No commentary — my own least of all — can do complete justice to the words of the Holy Father himself. I have therefore woven links throughout this essay to Pope Leo’s own addresses, and gathered links to all eight of his catecheses on Sacrosanctum Concilium at the end, exactly as they appear on the Vatican’s website. I ask the reader to go to the source: to read the Holy Father whole, in his own words. What follows is offered as a companion to that reading, and never as a substitute for it.
In the early centuries of the Church, when the newly baptized rose dripping from the font on Easter night, their instruction was not finished but only begun. In the days that followed, the bishop would gather these newly baptized and lead them back through the mysteries they had just received — the water, the oil, the bread and the cup — unfolding what the sacred rites had worked in them and for them. This was mystagogy: the opening of the sacramental mysteries to those newly admitted to them. At Jerusalem, in the very shadow of the Anastasis, the Church of the Holy Sepulchre, Saint Cyril delivered such catecheses to his neophytes in the octave of Easter — and by God’s providence we possess them still, luminous homilies that lead the Christian from the sign he has seen to the grace he cannot. Ambrose did the same at Milan, Chrysostom for his own neophytes and Augustine in his Cathedral in Hippo. It was the golden age of the mystagogue: the bishop as the one who takes the faithful by the hand and walks them into the holy of holies.
Across these past months, Pope Leo XIV has taken up that same ancient office — only now the neophytes are the whole Church, the newly baptized and the long baptized alike. In an age that has largely lost the capacity to read its own rites, that stands before sign and symbol — as Romano Guardini lamented, and as Leo himself would recall — no longer knowing how to see, the universal pastor has become mystagogue to all the faithful, opening the riches of the sacred liturgy. He has done it not as a scholar defending a thesis, nor as a partisan in a quarrel, but as a father leading his children deeper into the mystery that feeds them. This is the pope’s pivotal office as teacher: not to win an argument, but to open a door.
For fifteen weeks, in a series broken only by a pastoral journey to Spain and the quiet of a Roman August, Pope Leo XIV gave the Church a catechesis on Sacrosanctum Concilium, the first document the Second Vatican Council promulgated and the charter of its liturgical renewal. Eight reflections in all, from the first on the twentieth of May to the last this past week. To the casual listener each Wednesday sounded like a self-contained meditation. It was only with the final catechesis that the design became visible — for Leo saved for last not a topic but a question. Having walked through the Eucharist, the Divine Office, the liturgical year, and sacred music, he closed by asking why the Council Fathers had wanted a reform at all. And in answering that question he revealed that the preceding seven reflections had been, all along, a single sustained argument.
It is worth saying plainly what that argument is, because I am convinced it is among the most consequential things Leo has yet given us — and because it was delivered against a counterpoint no one who was paying attention could ignore. On the first day of July, in a meadow at Écône, four priests of the Society of Saint Pius X were consecrated bishops without a pontifical mandate. Rome answered as she was bound to: the Holy Father declared the schism, and the Dicastery for the Doctrine of the Faith issued the decree of excommunication. The rupture many of us had prayed would be spared the Church became a canonical fact. And here is the detail that ought to capture our attention. In the document by which the Society justified its act, its authors cited Leo’s own Wednesday catechesis of January 7, in which he had called the Council the beacon that still guides the Church’s path. The very pulpit the Society invoked as proof of Rome’s intransigence was the pulpit from which, week after week, Leo was patiently unfolding the Council’s liturgical vision — not as a cudgel, but as a gift. The two events belong to one story. To read the eight catecheses well is to understand precisely what the men at Écône walked away from.
A reform rooted in the living tradition
Begin where Leo ended, because the last catechesis is the key that turns the whole lock. The reform of the liturgy, he insisted in his concluding reflection, is “firmly rooted in the living tradition of the Church.” This was no throwaway line. He built it, brick by brick, from the history the traditionalist narrative prefers to forget: the desire for a general reform, he reminded us, did not erupt suddenly in the 1960s but had been gathering since the beginning of the twentieth century, in the actions of pope after pope. Pius XI had already written, in Divini Cultus, that the faithful must not attend the sacred rites as “strangers or silent spectators.” Pius XII had restored the Holy Week liturgies to the hours of the events they commemorate, after centuries of their being anticipated in the morning. John XXIII had simplified the rubrics of the Breviary and Missal and, in the motu proprio Rubricarum instructum of 1960, had referred the very principles of a coming reform. The Missal of Saint Paul VI did not fall from the sky in rupture with what preceded it; it was the fruition of a movement three generations in the making.
