Dietrich Bonhoeffer was a German Lutheran pastor, theologian, anti-Nazi dissident, and key founding member of the Confessing Church. His writings on Christianity’s role in the secular world have become widely influential, and his book The Cost of Discipleship became a modern classic.
Apart from his theological writings, Bonhoeffer was known for his staunch resistance to the Nazi dictatorship, including vocal opposition to Hitler’s euthanasia program and genocidal persecution of the Jews. He was arrested in April 1943 by the Gestapo and imprisoned for one and a half years and then transferred to a Nazi concentration camp. After being associated with the plot to assassinate Adolf Hitler, he was quickly tried, along with other accused plotters and executed as the Nazi regime was collapsing.
