Traditionalist Catholicism

Since the Second Vatican Council, several traditionalist organizations have been started with or have subsequently obtained approval from the Catholic Church. These organizations accept in principle the documents of the Second Vatican Council, and regard the changes associated with the Council (such as the revision of the Mass) as legitimate, if often prudentially unwise, but celebrate the older forms with the approval of the Holy See.[9]

• Priestly Fraternity of St Peter (FSSP)
• Institute of Christ the King Sovereign Priest (ICRSS, ICKSP)
• Sons of the Most Holy Redeemer (FSSR)
• Institute of the Good Shepherd (IBP)
• Servants of Jesus and Mary (Servi Jesu et Mariae, SJM)
• Canons Regular of the New Jerusalem (CRNJ)
• Canons Regular of Saint John Cantius (SJC)

• Canons Regular of the Holy Cross
• Fraternity of Saint Vincent Ferrer
• Personal Apostolic Administration of Saint John Mary Vianney (PAASJV)

There are also multiple monastic communities, including

• Monastery of Our Lady of the Annunciation of Clear Creek
• Monastery of St. Benedict in Norcia
• Monks of the Most Blessed Virgin Mary of Mount Carmel
• Monastery of Our Lady of the Cenacle
• Le Barroux Abbey

In addition, many traditionalist Catholics in good standing with Rome are served by local diocesan or religious priests who are willing and able to offer the traditional rites. Many other Catholics who sympathize with or who identify themselves as traditionalist are not able to attend the traditional liturgy regularly because it is not offered in their area (at least not with regular canonical standing) and attend the Mass of Paul VI, the current ordinary or normal[12] Roman Rite of Mass following the Second Vatican Council. Others may attend the liturgies of Eastern Catholic Churches, if they are available. There are also numerous local and international lay organizations of traditionalist Catholics, such as the youth-groups of Juventutem.

Some traditionalists receive the Sacraments from priests that are suspended a divinis by the Catholic Church, though these priests and the Catholics that attend them affirm their loyalty to the Catholic Church, while at the same time affirming that teachings of the Second Vatican Council on ecumenism, religious liberty, and collegiality are inconsistent with Catholic teaching and doctrine. They form what Julie Byrne terms the right wing of independent Catholicism: "Independents vary widely, ranging from right to left in the political spectrum. On the right traditionalist churches practice versions of Catholicism more conservative than Rome. These include the Society of St. Pius X, founded by Marcel Lefebvre, as well as the Mount St. Michael's community in Spokane, Washington, and actor Mel Gibson's church in Malibu, California, which made headlines when he directed the movie, The Passion of the Christ, in 2004.

The largest priestly society to fit this description is the Society of Saint Pius X (SSPX), which was founded in 1970, with the authorisation of the bishop of Lausanne, Geneva and Fribourg, by Archbishop Marcel Lefebvre. Members of this category view many of the post-Conciliar changes as doctrinally and pastorally unacceptable. They recognise the official Church hierarchy, while generally functioning independently of them and rejecting some decisions which they perceive as inconsistent with the Catholic faith, or ineffective in terms of catechesis and how the Catholic faith is passed down. This way of acting draws accusations of disloyalty and disobedience from many, including from members of the preceding groups that are recognised by the Holy See; on the other hand, the SSPX and groups like them consider their accusers guilty of blind obedience, which is not imposed by—and can be contrary to—the requirements of Catholic faith and morals. Discussions between the SSPX and the Holy See have been in progress for some years. In January 2009 the Prefect of the Congregation for Bishops remitted the excommunications which the Congregation had declared to have been incurred by the Society's bishops in 1988. Bishop Bernard Fellay of the Society expressed his gratitude for this act, though the Society has always held that the excommunications never took effect in the first place (citing canon 1323, §4, canon 1323, 7 and canon 1324, §3; §1, 8 of the 1983 Code of Canon Law). The Prefect of the Congregation for Bishops further expressed the hope that the Society would speedily return to "full communion" with the Church by showing "true fidelity and true acknowledgment of the Magisterium and the authority of the pope".[13]

The SSPX rejects the notion of "full" and "partial" communion with the Church, insisting that they belong to the Church according to the criteria given by Pope Pius XII, because they have the same faith, celebrate the same Sacraments, and recognise the same hierarchy of the Church. More recently, the Vatican has granted priests of the SSPX the authority to hear confessions and has authorised local ordinaries, in certain circumstances, to grant delegation to SSPX priests to act as the qualified witness required for valid celebration of marriage.[14] In each of these documents the hope was expressed that thereby "the process towards full institutional regularisation may be facilitated".

