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.
Haredi Judaism
Haredi Judaism ( ', ; also spelled "Charedi", plural "Haredim" or "Charedim") is a broad spectrum of groups within Orthodox Judaism, all characterized by a rejection of modern secular culture. Its members are often referred to as strictly Orthodox or ultra-Orthodox in English, although the term "ultra-Orthodox" is considered pejorative by many of its adherents. Haredim regard themselves as the most religiously authentic group of Jews, although this claim is contested by other streams.
