Jesus in the Talmud
In the first few centuries CE, there were many sects of Judaism (such as Pharisees, Essenes, and Sadducees) each claiming to be the correct faith. Some scholars treat Christianity, during that era, referred to as Early Christianity, as simply one of many sects of Judaism. Some sects wrote polemics advocating their position, and occasionally disparaging rival sects. Some scholars view the depictions of Jesus in the Talmud as a manifestation of those inter-sect rivalries – thus the depictions can be read as polemics by the rabbinic authors of the Talmud which indirectly criticized the rival sect (Christianity), which was growing and becoming more dominant.
Historical background of the New Testament
Although the Rabbis traced their origins to the Pharisees, Rabbinic Judaism nevertheless involved a radical repudiation of certain elements of Phariseism – elements that were basic to Second Temple Judaism. The Pharisees had been partisan. Members of different sects argued with one another over the correctness of their respective interpretations, see also Hillel and Shammai. After the destruction of the Second Temple, these sectarian divisions ended. The term "Pharisee" was no longer used, perhaps because it was a term more often used by non-Pharisees, but also because the term was explicitly sectarian. The Rabbis claimed leadership over all Jews, and added to the Amidah the "birkat haMinim" (see Council of Jamnia), a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the arrogant," and which is understood as a rejection of sectarians and sectarianism. This shift by no means resolved conflicts over the interpretation of the Torah; rather, it relocated debates between sects to debates within Rabbinic Judaism.
