Christmas Prayers for the Poor Souls in Purgatory

The above image of Holy Mass is of a Tridentine Catholic Mass for Christmas Mass at Midnight.

As Catholics, we know that Purgatory exists. Those in purgatory, however, may be helped by our prayers. I don't want to explain the whole doctrine now though, so please see the link for more information. As Scripture states, "It is a holy and wholesome thought to pray for the dead that they may be loosed from their sins" (2 Mac 12:46)

Christmas is a special time for us to in particular remember the Poor Souls. May the Infant King have mercy on them and free them from their punishment and admit them into Heaven with him. To this end, I ask that everyone pray the following prayers for the relief of the Poor Souls this Christmas:

(5) Apostle's Creed
(1) Hail Holy Queen
(1) Our Father
(1) Glory Be
(1) Requiem Aeternam

In an approved apparition by the Church, Our Savior, Jesus Christ, gave St. Gertrude the Great this prayer which we should add to our daily prayers throughout the entire year:

Eternal Father, I offer Thee the Most Precious Blood of Thy Divine Son, Jesus Christ, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, for sinners in the Universal Church, for those in my own home and within my family. Amen.
