Pope Leo XIV Leads the Vatican’s Ethical Push on Artificial Intelligence
5/17/2026, 1:27:22 AM
Historical Context and Prior Vatican Initiatives
The Vatican first entered the AI debate with the Rome Call for AI Ethics in February 2020, a pledge signed by tech firms such as Microsoft and Cisco (later reports added IBM). The document urged transparency, inclusion, accountability, impartiality, reliability, security and privacy. Pope Francis later called for an international treaty on AI, warning that technologies lacking “compassion, mercy, morality and forgiveness” could threaten humanity.
Key Documents and Declarations
- Antiqua et Nova (Jan 2025, ~30 pages) – Pope Leo XIV’s first substantive AI guidance, contrasting human relational truth-seeking with pattern-recognizing machines.
- Quo Vadis, Humanitas (Mar 2026) – International Theological Commission report chaired by Cardinal Víctor Manuel Fernández, warning that detached algorithmic knowledge threatens the “true good of humanity.”
- Upcoming Encyclical (expected summer 2026) – Anticipated to embed AI concerns within the Church’s social teaching on dignity, justice and labor.
- Study Group on AI (May 2026) – Created by Pope Leo XIV to examine AI’s effects on humanity and to shape the encyclical’s ethical framework.

Data & Statistics
- The Catholic Church counts ?1.5 billion adherents worldwide, a demographic the Vatican cites as a reason to shape AI policy.
- The Rome Call initially listed Microsoft and Cisco; later reports added IBM as a signatory.
- Vatican statements highlight the “vast amounts of energy and water” required by AI data centers.
Why It Matters: Human Dignity, Labor, and Peace
Vatican officials argue that AI must serve the “intrinsic dignity of every human being,” protect children from manipulative algorithms, and avoid replacing human judgment in warfare. Pope Leo XIV links AI’s unchecked deployment to “inhuman evolution” of conflict in Ukraine, Gaza, Lebanon and Iran, urging human-centric control over lethal autonomous weapons.
Official Statements & Responses
- Pope Leo XIV told the College of Cardinals that AI poses “new challenges for the defense of human dignity, justice and labor.”
- In a June 2025 address to political leaders, he asserted that “our personal life has greater value than any algorithm.”
- At the AI for Good Summit, he emphasized that AI “cannot replicate moral discernment or the ability to form genuine relationships.”
- Speaking to youth in Indianapolis, he warned that AI “cannot replace human intelligence” nor “judge between what is truly right and wrong.”
- In December 2025 he described faces and voices as “sacred” and cautioned against surrendering judgment to engagement-maximizing algorithms.
- At La Sapienza University, he described the AI-driven war landscape as a “spiral of annihilation.”
Criticism & Opposition
The Trump administration, represented by President Donald Trump’s 2024-25 AI-focused China visit, has rejected multilateral AI regulatory efforts and removed domestic barriers to rapid AI development, directly contrasting the Vatican’s call for ethical constraints and a ban on lethal autonomous weapons.
Conflicting Reports & Gaps
- Signatory list: The Rome Call is reported as signed by Microsoft and Cisco in one source, while another adds IBM, indicating inconsistent documentation.
- Encyclical release date: Sources vary between “coming weeks” (May 2026) and “expected in the coming weeks” without a precise date, leaving the timeline uncertain.
Verbatim Quotes
- “In our own day, the Church offers to everyone the treasury of her social teaching in response to another industrial revolution and to developments in the field of artificial intelligence that pose new challenges for the defense of human dignity, justice and labor.” — Pope Leo XIV, address to the College of Cardinals (May 2025)
- “our personal life has greater value than any algorithm, and social relationships require spaces for development that far transcend the limited patterns that any soulless machine can pre-package.” — Pope Leo XIV, address to political leaders (June 2025)
- “While AI can simulate aspects of human reasoning and perform specific tasks with incredible speed and efficiency, it cannot replicate moral discernment or the ability to form genuine relationships.” — Pope Leo XIV, AI for Good Summit (July 2025)
- “Children and adolescents are particularly vulnerable to manipulation through AI algorithms that can influence their decisions and preferences. It is essential that parents and educators be aware of these dynamics, and that tools be developed to monitor and guide young people’s interactions with technology,” — Pope Leo XIV, conference on the dignity of children (Nov 2025)
- “Our faces and voices are unique, distinctive features of every person. … Faces and voices are sacred,” — Pope Leo XIV, December 2025 youth conference
What’s Next
The Vatican’s AI study group will draft the forthcoming encyclical, expected in summer 2026, which will likely codify the Church’s stance on AI governance, environmental impact, and the prohibition of lethal autonomous weapons. Ongoing dialogues with tech firms, governments, and international bodies suggest the Vatican aims to embed its ethical framework into global AI policy discussions.
