Pope Leo XIV and Pope Francis on AI

The foundation Francis built

Pope Francis's engagement with AI developed across multiple documents and venues over more than a decade. Four are foundational for understanding what Leo XIV inherits.

Laudato Si' (May 2015). Francis's environmental encyclical introduced the “technocratic paradigm” (paragraphs 106-114) as a diagnostic concept. The paradigm is the disposition that treats all problems as solvable by technical means, all values as quantifiable, and all relationships as subject to instrumental rationality. Laudato Si' applied the concept primarily to environmental degradation, but the framework was always broader. It is the framework Magnifica Humanitas uses in Chapter 3 to read AI specifically. The Francis-Leo XIV continuity begins here.

Fratelli Tutti (October 2020). Francis's social encyclical extended the diagnosis to social fragmentation, throwaway culture, and what he called the “dark clouds” over a closed world. The encyclical also addressed digital communication directly (paragraphs 42-50), warning about the dynamics of digital aggression, the loss of authentic encounter, and the “closed worlds” that algorithmic curation produces. These themes return throughout Magnifica Humanitas, especially in Chapter 4's treatment of truth, attention economy, and digital communication. The connection is explicit: Leo XIV cites Fratelli Tutti multiple times in Magnifica Humanitas.

The G7 address at Borgo Egnazia (June 14, 2024). Francis became the first pope to address a G7 summit. The address focused on AI specifically and made several claims that Magnifica Humanitas develops at length. Francis distinguished human intelligence from machine intelligence, warning against the “techno-human paradigm” that flattens the difference. He called for AI in lethal autonomous weapons systems to be banned. He named AI's effects on work, employment, and the social order. The address closed with a striking image: humans must keep their “hand on the joystick.” Leo XIV cites the G7 address directly in his June 2025 message to the Second Annual Conference on AI, and the same arguments are developed throughout Magnifica Humanitas.

Antiqua et Nova (January 2025). The doctrinal note issued by the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education was the Vatican's first major doctrinal text dedicated to AI. Approved by Francis and released about three months before his death, it established philosophical foundations on the relationship between human and artificial intelligence, the dignity of the person, the limits of computational reason, the ethics of AI in healthcare, education, warfare, labor, and disinformation. Antiqua et Nova is the doctrinal foundation on which Magnifica Humanitas builds. Leo XIV cites it throughout. The two documents are designed to function together. For the detailed treatment of how Magnifica Humanitas develops what Antiqua et Nova began, see Antiqua et Nova Explained.

Beyond these four, Francis addressed AI in his 2024 World Day of Peace message (the first papal message dedicated to the topic), in multiple addresses to the Pontifical Academy for Life and to the Minerva Dialogues, and in the development of an “ethics of the algorithm” through the Vatican's Rome Call for AI Ethics. The body of Francis-era teaching on AI is substantial. Magnifica Humanitas inherits all of it.

What Leo XIV continues from Francis

The continuity is broader than press coverage will typically convey. Five major continuities are worth naming.

The technocratic paradigm as diagnostic concept. Chapter 3 of Magnifica Humanitas uses the technocratic paradigm as its central analytical category for understanding what is wrong with current AI development trajectories. The framework is Francis's. Leo XIV extends it; he does not depart from it.

The priority of the relational and contemplative over the efficient. Francis's persistent claim that the deepest human goods are not the kinds of things efficiency-oriented systems can produce or even recognize runs throughout Magnifica Humanitas. The encyclical's emphasis on relationship, contemplation, slowness, and what cannot be quantified is recognizably Francis-shaped.

The categorical position against AI in lethal autonomous decisions. Francis's G7 address called for a ban on lethal autonomous weapons. Antiqua et Nova echoed the position. Magnifica Humanitas paragraph 198 makes it magisterial: “No algorithm can make war morally acceptable.” The sharpness is new but the substance is continuous.

The concern for workers and the displaced. Francis's teaching on the dignity of work, the warning against unemployment that excludes people from social participation, and the call for technology to serve rather than displace human labor are all present in Magnifica Humanitas. Chapter 4 develops them at length.

Integral ecology. Francis's claim that environmental, social, and technological questions are inseparable, that the same disposition produces ecological degradation and social marginalization and technological dehumanization, runs throughout Magnifica Humanitas. The phrase “ecological in the deepest sense” in paragraph 110 (on disarming AI) is a Francis-era formulation extended into a new domain.

These five continuities are substantive. Anyone arguing that Magnifica Humanitas “breaks from Francis” on AI has not read either pope carefully. The framework, the categories, the moral urgency, and the priority of the human are all continuous. Leo XIV inherits Francis's AI teaching and develops it.

