Most mainstream Christian churches share a core of accepted important doctrines, which could fit on a postcard. (After leaving the WTBS I attended an independent Evangelical church that did precisely that).
Those core doctrines concern the nature of Christ, salvation through faith, baptism, and the importance of scripture. Everything else is regarded as secondary and a matter of personal belief. I have a five volume encyclopedia of the bible that will lay out multiple interpretations of an idea, followed by the arguments for each, and then leave it up to the reader to decide what he thinks.
The problem the WTBS has in this regard is the need to be right about every single thing they can think of. Personally, I think some parts of the Bible are there to get us to think about the questions, not to provide answers.
