Purgatory

[tinytherese]

If our sins are forgiven by going to confession and doing the penance given to us, then why do we still need to atone for our sins in Purgatory?

[Nihil Obstat]

Confession forgives you of your sins and restores you to a state of sanctifying grace. But even in a state of grace, we may require further purification. Nothing unclean can enter heaven, so first we would need to be perfectly cleansed from attachment to sin, and in justice we may still be due some temporal punishment for our previous sins.

 

The CCC says:

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

 

The Council of Florence said: 

"If they have died repentant for their sins and having love of God, but have not made satisfaction for things they have done or omitted by fruits worthy of penance, then their souls, after death, are cleansed by the punishment of Purgatory; also . . . the suffrages of the faithful still living are efficacious in bringing them relief from such punishment, namely the Sacrifice of the Mass, prayers and almsgiving and other works of piety which, in accordance with the designation of the Church, are customarily offered by the faithful for each other."

 

Also the Council of Trent said:

"Among them is also the fire of purgatory, in which the souls of just men are cleansed by a temporary punishment, in order to be admitted into their eternal country, into which nothing defiled entereth. The truth of this doctrine, founded, as holy Councils declare,' on Scripture, and confirmed by Apostolic tradition, demands exposition from the pastor, all the more diligent and frequent, because we live in times when men endure not sound doctrine." Catechism of Council of Trent, The Creed - Article V, Different Abodes Called Hell
"Prayers for the dead, that they may be liberated from the fire of purgatory, are derived from Apostolic teaching" Catechism of Council of Trent, Prayer
"We also beg of God that we be not cut off by a sudden death; that we provoke not His anger against us; that we be not condemned to suffer the punishments reserved for the wicked; that we be not sentenced to endure the fire of purgatory, from which we piously and devoutly implore that others may be liberated." Catechism of Council of Trent, The Lord's Prayer, Seventh Petition

If our sins are forgiven by going to confession and doing the penance given to us, then why do we still need to atone for our sins in Purgatory?

​because sin contains guilt and effect. Forgiveness removes the sin, Purgatory purifies and removes the effect of sin.
