THE BIBLE’S ANSWER
The Bible does not mention Halloween, a holiday that many observe on October 31 each year. However, the ancient origins and traditions of Halloween conflict with Bible teachings.

Notice the following verses that show how God views the beliefs associated with Halloween:

1: “There must never be anyone among you who . . . consults ghosts or spirits, or calls up the dead.”—Deuteronomy 18:10-12, The Jerusalem Bible.

Meaning: God does not approve of efforts to contact the dead or even of giving the appearance of trying to have contact with those who have died.

2: “The dead know nothing at all.”—Ecclesiastes 9:5.

Meaning: Because the dead are unconscious, they cannot contact the living.

3: “[Do not] be participants with demons. You cannot drink the cup of the Lord and the cup of demons too.”—1 Corinthians 10:20, 21, New International Version.

Meaning: Those who want God’s favor must avoid any connection with demons.

4: “Stand firm against the crafty acts of the Devil; because we have a struggle . . . against the wicked spirit forces.”—Ephesians 6:11, 12.

Meaning: Christians should oppose wicked spirit forces, not pretend to celebrate with them.
