If you read that link to Jewish~Christianity, which is your first "Christianity", there was always this Darwinic expression thru religion that was characterized by a central authority, for maintaining tribal unity ,survival & identity purposes. Wolves, sea lions & penguins, birds, bats & bees do no less in nature, migrations to protected ground, for safety in nesting & procreation, familiar pathways to sacred hunting grounds for water &feeding, sustainence/survival of the body, for the human this would be the consecrated city for the Temple, the "Holy Land".
The Jews were an expression of this archaic self imposed constraint, where only by a journey to the Temple could true atonement come,this was the LAW ! That Temple was huge, like forty football fields in its interior? The priest system acted in every capacity, from foreign exchange, taxation, politics & the revenues from sacrifice. (Mohammed did no less, its instinctual/nature, but he relaxed it somewhat)
Emergence of Rabbinic Judaism and Christianity, The separation of Christianity from Judaism was a process, not an event.

At the time of the Destruction of the Second Temple, Judaism was divided into antagonistic factions. The main camps were the Pharisees, Saducees, and Zealots, but also included other less influential sects. This led to further unrest, and the 1st century BC and 1st century AD saw a number of charismatic religious leaders, contributing to what would become the Mishnah of Rabbinic Judaism, including Yochanan ben Zakai and Hanina Ben Dosa.
According to most scholars, the followers of Jesus composed principally apocalyptic Jewish sects during the late Second Temple period of the 1st century. Some Early Christian groups were strictly Jewish, such as the Ebionites and the early church leaders in Jerusalem, collectively called Jewish Christians. During this period, they were led by James the Just. Paul of Tarsus, commonly known as Saint Paul, persecuted the early Jewish Christians, such as Saint Stephen, then converted and adopted the title of "Apostle to the Gentiles" and started proselytizing among the Gentiles. He persuaded the leaders of the Jerusalem Church to allow Gentile converts exemption from most Jewish commandments at the Council of Jerusalem, which may parallel Noahide Law in Rabbinic Judaism.
Most historians agree that Jesus or his followers established a new Jewish sect, one that attracted both Jewish and Gentile converts. Historians continue to debate the precise moment when Christianity established itself as a new religion, apart and distinct from Judaism. Some scholars view Christians as much as Pharisees as being competing movements within Judaism that decisively broke only after the Bar Kokhba's revolt, when the successors of the Pharisees claimed hegemony over all Judaism, and – at least from the Jewish perspective – Christianity emerged as a new religion. Some Christians were still part of the Jewish community up until the time of the Bar Kochba revolt in the 130s, see also Jewish Christians.
According to historian Shaye J. D. Cohen,
The separation of Christianity from Judaism was a process, not an event. The essential part of this process was that the church was becoming more and more gentile, and less and less Jewish, but the separation manifested itself in different ways in each local community where Jews and Christians dwelt together. In some places, the Jews expelled the Christians; in other, the Christians left of their own accord. [22]According to Cohen, this process ended in 70 CE, after the great revolt, when various Jewish sects disappeared and Pharisaic Judaism evolved into Rabbinic Judaism, and Christianity emerged as a distinct religion. [23]
The Great Revolt and the Destruction of the Temple[ edit] Main article: First Jewish–Roman War By 66 CE Jewish discontent with Rome had escalated. At first, the priests tried to suppress rebellion, even calling upon the Pharisees for help. After the Roman garrison failed to stop Hellenists from desecrating a synagogue in Caesarea, however, the high priest suspended payment of tribute, inaugurating the Great Jewish Revolt.
After a Jewish revolt against Roman rule in 66 CE, the Romans all but destroyed Jerusalem. Following a second revolt, Jews were not allowed to enter the city of Jerusalem except for the day of Tisha B'Av and most Jewish worship was forbidden by Rome[ citation needed]. Rome instituted the Fiscus Judaicus, those who paid the tax were allowed to continue Jewish practices. Following the destruction of Jerusalem and the expulsion of the Jews, Jewish worship stopped being centrally organized around the Temple, prayer took the place of sacrifice, and worship was rebuilt around rabbis who acted as teachers and leaders of individual communities (see Jewish diaspora and Council of Jamnia).
In 70 the Temple was destroyed. The destruction of the Second Temple was a profoundly traumatic experience for the Jews, who were now confronted with difficult and far-reaching questions: [24]
- How to achieve atonement without the Temple?
- How to explain the disastrous outcome of the rebellion?
- How to live in the post-Temple, Romanized world?
- How to connect present and past traditions?
How people answered these questioned depended largely on their position prior to the revolt. But the destruction of the Second Temple by the Romans not only put an end to the revolt, it marked the end of an era. Revolutionaries like the Zealots had been crushed by the Romans, and had little credibility (the last Zealots died at Masada in 73). The Sadducees, whose teachings were so closely connected to the Temple cult, disappeared. The Essenes also vanished, perhaps because their teachings so diverged from the issues of the times that the destruction of the Second Temple was of no consequence to them; precisely for this reason, they were of little consequence to the vast majority of Jews.
Two organized groups remained: the Early Christians, and Pharisees. Some scholars, such as Daniel Boyarin and Paula Fredricksen, suggest that it was at this time, when Christians and Pharisees were competing for leadership of the Jewish people, that accounts of debates between Jesus and the apostles, debates with Pharisees, and anti-Pharisaic passages, were written and incorporated into the New Testament. |
