The place or condition in which the souls of the just are purified after death and before they can enter heaven. They may be purified of the guilt of their venial sins, as in this life, by an act of contrition deriving from charity and performed with the help of grace. This sorrow does not, however, affect the punishment for sins, because in the next world there is no longer any possibility of merit. The souls are certainly purified by atoning for the temporal punishments due to sin by their willing acceptance of suffering imposed by God. The sufferings in purgatory are not the same for all, but proportioned to each person's degree of sinfulness. Moreover, these sufferings can be lessened in duration and intensity through the prayers and good works of the faithful on earth. Nor are the pains incompatible with great peace and joy, since the poor souls deeply love God and are sure they will reach heaven. As members of the Church Suffering, the souls in purgatory can intercede for the persons on earth, who are therefore encouraged to invoke their aid. Purgatory will not continue after the general judgment, but its duration for any particular souls continues until it is free from all guilt and punishment. Immediately on purification the soul is assumed into heaven. (Etym. Latin purgatio, cleansing, purifying.)
1 Cor. 3:15 does not teach purgatory as a place we go to in order to have some of our sins cleansed from us. It teaches that even though the person is justified by faith and cannot face damnation, his works will, however, be judged on “that day.” Those works which are good will survive the fires of judgment the way gold, silver, and precious stones can survive fire. But false works will be consumed the way fire consumes wood, hay, and straw. What is left has no bearing on whether or not we are saved. It has to do with rewards in heaven.
Purgatory is a dangerous doctrine that makes the Cross of Christ insufficient by requiring the person to undergo suffering in order to be made worthy of being with God. This is a false teaching and is to be avoided. We are justified by faith (Rom. 5:1), not by faith and works (Rom. 3:28).
There is no purgatory...sins are either or not forgiven this side of life...after death there remains no choice as the decission for or against Christ is made this side of heaven. Christ’s blood operates this side...”Once”...there is no partial cleansing after death.
