Here is the only argument I received from my Narnia post.

Argument

I've read the chronicles of Narnia 2-3 times through and probably read the Lion the Witch and the Wardrobe more times than that.

The question here isn't really whether or not the "Magic" in that other world called Narnia is good or bad, or even an allegory of a good thing. But, the question is, should a Christian associate with magic? (Galatians 5:19-20)

In the Lion the Witch and the Wardrobe, there was little magic done by the good guys. However, in following books from Narnia, you do see some of that. The Voyage of the Dawn Treader had the dufflepuds turned to different beings by a sort of "fallen star" or Wizard. Not to mention the magic rings which were, maybe good, maybe bad.

Rebuttal

As I explained before, the Magic in The Lion the Witch and the Wardrobe is not really magic. A Christian can not be associated with magic if there is no real magic, hence my debunking the magic theory to see if it really was magic. The same goes for the magic and magician in The Voyage of the Dawn Treader. They were used to test Lucy.

Galatians 5:19-20 “The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions”

The Greek translation of witchcraft is what our English word pharmacy is derived from. The Greek word could have the positive meaning of dispensing drugs. The real and more common meaning is the use of drugs in sorcery and witchcraft to poison people.

Argument

And as for mythological creatures, I'd say your rebuttal is slightly lacking. Why? Because people are real life things. You can't get away from humans. Mythological creatures are fake and if not, they were/are demonic. Back in olden times, people would see dwarves, fauns and satyrs. Nowadays we see aliens.

Rebuttal

In Lewis’s work, he portrayed a few mythological creatures as good, and he portrayed a few as bad. His good creatures were good and his bad creatures were bad. It does not matter if they appear in any other work, since his book is fiction.

Argument

I don't pretend like I didn't like chronicles of Narnia, or LOTR. I did enjoy them, but I don't actually read them anymore. I don't think that the things that aren't true ought to be thought on (Philippians 4:8)

Rebuttal

A lot of life application can be gained by reading fiction and non-fiction. According to your statement we should not read any fiction. As for the Philippians verse, we need to be led of the Holy Spirit. But I do want to say, if we follow that verse to a “T” then we will be excluded from reading the Bible. After all, the Bible does have a lot of violence in it. 

Narnia defines good verses evil. Here is a quote from Prince Caspian: “So that is your plan, Nikabrik! Black sorcery and calling up of an accursed spirit.” The story goes on, and the wicked hag is killed. Good triumphs over evil.

One of the writers of NJAO made a good point.

“Isn't it odd that some believers waste their time taking moral stands against something because of petty concerns?  They completely detract from its potential as a godly influence.”
