Whether the prayers of the Church, the sacrifice of the altar and alms profit the departed?

Objections

Objection 1 : It would seem that the souls of the departed are not assisted only by the prayers of the Church, the sacrifice of the altar and alms, or that they are not assisted by them chiefly. For punishment should compensate for punishment. Now fasting is more penal than almsgiving or prayer. Therefore fasting profits more as suffrage than any of the above.
Objection 2 : Further, Gregory reckons fasting together with these three, as stated in the Decretals (xiii, Q. ii, Cap. 22): "The souls of the departed are released in four ways, either by the offerings of priests, or the alms of their friends, or the prayers of the saints, or the fasting of their kinsfolk." Therefore the three mentioned above are insufficiently reckoned by Augustine (De Cura pro Mort. xviii).
Objection 3 : Further, Baptism is the greatest of the sacraments, especially as regards its effect. Therefore Baptism and other sacraments ought to be offered for the departed equally with or more than the Sacrament of the altar.
Objection 4 : Further, this would seem to follow from the words of 1 Cor. 15:29, "If the dead rise not again at all, why are they then baptized for them?" Therefore Baptism avails as suffrage for the dead.
Objection 5 : Further, in different Masses there is the same Sacrifice of the altar. If, therefore, sacrifice, and not the Mass, be reckoned among the suffrages, it would seem that the effect would be the same whatever Mass be said for a deceased person, whether in honor of the Blessed Virgin or of the Holy Ghost, or any other. Yet this seems contrary to the ordinance of the Church which has appointed a special Mass for the dead.
Objection 6 : Further, the Damascene (Serm.: De his qui in fide dormierunt) teaches that candles and oil should be offered for the dead. Therefore not only the offering of the sacrifice of the altar, but also other offerings should be reckoned among suffrages for the dead.
