Pope Leo XIV’s first encyclical, Magnifica Humanitas, frames artificial intelligence as a transformative force that demands moral guidance rooted in Catholic social teaching. Unveiled on 25 May 2026, the document warns that AI’s societal impact could exceed that of the Industrial Revolution and calls for the technology to be placed at the service of human dignity, the common good, and global solidarity 1 2 3 4.
The encyclical was presented in the Vatican’s Synod Hall, where Pope Leo XIV personally attended—a rare gesture that drew sustained applause from the Roman Curia, academic representatives, and diplomats 2 3. Among the speakers was Christopher Olah, co‑founder of the AI research firm Anthropic, whose presence the pope highlighted as a sign of hope for dialogue across differing perspectives 2 4. The pope signed the document on 15 May, echoing the historic date of Leo XIII’s Rerum Novarum (1891) 2.
U.S. bishops praised the encyclical as “crystal‑clear guidance” for the AI era, emphasizing its reminder that technology cannot replace a child of God 1. Archbishop Paul Coakley called it a powerful reminder of human dignity, while Archbishop Nelson Pérez highlighted the need to navigate AI’s moral pitfalls 1. Bishop Michael Burbidge and Bishop Michael Martin echoed the call to read the document carefully and noted its parallels with the Church’s response to past industrial changes 1. Mexican bishops and Ukrainian Metropolitan Archbishop Borys Gudziak described the text as offering a hopeful, doctrinally grounded path for safeguarding humanity 1.
In his Vatican speech, Olah urged “global moral oversight” of AI, identifying three immediate challenges 4:
Olah emphasized the need for “informed critics” and “moral voices” outside commercial incentives to guide AI development responsibly 4. He called for an alliance among policymakers, educators, and families to support adults and children navigating the AI landscape 4.
The presentation featured three senior cardinals—Secretary of State Pietro Parolin, Cardinal Víctor Manuel Fernández (Dicastery for the Doctrine of the Faith), and Cardinal Michael Czerny, SJ (Dicastery for Promoting Integral Human Development)—as well as theologians Anna Rowlands and Leocadie Lushombo, who contributed scholarly perspectives on social teaching and political theology 2 3.
The encyclical calls for continued dialogue between the Church, scientific community, and civil society to “listen, discern, and act” on AI’s ethical challenges 2 4. By invoking the Church’s historic role in nuclear disarmament, Pope Leo XIV frames AI governance as a moral imperative that must be accompanied by public control and a commitment to the universal human family 2 3.*
How should the Church safeguard human dignity amid AI’s transformative impact?
Human dignity can be safeguarded in the age of AI when the Church’s anthropology and Social Doctrine become the criteria for judging and governing technology: the human person is never reducible to data or a commodity, and digital power must be oriented toward the common good, with special protection for the vulnerable.
AI will always increase human power, but Pope Leo XIV warns that when “technology becomes the ultimate criterion, the human person risks being reduced to data, a cog in a machine or a commodity.”
That risk is not merely technical; it is anthropological and moral. The Church teaches that dignity is inherent and unconditional, because every person is created in God’s image and therefore has a dignity that “cannot be lost.”
Benedict XVI likewise rejects a purely materialistic view of human life: knowledge and love include dimensions “over and above” what material instruments can explain, and authentic development requires a “spiritual dimension” that technology cannot supply by itself.
Implication for AI: safeguarding dignity means defending the priority of the human person—especially conscience, freedom, and moral discernment—as the guiding horizon for design, deployment, and regulation, so that AI remains an instrument rather than a replacement for human responsibility.
Key sources: Dignitas Infinita; Magnifica Humanitas (Leo XIV); Caritas in Veritate (Benedict XVI).
Faced with “this concentration of power in the digital world,” Pope Leo XIV identifies the criteria of judgment as the “noble principles of Social Doctrine”: inalienable dignity of the human person, common good, universal destination of goods, subsidiarity, solidarity, and social justice.
He then connects those principles to specifically AI-relevant questions: whether digital infrastructures and algorithms:
This is crucial: dignity is not safeguarded only by protecting individuals from harm in the narrow sense, but also by ensuring that AI does not become a tool of exclusion, domination, or unfair distribution of opportunities—since that would conflict with social justice and the common good.
Implication for AI: the Church’s approach favors governance and discernment rather than technological determinism: decisions about AI should be continuously measured against dignity-centered social principles, not against efficiency alone.
Key sources: Magnifica Humanitas (Leo XIV), para. 96; para. 180 (technology vs. dignity).
John Paul II teaches that technology should remain man’s ally, but it can become his enemy when it “supplants” him and reduces him to slavery to the machine.
He also insists on “the primacy of man in the production process,” where instruments—including the modern means of production—are “only a mere instrument subordinate to human labour,” because man alone is a person.
Implication for AI in work: dignity is safeguarded when AI does not remove human agency, creativity, responsibility, or stable access to just work, but instead supports human flourishing and the human subjecthood of labor.
Benedict XVI argues that social communications “are so integral a part of life today” that it is “absurd” to say they are neutral; their meaning and purpose must be sought within an anthropological perspective oriented toward universal values.
He stresses that the media can promote freedom and development only when they focus on “promoting the dignity of persons and peoples,” being “clearly inspired by charity and placed at the service of truth, of the good,” and fraternity.
Implication for AI media systems (feeds, recommendations, persuasion): safeguarding dignity requires moral direction toward truth and the good, not merely optimization of engagement.
Pope Leo XIV directly applies these principles to AI and healthcare. He warns that because digital technology shapes how people think and relate—sometimes to the point of “forgetting how to recognize and cherish all that is truly human”—the priority must remain human dignity and the common good.
He emphasizes the “irreplaceable nature of human relationships” in healthcare: medical professionalism “can never be reduced merely to solving a problem,” and technological devices must “never detract from the personal relationship between patients and healthcare providers.”
He also recalls the ontological dignity of the person and the vocation/responsibility of healthcare professionals as “guardians and servants of human life,” especially in vulnerable stages—extending that same requirement to those responsible for AI in healthcare.
Implication for AI-assisted medicine: AI should support care, but dignity is safeguarded by preserving human closeness, communication, and responsibility—particularly where vulnerability is highest.
Dignitas Infinita explicitly condemns forms of harm including “digital violence,” and it calls for states, societies, and individuals to protect and promote dignity—especially for the vulnerable.
Implication for AI: systems must be assessed for their effects on persons who are most at risk of exploitation, abuse, marginalization, or coercion in digital environments.

Within the limits of these sources, the Church’s safeguarding logic implies commitments such as:
To safeguard human dignity amid AI’s transformative impact, the Church urges that digital power be continually judged by the primacy of the human person—so that AI fosters participation, protects the vulnerable, ensures fair access, preserves personal relationships where care is needed, and never becomes an ultimate criterion that reduces the person to data or a commodity.
