The sacrament of Reconciliation is one of two sacraments of healing. It is the sacrament that brings spiritual healing for Catholics who have distanced themselves from God by committing sins. There are four elements involved: 1) the penitent’s contrition for sin; 2) confession to a priest; 3) absolution by the priest; and 4) satisfaction.
Through penance, we receive pardon through God's mercy for sins committed. At the same time, we are reconciled with the Church community. The confession, or disclosure, of sins frees us and facilitates our reconciliation with others.
