There was an opportunity to preach in Trafalgar Square again today. Things have changed a lot since we began doing this. We are now down to three hours and don't get use of the plinth. They'd kept the protesting doctors to a spot outside the square at least, however. We had the prime spot. We probably need more powerful speakers. We are competing often with people outside the national gallery. I preached first and Roland Brown, Peter Bell and others followed. It was cold but dry and lots of tracts and Bibles were given out.
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.
