What Is All Saints’ Day?

All Saints’ Day is a Christian holy day celebrated on November 1st in Western Christianity, and on the first Sunday after Pentecost in Eastern Christianity. The day is set aside to honor and remember all saints, both known and unknown, who have lived lives of exemplary faithfulness and devotion to God. This includes not only canonized saints but also all Christians who have passed away and are believed to be in heaven.

Here are key aspects of All Saints’ Day:

The origins of All Saints’ Day can be traced back to the early Christian church. Initially, martyrs who died for their faith were honored on specific days. As the number of martyrs grew, the church began to designate a single day to commemorate all the saints. Pope Gregory III (731–741 AD) moved the date to November 1st during his reign, dedicating a chapel in St. Peter’s Basilica to “all saints.” The celebration was extended to the entire church by Pope Gregory IV in 837 AD.

All Saints’ Day is an opportunity to celebrate the communion of saints—the belief that all of God’s people, both the living and the dead, are spiritually connected in Christ. Christians honor those who have faithfully followed Christ and have gone before them into eternal life. It’s a time to remember the example of these saints, their virtues, and their contribution to the faith.

Many Christian denominations, including Roman Catholic, Anglican, Lutheran, and some Protestant churches, hold special services on All Saints’ Day. In these services, congregants often read the names of those in the community who have passed away, lighting candles in their memory.

In some cultures, people visit cemeteries and decorate the graves of their loved ones with flowers, candles, and prayers, especially on the evening of October 31st (All Hallows’ Eve, which evolved into Halloween).

The liturgy often focuses on the themes of resurrection, eternal life, and the victory of Christ over death. The scriptures read typically emphasize the blessedness of the saints, including readings from the Sermon on the Mount (Matthew 5:1-12) or passages from Revelation describing the heavenly hosts.

All Saints’ Day is closely followed by All Souls’ Day on November 2nd, which is dedicated to praying for the souls of all the faithful departed, particularly those undergoing purification in Purgatory (in Roman Catholic teaching). While All Saints’ Day celebrates those who have already reached heaven, All Souls’ Day is a day of remembrance and intercession for those who are not yet fully purified.

All Saints’ Day is celebrated across a variety of Christian traditions, but it holds particular importance in the Roman Catholic, Eastern Orthodox, Anglican, and Lutheran churches. The day also varies in its observance depending on cultural and regional traditions. In countries like Mexico, it overlaps with the Día de los Muertos (Day of the Dead) celebrations, where people honor both saints and deceased family members.

In some countries, All Saints’ Day is a public holiday (such as in many European nations), while in others, it is more of a religious observance. Churches may host special prayers or memorials for deceased church members. Many Christians also take this time to reflect on the legacies of their ancestors in the faith and to consider how they themselves are living in light of eternity.

All Saints’ Day, then, is a celebration of the faithfulness of those who have gone before in the Christian faith, offering an opportunity to reflect on their lives as examples of devotion and to honor their memory. It also provides comfort to the living, affirming the Christian belief in the communion of saints and the hope of eternal life.
