is vacant.
Sedevacantism owes its origins to the rejection of the theological and disciplinary changes implemented following the
Second Vatican Council (1962–1965).
The term ''sedevacantism'' is derived from the Latin phrase , which means "the chair
f the Bishop of Rome">Bishop_of_Rome.html" ;"title="f the Bishop of Rome">f the Bishop of Romebeing vacant".
The phrase is commonly used to refer specifically to a vacancy of the Holy See which takes place from the pope's death or
renunciation to the Papal conclave">election of his successor.
The number of sedevacantists is unknown and difficult to measure; estimates range from tens of thousands to hundreds of thousands. Various factions of conclavism">conclavists among sedevacantists have proceeded to end the perceived vacancy in the Holy See by electing their own pope.
Etymology
The term ''sedevacantism'' derives from the Latin term ''sede vacante'', which means "with the chair being vacant".
In the Catholic Church, when an episcopal see becomes vacant due to the death or removal of a Bishop from office for whatever reason, in the interim the diocese is automatically in a state of ''sede vacante'', until a new designate is appointed and duly elevated to his see. With Sedevacantism, this is specifically in reference to the See of
Saint Peter, i.e., the Catholic
Papacy

In 1965, at a private meeting in the house of Anacleto González Guerrero (son of the ''Cristero'' martyr

Paul VI (Giovanni Montini) was a crypto-Jew and an illegitimate Pope, and that this line should be officially adopted as the position of Mexican traditionalists.

under Ramón Plata Moreno, known as ''
El Yunque'', although ultra-conservative as well and unhappy about the liberalising changes in the Catholic world, rejected the proposal, stating that Pope Paul VI was indeed the legitimate Pope of the Catholic Church. This led to a deadly split in the Mexican traditionalist scene.
Earlier, during the Second Vatican Council, ''Los TECOS'' had distributed the document entitled ''Il Complotto contro la Chiesa'' ("The Plot Against the Church") under the pseudonym of Maurice Pinay, warning Council fathers of a supposed “Judeo-Masonic-Communist” plot to infiltrate and destroy Christianity and the Catholic Church.
Another early expositor from Latin America was
Carlos Alberto Disandro in Argentina, a personal associate of
Juan Perón, belonging to the Catholic wing of
orthodox Peronism, who raised the question in 1969 with his book ''Pontificado y Pontífice: una breve quaestio teológica''.
Positions
Origin
Sedevacantism owes its origins to the rejections of theological and disciplinary changes implemented following the
Second Vatican Council (1962–1965). Sedevacantists reject this Council, on the basis of their interpretations of its documents on
ecumenism and
religious liberty, among others, which they see as contradicting the traditional teachings of the Catholic Church and as denying the unique mission of Catholicism as the
one true religion,
outside of which there is no salvation. They also say that new disciplinary norms, such as the
Mass of Paul VI
The Mass of Paul VI, also known as the Ordinary Form or , is the most commonly used Catholic liturgy, liturgy in the Catholic Church. It was Promulgation (Catholic canon law), promulgated by Pope Paul VI in 1969 and its liturgical books were p ...
promulgated on 3 April 1969, undermine or conflict with the historical Catholic faith and are deemed
blasphemous, while post-Vatican II teachings, particularly those related to ecumenism, are labelled
heresies. They conclude, on the basis of their rejection of the
revised Mass rite and of postconciliar church teaching as false, that the popes involved are also false.
Among even
traditionalist Catholics,
this is a quite divisive question.
Traditionalist Catholics who are not sedevacantists recognize the line of popes leading to and including
Pope Leo XIV
Pope Leo XIV (born Robert Francis Prevost, September 14, 1955) has been head of the Catholic Church and sovereign of the Vatican City State since May 2025. He is the first pope to have been born in the United States and North America, the fir ...
as legitimate. Sedevacantists, however, claim that the infallible
Magisterium of the Catholic Church could not have decreed the changes made in the name of the Second Vatican Council, and conclude those who issued these changes could not have been acting with the authority of the Catholic Church. Accordingly, they hold that
Pope John XXIII and his successors
have left the true Catholic Church and thus lost legitimate authority. A
notorious heretic, they say, cannot be the Catholic pope.
Justification
While sedevacantist arguments often hinge on interpretations of
modernism

