Conservative Judaism

• 1. Introduction

  ›

  Conservative Judaism sits at a crossroads that has puzzled, frustrated, and inspired its followers for well over a century. It claims to be both bound by Jewish law and free to evolve with history. It calls itself the authentic heir of ancient tradition while employing the same modern historical-critical tools that skeptics use to dissect scripture. And for decades, it was the single largest Jewish religious movement in the United States, drawing over 40 per cent of American Jews at its peak in the 1970s. By 2013, that figure had fallen to roughly 18 per cent.

  The movement traces its intellectual roots to a Prague-born rabbi named Zecharias Frankel, who in December 1843 launched a magazine to argue for what he called a positive-historical approach to Judaism. That phrase would define a middle path between radical Reform and hardline Orthodoxy for generations. Yet for most of its existence, Conservative Judaism resisted putting its beliefs on paper. It was not until 1985 that the Jewish Theological Seminary of America opened its first course on Conservative theology. Three years later, in 1988, the movement issued its first real statement of principles, called Emet ve-Emunah.

  Today, Conservative Judaism is the third-largest Jewish religious movement worldwide, estimated at close to 1.1 million people. Its main congregational arm in North America is the United Synagogue of Conservative Judaism, and its primary seminary is the Jewish Theological Seminary in New York. Beyond North America, affiliated communities operate under the name Masorti, united globally within Masorti Olami. What draws that many people to a movement famously described by one of its own chancellors as a gimmick to get Jews back to real Judaism? The answer lives in the history, the arguments, and the rulings that shaped Conservative Judaism from a 19th-century European debate into a distinctly American institution.

• 2. Frankel's Middle Way

  ›

  Zecharias Frankel was appointed chief rabbi of the Kingdom of Saxony in 1836, and from that position he began carving out a theological space that neither Reform nor Orthodox would claim. In private correspondence that same year, he wrote that forward progress in Jewish practice should be reached unnoticed, seeming inconsequential to the average spectator. That caution defined everything that followed.

  His first major public confrontation came in 1842, during the second Hamburg Temple dispute, when he opposed a new Reform prayer book for eliminating petitions for a return to the Land of Israel. He also opposed the Orthodox ban on the same book, calling it primitive. Neither side fully trusted him, and that suited him. In December 1843 he launched his magazine Zeitschrift für die Religiösen Interessen des Judenthums, where he set down his core idea: the development of Judaism must proceed on a positive, historical basis, through scientific research, not through reform that would lead to total dissipation.

  The decisive rupture with Reform came on the 16th of July 1845 in Frankfurt am Main. At a rabbinical conference, a slight majority adopted a resolution stating there were no objective imperatives to keep Hebrew as the language of prayer. Frankel vehemently protested that Hebrew was of dire importance and great sentimental value. When the others cited rabbinic literature allowing prayer in the vernacular, he could not contest their halakhic logic, but he saw in the vote a sign of profound differences. On the 17th, he formally withdrew and published a sharp critique of the proceedings.

  The rupture with Orthodoxy came more slowly. In 1854, Frankel became chancellor of the new Jewish Theological Seminary of Breslau. Then in 1859 he published Darke ha-Mishna, praising the Chazal as bold innovators. Rabbi Samson Raphael Hirsch branded him a heretic and demanded a clear statement on whether Frankel believed the Oral and Written Torah were of divine origin. Frankel's response was deliberately ambiguous, and Rapoport, who had initially defended him, joined the critics. Historian Michael A. Meyer noted that the extraordinary status Frankel gave to the ingrained beliefs and practices of the Jewish community was probably the most original element of his thought, turning popular sentiment into a source of religious legitimacy for both change and, mostly, preservation.

• 3. The Seminary Takes Root

  ›

  In 1885, the Pittsburgh Platform declared Reform principles in plain language: only moral laws were binding, and ceremonies were valid only if they elevated life. That explicit statement drove a handful of conservative-minded ministers out of the Reform coalition. Henry Hochheimer, Frederick de Sola Mendes, Aaron Wise, Marcus Jastrow, and Benjamin Szold joined Alexander Kohut and Sabato Morais in seeking a traditional rabbinical seminary.

  In 1886, they founded the Jewish Theological Seminary of America in New York City. Kohut, a Frankel adherent who held the chair of Talmud, became the main educational influence in the early years. The term Conservative Judaism, which Kohut used to describe what the seminary intended to espouse, had no independent meaning at the time. It was defined entirely in relation to Reform.

