I was able to spend some 1 on 1 time with Guy Pierce before he died. He was very busy, so I appreciated the time he took to talk with me. I resisted the urge to ask him some spot questions about some things that were disturbing me.
He quizzed me on some bible passages, which I enjoyed. But I remember one question about the meaning of a scripture in Romans. I told him from the context it was very easy to understand. He instead pulled out a 1974 or 1975 WT and said "that's what those scriptures say, but notice how the Watchtower explains this scripture. It's very important that we keep up with our current understanding of things, even if it's many years old."
That's when I realized that WT publications trump the bible.
The gb members probably avoid the r&f just because they know they are being examined under a microscope. But hey, what do you expect when you are the the only divine channel of communication on earth?
