I spent this morning in Rayleigh, Essex, speaking on Proverbs to a gathering of people from UEC churches at one of their Faith Matters days. Around 30 people gathered and hopefully I managed to stir them to want to read Proverbs and forearmed them against some of the pitfalls. The UEC is a group of 15 churches (formerly the Peculiar People), nearly all in Essex. See here for more. What a great way to spend a morning!
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.
