(LifeSiteNews) — On November 4, 2025, the Holy See quietly released a doctrinal note titled Mater populi fidelis, signed by Argentine Cardinal Víctor Manuel Fernández, known as “Tucho,” prefect of the Dicastery for the Doctrine of the Faith, and formally approved and signed by Pope Leo XIV himself.

The note might have passed as just another technical clarification had it not contained a statement that exploded across the Catholic world: the document declares that using the title “Co-redemptrix” for the Virgin Mary is “always inappropriate.” It goes on to say that the title “Mediatrix of All Graces,” likewise applied to Mary for more than a century in magisterial teachings, is also “always inappropriate.”

“Always,” the text insists. And that adverb, repeated and underscored, has become the epicenter of a storm.

For many Catholics raised in traditional doctrine and devotion, this is not just a minor modification in vocabulary. It is the deliberate downgrading of the traditional theology of Mary’s cooperation in salvation, taught as part of the faith itself. Until now, that is.

When ‘always’ suddenly means ‘sometimes’

The backlash was immediate and intense enough that Cdl. Fernández was forced to offer public clarifications. Instead of calm, however, his explanations deepened the sense of scandal and distress.

Although the document says, “always inappropriate”, the cardinal has suggested that “always” does not mean always, but rather refers to certain contexts – above all, the liturgy and official Vatican documents. In other words, the faithful can continue using the titles Co-redemptrix and Mediatrix in personal devotion, as long as they do not expect to hear them anymore in the Church’s official prayers or in its formal texts.

Of course, faithful Catholics point out that this is precisely the problem. If the titles are doctrinally sound, why banish them from the liturgy and from official language? And if they are not sound, why tolerate them at all?

The result, many decry, is yet another troubling example of a “magisterium of ambiguity”: words that say one thing, explanations that mean another, and a widening and distressing gap between what Catholics have long been taught to believe and what they have been hearing from Rome since Vatican II adjourned in 1965.

A laywoman’s alarm: ‘So we’ve been taught something inconvenient all our lives?’

To understand why this so deeply scandalizes and offends at the grassroots, we spoke not to a theologian or a bishop, but to a laywoman in her 70s: a believing, practicing Catholic, born in the 1950s, who received solid catechesis as a child and has lived her faith with serious reflection.

She describes the Marian doctrine she learned as a girl:

We were always taught that the only Redeemer is Jesus Christ, of course. However, we were also taught that Our Lady helped in the work of redemption from the moment she accepted to be the Mother of the Savior and said, “Be it done unto me.” She was always at His side – from conception and birth to the Cross. That means she helped in the work of redemption.

We were taught that Mary is the human being who has most collaborated with that work. Not that she redeemed the human race, not at all – but without her, Christ could not have become man. He needed a human person to become human. If she had not given her consent, how could the Second Person of the Trinity have become man? She had to cooperate. That is why she is Co-redemptrix.

Her conclusion is blunt: “Now, the Vatican is telling us that it is inappropriate to call Mary Co-redemptrix. This means that all our lives we were taught something ‘inconvenient.’ That is extremely serious.”

For this Catholic lady, this is not a peripheral issue. “It’s like tearing down a truth of the Catholic Church,” she says, “a truth accepted since the earliest days of Christianity, when we are taught that Mary was already there at Pentecost.”

Cooperation or passivity? A deeper theological fault line

Behind what Catholics see as an “attack” on long-settled Marian titles and devotions lies a more basic question: Can human beings truly cooperate in their own salvation? Or is everything purely passive on our side?

Catholic tradition, in contrast to almost all Protestant currents, has always affirmed that while Christ alone is Redeemer, human beings are called to cooperate, by grace, in their own sanctification – and even, in a subordinate way, in the salvation of others through prayer, sacrifice, and works of charity.

Mary, in this view, is the model and summit of such cooperation. Her “yes” at the Annunciation and her fidelity at the foot of the Cross are considered the highest human participation in the work of Christ. From that comes the language of Mediatrix and Co-redemptrix – not as rivals to Christ, but as ways of expressing that her role is uniquely real, though entirely dependent on Him.

