Hans Urs Von Balthasar here addresses the issue of theological pluralism in the twentieth century. God's revelation, he argues, is like a great symphony, which contains within it both the unity of God's plan and the polyphony of "instruments" and "sounds" of the creation. It is only in the person of Jesus Christ that we can see the organization of the symphony. Part I addresses the various aspects of theological pluralism that are encountered as we circle around the heart of the Christian revelation, Jesus Christ. Part II consists of examples that illustrate the way the multiplicity flows from the unity and is grounded and can at any time be reintegrated therein.
