Well, I hate to say this (considering your screen name) but you have been deceived.
Very few scholars and historians would agree with your position and there is NO CREDIBLE evidence to support your claim. The only folks who would be in your camp, would be the most conservative evangelical christian scholars.
The followers of Jesus, were illiterate and not only couldn't write, but they couldn't read either and they spoke aramaic. The NT, was written in Greek and decades (I repeat decades) after Jesus died. Yet, you claim they were keeping copious notes of Jesus all along.
Do yourself a favor, and do some OBJECTIVE review of the historical and scholarly aspect of the NT. You have obviously latched onto the opinions of a fringe group of scholars to confirm what you want to believe, without credible evidence.
Lastly, if you are of the position that Matthew, Mark, Luke and John were the true authors of the 4 gospels, you are really out over your skis. Even most conservative scholars will acknowledge, the authors of the 4 gospels were anonymous and were written decades after Jesus died.
