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.
Zionism
Many Haredi Orthodox organizations oppose Zionism; they view Zionism as a secular movement. They reject nationalism as a doctrine and consider Judaism to be first and foremost a religion that is not dependent on a state. However, some Haredi movements (such as Shas since 2010) do openly affiliate with the Zionist movement.
