Rowling is a devout Anglican, and allowed Christianity to have a strong affect on how she portrayed the magical powers, as well as how she portrayed the main characters and the struggles of good vs evil.
What, you mean like the miracles of Saints?
The only supernatural things that happen on Earth come from a conflict between good and evil. So… you have the Holy Spirit, Mary, the saints, and angels, vs. the devil and his works, pomps, and minions.
Other than that, I’m going to have to say in the most sincere way possible: start living in the real world. Outside of the forces of Heaven and Hell there’s nothing unnatural or “fantastical” that occurs on Earth.
These things are born of our God-given imaginations, and always have been. There’s nothing wrong with enjoying the fantastical. Or are you saying that partaking of our imaginations, through which we attempt to discern or understand a being who would not only create us, but then sacrifice Himself for us, is inherently evil?
God has to have an imagination, of some form; otherwise, where the heck did we come from? Not to mention all the gloriously wonderful and varied creates that have existed on our planet throughout history.
No, I would say that the imagination is just like everything else. Neither good nor evil by its own accord, but colored one way or another by how we use it. In terms of Potter, it is used to create a magical world where there is a true, visible battle between good and evil. It’s a refreshing representation of our own battle with Satan and with sin, which is far less visible. There is the constant temptation to give in and use the abilities for personal gain (the felix felicitatous (sp?) potion, for example), and any time the characters give in to rage and anger, they are made to regret it in a visceral and directly apparent ways (when Harry Uses Secusempra in rage). The stories are full or very good life lessons about what it means to stand on the truth, regardless of the mockery you receive for it (basically the entire fifth book), and the entire story is prefaced by the truth that love is sacrifice (The sacrifice of Lily and James)
No, if you actually read them, you would see that, far from Pagan and occult, these books are truly inspiring, and manifest of a beautiful understanding of the human person, and the true and invaluable nature of the soul.
