It was great to be at the wedding of my sister Gail on Thursday. She was marrying Paul Summerfield. It was great to see the wedding take place and to be at the reception and to meet up with family and old friends. God is good.
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.
