I've been reading Edith Wharton's novella Ethan Frome. It is a well told and powerful tale that reveals a story of passion and sadness in 19th century rural New England. Part of the story teller's art is to book end the piece with references to the then present and these give the main story a strength that it would probably otherwise not have. Only around 99 pages it is quite a work and well deserves the praise it has been given as Wharton's best selling work. Early reviewers though it too cruel but given a little distance one can cope with it easier by hoping nothing so dire would ever happen to me or those I love. It is quite a moral tale in its iown way. It is crying out to be filmed. I notice that was done in 1993 with Liam Neeson (director John Madden), how successfully I don't know not having seen it.
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.
