The original Celtic pagan holiday was to ward off the spirits attempting to return home- Catholics appropriated the holiday as “all hallows Eve” preceding “all saints day”
Similar to Easter and Christmas- Catholic holidays are celebrated on previously pagan holidays.
The name Halloween comes from “All hallows Eve” (Catholic practice)
The modern theme of Halloween has reverted to its pagan roots, except for the name- and without spirituality or due respect for the dead- Which modern pagans (and some Christians) argue was the intention of Catholic leadership.
