Augustine
“There is an ecclesiastical discipline, as the faithful know, when the names of the martyrs are read aloud in that place at the altar of God, where prayer is not offered for them. Prayer, however, is offered for other dead who are remembered. It is wrong to pray for a martyr, to whose prayers we ought ourselves be commended” (Sermons 159:1 [A.D. 411]).
“But by the prayers of the holy Church, and by the salvific sacrifice, and by the alms which are given for their spirits, there is no doubt that the dead are aided, that the Lord might deal more mercifully with them than their sins would deserve. The whole Church observes this practice which was handed down by the Fathers: that it prays for those who have died in the communion of the Body and Blood of Christ, when they are commemorated in their own place in the sacrifice itself; and the sacrifice is offered also in memory of them, on their behalf. If, then, works of mercy are celebrated for the sake of those who are being remembered, who would hesitate to recommend them, on whose behalf prayers to God are not offered in vain? It is not at all to be doubted that such prayers are of profit to the dead; but for such of them as lived before their death in a way that makes it possible for these things to be useful to them after death” (ibid., 172:2).
“Temporal punishments are suffered by some in this life only, by some after death, by some both here and hereafter, but all of them before that last and strictest judgment. But not all who suffer temporal punishments after death will come to eternal punishments, which are to follow after that judgment” (The City of God 21:13 [A.D. 419]).
“That there should be some fire even after this life is not incredible, and it can be inquired into and either be discovered or left hidden whether some of the faithful may be saved, some more slowly and some more quickly in the greater or lesser degree in which they loved the good things that perish, through a certain purgatorial fire” (Handbook on Faith, Hope, and Charity 18:69 [A.D. 421]).
“The time which interposes between the death of a man and the final resurrection holds souls in hidden retreats, accordingly as each is deserving of rest or of hardship, in view of what it merited when it was living in the flesh. Nor can it be denied that the souls of the dead find relief through the piety of their friends and relatives who are still alive, when the Sacrifice of the Mediator [Mass] is offered for them, or when alms are given in the Church. But these things are of profit to those who, when they were alive, merited that they might afterward be able to be helped by these things. There is a certain manner of living, neither so good that there is no need of these helps after death, nor yet so wicked that these helps are of no avail after death” (ibid., 29:109).
“The man who has cultivated that remote land [Gen 3:17] and who has gotten his bread by his very great labor is able to suffer this labor to the end of this life. After this life, however, it is not necessary that he suffer. But the man who perhaps has not cultivated the land and has allowed it to be overrun with brambles has in this life the curse of his land on all his works, and after this life he will have either purgatorial fire or eternal punishment [habebit vel ignem purgationis vel poenam aeternam].” (De Genesi contra Manich 2:20:30 [c. AD 389])
“‘Lord, rebuke me not in Your indignation, nor correct me in Your anger’ [Psalm 38:1]…In this life may You cleanse me and make me such that I have no need of the corrective fire, which is for those who are saved, but as if by fire…for it is said: ‘He shall be saved, but as if by fire’ [1 Cor 3:15]. And because it is said that he shall be saved, little is thought of that fire. Yet plainly, though we be saved by fire, that fire will be more severe than anything a man can suffer in this life.” (Explanations of the Psalms 37:3 [c. AD 392])
Cyprian of Carthage
“The strength of the truly believing remains unshaken; and with those who fear and love God with their whole heart, their integrity continues steady and strong. For to adulterers even a time of repentance is granted by us, and peace * is given. Yet virginity is not therefore deficient in the Church, nor does the glorious design of continence languish through the sins of others. The Church, crowned with so many virgins, flourishes; and chastity and modesty preserve the tenor of their glory. Nor is the vigor of continence broken down because repentance and pardon are facilitated to the adulterer. 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]).*
