Undoubtedly, Ray Franz believed and supported the Watchtower's views about 1975. (All of us in the organization at the time did.) The significance of Ray's controversy with the Governing Body is that he started sharing some of his findings and doubts in the course of his research. For a very brief period there was a spirit of freedom at Bethel. Small groups began to study the Bible. They shared their research findings with each other. Important questions were being asked about some of the fundamental teachings of the Watchtower Society.
What followed was a tragedy. Members of the Governing Body saw this as a challenge to their own authority. The witch hunt that followed destroyed this era of freedom and purged the only men that could have made a difference in the entire organization.
However, thanks to men like Ray Franz and others who were caught in the paranoia of the Watchtower Society, many of us learned about the inner workings of the secret leadership and were encouraged to question the entire system. I, for one, will always be very grateful to these men for opening up my eyes to the real "truth" about the Watchtower Society.
