Hi, Jayhawk!, just remember I am explaining the WTS view not my own.
In early Christian times, all Christians were anointed. The WTS believes though that there was a special group of anointed who made up the governing body and it was through them that things were directed. Also, in those times, some of the anointed had the gifts of the holy spirit, able to speak in tongues, prophesy, write inspired writings, heal, and some resurrect the dead, but not all the anointed had these abilities.
The WTS teaches that the GB functions as a group not as individuasl, so theoretically one member does not come and say I thought this and the rest then fall in line. They teach that they consider the Bible and then discuss it and then unanimously decide.
But we know that is a bunch of crap. They neither consider the Bible, nor discuss it as a group or decide unanimously (2/3 vote I think).
You are trying to make sense of something that makes no sense. The WTS makes many public statements but privately practices something completely different.
It was Hayden Covington that stepped down. He was later DF'd but reinstated and after that considered himself one of the anointed and partook until his death. Actually, there was no "governing body" at that time, but a president, vice-president, secretary, and treasurer and a board of directors. Since these were really corporate positions, there was no need for him to step down.
