It is therefore a holy and wholesome thought to pray for the dead, that they may be loosed from sins (II Maccabees 12:46).
This verse tells us that sins can be forgiven after death by the intercession of prayers of those who still live.
St. Paul through the Holy Ghost tells us in the Apocalypse the defiled will not enter Heaven. [1] Yet, all good men are defiled in someway. There may be an attachment to sin even through ignorance and the punishment due to forgiven mortal sin. Men don’t always repair and make restitutions for their sins, which is a type of defilement. Therefore, a place of purgation and purification must exist in order that God’s justice and mercy apply perfectly and completely. How this works is explained in St. Paul’s Letter to the Corinthians.
9 For we are God’s coadjutors: you are God’s husbandry; you are God’s building.
10 According to the grace of God that is given to me, as a wise architect, I have laid the foundation; and another buildeth thereon. But let every man take heed how he buildeth thereupon. 11 For other foundation no man can lay, but that which is laid; which is Christ Jesus. 12 Now if any man build upon this foundation, gold, silver, precious stones, wood, hay, stubble: 13 Every man’s work shall be manifest; for the day of the Lord shall declare it, because it shall be revealed in fire; and the fire shall try every man’s work, of what sort it is. 14 If any man’s work abide, which he hath built thereupon, he shall receive a reward. 15 If any man’s work burn, he shall suffer loss; but he himself shall be saved, yet so as by fire. 16 Know you not, that you are the temple of God, and that the Spirit of God dwelleth in you?
17 But if any man violate the temple of God, him shall God destroy. For the temple of God is holy, which you are (I Cor. 3:9-17).
The “day of the Lord” is Judgment Day. The temple is man. Gold, silver, and precious stones represents good works deserving of a reward (Heaven). Wood, hay, and stubble represents venial sins, which gets burned up (Purgatory). Violating the temple is mortal sin and those that do so will be destroyed (Hell).
Mortal sins are sins unto death, and venial sins are sins not unto death (First John 5:16-17). For instance, in Matthew 5:19, Jesus states that men can commit certain sins and even teach others to commit that sin but would be called least in the Kingdom of Heaven. Other sins however, Jesus says would cause men liable to hell fire. Therefore, different types of sins have different types of punishment and this is what St. Paul describes.
Lastly, Jesus implicitely tells that Purgatory exists:
“And whosoever shall speak a word against the Son of man, it shall be forgiven him: but he that shall speak against the Holy Ghost, it shall not be forgiven him, neither in this world, nor in the world to come (Matt. 12:32).”
Fr. Leo Haydock writes in his Bible commentary that St. Augustine (De Civ. 1.xxi. c. 13) and Pope St. Gregory the Great (Dial. Iv, c. 39) understood the passage to refer to Purgatory. “St. Augustine said this passage would not be true, if some sins were not forgiven in the world to come; and St. Gregory says, we are to believe from these words in the existence of the fire of purgatory, to expiate our smaller offenses, before the day of judgment. St. Isidore and Ven. Bede say the same. St. Bernard, speaking of heretics, says they do not believe in purgatory; let them then inquire of our Savior, what he meant by these words.” [2]
Fr. Cornelius à Lapide S.J. writes in his commentary, “S. Aug. (21 Civit. 24), S. Greg. (4 dialog. 39), Isidore, Bede, S. Bern., and others, quoted by Bellarmine (Lib. 2. de Purgat. sec. 4), prove from this passage, that there is a Purgatory after this life. For it would be unmeaning to say, shall not be forgiven nor in the world to come, if there were no remission of sins in the world to come. Thus a person would speak vainly who said, I will never marry a wife, neither in this world, nor in the world to come, since no wife can be married in the world to come. Mark adds, and gives greater force to the saying: but shall be guilty of eternal damnation. Moreover mortal sins are expiated in Purgatory, so far only as pertains to their punishment, but venial sins as regards both fault and punishment.” [3]
In the past, I’ve answered certain objections to Purgatory, [4] but the bottom line is that the Church is the pillar and ground for the truth (I Tim. 3:15) and the Church from its beginning has believed in Purgatory. We clearly see it in the Holy Bible. According to Apostolic traditions, liturgies were offered for the poor souls in Purgatory. We also see prayers offered for the dead in the catacombs.
The 3rd century heretics known as the Apostolici (a sect of Encratites) denied Purgatory, but could not have done so if the universal belief didn’t already exist.
Later heretics such as the Cathars (Waldenses) of the 12th century denied the existence of Purgatory. Some of the Eastern Orthodox (Greek and Russian) denied it after the “Orthodox Confession of Petrus Mogilas” was drawn up around 1640 AD. The Protestants denied it in the 16th century. The fact that they all denied Purgatory demonstrates that it existed before they existed.
The 2nd Council of Lyons (1274), Pope Benedict XII, in the dogmatic constitution “Benedietus Deus” (1336), Council of Florence (1439), and the Council of Trent (1563) defined Purgatory from a universal belief to a dogma of the Catholic Faith. [5]
God has spoken and His Church, the Pillar and Ground for the truth has spoken. Purgatory is real!
