Since the groundbreaking publication of Postmissionary Messianic Judaism (2005), Mark Kinzer has challenged theologians and religious leaders to consider the essential ecumenical vocation of Jewish disciples of Jesus. Proposing a bilateral ecclesiology in solidarity with Israel, he argued that the overcoming of Christian supersessionism required a robust affirmation of the distinctive calling of Jews within the community of Jesus the Messiah. In this way, Kinzer''s work put the issue of Jewish followers of Jesus on the theological agenda for those seeking a reparative reconfiguration of the relationship between the church and the Jewish people. In recent years, Kinzer has attended to the theological implications of this perspective and has widened his focus to include not only the Messianic Jewish movement but also Jews within Catholic, Orthodox, and Protestant churches. The present collection of essays reflects this wider concern. According to Kinzer, the theological stones of contention are Christology conceived of as Messianology, ecclesiology understood as Israelology, and eschatology imagined as Zionology. Moreover, it is the presence of Jewish disciples of Jesus that concretizes these theological abstractions in the form of Jewish flesh and blood, summoning Jews and Christians to rethink their relationship to one another in ways that express their essential mutual dependence.
