I had in advance made the study conductor aware of the change - and he answered that he was aware of it, and that a couple of the other elders had been talking about it for months, as they had been told about it by someone who had been at the annual meeting. But my concern towards him was the lack of Scriptural support for the overlap understanding. During the study, both before it and before/during and after the paragraphs in question, emphasis was put on the new or changed understanding, so it was very well stressed. The question was asked what Scriptural backing there was for the change, and one sister replied - the only one replying to the question - that there really was no explicit backing given, except for the reference to Exodus and Joseph and his contemporaries, that when those died who had experienced the entering into Egypt it was stated that that generation died. And the conductor also stated that this was the backing given.
So I think that it was well covered here as far as it was pointedly stated that it was a changed understanding, and that the Joseph reference was the backing given, and also that it supposedly would be dealt with at the DC.
