One of the joys of Christmas is getting new books. I had six new ones this year. There was a University Challenge Quiz Book and A Little Book of London by David Long from two sons and from another and his wife the whopping new John Frame Systematic Theology. I'm very much looking forward to getting into the last of these. Then the sisters-in-law and their husbands weighed in with a list book (a hardback edition of Russell Ash's Top Ten of Britain) and a book for using with kids (66 Books One Story by Paul Reynolds). The piece de resistance came from my wife, a beautiful edition of Umberto Eco's The Book of legendary Lands. Printed on good weighty glossed paper and oozing with colourful illustrations the book examines a number of lost lands and allied themes. With his great erudition and vast knowledge the book is a joy. I have started it and have enjoyed what he has to say on the lost ten tribes and the seven wonders of the world. Each chapter is complete with sources though the tone is never heavy.
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.
