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.
Origins of Rabbinic Judaism
Judaism at this time 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. The ministry of Jesus, according to the account of the Gospels, falls into this pattern of sectarian "preachers" or "teachers" with devoted "disciples" (derived from the Greek word for "students").
