We got to see the film Dunkirk last week. I don't need to say anything about it except that it is worth seeing. It attempts to give us the experience , which is an obvious thing to do, which menas little explanation and lots of action. Some of the story choices seem strange and people have had a field day with all the inaccuracies of various sorts. I was interested to learn that the man on whom the Mark Rylance character was based had been second officer on the Titanic. The air, land, seainterchange is doen very well. I picked up no hints to the marvellous providenc of God that some speak of and thought the film was generally anti-war, partly by dint of its accuracy. I remember visiting Dunkirk one day on a school trip to Ostende when I was 12. I was surprised when one of my sons (the history graduate I note) told me that the first revelation for him on seeing the film was that Dunkirk is in France not Scotland!
Bonhoeffer uses a similar phrase 'worldly Christianity'. 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.
