As I was in Central London on Tuesday I did something I have been meaning to do for some time. I went to have a look around Handels' house in Brook Street. It is done very nicely. We began with a nice audio visual and then looked around the relatively small house. As with most of these houses, it is down to your imagination really. I have been to hear Messiah but am not a big Handel fan. I enjoyed it though and was interested to learn about his librettist Charles Jennens, who I want to find out more about. You have to pay to get in but I'm glad I finally got round to it after so many years (it opened 2001 I think). Read more here. London is full of brilliant things.
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.
