Next week, thousands of people will crowd into Congregation B’nai Jeshurun at 88th Street in Manhattan for Kol Nidre services. It’s a safe bet that the rabbis at one of the country’s most politically progressive synagogues will sermonize about social justice, the stagnant Israeli-Palestinian peace process, or the upcoming presidential election: After all, this is a congregation that hung an anti-torture banner in the sanctuary during the Bush Administration. B’nai Jeshurun is justly proud of its liberal pedigree—and a look at the synagogue’s website indicates that it has always been on the right side of history. The synagogue was formed in 1824-25 when a group of Ashkenazi members of Shearith Israel, which had been New York’s only synagogue for nearly 100 years, split off to create a fully egalitarian community by drastically lowering required contributions and instituting an executive committee whose membership rotated every three months. Rabbi Israel Goldstein carried that mantle in the first half of the 20th century, and later the synagogue hosted Eleanor Roosevelt, Martin Luther King, and Abraham Joshua Heschel.
