My thought and your comments. I see this as a start to revise the belief to make the 144,000 a symbolic number and not literal. It would not be hard to do and would produce very little complaints.
I used to brush this idea aside, but now I think it could be a good possibility.
They still would have to believe in two clasees of Christians, but instead would teach that they just don't know exactly how many are in the heavenly kingdom. It would be a shaker, but I think they could get away with it.
Of course, it could be a very damaging thing as well. I think where they have it now is probably where they will keep it. The only reason to change it would be for exciting the rank and file.
