Please see the following explanation of the origins of the tradition of Halloween, which includes the EPISISCOPALIAN religion amongst others, as those that, through the OBSERVANCE of All Saints Day (1st Nov), and the vigil held on the night of the 31st Oct., first sowed the seeds of the Halloween tradition that survives today.

"Halloween (the name) means the evening before All Hallows or All Saints' Day, which is Nov. 1. All Saints' Day is observed by Roman Catholics, Episcopalians and Lutherans, to honor all the saints in Heaven, whether known or unknown. The day also used to be called Hallowmass from Old English word hallow, meaning sanctify. In the Roman Catholic Church, it is, with all solemnity, considered one of the most important observances of the church year. It is a day on which all Catholics are obliged to attend Mass. It is preceded by a vigil of preparation on the evening of Oct.31. And it is this vigil, All Hallows' Eve or Halloween, that is the most widely known feature of the observance."
