It was good to be at the school yesterday night for a production of Midsummer Night's Dream, in which my son was Oberon. He did very well, as they all did on the whole, especially a very funny Bottom. The setting was the eighties for some reason. My son looked like a cross between David Bowie and Michael Jackson. Bottom wore Freddie Mercury gear. I thought the best joke was the girl taking the part of wall in the play wearing a Pink Floyd The Wall T-shirt. They're at it again tonight.
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.
