All Souls Day

The practice of recommending to God the souls of the departed in that we may mitigate the great pains which they suffer, and that He may soon bring them to His glory, is most pleasing to God and most profitable to us. For those blessed souls are His eternal spouses, and they are most grateful to those who obtain their deliverance from prison, or even a mitigation of their torments.

Hence, when they shall enter into heaven, they will certainly not forget those who prayed for them. It is a pious belief that God manifests to them our prayers for them, that they also may pray for us.

Let us recommend to Jesus Christ, and to His holy Mother, all the souls in Purgatory, but especially those of our relatives, benefactors, friends, and enemies, and, still more particularly, the souls of those for whom we are bound to pray; and let us consider the great pains which these holy spouses of Jesus Christ endure, and offer to God for their relief the Masses of this day.