Our lay interviewee fears that if this cooperation is minimized in Mary, it will be minimized in everyone:

If we strip the Virgin Mary of that merit, we strip it from ourselves. Because if Christ is the only Redeemer and we have no possibility of helping in that redemption, then we have morphed into Protestants. Catholicism has always taught that we must do our part to be saved. Otherwise, we can do all the evil we want and it doesn’t matter – God will forgive us anyway.

This is what she finds most dangerous as well as spiritually draining: a drift from a vibrant faith where works, sacraments, and sacrifice have real meaning, toward vague, sentimental feelings with no consequences.

The ecumenical tightrope – or a doctrinal surrender?

The official rationale for scrapping the Marian titles is often framed in terms of so-called “ecumenism.” The alleged concern is that language like Co-redemptrix or Mediatrix of All Graces alienates Protestants, who adamantly reject Catholic teaching on Mary. But for faithful Catholics obedient to the Magisterium and Tradition, that line of reasoning gets things exactly backwards.

“An ecumenism that silences Catholic truth is not unity,” says our interviewee. “It’s corruption.”

Catholics like her argue that genuine dialogue requires clarity, not vagueness, ambiguity, or self-censorship. Just as no serious dialogue with Muslims would demand that they deny the prophethood of Muhammad, no honest dialogue with Protestants should demand that Catholics dilute, minimize, or conceal their filial piety or devotion to Mary – or any other articles of faith.

Here, the concern is not simply about vocabulary. It is about churchmen who appear more anxious about media applause and interreligious diplomacy than about teaching the faith boldly, faithfully, and unapologetically.

“Instead of affirming Catholic truth with clarity and charity,” our interviewee laments, “they disguise it to corruptly fit the narrative of anti-Catholic postmodern relativism. Instead of catechizing the faithful, they sell out doctrine and surrender the faith.”

In that sense, Mater populi fidelis is seen not as a one-off misstep, but as part of a recurring, scandalous Vatican pattern: encouraging “blessings” that are not blessings for “couples” that are not couples; saying “always” but meaning sometimes, and using formulas that undermine the faith and leave the faithful shocked, lost, and confused.

‘Every Marian truth upholds a Christological truth’

This unease is not limited to laypeople. Bishops and theologians, too, have spoken out forcefully against this deleterious decision to throw out the titles Mediatrix and Co-redemptrix.

One bishop warns that discarding them “is not merely a linguistic question, but part of a broader campaign to strip the faith of its supernatural claims and make the Church appear harmless to a world that hates the Cross.” Mary, he insists, is “the most perfect human reflection of divine truth. To diminish her role is to diminish the reality of grace itself. When her exalted titles are deemed ‘inappropriate,’ it is not she who is truly diminished, but our understanding of Christ, because every Marian truth safeguards a Christological truth.”

Another highly respected theologian notes that the problem stems from an incredible ignorance of the prefix co- in co-redemptrix:

Co- does not mean “equal to,” but “with.” In Latin, cum. Mary is not a rival redeemer. All her participation is dependent, derivative, subordinate – yet profoundly real. Her greatness does not compete with Christ. It displays the fullness of what His grace can accomplish in a human creature entirely open to God.

Why this shocking attack against Mary?

Defenders of Mater populi fidelis say that so-called “pastoral prudence” justifies avoiding terms that could “alienate” or “stoke differences.” Critics counter that everything in Catholic theology potentially alienates or causes controversy among those opposed to the faith or who do not understand it.

“Immaculate Conception,” “Assumption,” “Transubstantiation,” “the Trinity” itself – none of these expressions are self-evident or easily understood. Yet, the Church’s traditional response has never been to eliminate them, but to teach them clearly. If Mediatrix and Co-redemptrix require good catechesis, Catholics faithful to Tradition say, the answer is not to reject them, but to evangelize and preach them better.

A faith that survives by systematically degrading its linguistic and doctrinal profile, they argue, may get short-term applause, but only at the price of long-term harm to the Church. Since the Second Vatican Council, weak, compromised churchmen have been speaking a language that no longer calls the world to conversion and no longer faithfully or fully expresses what the Church has always believed and preached. Simply put, a faith that stops defending its mysteries soon stops believing in them.

