How Political Is Political for a Believer...?

The following comments contained in a posting on American Christianity and politics by "pastordan" has some decent remarks on the subject of Christianity and its interaction with politics. ...

pastordan reports that Cary McMullen replied pastordan's comments:

One of my professors at Duke, Stanley Hauerwas, contended that the church IS a political organization in the sense that if the church is properly exhibiting the gospel in the world, there will be political repercussions. For example -- the Confessing Church in 1930s Germany. The Barmen Declaration could be the manifesto for this view that the church, by being the church, is a political organization. To take a smaller example, suppose a local church -- maybe even a Baptist church -- has a prison ministry, and they learn that the local sheriff has policies that restrict prisoners' religious activities. How then should the church behave? I leave that question open.

That's a fair statement as far as it goes. I wonder though how much the churches in Germany should've done before Hitler came to power? Of course, the German people people may have been involved in their own totentanz with the Nazis in such a way that Hitler's rise was inevitable.

Is it then and only then that a sacrifice such as Bonhoeffer's martyrdom of his pacifist principles in order to assassinate Hitler was made possible?
