The sacrament of Reconciliation is the experience within the Christian community, under the leadership of the bishop or priest, in which sinners are reconciled both to God and to the Church.
The Sacrament of Reconciliation, as Individual Confession of one Penitent, is performed in the reconciliation room or in the confessionals in the main body of a church. The Reconciliation room is designed to safeguard the penitent’s anonymity or to allow the option of an informal fact-to-face exchange between the penitent and the priest.
Bishops and priests celebrate the Sacrament of Reconciliation.
