The movement for religious reform in modern Judaism represents one of the most significant phenomena in Jewish history during the last two hundred years. It introduced new theological conceptions and innovations in liturgy and religious practice that affected millions of Jews, first in central and Western Europe and later in the United States.Today Reform Judaism is one of the three major branches of Jewish faith. Bringing to life the ideas, issues, and personalities that have helped to shape modern Jewry, Response to Modernity offers a comprehensive and balanced history of the Reform Movement, tracing its changing configuration and self-understanding from the beginnings of modernization in late 18th century Jewish thought and practice through Reform's American renewal in the 1970s.
