St. Paul exercised it in behalf of the incestuous Corinthian whom he had condemned to a severe penance proportioned to his guilt, “that his spirit might be saved in the day of the Lord.”(474) And having learned afterwards of the Corinthian’s fervent contrition the Apostle absolves him from the penance which he had imposed: “To him, that is such a one, this rebuke is sufficient, which is given by many. So that contrariwise you should rather pardon and comfort him, lest, perhaps, such a one be swallowed up with over-much sorrow.... And to whom you have pardoned anything, I also. For, what I have pardoned, if I have pardoned anything, for your sakes I have done it in the person of Christ.”(475) Here we have all the elements that constitute an Indulgence. First—A penance, or temporal punishment proportioned to the gravity of the offence, is imposed on the transgressor. Second—The penitent is truly contrite for his crime. Third—This determines the Apostle to remit the penalty. Fourth—The Apostle considers the relaxation of the penance ratified by Jesus Christ, in whose name it is imparted. We find the Bishops of the Church, after the Apostle, wielding this same power. No one disputes the right, which they claimed from the very first ages, of inflicting canonical penances on grievous criminals, who were subjected to long fasts, severe abstinences and other mortifications for a period extending from a few days to five or ten years and even to a lifetime, according to the gravity of the offence. These penalties were, in several instances, mitigated or cancelled by the Church, according to her discretion; for a society that can inflict a punishment can also remit it. Our Lord gave His Church power not only to bind, but also to loose. This discretionary prerogative was often exercised by the Church at the intercession of those who were condemned to martyrdom, when the penitents themselves gave strong marks of fervent sorrow, as we learn from the writings of Tertullian and Cyprian. The General Council of Nice and other Synods authorize Bishops to mitigate, or even to remit altogether, public penances, whenever, in their judgment, the penitent manifested special marks of repentance. Now, in relaxing the canonical penances, or in substituting for them a milder satisfaction, the Bishops granted what we call an Indulgence. This sentence of remission on the part of the Bishops was valid not only in the sight of the Church, but also in the sight of God. Although the Church imposes canonical penances no longer, God has never ceased to inflict temporal punishment for sin. Hence Indulgences continue to be necessary now, if not as substitute for canonical penances, at least as a mild and merciful payment of the temporal debt due to God.
