“That constitutes apostasy, Joe!” By this point, Mel Gibson had been chewing the fat with Joe Rogan for half an hour — and his publicist was probably having a stroke. He went on Rogan’s podcast earlier this year to promote his new movie, Flight Risk, a plane-hijacking thriller. But he ended up accusing the leaders of the Catholic Church of apostasy in the style of a medieval inquisitor.
Gibson, a staunch Catholic, was livid about a ceremony conducted at the Vatican in 2019. During the Amazon Synod, held to discuss the Church in the Amazon region, wooden statues of the Amazonian goddess Pachamama were dotted around the Vatican gardens. At one point, inside St. Peter’s Basilica, Pope Francis led a prayer while facing a small carving of the Pachamama.
For Gibson, who has been appointed Special Envoy to Hollywood by President Trump, this episode represents everything that has gone wrong with the Church. He blames it on “an inside job”. And, in his eyes, it all started at the Second Vatican Council — or Vatican II — which took place from 1962 to 1965. Its purpose: to modernise Catholicism. After that, the Church became “something else” entirely, Gibson told Rogan. That something else, as far as he is concerned, is a sham. “I don’t adhere to a post-conciliar Church,” he said.
He doesn’t sound like your ordinary disgruntled Catholic. In fact, Gibson was echoing the key tenets of a ragtag movement known as sedevacantism.
The sedevacantists take their name from the Latin phrase sede vacante, meaning the See of Rome is vacant. The phrase is typically used to describe the period between the death of a pope and the election of his successor, when the papacy is unoccupied. Sedevacantists, however, believe that the papacy has been unoccupied since Vatican II. There have been six popes since then, but none are considered legitimate.
There are at most 30,000 sedevacantists in dozens of distinct organisations worldwide. The movement originated in Mexico in the mid-Sixties, where a priest named Joaquín Sáenz y Arriaga came up with its core tenet: the Church post-Vatican II was “headless”. Predictably, that didn’t go down well with His Headless Holiness, and Sáenz y Arriaga was excommunicated. The movement spread in the Seventies, after it was endorsed by Michel-Louis Guérard des Lauriers, a French friar and the personal confessor to Pius XII. As the last pope before Vatican II, Pius is considered the last legitimate pontiff by sedevacantists. This makes Guérard des Lauriers something of a cult hero.
Now, the movement has moved online. The meme-posting page Novus Ordo Watch boasts more than 25,000 followers on X and 13,000 followers on Facebook. Its logo is a sketch of Pius XII (of course), with the tagline: “Unmasking the Modernist Church of Vatican II”.
So, what really happened at this dreadful council that left the sedevacantists stricken? The conventional narrative of Church reform goes like this: Vatican II was called in 1959 by Pope John XXIII, who thought the Church was in dire need of aggiornamento — an update. He believed that if it wanted to thrive in the 20th century, Catholicism would have to ditch dusty dogmas and embrace the modern world. “Through Vatican II, the Church sought to re-engage with an increasingly secularised world,” the historian Jessica Wärnberg told me.
This re-engagement crusade took several forms. Vatican II did away with the belief that there was no salvation outside the Church. From then on, non-Catholics could be redeemed. Religious liberty was embraced as the unalienable right of every human being: other religions were to be held in esteem, and antisemitism was denounced.
Vatican II also overhauled the liturgy. Up until then, Mass had been conducted in Latin; the priest had his back to the congregation and faced the altar. But at the council, it was decided that Mass would be conducted in the national language so as to be more inclusive. The priest would face the congregation. The Latin Mass wasn’t abolished, but it became much rarer.
This was a seismic moment for practising Catholics. For many, it was as if the religion they had followed since childhood, that had given meaning to their lives, had suddenly been taken away from them. The refashioned Mass hit particularly hard. At the time, French President Charles de Gaulle is said to have remarked that Vatican II was “the most important event of the century, because you can’t change the prayer of a million men and women without affecting the balance of the planet”.
Millions of conservative Catholics felt aggrieved. Most of them, however, didn’t embrace sedevacantism. It was too radical, too weird, for them. Rather than flee their besieged Church, they chose to stay in it and fight. Their mission: the preservation of the old ways.
