Chakka, I beg to differ. There are thousands of pieces of the jigsaw, and apart from the magic, none of it should be deemed irrelevant without investigation. It's impossible for me to give you 'green' and 'red' verses. For one thing I'd never find the time, and for another, we have to look at the individual pieces to see which, if any, of them fit other pieces, and whether or not history holds any verification. For example, the New Testament tells us Jesus died on the cross, but investigate the story in the light of our current knowledge of human physiology, and you'll find there's a very good chance he didn't. What verse do you expect me to find that in? Likewise, it's highly unlikely that Jesus was born in Bethlehem, or at the time stated, but without comparing the information given with historical records, it would be impossible to reach that conclusion.
You are clearly aware that the New Testament is not the only source of information, but I don't agree that anything written subsequent to that is automatically irrelevant because, like the New Testament, we have no idea where the information contained therein originated. For all we know, it may have come from earlier and, as yet, undiscovered documents. If we all do as you do and dismiss the whole lot as fiction, we're never going to discover anything near the truth. Just as well for us that Heinrich Schliemann had a fascination for the Iliad! The fact is you, like the rest of us, have no idea what happened - or indeed if anything happened at all. None of us can possibly claim to know, but in my opinion it's a mistake not to attempt to find out.
