Writer,
Even if, on occasion, he has used the term, though, I am not sure what it actually demonstrates.
I thought he was pretty clear about what he meant, that is, her cooperation in the redemptive act of Christ throughout her life, and even after her death.
From Pope John Paul II’s homily at a Marian sanctuary in Guayaquil, Ecuador, on January 31, 1985:
Mary goes before us and accompanies us. The silent journey that
begins with her Immaculate Conception and passes through the “yes” of Nazareth, which makes her the Mother of God, finds
on Calvary a particularly important moment. There also,
accepting and assisting at the sacrifice of her son, Mary is the dawn of Redemption; . . .
Crucified spiritually with her crucified son (cf. Gal. 2:20), she contemplated with heroic love the death of her God, she “
lovingly consented to the immolation of this Victim which she herself had brought forth” (Lumen Gentium, 58) . . . .
In fact, at Calvary she
united herself with the sacrifice of her Son that led to the foundation of the Church; her maternal heart shared to the very depths the will of Christ “to gather into one all the dispersed children of God” (Jn. 11:52). Having suffered for the Church, Mary deserved to become the Mother of all the disciples of her Son, the Mother of their unity . . . .
The Gospels do not tell us of an appearance of the risen Christ to Mary. Nevertheless, as she was in a special way close to the Cross of her Son, she also had to have a privileged experience of his Resurrection. In fact,
Mary’s role as Coredemptrix did not cease with the glorification of her Son.
The Pope’s homily seems to assert the common Catholic teaching on Mary as Mediatrix, which includes her role in the redemption.
Fr. John Hardon’s explanation from his
Pocket Catholic Dictionary is probably the most succinct explanation of this doctrine that I have found.
MEDIATRIX**.** A title of the Blessed Virgin as mediator of grace. There are two aspects of this mediation. It is certain in Catholic theology that, since Mary gave birth to the Redeemer, who is source of all grace, she is in this way the channel of all graces to mankind. But it is only probable, as a legitimate opinion, that **since Mary’s Assumption into heaven no grace is received by humans without her actual intercessory co-operation.
**
On the first level of mediation, Mary freely co-operated with God in consenting to the Incarnation, giving birth to her Son and thus sharing with him in spirit the labors of his passion and death. Yet Christ alone truly offered the sacrifice of atonement on the Cross. Mary gave him moral support in this action. She is therefore not entitled to the name “priest,” as several Roman documents legislate. As explained by the Council of Florence in 1441, Christ “conquered the enemy of the human race alone” (Denzinger, 1347). In the same way he alone acquired the grace of redemption for the whole human race, including Mary. Her part in the objective redemption, therefore, was indirect and remote, and derived from her voluntary devotion to the service of Christ. Under the Cross she suffered and sacrificed with him, but subordinate to him in such a way that all the efficacy of her oblation depended on that of her Son.
On the second stage of mediation, Mary co-operates by her maternal intercession in applying Christ’s redemptive grace to human beings, called the subjective redemption. This does not imply that the faithful must pray for all graces through Mary, nor that her intercession is inherently necessary for the distribution of divine blessing, but that, according to God’s special ordinance, the graces merited by Christ are conferred through the actual intercessory mediation of his mother. Recent popes and the Second Vatican Council have spoken in favor of this type of mediation, which finds support in patristic tradition.
This summary is similar to that of Dr. Ludwig Ott in his *Fundamentals of Catholic Dogma. *Fr. William Most goes further to state that Mary’s redemption was more than just indirect and remote. He makes a good argument, however, one is safe in understanding that Mary’s role is *at least *that which Pope John Paul II says that it is.
