Q. Is Halloween a pagan or a Christian holiday?
A. In terms of its origins, Halloween is both pagan and Christian. In terms of its practice, that depends on who’s celebrating.
Before the coming of the Christian faith to Celtic lands (the British Isles and Brittany), a pagan feast that seems to have been associated with the harvest and New Year’s Eve on the Celtic calendar took place on the night of October 31. In the Druid religion (practiced by the Celts), the night of October 31 was considered a time when the lord of death, named Samhain, allowed the souls of the dead to roam. (Some scholars, we should note, have disputed some specifics of these historical claims.)
