My position is that the overwhelming consensus of experts in history is that the Gospels are not reliable firsthand historical accounts. This is trivially and obviously true.
That there may be a small fringe group who disagree does not refute this. They are the equivalent of the small fringe group who say Jesus was entirely mythical.
A police detective is not a historian or scholar of ancient manuscripts. I doubt he even knows a word of Koine Greek, does he? So he doesn’t even enter the discussion. I could just as easily say my plumber thinks Jesus was a myth, it’d be as relevant.
I accept that. I also accept that the early Muslims believed Muhammad spoke with God and flew up to heaven on a flying horse with the head of a woman, and that modern day Scientologists believe the story of Xenu and the Galactic Confederacy.
So what?