And here is a truth about that movement which turns the traditionalist charge inside out. The reform is forever described by its critics as something imposed from above — a fabrication handed down by committee and decree, over the heads of a passive people. The history is precisely the reverse. The Liturgical Movement, which Leo was right to name, did not begin with a magisterial pronouncement at all. It began below: in the choir stalls and studies of monks and scholars, and in the hunger of ordinary faithful. It began with Guéranger at Solesmes recovering the Church’s chant; with Dom Lambert Beauduin at Mont-César, in Louvain, placing the missal back into the hands of the people; with Guardini and Odo Casel and Pius Parsch, and, in America, with Virgil Michel at Collegeville — men who had felt, and dared to name, the ache of a liturgy grown distant, clericalized, and desiccated, a sacred action performed at the faithful rather than by them. What these servants of the Church discerned from below, the magisterium then heard, weighed, and confirmed from above: Pius X in 1903, Pius XII in Mediator Dei, and at last the Council itself. This is the ecclesia docens, the teaching Church, stooping to listen to the ecclesia discens, the learning Church — and finding in that instinct of the faithful not a threat to tradition but tradition’s own living voice, the sensus fidelium at work. The reform was not decreed into being over the heads of the people. It was discerned among them and ratified by their shepherds. Those who now denounce it as an imposition from on high have the story exactly backward.
This is the principle Leo had laid down in his second catechesis, and to which he returned again and again: that the liturgy is a living entity, and that the Church distinguishes within it between elements “divinely instituted” and immutable and elements subject to change — elements which, in the Constitution’s bracing formula, “not only may but ought to be changed” when they have ceased to serve the mystery (SC 21). The distinction is not a modern invention; Leo traced it to Pius XII’s Mediator Dei of 1947. And to keep it from being misheard as a charter for endless mutation, he reached, in that second reflection, for Benedict XVI’s luminous image: it is a mistake to set tradition and progress against each other, for tradition is a living thing that carries the principle of its own development within itself — as a river carries its source and flows toward its outlet.
That image governs everything, and it gives this essay its title. The genius of Leo’s whole catechesis is to have refused the choice the liturgy wars insist upon — between a tradition frozen at 1962 and a progress cut loose from its headwaters. The reformed rite, he tells us, is neither. It is the living river of Tradition, still bearing its source. Everything else follows from this.
Not strangers or silent spectators
If the living tradition is the riverbed, participatio actuosa is the current. And the final catechesis performed a genuine act of disclosure: it revealed that the full, conscious, and active participation of the faithful was not one aim of the reform among many but its very motive. Leo reached back to a letter the future Paul VI, then Archbishop Montini of Milan, wrote to his people in October of 1962 — before the Council had promulgated a single line. The liturgy, Montini had written, is a language, a voice in dialogue with God, and for that reason the faithful “cannot and must no longer remain silent and passive”; their physical presence, he said, “cannot be reconciled with their spiritual absence.” A year later the Council would enshrine the same conviction in the words that became the leitmotif of Leo’s entire series: the faithful should not be present at the mystery “as strangers or silent spectators,” but should take part “conscious of what they are doing,” offering the Immaculate Victim “not only through the hands of the priest, but also with him,” and so learning to offer themselves (SC 48).
Follow that phrase — strangers or silent spectators — and you have the spine of the whole catechesis. It surfaced first in the third reflection, on rite, sign, and symbol, where Leo insisted that the rites are not “a mere external covering” of the mystery but the ecclesial mediation through which the divine gift actually reaches us — so that the whole person, body and soul, must be drawn in. It returned in the fifth, on the prayer of the Church, where he named active participation, in so many words, as the “central pillar” of the reform. It came again in the sixth, on the liturgical year, where he gave it its sharpest contemporary edge: the Sunday assembly, he said, “cannot be substituted by a solely virtual presence, nor be reduced to a merely passive gathering” — the screen and the spectator named as the two great erosions of the Lord’s Day. And it reached its fullest statement in the seventh, on sacred music, where the singing of the whole assembly became the very image of a participation that is neither performance nor passivity.
What the final catechesis added was the revelation that this was there from the beginning — in Montini’s letter, in Pius XI, in the Liturgical Movement itself. The reform did not invent active participation; it was called into being by it. And so the tiresome caricature — that participatio actuosa is a modern intrusion, a Protestant busyness imposed on a contemplative rite — collapses under the weight of its own history. Leo has shown that the principle is older than the reform it produced.
The sacrament of unity
Beneath the current runs a still deeper theme, and it is the one that bears most directly on the sorrow of this summer. The liturgy is the Church’s act of communion, and it is never a private possession. Leo returned to this from the first, when in his opening catechesis he refused to treat Sacrosanctum Concilium as ammunition in the liturgy wars and instead restored it to its proper genre — catechesis on the mystery of Christ, the place where the Church “receives her very life” from her Lord. He deepened it in the fourth reflection, on the Eucharist, where, through Augustine’s sermon to the newly baptized, he taught that in receiving the Body of Christ the Church becomes what she receives — and named the Eucharist, with the Constitution, “a sign of unity, a bond of charity,” the antidote to the forces of division that wound our communities, our families, our hearts. He gave it perhaps its loveliest form in the catechesis on sacred music, where song became “an epiphany of the Church, a tangible manifestation of the communion that belongs to her very nature,” and where he closed with Ignatius of Antioch begging the Ephesians to become a choir and sing “with one voice.”
And in the last reflection he stated the principle at its root, quoting the Constitution directly: liturgical services “are not private functions, but are celebrations of the Church, which is the ‘sacrament of unity’” (SC 26). This is the thread the whole series makes foundational, and it is the exact point on which the tragedy of Écône turns. What the Society’s act severs is not a liturgical preference — the Church has shown herself endlessly patient with preference. It severs the one thing these eight catecheses make indispensable from first to last: communion as the very condition of authentic liturgical life. A Eucharist offered against the visible communion of the Church contradicts the thing the Eucharist most deeply is. You cannot claim the river of Tradition while stepping out of its channel.