What Leo XIV extends

Continuity is not identity. Magnifica Humanitas develops Francis's framework substantially in three ways.

Magisterial form. Francis's AI teaching, despite its volume, never took the form of a pope-authored encyclical specifically dedicated to AI. The teaching was distributed across encyclicals on related topics (Laudato Si', Fratelli Tutti), addresses, messages, and a dicasterial doctrinal note (Antiqua et Nova). Leo XIV's choice to make a dedicated AI encyclical his first encyclical signals that the moment requires consolidation at the encyclical level. The magisterial weight is different. Encyclicals carry institutional and doctrinal authority that addresses and messages do not. Magnifica Humanitas consolidates and elevates Francis-era teaching.

Systematic structure. Francis's teaching on AI developed across multiple venues and was therefore necessarily fragmented. Magnifica Humanitas assembles the Francis-era material into a single coherent structure, organized around the Babel and Nehemiah frame in five chapters with a clear progression from foundations through AI ethics through truth and work through war. The systematic character is new. The substance is continuous.

Direct engagement with industry and policy. Francis's framing tended toward the pastoral and the prophetic. He named the dangers, called for moral seriousness, addressed pastoral concerns about loneliness and dehumanization. Magnifica Humanitas retains the pastoral and prophetic registers but adds direct engagement with industry actors (paragraph 111's address to AI developers), with policy mechanisms (paragraph 106's call for “robust legal frameworks, independent oversight”), with supply chains (paragraph 179's call for transparency and due diligence), and with the international order (paragraph 200's call for an international framework on autonomous weapons). The operational specificity is new. The moral framework is continuous.

The Anthropic presence at the Vatican launch event is consistent with this extension. Francis engaged the AI industry through the Rome Call for AI Ethics framework but did not share a stage with a frontier-lab co-founder at a magisterial document release. Leo XIV did. The shift is in posture and access, not in position.

The four original contributions

Four moves Magnifica Humanitas makes have no precedent in Francis-era teaching. These are not extensions of Francis; they are additions to the developing magisterial tradition.

The Babel and Nehemiah biblical frame. The opening of Magnifica Humanitas introduces two biblical scenes as the structural organization of the entire encyclical: the Tower of Babel as the failed building project that “chose homogenization over communion,” and Nehemiah's rebuilding of Jerusalem's walls as the alternative that distributed the work, listened to the community, and proceeded by subsidiarist coordination. The frame returns throughout the document and closes the conclusion. Francis used biblical imagery extensively, but he did not use the Babel and Nehemiah pairing as a structural frame for AI specifically. This is a Leo XIV move. The Nehemiah figure in particular, with its emphasis on distributed and consultative response rather than top-down imposition, is the encyclical's distinctive contribution to Catholic thinking on how to engage civilizational challenges. See Magnifica Humanitas: What Was Surprising for further treatment of the frame.

The phrase “disarming AI” (paragraph 110). Pope Leo XIV's original contribution to the Catholic vocabulary on AI. Francis used “ethics of the algorithm” and the Rome Call framework; he did not use “disarming AI.” The phrase extends the Church's nuclear-disarmament tradition into the AI domain and does work that “AI safety,” “AI alignment,” and “AI ethics” cannot do, by naming the competitive race dynamics of AI development as themselves part of what has to change. For the full reference, see Disarming AI: The Phrase, the Concept, and What It Asks.

The papal apology for the Church's role in legitimizing slavery (paragraphs 175-176). John Paul II issued broad requests for forgiveness during the Jubilee of 2000, and Francis spoke about colonialism in Bolivia in 2015 and addressed Christian involvement in the trans-Atlantic slave trade. No previous pope, however, has formally apologized for the role past popes themselves played in legitimizing slavery through specific magisterial documents. Magnifica Humanitas names the bulls by date (Sicut Dudum 1435, Etsi Suscepti 1442, Dum Diversas 1452, Romanus Pontifex 1455) and issues the apology in the pope's own voice: “For this, in the name of the Church, I sincerely ask for pardon.” This is unprecedented in its specificity. For the full treatment, see New Forms of Slavery.

The direct address to AI developers (paragraph 111). Francis addressed AI broadly and addressed the actors of the AI industry through the Rome Call framework, but he did not direct a specific magisterial appeal to AI developers as a professional class in the way Magnifica Humanitas does in paragraph 111. The framing of development as “human participation in the divine act of creation” with corresponding “ethical and spiritual responsibility” is new. The vocation framing of AI development as such is new. For the audience-scoped reading, see Magnifica Humanitas for Developers.

