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.
Jewish education
The Conservative movement has USY - United Synagogue Youth. The Modern Orthodox movement has NCSY - formerly National Conference of Synagogue Youth. BBYO is a non-denominational group, though most Jews associate it with the Conservative or Reform movements. The North American Federation of Temple Youth, known as NFTY, is the organized youth movement of Reform Judaism in North America. Funded and supported by the Union for Reform Judaism, NFTY exists to supplement and support Reform youth groups at the synagogue level. About 750 local youth groups affiliate themselves with the organization, comprising over 8,500 youth members.