More than devotion: An anthropological crisis

The implications, of course, go beyond Marian devotion. What is at stake, many faithful Catholics insist, is the entire Catholic vision of Christ, the Church, and the human person.

If Mary is no longer presented as the great collaborator in the work of redemption, if works, dogmas, and sacraments are to be treated as mere “symbols” or subjective “feelings,” then the Catholic principle that our deeds matter eternally has been hollowed out. What remains is a kind of insipid, meaningless sentimentality: rituals designed to soothe or appease the conscience, instead of sacraments that uplift and transform the soul.

“Catholicism is not a sentimental religion,” our interviewee insists. “Being Catholic is not just having nice humanitarian feelings. It is difficult and challenging, at best. What is at stake is a whole anthropological conception shaped by centuries of Catholic thought – a way of being in the world, of reasoning, of interpreting reality.”

In that light, disputes over titles like Mediatrix and Co-redemptrix are not trivial. They are flashpoints in a wider struggle over whether Catholicism will remain a sacramental, incarnational faith – or morph completely into a spineless, harmless religious sect that offends no one and saves no one.

An imposter ‘church’ replaces the real?

Some saints and thinkers long ago warned of a “false or counterfeit church” that would imitate the true Church while emptying it from within – maintaining the external appearance while imposing a new liturgy, theological language, and corrupt hierarchy, gutted of its supernatural content.

For alert Catholics who see through this charade of post Vatican II creation, Mater populi fidelis is simply another glaring sign of that very serious danger: a “church” that deceptively keeps Marian images, hymns, and feasts, but progressively strips them of their doctrinal depth and meaning; a “church” where some familiar vocabulary survives, but core beliefs and teachings are watered down, blurred, or falsified.

“When the Mother is silenced,” one Catholic bishop warns, “the Cross soon follows. When grace is replaced by pop psychology, the sacraments become mere symbols, and the faith becomes a tranquilizing placebo.”

In such an imposter, pseudo-church, Mary stops being the woman who crushes the serpent’s head and becomes something like a meaningless poetic metaphor. The Holy Eucharist stops being the unbloody sacrifice of Calvary to become a happy communal meal. The Church stops being the Ark of Salvation to become a secular NGO with incense.

‘Light of the world’ or harmless night-light?

That is why Catholics, both lay and ordained alike, are as outraged as alarmed, and why the headline they propose is so stark: “An ecumenism that silences the truth is not ecumenism. It’s corruption.”

For them, genuine Catholic ecumenism means showing the face of Christ and His Mother as the Church has always believed and revered them – clearly, unapologetically, with charity but without any disguise. It means inviting non-believers to see the fullness of grace at work in Mary, not concealing her richly deserved titles out of embarrassment.

“Jesus said we must be the light of the world and the salt of the earth,” one traditional Catholic recalls. Light is meant to shine, not be dimmed for fear of offending. Salt is meant to preserve from corruption, not dissolve into uselessness.

Were Catholics to forget this, the argument goes, they do not become more charitable or more united. They would become, in the famous phrase, “tasteless, useless, harmless – or worse, useful fools.”

A wake-up call

The debate over Mater populi fidelis and the titles of Mary is far from over. Nor is it merely about sentiment, piety, or “private devotion.” This “doctrinal note” forces the Church to ask itself what kind of faith it intends to offer the world: a solidly grounded, supernatural vision that demands conversion, or a shallow, adaptable pseudo-religion that comforts but does not energize or transform.

At least one thing is clear: millions of faithful Catholics are not ready to quietly let go of the language taught to them as children – language that shapes their understanding of Christ, Mary, and themselves. They are not willing to trade a robust, demanding creed for a vague, empty spiritualism. And they are not convinced that pleasing the world is worth the price of disrespecting the Mother of God. For them, the line is non-negotiable: an ecumenism that silences the truth is not ecumenism. It’s corruption.

And they intend to say so – loudly, proudly, and unwaveringly. While they still can.
