I just don't see where the sin lies. You see it as a promotion of using magic as good vs evil. I see the 'magic' in the movie on a technical level: post production animation. Even real Wiccan's have come out and said the stuff in Harry Potter is just fluff.
Does it portray magic? Yes. Is magic a dominion of Satan? Yes. Is the magic in Harry Potter 'real'? no. Calling the 'magic' in Harry Potter real (to me) is like saying the character, Harry Potter, is real. It's fake "magic", being portrayed by fake characters, by actors who don't believe in magic.
I didnt say, as you say above "a promotion of using magic as good vs. evil"...I said that the movie TEACHES that VICTORY can be achieved through SIN. And further it makes Christians like YOU, teach new christians that watching such drivel is perfectly ok...even if it does promote a false Biblical message...a message that says flee from sin...it doesnt say sit around watch it, be entertained by it, marginalize and justify it...least not in my bible...mine says HAVE NOTHING TO DO WITH IT.
I may have mistaken you for a mature christian in the Lord...that would be my bad, Gods word is not even slightly vague on this...if your a christian, you should really want nothing at all to do with such garbage...it teaches a falsestory of good conquering evil through embracing A SINFUL APPROACH (the magic arts). What good is there in the story that uses and promotes sin to accomplish victory? The answer is obvious...None!
God says "Be Holy, for I AM HOLY"...is the viewer obeying that Command if they Know that "magic arts" are sin? Of course not! Does it mean they cant ever watch such material...no...how can I say that, you should be asking?
Simple, if you are a parent, you have a responsibility to raise your children up in the way they should go, God forms each person in the womb, they are given over to human parents for a time, children are expected to be returned to the Lord,as believing christians, fully aware of the ABSOLUTE HOLINESS of God. Previewing this material as a mature christian parent would be a wise Godly step to 1. Find out what the World wants to teach your children, 2. Showing the child the falseness of what the World "packs" into its entertainment compared to what Jesus says is wise and righteous. Thiswould be acceptable use.
But for the everyday true believing christian, THERE SHOULD BE NO INTEREST IN SUCH ENTERTAINMENT, once it is known to them what the anti-christian message is contained in the storyline. No more than an interest to watch inappropriate contentography...as they are of equal value to the Lord. Be Holy, as I AM Holy...says the Lord. Wisdom to the believer....foolishness to the perishing...
