I think we're missing Ramon's point. Don't be deceived friends. Every holiday celebrates something. Halloween is a pagan holiday promoting Satanism, idolatry, witchcraft, sorcery, necromancy, and the occult. None of these things should exist in the life of a Christian! They are spiritually dangerous, and should be avoided at all costs. What does the Bible have to say about the idea of Halloween, and the activities often associated with this pagan festival? I refer you to Deuteronomy 18:9-13: Deuteronomy 18:9-13 - "When thou art come into the land which the Lord thy God giveth thee, thou shalt not learn to do after the abominations (idolatry) of those nations (pagans). There shall NOT be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer (those who talk with the spirits of the dead). For ALL that do these things are an abomination unto the LORD: and because of these abominations the LORD thy God doth drive them out from before thee. Thou shalt be upright with the LORD thy God."
Final note: Did you know that October 31st is considered by Satanists and other occult following adults to be one of their most important days of the year? It’s true! And Halloween has the highest crime rate of any day of the year. Why do you think that is? Because it's a celebration of spiritual darkness.
So please don't give glory to the Devil by actively participating in this pagan festival. Give Glory to God Alone through Jesus Christ and the Father of Light!
