III. THE FINAL PURIFICATION, OR PURGATORY
1030 All who die in God’s grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven.
[1031] The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned.606 The Church formulated her doctrine of faith on Purgatory especially at the Councils of Florence and Trent. The tradition of the Church, by reference to certain texts of Scripture, speaks of a cleansing fire:607
As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in the age to come. From this sentence we understand that certain offenses can be forgiven in this age, but certain others in the age to come.608
[1032] This teaching is also based on the practice of prayer for the dead, already mentioned in Sacred Scripture: "Therefore [Judas Maccabeus] made atonement for the dead, that they might be delivered from their sin."609 From the beginning the Church has honored the memory of the dead and offered prayers in suffrage for them, above all the Eucharistic sacrifice, so that, thus purified, they may attain the beatific vision of God.610 The Church also commends almsgiving, indulgences, and works of penance undertaken on behalf of the dead:
Let us help and commemorate them. If Job’s sons were purified by their father’s sacrifice, 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.611
In other words, Pope Leo X said Luther was wrong in contending that souls in purgatory could still earn merits for themselves in any way (including by praying) and thus make their purgatory easier or reduce their purgatory time by praying for themselves, or doing anything themselves. Your time for earning merit ends when you die. You don’t get to earn more merit after death.
- The souls in purgatory are not sure of their salvation, at least not all; nor is it proved by any arguments or by the Scriptures that they are beyond the state of meriting or of increasing in charity.

In the Bull “Exurge Domine” Leo X condemns the proposition (n. 38) “Nec probatum est ullis aut rationibus aut scripturis ipsas esse extra statum merendi aut augendae caritatis” (There is no proof from reason or Scripture that they [the souls in purgatory] cannot merit or increase in charity). For them “the night has come in which no man can labour”, and Christian tradition has always considered that only in this life can man work unto the profit of his own soul. The Doctors of the Middle Ages while agreeing that this life is the time for merit and increase of grace, still some with St. Thomas seemed to question whether or not there might be some non-essential reward which the souls in purgatory might merit (IV, dist. xxi, q. i, a. 3). Bellarmine believes that in this matter St. Thomas changed his opinion and refers to a statement of St. Thomas (“De Malo”, q. vii, a. 11). Whatever may be the mind of the Angelic Doctor, theologians agree that no merit is possible in purgatory, and if objection be urged that the soulsthere merit by their prayers, Bellarmine says that such prayers avail with God because of merit already acquired “Solum impetrant ex meritis praeteritis quomodo nunc sancti orando) pro nobis impetrant licet non merendo” (They avail only in virtue of past merits as those who are now saints intercede for us not by merit but by prayer). (loc. cit. II, cap. iii).
