A flagship liberal Orthodox synagogue in New York will stop congratulating same-sex couples on their weddings following a complaint by the Orthodox Union.

The Hebrew Institute of Riverdale in the Bronx will no longer announce the weddings of its LGBT members in its newsletters by a policy dictated by the Orthodox Union, the most extensive association of Orthodox synagogues in the United States. The procedure was set out this month in response to complaints from other member synagogues, which take a harder line on opposing same-sex marriage.

Orthodox Jewish law, or halacha, prohibits same-sex marriage, and Orthodox rabbis are not permitted to officiate at same-sex weddings. The Conservative, Reform and Reconstructionist movements allow same-sex marriage.

“It is the Orthodox Union’s unequivocal position that supports for, or celebration of, halachically proscribed conduct is fundamentally inappropriate,” the Orthodox Union statement reads, according to the Five Towns Jewish Times. “Accordingly, the institutional endorsement or encouragement (implicit or explicit) of any conduct that is contrary to halacha is an activity that no Orthodox synagogue should allow.”

The statement said the Orthodox Union is reviewing its congregational standards before taking further action.

The Hebrew Institute of Riverdale, which has long served as a leader in pushing the bounds of traditional Jewish law to include women and LGBT Jews, has been friendlier to same-sex couples. It counts same-sex couples among its members and last year hosted a panel on LGBT Jews in Orthodoxy called “Building a Jewish Future Outside the Closet.”

Its founding rabbi, Avi Weiss, was one of the signatories of a landmark 2010 statement of principles by Orthodox leaders affirming the need to “treat human beings with same-sex attractions and orientations with dignity and respect.”

The synagogue’s clergy does not officiate at same-sex weddings, but the synagogue began including same-sex marriages in its announcements earlier this year. Following the Orthodox Union’s statement, however, the Hebrew Institute’s rabbi, Steven Exler, confirmed to JTA that the announcements would stop.

Mordechai Levovitz, executive director of Jewish Queer Youth, which focuses on LGBT Orthodox teens, said the OU policy would only inflict further damage on that group. He said that 70 percent of the kids who come to his group’s weekly Drop-In Center in Midtown Manhattan report being suicidal.

Levovitz added that he does not blame the Hebrew Institute for its decision following the Orthodox Union statement.

“We have very, very real issues when it comes to LGBT youth in the Orthodox community,” Levovitz said. “HIR is a wonderful shul and it treats its LGBT people wonderfully. It’s the Orthodox Union that’s making a big deal out of this. It’s the Orthodox Union that’s deciding to focus on congratulatory wording and not children and teens who are physically and mentally at risk.”
