We just recently investigated the origins of Halloween. Although we let our kids participate last year and years prior ages 7, 5 and 3 1/2. It all started with Paganism. My husband and I also had the debate, but I refused to participate. If they were going to go out, he was going to have to do it all, even buy the costumes. I wanted to do what is pleasing to the Lord. Participating in the holiday, knowing its origins would be displeasing to the Lord. I have to agree with your husband, that it is not a Christian holiday. In fact, just the oposite. This is our first year not participating, so we didn't have a "plan" for a substitute. My kids asked about it, but didn't miss it. As it was put to me, it's almost more for the parents' pleasure to see their darlings all dressed up, but if they don't...they won't know what they're missing. Harvest gatherings seem to be the substitute I've heard about. God bless.
