Popes declaring Mary co-redeemer / co-redemptrix / co-savior
"Who can worthily thank thee and adequately praise thee, oh Blessed Virgin, who by thy fiat has saved a lost world." St. Augustine
"The foundation of all our confidence is found in the Blessed Virgin Mary. God has committed to her the treasury of all good things, in order that everyone may know that through her are obtained every hope, every grace, and all salvation. For this is His will: That we obtain everything through Mary." Pope Pius IX
"Sinners receive pardon by the intercession of Mary alone." St. John Chrysostom
"All those who seek Mary’s protection will be saved for all eternity." Pope Benedict XV
Leo XIII, Jucunda Semper, 1894: "When Mary offered herself completely to God together with her Son in the temple, she was already sharing with him the painful atonement on behalf of the human race ... (at the foot of cross) she willingly offered him up to the divine justice, dying with him in her heart, pierced by the sword of sorrow."
Pius X, Ad Diem Illum, 1904: "Owing to the union of suffering and purpose existing between Christ and Mary, she merited to become most worthily the reparatrix of the lost world, and for this reason, the dispenser of ALL favors which Jesus acquired for us by his death . . .
Benedict XV, Inter Sodalicia, 1918: "To such extent did Mary suffer and almost die with her suffering and dying Son; to such extent did she surrender her maternal rights over her Son for : man's salvation . . that we may rightly say she redeemed the human race together with Christ."
Plus XI, 1935, in a prayer to close a jubilee, we find the first use of the word Coredemptrix by a pope: "O Mother of love and mercy who, when thy sweetest Son was consummating the Redemption of the human race on in the altar of the cross, didst stand next to him suffering with him as a Coredemptrix."
Plus XII, in a radio broadcast in 1946: "Mary, for having been associated with the King of Martyrs in the ineffable work of human Redemption as Mother and cooperatrix, she remains forever associated with him, with an almost unlimited power, in the distribution of graces which flow from the Redemption."
John XXIII, Vatican II's Lumen Gentium, 1965.
Paul VI, Christi Matri. "The Church ... been accustomed to have recourse to that most ready intercessor, her Mother Mary ... For as St. Irenaeus says, she 'has become the cause of salvation for the whole human race"
John Paul II, Mother of the Redeemer, 1987.
Pius IX, Ubi Primum, 1849: "For God has committed to Mary the treasury of all good things, in order that everyone may know that THROUGH HER are obtained every hope, every grace, and ALL SALVATION. For this is his will, that we obtain everything through Mary."
Leo XIII, Supremi Apostolatus, 1883: "O Mary, the guardian of our peace and the dispensatrix of heavenly graces."
Plus X, Ad Diem Illum, 1904: "It was granted to the august Virgin to be together with her Only-begotten Son the most powerful Mediatrix and Conciliatrix of the whole world. So Christ is the source . . . Mary, however, as St. Bernard justly remarks, is the channel, or she is the neck by which the Body is united to the Head... through which ALL spiritual gifts are communicated to his Body."
Benedict XV, In a decree on Joan of Are: "In every miracle we must recognize the mediation of Mary, through whom, according to God's will, every grace and blessing comes to us."
Plus XI, Miserentissimus Redemptor, 1928: "Confiding in her intercession with Jesus, "the one Mediator of God and man, who wished to associate his own Mother with himself as the advocate of sinners, as the dispenser and mediatrix of grace."
Plus XII, Superiore Anno, 1940: "As St. Bernard declares, 'it is the will of God that we obtain favors through Mary, let everyone hasten to have recourse to Mary."

John Paul II, Dives in Misericordia, 1980, quoting Lumen Gentium, "In fact, by being assumed into heaven she has not laid aside the office of salvation but by the manifold intercession she continues to obtain for us the grace of eternal salvation."
