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.
It was good to be with the family at the wedding of my father-in-law to Barbabra.
They were married by Barbara's pastor Paul Levy.
There waa a lovely cake reception at Gunnersbury Baptust Church and a reception at the nearby Pilot to follow. Good day.
