Prayer for the Holy Souls | Novena Day 6

The holy souls are, indeed, comforted by the recollection of the passion of Jesus Christ, and the Holy Sacrament of the Altar, since they know they are saved by the passion of Jesus Christ, and have received, and still receive, so much consolation from Holy Masses and Holy Communions. Nevertheless, they are greatly pained by the recollection of their ingratitude for these two gifts of love of Jesus Christ.

Prayer: O my Divine Redeemer, Thou didst die for me on the Cross, and have so often united Thyself with me in Holy Communion, and I have repaid Thee only with ingratitude. Now, however, I love Thee above all things, O supreme God; and I am more grieved at my offenses against Thee than any other evil. I would rather die than offend you again. Grant me the grace of holy perseverance. Have compassion on me, and at the same time, on the holy souls in purgatory.

O Mary, Mother of God, come to their assistance with thy powerful intercession.

Our Father...
Hail Mary...
O most sweet Jesus, have mercy on them!
On Thy spouses have compassion,
on these suffering children Thine;
make these holy souls partakers
of Thy happiness Divine.
