The Doctrine of Purgatory
Compendium of the Catechism of the Catholic Church
194. What is the meaning of the “communion of saints”?
946-953
960
This expression indicates first of all the common sharing of all the members of the Church in holy things (
sancta): the faith, the sacraments, especially the Eucharist, the charisms, and the other spiritual gifts. At the root of this communion is love which “does not seek its own interests” (
1 Corinthians 13:5) but leads the faithful to “hold everything in common” (
Acts 4:32), even to put one’s own material goods at the service of the most poor.
195. What else does “the communion of saints” mean?
954-959
961-962
This expression also refers to the communion between holy persons
(sancti); that is, between those who by grace are united to the dead and risen Christ. Some are pilgrims on the earth; others, having passed from this life, are undergoing purification and are helped also by our prayers. Others already enjoy the glory of God and intercede for us. All of these together form in Christ one family, the Church, to the praise and glory of the Trinity.
210. What is purgatory?
1030-1031
1054
Purgatory is the state of those who die in God’s friendship, assured of their eternal salvation, but who still have need of purification to enter into the happiness of heaven.
211. How can we help the souls being purified in purgatory?
1032
Because of the communion of saints, the faithful who are still pilgrims on earth are able to help the souls in purgatory by offering prayers in suffrage for them, especially the Eucharistic sacrifice. They also help them by almsgiving, indulgences, and works of penance.
The Witnesses of Purgatory
Judaism
Jews in Jesus' time believed that souls who died went to Sheol or Hades, where they were divided: One group were those who would suffer in hell for eternity, another group were those who would suffer in hell temporally. It was believed that prayer could help the latter and that the Messiah would release them when he comes to usher in a time of peace and justice.
Scripture
Jesus uses the belief of temporal suffering in hell twice: Once in a parable about a merciless servant and another time when he says there are some who are neither forgiven in this age or the next age. The parable illustrates punishment in a dungeon until the last penny is paid to the king - an imagery used by the Church Fathers to refer to Purgatory - and Jesus' words on the next age illustrates forgiveness of sins after death - also used by the Church Fathers to refer to Purgatory.
Tradition
According to Sacred Tradition, Purgatory is like a dungeon where souls go to suffer temporally for their sins, being purged by their suffering, and after which they enter Heaven in clean linen robes. Besides the dungeon, other images for Purgatory include a prison, fire and smoke, a shower, a type of confessional, and a mountain.
Church Fathers
Cyprian
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 (Letters 51[55]:20 [A.D. 253]).
Then we make mention also of those who have already fallen asleep: first, the patriarchs, prophets, apostles, and martyrs, that through their prayers and supplications God would receive our petition, next, we make mention also of the holy fathers and bishops who have already fallen asleep, and, to put it simply, of all among us who have already fallen asleep. For we believe that it will be of very great benefit to the souls of those for whom the petition is carried up, while this holy and most solemn sacrifice is laid out (Catechetical Lectures 23:5:9 [A.D. 350]).
Let us help and commemorate them. If Job's sons were purified by their father's sacrifice [Job l:5), why would we doubt that our offerings for the dead bring them some consolation? Let us not hesitate to help those who have died and to offer our prayers for them (Homilies on First Corinthians 41:5 [A.D. 392]).
Not in vain was it decreed by the apostles that in the awesome mysteries remembrance should be made of the departed. They knew that here there was much gain for them, much benefit. When the entire people stands with hands uplifted, a priestly assembly, and that awesome sacrificial victim is laid out, how, when we are calling upon God, should we not succeed in their defense? But this is done for those who have departed in the faith, while even the catechumens are not reckoned as worthy of this consolation, but are deprived of every means of assistance except one. And what is that? We may give alms to the poor on their behalf (Homilies on Philippians 3:9-10 [A.D. 402]).
Other Witnesses
Origen
If a man departs this life with lighter faults, he is condemned to fire which burns away the lighter materials, and prepares the soul for the kingdom of God, where nothing defiled may enter. For if on the foundation of Christ you have built not only gold and silver and precious stones (I Cor., 3); but also wood and hay and stubble, what do you expect when the soul shall be separated from the body? Would you enter into heaven with your wood and hay and stubble and thus defile the kingdom of God; or on account of these hindrances would you remain without and receive no reward for your gold and silver and precious stones? Neither is this just. It remains then that you be committed to the fire which will burn the light materials; for our God to those who can comprehend heavenly things is called a cleansing fire. But this fire consumes not the creature, but what the creature has himself built, wood, and hay and stubble. It is manifest that the fire destroys the wood of our transgressions and then returns to us the reward of our great works. (Patres Groeci. XIII, col. 445, 448 [A.D. 185-232]).
Tertullian
That allegory of the Lord [Matt. 5:25-26] . . . is extremely clear and simple in its meaning . . . [beware lest as] a transgressor of your agreement, before God the judge . . . and lest this judge deliver you over to the angel who is to execute the sentence, and he commit you to the prison of hell, out of which there will be no dismissal until the smallest even of your delinquencies be paid off in the period before the resurrection. What can be a more fitting sense than this? What a truer interpretation? (The Soul 35 [A.D. 210]).
The faithful widow prays for the soul of her husband, and begs for him in the interim repose, and participation in the first resurrection, and offers prayers on the anniversary of his death (Monogamy 10 [A.D. 213]).
