Translated by Edward T. Oakes, S.J. The book makes clear how much the issues dividing Catholicism from Protestantism had been transformed in the course of four centuries. It shows how a fundamental rethinking of issues could lead, not just to a rapprochement between the two great rivers of Western Christianity, but to an astonishingly new understanding of the Christian message in the modern world. The entire book has been translated from the original German.
