Reassessing the Roman Mass: Tradition vs. Liturgical Reform

An international conference at KU Leuven has reopened questions which defenders of the postconciliar liturgical reform have too often presumed settled. For Traditional Catholics, the issue is not whether the ancient Roman Mass deserves accommodation within the contemporary Church, but whether its extensive reconstruction can be reconciled with the Church’s obligation to preserve and transmit her received worship. The Roman liturgy is not a pastoral experiment, nor is Tradition whatever the latest ecclesiastical legislation permits. It is an inheritance expressing the Church’s unchanging Faith. The reform must therefore be judged against that inheritance, not the inheritance against the reform.

For more than sixty years, Traditional Catholics have been expected to defend their attachment to the Roman Mass which nourished the Church for centuries. They have been asked to justify its Latin, its silence, its sacrificial prayers, its sacred gestures, its eastward orientation and its unmistakable distinction between the ministerial priesthood and the participation of the faithful. They have been accused of confusing reverence with nostalgia, historical continuity with resistance to authority, and fidelity to inherited worship with opposition to the Church herself. Yet the question requiring an answer is not why Catholics remain attached to the liturgy which formed generations of saints. It is why that liturgy was subjected to such extensive reconstruction, upon what theological principles the changes were justified, and whether the resulting rite preserved the fullness of the inheritance it displaced. That is the question which ought to govern consideration of the international conference being held at KU Leuven on 22–23 October 2026.¹

Entitled Tradition and Reform in the Roman Rite: The Usus Antiquior in Contemporary Catholicism, the conference brings together nine keynote speakers and other scholars examining the historical, theological, sociological and canonical consequences of the postconciliar liturgical settlement. Its programme includes serious enquiries into the sacrificial theology of the Mass, the nature of active participation, the relationship between the Council and its implementation, the attraction of the ancient rite among younger Catholics, and the juridical restrictions imposed by Traditionis Custodes. The gathering was preceded by a traditional Mass of the Holy Ghost on 21 October, scheduled to be celebrated by Mgr Roger Gryson with Gregorian chant and the permission of Archbishop Luc Terlinden. That detail illustrates the present ecclesiastical circumstances: the inherited Roman Mass remains a legitimate object of theological enquiry, even as its celebration has become subject to exceptional restrictions. The conference is not a Traditionalist assembly, and its speakers do not share a single interpretation of the reform. Nevertheless, their enquiries challenge the assumption that papal promulgation has settled every historical and theological controversy surrounding the reconstruction of Roman worship.¹

A properly Traditional Catholic assessment begins from a principle frequently obscured in contemporary liturgical discussion: the Roman liturgy is not primarily a pastoral instrument devised by ecclesiastical authority to satisfy the requirements of successive historical periods. It is the Church’s received public worship, progressively enriched through centuries of doctrinal clarification, spiritual experience and sacred practice. Its fundamental purpose is the glorification of Almighty God, above all through the Holy Sacrifice of the Mass, rather than the production of a particular kind of congregational experience. Its pastoral efficacy proceeds from its fidelity to that supernatural purpose. The faithful are formed by entering into the Church’s worship; the Church’s worship is not to be continually reconstructed according to the changing expectations of the faithful.

This principle does not deny legitimate liturgical development. The Church has always regulated her rites, corrected abuses, clarified ceremonial prescriptions and authorised appropriate alterations. Nor does it imply that every historical custom possesses the authority of a divinely instituted element of the sacraments. Nevertheless, the Traditionalist understanding distinguishes organic development from comprehensive reconstruction. The former receives an existing tradition and develops it according to its own internal principles. The latter examines inherited worship as material available for rearrangement according to a programme conceived by the reformer. Both may be undertaken under competent ecclesiastical authority, but they are not therefore historically or theologically equivalent. The possession of authority to introduce a change does not establish that the change constitutes organic development, that it was necessary, or that it improved what preceded it.

