Two of my grandsons were visiting on Wednesday. They like to go to the chess club at the library and I love to take them so off we went. During their visit they mentioned that they were putting up the Halloween village that night. Decorating for the ghosts and ghouls rivals even Christmas these days. It's not a trend I like. On the other hand, if you're going to do it, christianize it. Make at least some of those decorations reflect the faith. How about putting a few monuments in the cemetery: a crucifix, a monument to our lady, the staue of a saint, etc. I have a little collection of miniatures some of which could easily be used in an All Hallow's Eve village.
Traditionally All Hollow's Eve was a Christian feast preceding All Saints Day. Here's a bit about its origin:
