Bonhoeffer, AR-15s, and Adventist Ethics—Part I (8 Feb 2013)
Every ethic must undoubtedly have a context. This is first of all a Christian ethic. But Christian ethics, like Christian faith, must be considered through the lens of a tradition. Since the Seventh-day Adventist tradition has been so informative for me, and likely for many readers, I want to draw from the relevant aspects of the Adventist tradition, though I will not draw from Adventist tradition exclusively. It is in this spirit that I want to juxtapose the ethics of the German Lutheran theologian Dietrich Bonheoffer with the historical Adventist tradition of conscientious objection.
Bonhoeffer, AR-15s, and Adventist Ethics—Part II (17 Feb 2013)
