Marian Coredemption and Mediation: An Introduction

Updated: May 30, 2020

In the course of two millennia and under the guidance of the Holy Spirit the Catholic Church has come to an ever more focused understanding of the person and role of the Blessed Virgin Mary, the Mother of God. The first Marian dogma stating that Mary is in fact the Theotókos, the God-bearer or Mother of God was solemnly declared by the Fathers of the Council of Ephesus in 431.1

Subsequently at the Lateran Council of 649 convoked by Pope St. Martin I the Church reached the certitude that Mary is ever Virgin: that she was a virgin before, during and after giving birth to Jesus.2 After centuries of debate the Catholic Church arrived at the assurance that Mary was immaculate from the first moment of her conception. 3 Finally in 1950, after ascertaining the Church’s long held belief, the Venerable Pius XII formally defined that the Virgin Mary was taken up body and soul into the glory of heaven.4 Each of these truths are mysteries of faith which means that they are so deep our human minds can never fully exhaust their richness.

All four of these dogmas refer to the person of Mary in relation to her Son, the God-man, Jesus Christ. But, in fact, Catholics believe even more about Mary than these profound mysteries regarding her person. They also believe that she played and continues to play an entirely unique role in the work of our salvation. In the course of the second millennium saints and theologians have been meditating, preaching and writing about Mary’s collaboration in the work of redemption and in the distribution of grace while for over one hundred fifty years the Popes have teaching about her maternal role.

I. The Mystery of Marian Coredemption

It is precisely this role or function that I would like to present today and I believe that there is no better place to begin than with the teaching of the Second Vatican Council, which devoted more space to the Mother of God than any other Ecumenical Council of the Church. Thus the Dogmatic Constitution on the Church Lumen Gentium speaks of Mary as “under and with him [Christ], serving the mystery of redemption, by the grace of Almighty God” [sub Ipso et cum Ipso, omnipotentis Dei gratia, mysterio remdeptionis inserviens], as “freely cooperating in the work of man’s salvation” [humanæ saluti cooperantem] (#56), of the “union of the mother with the Son in the work of salvation” [ cum Filio in opere salutari coniunctio] (#57) and of how she faithfully persevered in her union with her Son unto the cross, where she stood, in keeping with the divine plan [non sine divino consilio], enduring with her only begotten Son the intensity of his suffering, associated herself with his sacrifice in her mother’s heart, and lovingly consenting to the immolation of this victim which was born of her [ vehementer cum Unigenito suo condoluit et sacrificio Eius se materno animo sociavit, victimæ de se genitæ immolationi amanter consentiens] (#58).

Likewise the Council Fathers state that Mary shared her Son’s sufferings as he died on the cross. Thus, in a wholly singular way she cooperated by her obedience, faith, hope and burning charity in the work of the Savior in restoring supernatural life to souls [Filioque suo in cruce morienti compatiens, operi Salvatoris singulari prorsus modo cooperata est, oboedientia, fide, spe et flagrante caritate, ad vitam animarum supernaturalem restaurandam] (#61).

The twentieth century Popes had already clearly taught the doctrine upon which the Council Fathers could base themselves. In his great Marian Encyclical Ad Diem Illum of 2 February 1904, Saint Pius X stated:

It was not only the glory of the Mother of God to have presented to God the Only-Begotten who was to be born of human members the material by which he was prepared as a Victim for the salvation of mankind, but hers also the office of tending and nourishing that Victim, and at the appointed time of offering Him at the altar.

Hence the ever united life and labors of the Son and the Mother which permit the application to both of the words of the Psalmist: “
