Pope Leo XIV Declares AI Is Not 'Morally Neutral' — Inside the Warnings of His Historic Encyclical 'Magnifica Humanitas'

The X Post and the Encyclical: One Argument, Two Audiences

The June 25 post condensed a central argument that runs through the entire encyclical. Published on May 25, 2026, and signed on the 135th anniversary of Pope Leo XIII's Rerum Novarum, Magnifica Humanitas argues from paragraph 9 that "technology is never neutral, because it takes on the characteristics of those who devise, finance, regulate, and use it" . The encyclical insists that ethical scrutiny must extend beyond use-case to the very design, ownership, and governance of AI systems . The Pope's social media post simply brought that argument to a broader digital audience .

Specific Ethical Demands and Warnings in 'Magnifica Humanitas'

The document runs approximately 38,000–42,000 words across 245 paragraphs and five chapters, making it the first papal encyclical entirely dedicated to artificial intelligence . Its key demands and warnings include:

'AI Must Be Disarmed'

The central command of the encyclical, stated in paragraph 125, calls for freeing AI from "frameworks that transform it into an instrument of control, exclusion, and destruction" . This is defined not as rejecting technology but as stripping it of logics of domination .

AI as 'Digital Colonialism'

The Pope warns that concentrated corporate and state control of AI reduces human beings to data points to be extracted and exploited, mirroring colonial dynamics. He calls this an "unprecedented form of colonialism" .

Machines Cannot Be Moral Agents

The encyclical warns against attributing consciousness, moral responsibility, or personhood to AI, insisting that accountability must always remain with human actors .

Rejection of Transhumanism and Posthumanism

It warns that AI-driven efforts to "optimise" human beings risk eroding the inherent dignity of the person .

Demand for Shared Standards of Social Justice

The encyclical calls on developers and governments to implement "shared standards of social justice" so that AI respects human dignity and serves the common good, not private profit .

An 'Educational Alliance'

It advances a concept of cooperation among families, schools, and civil society to defend the school as a formative community and to combat the commercial exploitation of children's attention through algorithmic systems .

Warning on 'Algorithmic Governance'

The document demands scrutiny of the hidden value systems coded into AI, arguing that design choices express a vision of the human person that often prioritizes efficiency over communion .
