Zico remonstrates: People will always argue over doctrine, will always have divisions, and will always use God to support them in war, and would do so no matter what the bible, or any holy book that's claimed to be from God, says.
I think I understand where you are coming from on this. I appreciate your taking the time to go into detail about it. I'm more confused than ever now, however.
I'm tempted to use bullet points to say why.
1.The attribution of Apostle's names to Gospels is not much more than an affectation to lend authority to the contents. (The Gospel according to....)
2.The early gospels are stripped of much of the super-hero Jesus descriptions (Mark) which gather impetus as the years pass until John gives us Super-Jesus who is Divine. This makes me suspicious of exaggeration.
3.In important matters (like life and death!) the details are important. In a court case, the fate of persons and property lie in the balance of the telling of the truth, the whole truth and nothing but the truth. What you describe as the testimony of men (and their contradicting views) pretty much disables the details.
4.The only explanation for the same religion (Christianity) having so many factions, divisions, sects and cults using the same Gospel accounts is this very lack of rigor in matching testimonies!
5.The Roman empire was certainly bureaucratic. Thousands of writers, documents and official texts and observations, memoirs, rumours and myths circulated freely without so much as a mundane mention of a super Jew miracle worker who raised the dead, walked on water, made water into wine, healed the sick and restored sight to the blind, etc. and this seems impossible to explain to me.
6.There probably was somebody or other represented by the character of Jesus who said and did things considered to be remarkable to the extent his fans didn't want his death to be ordinary. Elvis and JFK are good examples of such persons. Elvis still is sighted here and there and J.F.K. just had to be the victim of outrageous conspiracies involving the C.I.A., the Mafia, the Cubans, the K.G.B. and the F.B.I., but, certainly not one disaffected wacko named Lee Oswald. See what I mean?
