Pretty typical week off this week - reading, walking, Private Eye, TV, etc. I read most of Mission at Nuremberg which I started reading a while back then put down but took up again recently having read the HHhH book. The whole Nazi era is endlessly fascinating and there were things here I did not know or had forgotten. I read a much shorter book on similar lines by F T Grossmith many years ago. This is a larger book that gives you the whole of the life of Major Gerecke the Protestant chaplain as well as plenty of other material on the history of chaplaincy, Lutheranism, etc, etc. The writer is lucid and fair minded but liberal in his theology. It is clear that several Nazis made credible professions of faith and some refused to believe but it is hard to be sure what to make of it all. In many ways Gerecke's pastoral work was similar to that of any other pastor.
The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.
