Well, I may have a bit of a different perspective about Halloween than some. I do understand and acknowlege the pagan roots, and for that reason I take my little cousin to our church's event. The word Halloween isn't even mentionedthere. It's called Trunk or Treat or something like that. It's more like a carnival. Oops. A Carnival...that word kind of has pagan roots too. Maybe we should shut down Six Flags.
I'm being silly, but what I mean is that even Oct. 31 falls under the category of: "This is the day that the Lord has made, let us rejoice and be glad in it." I don't think we should so easily let ourselves be robbed of something that - although had pagan origins - is now a fun time for kids to play and get candy. We have to make culture adjustments, teach our kids how things change, and tell them the story and what we do, and DON'T celebrate. Believers of Jesus do not commemorate or give any authority to the historical aspects of halloween.
