The Catholic case for AI governance is not simply that artificial intelligence should be made safer or more efficient. It is that law and public policy must ensure AI serves people and the common good, rather than treating people as data points, widening unjust inequalities, or displacing human judgment. On that measure, the call for law to govern AI and address inequality is closely aligned with the principles articulated in Antiqua et Nova and Pope Leo XIV’s Magnifica Humanitas. 1 2

Human dignity is the governing standard

Catholic teaching treats human dignity as inherent: a person’s worth does not depend on productivity, social status, a risk score, or how accurately an algorithm can classify them. Accordingly, AI should be evaluated not only by whether it works as designed, but by whether its purposes, methods, and broader effects respect human dignity and promote the common good. Responsibility for directing technology toward those ends belongs across society, including to developers, operators, users, and regulators. 1 3

That standard changes the question policymakers should ask. It is not enough to ask whether an AI system is innovative or economically useful. They must also ask who benefits, who bears its risks, and whether it supports people’s freedom and ability to participate in society. Pope Leo XIV cautions that AI should be “a tool for the good of human beings, not to diminish them, not to replace them.” 4

Justice includes how AI distributes power and opportunity

A central concern is that AI may intensify existing inequalities—not only disparities in wealth, but also differences in access to social and political influence. Pope Francis warned that digital technologies can deepen such inequalities and called for technological progress to be accompanied by greater equality and social inclusion. 5

Pope Leo XIV gives this concern practical policy expression: when algorithms affect access to credit, jobs, services, or opportunities, decisions should be understandable, open to challenge, and subject to oversight. He also identifies inclusion and access—such as investment in skills, infrastructure, and essential services—and measures to correct imbalances in wealth and power as criteria for an economy that favors human dignity. 2

This implies that “fairness” cannot be reduced to checking whether a model produces similar outputs for different groups. Governance must also consider the system’s wider social effects: whether it excludes people from essential opportunities, concentrates power, or leaves disadvantaged communities without meaningful access to AI’s benefits. The Rome Call for AI Ethics likewise insists that AI should include everyone, discriminate against no one, and avoid exploiting vulnerable people. 6

Accountability must preserve human judgment

A system can produce a technically consistent result and still make an unjust decision. Data may reflect social prejudice, and a person’s past behavior may not fairly determine their future prospects. Antiqua et Nova warns against allowing algorithmic evaluations to reduce a person to a profile or deny them the possibility of changing, growing, and contributing. 7

That is why transparency, contestability, and oversight are not merely technical refinements. They help ensure that people can understand when AI has shaped a consequential decision and can seek review rather than being left subject to an opaque classification. Leo XIV specifically calls for decisions influenced by data and algorithms to be understandable and contestable, and for them to be overseen so that individuals are not reduced to mere profiles. 2

Human oversight, however, must be substantive. If officials simply accept an algorithm’s conclusion without examining its basis or effects, formal human involvement does little to protect dignity. The deeper principle is that AI must remain directed by human intelligence and judgment, rather than becoming an authority that people feel unable to question. 8 9

Law should guide innovation toward the common good

Catholic teaching does not equate regulation with hostility to technology. It calls for technological development to be directed toward authentic human goods, with the ends and means of each application assessed for their effects on dignity and the common good. Leo XIV describes safeguards for transparency, inclusion, and equity not as a curb on innovation, but as conditions that make innovation “civilized and humane.” 1 2

This also places responsibility beyond individual users. AI systems are developed, deployed, and governed within institutions and markets, so ethical responsibility extends across those involved in their design and use. Antiqua et Nova says that this responsibility belongs at every level of society and should be guided by subsidiarity—the principle that decisions should be made at the appropriate level, while higher levels act where coordination or protection is needed. 1

The practical implication is a need for governance that can scrutinize high-impact uses, require accountability, and address harms that individuals cannot remedy alone. The supplied Catholic texts support these principles, though they do not prescribe one complete regulatory framework or specify particular statutory provisions.

The measure of success

From a Catholic perspective, the success of AI governance is not measured solely by economic growth, speed, or technical capability. It is measured by whether technology serves people, protects their dignity and freedom, and contributes to a more inclusive and just society. The claim that AI governance must prioritize human dignity and justice is therefore not an optional ethical addition to innovation: it is a standard for deciding what kinds of innovation should be encouraged, how they should be used, and what safeguards they require. 3 6 8
