We had lunch together in church yesterday, as we do from time to time. We are always well fed. In the morning I completed the first chapter of 2 Peter looking at verses 12-21 (about remembering truths and abouit Scripture). We will get back to the other chapters some time in the future. In the evening I completed a brief series on Habakkuk, which has been okay. We had a few visitors but quite a few missing. We'll start on something more Christmassy next week.
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.
