Question:
Answer:
In a nutshell, our belief in indulgences is rooted in the fact that we are sinners in need of God’s mercy. We all sin and will incur punishment for our sins, either in the form of eternal punishment or temporal punishment (Isa. 1:18, Rom. 5:9, 2 Sam. 12).
When we are absolved of our mortal sins in the sacrament of reconciliation, the eternal punishment is removed, but the temporal punishment remains. The Catechism explains: “Absolution takes away sin, but it does not remedy all the disorders sin has caused” (1459). Thus, the priest imposes a penance on the penitent, which can take the form of “prayer, an offering, works of mercy, service of neighbor, voluntary self-denial, sacrifices, and above all the patient acceptance of the cross we must bear” (1460).
Catechism on indulgences:
To understand this doctrine and practice of the Church, it is necessary to understand that sin has a double consequence. Grave sin deprives us of communion with God and therefore makes us incapable of eternal life, the privation of which is called the “eternal punishment” of sin. On the other hand, every sin, even venial, entails an unhealthy attachment to creatures, which must be purified either here on earth, or after death in the state called purgatory. This purification frees one from what is called the “temporal punishment” of sin. These two punishments must not be conceived of as a kind of vengeance inflicted by God from without but as following from the very nature of sin. A conversion which proceeds from a fervent charity can attain the complete purification of the sinner in such a way that no punishment would remain.
The forgiveness of sin and restoration of communion with God entail the remission of the eternal punishment of sin, but temporal punishment of sin remains. While patiently bearing sufferings and trials of all kinds and, when the day comes, serenely facing death, the Christian must strive to accept this temporal punishment of sin as a grace. He should strive by works of mercy and charity, as well as by prayer and the various practices of penance, to put off completely the “old man” and to put on the “new man” (1472-1473).