This distinction was already implicit in the liturgical settlement of St Pius V. His promulgation of the Roman Missal in 1570 sought to preserve and standardise the received Roman tradition against confusion and unauthorised innovation. His legislation respected sufficiently ancient established usages rather than requiring their universal replacement. Quo Primum must not be misrepresented as rendering every subsequent alteration juridically impossible; the Roman Pontiff retained legitimate authority over the Church’s liturgical discipline. Its historical significance lies instead in the conception of authority which it exemplified: the Pope as guardian and regulator of inherited worship, not the proprietor of a religious system available for comprehensive redesign. The traditional Roman liturgy preceded the legislation which codified it, just as its theological character preceded the twentieth-century legislation which subsequently restricted its use.²

The same understanding informs Pius XII’s Mediator Dei. The encyclical acknowledges the Holy See’s authority to modify liturgical rites, but also condemns the false antiquarianism which assumes that an earlier form is necessarily superior merely because it is older. Inherited prayers and ceremonies are not disposable accretions obscuring an imagined primitive purity. They frequently embody developments through which the Church has come to express her understanding of the mysteries more fully. The traditional Offertory, the Roman Canon, the ceremonial surrounding the Consecration, the liturgical year and the inherited Office constitute an integrated tradition of prayer and belief, whose accumulated significance cannot adequately be assessed by asking whether individual elements might be omitted without affecting sacramental validity.³

This is the importance of lex orandi, lex credendi. The Church’s prayer expresses her belief, but it also forms successive generations in that belief. Liturgical texts and ceremonies are not neutral containers into which doctrinal propositions may be poured without consequence for their meaning or reception. Kneeling before the Blessed Sacrament teaches adoration. The genuflections and joined canonical fingers of the celebrant express reverence for the Real Presence. The traditional Offertory directs attention towards the Sacrifice about to be accomplished. The silent Canon places the faithful before an action whose supernatural significance exceeds ordinary human speech. These things do not constitute separate dogmas, and their omission does not necessarily entail formal denial of doctrine. Together, however, they establish a consistent sacramental grammar. Altering that grammar changes the manner in which Catholic belief is encountered, understood and transmitted.

It is here that the contribution of Fr Sven Leo Conrad FSSP becomes especially significant. His paper distinguishes the inherited Roman rite, whose developed structure presents worship as actio sacra, from the postconciliar rite, whose outward form places greater emphasis upon the visible gathering of the local community. Conrad states: “Mit der Änderung der Formalstruktur ist die Theozentrik der Liturgie betroffen” — with the change in the liturgy’s formal structure, its God-centred character is affected. His argument concerns the theological meaning of liturgical form itself, not merely variations in language, ceremony or aesthetic preference. He identifies a change of paradigm and proposes to examine its ecclesiological consequences, including the relationship of the reformed rite to the sacrificial doctrine of Trent. Conrad does not simply dismiss the newer rite; his abstract also considers possibilities of mutual enrichment. Nevertheless, his analysis identifies precisely the theological difficulty which Traditionalists have long regarded as decisive. The controversy concerns whether the liturgical action continues to express with equal clarity the objective offering of Christ’s Sacrifice to Almighty God, or whether its reconstructed form increasingly directs attention towards the assembly celebrating it.⁴

The traditional Roman Mass possesses an unmistakably sacerdotal character. Its priest does not appear principally as the presiding officer of a religious assembly but as the minister of Christ’s Sacrifice. His prayers, gestures, orientation and ceremonial obligations direct him towards the altar and the sacred mystery entrusted to his hands. The faithful participate through their union with that offering, but the efficacy of the Mass does not depend upon their collective activity or even their physical presence. The priest celebrates according to a received rite whose authority precedes the particular congregation and whose essential purpose remains unchanged whether the church is crowded or empty. This objective conception of worship is central to Traditional Catholic theology. The Mass is offered first to Almighty God; its fruits for the faithful proceed from the Sacrifice rather than from the success of a communal religious event.

The postconciliar reform altered the manner in which this relationship is ordinarily perceived. The multiplication of spoken dialogue, the widespread adoption of celebration facing the people, the reduction of sacerdotal gestures, the replacement of the ancient Offertory prayers and the expansion of congregational functions collectively established a different external emphasis. Not every feature was commanded by Vatican II, and some became widespread through pastoral custom rather than universal legal requirement. Moreover, the reformed Missal retains the doctrine of the Eucharistic Sacrifice, the Real Presence and the essential distinction of the ordained priesthood. The Traditionalist criticism is therefore not that a properly celebrated reformed Mass cannot be valid. It can. The criticism is that the reform diminished the inherited rite’s consistent sacrificial expression by reorganising its ceremonial structure around considerations of visibility, accessibility and communal participation. A valid rite may accomplish the sacramental action while communicating its surrounding theology with less clarity than its predecessor.

