But then, not all their changes make sense in my opinion. I don’t see the rationale for not counting time any more for example. It seems like a needless change with only downsides. Although I suspect in that case they may possibly have legal reasons for the change they are not disclosing.
I completely agree that not all the GB changes make sense, but I disagree that the removal of counting time was one that didn't. On the contrary, I never saw any scriptural basis for reporting time - it was just a bureaucratic exercise created by the corporate-minded. The Org always trotted out a few verses like Mark 6:30 and Acts 2:41 to support the idea, but all the verses they cite centre around experiences being shared, numbers of people being counted (eg newly baptised), etc, but never hours and times spent. The best you get is comments like "at sunset" such and such happened, "by the third hour" the disciples arrived somewhere, or they spent "many days" in this town or village, etc. AFAIK there is no basis in the gospels to support tracking hours spent by individuals on preaching, and it has created all kinds of problems that are now a legacy, like judging "spirituality" purely on numbers, and encouraging over-reporting which has now led to a lot of the problems they have with inaccurate numbers.
I think they relied for too long on the numbers coming back from the field when planning halls, literature production, and so on. That's easy to do when the numbers appear to grow and look healthy, but when you begin to see a mismatch in what's being reported with the evidence on the ground (eg: relative 'productivity' of ministry now not producing as much 'fruit') it becomes a serious problem. And then you start to see the numbers stall in many places, or even go into decline. The only way to 'cure' that (or at least remove the annual embarrassment) is to ditch the whole thing.
In all honesty, most of their recent changes I consider right, and long overdue: beards for brothers not being an issue, no more reporting time unless you have volunteered for that extra duty (by pioneering), trousers allowed for sisters, etc. Even the amendments to "disfellowshipping" make more sense than the old arrangements, although they don't go far enough.
Coming back to the 144,000 question, I suppose it is possible they could say that, while the number going to heaven to 'rule as kings and priests' may be limited compared to those 'subjects' on earth, it doesn't have to be exactly 144,000, thus the number could still be said to symbolic, without changing the overall teaching. But if they do say that, it would still seem to me to be a major fudge of the issue, and will add to the increasing realisation in the R&F that the current GB are losing their grip on the doctrine.
