Apparently it the source of their power is Almighty God, He's the one that grants them the genetic gift necessary to do magic even if they've learned nothing about it, even if they don't know that wizards exist.
People can do good, they aren't necessarily the source, but they are not powerless observers of the world.
Magic in HP isn't pacts with the devils like in the Bible. The magic they have in HP is innately neutral, it's how it's used that's good or bad.
What I'm calling evil is driving people away from the Faith. That's evil, not good.
Absolutely not, which is exactly why the Harry Potter books do not adhere to the biblical/Christian worldview. Which is why parents should be careful to make sure their children understand that.
Any powers God gives are to be used for HIS PURPOSES ONLY, and any powers we use that aren't for the purposes of advancing His kingdom interests and bringing glory to his sovereignty come from the Devil. The children in Harry Potter bring glory to themselves through their use of magic.
POWER IS NOT NEUTRAL. One must understand the source of power to understand its purpose.
The Bible doesn't speak of "pacts with the devil" being the sources of evil power in the Bible. Nor are all of the practicers of witchcraft in the Bible trying to harm others. It is very sad that people like you believe that it would be so obvious. The Devil is not obvious in his methods. This is exactly why Cardinal Ratzinger said children could be "subtly influenced". It's never so apparent as some nasty looking witch with a big nose trying to boil little children. If that were all the occult was about, then it would be easily avoided.
No, it's about trying to take for yourself that which rightfully belongs to God only (the power to get others to do things, and to get what YOU want, not what God wants).
Another problem with the Harry Potter stories is the source of their power. The source of the power is the children themselves, not any Higher Power such as Jehovah God.
People who don't have these powers are derisively called "muggles" and are made fun of and ridiculed. I see that expression being tossed around Free Republic too.
But that is exactly the opposite of how people who get their power from God would behave. It's a priviledge, a great honor, it should humble you. The power doesn't make you superior in any way, BECAUSE IT IS GOD'S POWER. And it is never to be used for selfish purposes.
The people who were honored with powers in the Bible had to go to great lengths to make sure it was understood that God was the source, and not they themselves. When Moses made the mistake of saying that he made the rock give water, he was severely humbled by God for that.
It is a dangerous and untrue notion that we can have any kind of good power without God. No, people cannot be the source of good. It is by imitating the source of good that people may appear to be good. But we must not allow anything to draw attention away from the source, especially with children.
The Harry Potter books are all about how these children have these powers from within themselves, and they use it for "good" because they want to. They could just as easily use it for evil, as others who have the "genetic" powers do.
