Year after year I cringe when it comes to the popular man made holidays which good people celebrate without question, including Halloween.
The folks at Cutting Edge have covered this topic pretty well:
God lists Satanic practices that He absolutely forbids- Every one of them is uniquely associated with Halloween!
1. Enchantment -- Act of influencing by charms and incantation using the practice of magical arts. Such practices draw directly upon the power of Satan. God forbids it in many places, chief among which is Deuteronomy 18:10-12.2. Witchcraft -- Dealing with demonic spirits, using their prescribed methods, commonly called rituals and the "magick arts". The Bible forbids it, as in Galatians 5:19-20. Go to a video store sometime and walk down the "Horror" aisle, where you will see the popularity of Witchcraft in America today.3. Sorcery -- Use of power gained from the prescribed rituals demanded by the demonic host. Once the witch or wizard performs the particular ritual correctly, the demonic host is required to provide the power to accomplish that action desired by the witch.4. Divination -- Fortune telling and seeing into the future. God wants us to trust in Him and His power, and not worry about tomorrow. Satan, on the other hand, loves to get people consumed by the idea that they can know what lies ahead of them. Forbidden in the Bible, Jeremiah 29:8-9 and Deuteronomy 18:10-12.5. Wizardry -- The art or practices of a wizard, sorcery. A wizard or witch is one skilled in the magick arts, a sorcerer. God forbids such practices in Deuteronomy 18:10-12 and Leviticus 19:31.6. Necromancy -- Communication with the dead. Specifically, conjuring up the spirits of the dead for purposes of magically revealing the future or influencing the course of events. Forbidden in Deuteronomy 18:10-12 and Isaiah 8:19.7. Charm -- The practice of putting a spell on someone in order to change or control their mind and/or behavior. Wizards love to get their enemies "one-on-one" because they can "charm" them through the use of ritual done before the meeting, and by the demonic host residing within him. Adolf Hitler followed this practice closely as he dealt with the leaders of Europe, Britain, and Russia. British Prime Minister Chamberlain was totally charmed by Hitler as he sought to appease the German dictator in Munich in 1938; Chamberlain was so totally "charmed" by Hitler, he enthusiastically proclaimed after returning from Munich that he had achieved "peace in our time".When dealing with a powerful member of the Illuminati, do not attempt to meet with him, nor place any confidence in the testimony of people who have met with him. A "charm" ritual is easily performed and results in the leader exuding confidence, character, and sincerity they most assuredly do not possess. God forbids this activity in Deuteronomy 18:10-12.8. Stargazing or Astrology -- Divination of the supposed influence of the stars and other heavenly bodies upon human lives and the affairs of nations. Occultists literally order their lives according to Astrology and numerics. God forbids this activity in Deuteronomy 18:10-12 and Jeremiah 10:2. Also called "Observing the Times".9. Soothsaying -- foretelling events and prophesying through a spirit other than the Holy Spirit. Forbidden in Micah 5:12 and implied strongly in Deuteronomy 18:10-12.10. Prognostication -- To foretell from signs and symptoms, also prophesying without the Holy Spirit. Forbidden in Isaiah 47:12-13.11. Magic -- Tapping into the power of the demonic realm through the use of prescribed ritual so that the action carried out is accomplished through demonic power. Forbidden in Deuteronomy 18:10-12, 2 Chronicles 33:6, 1 Samuel 15:23.
All these activities are uniquely associated with the activities and traditions of Halloween! Christians have no business participating in Halloween. To do so is to act against a great number of Scriptures in which God uses the strongest possible language to forbid it. In fact, in most instances, God decreed that people practicing these activities be put to death!
Yet, we see many churches having Halloween parties in which many of these pagan practices are followed! The Apostle Paul gave us strong warning that should stop us dead in our tracks. Listen:
"Let no one delude and deceive you with empty excuses and groundless arguments for these sins, for through these things the wrath of God comes upon the sons of rebellion and disobedience." Ephesians 5:6]
