Great commenets everybody.
Leolaia I just wanted to comment on a few specifics you pointed out:
I suppose there was an inertia to this system and Franz did not see it as a matter of concern. Today, with 2014 approaching soon, the longe durée is becoming more and more conspicuous.
I feel the same way. Neither Franz or Knorr ever put as much of themselves into the theology of the religion as Rutherford did. Franz especially was a man who elaborated and refined the ideas of Rutherford. That was always his foundation. Franz and Knorr actually did have the power to move past Rutherford, but they never really did. Instead they kept the teachings of Rutherford at the center. They where the "disciples" of Rutherford in every way, maintaining the traditions of their "master" throughout their entire lives.
Up untill the past decade those who continued the traditions of Rutherford have continued to dominate the leadership of the faith. As time progresses however there are very few people inside the organization that where alive during the Rutherford years. They are quickly dying off and will be mostly gone within the next decade or so. Once they are gone we are left with the followers of the followers.
One thing I feel that makes the Jehovah's Witness so confusing is that those who took the lead after Rutherford decided to systamatically keep and refine his philosophy without ever giving him proper credit. While other modern "restorationist" faiths show a great deal of respect for their founder (mormons, christian science, adventists) generations of Watchtower leaders have continued to downplay the importance of "individuals" and instead directed the credit towards the Watchtower corporation in general. This has created an "image" of Jehovah's Witnesses that is mostly fantasy, namely that the organization (and no single person) is the source of the majority of teachings.
Understanding exactly who and what Jehovah's Witnesses really are and why the believe what they do becomes rather complex. Are them from Russell, Rutherford, Knorr & Franz, a mix of all of these? I firmly believe it's all Rutherford. The myth told by Watchtower leaders that the organization has been refined by God is just that, a myth. Rather Rutherford set up the religion and his loyal followers that continued to lead the watchtower refined his ideas. Because of this it's no surprise that in Watchtower theology Russell never fulfills any scripture and Rutherford fulfills dozens of them. Additinally, nobody fulfills scripture after Rutherford according to current truth.
