Who are the Messianic Jews? What do they believe and practice? What is the Jewish community’s reaction to the development of Messianic Judaism? In this pioneering study, Dan Cohn-Sherbok traces the development of the Messianic movement from ancient times to its transformation after World War II. Focusing on the nature of the movement today, the volume continues with a detailed examination of Messianic practices, and the place of Messianic Judaism within the contemporary Jewish community.
