Many of you will be aware that tomorrow is both Mother's Day and the day the clocks go forward. No doubt many mother's are on the street with others complaining about this juxtaposition. Mothers are basically losing an hour of the one day in the year when they are not doing everything.
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.
