I've ended up attending two ministers fraternals this week. On Monday it was the very traditional Westminster Fellowship down in Wesminster Baptist. There Philip Eveson preached to us and spoke on very interestingly on Psalms, especially the structure of the book, followe dby discussion. We also prayed. There were about twenty of us adn it was all very helpful. Then on Wednesday I joined the North London Baptist pastors walking across Hampstead Heath. Quite postmodern, we simply walk, stop for a cuppa and then walk a little more before dispersing. There were about ten of us. Again, very enjoyable. I guess there is a place for both sorts of fraternal. I am certainly thankful for both.
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.
