You know that I do respect your opinion... yes I see you do think Jesus did exist...
I can say in my studies I have to believe there were many Jesus'. I have come to believe it was a title.... just as many Mary's and Ann's.
As far as all the contributations to what this one did... I'm not so sure... Raising Lazurs... I think it was a symbolic death... One the Essenes exhibited many times.
Belief... no... it's more like probability.
