The thing that boils my piss about the J.W. org is their constant crowing that they are right and Christendom has got it all wrong.
I can remember this feeling when they used to constantly brag about how they had got 1914 right, and the other Christian religions had missed this event in heaven ! I remember sitting there during a W.T Study and thinking "I wish they could be proved wrong over this, just to shut them up". well, they were, and it didn't.
The Trinity is another exactly parallel thing, they keep on about how it is a false Doctrine, to such an extent that J.W's go to great efforts to get "interested" persons to reject the Doctrine. The problem is that the J.W org has got this one wrong too.
I don't wish to get in to a big discussion on the Trinity, but suffice to say, if you know how to read the Bible, as an Academic expert in the field would, and if you know about how Philosophical thought works, you will see how later Theologians developed the Trinity Doctrine and why, you will also understand that it isn't in any way a deal breaker as J.W org would have it.
The org hypocritically goes on about how it isn't found spelled out in a simple formula in the Bible, and developed after the 1st Century, well that rather brings us back to the Foundation Doctrine of the J.W org, the 1914 nonsense doesn't it ?
That Doctrine suffers from the above problems levelled at the Trinity, plus it is not to be found anywhere at all in Scripture, unless you are mildly insane about Biblical interpretation and understanding.
