Let me offer another take on the "vogue for Dietrich Bonhoeffer." It may refer not to the passing relevance of the man, but to our somewhat superficial (and perhaps passing) embrace of his teachings. Many Christians eagerly read and seek to apply his work in the context of their individual relationship with God; far fewer, I'm afraid, take seriously his vision of faith's societal implications. I just watched the fabulous documentary on his life last week, and the film emphasized Bonhoeffer's radical opposition to the institutional church's willing alignment with state power and priorities. It became far too easy for Lutheran leaders (and Catholics, to a lesser degree) to define the church's interest as the state's interest. Speaking truth to power was left to Bonhoeffer, Niemoller, and a few other notables.
To what extent is the American church speaking truth to power? I remember watching clips of President Bush's February 2003 speech to the National Religious Broadcasters convention, an evangelical-dominated organization. He spoke about the coming conflict that was being forced upon the nation due to Saddam Hussein's refusal to get rid of his WMD. He ended with the Phillips Brooks quote, "Do not pray for tasks equal to your strength, pray for strength equal to your tasks." He was repeatedly met with wild applause indistinguishable from a GOP rally. (Here's the video: the relevant passage is at the end.) I am by no means comparing the Iraq war with Nazi Germany's conquests, but I am led to wonder how Bonhoeffer would respond to thousands of Christians seeming to exuberantly celebrate the prospect of war. Is Bonhoeffer currently in fashion among American Christians, especially in their devotional lives? Yes. Have most American Christians taken seriously the lessons of Bonhoeffer's life and work for our relationship with state power? I have my doubts.
