Thiel's Framing of Proponents of an AI Treaty as 'Antichrist' Collides with 60 Years of Catholic Doctrine
Peter Thiel has been lecturing — in San Francisco, Paris, and last March steps from the Vatican — that global institutions created to manage AI safety risks are the face of the Antichrist: a technocratic world government that trades freedom for false safety. It is a rhetorically powerful move.
But it runs directly into one of the most deeply rooted and consistent bodies of Catholic Social Teaching: the Church’s six-decade insistence that existential threats like nuclear weapons require strong, enforceable international institutions — and that no single state can manage them alone. At the heart of that teaching is a conviction about the safety and dignity of every human — which cannot be protected when decisions of civilizational consequence are made by systems and actors no government currently has the authority to constrain.
As AI capabilities are increasingly understood to rival — and plausibly exceed — the civilizational stakes of nuclear weapons, the Church is unlikely to carve out an exception for Thiel’s preferred vision of unchecked acceleration. If anything, the trajectory is the opposite.
The Thiel Thesis: Global Safety Institutions Are the Real Danger
In a series of lectures delivered to select audiences — at San Francisco’s Commonwealth Club in autumn 2024, in Paris, and most recently in Rome at the Palazzo Orsini Taverna, steps from Vatican City — Peter Thiel has been advancing a striking theological-political argument. The Antichrist, he contends, will not appear as a reckless technologist but as a safety-minded administrator. He will rise to power by exploiting existential fears — nuclear war, climate collapse, artificial intelligence — and offering a one-world governance system as the solution.[1]
In Thiel’s framework, figures who warn of AI risks and call for international oversight — from AI safety researcher Eliezer Yudkowsky to climate activist Greta Thunberg — are not merely misguided. They are, in his words, “legionnaires of the Antichrist.”[2] The slogan of the Antichrist, he has argued, is precisely “peace and safety” — a direct citation of 1 Thessalonians 5:3.[3]
Thiel does not deny the apocalyptic dangers of unchecked technology. In a 2024 Hoover Institution interview, he described a trilemma: Armageddon (runaway technological catastrophe), the Antichrist (a technocratic one-world state), and a narrow Third Way that somehow avoids both.[4] His implicit conclusion: any global institutional response to AI risk is more dangerous than the risk itself.
This is a coherent worldview. It deserves to be engaged seriously rather than dismissed. But it faces a structural problem that its author seems not to have fully reckoned with: it is in direct conflict with the most authoritative and consistently held body of Catholic Social Teaching on exactly this class of problem.
Why does this matter beyond theology? Because Thiel’s influence on US AI policy is arguably unmatched by any single private actor — and it operates primarily through people, not companies. Michael Kratsios, now Director of the Office of Science and Technology Policy, is a Thiel protégé who shaped technology policy in Trump’s first term. David Sacks, White House AI and Crypto Czar, moves in the same ideological orbit. Jacob Helberg, a senior State Department official now driving the administration’s AI geopolitics under the banner of “Pax Silica,” is a Palantir board member with close ties to Thiel’s network. These are not peripheral figures — they are the architects of US international AI posture at the precise moment that posture is being set. Beyond any single company, Thiel’s worldview is the water these officials swim in. His lectures on the Antichrist are not theological diversions — they are the ideological scaffolding for a US posture of maximal AI acceleration and minimal international constraint.
His reach extends further still into influential US Christian conservative circles — a constituency that matters enormously for any AI treaty coalition. Thiel is openly Catholic, intellectually shaped by the late philosopher René Girard, and has cultivated relationships across the intersection of faith, tech, and political power that few figures in American life can claim. For many in these circles — where distrust of globalism, the UN, and technocratic governance runs deep — his framing of world AI institutions as proto-Antichrist resonates intuitively. It gives theological permission to what is already a political instinct. Yet this is also where the Church has a unique and largely untapped capacity. No other institution can speak into these communities with comparable moral authority, cultural fluency, and doctrinal depth. The same people most exposed to Thiel’s counter-narrative are also the ones most likely to be moved by a serious, well-grounded papal statement on AI governance — one that takes their concerns about power and freedom seriously, rather than dismissing them.
