We had our international quiz evening last Saturday and it was an encouraging time. We had a good turn out with about 30 present, including good number of outsiders. The quiz went okay (though the questions could have been easier). Robin Asgher spoke well. There was a lovely spread of food and just about enough of it. Lots' of people worked very hard. We had been finding that midweek meal and message was not working so well perhaps this new approach will be the way forward.
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.
