Heathen cultures and religions in many parts of the world involve some form of worship directed toward dead heroes or ancestors.

Religious observances such as Hallowmas, which begins on the evening of October 31, or Halloween (All Hallows’ Eve), preserve to one extent or another, depending on the region, widespread ancient customs and superstitions directly associated with the worship of the dead. As does the “secular” observance of Halloween itself.

Does God’s Word have anything to say about customs involving worship of the dead? Should Christians participate in the Halloween custom?