Dr Angela Costley’s examination of the Old Testament sacrifices prefiguring the Mass brings this question back to the doctrinal foundations established by the Council of Trent. The inherited Roman prayers situate the Eucharistic Sacrifice within the continuity of biblical sacrifice, priestly mediation, oblation and propitiation. Michael P. Foley’s accompanying paper on the Offertory examines the differences between the traditional and reformed rites with particular attention to the sacrificial meaning of the prayers. The traditional Suscipe, sancte Pater and Offerimus tibi, Domine anticipate the Eucharistic Sacrifice through explicitly oblationary language. The revised preparation of the gifts employs a different textual structure. It is insufficient to observe that orthodox sacrificial doctrine survives elsewhere in the new Missal and conclude that nothing of theological significance has changed. The doctrine may remain officially affirmed while its cumulative ritual expression is diminished. The Church did not develop her sacrificial prayers over centuries merely to furnish material for later commissions to abbreviate or replace according to changing conceptions of pastoral intelligibility.⁵

The relationship between ritual expression and Eucharistic belief consequently deserves particular scrutiny. The decline in sacramental confession, weakened consciousness of mortal sin, casual approaches to Holy Communion and diminished understanding of the Real Presence are serious pastoral concerns. But the evidence does not permit the simple conclusion that liturgical reconstruction directly caused these developments. Secularisation, defective catechesis, changing family structures and failures of ecclesiastical leadership all require consideration, and the prevalence of Eucharistic disbelief cannot be established merely by observing differences in ceremonial practice. The Traditionalist criticism is more precise: the inherited liturgy possessed a dense and coherent structure of ritual signs reinforcing the distinction between sacred and profane, the sacrificial nature of the Mass and the necessity of reverence before the Real Presence. The systematic reduction of those signs removed a significant means of religious formation. Whether, and to what extent, that removal contributed to subsequent losses of Eucharistic understanding is an empirical question deserving investigation. That the changes altered the theological expression and formative character of worship is already a legitimate matter of liturgical analysis. Neither sacramental validity nor the personal devotion of Catholics attending the reformed Mass renders that question irrelevant.

Fr Uwe Michael Lang’s contribution supplies the historical and ecclesiological framework for this enquiry. Drawing upon Joseph Ratzinger’s reflections, he distinguishes the theological principles expressed by Sacrosanctum Concilium from the practical decisions made in their subsequent implementation. As Lang observes, many of the Constitution’s concrete proposals “belong to the realm of pastoral and disciplinary application”, and may therefore legitimately be reconsidered. His approach does not reject the Council’s authority. Rather, it insists upon distinguishing the Council’s teaching from the particular programme subsequently undertaken in its name. Vatican II called for reform, simplification, intelligibility and fuller participation. It did not command the replacement of the traditional Offertory, the introduction of alternative Eucharistic Prayers, the widespread abandonment of Latin or the almost universal adoption of celebration facing the congregation. Those developments were decisions of the reforming authorities, subsequently sanctioned through papal jurisdiction. Their legality does not demonstrate that they were demanded by the Council, nor that they satisfied its requirement of organic continuity.⁶

Indeed, Sacrosanctum Concilium itself established the standard against which its implementation must be judged. Paragraph 23 required that there be no innovations unless the Church’s genuine and certain good demanded them, and that new forms should develop organically from those already existing. Pope Leo XIV repeated this principle in his General Audience of 27 May 2026, quoting the Council’s requirement that new forms “grow organically from forms already existing”. His address defended the postconciliar reform, rather than repudiating it, but it also reaffirmed the criteria by which any liturgical development must be assessed. The difficulty is not identifying those criteria. It is demonstrating that the particular alterations introduced after the Council consistently fulfilled them. Nuntiatoria has previously made this distinction in The Council, the Reform, and the Missing “Thus” and The Reform Before the Reform. The history of the reform cannot be rewritten by treating the Council’s authorisation, the decisions of the Consilium and the practices subsequently normalised as though they constituted a single legislative and theological act.⁷

