"0ur world today is in dire need of a shared Christian ethic of service and love for all humanity. This important book provides the catalyst for us to learn, to speak, to ponder, and to find a common voice. It is a new starting point for ecumenical understanding and modeling unity to institutions of learning." —Emmanuel Adamakis, Greek Orthodox Metropolitan of France & President of the Conference of European Churches "First published in German, this English translation has a twofold aim: first, it is an introduction to the social ethical thinking of the three major Christian traditions; second, it demonstrates that the different approaches complement each other – while at the same time providing ample material for clarifying various issues within each of the traditions and among them. In this way the book takes an important step toward enhancing ecumenical cooperation in ethical responsibilities in society, mapping out common ground for practical cooperation." —Kurt Cardinal Koch, President of the Pontifical Council for Promoting Christian Unity
