We've had two family celebrations this week. Yesterday we had a meal to celebrate the fiftieth wedding anniversary of my parents-in-law, Geoff and Iola Thomas. About 24 family and friends gathered at a nearby hotel. We ate a nice meal then there were some speeches and Joel Beeke kindly closed in prayer. Then today it was a more dressed down chip dinner for the extended family, including relatives over from America (my wife's youngest cousin, Gwennan, and her family). It was Gwennan and Keith's son Joshua's eleventh birthday. We must have been over 40 this time.
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.
