Introduction
Halloween, often perceived as a secular or even pagan holiday, has deep roots in Christian tradition. While modern celebrations emphasize costumes, trick-or-treating, and ghostly imagery, the origins of Halloween are closely tied to the establishment of All Saints' Day and All Souls' Day by the Christian Church. This article explores how Halloween emerged from Christian theology, particularly concepts of the afterlife, and how its historical development in Ireland reflects the influence of Christian observances rather than pagan traditions.
The Establishment of All Saints' and All Souls' Day
All Saints' Day: Honoring the Christian Martyrs
All Saints' Day, also known as All Hallows' Day, was instituted to honor all Christian saints, particularly those who had been martyred for their faith. The earliest recorded observance of a collective feast for saints dates back to May 13, 609 AD, when Pope Boniface IV consecrated the Pantheon in Rome to the Virgin Mary and all martyrs. However, in the Celtic regions, particularly Ireland, the feast was originally celebrated in April, aligning with local traditions.
It was Pope Gregory III (731–741 AD) who officially moved the date to November 1st, likely to align with existing Christian commemorations in northern Europe, particularly among the Germanic peoples who had long observed All Saint's Day on that date, rather than with regional customs in Celtic Irland. This shift established the foundation for what would later become Halloween. (1, 2)
All Souls' Day: Prayers for the Departed
Following All Saints' Day, All Souls' Day was introduced as a day of prayer for the faithful departed, particularly those believed to be in purgatory. The observance was formalized by Odilo of Cluny in 998 AD, and by the 13th century, it had become a universal practice in the Christian Church. The theological basis for All Souls' Day is rooted in the belief that prayers and masses offered by the living can aid the souls of the deceased in their journey toward heaven.
The Emergence of Halloween in Christian Tradition
The Influence of All Hallows' Eve
The evening before All Saints' Day, known as All Hallows' Eve, gradually became a significant observance. The term "Halloween" itself derives from "Hallowe'en," meaning "Hallows' Evening." As Christian communities prepared for the solemnity of All Saints' Day, traditions of vigils, prayers, and remembrance of the dead became widespread. For reference, that means Allhallowtide—comprised of the three feast days—was being observed across the church for roughly 300 years before the Great Schism or Roman Catholic/Orthodox distinctions ever existed, and 800 years before the Protestant Reformation. It is therefore inaccurate to say that these traditions are "Catholic" or to dismiss them on those grounds, since such distinctions did not exist at the time and would not exist for centuries.
The Role of Irish Christianity
Ireland played a crucial role in shaping Halloween as we know it today. The Irish Christian tradition emphasized prayers for the dead, and customs such as lighting candles, visiting graves, and offering food to the poor were common practices. These customs were later carried to other parts of Europe and, eventually, to North America.
Debunking the Pagan Myth: The Earliest Sources on Samhain
One of the most persistent misconceptions about Halloween is its alleged connection to Samhain, a Celtic festival marking the end of the harvest season. While Samhain was indeed observed in ancient Ireland, the earliest records of Samhain do not describe it as a religious or spiritual festival.
Historical sources indicate that Samhain was primarily a seasonal marker, signifying the transition from summer to winter. The notion that Samhain was a "pagan festival of the dead" is largely a modern reinterpretation, rather than an accurate reflection of early Celtic practices. (3)
The earliest references to Samhain appear in 9th-century Irish literature, specifically Tochmarc Emire (The Wooing of Emer) from the Ulster Cycle, where it is described as a time of great gatherings and feasts. (4, 5) These texts associate Samhain with the ancient burial mounds—later reimagined as fairy mounds (síde)—believed to be portals into the Otherworld, the realm of the fairy folk. However, they do not explicitly mention costumes, bonfires, spirits of the dead, or dancing.
Later sources, such as Geoffrey Keating's 17th-century History of Ireland, describe bonfires and animal sacrifices, but these accounts were written centuries after the original Celtic practices. The idea that Samhain involved dressing up to ward off spirits appears to be a later interpretation, possibly influenced by medieval Christian traditions rather than pre-Christian Celtic customs.
The Modern Evolution of Halloween in North America
While Halloween has Christian roots, many of the traditions we associate with it today—such as trick-or-treating, pumpkin carving, haunted houses, and elaborate costumes—are relatively modern developments that originated in North America rather than ancient Celtic or medieval Christian traditions. (6)
Trick-or-Treating: Became widespread in the 1920s and 1930s, influenced by earlier European traditions of "souling" and "guising."
Pumpkin Carving: Irish immigrants adapted their tradition of carving turnips into pumpkins, which were more abundant in North America.
Haunted Houses: Commercial haunted attractions emerged in the 1970s, becoming a staple of modern Halloween celebrations.