These Catholics are usually referred to as traditionalists, and they share many of the same grievances as sedevacantists. They attend Mass in Latin and are critical of the direction of the Church. Yet they stop short of breaking ties with the Holy See, remaining in communion with the Pope. While traditionalists think like reformers, hoping to change the system from within, sedevacantists think like revolutionaries. They want to bring down the whole corrupted system.
Enter a Catholic with chiselled looks named Hutton Gibson, father of Mel. In 1977, he started a newsletter called The War is Now! Think Substack in the analogue age. “This journal has but one purpose: complete recovery of our Church!” Hutton wrote in the first instalment. Then, in the hallowed tradition of the Holy Office of the Inquisition, he went after his enemies: “To all who promoted the current deviation… may they roast eternally in the deepest pit of hell!”
Hutton would go on to become one of the leading lights of the sedevacantist movement, writing a series of self-published books. He would argue that Vatican II was actually “a Masonic plot backed by the Jews”, which had rigged the conclave that had elected John XXIII in 1958. In his telling, another cardinal, the arch-conservative Giuseppe Siri, had been elected. But the Jewish-backed Masons had threatened “to atom-bomb Vatican City” if they didn’t get their candidate. John XXIII, a secret Mason, became pope instead.
As Hutton’s tale suggests, sedevacantism is a wonderland of alternative facts, which is another reason why traditionalists steer well clear of it. At its core, sedevacantism isn’t a theological stance; it’s a conspiracy theory. Call it Catholic QAnon, for just like QAnon, it has become a magnet for haters, weirdos, and phonies.
“Sedevacantism isn’t a theological stance; it’s a conspiracy theory. Call it Catholic QAnon.”
Take Francis Schuckardt, the founder of the Tridentine Latin Rite Church, who in the Seventies crisscrossed America to preach the Bad News: Vatican II had destroyed the Catholic Church. The Pope was demonic, and any Catholic who followed him would be damned — that is, unless they followed Bishop Schuckardt. Hundreds of lost souls fell for it.
The Tridentine Latin Rite Church became a site of horrors. Schuckardt was a sexual predator who regularly assaulted seminarians, according to writer Michael W. Cueno’s The Smoke of Satan. Whenever the nuns were deemed to have misbehaved, they were imprisoned in freezing attics for several weeks. Congregants were mistreated too: nuns once force-fed rotten food to a young girl; after she threw up, she was made to eat her own vomit. “Lick the vomit clean,” one nun yelled while beating her.
The truth was exposed by the press in 1984. Schuckardt took off with his most loyal followers and $250,000 in cash. He tried to get another church off the ground in California, but in 1987 a SWAT team raided his compound. They found drugs, automatic weapons, and gruesome documents about body dismemberment. Schuckardt served a stint in jail and died in 2006.
Another sedevacantist thought leader was Veronica Lueken, a Catholic housewife from Queens, New York. One day in 1968, according to the academic Joseph P. Laycock’s The Seer of Bayside, Lueken started hearing voices. Then the visions began. One time, she saw a giant face in the sky: it was Jesus Christ himself. Soon after that, the Virgin Mary spoke to her from heaven. Surprise, surprise, the Blessed Mother hated Vatican II.
Like a medieval soothsayer, Lueken attracted a sizeable following. People from all over the US would flock to Queens to see her in a trance. Her neighbours cursed her. Local restaurateurs thanked the Good Lord for their fortune and set up hot dog stalls for the hungry pilgrims.
In 1975, Mary finally let Lueken in on the secret behind Vatican II. “My child, I bring to you a sad truth, one that must be made known to mankind,” Lueken recalls being told. Paul VI, who promulgated Vatican II, had been replaced by a lookalike. “There is one who is ruling in his place, an impostor, created from the minds of the agents of Satan,” Mary supposedly said. How was that possible? “Plastic surgery, my child — the best of surgeons were used to create this impostor.”
