I recently heard about this ministry and while reading an article, it had a link to a video about Harry Potter. I posted an article or 2 about that topic a couple of years ago. It's a short video, mostly information that shows some of the stuff in Harry Potter is very much authentic when it comes to the spiritually dark topic of witchcraft, and not just mostly harmless fiction, as some would maintain.
More recently, I've been watching the 'Celebrity Apprentice' show on tv on Sunday evenings; except on Easter / Resurrection Sunday when they featured some new attraction based on Harry Potter. I was going to, but didn't, research to see if there were any blog posts about the timing of that show (promoting witchcraft on Easter...)
