We were a little low in numbers last night as we came to the end of the opening section of Leviticus. We looked at a lot of verses but I think we got through it okay. We'll need to take a break soon, I'm sure. We had a good prayer session but I cut it a little short perhaps. We had started late as I arrived late owing to technical problems.
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.