The Church Has Already Answered This Question — on Nuclear Weapons
The parallel is not a rhetorical device. It is historical and doctrinal. Beginning in the early 1960s, the Catholic Church confronted precisely the dilemma Thiel describes — a technology of unprecedented destructive potential, geopolitical competition between great powers, and urgent calls for either deterrence-based stability or international control. Its response, developed across six decades and four pontificates, has been unambiguous.
In 1963, weeks after personally mediating between Kennedy and Khrushchev during the Cuban Missile Crisis, Pope John XXIII issued Pacem in Terris — the first encyclical addressed to “all people of good will,” not only Catholics. Its language on disarmament is unsparing:[5]
“Justice, right reason, and the recognition of man’s dignity cry out insistently for a cessation to the arms race. The stockpiles of armaments which have been built up in various countries must be reduced all round and simultaneously by the parties concerned. Nuclear weapons must be banned. A general agreement must be reached on a suitable disarmament program, with an effective system of mutual control.”
Crucially, the encyclical links disarmament to the need for a new kind of political authority — not because world government is desirable in the abstract, but because the problem is structurally global:[6]
“Today the universal common good poses problems of world-wide dimensions, which cannot be adequately tackled or solved except by the efforts of public authorities endowed with a wideness of powers, structure and means of the same proportions: that is, of public authorities which are in a position to operate in an effective manner on a world-wide basis.”
This was not a naive vision of world federalism. John XXIII was explicit that stability built on deterrence — the “balance of arms” — is not peace. It is fear. And fear, he argued, is no foundation at all.
Benedict XVI and the Explicit Link to Disarmament
Forty-six years later, a very different pope — Benedict XVI, the arch-conservative — made the linkage even more explicit. In his 2009 encyclical Caritas in Veritate, he listed the specific governance domains that require a world political authority, and disarmament is named alongside economic governance and the environment:[7]
“To manage the global economy… to bring about integral and timely disarmament, food security and peace; to guarantee the protection of the environment and to regulate migration: for all this, there is urgent need of a true world political authority.”
This is not a general aspiration. It is a programmatic claim: that certain categories of risk are structurally incapable of being managed by individual states, however powerful, and that the appropriate institutional response is an authority with real power — including, Benedict adds, with “real teeth.” The phrase is his, not a paraphrase.
Pope Francis, in his 2020 encyclical Fratelli Tutti, added an institutional dimension that maps precisely onto Thiel’s concern about weak states and transnational actors:[8]
“The twenty-first century is witnessing a weakening of the power of nation states, chiefly because the economic and financial sectors, being transnational, tend to prevail over the political. Given this situation, it is essential to devise stronger and more efficiently organized international institutions, with functionaries who are appointed fairly by agreement among national governments, and empowered to impose sanctions.”
And in April 2023, on the 60th anniversary of Pacem in Terris, Francis reaffirmed the nuclear framing with striking directness — writing for L’Espresso that “integral disarmament” remains the Church’s position, and that those who call it utopian are simply wrong: “It is not utopian, it is healthy realism.”[9]
Subsidiarity Is Not a Counter-Argument
Thiel’s implied response, and a common conservative Catholic objection, is subsidiarity: the principle that decisions should be made at the lowest competent level. This is indeed a foundational element of Catholic Social Teaching. But it does not do what the objection requires of it.
Subsidiarity is not an argument against supranational institutions per se. It is an argument against centralization when lower levels can adequately manage a problem. The entire point of the nuclear analogy — and why the Church invoked world authority specifically for disarmament — is that some risks are structurally incapable of being handled at the national level. No state can unilaterally verify that all other states have disarmed. No state can single-handedly prevent a rogue actor from deploying a weapon that destroys civilization. The appropriate level is therefore the global one, and subsidiarity logic itself demands this.
John XXIII made this precise argument in §137 of Pacem in Terris. The need for world authority follows from subsidiarity, not despite it. The same logic will apply, with even greater force, to advanced AI systems.
