What really did it for me was when I confided in another elder about my concerns about the blood issue. I asked him not to say anything while I worked it out in my own mind. My wife and I went on vacation and when we got back I was asked to meet at the KH to talk about memorial arrangements with the other two men on the service committee, I was the PO and the service overseer was the one I confided in. When I got to the KH I quickly found out the real reason they wanted to talk to me was about the blood issue. The SO told the rest of the body about my concerns and I was soon removed because of my doubts. That opened the gate to research the issue more throughly and I purchased CoC by Ray Franz. I first read it in secret then shared some things with my Wife.
We stopped going to meetings 3 years ago and life has been great ever since
