Whether suffrages offered for several are of as much value to each one as if they had been offered for each in particular?

Objections

Objection 1 : It would seem that suffrages offered for several are of as much value to each one as if they had been offered for each in particular. For it is clear that if one person receives a lesson he loses nothing if others receive the lesson with him. Therefore in like manner a person for whom a suffrage is offered loses nothing if some one else is reckoned together with him: and consequently if it be offered for several, it is of as much value to each one as if it were offered for each in particular.
Objection 2 : Further, it is to be observed that according to the common practice of the Church, when Mass is said for one deceased person, other prayers are added for other deceased persons. Now this would not be done, if the dead person for whom the Mass is said were to lose something thereby. Therefore the same conclusion follows as above.
Objection 3 : Further, suffrages, especially of prayers, rely on the Divine power. But with God, just as it makes no difference whether He helps by means of many or by means of a few, so it differs not whether He assists many or a few. Therefore if the one same prayer be said for many, each one of them will receive as much assistance as one person would if that same prayer were said for him alone.
