Mission in crisis - this diagnosis makes immediate sense in view of the rapid decline of European Christian churches. However, there is a great deal of controversy as to what exactly this crisis consists of, what its actual causes are and what dynamics the crisis discourse itself exhibits. The contributions in this volume were held on an international conference that took place from November 25-27, 2022 at the University of Zurich. They pursue these questions from a mission-theological perspective and seek to open up new perspectives for the future of the church in both secular and plural societies. With contributions from: Heike Breitenstein, John G. Flett, Ralph Kunz, Sabrina Muller, Stefan Paas, Henk de Roest, Stefan Schweyer, Patrick Todjeras, Graham Tomlin, Benno van den Toren, and Henning Wrogemann.
