It was possible once again this week to sit in as an auditor for a series of lectures from Garry Williams on Covenant Theology. There was a bumper turn out of some 14 men, most of whom are doing the MTh course. Garry's approach was to give us his notes with a series of questions which we worked through as well as tackling a number of set texts (by Boston, Petto, etc) presented by the students working for credits. It was great to work through the material on the various covenants trying to come to some conclusions on the various issues. If they repeat the course, it is one well worth attending.
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.
