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.
Religious anti-Zionism
Today, the main Jewish theological opposition to Zionism stems from the Satmar Hasidim, which has more than 150,000 adherents worldwide. Even more strongly opposed to Zionism is the small Haredi Jewish organization known as Neturei Karta., which has less than 5,000 members, almost all of whom live in Israel and Palestine. According to "The Guardian", "[e]ven among Charedi, or ultra-Orthodox circles, the Neturei Karta are regarded as a wild fringe".)
