Not sure I get the reasoning here...
I understand that if they expand the GB it means those who come on board must be anointed thus in esscence the GB are "appointing" but for this to have the impact of a major change it would mean that they would have to say only the GB are anointed and I can't see them do that.
The GB can add new members from a pool of currently known anointed partakers...but anointed at the moment are self-appointed (anointed)...that wouldn't change...
