. . . The six prelates believe the new dogma will help to complete the Church’s teaching about Mary, which is already expressed by the four dogmas of her perpetual virginity, her dignity as the Mother of God, her Immaculate Conception, and her glorious Assumption body and soul into heaven. What is needed is a solemn affirmation of the Virgin Mary’s “human but crucial role in God’s plan of salvation, as the New Eve next to the New Adam, as the Spiritual Mother of all humanity.”
The petition of the six bishops to define Mary’s coredemptive role is not the first time this has been proposed. During Vatican I (1869–1870), the French bishop, Jean Laurent, requested a dogmatic definition of Mary as Coredemptrix. The Council, though, did not believe the theology of Marian coredemption was sufficiently mature to make a formal statement. . . .
. . . John XXIII, however, did not want any new definitions made at the Council. The Blessed Mother is not referred to as Coredemptrix in chapter eight of Lumen gentium (which is on Mary). She is, however, referred to as Mediatrix in Lumen gentium, 62, but not Mediatrix of all graces. The 1962 draft on Mary (which formed the basis for Lumen gentium, chapter eight of 1964) referred to Mary as the Mediatrix of all graces, and it referred to her as “Coredemptrix” in two footnotes. Because of ecumenical concerns, however, the footnotes to Mary as Coredemptrix were dropped, and the title, Mediatrix of all graces was changed to simply “Mediatrix.”
Although Vatican II chose not to refer to Mary as Coredemptrix, some theologians, such as Jean Galot, S.J and Georges Cottier, O.P., have argued that Lumen gentium affirms the doctrine of Marian coredemption without using the title, Coredemptrix (see Galot in La Civilità Cattolica [1994] III: 236-237 and Cottier, in L’Osservatore Romano, June 4, 2002). Pius XI (r. 1922–1939) was the first Pope to refer publicly to Mary as Coredemptrix, and John Paul II publicly called Mary “Coredemptrix” at least six times, and he called Mary “Mediatrix of all graces” at least seven times. Benedict XVI also referred to Mary as “Mediatrix of all graces” in his January 10, 2012 letter to Archbishop Zimowski, who was representing the Holy See for the World Day of the Sick . . . .
. . . . Some Catholics, however, have reservations about the wisdom of such a dogmatic proclamation. In August 1996, during the twelfth International Mariological Congress held at Częstochowa (Poland), a group of 23 theologians—including three Orthodox, one Anglican, and one Lutheran—met briefly and issued a statement advising against the dogmatic proclamation. In addition to ecumenical concerns, they said Marian titles such as “Coredemptrix’ were ‘ambiguous’ and in need of greater study and clarification (L’Osservatore Romano June 4, 1997).
This non-magisterial judgment of an ad hoc group of theologians has not stopped those favoring the dogmatic proclamation. . . .
