It was a privilege to be among the 14 or 15 people present for the latest lunch time lecture at the Evangelical Library here in London. Dr Robert Strivens, Principal of the London Theological Seminary, spoke of the Synod of Dort. He very helpfully and clearly gave us the background to the Synod that took place in the Dutch town of Dordrecht (Dort for short) 1618 and 1619 and then something about the (Calvinistic) canons it produced. Dr Strivens was at pains to acknowledge the political as well as theological currents in existence at the time. A recording was made and can be obtained from the Library. A good time of questions and answers followed. We also learned how recent the TULIP term is (more to follow on that I hope). (For the canons of Dort see here). The best book of the subject will cost you a small fortune sadly. See here.
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.
