This old man doesn't hate you... I just want to point out that you are in danger of becoming dogmatic.
As a dog lover I'm proud to be called dogmatic
You're right, Jesus was very much a Jew and I am convinced he thought of himself as a Jew right to the end (which if one is a true believer is never, but I digress).
However, what's all this about Jesus not being a christain? How could he not be a christian if from him eminated the teaching that makes one a christian.
Ah, but did it really, truly? Jesus was an Essene priest. What marked him out as divine and the others 'also-rans'? John the Baptist was almost certainly the leader of the Essenes and He and Jesus had disputes that were recorded in the DSS. Both at one time were thought to be the Messiah.
I'd agree if you meant that Jesus probably didn't intend to create a new religion, but rather wanted to "clean up" and reinvigorate Jewish life as it was then.
Bingo. Dead centre on target. The Essenes were much favoured by Herod the Great. Through the Figtree and the Vine organisations set up to keep Diaspora jews in the faith, money was rolling in. When the Essene missionaries recruited non-jews to a simplified (and gentler) set of rules the money started pouring in. Again its in the DSS.
The label "christian", in that case, would have had no meaning while he was roaming the countryside.
Jesus spent much of his life in religious institutions and wasn't well travelled (for those days) until he became much older. It is known that he went to Rome and Crete.
Afterall, as you well know, the word come from cristos, the annointed one. How people interpreted annointed then and now might be different. However, there's no question his message set him apart from the average Jew at the time, and so he and his followers merited some sort of label, hence christian, follower of the annointed one, works just fine.
