A critical confrontation of Dietrich Bonhoeffer’s theology with current, alien problems. In an unconventional way, the authors of this volume confront Dietrich Bonhoeffer’s theology with current issues and issues, such as intercultural understanding, ecology, globalization, the return of religion and the function of theological ethics in secular society. Since these problems were mostly foreign to Bonhoeffer, there is a critical reading of his work and an unprejudiced discussion of the relevance of his thinking to the present. This creates a new, attractively alienating perspective on Bonhoeffer’s work. The concept of mystery, which is important to Bonhoeffer’s thinking, covers the individual considerations.