Costumes: While dressing up has medieval Christian roots, the elaborate costumes we see today are largely a modern phenomenon, influenced by Hollywood and consumer culture.
Conclusion: Halloween as a Christian Tradition
Far from being a pagan festival, Halloween is deeply rooted in Christian theology. The observance of All Saints' Day and All Souls' Day provided the framework for remembering the dead, praying for souls in purgatory, and celebrating the victory of the saints in heaven. The customs associated with Halloween—such as lighting candles, dressing in costumes, and offering food—can be traced to Christian practices rather than pre-Christian rituals.
Understanding Halloween through a Christian lens allows us to appreciate its theological significance and historical development. Rather than dismissing it as a pagan holiday, we should recognize it as a reflection of Christian beliefs about the afterlife, the communion of saints, and the hope of resurrection.

While this article raises some valid points about All Saints’ and All Souls’ Day, it overlooks substantial evidence that Halloween’s origins are syncretic—a fusion of Christian and pre-Christian Celtic traditions.
Samhain, far from being a mere “seasonal marker,” was the most important festival in the early Celtic calendar, marking the end of harvest and the beginning of winter. Both archaeological and literary evidence link it to rituals involving bonfires, feasting, and beliefs about the dead and the Otherworld. (See Ronald Hutton, The Stations of the Sun: A History of the Ritual Year in Britain, Oxford University Press, 1996, pp. 360–368.)
When Pope Gregory III moved All Saints’ Day to November 1 in the 8th century, it almost certainly coincided intentionally with these local observances—a strategy the Church often used to Christianize existing pagan festivals. (Nicholas Rogers, Halloween: From Pagan Ritual to Party Night, Oxford University Press, 2002, pp. 25–30.)
Medieval Irish and Scottish customs such as guising, lighting bonfires, and offering food to wandering souls show clear continuity from pre-Christian Samhain to Christian All Hallows’ Eve traditions. These are documented well into the early modern period. (See W.J. Hoffman, “Popular Beliefs and Customs in Celtic Countries,” Folklore, vol. 2, no. 1, 1891; and J. Carmichael, Carmina Gadelica, 1900.)
Thus, while the name “Halloween” and some theological framing come from Christianity, many of the folk practices long predate it. To present Halloween as purely Christian ignores this deep cultural blending that shaped the holiday over centuries.
In short, Halloween is neither wholly pagan nor wholly Christian—it’s both, a product of cultural synthesis between Celtic seasonal rites and Christian commemoration of the dead.

Thank you for this thoughtful engagement and for citing some of the key works in the field. I agree that cultural blending is part of the story—Christian feasts often absorbed or coincided with local seasonal observances. That said, my article’s focus was on the theological framework of All Saints’ and All Souls’ Day, which is well documented in early church history, rather than on cataloging specific folk traditions.
The sources you cite are important contributions, but they also illustrate the limits of what we can know. Ronald Hutton, for example, emphasizes Samhain’s role as a seasonal marker and its later folklore associations, but he is cautious about calling it a “festival of the dead” in pre‑Christian times. Nicholas Rogers raises the possibility that Gregory III’s November 1 date overlapped with local observances, but the November 1 feast was already established in Germanic regions, while Celtic Christians had long observed All Saints’ in April—making it more likely that Gregory was harmonizing with the Germanic church rather than targeting Samhain. And much of the evidence for “continuity” comes from later folklore collections (e.g., Carmichael, Hoffman) in the 18th–19th centuries, which are valuable for folk history but cannot be projected backward as proof of ancient Celtic ritual. Earlier works like MacCulloch’s Religion of the Ancient Celts are also highly interpretive reconstructions rather than direct evidence.
Additionally, some of the supposed “continuities” are shakier than they first appear. Bonfires, for instance, are a widespread communal practice across many cultures, so their presence in both Celtic and Christian contexts doesn’t prove direct pagan continuity. Likewise, guising and food offerings are well attested in the medieval and early modern periods, but tracing them securely back to pre‑Christian Samhain is speculative.
So, while I don’t deny that syncretism played a role, the stronger historical through‑line is the Christian liturgical calendar, which shaped the observance centuries before the modern holiday took its current form. Many of the practices we now associate with Halloween—trick‑or‑treating, pumpkin carving, haunted houses—are relatively recent, originating in North America. These reflect a synthesis of customs from multiple cultures rather than continuity from any single pre‑Christian belief, which makes it difficult to definitively connect modern Halloween traditions to an ancient pagan source. That’s at least how I read the evidence, though I recognize others interpret it differently.
All this does go a bit beyond the intended scope of my article, but it may be worth exploring in a future installment—so thank you again for the engagement and the inspiration.
