Yes, exactly!
The question is this: were they unreasonable in this expectation? David argues not. There were certain, clear tests that Jesus failed to fulfill.
Yes, this happened primarily at the Council of Jamnia in the late 1st century when the Hebrew Bible canon was decided upon.
Modern scholarship dismisses the notion of a conference at Yavneh in 90 c.e. in which a definitive decision was made as to the codification of the Tanach. As to the claims that at this same conference changes in texts or interpretations were made in the Tanach due to Christianity, this presumes that Jews in someway cared about Christian beliefs or were somehow threatened by them. Since Judaism cannot accept the notion of rejection of the Torah or a human as God no interpretation had to be changed nor any text. Presumably Christianity also doesn’t feel called upon to make changes in their scriptures based on the basis of other religions. Furthermore, it should be understood that at this time Christianity was a small group who unlike the Jews did not enjoy the privi lege of not participating in state religious services and were being fed by the Romans to the lions. It will be more than two centuries before Christianity will gain its position of strength and the emperor will convert.
Concerning your statements about changes in Judaism due to the destruction of the Temple, the trauma was great but the religious changes were actually quite less then those indicated in your post. Already at this time a wide Jewish diaspora existed throughout the Roman Empire (Jews making up some ten per cent of the Empire’s population). The necessary infrastructure of carrying out religious services in the synagogue as opposed around the Temple were well established as was the basis for Rabbinical Judaism. As I pointed out previously, one can hardly equate Torah with those particular laws dealing with Temple worship.
The rejection by Christianity of the Torah was a necessity due to the quest for universality by Christianity and the level of the general population of the time. The Jews covenant with God is two fold, first the ability to be able conceive of a singular omnipresent God not only as an entity separate from humanity but without the crutch of needing to be aided by giving God a tangible form. The second part of the covenant is Torah where Law is not only given Devine status but religion now deals not only with man’s relationship to God but man’s relationship to man.
Torah had to be taught from father to son, Judaism’s followers not only had to be able to conceive of God in abstract intangible form they had to be able to understand legal nuances as to why in one case they would be exempt from responsibility if the ox in their care gored a neighbour but in other cases they would be liable. Judaism was and is an intellectual religion. It required universal male literacy to pass on Torah from generation to generation and two thousand years ago Jews were almost alone in this ability.
Since the general population was not literate and since Christianity sought to be universal to all people without regard to an adherents educational or intellectual abilities it by necessity had to reject Torah. It had to become a dogmatic religion as opposed to an intellectual one where distinct clear rules of faith could be learned by rote and with an hierarchy to decide these rules. What remained of Torah in Christianity is merely a set of basic Jewish ethics such as love thy neighbour as thyself ( these ethics are referred to by Christians as Judeo-Christian ethics).
The real growth of Christianity and its achievement of universality came about with its willingness to gradually reject the other side of the covenant, from a singular intangible God the figure of Yehoshua Bar Yosef became a variation of the classic pagan story (Mithra, Hercules etc.) of the Divine father and human mother whose child comes down to earth, has a special birth with special signs(non of the stories ever describe childhood), performs wondrous acts, gives his life for mankind’s salvation and is resurrected back to his father.
In short, God did not pull a fast one on the Jews. Christianity claims a new covenant in place of the old. However, this new covenant is the antithesis of the Jewish covenant. One does not lead to the other. One may only claim, with its ramifications, that either there never was a covenant between the Jews and God or that such a covenant is still in existence. That God would make a covenant with the Jews that would require them to reject that very covenant and accept its antithesis is something that is beyond my ken to grasp.