The AI Extension Is Coming
The Church has not arrived at this question unprepared. The Rome Call for AI Ethics, signed in 2020 by the Holy See alongside Microsoft, IBM, and later Amazon; the Pontifical Academy for Life’s sustained engagement with AI ethics; the Minerva Dialogues — an annual private gathering of leading tech figures and Vatican officials conceived and co-organized by Bishop Tighe at the Monastery of St. Mary Sopra Minerva — and Benanti’s Coexistence Appeal have together established the Church as one of the few institutions with credibility on both sides of the faith-technology divide. The question is whether that engagement will deepen to match the scale of the risk.
While Pope Leo XIV has made AI governance central to his papacy, a recent initiative by his leading AI advisor Paolo Benanti — in line with a 2024 New Year’s message by Pope Francis — has called for a bold AI treaty to ensure safety from immense potential safety harm and an ethical human future.[13]
The analogy between nuclear weapons and advanced AI is not a fringe position. It is shared by the leading AI safety researchers, by senior officials at Anthropic and OpenAI, and now increasingly by governments. The argument is structural: both technologies are capable of civilizational-scale harm, both exhibit dynamics that make unilateral national management inadequate, and both create collective action problems that can only be resolved through enforceable international agreement.
As the Church comes to understand — and it will, in months not years — that the safety risks of advanced AI are at minimum equivalent to those of nuclear weapons, the logical extension of its existing doctrine is not ambiguous. It will call for exactly what Thiel calls the Antichrist: strong, accountable, internationally structured governance of AI development and deployment.
The Deeper Problem with Thiel’s Argument
There is a further irony that deserves naming. Thiel warns against a global surveillance state — and runs Palantir, a company whose technology powers predictive policing, immigration databases, and military targeting systems across dozens of governments.[12] His proposed alternative to “Antichrist governance” is apparently unregulated AI acceleration under the stewardship of a small number of American technology companies — a concentration of power that, from the Church’s perspective, would seem more, not less, threatening to human dignity and subsidiarity.
Last March 18th, the post-humanist billionaire Peter Thiel concluded four days of lectures in Rome on AI and the Antichrist[14] (transcripts are unavailable, but leaked audio from earlier lectures in San Francisco, identical hand-outs, and extensive interviews establish his positions clearly) — warning that efforts to build an AI treaty to govern Artificial Superintelligence (ASI) risk producing global authoritarianism.
His core concern is well-founded, deeply shared by many well-meaning AI lab leaders — and deserves far more serious engagement than most treaty advocates have offered.
Yet his strategic analysis is partial and internally contradictory. He radically under-emphasizes the immense risks of not having a global treaty: human replacement or leading to the very Antichrist he claims to want to prevent. Furthermore, while at times he called for a third way that avoids both risks, he offered only obscure and underdeveloped hints at his vision for such a third way.[15]
While open to dialogue, we must be honest about the context. Thiel came to Rome to defend and “lock-in” the current hands-off and de-facto post-humanist US international AI policy — one he has arguably shaped more than anyone, and one that a growing number of voices inside and outside the administration are beginning to question.
He has framed his opposition to any global governance of AI in dramatic theological terms. It is good versus evil, where all those working towards a treaty are not merely mistaken but ill-intentioned[16] and constituting or abetting Antichrist.
His stated goal, in his own words,[17] is to prevent an ongoing alignment between Vance and Pope Leo XIV[18] that could produce a “Caesar-Papal” nexus catalyzing a US-backed AI treaty, and so abetting the “Antichrist.” Arguably, his ultimate fear is that this would act as a catalyst for other humans-first humanist US leaders[19] to follow.
Thiel mused publicly whether Trump himself might be the Antichrist, while also offering to ‘give a hearing’ to that argument.[1] Combined with his warning that the US could become ‘ground zero of the one-world state,’ this suggests Thiel fears Trump could abet the Antichrist he is warning about, should he decide to lead an AI treaty. Meanwhile, his unmatched power over US AI policy via his networks — at a time of aggressive AI nationalization and militarization — positions him as one of the most likely to become the Antichrist or usher it in.[20]
A debate is urgently needed. Thiel and his envoys are welcome. The outcome may turn out to be the most consequential in human history.
