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.)
Young Judaea
Founded in 1909, Young Judaea is a peer-led youth movement. Its programs include youth clubs, conventions, camps and Israel programs with an emphasis on social action and Jewish identity. Young Judaea has 15 regions in the United States and is affiliated with the Federation of Zionist Youth (United Kingdom) and Tzofim (Israel). The age levels are "Ofarim" (Hebrew for "fawns;" grades 2–5), "Tsofim" ("scouts," grades 6–7), and "Bogrim" ("elders," grades 8–12). Young Judaea's university arm was formerly called HaMagshimim, meaning "the fulfillers"), now college programs focus primarily on volunteering and interning in Israel as well as Birthright trips.
