Church of the Priestly Fraternity of Saint Pius X in São Paulo: traditionalist congregation prays masses in Latin. BBC As usual, the solemn mass dedicated to Saint Peter and Saint Paul was celebrated in Latin in Saint Peter's Basilica, in the Vatican, on the 29th. Three days later, Pope Leo would excommunicate the leaders of the ultraconservative group Priestly Fraternity Saint Pius X, which has among its banners precisely the celebration in the old language. However, anyone who thinks it is the same thing is mistaken. In the liturgical aspect, the problem is not in the language, but in the rite practiced and the entire political-ideological aspect of this decision. ? Follow the g1 international news channel on WhatsApp The now excommunicated Brotherhood was not punished for its predilection for the old-fashioned language. She was punished for disrespecting papal authority and for insisting on denying the decisions of the Second Vatican Council, a series of meetings held by the Catholic leadership between 1962 and 1965 with the aim of modernizing the Catholic Church. The tip of the iceberg of this movement is in the group's celebrations, in the way before the council, that is, following the so-called Tridentine rite. Historian and religious scientist Víctor Gama, researcher at the Pontifical Catholic University of Minas Gerais (PUC-MG), recalls that among all the differences that the Fraternity has with the contemporary Catholic Church, the "most visible" is the liturgical issue. "They understand that the 'old Mass,' the Tridentine Mass, is the most perfect expression of Catholic worship." This ancient mass format is always in Latin and with the priest with his back to the assembly. The model approved at the council and adopted by the Western Church after it does not prohibit the Latin language, nor does it restrict the way in which the priest must position himself before the faithful. However, in the name of greater accessibility and ease of communication, he suggests that masses be in the community's vernacular language and that the priest should address the people, optimizing understanding. Latin, as the official language of the Vatican, present in numerous official documents, can be used, especially on solemn occasions. But even so, as occurred in the recent mass dedicated to Saint Peter and Saint Paul, the liturgical and contemporary rite and, for everyone to understand, both the biblical readings and the celebrant's homily, are done in the community's current language. Pope Leo "The Second Vatican Council did not ban Latin, but it facilitated the use of local languages", summarizes theologian and historian Gerson Leite de Moraes, professor at Universidade Presbiteriana Mackenzie. "The orientation was that the mass should become more inclusive."

This is one of those parish legends that were repeated by people who never read half a page of the Council", comments Father José Eduardo de Oliveira e Silva, doctor in theology from the Pontifical University of Santa Cruz, in Rome. "The Code of Canon Law says that the Eucharistic celebration can be done in Latin or in another language, as long as the texts are legitimately approved. And the Second Vatican itself said that the use of Latin should be preserved in Latin rites, although it admitted a wider use of the vernacular language when this was pastorally useful." "So, in a common parish, in the current Roman rite, the priest can celebrate in Latin", adds the priest. "What he cannot do is invent a particular liturgy, make the Mass a personal manifesto or use Latin as a battle flag against the Church itself." The Tridentine rite, used by followers of the Saint Pius Fraternity, refers to the Council of Trent, held between 1545 and 1563. It turns out that, at that time of more difficult communication, the masses ended up being different from each other. "There was a tendency for the liturgy to develop differently in each place. After Trent, we sought to unify this", he points out. It was necessary to standardize. One of the issues debated in that series of Church meetings was precisely the desire to create a rite that unified the celebrations. Hence the rite, which ended up being the practice in Catholic parishes in the West until the Second Vatican Council. The format ended up being popularly known as "Latin Mass" or "Old Mass". With the priest's back turned. In fact, the idea was that the priest would also be facing the altar, as well as the assembly — in that format, in a language that few spoke, it was actually difficult to predict an interaction between the priest and the faithful. Over the centuries, this liturgy underwent updates. The last text of this type of celebration is in the 1962 Roman Missal, precisely the one that is usually used by those who deny the advances of the council held in the 1960s. Pope Leo obsolete missal — the "so-called liturgical form prior to the post-conciliar reform", as Father Oliveira e Silva defines it — is. "The expression 'mass in Latin' was a way of