Sedeprivationists hold that the current occupant of the papal office is a duly-elected pope, but he lacks the authority and ability to teach or to govern unless he recants the changes brought by the Second Vatican Council.[7] Sedeprivationists teach that the popes from Pope John XXIII onward fall into this category.[7]

Traditionalist Catholic groups that espouse sedeprivationism include the Istituto Mater Boni Consilii, as well as the Orthodox Roman Catholic Movement among others.

Sedevacantists hold that the Vatican II popes have forfeited their position through their acceptance of heretical teachings connected with the Second Vatican Council and consequently there is at present no known true pope.[15] They conclude, on the basis of their rejection of the revised Mass rite and their rejection of certain aspects of postconciliar Church teaching as false, that the popes involved are also false.[16] This is a minority position among traditionalist Catholics[15][17] and a highly divisive one,[16][17] so that many who hold it prefer to say nothing of their view,[16] while other sedevacantists have accepted episcopal ordination from sources such as Archbishop Pierre Martin Ngô Đình Thục.[17]

The terms sedevacantist and sedevacantism derive from the Latin phrase sede vacante ("while the chair/see [of Saint Peter] is vacant"),[15] a term normally applied to the period between the death or resignation of one pope and the election of his successor.

The best-known, and likely best-organized Sedevacantist organization is the Congregation of Mary Immaculate Queen (CMRI). Many often refer to the Society of Saint Pius V (SSPV) as being a Sedevacantist organization as well; however, it has never formally adopted this position and considers the question of the validity of recent Papacies to be unresolved.

Conclavism is the belief and practice of some who, claiming that all recent occupants of the papal see are not true popes, elect someone else and propose him as the true pope to whom the allegiance of Catholics is due. They are often classified as sedevacantists because they reject the official papal succession for the same reasons. Conclavist groups include the

• "True Catholic Church", founded by Lucian Pulvermacher ("Pope Pius XIII")
• Palmarian Catholic Church, founded by Clemente Domínguez y Gómez ("Pope Gregory XVII")
• Pope Michael

Traditionalists' claims that substantive changes have taken place in Catholic teaching and practice since the Council often crystallise around the following specific alleged examples, in which others see not what Pope Benedict XVI called "discontinuity and rupture", but what he called "renewal in the continuity of the one subject-Church which the Lord has given to us":[21]

