finklestein: It should be realized that the Watchtower Corporation bought and sold the return of Christ as its fundamentally largest doctrine and exploited this all throughout the 20th century.
That is true, Finklestein, however, the Watchtower has done some major flips in doctrine and were successful in the past in making radical doctrinal shifts.
For example, the dramatic shift from the WTS' pro Zionist stance prior to 1925 to a 'replacement theology' was a very significant shift. And the Watchtower survived - they just did a makeover. A new name, a new structure, the old guard was thinned out, and voila! the Jehovah's witnesses was born.
Today, the same thing is happening...major doctrinal changes and shifts are part of the changing landscape. And, besides, the WTS has always been politically savvy, and frankly, the notion of a Messiah returning to lead a special group of people just isn't very politically current for global financial concerns.
