Our next two sessions looked at union with Christ historically. Bob Letham of WEST presented a paper on Calvin and John Fesko of Westminster Theological Seminary in California on the communion controversy, where one William Sherlock replied to Owen on communion with God. The chairmen were Kevin Bidwell and Mike Plant. We had a good discussion session touching on our understanding of the Lord's Supper, the Song of Solomon and various other matters. We appear to be agreed on things in general but the opportunity to sharpen up our understandings is proving useful. Sorry not to give more background but each paper is long and fairly detailed. The papers will be published in due time I understand.
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.
