It is a fascinating question, Big Dog. If the R&F suddenly couldn't even access the Kingdom Halls and all the Bethel branches were silent, what would they do? Would local elders try to make alternative arrangements for meetings and field service? What would field service be about, if not being fed with materials provided by Bethel?
It would be pretty hard to argue that it's God's earthly organisation if it was suddenly not there anymore. I predict a new offshoot: Jehovah's Continuing Witnesses.
Without COs applying pressure from Bethel, would the average BOE even bother to try to resurrect the organisation from the ashes?
