If you read Carl Jung and myth scholars, the stories serve a purpose, whether they are provable or not. Certain themes repeat throughout human civilizations and time b/c certain things are common to the human condition. I no longer care whether the story actually happened. Christianity speaks to me b/c I was raised in a Christian culture. How can I say Christ only and not Buddha?
The WT and other fundamentalists have a very unsophisticated postion. The stories are true beyond proof. It doesn't mean they actually happened. Altho sometimes when I read my Bible in consecutive verses, I come across a comical, odd story that does not fit into the author's grand scheme or one that is so over the top I believe no one would invent it. I doubt most Christians today believe in a literal view of the Bible.
Within the past few years I read Karen Armstrong's book on God. During a specific sliver of time, economic, political, and social condtions aligned throughout earth to produce what we call the great religious traditions - sans Christianity. Judaism, Buddhism, HInduism, and can't recall what else. The Axis religions.
I have a personal take on the gospels. Many things may have happened as recorded, some things are clear embellishments and knowing the author's purposes and social history gives insight into why certain events are exagerrated, and some I don't think happened. One item I don't believe are the geological and weird events like the curtain in the Holy of HOlies being ripped at Jesus' death. If such events did occur, they would be reported in Roman and Jewish sources, too. I find much more proof and truth in a nuanced view than in the Witness system.
I can't prove something but not every Witness is ignorant. The writers and GB must have some savvy. I've always wondered if they just go through motions b/c they know no else what to do. Priests do it. My own faith waxes and wanes and I know not why.
