One of the problems the WTS has is there are some long time indoctrinated members who over time question doctrines as when they were first
introduced to them. This generation scenario has popped up due to nothing transpiring as the WTS said it would.
Once you get past 2014, you've pretty well diminished the generation that saw/witnessed the events of 1914.
Interesting that this new light didn't come up until the old light transpired.
They had the option of dismissing 1914 off the doctrinal chart and it could have been done so since it really is a non-biblical dating
calculation. But since its has so much impertinent importance to the end time doctrine, something different had to be established
and this what they came up with, a spin on the meaning generation, a new definition created by the WTS. itself.
Another approach they could have taken is well people lived so much longer in biblical times than they do today so hence
a biblical generation is to be perceived longer in years.
Well it is god's own organization so who else would have that over powering control of the meaning of words ?