Not every sedevacantist would pay homage to Lueken. The movement is divided between a myriad of splinter groups, and each group insists on its particular definition. To complicate matters, a few reject the term sedevacantist and will go ballistic if you call them one. Some prefer the term sedeprivationism, which holds that the popes are popes “materially but not formally”. Others still insist they are simply “true” Catholics who follow the age-old teachings of the Church. But these are marginal distinctions: all ascribe to the same core doctrine. In this, they resemble Leninists, Trotskyists, and Stalinists squabbling over the correct definition of Marxism.
However, just as communists hate the moderate Left, sedevacantists are united in their contempt for traditionalist Catholics. Despite fighting similar battles, the two groups are far from brother in arms, with sedevacantists regarding traditionalists as traitors in the pocket of the Holy See.
One target of sedevacantist ire is the Society of St Pius X — SSPX for connoisseurs — a hardline traditionalist organisation which has 600,000 members worldwide. It was founded in 1970 by Marcel Lefebvre, a French archbishop who had led the charge against Vatican II.
Lefebvre often spoke like a sedevacantist. Vatican II was “satanic”. It was the result of an alliance between “the highest authorities of the Church and of masonic lodges”. Therefore, Lefebvre concluded, “this conciliar Church is not Catholic. In so far as the pope, bishops, priests and the faithful adhere to this new Church, they are separating from the Catholic Church.” But Lefebvre never became a sedevacantist. He realised that the Vatican was where the power was, and he always hoped to have more influence within the Church than outside it. He entered into negotiations with Rome several times, to no avail. In the end, Lefebvre was excommunicated in 1988 after ordaining bishops without authorisation.
In the eyes of sedevacantists, Lefebvre was a weakling. In 1983, a group of exasperated followers left SSPX, claiming Lefebvre was “far too soft”. In a feat of imagination, they called their new organisation the Society of St Pius V, or SSPV. But even SSPV wasn’t hardline enough for the most committed of sedevacantists. In the Nineties, a handful of true believers broke away and joined the Congregation of Mary Immaculate Queen, which was itself a splinter group from the Tridentine Latin Rite Church.
The sedevacantists have no intention of standing by while an imposter rules the Vatican. And so, in order to save the one true Church, the most pious of them have taken one for the team and proclaimed themselves popes. There was Pope Michael I, born David Bawden. A former SSPX member, Bawden proclaimed himself pope in the Nineties. He took over a dollar store in rural Kansas to hold a conclave. His College of Cardinals consisted of his parents, three friends, and himself. There was also Pope Pius XIII, born Lucian Pulvermacher. His conclave took place in 1998 in a log cabin in the mountains of Montana.
The most high-profile antipope yet is Peter III, born Markus Josef Odermatt, the leader of the Palmarian Catholic Church, which is based near Seville, Spain. The Church, though not technically sedevacantist, is essentially a cult: there are around 5,000 Palmarians, who are tightly controlled, encouraged to reproduce (some families have 15 kids), and taught that Adolf Hitler and Francisco Franco are saints.
Peter III’s predecessor, Gregory XVIII, quit the organisation in 2016 and exposed it as a massive scam. “It’s all a set-up, particularly a financial one,” he said. “They’re just using the miracle of the Virgin Mary as a front.” The whole thing is allegedly bankrolled by donations from wealthy businessmen and may be a front for money-laundering.
It’s tempting, perhaps, to dismiss the sedevacantists as a joke — a droll footnote in the long history of the Catholic Church. But to do so would be to underestimate their influence. While sedevacantism remains a fringe movement, its rhetoric has seeped into Catholic conservative circles in recent years. There is the same sense of paranoia and betrayal, and the same belief that the Church is under threat.
The trigger has been Pope Francis himself. Although he isn’t the firebrand progressive portrayed in the media, he is a liberal. The pontiff has reformed the Vatican and tried to make the Church less judgemental and more inclusive: in 2023, for example, he allowed priests to bless same-sex couples.
