Stumbled across this shot from the sixties of Edlogan Square shops, Croesyceiliog. The hairdressers (Moira's and a barbers) and Forbuoys newsagents with the post office is round the corner out of sight. Next was the wool shop, the greengrocers, the butchers, the chemist and Cecil's the grocers (later a mini supermarket).
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.