These four moves explain why Magnifica Humanitas reads as a document with its own voice rather than as a consolidation of existing teaching. Francis built the foundation. Leo XIV adds four things Francis did not have, in the time he did not have, the inclinations to add, or both.

A note on register and pastoral style

Beyond doctrinal substance, the two popes sound different. The difference is style, not substance, but it matters for how the documents land.

Francis's register on AI was characteristically Francis: prophetic, pastoral, attentive to the marginalized, deploying striking images (“hand on the joystick,” “throwaway culture,” “the bishops' visit to the periphery”), often improvisational, often willing to push past careful theological framing to make a pastoral or prophetic point. The register is part of what made Francis effective. It was also part of what frustrated some Catholic readers who preferred more systematic theological development.

Leo XIV's register in Magnifica Humanitas is different. The encyclical is more systematic. The structure is more carefully laid out. The theological development is more visible, particularly in the Augustinian frame at paragraph 130. The register matches Leo XIV's biographical formation: Augustinian friar, doctorate in canon law, two decades of administrative leadership in the order and then in the Roman curia. The Pope is engaging the AI question with the analytical tools his formation gave him.

For Catholic readers and observers, this register matters because it signals continuity with the Catholic theological tradition in a particular way. Francis's prophetic register sometimes raised concerns among readers attached to systematic theological method. Leo XIV's analytical register reassures those readers without requiring any departure from Francis's substantive positions. The diplomatic effect is real, even if it is not the document's primary purpose.

For non-Catholic audiences, the register difference will be visible in citation patterns. Francis's AI teaching produced quotable lines that journalists and ethicists reach for. Magnifica Humanitas will produce different kinds of citations: structural arguments rather than vivid images, paragraph-anchored claims rather than memorable phrases (with the exception of “disarming AI” and “no algorithm can make war morally acceptable”). The two will function together in the longer reception. Francis's lines have rhetorical force; Leo XIV's structure has analytical reach.

What this means for how to read both pontificates on AI

Three practical implications follow from the continuity-and-development analysis.

Read them together, not in isolation. Magnifica Humanitas assumes the reader has at least basic familiarity with Laudato Si', Fratelli Tutti, and Antiqua et Nova. The technocratic paradigm, integral ecology, throwaway culture, and the foundational philosophical positions are not re-argued. They are deployed. Readers coming to Magnifica Humanitas without that background will follow the surface argument but miss the depth at which Leo XIV is engaging Francis-era teaching.

Pay attention to what is genuinely new. The four original contributions (Babel/Nehemiah frame, “disarming AI,” slavery apology, address to developers) are the parts of the document that did not exist before and that Leo XIV's papacy is adding to the magisterial tradition. These are where the new pope's voice is most distinct, and they are likely to be the most heavily cited parts of Magnifica Humanitas in the years ahead.

Resist the press framings. Both “Leo XIV breaks from Francis on AI” and “Leo XIV is just continuing Francis on AI” are misreadings, in opposite directions. The more accurate framing is that Magnifica Humanitas consolidates and elevates the Francis-era foundation while making specific original contributions that the moment required. This is how Catholic magisterial development typically works. The two papacies are doing different things at different moments in the same developing tradition.

Where this sits in the developing magisterial tradition

Catholic social teaching has a tradition of papal-to-papal development that Magnifica Humanitas sits inside. Pope Leo XIII's Rerum Novarum (1891) established the modern Catholic social teaching framework on labor and capital. Pope Pius XI's Quadragesimo Anno (1931, the fortieth anniversary of Rerum Novarum) developed it in light of the Great Depression and the rise of totalitarian movements. Pope John XXIII's Mater et Magistra (1961, the seventieth anniversary) extended it to the conditions of post-war development. Pope John Paul II's Laborem Exercens (1981) reframed work theologically. Each pope built on his predecessors. Each pope made his own contributions. None merely repeated.

Magnifica Humanitas is the next move in this tradition, applied to AI. Pope Leo XIV's name choice was deliberate: the document opens by naming the 135th anniversary of Rerum Novarum and presents itself as the AI-era counterpart. The continuity with Francis is one layer of the continuity the document is operating in; the broader continuity is the entire arc of modern Catholic social teaching from Leo XIII forward.

Readers who notice this longer arc will see the document differently than readers who frame it primarily as a Francis-or-not-Francis question. The Francis comparison is real and matters. It is not the only frame that matters.
