All growing up the rule was we could dress up in costume, anything we wanted as long as it was clean and was not demonic. We didn't dress up as witches, goblins, ghosts, demons. Nothing of that sort. It was the one day of the year I could dress up as any character I admired and have fun getting candy. It was no more than that. We had to stay in a group and usually we went for hours. I have so many fun memories of it growing up.
Here is my solid belief on the matter and I found the perfect way to explain it from this link HERE but I'll copy a certain portion of it for my blog for an easy read.
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.
In the Bible in 1 Cor. 10:23-33, Paul speaks about meat sacrificed to idols. This meat was often sold in the meat market and the question arose, "Should a Christian each such meat?"
Paul said in verse 25, "Eat anything that is sold in the meat market, without asking questions for conscience' sake." This is most interesting. He says it is okay to eat the meat bought in the market place even though that meat may have been sacrificed to idols.
Then in verses 28-29 he says, "But if anyone should say to you, 'This is meat sacrificed to idols,' do not eat it, for the sake of the one who informed you, and for conscience' sake; 29 I mean not your own conscience, but the other man's; for why is my freedom judged by another's conscience?" (NASB). Paul is saying that if you find out the meat was sacrificed to idols, don't eat it -- not because of you, but because of the other person. In other words, eating that meat won't affect you. But, it may affect the attitude of another who does not understand the freedom the Christian has in Christ.
Is it any different with Halloween (or Christmas)? No. Even though Halloween has pagan origins, because of your freedom in Christ, you and/or your kids can dress up in costumes and go door-to-door and just have fun. However, if you are not comfortable with doing this, then you should not.
Tomorrow, yes, I'll be dressing up my kids. I'll be letting the kids play out their favorite character and get candy. No, we won't be participating in sacrifices or praying to demons. After trick or treating we'll be attending the Halloween play again to support it and pray with people. We're really looking forward to a fun night. I really think this is a personal conviction. If God spoke to my heart on he matter, of course I will obey Him. Just as we still put presents around our Christmas tree. We are not worshipping the fertility God. We are just having fun exchanging gifts and celebrating Jesus' birth. Of course we know that was not His actual birth date but it's pretty darn awesome that we set that one day out of the year to celebrate.
Does your family stay home during Halloween or do you dress your kids up?
