RECONCILIATION
"Those who approach the Sacrament of Penance and Reconciliation obtain pardon from God’s mercy for the offense 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 labors for their conversion" (CCC 1422).
Have mercy on me, O God,
in accord with your merciful love;
in your abundant compassion
blot out my transgressions.
Thoroughly wash away my guilt;
and from my sin cleanse me. (Psalm 51:3-4)
