"To Our Lady—the Coredemptrix—St. Charles turned with singularly revealing accents. Commenting on the loss of the twelve-year-old Jesus in the Temple, he reconstructed the interior dialogue that could have run between the Mother and the Son, and he added, “You will endure much greater sorrows, O blessed Mother, and you will continue to live; but life will be for you a thousand times more bitter than death. You will see your innocent Son handed over into the hands of sinners . . . You will see him brutally crucified between thieves; you will see his holy side pierced by the cruel thrust of a lance; finally, you will see the blood that you gave him spilling. And nevertheless you will not be able to die!” (From the homily delivered in the Cathedral of Milan the Sunday after the Epiphany, 1584). (3)
Mary accompanied her divine Son in the most discreet concealment, pondering everything in the depths of her heart. On Calvary, at the foot of the Cross, in the vastness and in the depth of her maternal sacrifice, she had John, the youngest Apostle, beside her . . . .
"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. "
"Birgitta looked to Mary as her model and support in the various moments of her life. She spoke energetically about the divine privilege of Mary’s Immaculate Conception. She contemplated her astonishing mission as Mother of the Saviour. She invoked her as the Immaculate Conception, Our Lady of Sorrows, and Coredemptrix, exalting Mary’s singular role in the history of salvation and the life of the Christian people"
"Dearest brothers and sisters, in the month of May we raise our eyes to Mary, the woman who was associated in a unique way in the work of mankind’s reconciliation with God. According to the Father’s plan, Christ was to accomplish this work through his sacrifice. However, a woman would be associated with him, the Immaculate Virgin who is thus placed before our eyes as the highest model of cooperation in the work of salvation. . . .
The “Yes” of the Annunciation constituted not only the acceptance of the offered motherhood, but signified above all Mary’s commitment to service of the mystery of the Redemption. Redemption was the work of her Son; Mary was associated with it on a subordinate level. Nevertheless, her participation was real and demanding. Giving her consent to the angel’s message, Mary agreed to collaborate in the whole work of mankind’s reconciliation with God, just as her Son would accomplish it.
"Born of the Virgin to be a pure, holy and immaculate oblation, Christ offered on the Cross the one perfect Sacrifice which every Mass, in an unbloody manner, renews and makes present. In that one Sacrifice, Mary, the first redeemed, the Mother of the Church, had an active part. She stood near the Crucified, suffering deeply with her Firstborn; with a motherly heart she associated herself with his Sacrifice; with love she consented to his immolation (cf. Lumen Gentium, 58; Marialis Cultus, 20): she offered him and she offered herself to the Father. Every Eucharist is a memorial of that Sacrifice and that Passover that restored life to the world; every Mass puts us in intimate communion with her, the Mother, whose sacrifice “becomes present” just as the Sacrifice of her Son “becomes present” at the words of consecration of the bread and wine pronounced by the priest. "
Great Jubilee Year
"Daughter of Abraham in faith as well as in the flesh, Mary personally shared in this experience. Like Abraham, she too accepted the sacrifice of her Son, but while the actual sacrifice of Isaac was not demanded of Abraham, Christ drank the cup of suffering to the last drop. Mary personally took part in her Son’s trial, believing and hoping at the foot of the Cross (cf. Jn. 19:25).
This was the epilogue of a long wait. Having been taught to meditate on the prophetic texts, Mary foresaw what awaited her and in praising the mercy of God, faithful to his people from generation to generation, she gave her own consent to his plan of salvation; in particular, she said her “yes” to the central event of this plan, the sacrifice of that Child whom she bore in her womb. Like Abraham, she accepted the sacrifice of her Son."
