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.)
Religion in Israel
Conservative Judaism and Reform Judaism are represented among Israeli Jews. According to The Israel Democracy Institute, as of 2013, approximately 8 percent of Israel’s Jewish population "identified" with Reform and Conservative Judaism, a study by Pew Research Center showed 5% did, while a Midgam survey showed that one third "especially identified with Progressive Judaism", almost as many as those who especially identify with Orthodox Judaism. The Chief Rabbinate strongly opposes the Reform and Conservative movements, saying they are "uprooting Judaism", that they cause assimilation and that they have “no connection” to authentic Judaism. The chief rabbinate's view does not reflect the majority viewpoint of Israeli Jews, however. A survey of Israeli Jews published in May 2016 showed that 72 percent of respondents said they disagreed with the Haredi assertions that Reform Jews are not really Jewish. The survey also showed that a third of Israeli Jews "identify" with progressive (Reform or Conservative) Judaism and almost two thirds agree that Reform Judaism should have equal rights in Israel with Orthodox Judaism. The report was organized by the Israel Movement for Reform and Progressive Judaism ahead of its 52nd biennial conference.
