Does purgatory really exist?

Whether there is a Purgatory after this life? Objection 1. It would seem that there is not a Purgatory after this life. For it is said (Apocalypse 14:13): "Blessed are the dead who die in the Lord. From henceforth now, saith the Spirit, that they may rest from their labors." Therefore after this life no cleansing labor awaits those who die in the Lord, nor those who do not die in the Lord, since they cannot be cleansed. Therefore there is no Purgatory after this life. Reply to Objection 1. The authority quoted is speaking of the labor of working for merit, and not of the labor of suffering to be cleansed. It is said (2 Maccabees 12:46): "It is a holy and wholesome thought to pray for the dead, that they may be loosed from sins." Now there is no need to pray for the dead who are in heaven, for they are in no need; nor again for those who are in hell, because they cannot be loosed from sins. Therefore after this life, there are some not yet loosed from sins, who can be loosed therefrom; and the like have charity, without which sins cannot be loosed, for "charity covereth all sins" [Proverbs 10:12]. Hence they will not be consigned to everlasting death, since "he that liveth and believeth in Me, shall not die for ever" [John 11:26]: nor will they obtain glory without being cleansed, because nothing unclean shall obtain it, as stated in the last chapter of the Apocalypse (verse 14). Therefore some kind of cleansing remains after this life. ST. Appendix 2. A 1.