With these events, we aim to foster that debate — fairly and openly, but squarely on the side of a safe, fair, realistic and humans-first vision of the future.
Conclusion: A Doctrine Thiel Cannot Easily Undo
Catholic Social Teaching is not a set of opinions. It is a body of doctrine accumulated across multiple pontificates, consistently affirmed, and increasingly specific. The calls for international disarmament authority by John XXIII, Paul VI, Benedict XVI, and Francis are not incidental remarks. They are the considered positions of the Church’s highest teaching office, issued in response to the defining existential risks of each era.
Thiel is a gifted intellectual and his theological warnings deserve serious engagement. But the Catholic Church is an institution that, as Francis himself has said, “thinks in centuries.” Its doctrine on global institutions and disarmament did not develop in response to a trend. It developed in response to a category of risk — catastrophic, irreversible, globally distributed, and structurally beyond the capacity of any single nation to manage.
Advanced AI is that category of risk. What follows is our educated forecast, not a certainty: we believe the Church will recognize it as such, and that when it does, the accumulated doctrine points unambiguously toward strong, accountable, internationally structured governance of AI.
A word of epistemic honesty is warranted. Popes retain full magisterial authority to develop and reframe Catholic Social Teaching, and Pope Leo XIV has not yet issued a major encyclical on AI or dangerous technologies. We hope he will — and that when he does, he will confirm and deepen the calls of his predecessors for strong global governance of AI and other civilizational-scale risks. Given the growing vacuum in global soft power and the accelerating pace of AI development, there is an argument that the Church should consider taking a more active guiding role than it has on previous technological dangers — not merely affirming the need for international institutions, but helping to define what legitimate, human-dignity-centered governance of AI should look like.
We also hope that such a statement will engage seriously with the substantive concern — distinct from its theological framing — that many powerful and well-intentioned AI decision-makers genuinely share: namely, that poorly designed global institutions for AI could inadvertently concentrate power, suppress dissent, or produce authoritarian outcomes at scale. This is not a fringe fear. It deserves a serious institutional answer, not dismissal. The Church’s own tradition — with its insistence on subsidiarity, human dignity, and accountability at every level — is arguably better equipped than any secular framework to provide that answer. An encyclical that names this risk directly, and offers principled criteria for what global AI governance must never become, would do more than affirm the need for international institutions. It would help build the moral architecture that makes those institutions trustworthy.
There is already a vehicle for this. The Minerva Dialogues — the annual closed-door forum co-organized by Bishop Tighe that has quietly brought together Silicon Valley leaders, Vatican officials, and independent thinkers under Chatham House rules since 2016[21] — represent precisely the kind of trusted, neutral space in which a humans-first humanist alliance could begin to take shape. Expanded deliberately to include key potential influencers of Trump’s AI policy alongside Church leadership, the Minerva Dialogues could serve as the Vatican’s most credible vehicle for facilitating the kind of frank, off-the-record dialogue that is impossible in any governmental or corporate setting. CBPAI’s Rome Convening on June 18–19, 2026 is conceived in the same spirit — a complementary forum where this conversation can begin in earnest.
What we can say with confidence today is that six decades of consistent doctrine do not reverse easily, and the structural logic that drove the Church to call for international disarmament authority — that some risks are simply beyond the competence of any single state — applies with at least equal force to advanced AI. The doctrine is already there, patient and accumulated.
The question is whether the Church’s voice will reach the right people in time — not as a political actor lobbying for a treaty, but as the one institution with the moral authority, the global reach, and the centuries of credibility to offer what no think tank or government can: a framework for what humanity must demand of AI governance, and what it must never permit. The specific individuals shaping Trump’s AI policy right now — embedded in networks where Catholic Social Teaching carries weight and where the framing of technology as a moral question is taken seriously — are reachable. The window for The Deal of the Century is narrow. It will not stay open indefinitely.
