Halloween often becomes a topic of debate, with critics arguing it’s a pagan festival that was later Christianized. Some say it stems from Samhain, an ancient Celtic harvest festival, and accuse the Catholic Church of "baptizing" pagan rituals to make them palatable to early converts. Others claim Halloween is a celebration of evil and demonic forces, making it unsuitable for Christians.
Both views are misleading. Halloween, properly understood, is deeply rooted in Catholic tradition, with its origins tied to All Saints' Day (All Hallows’ Day) and All Souls' Day. These feasts honor the saints in heaven and pray for the souls in purgatory, reflecting a profoundly Christian worldview. Let’s explore the historical and theological roots of these celebrations, debunk the myths surrounding Halloween and Samhain, and offer guidance for Catholics seeking to reclaim the true meaning of Halloween.
The word "Halloween" comes from "All Hallows’ Eve," the vigil preceding All Saints' Day. This feast commemorates all the saints in heaven, both canonized and unknown, and is followed by All Souls' Day, when Catholics pray for the souls in purgatory. Together, these celebrations emphasize the Christian understanding of the communion of saints, the reality of purgatory, and the hope of eternal life.
Many believe Halloween originated from Samhain, a supposed ancient Celtic pagan festival. Critics claim this day marked a liminal time when the dead walked among the living, and bonfires were lit to ward off spirits. However, this narrative is rooted in modern folklore rather than historical evidence.
Scholar Ronald Hutton, in The Stations of the Sun: A History of the Ritual Year in Britain, demonstrates that Samhain was primarily an agricultural festival marking the end of the harvest season, with little evidence of religious or supernatural connotations. He notes, “There is no firm evidence that it was regarded as a day when the living and the dead mingled, nor that it involved elaborate religious rituals.”
Similarly, Robert Davis of the University of Glasgow asserts that Samhain had no direct connection to Halloween. “The claim that Samhain was a Celtic New Year or a religious festival marking a transition between the worlds of the living and the dead is largely a 19th-century invention,” he writes. Furthermore, the idea that Samhain influenced Christian celebrations is undermined by historical timelines. All Saints’ Day was celebrated as early as the 4th century in the Eastern Church, long before Christianity reached Ireland.
The placement of All Saints' Day on November 1 was not an attempt to "baptize" Samhain. The feast originated in the Christian East and was celebrated on May 13 for centuries. Pope Gregory III moved the date to November 1 in the 8th century, but this change followed a Germanic Christian custom—not an Irish pagan one. In fact, Irish Christians originally celebrated All Saints on April 20, showing no connection to Samhain.
As Hutton concludes, “The medieval records furnish no evidence that November 1 was a major pan-Celtic festival or that it involved religious ceremonies of any kind.” The narrative linking Halloween to Samhain is, therefore, historically inaccurate and unsupported by evidence.
The feast of All Saints honors the "great cloud of witnesses" (Hebrews 12:1) who now share in God’s glory. All Souls’ Day reflects the Catholic practice of praying for the dead, rooted in Scripture (e.g., 2 Maccabees 12:46) and the Church’s teaching on purgatory. Together, these feasts remind us of the interconnectedness of the Church triumphant (saints in heaven), the Church suffering (souls in purgatory), and the Church militant (the faithful on earth).
The feast of All Saints was instituted to honor the countless martyrs of the early Church, many of whom were unnamed. Pope Boniface IV dedicated the Pantheon in Rome to the Blessed Virgin Mary and all martyrs on May 13, 609. The date was later moved to November 1 by Pope Gregory III to align with the lurgical calendar in parts of Northern Europe, where this date had already gained local popularity. All Souls’ Day was added in 998 by Abbot Odilo of Cluny, who encouraged prayers for the dead, reflecting the Christian belief in the efficacy of intercessory prayer.
These feasts are profoundly hopeful. All Saints’ Day reminds us of our ultimate calling to holiness, while All Souls’ Day invites us to reflect on our mortality and pray for those undergoing purification. Far from being morbid, this focus on death encourages us to live virtuously, mindful of our eternal destiny.
