C. S. Lewis held to a lot of false beliefs.
This is interesting. I've never been able to get into the works of C.S. Lewis's, even though many around me speak of them very highly.
I remember when some of the Christian circles I was around were condemning the Harry Potter franchise (and I do understand why), but yet would champion the C.S. Lewis Narnia movies when they came out, even arranging church outings to see them at the theater.
I'm not judging or condemning anyone who might be into either of these series --I fully understood that Harry Potter was about witchcraft, so that was easy to see why many Christians were outspoken against it.
But the part I didn't fully understand was why many of those same Christians would then somehow champion another set of works that contained pretty much all the same things -- witches, mythical creatures, talking animals, and magic -- but somehow this version was called a "beautiful Christian allegory" because Aslan, the talking lion, was a symbol of Christ who sacrificed himself for others.
I have my own thoughts about fantasy and sci-fi, but for my own self, I found it to be a bit of an egregious inconsistency that as long as it had a "Christian" label assigned to it, suddenly many of the same things that Harry Potter was condemned for was now being promoted as a "Christian example."
I wasn't even into either of the series at the time -- I just found myself wondering over what I found to be very mixed messages.
