Cygnus,
In another thread you were talking about the logic of certain teachings. Let's assume, for the sake of argument only, that God does work through a single organization to which one must belong to achieve salvation. Is it logical that this organization would be a minor offshoot of Protestantism? After all, that excludes the vast majority of the world's population from the get go - why should someone born Chinese or Indian have an unfair disadvantage, based solely on where they were born, when it comes to joining that organization? It's hard enough for them to convert to Christianity let alone to a minor sect with a disturbing background and a track record of predicting the end repeatedly with devasting results for many of their followers.
As for mistakes, what makes the WTS's mistakes forgivable and those of other religions worthy of their clergy and their members being slaughtered - dead for eternity? Just read some of Rutherford's books from the 20s and 30s to see what will happen to the clergy and those who associate with them.
And finally, Cygnus, what do you think about the logic behind the WTS affiliating with the UN - is that a "forgivable mistake" when countless JWs have been jailed, killed or dfed over various aspects of "neutrality."
