This thinker's argument that naturalism is self-defeating led to a 1948 debate at the Oxford Socratic Club with G.E.M. Anscombe about his book, Miracles. He claimed that Christianity is the story of a rightful king arriving incognito in enemy-occupied territory to fight the devil in a lecture titled (*) "What Christians Believe". He borrowed from Vincentius of Lerins the concept of reducing Christianity to only those principles that were believed "always, everywhere, by everybody", and he adapted a term from Richard Baxter to describe that form of Christianity. The argument that Jesus was either a lunatic, a fiend, or the Son of God is this man's "trilemma", which he presented in a series of BBC radio broadcasts delivered during World War II. For 10 points, name this English Christian apologist of The Problem of Pain and Mere Christianity.
