On Sept. 17, Pope John Paul II did indeed stress the need to pray for the souls in purgatory. He said, "The first and highest form of charity for brothers is the ardent desire for their eternal salvation .... Christian love knows no boundaries and goes beyond the limits of space and time, enabling us to love those who have already left this earth." Therefore, not only the belief in purgatory but also the spiritual duty to pray for the souls there remains part of our Catholic Faith.

Contrary to what some may erroneously believe, Vatican II's Dogmatic Constitution on the Church asserted, "This sacred council accepts loyally the venerable faith of our ancestors in the living communion which exists between us and our brothers who are in the glory of Heaven or who are yet being purified after their death; and it proposes again the decrees of the Second Council of Nicea, of the Council of Florence, and of the Council of Trent" (no. 51).

Moreover, the Catechism clearly affirms the Church's belief in purgatory and the purification of the soul after death: "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. The Church gives the name purgatory to this final purification of the elect, which is entirely different from the punishment of the damned." (Cf. no. 1030-32).

As Vatican II stated, the Church has consistently believed in a purification of the soul after death. This belief is rooted in the Old Testament. In the Second Book of Maccabees, we read of how Judas Maccabees offered sacrifices and prayers for soldiers who had died wearing amulets, which were forbidden by the Law; Scripture reads, "Turning to supplication, they prayed that the sinful deed might be fully blotted out" (12:42) and "Thus, [Judas Maccabees] made atonement for the dead that they might be freed from the sin" (12:46). This passage gives evidence of the Jewish practice of offering prayers and sacrifices to cleanse the soul of the departed.

Rabbinic interpretation of Scripture also attests to the belief. In the Book of the Prophet Zechariah, the Lord spoke, "I will bring the one third through fire, and I will refine them as silver is refined, and I will test them as gold is tested" (13:9); the School of Rabbi Shammai interpreted this passage as a purification of the soul through God's mercy and goodness, preparing it for eternal life. In Sirach 7:33, "Withhold not your kindness from the dead" was interpreted as imploring God to cleanse the soul. In sum, the Old Testament clearly attests to some kind of purification process of the soul of the faithful after death.

The New Testament has few references about a purging of the soul or even about heaven for that matter. Rather the focus is on preaching the gospel and awaiting the second coming of Christ, which only later did the writers of sacred Scripture realize could be after their own deaths. However, in Matthew 12:32, Jesus' statement that certain sins "will not be forgiven either in this world or in the world to come," at least suggests a purging of the soul after death. Pope St. Gregory (d. 604) stated, "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." The Council of Lyons (1274) likewise affirmed this interpretation of our Lord's teaching.

The early Church preserved the belief in offering prayers for the purification of the soul. Pope St. Gregory said, "Let us not hesitate to help those who have died and to offer our prayers for them." St. Ambrose (d. 397) preached, "We have loved them during life; let us not abandon them in death, until we have conducted them by our prayers into the house of the Lord." Moreover, the Church has affirmed this belief many times, as Vatican II stated.

The key to this answer, however, is to see the beauty behind the doctrine of purgatory. We believe that God gave us a free will so that we could choose between right and wrong, good and evil. Our free will allows us to make the one fundamental choice — to love God. An act of the free will also entails responsibility. When we choose not to love God and thereby sin, we are responsible for that sin. God in His justice holds us accountable for such sins, but in His love and mercy desires us to be reconciled to Himself and our neighbor. During our life on this earth, if we really love God, we examine our consciences, admit our sins, express contrition for them, confess them, and receive absolution for them in the Sacrament of Penance. We perform penances and other sacrifices to heal the hurt caused by sin. In so doing, we are continually saying "yes" to the Lord. In a sense our soul is like a lens — when we sin, we cloud the lens; it gets dirty, and we lose the focus of God in our lives. Through confession and penance, God cleanses the "lens" of our soul. When we die, if we leave this life fundamentally loving God, dying in His grace and friendship, and free of mortal sin, we will have eternal salvation and attain the beatific vision — we will see God for who He is. If we die with venial sins or without having done sufficient penance for our sins, God in His love, mercy, and justice will purify our souls, "cleanse the lens" so to speak. After such purification, the soul will then be united with God in Heaven and enjoy the beatific vision.

Protestants have difficulty with the doctrine of Purgatory for basically two reasons: First, when Martin Luther translated the Bible into German in 1532, he removed seven books of the Old Testament, including the two Books of Maccabees, where at least implicitly the purification of the soul is found. Second, John Calvin preached that we had lost our free will due to Original Sin and that God had predetermined whether a soul was saved or damned; therefore, if we cannot choose to sin and if our eternal destiny is predetermined, who needs a Purgatory? In all, the Protestant leaders cast aside centuries of Christian Church teaching when they denied the doctrine of Purgatory.
