O Infinite Lord, Whose mercy knows no bounds, through the merits of the Archangel Michael and in remembrance of the sorrows borne with love by the Blessed Mother when the breast of Your Son was pierced with a lance at Mt. Calvary and when her own heart was rent by the sword of man’s ingratitude, deign, I beseech You, to grant eternal glory to the suffering souls in purgatory.
Have mercy on poor sinners, O God, and extend Your mantle of protection upon me so that my prayers for the Holy Souls will be of avail. And I humbly beg You to grant my petition in this novena, if it be for Your greater glory and the salvation of souls. Amen.
