Application of Mass

Application of the Mass.—All the faithful, especially those who are present and also the celebrant himself, benefit by the Mass, but there is a special fruit reserved to those for whose intention the Mass is offered by the priest; for the Mass is a sacrifice of intercession, propitiation, and satisfaction, and since the priest acts in the person of Christ he may apply its benefits specially to some particular person or persons. In the following cases the celebrant is bound to make this application of the ministerial fruit of the Mass.

(a) In virtue of their office, pastors are seriously obliged to say Mass for their flocks. There is a natural obligation on account of the relationship between the pastor and the people, and there is also a divine obligation, inasmuch as the priest is appointed to offer gifts and sacrifices for sin (Heb., v, 1). The details of this duty, as to the time, place and person, are prescribed in Canons 306, 339, 466. There is a grave duty of saying for the people the number of Masses which the Church orders; but the non-observance of the circumstances is not a mortal sin, unless it happens frequently and without reason.

(b) In virtue of justice, a priest who has received a stipend is bound to apply the Mass for the intention of the donor, and to observe the conditions of the agreement (i.e., the time, place, and kind of Mass specified by the donor). The duty of application is a grave one, because the loss inflicted on the donor by non-application of the Mass to his intention is serious; the duty of observance of the accidental conditions, however, is not generally grave, but it becomes grave if its neglect inflicts serious harm (e.g., if the donor makes the date of the Mass a conditio sine qua non, or if the Mass must be said at once on account of an urgent and immediate necessity). Restitution is obligatory if the Mass is not applied, or if essential conditions are not complied with; it is obligatory sub gravi, if the stipend equals what is relatively grave matter in theft.

(c) In virtue of obedience, subjects are held to apply Masses for the intention of their prelates, secular or religious, though bishops are counselled to exact this most rarely. The obligation is grave or light according to the intention of the superior, but if the application is also due in justice to the giver of the stipend, there is a serious duty.

(d) In virtue of religion or fidelity, there is an obligation of application when a priest has vowed this to God, or freely promised it to man. The duty is grave or light according to the intention of the vower or promisor (see 2210, 2407). But if there is an onerous promise (e.g., in a society of priests whose members agree to say Mass for fellow-members who have died), the duty is one of justice. One Mass satisfies several free promises, if distinct Masses were not promised.

Duties of the Priest as to the Application of Mass.—(a) For Whom May Mass Be Applied?—Mass may be offered for all objects not forbidden. From the divine law it is forbidden to offer Mass for those who are incapable of receiving its benefits (e.g., the demons, infants who died without Baptism, the Saints), or for intentions that are displeasing to God (e.g., for success in evil). From the ecclesiastical law certain restrictions are made on the application of Mass in order to safeguard reverence and prevent scandal. Thus, Mass may be said only privately (that is, without publicity or special liturgical solemnity) and prudently (that is, with avoidance of scandal, for example, by the declaration that Mass is said for the faithful departed with the purpose of aiding also a departed unbeliever, if this is pleasing to God) for the living and dead outside the Church, such as infidels, heretics, schismatics, and the excommunicated. Moreover, for a vitandus Mass may be applied only when the intention is his conversion (Canon 809).

(b) How Mass Must Be Applied.—The intention must be formed by the priest, since he represents Christ. But since his application does not produce but only bestows the fruits, it suffices that his applicatory intention be habitual and implicit, as when the celebrant has forgotten the intention formed before Mass, or applies according to the mind of his superior. The person or purpose to which Mass is applied must be at least implicitly determined, and the application must be made at least before the second consecration. If there are two conflicting intentions, the stronger prevails (2667), and, if it is doubtful which one was stronger, Mass should be next offered for the intention which God knows was not satisfied. It is unlawful to apply Mass by anticipation for the next person who will offer a stipend.
