Almost time for bed but don't want to sleep without noting Newport County's stirling effort tonight against the league leaders. I listened to the first half on Radio 5 when they held City to a 0-0 draw. I was then busy and sorry to hear the final scoreline although it was close until near the end I think.
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.
