Christianity teaches the Holy Writ was divinely inspired. I can't prove it but neither can you disprove it.
Like all great works of art. The problem is what one's view is on divine. Access to the the collective unconscious or to good weed etc..
One thing is for certain, the prophecies in the bible are contrived but that does not deny their genius etc..

They had no answer to my question: Are the words 'Eat my body and drink my blood' therefore an appeal to cannibalism?
I think that's the way with all fundamentalist sects these day. Looking for scientific proof to legitimize their dogmatic power that is fading in modernity. They can't just win us over with gun powder tricks or brute force. So they bore the shiiite out of us with crappy documentaries looking for Noah's Ark or the Holy Shroud etc. I think the church is doomed to fail in a democratic modern world, but then again, there's the bible belt of Europe and the hill billy states of the USA who are determined undo democracy's evolution and get back to the good old days when men were men and Pansie was the name of a flower.
Given that you know the bible so well, perhaps you can tell us where we can find his thoughts about homosexuality.
The bible was written over several centuries and Jesus was only "interpreted" by later writers; he wrote nothing. Better off reading Plato, St Augustine or something, they managed to find some ink. Maybe this will answer your question..
