These are said to be genuine Spoonerisms spoken by Rev William Archibald Spooner himself
1. You hissed my mystery lecture - you missed my history lecture
2. Cattle ships and bruisers - battle ships and cruisers
3. Nosey little cook - cosy little nook
4. A blushing crow - a crushing blow
5. Our queer old Dean - our dear old Queen
6. We'll have the hags flung out - we'll have the flags hung out
7. You've tasted two worms - you've wasted two terms
8. Our shoving leopard - our loving shepherd
9. A half-warmed fish - a half-formed wish
10. Is the bean dizzy? - is the Dean busy?
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.
