Well, WT did insert in the rNWT (aka, "The Silver Sword") that there was a governing body in Jerusalem. So, it must be true.
You see, the best way to advance a doctrine that isn't in the Bible is to revise your old Bible and actually put the errant doctrine in the new Bible. Problem solved.
As at least one scholar said of the NWT (aka, "The Old Busted Sword"), WT formulates doctrine first, then creates their own Bible to support that doctrine.
As OT and Terry pointed out, Paul wasn't consulting any alleged "governing body" for his assignments. He worked all on his own. If WT wants to use that info. as precedent, then JWs shouldn't have to consult the present GB about anything. ANYTHING !!
Finally, the Acts account clearly says that women were present at the "governing body" meeting in Jerusalem and instrumental in the decision-making process. If that account is precedent, why are their no women members on the GB today?
