- QUESTION : The Doctrinal Note “Mater Populi Fidelis,” published on 4 November by Dicastery for the Doctrine of the Faith sparked the ecclesial debate. Mary does not replace Christ. Now how should one understand Mother Mary’s role in God’s plan for salvation? – Ann Maria
ANSWER : Jacob Parappally MSFS
On 4 November 2025, the Dicastery for the Doctrine of the Faith published a Doctrinal Note titled Mater Populi Fidelis on “Some Marian Titles Regarding Mary’s Cooperation in the Work of Salvation,” signed by Pope Leo XIV. This document has prompted renewed theological and pastoral debate concerning the role of the Blessed Virgin Mary, the Mother of God, in the history of salvation. In a context marked by exaggerated forms of Marian devotion, forms that sometimes give non-Catholics and even some Catholics the impression that Mary’s role is equal to that of Christ, there was a need for clarification. The Doctrinal Note seeks precisely to present clearly the Church’s authentic teaching on this matter to both the Catholic faithful and others.
The Doctrinal Note (MPF) reaffirms the Church’s traditional teaching that Mary in no way replaces the unique mediation of Christ, and that popular excesses in Marian devotion can obscure this truth of Christian salvation. At the same time, the Note clarifies that the Blessed Virgin Mary has, above all other human beings, a real participatory role in the economy of salvation. This cooperation is genuine yet subordinate to the unique mediation of Jesus Christ. All human beings must cooperate with Christ for their salvation; unlike others, Mary also cooperated with God in bringing forth the Son of God into the world. This cooperation is unique, a grace granted to Mary alone. As the Note states: “This cooperation, made possible through Christ and stirred up by the Spirit’s action, is, in Mary’s case, distinguished from the cooperation of any other human being due to the maternal character that Christ himself conferred upon her while on the cross” (MPF 64). Mary’s role in salvation history must therefore be understood as a form of participatory mediation, integrally linked to the mediation of the Church of which she is both icon and Mother. While her role is entirely graced, the faithful must not think or imply that Mary’s participation in the plan of salvation in any way diminishes the role of Jesus Christ, the sole Mediator, of whom St Paul says: “There is only one mediator between God and humans, the man Christ Jesus” (1 Tim 2:5).
The Context of the Doctrinal Note on Marian Mediation
The introduction of the Doctrinal Note explains that its publication was prompted by requests from some of the faithful to promote certain Marian titles that have raised theological and pastoral concerns. It is undeniable that certain exaggerated expressions of Marian devotion have created the impression among some Catholics that Mary is equal to Jesus, and sometimes, regrettably, even superior to him in answering prayers. This impression may be unintentionally reinforced by the Church’s liturgical tradition, which includes Marian feasts that appear parallel to the feasts and solemnities of Jesus: Christmas and the Nativity of Our Lady; Christ the King and the Queenship of Mary; the Ascension of the Lord and the Assumption of Mary; the Sacred Heart of Jesus and the Immaculate Heart of Mary, along with many other Marian feasts. Additionally, the numerous Marian memorials, optional memorials, and the tradition of celebrating Mass in honour of Mary on most Saturdays can influence popular piety in ways that appear to equalize Mary with Christ.
The Second Vatican Council offers a balanced approach, avoiding both maximalist exaggeration and minimalist reduction. In Lumen Gentium (Dogmatic Constitution on Church), Mary is presented as Daughter of Zion, Mother of the Redeemer, first disciple, Image of the Church, and eschatological icon of hope. Her role flows from and is ordered to Christ’s unique mediation.
Although the Church does not encourage exaggerated devotion to Mary, she nonetheless holds a special place in the hearts of many who seek her intercession. In a context where God is often imagined in exclusively masculine imagery, some believers unfortunately come to view Mary as the feminine dimension of God. Pope Paul VI’s Apostolic Exhortation Marialis Cultus warns against replacing the Holy Spirit with Mary or attributing to Mary functions belonging properly to the Spirit. It states: “The Church’s devotion to the Blessed Virgin cannot ignore the Holy Spirit… Marian devotion must develop along the line laid down by the Spirit… It must not present Mary as an alternative to the Spirit or obscure His action” (MC 38). It also warns against theological exaggerations: Mary is a creature, not divine; she is redeemed by Christ, dependent entirely on God’s grace, and the model of the Church. Exaggerated statements that present Mary as “the mediatrix of all graces” risk obscuring Christ’s unique role.
