In Deuteronomy chapter 18, as the law of God is presented to a new generation of Israelites prior to their entrance into Canaan, various instructions are given on how they were to conduct themselves once they came in to that promised land. In verses 9 to 15 they are told that 'when thou art come into the land which the LORD thy God giveth thee, thou shalt not learn to do after the abominations of those nations'. Various pagan practices such as divination, witchcraft and necromancy as practiced by the Canaanites are then prohibited. These sinful practices were forbidden to the children of Israel and are described as being an abomination to God, showing them to be loathsome and offensive to his holy name. Indeed it was for the practice of these things that the Lord would drive the Canaanites out of the land (verse 12).
Among these sins here listed there are many practices and which are linked with and familiar to the celebration of Halloween. The satanic practices of sorcery and witchcraft, of human sacrifice and communicating with the dead, condemned by God as being among the vilest of sins, are found at the very root and origin of Halloween. Behind every Halloween custom, when it is traced back far enough, the hand of Satan can be found. Halloween customs such as trick or treat, jack-o-lanterns and bobbing for apples, things which on the surface are fun and harmless, all have their beginnings in ancient pagan druid practices, rituals which can themselves be traced back to Babylonish idolatry and the very things which we find condemned in Deuteronomy 18.
