Jer 10:2 Learn not the way of the heathen,… KJV
This article is the best source I have found so far for information about a Christian and Halloween. It actually isn’t as brief as it says.
How much ground should the Christian give the devil? Is there any room for compromise? No, there is none. The Christian should have a holy hatred of the devil and everything he represents. “Give no place to the devil, (Eph. 4:2).” Halloween represents all that the devil loves and propagates against the holiness of God’s character. When Christians participate in occult festivals, they are ascribing glory of the lord Samhain, the devil, the god of this world. They may ease their conscience by saying they are worshipping God at their Fall Festival, the true Lord of the harvest, but when has God ever inaugurated this kind of worship? I have no qualms about having a costume party on June17th, or February 12th, insignificant days (provided the costumes are not degrading or evil). Costume parties are not the issue, nor are they sinful in and of themselves. It is the festival of Samhain which is the issue; it is Halloween. Will Christian parents plan a costume party in July instead of October 31st? No they will not. Why? Because they desire to make their children happy and fit in with the neighbors. Christian parents should be teaching their children to hate worldliness, not thriving after it. “You adulterous generation, do you not know that friendship with the world is enmity towards God? Anyone who is a friend of the world is at enmity with God” (James 4:4-5).
Thank you for the previous comments I am still working on this.
