In the previous article, we saw that Jesus did not push Mary aside when He blessed those who hear the word of God and keep it. He revealed the deepest reason she is blessed: Mary received the word in faith and kept it all the way to the Cross. We now turn from her life as the first disciple to the prayers she offers as a living member of Christ’s Body.

If Jesus Christ is the one Mediator between God and humanity, can Mary or any saint truly intercede for us? Does asking for her prayers place another figure between the believer and Christ? Or does Christ’s perfect mediation create the communion in which His members can pray for one another?

I. Christ Is the One Mediator

This brings us, with some trepidation, to a boundary that governs this entire series and must be stated explicitly: Mary’s intercession does not replace, rival, or compete with the one mediation of Jesus Christ.

St. Paul says plainly, “There is one God, and there is one mediator between God and men, the man Christ Jesus” (1 Timothy 2:5). Catholics believe that completely. Christ alone is the Mediator in the absolute sense, because Christ alone is true God and true man. Christ alone reconciles humanity to the Father by His Incarnation, Passion, Death, Resurrection, and Ascension. Christ alone offers the sacrifice that saves. Christ alone is the Redeemer.

So if someone means by “mediator” another redeemer, another savior, another source of grace, or another person who stands beside Christ as though Christ were insufficient, then Mary is not that. No saint is that. No priest is that. No member of the Church is that.

II. One Mediation, Shared Prayer

But Scripture itself also teaches that Christ’s one mediation does not eliminate subordinate participation in His work. In fact, St. Paul urges Christians to offer “supplications, prayers, intercessions, and thanksgivings” for all men immediately before saying that Christ is the one mediator (1 Timothy 2:1–5). That means Paul does not see Christian intercession as a violation of Christ’s unique mediation. He sees it as something that belongs within it.

This is the Catholic distinction. Christ’s mediation is unique, sufficient, and saving. Our intercession is subordinate, dependent, and participatory. We do not pray for one another because Christ is lacking. We pray for one another because Christ allows His members to participate in His love for the Body.

This is already how Christians live. When we ask another believer to pray for us, we are not denying that Christ is the one Mediator. When we pray for our families, we are not replacing Christ. If a priest prays for the faithful, he is not becoming a second redeemer. Christian intercession does not compete with Christ when it depends entirely upon Christ.

III. The Saints Still Pray in Christ

This is the doctrine of the Communion of Saints. The Body of Christ is not limited to those still living on earth. It includes those who have died in Christ and now stand before Him in glory. Death does not sever membership in the Body, and it does not silence prayer. The saints in heaven are more alive in Christ than they were on earth, and their intercession, like ours, flows from Him and returns to Him.

Mary’s intercession belongs to that same order, though in a unique maternal way. She is not another mediator beside Christ. She is a member of Christ’s Body, wholly redeemed by Him, wholly dependent upon Him, and uniquely united to His saving mission as His Mother. Her intercession has no power of its own apart from Christ. It draws all its power from Him.

IV. All Her Help Comes from Christ

This is exactly how the Church teaches it. Lumen Gentium §60 says that Mary’s maternal role “in no way obscures or diminishes this unique mediation of Christ, but rather shows its power.” It then adds that her 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.” The Catechism repeats this same teaching in CCC 970.

The Dicastery for the Doctrine of the Faith’s 2025 doctrinal note Mater Populi Fidelis makes this boundary even more explicit. It calls Scripture’s teaching about Christ’s exclusive mediation conclusive and requires “special prudence” when the title Mediatrix is applied to Mary (§24). The title may express subordinate cooperation, assistance, or intercession, but it cannot add any power or efficacy to the unique mediation of Jesus Christ (§§25–26). For this reason, the Second Vatican Council preferred expressions such as “manifold intercession” and “maternal help” (§27).

Strictly speaking, there is no mediation in grace apart from that of the Incarnate Son. Yet Christ’s unique mediation is so powerful that it permits His members to participate in His work without becoming rivals to Him. Their cooperation arises from His mediation, depends upon His power, and remains a sharing in the one source (§§27–29).

The note also distinguishes Mary’s maternal intercession from God’s direct gift of sanctifying grace. No creature, including Mary, can confer sanctifying grace or act as its universal dispenser. God alone enters the soul, justifies it, and gives His divine life. Mary may intercede for the helps traditionally called actual graces and assist in preparing our hearts to receive what the Lord alone bestows (§§50–53, 67–70). Her maternal help is therefore real, but it never becomes a barrier between the believer and Christ.

Pope Leo XIV reaffirmed this teaching on May 13, 2026. Jesus Christ is the sole Mediator of salvation, while Mary’s maternal role “in no way impedes, but rather fosters the immediate union of the faithful with Christ.” Her intercession does not place distance between the Christian and the Lord. It seeks a deeper and more immediate union with Him.

That means Mary’s intercession is not a Catholic workaround around Jesus. It is not going to Mary because Jesus is too distant, too stern, or too unwilling to hear us. That would be a distortion of Catholic doctrine. The Father is not reluctant. The Son is not reluctant. The Holy Spirit is not reluctant. God is not less merciful than Mary.

