C.S. Lewis - "I'm going to make the single most catholic fairy tale ever. This thing will be such catholic, woah, watch out, catholic comin' out of your ears with this fairy tale."
The Gays: Smiling, rubbing hands together, menacingly
He failed at Catholic in a sense. He was an atheist who was converted by none other than the devoutly Catholic J.R.R. Tolkien who was then supremely annoyed that Lewis said, "you're right. God exists. The Anglican flavor."
I think Tolkien also wasn’t impressed with the unsubtle ASLAN = JESUS. Lewis gives the vibe of the convert that just has to do THE MOST. When you read like the Abolition of Man, you can tell he thinks of himself as a modern St Augustine.
He wasn't. Tolkien, when asked about the various pseudo-Christ figures in his books (Aragorn, Gandalf, and Frodo specifically), always stated that he hated allegory as a literary device.
