I'm reading Kael "The Lion, the Witch, and the Wardrobe", which I haven't read in probably a quarter century, and it is such a different experience now. I mean, I was prepared for the whole Aslan = Jesus thing, but it was still quite a surprise to hear Lewis's Trilemma in a children's book. And yes, it's the same Lewis.
Allegorical borrowing from one of the foundational texts of Western civilization is one thing, but allegorical borrowing from your own apologetic writing, and putting it in the mouth of a character whose name means "church"? I know you can do better than this, C.S. Please see me after class.
