I was sat in the congregation once again yesterday. In the morning Mark Richards from Chesham preached on the parables of the treasure and the pearl of great price. It was very thorough and carefully worked out, a blessing to hear. In the evening one of our deacons led communion and then American Robert Jones, currently studying at LTS, preached from Psalm 16, a psalm clearly very der to him and one that he shared well with us. What a good day among God's people and under god's word. Attendances were quite good. As a result of Mark's children's talk my youngest son tells me that if we really can't have a dog, he might settle for a metal detector.
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.
