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 culturehere. 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.
Tyndale New Testament - from Matthew 8
And lo there arose a great storm in the sea, in somuch that the ship was hid with waves, and he was asleep. And his Disciples came unto him, and awoke him, saying: master, save us, we perish.
