Sorry but I don't agree with you. But before continuing, let me make it clear that I am not in any way referring to the divinity claims nor some other aspects found within the gospels. IOW, I'm strictly referring to what appears to me to be happening in regards to Jesus' take on the Law.
The northern area of eretz Israel was quite well know for it's "liberalness', and this was even made more so with the Greek and Roman influences. Jesus' idea of the Law reflecting "the love of God, love of man" concept was hardly new, and Greek influences especially seemingly had an influence of making some elements of Pharisees to be less parochial in their worldview.
Now, what else needs to be considered is the fact that archaeologists believe there were at least four different Pharisee groups and probably even more. And then there's different personal opinions, of course, and to a large extent this is "kosher" as well, and even though I am far from certain Jesus had any affiliation to any specific Pharisee group, nevertheless he was operating out of the general liberal Pharisee paradigm.
BTW, while I'm at it, Martin Buber also mentions this as well, placing Jesus smack-dab within the movement, until both the claims of divinity and the "must believe in order to be 'saved'" changed "the Way" from being a Jewish movement into a separate religion.
