group of anointed overlaps with the second and therefore forms part of the same generation? Or even a fourth or fifth?
Everyone knows what a generation means; except for the Kool Aid drinking Witnesses. I think this new doctrine is one of the things that has woken some of them up.
