All Hallows' Eve and its Catholic Roots
On October 31, we celebrate the eve of All Saints. Pope Sixtus IV in 1484 established November 1, the feast of All Saints, as a holy day of obligation and gave it both a vigil (known today as "All Hallows' Eve" or "Hallowe'en") and an eight-day period or octave to celebrate the feast. By 1955, the octave of All Saints was removed. All Hallows' Eve Halloween or All Hallows' Eve is not a liturgical feast on the Catholic calendar, but the celebration has deep ties to the Liturgical Year. These three consecutive days — Halloween, All Saints Day and All Souls Day — illustrate the Communion of Saints. The Church Militant (those on earth, striving to get to heaven) pray for the Church Suffering (those souls in Purgatory) especially on All Souls Day and the month of November. We also rejoice and honor the Church Triumphant (the saints, canonized and uncanonized) in heaven. We also ask the Saints to intercede for us, and for the souls in Purgatory.
