Eastern Germany is considered the most secular region in the world. Some even claim that in this region, it has been forgotten that one has forgotten God. Here, at the focal point of a secular society, the conference documented in this volume took place. The contributions explore how the relationship between mission and spirituality must be redefined in light of globalization and pluralization: What spiritual foundation shapes the mission? How does personal spirituality motivate an open confession in a society that seemingly wants to hear nothing of Christianity? The authors seek answers from an interdisciplinary perspective: within the German local church, in the responsibility of individuals for others, and in a global church context. They compellingly illuminate the connection between spirituality, mission, and mercy in order to find new, courageous paths.
