Conservative Judaism is a Jewish religious movement that regards the authority of Jewish law and tradition as emanating primarily from the assent of the people through the generations, more than from divine revelation. It therefore views Jewish law, or halakha, as both binding and subject to historical development. The conservative rabbinate employs modern historical-critical research, rather than only traditional methods and sources, and lends great weight to its constituency, when determining its stance on matters of practice. The movement considers its approach as the authentic and most appropriate continuation of halakhic discourse, maintaining both fealty to received forms and flexibility in their interpretation. It also eschews strict theological definitions, lacking a consensus in matters of faith and allowing great pluralism.
Orthodox Judaism is the collective term for the traditionalist branches of contemporary Judaism. Theologically, it is chiefly defined by regarding the Torah, both Written and Oral, as revealed by God to Moses on Mount Sinai and faithfully transmitted ever since.
Reform Judaism, also known as Liberal Judaism or Progressive Judaism, is a Jewish denomination that emphasizes the evolving nature of Judaism, the superiority of its ethical aspects to its ceremonial ones, and belief in a continuous search for truth and knowledge, which is closely intertwined with human reason and not limited to the theophany at Mount Sinai. A highly liberal strand of Judaism, it is characterized by lessened stress on ritual and personal observance, regarding halakha as non-binding and the individual Jew as autonomous, and great openness to external influences and progressive values. The fundamental difference is the approach to Torah and the implications of that approach. The Orthodox believe that it comes directly from God and so cannot be changed. Since its founding in Germany in the 1800s, Reform Judaism has adapted prayer liturgy into a more flexible understanding of Judaism.
The relationships between the various denominations of American Judaism are complex and include a range of trends from the conciliatory and welcoming to hostile and antagonistic.
Modern Orthodox Judaism is a movement within Orthodox Judaism that attempts to synthesize Jewish values and the observance of Jewish law with the modern world.
Liberal Judaism is one of the two WUPJ-affiliated denominations in the United Kingdom founded by Claude Montefiore. It is smaller and more radical in comparison with the other one, the Movement for Reform Judaism. It is considered ideologically closer to American Reform Judaism than it is to the British Reform movement. As of 2010 it was the fourth largest Jewish religious group in Britain, with 8.7% of synagogue-member households.
The machzor is the prayer book which is used by Jews on the High Holy Days of Rosh Hashanah and Yom Kippur. Many Jews also make use of specialized machzorim on the three pilgrimage festivals of Passover, Shavuot, and Sukkot. The machzor is a specialized form of the siddur, which is generally intended for use in weekday and Shabbat services.
Jewish religious movements, sometimes called "denominations", include diverse groups within Judaism which have developed among Jews from ancient times. Today in the west, the most prominent divisions are between traditionalist Orthodox movements and modernist movements such as Reform Judaism originating in late 18th century Europe, Conservative originating in 19th century Europe, and smaller others.
A mechitza in Judaism, is a partition, particularly one that is used to separate men and women.
Neologs are one of the two large communal organizations among Hungarian Jewry. Socially, the liberal and modernist Neologs had been more inclined toward integration into Hungarian society since the Era of Emancipation in the 19th century. This was their main feature, and they were largely the representative body of urban, assimilated middle- and upper-class Jews. Religiously, the Neolog rabbinate was influenced primarily by Zecharias Frankel's Positive-Historical School, from which Conservative Judaism evolved as well, although the formal rabbinical leadership had little sway over the largely assimilationist communal establishment and congregants. Their rift with the traditionalist and conservative Orthodox Jews was institutionalized following the 1868–1869 Hungarian Jewish Congress, and they became a de facto separate denomination. The Neologs remained organizationally independent in those territories ceded under the terms of the 1920 Treaty of Trianon, and are still the largest group among Hungary's Jews.
The Orthodox Union is one of the largest Orthodox Jewish organizations in the United States. Founded in 1898, the OU supports a network of synagogues, youth programs, Jewish and Religious Zionist advocacy programs, programs for the disabled, localized religious study programs, and international units with locations in Israel and formerly in Ukraine. The OU maintains a kosher certification service, whose circled-U hechsher symbol, U+24CAⓊ, is found on the labels of many kosher commercial and consumer food products.