• A new ecclesiology which they claim fails to recognise the Catholic Church as the one true church established by Jesus Christ, and instead holds that the Roman Catholic Church is some sub-set of the Church founded by Christ. They see some of the confusion as stemming from an unclear understanding of the phrase "subsists in" which appears in the Vatican II document Lumen gentium, and which the Church has declared applies uniquely to the Catholic Church and means the "perduring, historical continuity and permanence of all the elements instituted by Christ in the Catholic Church, in which the Church of Christ is concretely found on this earth".[25] They claim that this "new ecclesiology" contradicts Pope Pius XII's Mystici corporis Christi and other papal documents.
• A new ecumenism which they see as aiming at a false pan-Christian religious unity which does not require non-Catholics to convert to the Catholic faith. They see this as contradicting the teachings of the Bible, Pope Pius XI's Mortalium animos, Pope Pius XII's Humani generis and other documents. See also Traditionalist criticism of ecumenism and criticism of doctrine on relations with non-Christians.
• In this connection, some traditionalist Catholics called it a blasphemy on the part of Pope Francis[26] when, in 2017, the Philatelic Office of Vatican City State, to commemorate the 500th anniversary of the Protestant Reformation issued a postage stamp showing Martin Luther and Philip Melanchthon kneeling with a penitential disposition on either side of the cross.[27][28]
• Acceptance of the principle of religious liberty as involving more than prudent religious tolerance, based on one interpretation of the Second Vatican Council's decree Dignitatis Humanae, allegedly in contradiction to Pope Pius IX's teachings in Quanta cura and the Syllabus of Errors.
• A revision of the Mass liturgy of the Roman rite which, they affirm, de-emphasises the central Catholic doctrines that the Mass is a true sacrifice and that the bread and wine are changed through transubstantiation into the body and blood of Jesus Christ, that it has been stripped of important prayers, that it is centered on the congregation rather than on God, that it is less beautiful and spiritually edifying, and that it omits certain Bible readings that mention subjects such as hell, miracles, and sin. Traditionalists hold differing opinions on the validity and acceptability of the revised rite of Mass:
  • Some see it as valid, and as acceptable when necessary, though the older form should be attended when possible.
  • Some, including the leadership of the Society of St Pius X, hold that it is in principle valid as a sacramental rite but maintain that the revisions in the liturgy are displeasing to God, and that it is often celebrated improperly to the extent of being sacramentally invalid. They therefore generally refuse to attend it.
  • Some, including many sedevacantists, see it as categorically invalid in principle and entirely unacceptable.[29]
  • Some hold that celebration of any modern-language translation even of the Tridentine Mass would have to be presumed invalid.[30]
• An inappropriate emphasis on the "dignity of man", which they claim ignores original sin and the need for supernatural grace, and which they also claim has led to a utopianism that sees world peace as possible without recognising the kingship of Christ. They see this orientation as contradicting Pope Pius XI's Quas primas, Pope Leo XIII's Rerum novarum, and other papal and conciliar documents.
• A teaching on collegiality that attributes to the bishops of the world a share, with the Pope, of responsibility for the Church's governance in a way that they claim is destructive of papal authority and encourages a "national" church mentality that undermines the primacy of the Holy See. They also claim that national bishops' conferences, whose influence was greatly increased following the Council, "diminish the personal responsibility of bishop[s]" within their dioceses.[31]
• A new and critical attitude towards the Bible that, they say, contradicts Leo XIII's Providentissimus Deus and Benedict XV's Spiritus Paraclitus, among other documents.
• A departure from the traditional belief that the Church and the world are at variance with one another to some degree, and that the Church has enemies. They believe that Pope Pius X's warnings in Pascendi Dominici gregis, Leo XIII's Humanum genus and other papal warnings against Freemasonry and other alleged enemies of Christianity have gone unheeded.

Georges de Nantes, a priest of the Diocese of Grenoble and founder of the traditionalist Catholic League for Catholic Counter-Reformation, criticized the Second Vatican Council for encouraging ecumenism and reform of the Church, and accused Pope Paul VI of heresy and of turning the Church into a movement for advancing democracy, a system of government that de Nantes abhorred. The Congregation for the Doctrine of the Faith issued a notification on 10 August 1969, stating that, as de Nantes continued to maintain his views on the Council, the aggiornamento of the Church, the French episcopate, and the "heresies" of Pope Paul VI, he thereby "disqualified the entirety of his writings and his activities".[32] It issued another notification in 1983, published on L'Osservatore Romano of 16–17 May of that year, stating that de Nantes had come to Rome to present a "Book of Accusation against Pope John Paul II for Heresy, Schism and Scandal", and that the Secretary of the Congregation had received him, as instructed by the Pope, but had refused to accept from him a book that contained unjustified gravely offensive accusations of the same character as those that de Nantes had directed against Pope Paul VI in a book published in 1973. It added that the refusal of de Nantes to retract his previous attacks on Pope Paul VI and the Second Vatican Council, to which he was now adding attacks on Pope John Paul II, made it impossible to believe in the sincerity of his declaration in 1978 and 1981 of a desire for the reconciliation for which the Pope remained always disposed.[33]

Those who in response to these criticisms by certain traditionalists defend the decisions of the Second Vatican Council and the subsequent changes made by the Holy See make the following counterclaims:

