Not to get off topic, but it is kind of funny how many Witnesses have the erroneous view that all ex-JW Chrstians "go off the deep end" and become trinitarians.
I am a Christian who does not believe in the trinity. I believe that I have approached it with an open mind and simply have not been able to find compeling evidence in the Old or New Testament for it's scriptural validity. This is one of the very few points where I can say that I still agree with the WTS. However, this is a doctrine that I have absolutley no interest in arguing over.
I attend a group / meetup of Christian ex-JWs that has roughly 8 to 10 people in attendance. It's funny, but roughly half of the group are very firm trinitarians, and there about four of us who do not believe in the trinity. I have never seen an argument over this topic; because all of us have simply agreed to respect each other and not venture into debates about this doctrine. The topic has certainly come up; but we have agreed to show respect for each others views.
All of us: the pro and anti trinity folks have acknowledged the presence of various verses which are probelmatic to our own positions; but there has never been anything that comes close to an argument in our group. Personally, I don't see much point in trying to win a rhetorical contest on this issue; because I know that I never will.
"We agree to disagree" is one of the most wonderful pharases ever invented.
