Dietrich Bonhoeffer (1906–1945), a German theologian, pastor, and ecumenist, was a professor in Berlin, an uncompromising teacher in the Confessing Church, and a consistent opponent of National Socialism. Executed by Hitler at the end of World War II, his influence continues today as one of the most important theologians of the twentieth century. Bonhoeffer penned countless letters, portions of fiction, and several works on theology and ethics that have shaped modern religious thought. Life Together and The Cost of Discipleship are two examples of this modern martyr’s enduring legacy.
