The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. 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.
The EMW Aber Conference 2018 is now under way. I am not in Aber at present but I did listen to Dave Gobbett online preaching helpfully on "Faith that works" from James 2:14-26. The main meetings are all being streamed and can I think be accessed here on Youtube.
