On this memorial of The Immaculate Heart of Mary, we remember Mary as having the perfect human heart, untouched by sin. In iconography, Mary's Immaculate Heart is pictured in flames, recalling the burning bush that Moses encountered on Mount Horeb from which God spoke of his desire to save humanity. Mary's heart was grafted on to God's heart when she said agreed to become the Mother of God. Even though we see in the Gospel that Mary did not always understand the plan of God, her burning love never wavered.
