I was raised Catholic and never had any conflict between Halloween and Catholicism. I had a blast as a kid dressing up for Halloween (OK....as an adult, I still have a blast!).
My husband was raised Southern Baptist and his Church would have Halloween Parties when he was a child. the parties included the standard Halloween spook house with adult Church members (including deacons) dressed up as ghosts, goblins witches etc;
Now, however, his Church declares Halloween celebrations as evil......These very same adults and some of his childhood friends (now adults, themselves) condemn Halloween and say that dressing up as a ghost, goblin, witch, etc; is celebrating evil and devil-worship!
Instead of having children going through a make-beleive haunted house, kids are cycled through an area filled with gruesome examples of car accidents, aborted fetuses, etc;.
I really feel sorry for kids today.
