A new book by Rabbi Ruth Langer, a professor of theology and associate director of the Center for Christian-Jewish Learning at Boston College, has been hailed as “masterful” by Jewish Ideas Daily. Rabbi Langer is an expert in Jewish tradition and Jewish-Christian relations. According to the publisher (Oxford University Press), in Cursing the Christians?: A History of the Birkat HaMinim, Rabbi Langer traces the transformation of the birkat haminim from a medieval Jewish curse of Christians to its modern transformation within the Jewish world into a general petition that God remove evil from the world.
