Orthodox Judaism in the context of "Haredi Judaism"

Jewish religious movements, sometimes called "denominations", include diverse groups within Judaism which have developed among Jews from ancient times. Samaritans are also considered ethnic Jews by the Chief Rabbinate of Israel, although they are frequently classified by experts as a sister Hebrew people, who practice a separate branch of Israelite religion. Today in the West, the most prominent divisions are between traditionalist Orthodox movements (including Haredi ultratraditionalist and Modern Orthodox branches) and modernist movements such as Reform Judaism originating in late 18th century Europe, Conservative (Masorti) originating in 19th century Europe, and other smaller ones, including the Reconstructionist and Renewal movements which emerged later in the 20th century in the United States.

In Israel, variation is moderately similar, differing from the West in having roots in the Old Yishuv and pre-to-early-state Yemenite infusion, among other influences. For statistical and practical purposes, the distinctions there are based upon a person's attitude to religion. Most Jewish Israelis classify themselves as "secular" (hiloni), "traditional" (masortim), "religious" (dati) or ultra-religious (haredi).

A religious denomination is a subgroup within a religion that operates under a common name and tradition, among other activities.The term refers to the various Christian denominations (for example, non-Chalcedonian, Eastern Orthodox, Catholic, and the branches of Protestantism, such as Lutheranism). It is also used to describe the five major branches of Judaism (Karaite Judaism, Orthodox, Conservative, Reform, and Reconstructionist). Within Islam, it can refer to the branches or sects (such as Sunni and Shia), as well as their various subdivisions, such as sub-sects, schools of jurisprudence, schools of theology and religious movements.

The world's largest religious denomination is the Sunni Islam.

Religious Jews are Jews who practice and observe Judaism. They may be affiliated with:

• Karaite Judaism
• Conservative Judaism
• Masorti Judaism
• Orthodox Judaism
  • Hasidic Judaism
  • Religious Zionism
  • Haredi Judaism
  • Modern Orthodox Judaism
• Reconstructionist Judaism
• Reform Judaism
• Jewish Renewal
• Non-Ashkenazi branches, such as Sephardic Judaism

A mikveh or Mikvah (Hebrew: מִקְוֶה / מקווה, Modern: mīqve, Tiberian: mīqwe, pl. mikva'ot, mikvot, or (Ashkenazic) mikves, lit. 'a collection') is a bath used for ritual immersion in Judaism to achieve ritual purity.

In Orthodox Judaism, these regulations are steadfastly adhered to; consequently, the mikveh is central to an Orthodox Jewish community. Conservative Judaism also formally holds to the regulations. The existence of a mikveh is considered so important that, according to halacha, a Jewish community is required to construct a kosher mikveh even before building a synagogue, and must go to the extreme of selling Torah scrolls, or even a synagogue if necessary, to provide funding for its construction.

A rabbi (/ˈræbaɪ/ ; Hebrew: רַבִּי, romanized: rabbī, IPA: [ʁəbːi]) is a spiritual leader or religious teacher in Judaism. A person becomes a rabbi by being ordained by another rabbi—known as semikhah—following a course of study of Jewish history and texts, including the Tanakh, Midrash, Mishnah, Tosefta, Talmud, Halakha, and rabbinic commentaries thereon. The basic form of the rabbi developed between the Second Temple (167 BCE–73 CE)—being heavily influenced by the Pharisees—and Rabbinic periods (70–640 CE), when learned teachers—overlapping with the Tannaim, Amoraim, Savoraim, and early Geonim—assembled to codify Judaism's written and oral laws. The title "rabbi" was first used in the first century CE. In more recent centuries, the duties of a rabbi became increasingly influenced by the duties of the Protestant Christian minister, hence the title "pulpit rabbis." Further, in 19th-century Germany and the United States, rabbinical activities such as delivering sermons, pastoral counseling, and representing the community to the outside all increased in importance.

Within the various Jewish denominations, there are different requirements for rabbinic ordination, and differences in opinion regarding who is recognized as a rabbi. Non-Orthodox movements, including Conservative Judaism, Reform Judaism, Reconstructionist Judaism, and Jewish Renewal, have set their requirements for semikhah based on what they consider halakhic reasons (as in Conservative Judaism) and ethical reasons (as in Reform and Reconstructionist) Judaism).

"Who is a Jew?" (Hebrew: מיהו יהודי, romanized: mihu yehudi, pronounced [ˈmi(h)u je(h)uˈdi]), is a basic question about Jewish identity and considerations of Jewish self-identification. The question pertains to ideas about Jewish personhood, which have cultural, ethnic, religious, political, genealogical, and personal dimensions. Orthodox Judaism and Conservative Judaism follow Jewish law (halakha), deeming people to be Jewish if their mothers are Jewish or if they underwent a halakhic conversion. Reform Judaism and Reconstructionist Judaism accept both matrilineal and patrilineal descent as well as conversion. Karaite Judaism predominantly follows patrilineal descent as well as conversion.

Jewish identity is also commonly defined through ethnicity. Opinion polls have suggested that the majority of modern Jews see being Jewish as predominantly a matter of ancestry and culture, rather than religion.

Modern Orthodox Judaism (also Modern Orthodox or Modern Orthodoxy) is a movement within Orthodox Judaism that attempts to synthesize Jewish values and the observance of Jewish law with the modern world.

Modern Orthodoxy draws on several teachings and philosophies, and thus assumes various forms. In the United States, and generally in the Western world, Centrist Orthodoxy underpinned by the philosophy of Torah Umadda ("Torah and secular knowledge") is prevalent. In Israel, Modern Orthodoxy is dominated by Religious Zionism; however, although not identical, these movements share many of the same values and many of the same adherents.

Reconstructionist Judaism is a Jewish movement based on the concepts developed by Rabbi Mordecai Kaplan (1881–1983)—namely, that Judaism is a progressively evolving civilization rather than just a religion. The movement originated as a semi-organized stream within Conservative Judaism, developed between the late 1920s and the 1940s before seceding in 1955, and established a rabbinical college in 1967. Reconstructionist Judaism is recognized by many scholars as one of the five major streams of Judaism in America alongside Orthodox, Conservative, Reform, and Humanistic.

There is substantial theological diversity within the movement. Halakha (Jewish law) is not considered normative or binding, but rather serves as the basis for the ongoing evolution of meaningful Jewish practice. In contrast with the Reform movement's stance during the time he was writing, Kaplan believed that "Jewish life [is] meaningless without Jewish law." One of the planks he wrote for the proto-Reconstructionist Society for the Jewish Renaissance stated, "We accept the halakha, which is rooted in the Talmud, as the norm of Jewish life, availing ourselves, at the same time, of the method implicit therein to interpret and develop the body of Jewish Law by the actual conditions and spiritual needs of modern life." The movement also emphasizes positive views toward modernity. It has an approach to Jewish customs that aims toward communal decision-making through a process of education and distillation of values from traditional Jewish sources.
