St. Pope Pius X: "The Most Blessed Virgin is the Mother at Once of God and Men... 'She is the Neck of Our Head, by which He Communicates... All Spiritual Gifts'"
Saint Pope Pius X showed that the Incarnation of Jesus Christ is continued in the the Mystical Body of Christ, the Church, as St. Paul teaches: "[God] made Him Head over the over all the Church, which is His body" (Eph. 1:22,23). So it follows according to St. Pius X that the Mother of God who "furnished the material of His flesh to the Only Son of God, Who was to be born with human members" who are "His body" will "transfuse His gifts into us, His members, and above all that of knowing Him and living through Him (I John iv., 9)":
If then the most Blessed Virgin is the Mother at once of God and men, who can doubt that she will work with all diligence to procure that Christ, Head of the Body of the Church (Coloss. i., 18), may transfuse His gifts into us, His members, and above all that of knowing Him and living through Him (I John iv., 9)?
Moreover it was not only the prerogative of the Most Holy Mother to have furnished the material of His flesh to the Only Son of God, Who was to be born with human members (S. Bede Ven. L. Iv. in Luc. xl.), of which material should be prepared the Victim for the salvation of men; but hers was also the office of tending and nourishing that Victim, and at the appointed time presenting Him for the sacrifice. Hence that uninterrupted community of life and labors of the Son and the Mother, so that of both might have been uttered the words of the Psalmist"My life is consumed in sorrow and my years in groans" (Ps xxx., 11). When the supreme hour of the Son came, beside the Cross of Jesus there stood Mary His Mother, not merely occupied in contemplating the cruel spectacle, but rejoicing that her Only Son was offered for the salvation of mankind, and so entirely participating in His Passion, that if it had been possible she would have gladly borne all the torments that her Son bore (S. Bonav. 1. Sent d. 48, ad Litt. dub. 4). And from this community of will and suffering between Christ and Mary she merited to become most worthily the Reparatrix of the lost world (Eadmeri Mon. De Excellentia Virg. Mariae, c. 9) and Dispensatrix of all the gifts that Our Savior purchased for us by His Death and by His Blood.
It cannot, of course, be denied that the dispensation of these treasures is the particular and peculiar right of Jesus Christ, for they are the exclusive fruit of His Death, who by His nature is the mediator between God and man. Nevertheless, by this companionship in sorrow and suffering already mentioned between the Mother and the Son, it has been allowed to the august Virgin to be the most powerful mediatrix and advocate of the whole world with her Divine Son (Pius IX. Ineffabilis). The source, then, is Jesus Christ "of whose fullness we have all received" (John i., 16), "from whom the whole body, being compacted and fitly joined together by what every joint supplieth, according to the operation in the measure of every part, maketh increase of the body unto the edifying of itself in charity" (Ephesians iv., 16). But But Mary, as St. Bernard justly remarks, is the channel (Serm. de temp on the Nativ. B. V. De Aquaeductu n. 4); or, if you will, the connecting portion the function of which is to join the body to the head and to transmit to the body the influences and volitions of the head - We mean the neck. Yes, says St. Bernardine of Sienna, "she is the neck of Our Head, by which He communicates to His mystical body all spiritual gifts" (Quadrag. de Evangel. aetern. Serm. x., a. 3, c. iii.).
We are then, it will be seen, very far from attributing to the Mother of God a productive power of grace - a power which belongs to God alone. Yet, since Mary carries it over all in holiness and union with Jesus Christ, and has been associated by Jesus Christ in the work of redemption, she merits for us de congruo, in the language of theologians, what Jesus Christ merits for us de condigno, and she is the supreme Minister of the distribution of graces. Jesus "sitteth on the right hand of the majesty on high" (Hebrews i. b.). Mary sitteth at the right hand of her Son - a refuge so secure and a help so trusty against all dangers that we have nothing to fear or to despair of under her guidance, her patronage, her protection. (Pius IX. in Bull Ineffabilis).
