"Being the self-appointed sole channel of communication with God puts them in an obligatory position to thoroughly search the scriptures with humility and honesty. They should be praying incessantly to be guided by HS and then seeking to follow its leadings through the pages of the Bible to find answers. "
Therein lies the problem. When you have 7 yes men that have been thrust into the role of leadership.....they don't know what to do. The only option is to hold tight to the existing doctrines and decisions because.....well......they were made by the holy spirit so they can't be wrong, can they? Any revocation of a damaging doctrine (or even suggestion to do so) could be construed by the other 6 as the first step to apostacy. And then that man would be in Ray Franz' shoes.
It would not shock me at all if certain men on the GB either now or in times past have truly wondered to themselves if a particular doctrine is correct. But then they quickly remind themselves that they are imperfect....and such a thought is just Satan trying to get them to be like Ray Franz so they quickly dismiss it