The prehistory of the Missal of Paul VI is particularly revealing. Between 1964 and 1969, priests were progressively instructed to celebrate the Roman Mass differently. The Canon could be proclaimed aloud, vernacular use expanded, ceremonial gestures were reduced, and the obligation to keep thumb and forefinger joined after the Consecration disappeared. Altars were increasingly arranged for celebration facing the people, although neither the Council nor the revised Missal made this universal practice obligatory. Each alteration could be defended separately as simplification, clarification or pastoral adaptation. Yet the accumulated effect was to form a different understanding of liturgical action. A priest trained to conform himself meticulously to an inherited ceremonial was increasingly instructed to regard elements of that ceremonial as dispensable or subject to practical reassessment. The transformation was not merely textual. It was pedagogical and spiritual, changing how priests were taught to approach the Church’s ritual inheritance.³

The distinction between sacred and ordinary language reveals the same underlying problem. Professor Tracey Rowland’s contribution contrasts John XXIII’s defence of Latin in Veterum Sapientia with Paul VI’s greater emphasis upon vernacular intelligibility and Benedict XVI’s insistence upon beauty in the sacred liturgy. Her particular concern is hieratic language: language reserved for sacred purposes, distinguished from ordinary communication precisely because worship is not ordinary communication. Latin preserved doctrinal formulations, expressed catholicity across national boundaries and marked the transcendent character of Roman worship. Its value did not depend upon the congregation’s ignorance, nor did its retention prohibit catechesis or comprehension. Traditionalists reject the assumption that immediate verbal intelligibility must govern the form of divine worship. The Holy Mass is not a lecture, and its prayers do more than convey information. The sacred mysteries demand explanation because they transcend ordinary experience; they do not cease to be mysteries because their language is translated.⁸

A related misunderstanding concerns actuosa participatio, examined at Leuven by Dr Nathaniel Marx. The twentieth-century promotion of active participation was not intrinsically contrary to Tradition. St Pius X and Pius XII encouraged the faithful to participate consciously and fruitfully in the Church’s worship. The difficulty arose when participation increasingly came to be assessed through visible congregational activity. The traditional Roman understanding begins elsewhere. The faithful participate through baptismal union with Christ, interior association with His Sacrifice, prayer, adoration, contrition and thanksgiving. A person kneeling silently at Low Mass may participate more fruitfully than another performing a conspicuous liturgical function. Equally, silence does not automatically establish interior recollection. The fundamental distinction is between spiritual participation and the mere multiplication of liturgical activity. Marx’s abstract indicates that traditional Catholics commonly value the stability of external forms precisely because they encourage interior participation. This does not exclude congregational chant or appropriate responses; it restores those practices to their proper theological order.⁹

That distinction becomes especially relevant in the light of Cardinal Grzegorz Ryś’s remarks on 17 October at the inauguration of Kraków’s School of the Council. Recalling his participation in a twelve-member group examining the conciliar liturgical reform for Pope Leo XIV, Ryś declared, in translation, that the reform had not been accomplished. He explained that the vernacular and altars facing the people constituted only preliminary conditions; the essential objective was the active participation of all the faithful. Yet this explanation demands precisely the distinction explored at Leuven. If active participation means the conscious and fruitful union of the faithful with Christ’s Sacrifice, that objective was recognised long before Vatican II. If its fulfilment is assessed principally through the visible distribution of liturgical responsibilities, participation risks becoming an organisational ideal rather than a supernatural reality. More fundamentally, after six decades of revision, experimentation and pastoral adaptation, the continuing claim that the reform remains unfinished raises an unavoidable question: whether its governing assumptions are themselves adequate to the spiritual problem they were intended to remedy.¹⁰

