If you forgive the sins of any, they are forgiven them; if you retain the sins of any, they are retained.” John 20:23

It is called the Sacrament of Conversion, of Penance, of Confession, of Forgiveness and of Reconciliation.

Those who approach the Sacrament of Penance obtain pardon from God’s mercy for the offence committed against him, and are, at the same time, reconciled with the Church which they have wounded by their sins and which by charity, by example and by prayer labours for their conversion.