, this is also debated.
Positions within sedevacantism
Clergy, Mass, and sacraments
Some sedevacantists accept the consecrations and ordinations of sedevacantist bishops and priests, and the offering of Masses and the administration of sacraments by the said bishops and priests, to be
licit because of ''epikea'',
i.e. "the interpretation of the mind and will of him who made the law". In this case, the
ecclesiastical laws (e.g. prohibition of consecrations of bishops without papal mandate; prohibition of administration of sacraments without ecclesiastical authorization) are interpreted to cease when to follow them would be impossible, harmful, or unreasonable, or would mean transgressing
divine laws (e.g. the church must have bishops and priests; Catholics must attend Mass and receive the sacraments), and because of a historical precedent for consecrating Catholic bishops during a long vacancy of the Holy See.
Liturgy
Anthony Cekada considers that a question among sedevacantists is whether it is permissible to go to Masses. These are Traditional Latin Masses naming the man considered by the majority of Catholics as the Pope in the
Roman Canon in the prayer, specifically where the priest says (“together with Your Servant N., our Pope.”) Cekada argues that it is not, under any circumstances, permissible.
Relationship to sedeprivationism
In contrast to sedevacantists,
sedeprivationists affirm the
Thesis of Cassiciacum by the
Dominican theologian Bishop
Michel-Louis Guérard des Lauriers as being a valid position, which states that John XXIII and his successors are popes (“
materially but not formally”), and that post-Vatican II popes will become legitimate once they recant their heresies.
This position is endorsed by the .
Demography
There are estimated to be between several tens of thousands and more than two hundred thousand sedevacantists worldwide, mostly concentrated in the United States, Mexico, Canada, France, the United Kingdom, Italy and Australia, but the actual size of the movement has never been accurately assessed. It remains extremely difficult to do so for a wide range of reasons, such as the fact that not all sedevacantists identify as such, nor do they necessarily belong to avowedly sedevacantist groups or societies.

Thục-line bishops
Some bishops derive their
episcopacy from Archbishop
Thục or bishops of his lineage. Many of these bishops belong to the non-sedevacantist
Palmarian Catholic Church; this is due to Thục having consecrated Bishop
Clemente Domínguez y Gómez, later the
Pope of the Palmarian Church, and the episcopal consecrations within this organization.
On 7 May 1981, Thục consecrated the
sedeprivationist French priest
Michel-Louis Guérard des Lauriers as a bishop.
[ Des Lauriers was a French Dominican theologian and a papal advisor.][M.L. Guérard des Lauriers, Dimensions de la Foi, Paris: Cerf, 1952.]
On 17 October 1981, Thục consecrated the sedevacantist Mexican priests Moisés Carmona and Adolfo Zamora as bishops.[ Carmona and Zamora had been sedevacantist leaders and propagators in Mexico.
The Vatican declared Thục '' latae sententiae'' excommunicated for these consecrations and for his declaration of Sedevacantism.]
Méndez-line bishops
On 19 October 1993, in Carlsbad, California, United States, Bishop Méndez-Gonzalez consecrated the sedevacantist Clarence Kelly of the Society of Saint Pius V

(SSPV) to the episcopacy. By Méndez's wish, the consecration was kept secret until his death in 1995.
Whose lineages derive from earlier movements
A considerable number of sedevacantist bishops are thought to derive their holy orders from Bishop Carlos Duarte Costa, who in 1945 set up his own independent Brazilian Catholic Apostolic Church. While Duarte Costa was not a sedevacantist, he instead questioned the papacy as an institution, denying papal infallibility
Papal infallibility is a Dogma in the Catholic Church, dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Saint Peter, Peter, the Pope when he speaks is preserved from the possibility of error on doctrine "in ...

Benevacantism
A separate minority position called Benevacantism (a portmanteau of "Benedict" and "''sedevacantism''") holds that Pope Benedict XVI
Pope BenedictXVI (born Joseph Alois Ratzinger; 16 April 1927 – 31 December 2022) was head of the Catholic Church and sovereign of the Vatican City State from 19 April 2005 until his resignation on 28 February 2013. Benedict's election as p ...