Professor Luc Perrin’s historical paper introduces an indispensable corrective to the tendency to identify the whole ancient Roman tradition with the books of 1962. Perrin examines the evolution of traditionalist resistance and acknowledges that not every current of attachment to the inherited liturgy accepted the successive reforms of Pius XII and John XXIII without reservation. The 1962 Missal already incorporated significant twentieth-century revisions, including the reconstructed Holy Week. The Roman Breviary before Divino Afflatu possessed a different arrangement of the Psalter and Office, while the earlier Roman liturgical year retained structures altered by later reforms. These distinctions concern the very question of how organic development is distinguished from deliberate reconstruction. The 1962 books became the practical standard for particular traditionalist movements and subsequent Roman legislative settlements, but their juridical selection did not make them the exclusive measure of the ancient Roman inheritance. Serious enquiry must examine the continuity of the rite across its history, including the changes which preceded the Council.¹¹

The sociological contributions challenge another assumption underlying the postconciliar settlement: that inherited forms of worship are necessarily less capable of engaging contemporary Catholics. Dr Rowena Roppelt examines the attraction of the ancient Mass among young Catholics in Munich, while Dr Stephen Cranney investigates the relationship between demanding religious communities and their apparent vitality. Such studies must be interpreted carefully. They cannot establish that all traditional parishes are flourishing or that the entire decline of Western Catholicism can be attributed to the liturgical reform. Yet they challenge the explanation that attachment to the traditional Mass is primarily nostalgic. Young Catholics who have no personal memory of the preconciliar Church are finding religious meaning in precisely those features which reformers frequently regarded as pastoral obstacles: sacred language, ritual discipline, silence, stability and an unmistakable supernatural orientation. What was once judged difficult for modern man may be experienced by his descendants as an antidote to the spiritual impoverishment of modernity.¹²

Dr Clara E. Piano’s research into traditional parishes and Catholic family formation provides a more concrete pastoral consideration. Her conference programme reports that identified traditional Latin Mass locations in the United States increased from 200 in 2005 to 513 in 2020. Using diocesan data, her preliminary analysis associates the presence of the traditional Mass with approximately 0.15 additional Catholic marriages and 1.1 additional infant baptisms per thousand Catholics, alongside a reduction in interfaith marriages. The total number of marriages remains essentially unchanged, and the observational findings do not establish that traditional liturgy directly caused these differences. Nevertheless, the results are consistent with the proposition that traditional communities provide an environment in which Catholics seeking marriage can identify prospective spouses committed to the Church’s moral teaching and sacramental life. Their significance cannot be reduced to demographic productivity. They suggest that the preservation of distinctive Catholic worship may assist the formation of coherent Catholic communities capable of transmitting belief, discipline and family life between generations.¹³

Here the Traditionalist criticism of modern Catholic pastoralism becomes unavoidable. For decades, adaptation to contemporary society has frequently been presented as an indispensable condition of evangelisation. The Church must speak the language of modern man, accommodate his sensibilities, minimise unnecessary distinctions between sacred and ordinary life, and make religious participation more accessible. Yet many traditional communities draw their strength precisely from refusing to dissolve Catholic identity into the surrounding culture. They preserve distinctive religious practices, expect serious doctrinal commitment, maintain demanding moral disciplines and present worship as an encounter with objective supernatural realities. Their witness is not necessarily strengthened by resemblance to secular society. It may be strengthened by the visible contradiction between the claims of Catholic revelation and the assumptions of the modern world.

Traditionalists therefore see the liturgical controversy as inseparable from the wider crisis of Modernism and religious naturalism. This does not mean that every advocate of the reformed Missal personally adheres to the theological errors condemned by St Pius X, nor that every pastoral adaptation constitutes Modernism. Such accusations require precision. The deeper concern is an ecclesiastical mentality in which supernatural realities are increasingly interpreted through the categories of human experience, community formation, accessibility and contemporary relevance. When these become the controlling criteria of reform, the order of theological judgement is reversed. Instead of asking how the Church’s inherited worship most faithfully expresses the divine mysteries, reformers ask how worship may be reconstructed to accommodate the expectations of contemporary society. Tradition must then justify itself before modernity, while modernity’s assumptions are insufficiently subjected to theological scrutiny.

