I was glad to get down to see Richard II at the Globe last week, especially as I'd ended up missing the other history offering this year - King John. I had particularly enjoyed the Ben Whishaw BBC version on TV a few years ago and so had high hopes of what, on the face of it, is a difficult and uninspiring play with few great quotes (This sceptre Isle is the only one I spotted). The lead this time was taken by Charles Edwards (who I recognised from Downton Abbey) and he made a fine stab at it. The others were all okay too but I felt it didn't really grip us quite somehow. Ah well. The music was provided by a set of shiny trombones. That was done very well.
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.
