Rabbi Delphine Horvilleur is all about building bridges – but she isn’t afraid to burn them when she spots something deeply disturbing on the other side.

She is a Reform rabbi in a mainly Orthodox community; a progressive in a largely conservative and increasingly insular Jewish community; a supporter of interfaith dialogue as the Jewish community takes hard-line positions in response to growing anti-Semitism; and a critic of Israeli policies as the community increasingly lines up with the government in Jerusalem.
