I think I missed this when it first came around. In the video above, Doug Wilson argues that C. S. Lewis was a Calvinist, and he makes the case from various selections from Lewis’ writings. I’m no Lewis scholar, but this sounds really novel and unlikely to me. I wonder if any Lewis-philes would offer an alternate perspective on this.
UPDATE: John Piper just weighed-in saying that Lewis was not a Calvinist but now is.
