CATECHISM OF THE CATHOLIC CHURCH (CCC) ARTICLE 4 THE SACRAMENT OF PENANCE AND RECONCILIATION
1485 “On the evening of that day, the first day of the week,” Jesus showed himself to his apostles. “He breathed on them, and said to them: ‘Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained’” (Jn 20:19, 22-23). 1486 The forgiveness of sins committed after Baptism is conferred by a particular sacrament called the sacrament of conversion, confession, penance, or reconciliation. ... 1496 The spiritual effects of the sacrament of Penance are: —reconciliation with God by which the penitent recovers grace; —reconciliation with the Church; —remission of the eternal punishment incurred by mortal sins; —remission, at least in part, of temporal punishments resulting from sin; —peace and serenity of conscience, and spiritual consolation; —an increase of spiritual strength for the Christian battle.
2042 ...(“You shall confess your sins at least once a year.”) ensures preparation for the Eucharist by the reception of the sacrament of reconciliation, which continues Baptism’s work of conversion and forgiveness.
