In the 21st century we are being forced to observe how violently people can react to crises of religious and cultural identity. But the question should not be whether people with different cultural and religious backgrounds want to live together; we should rather ask how coexistence can succeed in such a way that the world may evolve in the direction of a just peace - and also preserve the integrity of creation for future generations. This volume of the 'Berlin Edition for Ecumenism, Mission and Dialogue' offers an English-language collection of important essays on the subjects 'Mission and Dialogue', 'Claim to Truth and Tolerance' and the relationship between religion and state in a pluralistic society.