Reform Judaism is one of the two World Union for Progressive Judaism–affiliated denominations in the United Kingdom. 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. On 17 April 2023, Reform Judaism and Liberal Judaism announced their intention to merge as one single unified progressive Jewish movement. The new movement, which may be called Progressive Judaism, will represent about 30% of British Jewry who are affiliated to synagogues.
The National Council of Young Israel (NCYI) or Young Israel, is a synagogue-based Orthodox Judaism organization in the United States with a network of affiliated "Young Israel" synagogues. Young Israel was founded in 1912, in its earliest form, by a group of 15 young Jews on the Lower East Side of Manhattan. Their goal was to make Orthodox Judaism more relevant to young Americanized Jews at a time when a significant Jewish education was rare, and most Orthodox institutions were Yiddish-speaking and oriented to an older, European Jewish demographic.
The Union for Traditional Judaism, founded in 1984, is a traditional, Halakhic Jewish outreach and communal service organization. It initially called itself "The Union for Traditional Conservative Judaism" but dropped "Conservative" from its title when it broke with the Conservative movement. In 1985 Rabbi Ronald D. Price was tapped to lead the organization as executive director and later as Executive Vice President. He served in that capacity for 26 years until his retirement in 2011. He was succeeded by Rabbi David Bauman and then Rabbi Gerald Sussman who is currently (2018) the executive director. In 1988 after attempting to affect change within Conservative Judaism, the UTJ membership voted to drop the word 'Conservative' from its title. Following a two-year period of negotiations, the Rabbinic Fellowship of the UTJ absorbed a modern Orthodox rabbinic organization, the Fellowship of Traditional Orthodox Rabbis. The merged rabbinic body is known today as MORASHAH. Some of the UTJ leaders at various times called themselves Conservative, Modern Orthodox or trans-denominational. The UTJ's Institute of Traditional Judaism (ITJ) granted semikhah to a number of rabbis, though as of 2018 there are no current semikhah students. The UTJ's Panel of Halakhic Inquiry has published three volumes of responsa titled "Tomeikh kaHalakhah." The UTJ produced the educational curriculum "Taking the MTV Challenge—Media and Torah Values" designed to provide high-school students with tools to respond to the electronic media. The UTJ is often viewed as representing a denomination or inhabiting an ideological space between Conservative and Orthodox Judaism.

He is the founder of Yeshivat Chovevei Torah for men and Yeshivat Maharat for women, rabbinical seminaries that are tied to Open Orthodoxy, a breakaway movement that Weiss originated, which is to the left of Modern Orthodox Judaism and to the right of Conservative Judaism. He is co-founder of the International Rabbinic Fellowship, a rabbinical association that is a liberal alternative to the Orthodox Rabbinical Council of America, and founder of the grassroots organization Coalition for Jewish Concerns – Amcha.
The Liberal Jewish Synagogue, or LJS, is a house of prayer in St John's Wood, London, founded in 1911. It is the oldest and largest member of Britain's Liberal Judaism, a constituent member of the World Union for Progressive Judaism.
Open Orthodox Judaism is a Jewish religious movement with increased emphasis on intellectual openness and a more expansive role for women. The term was coined in 1997 by Avi Weiss, who views halakha as permitting more flexibility than the normal practices of Orthodox Judaism.
Beth HaMedrosh Hagodol-Beth Joseph, known locally as BMH-BJ or simply BMH, and for a period after 2012 also known as The Denver Synagogue, is a Modern Orthodox, Zionist synagogue in Denver, Colorado.

The South African Union for Progressive Judaism (SAUPJ) is an affiliate of the World Union for Progressive Judaism and supports 11 progressive congregations. The SAUJP estimates that it represents around 6,000 South African Jews and around 10 per cent of the overall Jewish population residing in South Africa. In 2020 a study by the Institute for Jewish Policy Research showed that 12% identified as Progressive and that in relative terms the progressive strands are increasing.