• They say that the criticisms are false, exaggerated, or lacking appreciation of the organic character of Tradition, and give as examples traditionalist criticisms that Dignitatis humanae contradicts the Church's earlier teaching on religious liberty,[34] and that the revised rite of Mass represents a break rather than a prudent development of the earlier liturgy.
• They say that traditionalists who claim that there has been a break from and discontinuity with the Church's traditional teaching are displaying a Protestant attitude of "private judgement" on matters of doctrine, instead of accepting the guidance of the Magisterium of the Church.[35]
• They say that such traditionalists fail to distinguish properly between changeable pastoral practices (such as the liturgy of the Mass) and the unchangeable principles of the Catholic faith (such as the dogmas surrounding the Mass).
• They say that traditionalists of this kind treat papal authority in much the same way as the dissident, liberal Catholics. While liberals believe that, on sexual matters, "the Pope can teach whatever he wants... but whether or not he should be listened to is very much an open question", the stance of certain traditionalists on the reform of the Mass liturgy and contemporary teachings on ecumenism and religious liberty amounts to the view that, on these issues, "faithful Catholics are always free to resist [the Pope's] folly.... As theories of religious dissent go, Catholic liberals couldn't ask for anything more."[36]
• The traditionalist claim that the Second Vatican Council was pastoral (and not infallible) is often countered by referring to Paul VI subsequently emphasizing the authoritative nature of the Council's teachings.[37]

Integrism is traditionalist Catholicism that integrates social and political contexts. Kay Chadwick writes: "It would be naive to suppose that [Catholic integrism] does not harbour a political agenda. It is anti-Masonic, anti-liberal and anti-Communist. It finds a voice in the Right-wing press. ... The annual Joan of Arc procession in Paris brings together integrists and National Front supporters. The annual National Front party celebration is preceded by a Latin Mass, celebrated in the pre-1970 form. Just before his death in March 1988, Lefebvre was fined eight thousand francs by the Court of Appeal in Paris for 'racial defamation' and 'incitement to racial hatred', for publicly suggesting that immigrants, beginning with Muslims, should be expelled from Europe. In 1976, he declared his support for Latin American dictatorships. He was an admirer of Maurras and Pétain, and supported the cause of French Algeria."[38]

The Southern Poverty Law Center (SPLC) used the term radical traditionalist Catholics to refer to those who "may make up the largest single group of serious anti-Semites in America, subscribe to an ideology that is rejected by the Vatican and some 70 million mainstream American Catholics. Many of their leaders have been condemned and even excommunicated by the official church."[39] The SPLC claims that adherents of radical traditional Catholicism "routinely pillory Jews as 'the perpetual enemy of Christ'",[39][40] reject the ecumenical efforts of the Vatican, and sometimes assert that all recent Popes are illegitimate.[39] The SPLC says that adherents are "incensed by the liberalizing reforms" of the Second Vatican Council (1962–65) which condemned hatred for Jewish people and "rejected the accusation that Jews are collectively responsible for deicide in the form of the crucifixion of Christ"[39] and that "Radical traditional Catholics" also embrace "extremely conservative social ideals with respect to women."[39]

The SPLC clarifies, however, "Radical traditionalists are not the same as Catholics who call themselves 'traditionalists' — people who prefer the old Latin Mass to the mass now typically said in vernacular languages — although the radicals, as well, like their liturgy in Latin."[39]

The best-known and most visible sign of Catholic traditionalism is an attachment to the form that the Roman Rite liturgy of the Mass had before the liturgical reform of 1969–1970, in the various editions of the Roman Missal published between 1570 and 1962. This form is generally known as the Tridentine Mass, though traditionalists usually prefer to call it the Traditional Mass. Many refer to it as the Latin Mass, though Latin is the language also of the official text of the post-Vatican II Mass, to which vernacular translations are obliged to conform, and canon law states that "the eucharistic celebration is to be carried out in the Latin language or in another language provided that the liturgical texts have been legitimately approved."[41] In his 2007 motu proprio Summorum Pontificum Pope Benedict XVI relaxed the regulations on use of the 1962 Missal, designating it "an" extraordinary form of the Roman Rite, as opposed to "the" ordinary or normal form, as revised successively by Pope Paul VI and Pope John Paul II.[42][43] In 2021, Pope Francis promulgated Traditionis custodes, amending and abrogating parts of Summorum Pontificum.[44]

