In a recent meeting of our weekly Catholic Study Group, the topic of Purgatory was broached, specifically the topic of the fires and pain of Purgatory. One member suggested that we consult the saints about this.
The Scriptures
The concept of purgatorial fire emerges from scriptural passages like 1 Corinthians 3:11–15 which describes works being tested by fire, with the builder saved “as through fire.” Other texts, such as Matthew 5:25–26 (settling debts to avoid prison) and 2 Maccabees 12:38–46 (prayers for the dead), support purification without specifying fire. Many more scriptural warrants for belief in Purgatory may be found in St. Robert Bellarmine’s “On Purgatory.”
St. Cyprian of Carthage
One early reference to Purgatory can be found in the writings of St. Cyprian of Carthage (210-258 AD) in his Epistle 51. There he compares a soul going to Purgatory to a soul going straight to heaven:
It is one thing to stand for pardon, another thing to attain to glory: it is one thing, when cast into prison, not to go out thence until one has paid the uttermost farthing; another thing at once to receive the wages of faith and courage. It is one thing, tortured by long suffering for sins, to be cleansed and long purged by fire; another to have purged all sins by suffering. It is one thing, in fine, to be in suspense till the sentence of God at the day of judgment; another to be at once crowned by the Lord.
He is clearly telling believers to avoid Purgatory if they can.
St. Gregory of Nyssa
St. Gregory of Nyssa (335-394 AD) and St. Augustine (354-430 AD) explicitly used fire metaphors to convey the intensity of purification. In his dialogue On the Soul and the Resurrection (c. 382), he explains the afterlife’s “punishment by fire” as a divine process to eradicate evil from the soul. He uses the metaphor of refining gold:
“Just as those who refine gold from the dross which it contains not only get this base alloy to melt in the fire, but are obliged to melt the pure gold along with the alloy, and then while this last is being consumed the gold remains, so, while evil is being consumed in the purgatorial fire, the soul that is welded to this evil must inevitably be in the fire too, until the spurious material alloy is consumed and annihilated by this fire.“
St. Augustine
Augustine explicitly addressed the idea of a cleansing after death in the 69th chapter of his Enchiridion (Handbook on Faith, Hope, and Love), where he wrote:
And it is not impossible that something of the same kind may take place even after this life. It is a matter that may be inquired into, and either ascertained or left doubtful, whether some believers shall pass through a kind of purgatorial fire, and in proportion as they have loved with more or less devotion the goods that perish, be less or more quickly delivered from it.
In his Expositions on the Psalms, St. Augustine said:
“O Lord, rebuke me not in Your indignation; neither chasten me in Your hot displeasure.” Psalm 37:1. For it will be that some shall be chastened in God’s hot displeasure, and rebuked in His indignation. And haply not all who are rebuked will be chastened; yet are there some that are to be saved in the chastening. So it is to be indeed, because it is called chastening, but yet it shall be so as by fire.
St. Thomas Aquinas
St. Thomas Aquinas composed his great work, the Summa Theologiae, over approximately eight years, beginning around 1265–1266 while in Rome and continuing until 1273. In the Summa’s Appendix I, Question 2, Article 1, St. Thomas said:
In Purgatory there will be a twofold pain; one will be the pain of loss (poena damni), namely the delay of the divine vision, and the pain of sense (poena sensus), namely punishment by corporeal fire. With regard to both the least pain of Purgatory surpasses the greatest pain of this life. For the more a thing is desired the more painful is its absence. And since after this life the holy souls desire the Sovereign Good with the most intense longing—both because their longing is not held back by the weight of the body, and because, had there been no obstacle, they would already have gained the goal of enjoying the Sovereign Good—it follows that they grieve exceedingly for their delay. …the pain of Purgatory, both of loss and of sense, surpasses all the pains of this life.
St. Catherine of Genoa
St. Catherine of Genoa (1447-1510) was an Italian mystic and is particularly famous for her writings on Purgatory in her Treatise on Purgatory (Brittanica Editors). She wrote about poignantly about poena damni in that work:
the souls of the faithful are placed in purgatory to get rid of all the rust and stain of sin that in this life was left unpurged. (St. Catherine of Genoa 1)
No tongue can express, no mind can understand, how dreadful is purgatory. Its pain is like that of hell and yet (as have said) see any soul with the least stain of imperfection accept it as mercy, not thinking it of any moment when compared with being kept from its Love. It appears to me that the greatest pain the souls in purgatory endure proceeds from their being sensible of something in themselves displeasing to God, and that it has been done voluntarily against so much goodness for, being in state of grace, they know the truth, and how grievous is any obstacle which does not let them approach God. (St. Catherine of Genoa 11)
this sense of the grievousness of being kept from beholding the Divine light, coupled with that instinctive longing which would fain be without hindrance to follow the enticing look, these two things, say, make up the pains of the souls in purgatory. (St. Catherine of Genoa 13)
A little about poena damni
If “poena damni” or “punishment of loss” seems too mild to you, you might want to reflect on the terrible losses experienced by some here on earth, such as the searing pain that comes with the loss of a child. Consider that loss, and turn the dial up toward infinity and you’ll approach the sense of loss experienced by the saved in Purgatory.
