Can the Christian celebrate Halloween?

The answer is simple: Yes and No. Let’s look at the negative first. The Christian is not to be involved with or support the occult, witchcraft, demonism, or any other thing that uplifts the occult. To do so is to contradict God’s word, dabble in demonic spirits, and invite judgment from God. If a Halloween celebration is centered on demons, devils, spirits, etc., I would say don't have anything to do with it. On the other hand, it isn't wrong to dress up in a costume and go door-to-door saying 'Trick or Treat." Provided that the costume isn't demonic, I can't see anything wrong with this. It's just fun for the kids. Take a look at the Christmas tree. It was originally an ancient fertility symbol. Yet, it has become a representation of Christmas and the place where gifts are placed. Are the Christians, then, paying homage to an ancient pagan fertility god? No. Not at all. They do not consider it pagan at all and are simply joining in on a cultural event and giving no honor to anything unbiblical.

My thoughts: why celebrate this "holiday" at all. I mean this seems to be a night that lasts for about 2 or 3 hours then it is over. I can find better things to do with my time than collect candy and other junk.
