(JNS) A coalition of 51 Jewish and pro-Israel organizations has adopted the International Holocaust Remembrance Alliance’s (IHRA) working definition of anti-Semitism.

The organizations are members of the Conference of Presidents of Major American Jewish Organizations, which announced the adoption on the eve of International Holocaust Remembrance Day.

The two other members of the umbrella organization, Americans for Peace Now and the Workers Circle, did not adopt the definition.

The IHRA definition says: “Anti-Semitism is a certain perception of Jews, which may be expressed as hatred toward Jews. Rhetorical and physical manifestations of anti-Semitism are directed toward Jewish or non-Jewish individuals and/or their property, toward Jewish community institutions and religious facilities.”

The adoption follows the approval (without objection) of a Conference of Presidents resolution calling for member organizations to adopt the IHRA definition in November. The definition received bipartisan support in Congress and is consistent with and builds upon definitions endorsed by the last three presidential administrations.

A group of left-wing Jewish and Israeli groups issued a joint statement this month in opposition to adopting the definition, claiming that doing so would silence criticism of Israel.

The collection of groups—known as the Progressive Israel Network—include Ameinu, Americans for Peace Now, Habonim Dror North America, Hashomer Hatzair World Movement, Jewish Labor Committee, J Street, New Israel Fund, Partners for Progressive Israel, Reconstructing Judaism and T’ruah: The Rabbinic Call for Human Rights.

The Conference of Presidents penned a letter to then-U.S. President-elect Joe Biden stating that the definition “is now the most comprehensive and authoritative definition of anti-Semitism” and therefore “all federal departments and agencies” should consider adopting it. Agencies charged with carrying out Title VI are already required to do so.
