# Reform Judaism
The liberal movement within [[Judaism]] that emerged in the early 19th-century German states and became, in America, the largest Jewish denomination. Its founding premise is that Judaism is a developing religious civilization rather than a fixed legal system - that revelation is progressive, that Jewish law is a human record of the encounter with the divine rather than binding statute, and that ethical monotheism rather than ritual observance is the tradition's core. Everything that follows, including its politics, follows from that premise.
## Founding and origins
Reform is a child of Jewish emancipation. When the legal ghetto walls came down across Central Europe after the French Revolution, Jews faced a question the tradition had never had to answer: what does Judaism look like for citizens rather than for a tolerated corporate minority? Israel Jacobson's 1810 school and synagogue at Seesen and the 1818 Hamburg Temple offered one answer - vernacular sermons, organ music, mixed seating, abbreviated liturgy, and the removal of prayers for return to Zion and restoration of the sacrificial cult.
Abraham Geiger supplied the intellectual architecture, applying historical-critical scholarship to Jewish texts and arguing that a tradition demonstrably shaped by history could be consciously reshaped. The movement's center of gravity moved to the United States with the German Jewish migration; Isaac Mayer Wise built its American institutions - Hebrew Union College (1875), the Union of American Hebrew Congregations (1873), the Central Conference of American Rabbis (1889).
The **Pittsburgh Platform of 1885** is the movement's high-water mark of radicalism: it rejected dietary law and the priestly code as no longer binding, denied that Jews constitute a nation, and rejected the expectation of return to Palestine. The **Columbus Platform of 1937** reversed course on nationhood and made peace with Zionism as the Holocaust approached, and the **1999 Pittsburgh Statement of Principles** went further still, affirming the value of mitzvot and Hebrew and traditional practice - a century-long arc from radical universalism back toward selective traditionalism.
## Core beliefs and practices
Autonomy is the operative principle: individual Jews, informed by tradition, decide their own practice. In institutional terms this has produced a series of firsts - **Sally Priesand ordained as the first American woman rabbi in 1972**; formal acceptance of **patrilineal descent in 1983**, which the other movements rejected and which remains the sharpest denominational fault line in world Jewry; ordination of openly gay and lesbian rabbis from 1990; and endorsement of same-sex marriage in 2000, fifteen years before *[[Obergefell v. Hodges]]*.
## Major divisions
Reform is the American branch of what is called **Progressive** or **Liberal Judaism** elsewhere; the World Union for Progressive Judaism is the international body. In Israel the movement is small and, until recently, denied state recognition for conversions and marriages - a persistent grievance in the relationship between American Jewry and the Israeli rabbinate.
## Demographic footprint
Roughly 37 percent of American Jews identify as Reform, making it the largest denomination in the largest diaspora community. It is also the most likely to include intermarried households and Jews of no synagogue affiliation, and its retention rate is the movement's standing internal worry.
## Right-wing politics tributaries
**Reform Jews are the demographic the American right is not talking about when it talks about Jews.** They vote Democratic by overwhelming margins, are institutionally committed to church-state separation, abortion rights, LGBTQ equality, and immigration, and their rabbinical body has been among the most consistent religious opponents of [[Christian Nationalism]]. The Religious Action Center in Washington has been a fixture of liberal religious lobbying since 1961.
This produces a specific pattern in right-wing discourse. [[Christian Zionism]] proclaims unconditional support for [[Israel]] while regarding American Jewish liberalism as ingratitude or self-hatred; the phrase "the Jews don't even like Israel as much as evangelicals do" is a fixture of that register. The [[Republican Jewish Coalition]] speaks for a small and mostly Orthodox-leaning slice of the community while being treated as its representative voice.
Meanwhile Reform institutions are targets. The 2018 Tree of Life massacre in Pittsburgh - [[Tree of Life Synagogue Shooting]] - was committed by a gunman motivated by the claim that Jews were importing migrants, the [[Great Replacement Theory]] in its purest form. Reform congregations' visible sanctuary and refugee work made them literal targets of that conspiracy. The vault's [[Antisemitism]] page tracks the broader pattern; the practical point is that the tradition most integrated into American liberal civic life is also the most exposed to the conspiracy theory that treats liberal civic life as a Jewish plot.
