The Bible does not mention Halloween. However, both the ancient origins of Halloween and its modern customs show it to be a celebration based on false beliefs about the dead and invisible spirits, or demons.—See “Halloween history and customs.”

The Bible warns: “There must never be anyone among you who . . . consults ghosts or spirits, or calls up the dead.” (Deuteronomy 18:10-​12, The Jerusalem Bible) While some view Halloween as harmless fun, the Bible indicates that the practices associated with it are not. At 1 Corinthians 10:20, 21, the Bible says: “I do not want you to be participants with demons. You cannot drink the cup of the Lord and the cup of demons too.”​—New International Version.
