Brooklyn has long differentiated between those CLAIMING to be anointed versus those on the Governing Body of whome there 'can be no doubt of their status.'
It is also a way to keep those upstart female 'chosen ones' from trying to teach while still alive on earth. They only have special status once they die and actually sit with Christ in the heavens. (gawd it is tough to type this crap and not throw up a little)
It is only the GB and the Nethinem class that have any special insights per the WTBS. Everyone else must be in subjection to them.
