The Virginal Heart of the Blessed Mother of Jesus has more love for her Dear Son than all the angels and saints together; thus the Sacred Heart of the Only Son of Mary is so full of love for His most loving Mother that He is more to her than all created things together.

Let us offer to Jesus the Heart and love of His Blessed Mother in reparation for all our want of love and service towards Him. Let us offer to His most worthy Mother, who is also our Mother, the Heart and love of her Son in satisfaction for our ingratitude and infidelity towards her.

Not only is the Blessed Virgin the first object, after God, of the ardent love of the Sacred Heart of Jesus, but the Sacred Heart is really the Heart of Mary for five principal reasons.

The first three reasons are: 1. because the Eternal Father has given her the Heart of His Only-begotten Son as a father gives the heart of a son to his mother; 2. because the Son has given His most loving Heart to the most admirable of mothers; 3. because the Holy Spirit has given Mary the very spirit of love which unites the Blessed Trinity in the Sacred Heart of her Son. These Three Divine Persons continually and eternally give Mary the adorable Heart of the God-Man, so that she may give us her most precious gift, the Sacred Heart of her Divine Son.

Incessant and everlasting praise be to the Father, to the Son, and to the Holy Spirit for this infinitely precious gift that They have given to our Blessed Mother and through her to us. O Most Holy Trinity, I offer Thee the most adorable Heart of Jesus and the most loving Heart of His Mother in thanksgiving for Thy infinite goodness in my regard. I also offer Thee, in union with those two most amiable Hearts, my own unworthy heart, with the hearts of all my brethren, humbly beseeching Thee to take full possession of them forever.

The fourth reason why the Sacred Heart is truly the Heart of Mary is that the Eternal Father, having considered the Blessed Virgin from the very instant of her conception as the one chosen to be the Mother of God, gave her from the first moment of her life a love similar to His love for His Divine Son. According to many theologians, Mary had more love for Jesus at that moment than all the Seraphim will ever have. Therefore, Mary’s incomparable love for Jesus drew Him into her sacred womb and into her Heart to rest there eternally as the Heart of her Heart and as a Divine Sun that sheds its celestial light into her soul and inflames it with divine fire.

The fifth reason why the Sacred Heart of Jesus is the heart of Mary is that, at the moment of the Incarnation, she cooperated with the Blessed Trinity to form the human Heart of Jesus, which was formed of her virginal blood. The blood of her holy Heart passed into the Heart of Jesus and received the perfection that was needed to form the Heart of the God-Man. This divinely human and humanly divine Heart dwelt in the sacred womb of Mary as a furnace of divine love, a furnace which transformed the Heart of Mary into the Heart of Jesus and made these two Hearts but one and the same Heart in a unity of spirit, affection and will.

The holy Heart of Mary was, therefore, always closely united to the Sacred Heart of her Divine Son. She always willed what He willed and also consented to act and to suffer so that the work of our salvation might be accomplished. Hence, the Fathers of the Church plainly assert that the Mother of the Savior cooperated with Him in a very special way in the redemption of mankind. That is why our holy Redeemer told St. Bridget of Sweden, whose revelations have been approved by the Church, that He and His holy Mother worked in perfect harmony, uno corde, for our salvation.

Thus the Sacred Heart of Jesus is the Heart of Mary. These two Hearts are but one Heart, which was given to us by the Blessed Trinity and by our Blessed Mother, so that we, the children of Jesus and Mary, might have but one Heart with our Heavenly Father and our holy Mother and that we might love and glorify God with the same Heart, a Heart worthy of the infinite grandeur of His divine majesty.