The Doctrinal Note (MPF), therefore, aims not to suppress Marian devotion but to clarify which titles and expressions are theologically sound and firmly grounded in Christology, ecclesiology, and Scripture, so that Marian devotion does not overshadow or distort the unique role of Christ. While affirming the legitimate place of Marian piety, the Note warns against devotional practices, publications, or new “dogmatic developments” (especially via social media) that exceed what is doctrinally clear or safe.
Jesus Christ, the Unique Mediator
The teaching of the Catholic Church, based on the apostolic witness of the New Testament, affirms that Jesus Christ is the sole mediator of human salvation: “For there is one God and one mediator between God and men, the man Christ Jesus” (1 Tim 2:5). No creature can diminish or obscure this unique mediation. The Catechism of the Catholic Church teaches: “Mary’s function as mother of men in no way obscures or diminishes this unique mediation of Christ, but rather shows its power… The Blessed Virgin’s salutary influence… flows forth from the superabundance of the merits of Christ, rests on his mediation, depends entirely on it, and draws all its power from it…. No creature could ever be counted along with the Incarnate Word and Redeemer” (CCC 970).
Even among those who advocate for the titles “Mediatrix” or “Co-redemptrix,” many insist that these titles should not obscure Christ’s unique mediation. A California-based group, Vox Populi Mariae Mediatrici, begins one of its publications with this clarification: “The salvation of humanity was accomplished by God’s only begotten Son, Jesus Christ…. The Passion and Death of Christ, our sole Redeemer, was not only sufficient but ‘superabundant’ satisfaction for human guilt.” The unique and exclusive mediation of Christ is non-negotiable. The Doctrinal Note emphasizes this strongly, warning against two dangers: Attributing to Mary what belongs exclusively to Christ. Denying the genuine participatory role of Mary or of the faithful in the economy of salvation. Vatican II affirms the same truth: “The maternal role of Mary… neither takes away from nor adds anything to the dignity and efficacy of Christ the one Mediator” (Lumen Gentium 62). Christocentrism is the foundation that enables Mary’s maternal mission in the Church.
Mary in the New Testament, Patristic Theology, and Liturgy
The New Testament presents Mary as the model of obedient faith. Her role in salvation history begins with her fiat, her “yes” to God (Lk 1:38). The Annunciation narrative reveals God’s profound respect for human freedom. Mary’s consent is her unique cooperation in God’s salvific plan. At the Visitation, she brings Christ to Elizabeth, symbolizing the Church’s mission to bring Christ to all peoples. At the Cross, she receives a new mission as spiritual mother of all disciples (Jn 19:25–27). At Pentecost, she is present in the Upper Room, symbolizing her continuing solidarity with the Church. The New Testament does not present Mary as an alternative mediator but as a perfect disciple whose cooperation exemplifies how the Church is to receive and proclaim salvation through Christ in the Holy Spirit.
The Doctrinal Note (MPF), therefore, aims not to suppress Marian devotion but to clarify which titles and expressions are theologically sound and firmly grounded in Christology, ecclesiology, and Scripture, so that Marian devotion does not overshadow or distort the unique role of Christ.
The Fathers of the Church, especially Irenaeus, Justin Martyr, and Ephrem, recognized Mary’s role in salvation history and presented her as the “New Eve,” whose obedience reversed Eve’s disobedience. Marian theology in the Patristic era focused not on sentimental piety but on Mary as the symbol of redeemed humanity. The Council of Ephesus (431), in declaring Mary Theotokos (Mother of God), affirmed that the one born of Mary is truly God. Nestorius feared this title would lead to Mary being viewed as a goddess, a fear not unfounded, since certain forms of devotion later approached such exaggeration.