  The JTS was small and ordaining barely one rabbi per year when Chancellor Morais died in 1897. What changed everything was the arrival of a massive wave of Jewish immigration from Eastern Europe. By 1920, 2.5 million immigrants had arrived, increasing the size of American Jewry tenfold. They came from regions where emancipation and modernization had made little headway, and they were alienated by the assimilated Jewish world they found in America, especially by Reform Judaism.

  Jacob Schiff and other wealthy Reform philanthropists of German descent saw an opportunity. They donated $500,000 to the JTS, with one condition: Solomon Schechter must be appointed chancellor. Schechter arrived in 1902 and immediately reorganized the faculty, dismissing Henry Pereira Mendes and Bernard Drachman for lack of academic merit. Under his leadership the seminary became a serious scholarly center. On the 23rd of February 1913, Schechter founded the United Synagogue of America, initially comprising 22 communities. He refused to describe himself as leading a new denomination: not to create a new party, he said, but to consolidate an old one. When he died in 1915, the boundary between Conservative and Orthodox Judaism in America was still far from settled. JTS graduates served in Orthodox Union congregations, and the two bodies even negotiated a possible merger in 1926, though it came to nothing.

• 4. Becoming a Third Movement

  ›

  World War II changed the arithmetic of American Jewish life. Some 500,000 Jewish GIs were demobilized and left the densely packed immigrant neighborhoods of the East Coast for the suburbs. They were Americanized but retained traditional sentiments, and Reform felt too radical for most of them. The United Synagogue of America offered familiar religious surroundings that were comfortable but not strict.

  The movement expanded from 350 communities by 1945 to 832 by 1971. At its peak, around 350,000 dues-paying member households belonged to Conservative synagogues, and polls showed over 40 per cent of American Jews identifying with the movement. In a 1955 study, sociologist Marshall Sklare called Conservative Judaism the quintessential American Jewish movement, but immediately noted the gap between rabbis and their congregants. Rabbis, he wrote, now recognize that they are not making decisions or writing responsa, but merely taking a poll of their membership.

  The institutional separation from Orthodoxy was solidified by two rulings in the 1950s. In 1950, the Committee on Jewish Law and Standards enacted a temporary ordinance allowing driving on the Sabbath for the sole purpose of attending synagogue services, decreeing that the combustion of fuel did not constitute one of the acts forbidden during the construction of the Tabernacle. In 1954, the Orthodox Rabbinical Council of America reversed its own earlier ruling permitting microphones on the Sabbath, and declared that mixed-gender seating was banned. These two attributes, driving to synagogue and mixed seating, became the visible demarcation line between the two movements.

  In 1962, Rabbi Marshall Meyer founded the Seminario Rabinico Latinoamericano in Buenos Aires, laying the groundwork for Conservative expansion in South America. In 1979, four communities formed the Israel Masorti Movement. Rabbi Louis Jacobs, dismissed in 1964 from the British Orthodox rabbinate on a charge of heresy for espousing a non-literal understanding of the Torah, joined the Conservatives and founded Britain's first Masorti community. The movement had become genuinely international, eventually uniting its global affiliates under the umbrella of Masorti Olami.

• 5. Law in Motion

  ›

  The Committee on Jewish Law and Standards, known as the CJLS, is the movement's central legal body: 25 voting specialists and 11 observers, with any responsum requiring at least six supporting votes to become an official position. What makes it distinctive is that the CJLS can adopt multiple conflicting rulings on a single question, and the local rabbi, carrying the traditional title Mara D'Atra (Lord of the Locality), retains final authority in each community.

  The rulings issued over the decades read as a chronicle of the movement's ongoing argument with itself. In 1950, the board ruled that closing an electrical circuit did not constitute kindling a fire and was therefore permissible on the Sabbath, though it urged congregants to preserve the spirit of the day. In 1952, members of the priestly caste were permitted to marry divorcees, on condition they forfeited their priestly privileges. In 1954, the longstanding problem of agunot, women whose husbands refused to grant a divorce, was largely addressed by inserting a clause into prenuptial contracts requiring men to pay alimony until they conceded. In 1968, this mechanism was replaced by a retroactive expropriation of the bride price, rendering the marriage void.