It was in the seventh catechesis, fittingly, that Leo named the ancient axiom that ties all of this together — lex orandi, lex credendi, the law of prayer is the law of belief — and added that it must “remain alive and continue to grow.” How the Church prays is how the Church believes, and how she believes shapes how she must live. To touch the one is to touch the others. This is why the present rupture is doctrinal and not merely ceremonial, and why Leo’s patient, unpolemical teaching on prayer was never as far from the meadow at Écône as it seemed.
Both flanks, in his own voice
For two generations, a certain kind of Catholic has insisted that Rome could only ever discipline one side of the liturgical divide. The final catechesis put that suspicion to rest, because Leo corrected both flanks in the same breath, and did so in his own voice. The reform, he said, is rooted in the living tradition — and precisely “a correct understanding of it also enables us to reject the abuses that occurred in certain sectors of the Church during the post-conciliar period, and which, unfortunately, still occur from time to time today,” wherever the reform’s own principles “have been taken to extremes or misunderstood.” Here is the balanced hermeneutic stated from the Chair of Peter: the reform is legitimate and its distortions are to be repudiated. The liturgical narcissism of the do-it-yourself celebrant offends against the Council as gravely as the reactionary’s refusal of it — and Leo, invoking the Constitution’s insistence that no one, “even if he be a priest,” may alter the liturgy on his own authority (SC 22), let neither party imagine the correction was meant only for the other.
The same even-handedness runs through the whole series in a subtler form, and it is worth naming because it is the heart of Leo’s pastoral genius. Over and over, he received the patrimony whole rather than conceding it to one camp. He opened his catechesis on the liturgical year by honoring Dom Prosper Guéranger, the Abbot of Solesmes whom the traditionalist world holds dear. He built his teaching on sacred music upon Pius X’s motu proprio of 1903, gave Gregorian chant its “great value” and the organ its honored place — and then bent that entire inheritance toward the singing of the assembly, establishing the reform’s central principle out of the mouths of the very popes the traditionalists most revere: Pius X, Benedict XVI, John Paul II. He is not fighting them for the treasure. He is showing them that the treasure was always ordered to the participation they resist.
And where the abstract principle of tradition-and-development needed a concrete instance, Leo simply held one up. To the charge that the reform ruptured continuity, his answer in the fourth catechesis was not an argument but a concrete example: the enriched Lectionary, which opened the treasures of Scripture more abundantly to the faithful and which he named as itself drawn from the living Tradition, uniting fidelity with legitimate progress. Open the book, he all but said, and read from a richer table than any generation before you was given. The reform is not the rupture of Tradition. It is Tradition, doing in our age what it has always done.
What it means for Écône — and for the rest of us
Read together, then, these eight reflections give an unusually clear sightline into how this pope understands the liturgy, and therefore into how he is likely to govern the reconciliation that still, even now, awaits a resolution. His mind is thoroughly conciliar: the reformed rite is the Church’s normative lex orandi — organically developed, ecclesially owned, ordered to the active participation of all the faithful, consummated in the Eucharist that makes the Church one. That is the fixed point, and no one who listened to this catechesis can feign surprise at it. Yet the very principles that establish the reformed rite as normative also furnish the grammar of charity toward those still attached to the preconciliar rite: organic continuity rather than rupture, always giving the benefit of the doubt rather than suspicion, communion as the criterion of every legitimate accommodation. A pope who teaches that the liturgy is the sacrament of unity is laying the groundwork for an accommodation offered cum Petro et sub Petro — with Peter and under Peter — never against him. The door he has been holding open is real. But it is a door that opens only inward, toward Peter; it has never opened the other way, and it cannot, because a liturgy set against the Church’s communion has already contradicted itself.
I do not think it a coincidence of the calendar that the first of these catecheses were delivered in the weeks before the consecrations, and that Leo took the series up again the moment the summer was drawing to a close — the same Constitution, the same chair, not a word of retraction. The witness was declined at Écône. It was not withdrawn. It remains on offer to all who would receive it. And it was completed, this past week, not with a lament over the schism but with a pastor’s charge: that bishops and priests safeguard a liturgy which, “respecting liturgical norms,” shines with the “noble simplicity” the Council desired (SC 34) and so manifests the one, holy, catholic, and apostolic Church — a liturgy that is itself, he said, a fundamental vehicle of evangelization.
Those of us who have spent our lives in the service of the Church’s worship have waited a long time to hear a pope lay it out so completely and so calmly: that the reform is neither the betrayal its enemies allege nor the license its abusers assume, but the living tradition of the Church, drawing the whole People of God into the mystery of Christ. The river continues to flow. It carries its source within it. And this pope, I have no doubt, will keep teaching us to drink from it — to the end of the Council’s documents and past them — until those who have stepped out of the current are ready to return to the bank where he is still standing, with the water moving past.
