Judaism
Around the 1st century CE, there were several small Jewish sects: the Pharisees, Sadducees, Zealots, Essenes, and Christians. After the destruction of the Second Temple in 70 CE, these sects vanished. Christianity survived, but by breaking with Judaism and becoming a separate religion; the Pharisees survived but in the form of Rabbinic Judaism (today, known simply as "Judaism"). The Sadducees rejected the divine inspiration of the Prophets and the Writings, relying only on the Torah as divinely inspired. Consequently, a number of other core tenets of the Pharisees' belief system (which became the basis for modern Judaism), were also dismissed by the Sadducees. (The Samaritans practiced a similar religion, which is traditionally considered separate from Judaism.)
Movement for Reform Judaism
The Movement for Reform Judaism (until 2005, known as Reform Synagogues of Great Britain) is one of the two World Union for Progressive Judaism-affiliated denominations in Britain. Reform is relatively traditional in comparison with its smaller counterpart, Liberal Judaism, though it does not regard Jewish law as binding. As of 2010, it was the second largest Jewish religious group in the United Kingdom, with 19.4% of synagogue-member households.
