Ethics (Bonhoeffer book)

Ethics (Ethik) is an unfinished book by Dietrich Bonhoeffer that was edited and published after his death by Eberhard Bethge in 1949. Bonhoeffer worked on the book in the early 1940s and intended it to be his magnum opus. At the time of writing, he was a double agent; he was working for Abwehr, Nazi Germany's military intelligence organization but was simultaneously involved in the 20 July plot to assassinate Adolf Hitler. The central theme of Ethics is Christlikeness. The arguments in the book are informed by Lutheran Christology and are influenced by Bonhoeffer's participation in the German resistance to Nazism. Ethics is commonly compared to Bonhoeffer's earlier book The Cost of Discipleship, with scholars debating the extent to which Bonhoeffer's views on Christian ethics changed between his writing of the two books. In The Cambridge Companion to Dietrich Bonhoeffer, John W. de Gruchy argues that Ethics evinces more nuance than Bonhoeffer's earlier writings. In 2012, David P. Gushee, director of Mercer University's Center for Theology and Public Life, named Ethics one of the five best books about patriotism.