St. Faustina Kowalska
St. Faustina Kowalska (1905–1938) wrote extensively about her visions of Purgatory in her diary, Divine Mercy in My Soul. She describes it as a misty place full of fire and suffering souls, whose greatest torment is their intense longing for God. She also records seeing her Guardian Angel lead her there and the Blessed Virgin Mary bringing refreshment to the souls.
Here is her most well-known passage regarding Purgatory:
“The next night] I saw my Guardian Angel, who ordered me to follow him. In a moment I was in a misty place full of fire in which there was a great crowd of suffering souls. They were praying fervently, but to no avail, for themselves; only we can come to their aid. The flames which were burning them did not touch me at all. My Guardian Angel did not leave me for an instant. I asked these souls what their greatest suffering was. They answered me in one voice that their greatest torment was longing for God. I saw Our Lady visiting the souls in Purgatory. The souls call her “The Star of the Sea.” She brings them refreshment. I wanted to talk with them some more, but my Guardian Angel beckoned me to leave. We went out of that prison of suffering. [I heard an interior voice] which said, My mercy does not want this, but justice demands it. Since that time, I am in closer communion with the suffering souls.” (Kowalska 20)
Many more examples of saintly visions of Purgatory may be found in Fr. Francis Schouppe’s book, “Purgatory: Explained by the Lives and Legends of the Saints,” available from Tan Books.
Key Conciliar Teachings on Purgatory
How has the Church officially described the pains of Purgatory?
The doctrine of purgatory was formally defined by ecumenical councils in response to theological controversies. These councils include the Second Council of Lyons (1274), the Council of Florence (1438–1445), and the Council of Trent (1545–1563). None of these councils use the specific phrase “fires of purgatory” or equate the purification explicitly with fire. Instead, they emphasize the purifying nature of the punishments and the efficacy of suffrages (prayers, Masses, alms) from the living to aid the souls there.
In the profession of faith presented by Emperor Michael VIII Palaeologus and incorporated into the acts of the Second Council of Lyon (1274), purgatory is described as involving “purgatorical or purifying punishments” for souls who die repentant but without full satisfaction for their sins. These souls benefit from the “sacrifices of Masses, prayers, alms, and other duties of piety.” (The Sources of Catholic Dogma 184) Earlier papal documents around the time, e.g., a 1254 letter from Innocent IV, refer to a “transitory fire” in explaining purgatory to the Greeks. This was not a conciliar decree, however. (The Sources of Catholic Dogma 180-181)
The Council of Florence (1438–1445), aimed at union with the Eastern Churches, defined purgatory in its Decree for the Greeks (Session 6, 1439) as a process where “souls are cleansed after death by purgatorial punishments” (or “cleansing pains” in some translations), and suffrages from the faithful help release them. The decree stresses that this purification applies to those who die in God’s love but have not fully atoned for sins through penance. Again, fire is not mentioned in the text. (The Sources of Catholic Dogma 219-220)
The Council of Trent (1545–1563) responded to Protestant denials of Purgatory in its Decree Concerning Purgatory (Session 25, 1563) which reaffirmed that “there is a purgatory, and that the souls there detained are helped by the suffrages of the faithful, but principally by the acceptable sacrifice of the altar.” Bishops are instructed to teach this doctrine based on Scripture, the Fathers, and prior councils, while avoiding “difficult and subtle questions” that do not edify the faithful or that foster superstition. Trent cites no specific fire reference. (The Sources of Catholic Dogma 298)
Conclusion
We are bound to believe in the reality of Purgatory as a place or state where saved souls are purged of their repented sin and cleansed for heaven. The Magisterial teaching of the councils, along with the writings of the saints, seem to allow us some freedom of belief in the nature of the pains and fires of Purgatory. We can believe that the fire of Purgatory is physical or metaphorical, but in any case, the consensus seems to be that the pain of purgatory is primarily that of a temporary deprivation of the sight of God, the Supreme Good, the Beatific Vision. This pain is intense and is far greater than any pain that can be experienced on earth and it should be avoided.
