# Conservative Judaism
The centrist movement in American [[Judaism]], founded on the proposition that Jewish law is binding *and* historically developing - that halakha genuinely obligates, but that the community of Israel across time has always been its interpreter. Known as **Masorti** ("traditional") outside North America. A note on the name, because it trips people constantly: "Conservative" here means conservative relative to [[Reform Judaism]], not politically conservative. Conservative Jews vote Democratic at rates close to Reform Jews.
## Founding and origins
Zecharias Frankel walked out of the 1845 Frankfurt rabbinical conference over the proposal to abandon Hebrew as the language of prayer, and his **Positive-Historical Judaism** became the template: positive toward the tradition's binding claim, historical in its scholarly method. Frankel's Breslau seminary trained a generation that would neither follow Reform in discarding law nor follow Orthodoxy in denying that law had a history.
The movement became decisively American. The Jewish Theological Seminary was founded in New York in 1886 by traditionalists alarmed at Reform's Pittsburgh Platform - and at the notorious 1883 "trefa banquet" that served shellfish at a Hebrew Union College ordination. **Solomon Schechter**, brought from Cambridge in 1902, built JTS into a serious institution and coined the movement's guiding idea of **Catholic Israel** (*klal Yisrael*): that the authority to interpret law rests with the practice of the whole faithful community, not with rabbinic decree alone.
The United Synagogue of America followed in 1913. Conservative Judaism became the denomination of Jewish suburbanization - by midcentury roughly a third of American Jews - because it offered a way to be recognizably traditional and fully American at once.
## Core beliefs and practices
Halakha binds, but it develops. The mechanism is the **Committee on Jewish Law and Standards**, which issues responsa and, unusually, may validate multiple contradictory positions simultaneously, leaving congregational rabbis to choose. The landmark decisions map the movement's arc:
- **1950** - permitting driving to synagogue on Shabbat, a ruling widely credited with enabling suburban Conservative Judaism and widely criticized within the movement ever since as the moment observance began to erode.
- **1983** - JTS votes to ordain women; the first women rabbis are ordained in 1985.
- **2006** - the committee adopts contradictory responsa on homosexuality, permitting ordination of gay and lesbian rabbis and same-sex commitment ceremonies while also validating the traditional prohibition.
- **2012** - approval of same-sex marriage rituals.
Conservative Judaism rejected patrilineal descent when Reform adopted it in 1983, and that rejection is the practical boundary between the two movements in matters of personal status.
## Major divisions
The **Union for Traditional Judaism** broke away in 1984 over women's ordination. On the other flank, the boundary with Reform has grown porous as both movements' younger members drift toward nondenominational and independent minyanim. The movement's structural problem is legible in its own terms: a denomination whose theory demands observance and whose membership largely does not observe.
## Demographic footprint
Conservative Judaism has fallen from roughly a third of American Jews at midcentury to about 11 percent in Pew's 2020 study - the steepest denominational decline in American Jewish life. Its losses have gone in both directions, toward Reform and unaffiliation on one side and toward Orthodoxy on the other.
## Right-wing politics tributaries
Conservative Judaism's political significance is largely as part of the American Jewish liberal majority that [[Christian Zionism]] and the [[Republican Jewish Coalition]] talk past. Its rabbinic body has been consistently critical of [[Christian Nationalism]], and its institutions have been active in refugee resettlement and civil rights work.
Two specific tributaries are worth tracking. First, the movement is the clearest test case for a claim the American right often makes about religion generally - that theological liberalization causes institutional collapse. Conservative Judaism's decline is genuinely dramatic, and the "moderation kills denominations" argument gets made about it constantly, including by Orthodox commentators. The counter-evidence is that [[Reform Judaism]], which liberalized far more, grew. The variable is probably not doctrine.
Second, the movement's internal fight over Israel policy - between institutional Zionism and a younger cohort sympathetic to groups like [[Jewish Voice for Peace]] - is one of the places where the American right's insistence that criticism of Israeli policy is antisemitism collides with actual Jewish communal argument.
