VI. The Sacrament of Penance and Reconciliation

From The Catechism of the Catholic Church

1448
Beneath the changes in discipline and celebration that this sacrament has
undergone over the centuries, the same fundamental structure is to be
discerned. It comprises two equally essential elements: on the one hand, the
acts of the man who undergoes conversion through the action of the Holy Spirit:
namely, contrition, confession, and satisfaction; on the other, God’s action
through the intervention of the Church. the Church, who through the bishop and
his priests forgives sins in the name of Jesus Christ and determines the manner
of satisfaction, also prays for the sinner and does penance with him. Thus the
sinner is healed and re-established in ecclesial communion.
