It was a number of things that caused me to wake up. I served as an elder from 1972-1984. During that time we saw the liberal reforms of Watchtower Vatican II replaced with the repression of the 1980s and Witch Hunts for “apostates.” Of course being an elder you have a front seat to observe all the politics that goes on in the congregation, and it was obvious that the Holy Spirit had nothing to do with the appointment of elders or MSs.
Then in 1982 while preparing a Public Talk on the Trinity the outline referred to a Watchtower, which I consulted to get a better grasp of the subject. This Watchtower quoted from J.N.D. Kelly’s Early Christian Doctrines, and I happened to have a copy in my library. But I found that the Watchtower quoted Kelly out of context. Be suspicious whenever the Watchtower uses the ellipsis in quoting a non-JW source. In fact I found more quotations taken out of context to support the Watchtower’s anti-Trinitarian doctrine. It was this discovery of the Watchtower’s scholastic dishonesty that set off more alarm bells. By 1983 I had serious doubts about the JW religion.
But in the spring of 1984 I read COC, and this confirmed that the Watchtower was not God’s organization and my resignation as an elder and my exit from the Watchtower cult soon followed.
