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.
Pharisees
During the Second Temple era, when Jews were divided into sects, the Pharisees were one sect among many, and partisan. Each sect claimed a monopoly on the truth, and discouraged marriage between members of different sects. Members of different sects did, however, argue with one another over the correctness of their respective interpretations, although there is no significant, reliable record of such debates between sects. After the destruction of the Second Temple, these sectarian divisions ended. The Rabbis avoided the term "Pharisee," 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", a prayer which in part exclaims, "Praised are You O Lord, who breaks enemies and defeats the wicked," 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. The Pharisaic commitment to scholarly debate as a value in and of itself, rather than merely a byproduct of sectarianism, emerged as a defining feature of Rabbinic Judaism.
