Sacrament of Penance and Reconciliation (commonly called Confession, Reconciliation or Penance) – one of seven sacraments of the Catholic Church and sacred mysteries of the Orthodoxy, in which its faithful obtain Divine mercy for the sins committed against God and neighbour and are reconciled with the community of the Church (Cf. Vatican II, Lumen Gentium 11 §2; CCC 1422). By this sacrament Christians are freed from sins committed after the Baptism. It has very complex character, since personal penitence meets here with an ecclesiastical authority. Especially since the Reformation there has been long-running disagreement between Catholic Church and Protestant denominations over this sacrament, including Church authority to absolve sins.