This is why the Leuven conference must also be considered in the context of Cardinal Arthur Roche’s recent interview concerning the traditional Roman Mass. The Prefect of the Dicastery for Divine Worship warned that rejection of the Council could lead Catholics away from the centre of the Church. As he put it: “If you reject that, if you resist it, you are edging yourself away from the centre of Catholicism.” The gravity of rejecting authentic conciliar teaching should not be minimised. But the theological distinction between a Council’s teaching and the prudential decisions adopted in its name is equally indispensable. To criticise the replacement of the traditional Offertory, the reconstruction of the liturgical calendar, the multiplication of Eucharistic Prayers or the marginalisation of Latin is not, simply by that fact, to reject the Roman Pontiff or deny the Church’s authority over liturgical discipline. As Nuntiatoria previously argued, the reform cannot become the rule by which fidelity to the Faith itself is measured.¹⁴

That distinction is essential for Catholics who recognise papal primacy and the divine constitution of the Church while maintaining that the postconciliar liturgical reconstruction constitutes a serious departure from received Roman Tradition. The Traditionalist case does not require an ecclesiology in which private judgement supersedes the Church. It requires the proper Catholic distinction between the authority of an office and the wisdom of every exercise of that authority. A Pope may possess the jurisdiction necessary to promulgate disciplinary legislation without thereby rendering every prudential determination immune from historical and theological criticism. Legitimate authority exists to safeguard the deposit of Faith, preserve sacramental life and govern the faithful towards salvation. It is not an autonomous power to make a contested historical judgement irreformable simply because that judgement informed an act of legislation.

The canonical contributions at Leuven therefore address only part of the controversy. James Bradley examines the regulations governing the ancient liturgy, while Niels Maris considers whether the faithful possess an enforceable right to its celebration under the present Code. These are necessary questions, and their answers cannot responsibly be supplied by wishful thinking. Maris’s abstract does not support an unqualified claim that every Catholic possesses a subjective canonical entitlement to demand Mass according to the 1962 Missal. Nevertheless, the deeper Traditionalist argument cannot be reduced to the existence of such a right. It concerns whether ecclesiastical government ought to restrict a liturgical inheritance whose historical continuity, theological character and spiritual fruits belong to the life of the Roman Church. The effectiveness of a restriction does not establish its prudence. Nor can legislation change the historical identity of the rite being regulated. The ancient Roman liturgy was not created by Summorum Pontificum, and its Catholic character did not disappear with Traditionis Custodes.¹⁵

The timing of Leuven gives these questions an additional significance. Pope Leo XIV has recently appointed the new members of the International Theological Commission, with reports indicating that one area of its proposed work concerns the nature, identification and transmission of Sacred Tradition. The Leuven conference is institutionally independent of that initiative, and no direct relationship between them has been established. Nevertheless, the intellectual connection is obvious. If the Church intends seriously to examine how Tradition is recognised, developed and handed on, her liturgical inheritance cannot be excluded from the enquiry. The liturgy is not identical with the deposit of revelation, but neither is it external to the transmission of that deposit. The Roman Mass embodies doctrinal truths through an established order of worship which formed generations of Catholic clergy and faithful. Its substantial alteration therefore raises questions extending beyond the immediate competence of liturgical administrators.¹⁶

The conference’s significance should not be exaggerated. Its programme includes scholars favourable to reconciliation between the liturgical forms, others concerned with historical clarification, and others critical of fundamental assumptions underlying modern liturgical reform. Their arguments are not interchangeable, and the publication of abstracts does not establish that their conclusions have been demonstrated or accepted. Nor should the conference be appropriated as though its participants had issued a collective condemnation of the Missal of Paul VI. Its importance lies rather in making serious theological enquiry possible where administrative argument has too often substituted for historical demonstration. A Church confident in the continuity of her worship should be prepared to compare the inherited and revised rites without presuming the outcome. A Church confident in her authority should not need to protect particular exercises of that authority from legitimate criticism.

