Hal David the lyricist most associated with Burt Bacharach the writer and Dionne Warwick the singer died last Saturday aged 91. This is not the only use of religious imagery in songs by David, who was Jewish.
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.