V. True Devotion Leads to Christ

And this concern is not a Protestant concern only. It is a Catholic concern too. Some of the saints who wrote most warmly about Mary also insisted that true devotion to her must lead the soul to Christ. St. Bernard’s famous exhortation to “look to the star” and call upon Mary in danger, doubt, and difficulty was never meant to make Mary a replacement for the Lord, but to lead the soul safely to Him. St. Alphonsus Liguori wrote with extraordinary confidence about Mary’s maternal help, yet his whole Marian theology presupposes that every grace comes from God and that Mary’s power is intercessory, not divine. St. Louis de Montfort says this most directly: “You never praise or honour Mary without Mary joining you in praising and honouring God. Mary is entirely relative to God… because she exists uniquely in reference to him.”

St. Louis de Montfort’s witness is especially revealing because he is the same saint who gave the Church one of her most thoroughgoing forms of Marian devotion: total consecration to Jesus through Mary. The very saint who spoke so insistently about belonging to Mary understood that authentic consecration through her terminates in Christ, not in Mary as an end in herself. The man who loved her with such intensity knew exactly where she points. He even said in his own work, True Devotion to Mary:

"With the whole Church I acknowledge that Mary, being a mere creature fashioned by the hands of God is, compared to his infinite majesty, less than an atom, or rather is simply nothing, since he alone can say, 'I am he who is'." (TD 14)

St. Louis de Montfort could therefore speak of Mary so boldly precisely because he never confused her with God: every greatness he saw in her was God’s gift and remained ordered entirely to the glory of Christ.

That is the Catholic standard for Marian devotion: if it terminates in Mary, it has gone wrong; if it leads through Mary to deeper obedience, trust, and love for Christ, it is doing what authentic Marian devotion is meant to do. This is why Pope St. John Paul II considered St. Louis de Montfort’s teaching so important that he chose Totus Tuus, “Totally Yours,” as his papal motto, drawn from de Montfort’s spirituality of total consecration to Jesus through Mary.

So, regarding whether this is disputed within the Catholic Church: Catholics may dispute how best to phrase Marian devotion, which titles are pastorally helpful, and whether some devotional language is too imprecise. But the Church does not dispute the underlying doctrine that Mary’s maternal intercession is real, subordinate to Christ, and dependent entirely upon His one mediation.

Mary’s intercession is better understood as the fruit of Christ’s generosity. The Son who alone saves allows His mother, and all His saints, to share in His concern for His members. Their prayers do not make Christ merciful. Their prayers manifest the mercy of Christ already at work in His Body.

VI. At Cana, Mary Brings the Need

The wedding at Cana gives us a biblical image of this. Mary notices the need and says to Jesus, “They have no wine” (John 2:3). She does not command Him. She does not override His will. She simply brings the need before Him. Jesus responds freely and sovereignly, and the miracle that follows reveals His glory (John 2:11). Mary’s role is entirely ordered toward Him. Her last recorded words in Scripture are not, “Come to me,” but, “Do whatever he tells you” (John 2:5).

That is the whole logic of Marian intercession. Mary brings needs to Christ, and then directs everyone back to obedience to Christ.

VII. What the Marian Titles Mean

So when the Church invokes Mary as Advocate, Helper, Benefactress, or Mediatrix, those titles must be understood the way the Church herself defines them. Lumen Gentium §62 says they are “so understood that it neither takes away anything from nor adds anything to the dignity and efficacy of Christ the one Mediator.” In other words, the Church does not ask us to choose between Christ’s mediation and Mary’s intercession. The Church insists that Mary’s intercession only has meaning because Christ’s mediation is perfect.

So the question is not whether Mary’s intercession competes with Christ. Properly understood, it cannot. The question is whether Christ’s one mediation is so powerful that it can make room for His members to pray for one another without becoming rivals to Him. Scripture says yes. The Church says yes.

Mary brings needs to Christ. She directs everyone to obedience to Christ. And she does this not because Christ is insufficient, but because the Son who alone saves has made His mother the one through whom, at the first miracle of His public ministry, He chose to let His glory be revealed, so that “his disciples believed in him” (John 2:11).

In Summary

Jesus Christ is the one Mediator in the absolute and saving sense. He alone is true God and true man. He alone reconciles humanity to the Father through His Incarnation, Passion, Death, Resurrection, and Ascension. The prayers of Christians do not add to His saving work. They participate in the charity His one mediation creates within His Body.

Mary’s intercession belongs within the Communion of Saints. Its maternal character is unique, but its power is entirely received from Christ. She neither confers sanctifying grace nor stands between the believer and direct access to God. She brings our needs to her Son, helps prepare our hearts to receive what God alone gives, and repeats the command of Cana: “Do whatever he tells you.”

In the next article, we will distinguish honor from adoration. What do Catholics mean by latria, dulia, and hyperdulia? Why does the Catechism say devotion to Mary differs essentially from worship of God? And what should Catholics say when the title “Queen of Heaven” is compared to the idolatry condemned by Jeremiah?

Until we meet again, go forth in the peace of Christ. Seek truth over victory, speak with charity, and magnify the Lord. Read on.
