I notice there is now a drinks machine at London Theological Seminary. I have sampled the product and found it satisfactory. The new Principal is clearly making an impact. But will it improve the work of the students? Do take part in the poll.
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.