A Traditional Catholic appraisal of Leuven must therefore go beyond welcoming an academic discussion of the ancient rite or seeking more generous accommodation for those attached to it. Such an outcome, however pastorally beneficial, would leave the fundamental questions unanswered. The purpose is not simply to preserve a protected enclave in which traditional Catholics may continue their religious practices while the wider Church proceeds upon substantially different liturgical assumptions. If the inherited Roman liturgy expresses the Catholic theology of sacrifice, priesthood, mediation, transcendence and adoration with a clarity diminished by its reconstruction, the consequences cannot be confined to those who personally prefer to attend it. They concern the Church’s public profession of Faith and the spiritual formation of future generations.

The traditional Roman Mass is consequently not merely an alternative spiritual resource for those who find it congenial. It is a normative historical witness to the Roman Church’s understanding of her own worship. This does not entail that every detail must remain unchanged for all time, or that the Church can never authorise other valid liturgical forms. It means that the theological content and structure of the inherited rite constitute an indispensable standard by which subsequent reforms must be judged. Continuity cannot be established by declaring the latest form authoritative and requiring the earlier tradition to conform retrospectively to it. It must be demonstrated by showing that the development genuinely proceeds from what the Church previously received.

The defenders of the postconciliar reform must therefore account for its most substantial alterations. Why were centuries of accumulated sacrificial prayers reconstructed? Why were ceremonial expressions of Eucharistic reverence reduced or discarded? Why were sacred language and silence increasingly treated as obstacles to participation? Why did a reform ostensibly governed by organic continuity produce an order of worship whose outward structure differs so markedly from the Roman Mass previously received? And why, after more than sixty years, is the reform still described by senior ecclesiastics as unaccomplished? These questions do not establish by themselves that every alteration was illegitimate or pastorally harmful. They establish that the claims made for the reform require evidence proportionate to the extent of what was changed.

Traditionalists, for their part, must substantiate their criticisms, distinguish changeable disciplinary forms from immutable doctrine, and resist the temptation to attribute every contemporary ecclesiastical failure exclusively to liturgical reform. The crisis of Catholic belief is larger than one Missal. But it would be equally mistaken to imagine that the public worship of the Church could be extensively reorganised without affecting how Catholics understand sacrifice, priesthood, grace, sin, adoration and their own relationship with Almighty God. Lex orandi, lex credendi cannot be invoked to explain the formative power of liturgy and then disregarded when considering the consequences of its reconstruction.

The Roman liturgy does not stand before the postconciliar reform seeking justification for its continued existence. The reform stands before the Roman liturgical Tradition and must account for what it changed, what it discarded and what it claimed thereby to restore. This is not a rejection of Catholic authority but an insistence upon the purpose for which that authority exists. The Church’s inherited worship is not the possession of any generation, commission, congregation or pontificate. It belongs to the Church across the centuries, whose ministers are bound to preserve and transmit the sacred mysteries entrusted to her. Legitimate authority may regulate the rites; it cannot make historical discontinuity into organic continuity merely by declaring the latter to have occurred.

Leuven will have served the Church well if it helps restore this distinction to serious theological discussion. But the Traditionalist conclusion must be stated without equivocation. The ancient Roman Mass is not simply a precious historical form deserving charitable tolerance. It is a living witness to the Church’s received Faith, against which the claims of modern liturgical reconstruction must be examined. Its continued existence is not an embarrassment to Catholic unity. It is a reminder that unity requires fidelity to an inheritance which no generation created and no generation possesses the right to treat as expendable.

The principle is apostolic. St Paul declared: Tradidi enim vobis in primis quod et accepi — “For I delivered unto you first of all, which I also received” (1 Corinthians 15:3). The Apostle speaks there of the Gospel he had received and transmitted, not of an immutable set of ceremonial rubrics. Yet the order of reception and transmission expresses the responsibility which must govern the Church’s stewardship of her sacred inheritance. She is not commissioned to manufacture a religion suited to the age, but to preserve, profess and hand on what she has received from Christ through the Apostles.

Tradition does not require rehabilitation before the tribunal of modernity. It is modernity’s interventions into Tradition which require justification.

That is the challenge which Leuven has placed once more before the contemporary Church. The reform must make its case, not merely by appealing to the authority which promulgated it, but by demonstrating its fidelity to the worship which preceded it, the doctrine which governs it and the supernatural purpose for which the Holy Sacrifice is offered.

Tradition is the measure, not the accused.