Different traditionalist priests use different editions of the Roman Missal to celebrate the Tridentine Mass. Most, not only those in good standing with the Holy See but also such as those in the SSPX, use the 1962 edition, the only one that the Holy See authorises. A series of modifications to the 1962 liturgy introduced in 1965 are used by some traditionalists in good standing with Rome. This version of the liturgy is sometimes referred to as that of the "1965 Missal", though no new edition of the Roman Missal was in fact published in that year. The Priestly Fraternity of St. Peter, in an effort to get around the 1955 Holy Week reforms of Pius XII, which are part of the 1962 edition, has requested special permission from the Pontifical Commission Ecclesia Dei for provisional use of the older Holy Week rites "ad experimentum," beginning in 2018 and running through Holy Week 2020, at which point it will be determined whether the Holy See will grant a broader permission.

Since sedevacantists consider John XXIII not to have been a Pope, they reject the 1962 typical edition of the Roman Missal, which he promulgated. They generally use the 1920 typical edition, updated to some date previous to 1962. The Congregation of Mary Immaculate Queen follows the Missal as in 1955, accepting the changes introduced by Pius XII, but others reject his alteration of the calendar of saints and his revision of the rites of Holy Week.[45] Thus these others reject John XXIII's 1962 edition, which most notably featured the addition of St. Joseph to the enumeration of saints in the Roman Canon, and Pius XII's changes, seeing these changes as steps that led to the post-Vatican II Mass. There are no reports of priests regularly using any typical edition of the Missal earlier than that of 1920, which incorporated the rubrical and calendar changes made by Pope Pius X in 1910.[46]

Linked with the celebration of the Tridentine Mass is the observance of the liturgical calendar of saints' days as it existed before the revision of 1969 (see General Roman Calendar of 1960). Some also ignore the revisions of 1960 by Pope John XXIII, and of 1955 by Pope Pius XII, and use instead the General Roman Calendar of 1954.

Many traditionalist Catholics lay stress on following customs prevailing immediately before the Second Vatican Council, such as the following:

• Abstaining from meat on Fridays. Present discipline maintains Fridays and Lent as days and times of penance, declares that abstinence from meat or some other food as determined by the local episcopal conference is to be observed on all Fridays (excluding solemnities) and on Ash Wednesday, and allows episcopal conferences to permit other practices of personal penance to take the place of abstinence from meat.[47]
• Fasting from Midnight until the reception of Holy Communion.[48] The traditional Catholic rule of fasting from midnight until the reception of Holy Communion (this Eucharistic Fast is from both food and liquids), which is required by the 1917 Code of Canon Law, was shortened in 1953 by Pope Pius XII to a 3-hour fast.[48][49] In 1966, Pope Paul VI reduced the fast further to one hour, a rule included in the 1983 Code of Canon Law.[50] Many traditional Catholics will thus fast from midnight until they receive Holy Communion at Mass,[48] while others will keep a Eucharistic Fast for at least three hours.[51]
• Kneeling to receive Communion directly upon the tongue, under the Host species alone, and from the hand of a cleric rather than a layperson. Some would refuse to receive even from deacons, who, before the reforms of Pope Paul VI, were allowed to give Holy Communion only if there were a serious reason for permitting them to do so.[52] Many traditionalists regard the practice of receiving communion in the hand, though ancient[53][54] and authorised by the Holy See,[55] as an abuse[56] and as sacrilegious.
• Women wearing a headcovering when praying at home and when worshipping inside a church, as St. Paul required in 1 Corinthians 11:1-17 and which the 1917 Code of Canon Law required.[57] Accordingly, many traditionalist Catholic women wear a veil, a hat, or a headscarf when praying at home and when worshipping inside a church.[58][59]
• Frequent confession, a practice that grew in the first half of the 20th century, when increasingly frequent Communion led to more frequent confession.
• Prayers such as the Stations of the Cross and the Rosary in the form in use in the mid-20th century, and so without the alterations in the number and identity of the Stations that became common, though by no means universal, in the time of Pope Paul VI and without the addition of the Luminous Mysteries of the Rosary given as an option by Pope John Paul II.[60]

These practices are not confined to traditionalists: many mainstream Catholics also follow them. Likewise, they are not all followed by all traditionalist Catholics at all times.

