The folks over at Worldviews, the World Magazine blog, make the observation that political satire is tres chic these days, citing such luminaries as Stephen Colbert and Ann Coulter. They then ask whether anyone has examples of contemporary Christian literature that "lampoons" the current state of the world.
Well, I suppose it depends on your definition of "contemporary", but I would think that many of the novels of G. K. Chesterton (circa. 1874-1936) would have to count, as well as much of his non-fiction, particularly books like Heretics and Orthodoxy, and many of his newspaper columns. And certainly Walker Percy's novels, particularly Love in the Ruins, and The Thanatos Syndrome, which are wildly clever send-ups of the pathologies of modern life and thought, would have to be considered.
And while we're talking about Christian satire, a web search turns up the very interesting post at "John Mark Ministries" on the subject of Christian satire.
