The Girls of Slender Means by Scots writer Muriel Spark has sat on my shelf for some time unread. It's a well known title by a well known author and so putting down my heavy theological tome last week I dipped in. It's not a long book and I had it read quite quickly. The title is quite a clever play on the word slender I guess although it is a straightforward enough story in its own way and worth reading. It was written in 1963 and takes place chiefly in 1945 in a ladies boarding house in London. Anthiny Burgess out it in his top 99 books and it was commended when pubklished by Auden, Waugh and Updike.
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.
