Well, we were a very select number last night - only four of us (and all but one of those were Bradys). It so happens that all the other church officers are away at present and even some who might have been there were ill or otherwise engaged. I cannot complain as I was away last week on holiday and hope to be at the Banner Conference next week. I pressed on with 2 Timothy, talking about the Christian as an athlete. As there were only four of us we prayed in turn rather than waiting on each other.
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.
