He died in body through a love greater than anyone had known. She died in spirit through a love unlike any other since his. -St. Bernard of Clairvaux
Sin may seem exciting, but the truth is, it’s dull. It dulls the faculties God gifted us with when He created us. The more we sin, the more numb we become to its effects on our intellect, our will, and our senses. Because Our Lady was free from sin, even from the stain of original sin, her capacity to feel emotion was so much keener than ours. Her capacity to love, to feel joy and to feel sorrow and compassion were far beyond what we experience.
Our Lady’s martyrdom is foretold by Simeon, as Luke tells us:
And Simeon blessed them, and said to Mary his mother: Behold this child is set for the fall, and for the resurrection of many in Israel, and for a sign which shall be contradicted; And thy own soul a sword shall pierce, that, out of many hearts, thoughts may be revealed. (Lk 2:34-35)
Her martyrdom reached its apex on Calvary, as she watched her Divine Son suffer and die upon the Cross for sinful mankind, and then finally, the sword prophesied by Simeon pierced her soul.
Truly, O blessed Mother, a sword has pierced your heart. For only by passing through your heart could the sword enter the flesh of your Son. Indeed, after your Jesus—who belongs to everyone, but is especially yours—gave up his life, the cruel spear, which was not withheld from his lifeless body, tore open his side. Clearly it did not touch his soul and could not harm him, but it did pierce your heart. For surely his soul was no longer there, but yours could not be torn away. Thus the violence of sorrow has cut through your heart, and we rightly call you more than martyr, since the effect of compassion in you has gone beyond the endurance of physical suffering. -St. Bernard of Clairvaux
Because of her special role in revealing the thoughts of men’s hearts by her suffering, Fr. Chad Ripperger, an exorcist who speaks often about spiritual warfare, says that Our Lady of Sorrows can help us especially when we are trying to uncover the root cause of our sins but seem to blocked. When there is something holding us back from entering into a deeper relationship with God, we can ask Our Lady of Sorrows to intercede and show us what we’re missing. For more on this, you can listen to his talk on Our Lady of Sorrows (he speaks about how she can help reveal hidden knowledge of ourselves at about 9:28 into the talk).
O God, who didst will that in the passion of thy Son a sword of grief should pierce the soul of the blessed Virgin Mary his Mother: Mercifully grant that thy Church, having shared with her in his passion, may be made worthy to share in the joys of his resurrection; through the same thy Son Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever. Amen.
