I held all three positions as one time or another. However, I was an elder in 1984 when I began to have doubts. In the early 1970s when Ray Franz was on the GB, the organization began to liberalize some of their rules and regulations. We jokingly referred to this as Watch Tower Vatican II. But after Ray Franz was removed from the GB the organization became very oppressive. I read Crisis of Conscience in March 1984. At the time I was Theocratic School Overseer and a Congregation Book Study Conductor. I think that the JWs still use those terms. I was also averaging 20 hours a month in field service.
However, after reading C of C there was no way I could remain a JW in good conscience. So in September 1984 I resigned as an elder and by October I had ceased attending meetings.
Sincerely,
Athanasius
