The Souls in Purgatory: A Catholic Understanding
The doctrine of Purgatory reflects the belief in God’s merciful justice—a state where souls, although assured of salvation, undergo purification before entering the brightness of eternity. Rooted in Scripture, the concept of Purgatory assures the faithful that even after death, God’s love continues to purify and prepare the soul to stand fully in His presence.
The Bible includes references that indirectly point to this purifying state. In 2 Maccabees 12:46, for instance, it states, “It is a holy and wholesome thought to pray for the dead, that they may be loosed from sins.” Our prayers can aid the deceased. The New Testament also reflects this idea; in 1 Corinthians 3:15, St. Paul speaks of a “fire” through which a person is saved, but “as through fire,” which the Church understands as an allusion to purification.
Saints and Church Fathers developed this understanding further. St. Augustine, for example, discussed how certain sins could be purified after death, a process that assists souls on their path to heaven. St. Gregory the Great also spoke of Purgatory as a merciful gift from God, allowing souls to become fully sanctified. In his Dialogues, he even recounts stories of souls who appeared to the living to request prayers for their speedy release from Purgatory.
The theologian St. Thomas Aquinas later offered a more systematic explanation. He explained that Purgatory is both a place of purification and a manifestation of God’s mercy, designed to ready the soul for the Beatific Vision. According to Aquinas, Purgatory is not punishment in the punitive sense but rather a purgative process meant to prepare us for divine union with God.
Devotion to the souls in Purgatory has long been a practice of the Catholic Church, spurred on by the understanding that the living can aid these souls through prayer, fasting, and almsgiving. The Commemoration of All Souls, kept on November 2, honors the departed and encourages prayers for those in Purgatory. Numerous saints, including St. Gertrude the Great and St. Catherine of Genoa, had visions of the suffering souls and spoke fervently of the importance of interceding for them.
The Story of Our Lady of Knock

In 1879, the small village of Knock, County Mayo, Ireland, became the site of one of the most renowned Marian apparitions in modern history. On the rainy evening of August 21, fifteen villagers witnessed a unique apparition on the gable wall of the local parish church. They saw not only the Blessed Virgin Mary but also St. Joseph, St. John the Evangelist, and, notably, an altar with a lamb and a cross, symbolizing Christ as the “Lamb of God.”
This apparition stands out because Our Lady did not speak, and the vision seemed to encapsulate a message in its symbolism rather than in words. Catholic scholars and historians have offered numerous interpretations of this silent yet profound vision. Some suggest that it was a message of hope and consolation for the Irish people, who were suffering from poverty, religious oppression, and a recent famine. Certainly, it was an invitation to deeper faith, urging a devotion to Christ, the Most Holy Eucharist, and His Mother, Mary.

Fr. Francis Duffy, a prominent priest and scholar, explained that Knock represents an invitation to pray and intercede, particularly for the souls in Purgatory. The presence of the Lamb of God on an altar suggests a Eucharistic connection, linking Knock to the ongoing sacrifices offered for the purification of souls. Scholars have noted that the Irish people’s deep devotion to the souls in Purgatory intensified after the apparition, seeing in it a call to remember the deceased and assist them in their journey to heaven.
The Connection Between Knock and the Souls in Purgatory
The devotion to Our Lady of Knock has often been linked to intercession for the souls in Purgatory. Since the apparition, Knock has become a place of pilgrimage, where many come to pray for the dead, asking Our Lady to intercede for their loved ones in Purgatory. This link is particularly strong in Ireland, where belief in Purgatory has always been deeply ingrained.

One of the most intriguing aspects of the Knock apparition is its silent nature. The silence seems to convey a profound mystery and an invitation to contemplation, an opportunity to pray and offer penance for the deceased. The image of the Lamb on the altar resonates with Catholic teaching on the Mass as a sacrifice, the re-presentation of Christ’s sacrifice on Calvary. Many who visit Knock view it as an ideal place to offer Masses for the repose of the souls in Purgatory.
Historian and theologian Rev. John MacPhilbin has written about how the Irish faithful have long had a special love for the Poor Souls, perhaps due to Ireland’s own long history of suffering and endurance. MacPhilbin notes that “the Irish people, bearing witness to their own trials, naturally turn to Our Lady as both a comfort and a hope for those still undergoing their purgation.” This reverence is evident in the continuous stream of pilgrims who come to Knock, often bearing Mass intentions for loved ones who have passed.
