Vatican II''s Declaration on the Relation of the Church to Non-Christian Religions (Nostra Aetate) transformed the Catholic view of the Jewish people and the Jewish religious tradition. Asserting that the Church discovers her link to the "stock of Abraham" when "searching her own mystery," Nostra Aetate intimated that the mystery of Israel is inseparable from the mystery of the Church. As interlocking mysteries, each community requires the other in order to understand itself. In Searching Her Own Mystery, noted Messianic Jewish theologian Mark S. Kinzer argues that the Church has yet to explore adequately the implications of Nostra Aetate for Christian self-understanding. The new Catholic teaching concerning Israel should produce fresh perspectives on the entire range of Christian theology, including Christology, ecclesiology, and the theology of the sacraments. To this end, Kinzer proposes an Israel-ecclesiology rooted in Israel-Christology in which a restored ecclesia ex circumcisione--the "church from the circumcision"--assumes a crucial role as a sacramental sign of the Church''s bond with the Jewish people and genealogical-Israel''s irrevocable election.
