Frances Ridley Havergal (1836 – 1879) was a Worcestershire born poet and hymn writer born in an Anglican rectory. Take My Life and Let it Be is one of her best known hymns. She also wrote hymn melodies, religious tracts and works for children. More here.
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.