Traditional Catholics, with respect to male and female gender roles, adhere to the doctrine of complementarianism.[61]

The standards of clothing among Traditional Catholics, based on instructions given by Pope Pius XI and consequently promoted by the Purity Crusade of Mary Immaculate, is referred to as "Mary-like Modesty", which includes for women, wearing sleeves "extending at least to the elbows" and "skirts reaching below the knees", as well as having a neckline no more than two inches with the rest of the bodice fully covered.[62][63][3]

Richard Williamson, then a bishop of the Society of Saint Pius X, stated that "women's trousers, as worn today, short or long, modest or immodest, tight or loose, open or disguised (like the "culottes”), are an assault upon woman's womanhood and so they represent a deep-lying revolt against the order willed by God."[4]

It is commonplace for women who identify as traditionalist Catholics to wear a head covering (veil) while praying at home and attending celebrations of the Mass.[58][59]

The Society of Saint Pius X (SSPX) opposes the presence of television in the household, teaching that it is an occasion of sin.[64]

Even before the Second Vatican Council the Holy See declared it important to guard and preserve whole and entire forever the customs and distinct forms for administering the sacraments in use in the Eastern Catholic Churches (Pope Leo XIII, encyclical Orientalium Dignitas).[65] Leo's successor Pope Pius X said that the priests of the newly created Russian Catholic Church should offer the Divine Liturgy Nec Plus, Nec Minus, Nec Aliter ("No more, No Less, No Different") than priests of the Russian Orthodox Church and the Old Believers.[66][67]

In the Ukrainian Greek Catholic Church, liturgical de-latinization began with the 1930s corrections of the liturgical books by Metropolitan Andrey Sheptytsky. According to his biographer Cyril Korolevsky, Metropolitan Andrey opposed use of coercion against those who remained attached to Latin liturgical practices, fearing that any attempt to do so would lead to a Greek-Catholic equivalent of the 1666 Schism within the Russian Orthodox Church.[68]

De-latinization in the UGCC gained further momentum with the 1964 decree Orientalium Ecclesiarum of the Second Vatican Council) and several subsequent documents. Latinisations were discarded within the Ukrainian diaspora, while among Byzantine Catholics in Western Ukraine, forced into a clandestine existence following the Soviet ban on the UGCC, the latinizations remained, "an important component of their underground practices",[69] in illegal parishes, seminaries, and religious communities. After proscription of the UGCC was lifted in 1989, priests and hierarchs arrived from the diaspora and began to enforce a liturgical conformity that met with opposition.

In response, many priests, nuns, and candidates for the priesthood found themselves, "forced towards the periphery of the church since 1989 because of their wish to 'keep the tradition'." In some eparchies, particularly those of Ivano-Frankivsk and Ternopil-Zboriv, the bishops would immediately suspend any priest who, "displayed his inclination toward 'traditionalist' practices".[70]

Vlad Naumescu reports that an article in the February 2003 issue of Patriayarkhat, the official journal of the Ukrainian Greek-Catholic Church, written by a student of the Ukrainian Catholic University, which since its 1994 foundation has been, "the strongest progressive voice within the Church". The article named priests and parishes in every eparchy in Ukraine as being involved in "a well-organized movement" and who described themselves as "traditionalists". According to the article, they constituted "a parallel structure" with connections with the Society of St. Pius X and with a charismatic leader in Fr. Basil Kovpak, the Pastor of St. Peter and Paul's Church in the suburb of Lviv-Riasne.[71]

According to Vlad Naumescu, "Religious life in a traditionalist parish followed the model of the 'underground church.' Devotions were more intense, with each priest promoting his parish as a 'place of pilgrimage' for the neighboring areas, thus drawing larger crowds on Sunday than his local parish could provide. On Sundays and feast days, religious services took place three times a day (in Riasne), and the Sunday liturgy lasted for two and a half to three hours. The main religious celebrations took place outside the church in the middle of the neighborhood, and on every occasion traditionalists organized long processions through the entire locality. The community was strongly united by its common opponent, re-enacting the model of the 'defender of faith' common to times of repression. This model, which presupposes clear-cut attitudes and a firm moral stance, mobilized the community and reproduced the former determination of the 'underground' believers."[72]

The Priestly Society of Saint Josaphat (SSJK), which operates a seminary, Basilian convent, and numerous parishes, receives priestly orders from the bishops of the SSPX. Its superior, Father Basil Kovpak, has accused the UGCC hierarchy of using intense psychological pressure against priests who are reluctant or unwilling to de-Latinise. He alleges that numerous laity, attached to the Latinisations since the Soviet persecution of the UGCC, would prefer to stay home on Sunday rather than attend a de-Latinised liturgy.

