No, the error is yours. The Bible is clear that what people think is magic is actually demonic spirits carrying out the persons’ commands because they have some knowledge of how to interact to get the spirits to do what they want (for awhile). That is why He wants people to have nothing to do with this kind of stuff.
You are falling into the trap because you believe Rowling’s concept of magic being a force the person uses without anything else’s help. That is not what God tells us is behind occultic powers.
You ALMOST got my point, but not quite.
When you say “The Bible is clear that what people think is magic is actually demonic spirits carrying out the persons’ commands because they have some knowledge of how to interact to get the spirits to do what they want”, you SUPPORT my point that the people doing “magic” in the Bible were addressing supernatural beings, rather than taking advantage of “natural” laws as technologists do.
When you say “you believe Rowling’s concept of magic being a force the person uses without anything else’s help. That is not what God tells us is behind occultic powers.” you miss two subtleties.
First, I don’t “believe” IN Rowling’s concept of magic, and neither does she in real life. But I do “believe” THAT, in her FICTIONAL universe, the thing CALLED magic is indeed a force the person uses without anything else’s help, and that belief of mine about the meaning of the concepts in her books is due simply to my being a competent reader of fiction.
Second, when you say “That is not what God tells us is behind occultic powers.” you fall right into the error I had just warned about — YES, that is not what God tells us is behind “occultic powers”, but “occultic powers” IS NOT THE ONLY THING WHICH THE WORD “magic” CAN REFER TO!
The Potter books do NOT have the wizards using “occultic powers”, they have the wizards using something naturalistic which they call “magic”. You may believe that, in OUR universe, the feats they accomplish can only be done by “occultic powers”, but they live in a fictional universe in which that is not the case. In other words, you may believe that the two linguistic terms “magic” and “occultic powers” coincide in our world, but you may not validly trade on this equivalence by substituting one term for the other in a discussion of a FICTIONAL world.
So God told you not to read Harry Potter?
