Mary’s pure Heart is truly a heaven of which the sky over our heads is a mere shadow and image. It is a heaven exalted above all others, of which the Holy Spirit speaks when He says that the Savior of the World went out from a heaven surpassing all others in excellence, when He came on earth to redeem mankind: A summo caelo egressio ejus (Ps 18:7). As Our Admirable Mother had formed her Divine Son in her Heart before conceiving Him in her womb, we can truly say that, having remained hidden in her Heart for a little while even as He had been in the Heart of His Heavenly Father from all eternity, Our Blessed Savior emerged from it to manifest Himself to men. But just as He went forth from heaven and His Father’s bosom, without however relinquishing them: Excessit, non recessit, (1) so also is His Mother’s Heart a heaven whence He came forth in such a manner that He nevertheless remained and will remain forever in it: “For ever, O Lord, thy word standeth firm in heaven” (Ps. 118:89).
The heavens are called the special work of God’s hands: “The heavens are the works of thy hands,” (Ps. 101:26) but the Heart of the Mother of God is the unequalled masterpiece of His omnipotence, His unfathomable wisdom and His infinite goodness.
God made heaven to be the particular abode of His Divine Majesty: “The Lord hath prepared his throne in heaven” (Ps. 102:19). It is true that He fills both heaven and earth with His divinity: “I fill heaven and earth,” (Jer. 23:24) but heaven to a far greater degree than earth, for He has established there the fullness of His grandeur, power and divine magnificence: “Thy magnificence is elevated above the heavens” (Ps. 8:2). In like manner, we can truly say of the Heart of the Blessed Mother of God that it is a real Heaven of the Divinity, of the divine attributes and of the Most Blessed Trinity.
The Admirable Heart of Mary is an empyrean heaven, that is, a Heaven all fire and flames, ever burning with the fire and flames of celestial love, holier and more ardent than the love of the Seraphim and of the greatest Saints who dwell in the empyrean heaven.
Mary’s pure Heart is the Heaven of Heavens, created for God alone, because it is the priceless inheritance and rich portion of the Lord, who always possessed it most entirely: “The heaven of heaven is the Lord’s” (Ps. 113:16). Yes, the most holy Heart of the Queen of Angels is the Heaven of Heavens for three significant reasons.
First of all, Jesus Christ is truly the Heaven of the Blessed Trinity. The Holy Spirit assures us that the fullness of the Divinity abides in Him: “For in him dwells all the fullness of the Godhead,” (Col. 2:9) and this same Jesus has forever fixed His dwelling in the Blessed Heart of His most worthy Mother. This must not surprise us, for Sacred Scripture reveals that even in this present life, He maintains His dwelling in the hearts of all who believe in Him with a firm and perfect faith. We can therefore conclude that, as our most lovable Savior is Himself a Heaven, possessing no abode more glorious and delightful, next to the adorable bosom of His Eternal Father, than the Heart of His holy Mother, which is itself a Heaven, He is truly Heaven dwelling within a heaven. In this way, the Heart of the Mother of Jesus can be said to be the Heaven of Heaven.
Secondly, Mary’s Immaculate Heart is the Heaven of Heaven because the spotless Virgin is really a heaven considered in her own person. This is the quality ascribed to her by the Holy Spirit, according to a learned and holy writer: “From heaven the Lord hath looked upon the earth” (Ps. 101:20). As this commentator explains it, “the Lord, dwelling in the Blessed Virgin Mary, as in a heaven, has turned the eyes of His mercy towards the earth, that is, towards sinners.” (2) Then the same author goes on to say that this marvelous Virgin is a heaven because, as all living things in the order of nature receive their life from the influence of heaven, so does our Holy Church teach us that the life of grace is given to us through the Blessed Virgin Mary: “Vitam datam per Virginem.” (3) Now if this incomparable Virgin is a Heaven, our own heaven in this world of grace, because next to God the source of our spiritual life, we can well say that her Heart is the Heaven of Heaven, having been the principle of her corporal and spiritual life on earth and of the eternal life that she now enjoys in Heaven.
