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.
Reform Judaism
The next in size, by a wide margin, are the two British WUPJ-affiliates. In 2010, the Movement for Reform Judaism and Liberal Judaism respectively had 16,125 and 7,197 member households in 45 and 39 communities, or 19.4% and 8.7% of British Jews registered at a synagogue. Other member organizations are based in forty countries around the world. They include the Union progressiver Juden in Deutschland, which had some 4,500 members in 2010 and incorporates 25 congregations, one in Austria; the Nederlands Verbond voor Progressief Jodendom, with 3,500 affiliates in 10 communities; the 13 Liberal synagogues in France; the Israel Movement for Reform and Progressive Judaism (5,000 members in 2000, 35 communities); the Movement for Progressive Judaism (Движение прогрессивного Иудаизма) in the CIS and Baltic States, with 61 affiliates in Russia, Ukraine and Belarus and several thousands of regular constituents; and many other, smaller ones.