  The question of women in religious life dominated the 1970s and 1980s. By 1976, the percentage of synagogues allowing women to bless during Torah readings had grown from 7 per cent to 50 per cent. In 1983, a responsum by Rabbi Joel Roth provided the halakhic basis for women's ordination, noting that some earlier decisors acknowledged that women could bless when performing positive time-bound commandments, particularly citing the way women had historically assumed the Counting of the Omer. The resolution to ordain women rabbis was adopted at an open vote in which all JTS faculty regardless of qualification were counted, a procedural choice that prompted the Union for Traditional Judaism to secede in protest.

  In 2006, the CJLS took up the question of openly gay rabbinic candidates and chose a middle course. The committee agreed that human dignity was of supreme ethical importance, but not sufficient to remove an explicit Biblical prohibition. It lifted all restrictions except the one on full anal intercourse, and approved the admission of openly gay candidates to the rabbinate. In 2012, a commitment ceremony for same-sex couples was devised, though it was not classified as kiddushin. In 2016, the rabbis passed a resolution supporting transgender rights.

• 6. A Gap Between Clergy and Pew

  Charles Liebman and Daniel J. Elazar calculated in the mid-1980s that barely 3 to 4 per cent of Conservative congregants actually followed an observant lifestyle quite thoroughly. That figure captures the central tension that Conservative leadership never fully resolved.

  The rabbinate understood itself as bearing a unique and original conception of Judaism. The majority of congregants experienced the movement differently: as a middle option, more traditional than Reform yet less strict than Orthodoxy. As scholar Edward S. Shapiro observed, most were Conservative Jews because their rabbi kept kosher and the Sabbath, not because of their own religious behavior.

  Rabbi Neil Gillman, one of the movement's progressive voices, wrote in 2005 that after repeated concessions, the original halakhic claim had died a death by a thousand qualifications, losing all factual meaning. In a 1999 special edition of the journal Conservative Judaism, rabbis Elliot N. Dorff and Gordon Tucker stated that the great diversity within the movement made the creation of a theological vision shared by all neither possible nor desirable.

  The membership numbers told the same story in a different register. The 2013 Pew Research Center survey found that 18 per cent of Jews in the United States identified with the movement, down from over 40 per cent in the 1970s. Among those under 30 in 2013, the figure was 11 per cent. Steven M. Cohen calculated that as of 2013, some 962,000 U.S. Jewish adults considered themselves Conservative: 570,000 were registered congregants and a further 392,000 identified without synagogue membership. By November 2015, the United Synagogue of Conservative Judaism had 580 member congregations, a sharp decline from 630 just two years earlier. In 2011, the USCJ launched a plan to reinvigorate the movement, and that same year Rela Mintz Geffen estimated that only 100,000 members lived outside the United States and Canada. The demographic imbalance within the movement was equally striking: three people over 55 existed for every single person aged between 35 and 44.

• 7. Global Shape Today

  ›

  Beyond the United States, Conservative Judaism takes the name Masorti, meaning traditional in Hebrew. The Israeli Masorti Movement was founded in 1979 and today incorporates about 70 communities and prayer groups with several thousand members. Hungarian Neolog Judaism, with a few thousand adherents and roughly forty partially active synagogues, is regarded by Conservative Judaism as a fraternal non-Orthodox but halakhic movement, though it is not officially affiliated with Masorti Olami.

  In Latin America, the branch known as Masorti AmLat is the largest outside North America, with 35 communities in Argentina, seven in Brazil, six in Chile, and eleven more spread across other countries. The British Assembly of Masorti Synagogues has thirteen communities and estimates its membership at over 4,000. More than twenty communities operate across Europe, with three in Australia and two in Africa.

  The movement's rabbinic seminaries are spread across three continents. In New York, the JTS remains the original institution, joined by the Ziegler School of Rabbinic Studies at the American Jewish University in Los Angeles, the Seminario Rabinico Latinoamericano in Buenos Aires, and the Schechter Institute of Jewish Studies in Jerusalem. The Conservative Yeshiva in Jerusalem, which does not grant rabbinic ordination, operates along traditional yeshiva lines. The USCJ maintains the Schechter Day School Network, comprising 76 day schools across 17 American states and 2 Canadian provinces. Its Camp Ramah system provides children and adolescents with summers in an observant environment.

  The current chancellor of the JTS is Shuly Rubin Schwartz, in office since 2020 and the first woman elected to that position in the institution's history. The global youth movement is called NOAM, an acronym for No'ar Masorti, with its North American arm known as United Synagogue Youth. That the same institution which once debated whether to hire female faculty now places a woman at its head is perhaps the most concrete illustration of what Conservative Judaism means by a law that is both binding and subject to historical development.
