Reconciliation

There are four primary actions in the celebration of the Sacrament of Reconciliation, all of which contribute in some way to the healing that takes place: confession of sin; expression of contrition or sorrow for sin; doing penance ("satisfaction"), which expresses a desire to avoid sin; and absolution from sin. - USCCB

The Sacrament of Reconciliation, also known as Confession or Penance, is a Catholic sacrament that allows people to be absolved of sins committed after baptism and reconciled with the Christian community and God. The sacrament's purpose is to restore a person's relationship with God and heal their soul.