In the Middle Ages, titles such as Mediatrix and Queen of Heaven flourished. Excesses in Marian devotion contributed to the Reformers’ rejection of Marian intercession, as they emphasized sola gratia and denied all human cooperation in salvation. The Catholic Counter-Reformation sometimes responded with an overemphasis in the opposite direction. The later Marian dogmas of the Immaculate Conception (1854) and the Assumption (1950), though properly understood as affirmations of God’s grace, nonetheless posed ecumenical challenges. A balanced approach was restored at Vatican II. Although the liturgical traditions of East and West include many Marian feasts, none replace Christ’s unique role. Even in liturgies honouring Mary, the centre remains Jesus Christ, whose Body and Blood are shared and whose disciples are called to imitate Mary’s obedience.
Maximalists and Minimalists in Mariology
Maximalists emphasize Mary’s privileges, her full cooperation with Christ, and her universal maternal mediation. They highlight her role as New Eve and her participation in the mystery of redemption, subordinate yet closely united to Christ. They support titles such as Co-redemptrix, Mediatrix of all Graces, and Advocate. Writers like St Louis-Marie de Montfort and St Alphonsus Liguori often reflect this approach. While this view fosters devotion and imitates Mary’s virtues, it risks overshadowing Christ’s centrality, creating ecumenical difficulties, encouraging unbalanced devotional practices, and placing Mary psychologically between Christ and the faithful.
Minimalists, by contrast, take a restrained approach, presenting Mary primarily as the first disciple, a biblical and patristic figure of faith. They affirm Mary’s role in the conception and birth of Jesus but avoid attributing to her any direct participation in the work of redemption. They emphasize humility and discipleship over cosmic or universal mediation. While their perspective safeguards Christocentrism and aids ecumenical dialogue, it may diminish Mary’s significance in Catholic spirituality.
Vatican II’s Approach to Mary’s Role in the Church
The Second Vatican Council offers a balanced approach, avoiding both maximalist exaggeration and minimalist reduction. In Lumen Gentium (Dogmatic Constitution on Church), Mary is presented as Daughter of Zion, Mother of the Redeemer, first disciple, Image of the Church, and eschatological icon of hope. Her role flows from and is ordered to Christ’s unique mediation. The Council describes Mary’s mediation as: singular because of her divine motherhood, participated, because it is entirely a grace, subordinate, because it depends completely on Christ, ecclesial, because it expresses the Church’s own mission. Mary is not placed between Christ and the faithful but within the Church as its pre-eminent member and type (typus Ecclesiae). These insights are reaffirmed by the Doctrinal Note.
Clarifications of the Doctrinal Note
The Note clearly states that Mary is not “Co-redemptrix” in the strict sense, since this title could imply a role parallel to Christ. It stresses that titles such as “Mediatrix” or “Advocate” must always be understood within the framework of Christ’s sole mediation. Human beings must freely cooperate with God for salvation; as St Augustine says, “God who created you without you cannot save you without you.” Mary’s cooperation is unique because she was called to be the Mother of the Saviour and she freely consented to this grace. She cooperated not by adding to Christ’s work but by receiving it in perfect faith.
The Note warns against devotional practices that obscure Christ’s centrality. Authentic Marian piety leads the faithful to the Eucharist, Scripture, and discipleship. All Christians share in Christ’s mediation through the common priesthood (1 Pet 2:9; Rev 1:5–6) and are called to bear Christ to the world. Mary uniquely did this by giving birth to the Redeemer; all disciples do so through witness and charity. Mary’s mediation is therefore: cooperative, not competitive, participatory, not parallel, derived, not autonomous.
The use of titles such as Co-redemptrix, Mediatrix of all graces, and Advocate should be discouraged, because the faithful may place Mary on the same level as Christ or see her as replacing the role of the Holy Spirit. Grace is not a thing but a relationship of friendship with God through the Holy Spirit. Certainly, Mary cannot be the dispenser of one’s intimacy with God through the Spirit. She can, however, be a model for believers in responding to the Spirit and an intercessor who helps them deepen their openness to the Spirit.
