Dialogue between Jews and Christians is of the utmost importance to both communities of faith. This thesis examines the status and role of one particular constituency which has a vested interest in the process and outcome of that dialogue. The people concerned are the Messianic Jewish community, which is to say, Jewish people who, from conviction, have accepted that Jesus of Nazareth is indeed Israel's Messiah. They claim to be firmly established in the full teaching of the New Testament about the person and work of Jesus, and at the same time irrevocably Jewish in their own persons and lives. Whereas there have been a few sociological studies of specific groups of such Messianic Jews, or Hebrew Christians, as some prefer, this thesis has three distinctives: a) It is primarily a theological study. b) It is an examination of the whole movement. c) It is an attempt to let the movement's leaders speak for themselves, and at some length. The thesis of the thesis is that dialogue should be opened up by both the Church and-the Synagogue with the Messianic Jewish movement.
