Catholic teaching treats AI not as a morally neutral instrument, but as a technology whose design and use inevitably expresses a vision of the human person and society—so human dignity and the common good must set the ethical terms of AI development and governance. 1 2 3

Human dignity as the controlling norm for AI ethics

Catholic Social Doctrine grounds the evaluation of technology in the inalienable dignity of the human person and in institutions ordered to the common good. The Catechism teaches that “the dignity of the human person requires the pursuit of the common good” and that everyone should help create and support institutions that improve human life. 4

It also clarifies that respect for persons means respecting fundamental rights flowing from that dignity: the other is “another self,” and this presupposes respect for the person’s fundamental rights. 5

AI ethics, therefore, cannot be reduced to whether a tool is efficient or “useful.” If an AI system’s operation (or even its underlying design) undermines human rights—especially by treating some lives as less worthy—it contradicts dignity at the level of the system’s practical criteria. Pope Leo XIV explicitly draws this line: an AI system is not morally neutral; it can introduce criteria that “contradict the inalienable dignity of the human person” if it excludes people “without the possibility of appeal.” 1

Catholic teaching also connects dignity to social justice and equality of persons. The Catechism holds that equal dignity requires efforts to reduce excessive social and economic inequalities. 6 And it states that social justice is obtained only by respecting the transcendent dignity of man, emphasizing that the defense and promotion of dignity have been entrusted to us by the Creator. 7

AI is not morally neutral: design choices embed values

A central Catholic claim about AI ethics is that the technology cannot be treated as value-free. Pope Leo XIV explains: “we cannot consider AI to be morally neutral,” because “every technical tool embodies choices and priorities” through what it measures, ignores, optimizes, and how it classifies people and situations. 1

This is crucial for human dignity: even if an AI is intended for “good purposes,” the moral question includes how the system is built and what vision of persons is embedded in its data and models. The pope says ethical discernment must examine not only intended use but “how that system is designed and what vision of the human person and society is embedded” in the data and models guiding it. 1

Catholic teaching also prevents a category error: equating machine “intelligence” with human moral agency. Pope Leo XIV states that AI must not be equated with human intelligence; such systems imitate functions of human intelligence, and crucially lack moral conscience—“they do not judge good and evil… or bear responsibility for consequences.” 8

This matters ethically because it reinforces a duty of accountability: responsibility cannot be dissolved into “the machine decided.” If AI lacks conscience, humans must remain responsible for the moral and social outcomes produced through AI systems. 8 9

Governance and rights-protection: prudence, oversight, and risk evaluation

Catholic teaching supports progress, but insists on prudence, rigorous evaluation, and legal safeguards. Pope Leo XIV calls for “prudence, rigorous evaluation and even, at times, a slower pace” in adopting AI, describing it as “responsible care for the human family.” 10

He links the need for governance to an imbalance between rapid technological growth and slower development of norms and institutions capable of governing AI’s effects. He warns that if robust frameworks and independent oversight are absent, change will be driven by “technocratic thinking,” shaped by those who control data, infrastructure, and computing power. 10

A practical implication follows: AI ethics must be implemented through institutions—not merely through abstract principles. Pope Leo XIV explicitly requires “robust legal frameworks, independent oversight, informed users and a political system that does not abdicate its responsibility.” 10

The COMECE statement on the EU Artificial Intelligence Act mirrors this: it welcomes regulation as an attempt to chart the digital future “in a human-centric and responsible way,” and emphasizes that AI must be conceived, designed, and implemented to “serve and protect people,” with ethical evaluation, internal control, and risk assessment alongside legislation. 3

COMECE further insists that AI should not generate biased or discriminatory decisions; it must safeguard human dignity, common good, subsidiarity, solidarity, and justice; and it calls for transparency, inclusion, accountability, impartiality, reliability, security, and privacy. 3

Pope Leo XIV frames AI governance criteria using Social Doctrine principles: when evaluating the concentration of power in the digital world, discernment relies on “the inalienable dignity of the human person, the common good, the universal destination of goods, subsidiarity, solidarity and social justice,” requiring that we assess whether digital infrastructures and algorithms truly foster participation and protect the vulnerable. 2

“Algor-ethics” and the responsibilities of developers, users, and politics

Catholic teaching emphasizes that AI ethics requires ethical inspiration and attention to duties, not only outcomes. Pope Francis explains that an ethical decision takes into account “not only an action’s outcomes but also the values at stake and the duties that derive from those values.” 11 He presents the Rome Call for AI Ethics (and the related “algor-ethics” approach) as a platform to translate shared principles across cultures and institutions into guidance for ethical moderation of algorithms. 11

Pope Leo XIV then narrows the focus toward specific moral obligations: developers have a particular ethical responsibility because “every design choice reflects a vision of humanity.” Developers are called to embed values with seriousness—especially “with transparency, responsibility toward affected communities and careful attention to ensuring that what is being cultivated is a genuine good.” 12

Meanwhile, the ethical call must also address the social and political layer of AI. Pope Francis states that the ethical center should be the human person, and Pope Leo XIV warns that political systems must not abdicate responsibility when governing AI’s effects. 11 10

The Latin American and Caribbean Episcopal Council emphasizes that the ethical assessment of AI depends on whether specific applications promote dignity and the common good, encouraging a “horizon of intelligence relacional” and a “spiritual” way of reading technology—aiming at integral human development, solidarity, fraternity, and truth. 13

Key ethical requirements implied by these teachings

Synthesizing the provided Catholic sources, the following requirements emerge as consistently implied:

• Primacy of the human person and conscience: AI should remain directed by human intelligence with conscience and freedom; technical systems do not replace moral agency. 9 8
• No discriminatory “less-worthy” treatment: systems that exclude people or make them “less worthy,” especially without meaningful appeal, violate dignity. 1
• Ethical discernment of design, not just use: evaluate what is embedded in data and models—because tools embody value-priorities. 1
• Accountability and oversight: robust legal frameworks and independent oversight are required; prudence may include a slower pace to protect people. 10 3
• Right-based human protection: respect fundamental rights, reduce unjust inequalities, and ensure the common good is promoted through institutions. 5 6 4
• Transparency and safeguards: privacy, security, inclusion, impartiality, and reliability are not optional “extras” but part of human-centric governance. 3 2

Conclusion

Catholic teaching on AI ethics and human dignity insists that AI belongs within a moral and social framework: it must be evaluated in light of the human person’s inalienable worth, the common good, justice, and the requirement that human conscience and freedom remain decisive. 2 1 4
