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.
Sadducees
The Sadducees (; Hebrew: "Ṣĕdûqîm") were a sect or group of Jews that was active in Judea during the Second Temple period, starting from the second century BCE through the destruction of the Temple in 70 CE. The sect was identified by Josephus with the upper social and economic echelon of Judean society. As a whole, the sect fulfilled various political, social, and religious roles, including maintaining the Temple. The Sadducees are often compared to other contemporaneous sects, including the Pharisees and the Essenes. Their sect is believed to have become extinct some time after the destruction of Herod's Temple in Jerusalem in 70 CE, but it has been speculated that the later Karaites may have had some roots in—or connections with—Sadducaic views.
