The Immaculate Heart:
The symbol of the Immaculate Heart , sometimes with a sword piercing it, is in reference to Simeon's prophecy in St. Luke, Chapter 32, Verse 35:
And thine own soul a sword shall pierce, that out of many hearts, thoughts may be revealed.
Other times the Lily replaces the Sword, as it does here.
The Sword is for sorrow, the Lily for purity and joy. Long ago, a circle of thorns used to replace the roses.
Remember, O Most Loving Virgin Mary, that never was it known that anyone who fled to your protection, implored your help,or sought your intercession was left unaided. Inspired with this confidence, we turn to you, o Virgin of virgins, Our Mother. To you we come, before you we stand, sinful and sorrowful. O Mother of the World Incarnate, do not despise our petitions, but in your mercy hear us and answer us. Amen. (Our Lady of Rosary feast 7th october)
"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." Luke 2:35
