Same-sex marriage in Judaism has been a subject of debate within Jewish denominations. The traditional view among Jews is to regard same-sex relationships as categorically forbidden by the Torah. This remains the current view of Orthodox Judaism, but not of Reconstructionist Judaism, Reform Judaism and Conservative Judaism, which started changing its position to same-sex unions in 2006.
As the issue of same-sex marriage has broached the forefront of social and political consciousness in the United States over the past few years, it has also become more prevalent in the Jewish community as well. Certain branches of Judaism that had until recently been less open to gay rights have made organizational advances on the issues. The Conservative Movement was the last of Judaism’s liberal streams to adopt a more progressive streamlined approach to dealing with issues related to homosexuality. Even within the insular Orthodox community, there is a small, but growing population of individuals and leaders who are actively engaged in the struggle for same-sex marriage as a secular institution in America. Rabbi Steven Greenberg is an openly gay Orthodox rabbi who is leading the charge among open-minded Orthodox and traditionally-observant Jews around the world. Leading Orthodox rabbis have denounced reparative therapy and have embraced a much more toned down approach to homosexuality in Judaism. Each year dozens of observant Jewish students "come out of the closet" and many have increasingly remained involved in organized Jewish life. Organizations have been established to assist Jews struggling with the perceived dichotomy between living a traditional Jewish life and being homosexual. Eshel was established by Rabbi Greenberg as a platform to advocate for greater acceptance of LGBT Jews in Orthodox life. Jewish Queer Youth (JQY) also exists as a platform to connect with and advocate for LGBT rights within Jewish communities around the country.
Orthodox Judaism maintains the traditional Jewish bans on both sexual acts and marriage amongst members of the same sex. The Orthodox Union in the United States supported a federal Constitutional amendment banning same-sex marriages. In Australia, the Organisation of Rabbis Australasia (ORA) have made submissions and written public letters against legalising same-sex marriage.