The SSJK opposes removal of the stations of the cross, the rosary and the monstrance from the liturgy and parishes of the Ukrainian Greek Catholic Church. They also reject replacement of the UGCC's liturgical language, Old Church Slavonic, with the vernacular Ukrainian language. In his memoir Persecuted Tradition, Kovpak also mentions many examples of the UGCC turning away Orthodox clergy and laity who wish to convert to Eastern Catholicism. In many cases, he alleges, this is because the converts are not ethnically Ukrainian. Fr. Kovpak called this a betrayal of the efforts by Pope Pius X, Metropolitan Andrey Sheptytsky, and Exarch Leonid Feodorov to create the Russian Greek Catholic Church and to convert the Russian people.

In 2004, the year after the publication of Fr. Kovpak's book, Cardinal Lubomyr excommunicated Kovpak from the Ukrainian Greek Catholic Church. Kovpak appealed this punishment at the papal Sacra Rota Romana in Vatican City and the excommunication was declared null and void for lack of canonical form.

In 2006, the SSJK got Latin Bishop Richard Williamson, at that time a member of the SSPX, to ordain two priests and seven deacons in Warsaw, Poland, an action that violated canons 1015 §2, 1021 and 1331 §2 of the Code of Canon Law and the corresponding canons of the Code of Canons of the Eastern Churches.

Fr. John Jenkins, an SSPX priest who was present, later remarked, "We were all very edified by their piety, and I myself was astonished by the resemblance of the atmosphere amongst the seminarians with that which I knew in the seminary – this in spite of the difference of language, nationality and even rite."[73]

Archeparch Ihor Vozniak of Lviv, the Archeparchy in which the PSSJ is most active, denounced the ordinations as a "criminal act", and condemned Fr. Kovpak's participation in the ceremony. He stressed that the two priests whom Bishop Williamson had ordained would not receive faculties within the Archeparchy.[74] Officials of the Lviv archdiocese said that Kovpak could face excommunication, and that "'he deceives the church by declaring that he is a Greek (Byzantine) Catholic priest,' while supporting a group [SSPX] that uses the old Latin liturgy exclusively, eschewing the Byzantine tradition, and does not maintain allegiance to the Holy See."[75]

Father Kovpak's excommunication process was restarted by the hierarchy of the Ukrainian Greek-Catholic Church and was confirmed by the Congregation for the Doctrine of the Faith on 23 November 2007.[76]

On 3 March 2008 a group of Basilian priests stationed in Pidhirtsi, Ukraine, informed Pope Benedict XVI that four of them had been consecrated as bishops in order to save the Ukrainian Greek Catholic Church (UGCC) from heresy and apostasy. On 11 August 2009, they announced the formation of the Ukrainian Orthodox Greek Catholic Church as a "new Church structure for the orthodox faithful of the UGCC", professing the Catholic faith, including the primacy of the Roman Pontiff, and disassociating themselves from "contemporary heresies which destroy both the Eastern and the Western Church".[77] Having elected Czech Basilian priest Fr. Anthony Elias Dohnal as "Patriarch Elijah", they declared on 1 May 2011 that both Pope John Paul II and Pope Benedict XVI were excommunicated and that the Holy See was vacant (Sedevacantism). They added: "The Byzantine Catholic Patriarchate is now commissioned by God to protect the orthodox doctrine of the Catholic Church, including the Latin Church. Only after an orthodox Catholic hierarchy and an orthodox successor to the Papacy is elected, will the Patriarchate be relieved of this God-given duty."[78][79]

