I decided to go with resurrection themes again this Lord's Day and so we looked at the rest of John 20 and part of John 21. Numbers were a little low in the morning, which was followed by lunch together (mountains of food it seemed). We were 18 in the evening which is good for us. We had visitors in at both services.local people who we hope will come again. We have sung 16 resurrection hymns over the last two Sundays. All excellent hymns. We did not know one or two tunes sadly, which was a pity. There are others we haven't tried for a lack of knowledge of them.
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.
