In the sacrament of penance the faithful who confess their sins to a legitimate minister, are sorry for them, and intend to reform themselves obtain from God through the absolution imparted by the same minister forgiveness for the sins they have committed after baptism and, at the same, time are reconciled with the Church Which they have wounded by sinning.
Code of Canon Law
To speak of reconciliation and penance is for the men and women of our time an invitation to rediscover, translated into their own way of speaking, the very words with which our savior and teacher Jesus Christ began his preaching: "Repent, and believe in the Gospel"
St. John Paul II - Reconciliation and Penance
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness
1 John 1: 9
Why do we have to confess our sins to a priest? Can’t we just pray to God for forgiveness? If I sin but no one is affected then can I say, “no harm, no foul?” The Sacrament of Penance (aka Reconciliation) is one of the healing sacraments, and celebrates the loving embrace of God when we turn toward him and away from our sins.
The Sacrament of Penance and Reconciliation
Why did Christ give us the sacraments of Penance and the Anointment of the Sick?
Christ’s love is shown in the fact that he seeks the lost and heals the sick. That is why he gave us the sacraments of healing and restoration, in which we are freed from sin and strengthened in our physical and spiritual weakness.
What names are there for the sacrament of Penance?
The sacrament of Penance is also called the Sacrament of Reconciliation, of forgiveness, of conversion, or of confession.
Who instituted the sacrament of Penance?
Jesus himself instituted the sacrament of Penance when he showed himself to his apostles on Easter day and commanded them, “Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.”
Nowhere did Jesus express more beautifully what happens in the sacrament of Penance than in the parable of the Prodigal Son: We go astray, we are lost and can no longer cope. Yet our Father waits for us with great, indeed, infinite longing; he forgives us when we come back; he takes us in again, forgives our sins. Jesus himself forgave the sins of many individuals; it was more important to him than working miracles. He regarded this as the great sign of the dawning of the kingdom of God; in which all wounds are healed all tears are wiped away. Jesus forgave sins in the power of the Holy Spirit, and he handed that power on to his apostles. We fall into the arms of our heavenly Father when we go to a priest and confess.
What is penance?
Penance is making restitution or satisfaction for a wrong that has been committed. Penance must take place exclusively in my head; I must express it in acts of charity and in solidarity with others. One does penance also by praying, fasting, and supporting the poor spiritually and materially.
Penance is often misunderstood. It has nothing to do with low self-esteem or scrupulosity. Penance is not brooding over what a bad person I am. Penance frees and encourages us to make a new start.
