It should be considered that it is safer to do to men, while one is living, the good which one hopes will be done by others after one's death. It is more blessed to depart free than to seek liberty after chains. We ought, with our whole mind, despise the present world, especially since we see it already [pg 623] passing away. We ought to immolate to God the daily sacrifice of our tears, the daily offerings of His flesh and blood. For this offering peculiarly preserves the soul from eternal death, and it renews to us in a mystery the death of the Only begotten, who, although being risen from the dead, dieth no more, and death hath no more dominion over Him (Rom. 6:9); yet, while in Himself He liveth immortal and incorruptible, for us He is immolated again in this mystery of the sacred oblation. For it is His body that is there given, His flesh that is divided for the salvation of the people, His blood that is poured, no longer into the hands of unbelievers, but into the mouths of the faithful. For this let us ever estimate what this sacrifice is for us, which for our absolution ever imitates the passion of the only begotten Son. For what one of the faithful can have any doubt that at the very hour of the offering [immolatio], at the word of the priest, the heavens are opened, the choirs of angels are present at the mystery of Jesus Christ, the lowest things are united to the highest, earthly things with heavenly, and from the invisible and the visible there is made one?

The doctrine of purgatory.
Gregory hardly adds anything to Augustine more than a clearer definition after the lines laid down by Cæsarius of Arles.
From these sayings [John 12:35; II Cor. 6:2; Eccles. 9:10] it is evident that as one left the earth so one will appear before the judgment. Yet still it is to be believed that for certain slight sins there is to be before that judgment a fire of purification, because the Truth says that, if one utters blasphemy against the Holy Ghost, his sin will be forgiven him neither in this world nor in the future [Matt. 12:31]. From this saying one is given to understand that some sins can be forgiven in this life, others in a future life.
(d) Gregory the Great, In Evangelia, II, 37, 8. (MSL, 76:1279.)
The application of the sacrifice of the mass to persons in purgatory.
Not long before our time the case is told of a certain man who, having been taken captive, was carried far away [cf. Dialog., IV, 57], and because he was held a long time in chains his wife, since she had not received him back from that captivity, believed him to be dead and every week she had the sacrifice offered for him as already dead. And as often as the sacrifice was offered by his spouse for the absolution of his soul, the chains were loosed in his captivity. For having returned a long time after, greatly astonished he told his wife that on certain days each week his chains were loosed. His wife considered the days and hours, and then knew that he was loosed when, as she remembered, the sacrifice was offered for him. From that perceive, my dearest brothers, to what extent the holy sacrifice offered by us is able to loose the bonds of the heart, if the sacrifice offered by one for another can loose the chains of the body.
