Many apparitions have been reported about souls in Purgatory who came to ask the offering of Padre Pio’s Holy Mass for their deliverance from Purgatory. One day he celebrated Holy Mass for the father of one of his fellow friars. At the end of the Holy Sacrifice, Padre Pio said to the friar, "This morning the soul of your father entered Heaven." The friar was very happy, but said, "Padre, my good father died thirty-two years ago." "My son," Padre Pio replied, "before God every debt must be paid!" And it is Holy Mass which obtains for us a treasure of infinite value: the Body and Blood of Jesus, the "unspotted Lamb" (Rev. 5:12).