On 29 September 2019, Patriarch Elijah of the UOGCC issued "an anathema [...] on 26 cardinals, 134 bishops and 99 priests, participants in the [...] Amazon Synod"[80]

On 14 October 2019, the UOGCC broke with their former policy of Sedevacantism and embraced Conclavism. They announced they had elected Archbishop Carlo Maria Viganò, the former Apostolic Nuncio to the United States, as their Pope.[81][82]

In a 2014 article in The New York Times about the UOGCC, Patriarch Elijah and his followers were alleged to be Pro-Russian, anti-Ukrainian, and violently opposed to the 2014 Ukrainian Revolution. In the same article, Kyr Ihor Vozniak, UGCC Archeparch of Lviv, was quoted as saying that the UOGCC is financed and secretly led by the Foreign Intelligence Service of the Russian Federation in order to introduce anarchy and chaos into the Ukrainian Greek Catholic Church.[83]

According to the Lviv-based newspaper Ekspres, Fr. Dohnal, alias Patriarch Elijah, was a KGB informer inside the Roman Catholic Diocese of Litoměřice before the Fall of Communism in the Czechoslovak Socialist Republic. In support of their claims, Ekspres published a document identifying Fr. Dohnal as a KGB mole with the code name “Tonek.” The UOGCC denies the accusation.

The Pontifical Commission Ecclesia Dei was founded in July 1988 in the wake of Pope John Paul II's apostolic letter Ecclesia Dei. Pope Benedict XVI was a member of the Commission during his tenure as Cardinal Prefect of the Congregation for the Doctrine of the Faith. Speaking on 16 May 2007 to the Fifth General Conference of the Bishops of Latin America and the Caribbean, Cardinal Castrillón, the current head of the Commission, stated that his department had been founded for the care of those "traditionalist Catholics" who, while discontented with the liturgical reform of the Second Vatican Council, had broken with Archbishop Marcel Lefebvre, "because they disagreed with his schismatic action in ordaining Bishops without the required papal mandate". He added that at present the Commission's activity is not limited to the service of those Catholics, nor to "the efforts undertaken to end the regrettable schismatic situation and secure the return of those brethren belonging to the Fraternity of Saint Pius X to full communion." It extends also, he said, to "satisfying the just aspirations of people, unrelated to the two aforementioned groups, who, because of their specific sensitiveness, wish to keep alive the earlier Latin liturgy in the celebration of the Eucharist and the other sacraments."[84]

In the same speech Cardinal Castrillón indicated that it was intended to make the Commission an organ of the Holy See for the purpose of preserving and maintaining the traditional liturgy; at the same time he stated that this was not with the purpose of "going backward, of returning to the times before the 1970 reform.... The Holy Father wishes to preserve the immense spiritual, cultural and aesthetic treasure linked with the old liturgy. Recovery of these riches goes together with the no less precious riches of the Church's present liturgy." In 2019, Pope Francis suppressed this commission and transferred its responsibilities directly to the Congregation for the Doctrine of the Faith.

Following months of rumour and speculation, Pope Benedict XVI issued the motu proprio Summorum Pontificum in July 2007. The Pope ruled that priests of the Latin Church can freely choose between the 1962 Roman Missal and the later edition "in Masses celebrated without the people".[85] Such celebrations may be attended by those who spontaneously ask to be allowed.[86] Priests in charge of churches can permit stable groups of laypeople attached to the earlier form to have Mass celebrated for them in that form, provided that the celebrating priest is "qualified to [celebrate] and not juridically impeded"[87] (this would exclude traditionalist priests not in good standing with Rome). In 2021, Pope Francis issued Traditionis custodes, which severely restricted the use of the Extraordinary Form for those not addressed by Ecclesia Dei.

The document, as well as being welcomed by the traditionalist groups that have been in good relations with Rome, has been considered by groups such as the Sons of the Most Holy Redeemer, which have been in dispute with Rome, to be sufficient grounds for seeking an agreement.[88] The Society of Saint Pius X welcomed the document, but referred to "difficulties that still remain", including "disputed doctrinal issues" and the notice of excommunication that still affected its bishops.[89] Sedevacantists of course consider all documents issued by Benedict XVI to be devoid of canonical force.
