I've hardly seen any of it but I am pleased to hear that the British and Irish Lions (as we call them in these days of PC) have won the test series in Australia with a 41-16 demolition of the Aussies in Sydney today with four tries. Lots of things have made this a very sweet victory (16 years since, an emphatic victory, etc). All honour to Warren Gatland. More here.
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.
