Third Precept: Yearly Confession
The Third Precept of the Church
The Third Precept of the Church.—This precept commands that all the faithful, male and female, who have reached the age of discretion go to confession at least once a year (Canon 906).
(a) The subject of this precept is every baptized person who has entered the Church through valid Baptism and who has the use of reason, which begins usually at the age of seven. Infants are incapable of committing sin, and the unbaptized are incapable of receiving the Sacrament of Penance.
(b) The matter of the precept is a good sacramental confession of the grave sins not yet confessed, made with the purpose of obtaining absolution to any duly authorized priest. Hence, those who have only venial sins on their conscience are not bound according to the common opinion by this precept, and, on the other hand, those who make a sacrilegious or voluntarily null confession do not fulfill the law (Denzinger, n. 1114; Code, Canon 907). It seems that one who, after a confession of venial sins at Easter, falls into grave sin is not bound from this precept to confess again before the end of the year.
(c) The time for fulfillment of the precept is once during the year. The law leaves one free to confess on any day during the twelvemonth, and to count the year either civilly (i.e., from January 1 to December 31), or ecclesiastically (e.g., from Easter time to Easter time, as is commonly done), or from the date of the last confession. The limit is set, however, not to terminate but to insist upon obligation, and hence it seems that he who has not made his 1957 confession must make it as soon as possible in 1958, but the 1957 confession made in 1958 will satisfy for the 1958 obligation also (see 468 sqq.).
The Obligation of the Third Precept
The Obligation of the Third Precept.—(a) Origin.—From divine law sacramental confession is necessary for all who have fallen into serious sin after Baptism, since Christ has given His Church the keys of heaven and appointed His bishops and priests the physicians and judges to cure and pardon (Matt., xviii. 18; John, xx. 23). But Our Lord did not fix the frequency of confession, and it is this which the present precept determines. The law of annual confession goes back to the Fourth Lateran Council (1215).
(b) Gravity.—The precept of annual confession obliges under pain of mortal sin, for its purpose is of vital importance and the Church has always regarded it as a grave obligation. The purpose of the law is to ensure the use of the Sacrament instituted by Christ for forgiveness and to keep sinners from delaying their repentance too long. If a good business man takes stock of his assets and liabilities at least once a year, and those who are careful of their health have medical attention or examination at least yearly, it is most reasonable that the faithful should settle their spiritual accounts and attend to the well-being of their souls within an equal period of time. In the early centuries when fervor was greater and conditions different, no general church law on the frequency of confession was needed; but there is no doubt that the Lateran Decree met well the need that began after the change from the early penitential discipline, The penalties for violation of this precept were excommunication and exclusion from ecclesiastical burial, and, though they are not enforced today, they show the intention of the Church to impose a grave duty.
