Not in any sect. Don't call sun worship, witchcraft, etc Christian.

I've read the complete Narnia Chronicles numerous times. I've even discused The Lion The Witch and The Wardrobe with Theology majors and professors at my religious college. All agree this is a book laced with Christian values etc.
I pose one question to you, where in this book do they worship the sun?
Granted an evil witch put a spell over the land to make it permanently winter and never christmas. All the creatures of the land wanted spring to return; but no one prayed to a sun god. It was a belief that when Aslan comes back to Narnia and 4 human children sit upon the throne at Cair Parival spring will return to the land and the evil witch will be defeated.
I highly reccomend that you at least read this book, or the whole series for that matter, before spewing your comments/judgements on it.
