Halloween originated in Celtic cultures the day before Samhain, the beginning of the Celtic winter. It focused on death blending in the supernatural. The Catholic Church incorporated non-Christian traditions into its holidays to bring people to the church. It scheduled All Saints (Nov 1 ) and All Souls (Nov. 2) after Halloween. All Soul’s focused on those who had died without the supernatural. All Saints celebrated all who believed and were baptized The word saint originally meant “holy”. Later it became a feast day commemorating all martyrs.