simplifying a much more complex issue", says Domingues. The issue, he contextualizes, involves the so-called traditionalist movement of the Church, a series of conservative groups that emphasize the pre-conciliar period — and, to a greater or lesser extent, do not accept the decisions of the Second Vatican Council. Concerned about the advance of ultra-conservative traditionalist groups, Pope Francis (1936-2025) published a document in 2021, called Traditionis Custodes, determining that such celebrations can only take place with authorization from the bishop responsible for the circumscription. "Based on this document, this Tridentine Mass can only be celebrated in some specific situations. Francis stated that the 2nd Vatican Council had already decided on a single form of celebration, so what could be done was for the Church to make exceptions for some communities, for pastoral reasons", explains Vaticanist Domingues. "The document also demands that groups linked to this liturgy do not deny the validity and legitimacy of the liturgical reform, the Second Vatican and the magisterium of the popes", highlights Oliveira e Silva. The idea was to curb schisms and maintain unity, while pastorally respecting options outside the contemporary script. "Francisco established some criteria for this. One of them is that new traditionalist groups should not be created, as the Tridentine mass could only be granted to existing groups", points out Gama. "It also could not be celebrated in parish churches, but only in chapels." Previously, Pope Benedict XVI (1927-2022) had facilitated the rite of the "old mass". "He granted universal authorization, a document, in 2007, which said that any priest could decide to celebrate in this rite, without needing to ask for authorization", says Gama. "There was universal freedom and it was a moment of growth for the Tridentine Mass in Brazil and the world." On his back Regarding the position of the celebrant priest, Oliveira e Silva clarifies that the technically correct expression is not the popular "on his back", but rather the Latin form ad orientem. "In the old rite, this is normal. In the new rite, the celebration aimed at the people became the ordinary practice", he comments. According to the General Instruction of the Roman Mission, the altar must be built so that it can be celebrated facing the people. "It is considered desirable wherever possible", emphasizes the priest. "But the physical direction of the celebrant is not an automatic detector of faith", highlights Oliveira e Silva. "God doesn't fit into this sacristy geometry." "This way of celebrating has not been abolished", highlights Gama. "But it ended up falling into disuse, because the liturgy underwent a series of reforms with the aim of becoming more adapted, of becoming more understandable for our time." In the understanding of traditionalists, the importance of Latin can be understood under several layers. Firstly because the language functions as a historical sign. "It's continuity, universality and stability", says Oliveira e Silva. "It does not belong to a nation. It creates a kind of sacred distance in relation to the banal use of language. And because it is a stable language, it helps to protect doctrinal formulas from oscillations, fads and unfortunate translations." Domingues recalls that when the contemporary rite uses Latin, it generally does so to emphasize the "dimension of the universality of the Church". "It is also used as the official language of the Holy See", he highlights. There is the symbolic aspect. "Latin links the Roman liturgy to centuries of prayer, Gregorian chant, theology, canon law, saints, councils, pontifical documents", lists Oliveira e Silva. "Reminds the faithful that the Church did not begin yesterday." "Latin has the character of universality and also the characteristic of immutability, as it is a dead language", analyzes Gama. He emphasizes that there is still the theological aspect, as the Catholic Church recommends that its priests understand the language well. The problem, reminds the priest, is in the caricature. "It's thinking that Latin, in itself, is the criterion. That's ideology", he comments. "Latin can be used holy, as a language of prayer in the Church. Or it can become an aesthetic fetish." For theologian Moraes, this emphasis on the use of Latin refers to a period in which the Catholic Church held hegemonic power in Europe. In a way, traditionalist groups want to recover this aura, in a perspective that denies contemporary, secularized society itself, according to the professor's analysis. The current schism In the case of the Society of Saint Pius X, the Tridentine Mass is just the outer shell of a much deeper problem. "The fundamental question is ecclesiological: who has the authority to authentically judge tradition", comments Father Oliveira e Silva. "The problem is not the Latin Mass, the rite. It's that people are doing it because of a political, ideological and doctrinal issue", says Domingues.
