Chapter II. Absolution of Censures
WHEN a censure has been incurred, it does not cease as a rule merely by lapse of time or on the correction and amendment of the delinquent. The delinquent must obtain absolution of the censure from one who is competent to give it. In some cases, however, a censure is imposed as long as certain conditions last, and then on the termination of those conditions the censure lapses without absolution.
Any confessor in the tribunal of Penance may absolve from censures inflicted by law and not reserved to the Holy See or to the bishop. Censures, too, which are imposed ab homine but by a general precept or ordinance are in the same category, and may be absolved by any confessor unless they are reserved (Can. 2253, i).
Absolution for a reserved censure must be sought from him to whom it is reserved, or from his delegate. Similarly, absolution from a censure inflicted ab homine by a particular precept must be obtained from him who inflicted it, or from his superior, or successor in office, or from some one delegated by one of these to grant absolution (Can. 2253, ii).
If a confessor in ignorance of the reservation absolves a penitent from a censure and from sin, the absolution of the censure is valid provided that it is not a censure ab homine or a censure most specially reserved to the Holy See (Can. 2247, sec. 3).
If there is question of a censure which does not prevent the reception of the sacraments if he who is under censure is rightly disposed and has ceased to be contumacious, he can be absolved from his sins, while the censure remains unabsolved.
But if there is question of a censure which prevents the reception of the sacraments he who is under censure cannot be absolved from his sins unless he has previously been absolved from the censure.
The absolution of a censure in the sacramental forum is contained in the usual form of absolution for sins prescribed in the Ritual; in the non-sacramental forum it may be given in any way, but for the absolution of excommunication it is ordinarily advisable to use the form given in the Ritual (Can. 2250).
If absolution for a censure is given in the external forum it avails also for the internal forum; if it is given in the internal forum he who is absolved if there is no scandal can act as absolved also in the external forum; but unless the grant of absolution is proved or at least can be lawfully presumed in the external forum, the censure can be urged by the superiors of the external forum and the guilty party should obey them until absolution is obtained in the same forum (Can. 2251).
When treating of the sacrament of Penance in the chapter on reserved cases we saw that any priest has unrestricted faculties to absolve any penitent in danger of death, and that a simple confessor has very large powers in more urgent cases by Canon 2254.
