I think that if this arrangement is true, it certainly makes for interesting thought regarding the elders.
For instance, each elder (or therabouts) had oversight over a group, and they were their own responsibility. Now with this new arrangement, it will mean that (I reckon) the same elders will do a rota for the book study meeting, leaving the elders who once had some responsibility overseeing a group now with barely any privileges at all.
Just a thought.
Does that mean that meeting for field service will now also take place every weekend at the hall? We used to meet in people's homes. What about the midweek arrangements? Oooh, I must be so bored at work if I have resolved to wondering about this now.
