It is very confusing.
On page 23, paragrah 11, they say that the apostles would no doubt have understood that they were to be part of that generation that would not pass away until all these things occur. Now - when did the apostles live and die? 33CE. That tells us that the generation that would not die, had to have been in 33 CE by the Societies own admission.
Now, that explanation gets dropped.
On page 24 and 5 the WT goes back to the signs and the time of the end, speaking about today by saying that everything started in 1914 making the application that the annointed make up that generation. This ignores the fact that on the previous page, they said that the generation started in 33CE before the time of the end in 1914.
They don't link it or tie it in - there is no cohesion. It makes no sense. I have no idea how any JW can explain it away or how they can buy into it. It's ludicrous.
