There is a deep connection between Mary’s Immaculate Heart and the Holy Sacrifice of the Mass. Our Lady pondered and preserved in her heart all the wondrous events of her Son – especially His Passion (cf. Lk 2:19, 51). As a very real mother, Our Lady took note of the slightest details regarding her Son. Her heart is a sacred depository of God. Now Holy Mass makes all these mysteries – contained in her Immaculate Heart – present for us! We are meant to ponder and preserve the Passion, marvelous mysteries, and events of Christ’s life. Imitate Mary thus and you will grow in great sanctity.
