That's it! Once you are no longer captive of that particular concept, the GB are revealed as blind guides. The "Channel of Truth" dogma is their claim to power. Without that, they have nothing.
The main JW doctrines are:
1) WTBTS = God's only channel. ( Easily debunked )
2) Jehovah is God's name as restored by the WTBTS. This is used to prove that they are the one true religion. ( Easily debunked )
3) Paradise Earth. ( Specualtive at best.)
4) Two-tiered Xian hierarchy. ( Easily debunked )
5) Works based salvation. ( Easily debunked )
You may be noticing a pattern. The truth is that everything else falls apart when Doctrine #1 is proven false. Dubs put up with a myriad of abuses becuase of Doctrine #1.
The only way to divorce Doctrine #1 from your psyche is objective research. This requires access to accurate information concerning the WTBTS. This is precisely why the WTBTS goes to great lengths to obfuscate their history while launching forth a never-ending torrent of propaganda. The irony is that Dubs are afraid to doubt becuase of Doctrine #1, so they fear objective research.
I think Jacko's sole reason in calling the GB "G.O.D", was to try and decieve the RC into thinking the GB have nothing to do with corporate policies. The want everyone to believe that they are just humble old gurus who basically read the bible and pray every day, all the while some "others" are writing magazines and deciding what goes into the Shepherd book. The RC wasn't buying it.
