Every October, many Christian families face the same question: Is Halloween really the devil's holiday? The short answer is no, not historically. Halloween has a complicated history. Ancient Celtic customs influenced its development, but Christianity also profoundly shaped the holiday. In fact, the word "Halloween" comes from All Hallows' Eve, the evening before the Christian celebration of All Saints' Day. Britannica describes Halloween as the evening before the Western Christian feast of All Saints and notes that its history contains both Celtic and Christian elements.
Its reputation as something sinister largely stems from modern cultural anxieties and misunderstandings of its origins. That does not mean Christians should embrace everything associated with modern Halloween. Occult practices, glorifying evil or treating demonic imagery as harmless entertainment can raise legitimate spiritual concerns. But calling October 31 simply "the devil's holiday" overlooks centuries of history and, more importantly, its place beside two important Christian observances.
Halloween's Ancient Roots: The Celtic Festival of Samhain
Part of Halloween's story begins with Samhain, an ancient Celtic festival that marked an important seasonal transition. Britannica explains that the festival was observed in ancient Britain and Ireland and was connected with the beginning of a new year, the harvest and preparations for winter. Celtic beliefs also associated this period with supernatural activity.
Bonfires and disguises became associated with the festival. The Library of Congress likewise connects Halloween with Samhain, describing it as a pagan religious celebration in which people lit bonfires and wore costumes to ward off ghosts. These facts help explain why Halloween eventually became associated with ghosts, darkness, costumes and the dead. Still, Halloween developed over many centuries as different religious and cultural traditions interacted, so we should avoid the overly simple argument that today's Halloween is merely Samhain with a new name.
How Christianity Shaped All Hallows' Eve
Christianity gave October 31 a very different framework. The Church developed a celebration honoring the saints. The Library of Congress says that in the eighth century, Pope Gregory III designated November 1 as a time to honor saints. The evening before All Saints' Day came to be known as All Hallows' Eve, which eventually became "Halloween." "Hallows" means saints or holy ones, so the very name Halloween has a Christian connection.
Britannica notes that Halloween developed partly from Samhain but also significantly from medieval Christian feasts of the dead, including All Saints' Day. So rather than seeing October 31 only through images of ghosts and monsters, Christians can remember what follows it: the celebration of the saints.
Halloween, All Saints' Day and All Souls' Day
For Christians, especially Catholics, Halloween can make more sense when we look at three consecutive days rather than October 31 alone. October 31 is All Hallows' Eve. November 1 is All Saints' Day, and November 2 is All Souls' Day, the Commemoration of All the Faithful Departed.
Pope Gregory III designated November 1 as All Saints' Day, also called All Hallows' Day, to honor all saints and martyrs. On All Saints' Day, Christians celebrate holiness and those who have gone before us in faith. In a 2023 Angelus address, Pope Francis described holiness as both a gift from God and a journey. He encouraged Christians to see the saints as examples and companions in the Christian life.
St. Odilo of Cluny, Benedictine abbot of the influential Abbey of Cluny in France, designated November 2 as All Souls' Day. All Souls' Day turns attention toward prayer for the dead. Vatican News notes that Christians have been praying for their departed loved ones since the second century. November 2 eventually became the Church's formal day of remembrance for the faithful departed. This gives Christians a different way to approach Halloween.
Halloween does not have to point Christians toward darkness. Set beside All Saints' Day and All Souls' Day, it can point beyond darkness toward holiness, remembrance, resurrection and the victory of Christ.
Other Christian Views of All Saints' Day and All Souls' Day
While All Saints' Day and All Souls' Day originated in the Western Catholic tradition, other Christian branches observe them in their own ways.
Lutheran, Anglican, Methodist and Presbyterian Churches
Many mainline Protestant denominations formally recognize All Saints' Day, often on the first Sunday in November rather than strictly on November 1, though their theology differs from that of Catholicism.
All Saints' Sunday: Protestants generally view all Christian believers as "saints" in the biblical sense, rather than as a special tier of canonized individuals. Services often focus on thanking God for the "whole communion of saints" and remembering members of the local congregation who died in the past year. It is common to read their names aloud, toll a bell and light candles.
All Souls' Day: Because traditional Protestant theology rejected the concept of purgatory, which All Souls' Day was originally designed to address through prayers for the dead, strict observance of November 2 faded during the Reformation. However, many Anglican and Lutheran churches have revived a modified version — often called the Commemoration of the Faithful Departed — that focuses on grief, thanksgiving and the resurrection rather than intercessory prayer for souls in purgatory.
Eastern Orthodoxy
The Eastern Orthodox Church does celebrate All Saints, but at a completely different point in the calendar. Instead of November, Orthodox Christians celebrate All Saints' Sunday on the first Sunday after Pentecost, usually in late spring or early summer.
For the Orthodox, grouping all saints at the end of the Paschal and Pentecost seasons emphasizes that holiness is the goal of the entire Church. They also set aside "Soul Saturdays" throughout the year for the general remembrance of the departed.
Evangelical and Nondenominational Churches
Evangelical, Baptist and nondenominational Protestant churches typically do not observe All Saints' Day or All Souls' Day. Because these traditions emphasize local church autonomy and stand apart from historical liturgical calendars, these feast days are rarely mentioned. Instead, many Protestant churches in this sphere emphasize Reformation Day on October 31 to commemorate the beginning of the Protestant Reformation in 1517.
The Christian Approach
Jesus teaches us not to judge others (Matthew 7:1-2). This is especially important on Halloween, as many people still view the day as a celebration that goes against their faith. Romans 14:5-6 teaches that each day is to be honored in the Lord, and we should give Him thanks. We are asked to respect others' choices, whether we agree with them or not. Matthew 5:14-16 reminds us to "let your light shine before others" and give glory to the Father.
Halloween was never a celebration of Satan. Instead, it evolved as a playful, communal way to confront mortality, mark the changing of the seasons and enjoy a night of community fun. Some costumes, decorations and other elements may be disturbing to children, so take time to explain the true meaning of Halloween and its origins to your kids, including anything that goes against your family's faith.
History does not support labeling Halloween simply as "the devil's holiday." Its development combines ancient Celtic influences, centuries of Christian observance, folk traditions, immigration and modern secular customs. You can teach your children about the saints, pray for deceased relatives, visit a cemetery, attend Mass or another church service, and remember the Christian hope of eternal life. For many Christians, October 31 can also serve as the doorway into All Saints' Day and All Souls' Day. In the end, Halloween need not be feared or dismissed. Celebrate the day with discernment, and let your light glorify the Lord.
