On a serious note...
The whole reason I mention Purim is because I'm the product of Lutheran Sunday schools, Bible school, vacation Bible school, catechism, and everyday regular Lutheran school kindergarten through 8th grade. In other words, I've been taught a lot about what I'm supposed to see as evil. And I'm thankful for the Biblical background the Lutheran education gave me.
But it also taught me to question every rigid set of "this is evil" rules I was given, because it was a constant inflow.
And I'm certainly not trying to say that we shouldn't stay away from evil.
But I saw the churches that condemned anyone for reading or watching Harry Potter (magic, spells, talking animals, witches, enchantments) arrange for entire church outings to go see things like The Lion, The WITCH, and The Wardrobe (Narnia -- magic, spells, talking animals, witches, enchantments) because it's by a Christian author and Aslan (magic enchanted lion) is "an allegory of Christ."
Now I'm not saying people shouldn't stay away from Harry Potter -- I believe God will convict people individually of such things -- but I also have a very hard time with people saying, "Witches and magic -- secular author, bad; witches and magic -- Christian author, good! Support! Read! Go See! We've reserved a bus so there's no excuse for all you church members not to go and see it!"
Yeah.
Anyone who tells me, "This is EVIL! (from the world) but this other thing (from a Christian) THAT USES THE SAME THINGS is GOOD!" -- is going to have give me a lot more to work with than than just that.
Because what I've found is that there are a lot of Christians out there who aren't interested in making you like God. They're most interested in making you like them. And if you don't talk like them, act like them, think like them... You're not a Christian.
As a single person, I was recruited many times by people pushing their own ministry agendas rather than what God had in mind, then told I was being rebellious if I didn't take the bait. So I proceed only with the utmost caution, and I don't take "warnings" at face value.
But, that's just me.
