Schnackenburg's reflections on the Lord's Prayer and the Sermon on the Mount emerged, as he notes in his preface, in the context of the peace discussion of the 1970s and 1980s in Germany. That context played an important role in shaping the reflections, but, though much has changed in the intervening decades, the reflections in this new English translation remain relevant and timely. Reading the Sermon on the Mount and the Lord's Prayer together proves to be a fruitful technique by which to illuminate both, particularly to the extent that the intimate and confident tone of the prayer Jesus taught his disciples informs the extraordinary ethic he elaborated in the programmatic sermon reported by Matthew and Luke. Schnackenburg's pithy recapitulation of the history of interpretation of the sermon is an excellent introduction to Christian ethics. That, along with the insights into the Lord's Prayer and Schnackenburg's own contribution to the continuing history of interpretation, makes this an important book for anyone interested in Christian ethics "after Auschwitz."