The backlash has been nasty. From the moment he became pope, Church conservatives have been out to get Francis. At times, they’ve sounded a lot like sedevacantists. Cardinal Robert Sarah is a prime example. To be clear, he has never openly questioned the validity of Francis’s election. That would be grounds for excommunication. But the Cardinal has not minced words. Francis’s decision to let same-sex couples receive blessings was, he said, “a heresy that seriously undermines the Church, the Body of Christ, because it is contrary to the Catholic faith and Tradition”.
By Vatican standards, such a comment is outrageous. The Holy See, lest we forget, is an absolute monarchy. Francis is the supreme pontiff. While he’s not above criticism, insinuating that he’s betraying Catholicism crosses a red line.
But there is more. Just two months ago, Sarah said that any attempt to abolish the Latin Mass would be akin to “a diabolical project that seeks to break with the Church of Christ”. This was surely a dig at Francis, who has severely restricted the use of the Latin Mass. Rumours abound that he wants to abolish it altogether. Sarah’s remark borrowed heavily from sedevacantist lore. The implications are clear: the Church might fall under the sway of the Devil. And none other than the Pope might be responsible.
Cardinal Raymond Burke has gone even further. He has not only rejected Francis’s teachings, but also cast aspersions on the Pope’s legitimacy. “Many have expressed their concerns to me. At this very critical moment, there’s a strong sense that the Church is like a ship without a rudder,” Burke said in 2014. “They are feeling a bit seasick because they feel like the Church’s ship has lost its way.” A ship without a rudder. Burke was aping the core tenet of sedevacantism: the Church (the ship) was without a pope (the rudder). The Cardinal later put out a statement making a distinction between “the person of Pope Francis” and “the divine gift of the Petrine Office”.
There were doubts over whether Burke still recognised Francis as Pope. A Catholic website published an article headlined “Does Cardinal Burke think Francis is an antipope?” In 2019, Ross Douthat of The New York Times even questioned Burke about it: “You believe Francis is a legitimate pope?” It beggars belief — here was a leading newspaper asking a cardinal of the Roman Catholic Church if he was a sedevacantist. In the end, Burke clarified that, of course, he does believe Francis is the Pope. Nonetheless, he admitted that “people are getting more and more extreme in their response to what’s going on in the Church”.
On that point, Burke is right. The Francis papacy has broken traditionalists. Many are losing faith that they can ever change the Church from within. Angry and increasingly desperate, some openly flirt with sedevacantism. Even if most traditionalists don’t come out as sedevacantists, the damage to the Church is considerable.
The Church has struck back. In 2024 the Vatican excommunicated Carlo Maria Viganò, a traditionalist archbishop, for schism. He was found guilty of “refusal to recognize and submit to the Supreme Pontiff… and of the legitimacy and magisterial authority of the Second Vatican Council”.
Viganò sure sounds like a sedevacantist. “We have a deep church that has infiltrated and occupied the Catholic Church,” Viganò said last month. “The members of this counter-church have transformed the Catholic Church into an organization in support of the woke globalist Left.” Predictably, he has won plaudits from some lay conservative Catholics. Among them is Brian Burch, Trump’s Ambassador to the Holy See and a vocal critic of the Pope. “Viganò may not have everything right,” Burch said in 2020. “But there is one thing of which I am certain; Satan is real, and he is on the prowl.”
The story of the sedevacantists is a parable for our times: it shows how extremism goes mainstream. It starts when progress is achieved — a handful of zealots lose their minds and, at the start, everyone ignores them. But, over time, their conspiratorial paranoia takes root. Next thing you know, what sounded preposterous has become legitimate discourse.
But a final question remains: is their ultimate fantasy — to overturn Vatican II — possible? Could the traditionalists inside the Church regain control of the Holy See and coax them back into the fold? Could the next pope redeem them?
The polite answer is that it would take a miracle. Francis has appointed 80% of the cardinals who will elect the next pontiff. “I’m not saying he will be a progressive,” says Frédéric Martel, a sociologist and the author of In the Closet of the Vatican, “but he probably won’t be an ultra-conservative.”
It seems that sedevacantists have lost the holy war — but at least they can take comfort in the knowledge that their usurpers will roast eternally in the deepest pit of hell.
