Eventually, this celebration became the Christian holiday of All Hallow's Day. The Christians spent this day honoring the saints of the Church. The night before, on All Hallow's Eve (or Halloween) people dressed in masks and costumes meant to represent the saints. It was their duty to lead the spirits of the dead out of town before the next day's celebrations.

When the celebration became All Hallow's Day, why did the Christians dress up as saints and wear masks?
