An Invocation of the Most Holy Trinity for the Souls in Purgatory
O God of all goodness, Father of mercies, Who, at the prayers and fastings of Thy faithful people, didst vouchsafe to send Thy angels to break asunder the fetters of Thy holy apostle Peter, and to open the doors of his prison; hear even also on this day the prayers and supplications of Thy Church, and send Thy angel to the souls for whom we pray, that, the doors of their prison being opened wide, they may be happily received into the bosom of Thy mercy.
Our Father, Hail Mary, Glory be to the Father, etc., etc.
O Son of God, Saviour of souls, Who didst refresh the three children in the burning fiery furnace, pour down upon the souls that cry to Thee from the flames, Thy heavenly dew. Thy precious blood alone can quench the flames of purgatory; oh, let it now flow down upon these suffering souls, and do Thou, O Lord, have mercy upon them.
Our Father, Hail Mary, Glory be to the Father, etc., etc.
O Spirit of love, have compassion on the cruel torment which these souls endure, that are filled with the purest charity, and, aspiring without ceasing towards their God, cry aloud in their distress, “I thirst: I thirst after my God!” and yet cannot attain unto the object of their love, nor receive the least drop of that torrent of pure delights. O Holy Spirit, grant that, having felt the fiercest pangs of love, they may taste its heavenly delights in a blessed eternity. Amen.
Our Father, Hail Mary, Glory be to the Father, etc., etc.

Grant, O Lord, we beseech Thee, that while we lament the departure of Thy servant, we may always remember that we are most certainly to follow him [her]. Give us grace to prepare for that last hour by a good and holy life, that we may not be taken unprepared by sudden death, but may be ever on the watch, that, when Thou shalt call, we may go forth to meet the Bridegroom, and enter with Him into glory everlasting. Through the same Jesus Christ Our Lord. Amen.
O most wise and merciful Lord, Who hast ordained this life as a passage to the future, confining our repentance to the time of our pilgrimage here, and reserving for hereafter the state of punishment and reward; vouchsafe to us who are yet alive, and have still the opportunity of reconciliation with Thee, the grace so to watch over all our actions, and to correct every slightest wandering from the true way to heaven, that we may not be surprised with our sins uncancelled or our duties unfulfilled; but when our bodies shall go down into the grave, our souls may ascend to Thee, and dwell with Thee forever in the mansions of eternal bliss. Through Jesus Christ Our Lord and only Saviour. Amen.
