Apostolic nuncio calls for ‘moral voice’ in AI development
Archbishop Gabriele Giordano Caccia, apostolic nuncio to the U.S., urged a moral voice in AI at a Georgetown University panel. The panel reviewed Pope Leo XIV’s encyclical Magnifica Humanitas, which calls for technology that serves the common good but stops short of prescribing policy. Caccia warned that AI should not replace human conscience in life‑and‑death decisions and highlighted risks of algorithmic bias in healthcare, employment and security. He urged Catholics, including engineers and business leaders, to participate in shaping AI’s moral direction.

The apostolic nuncio to the United States, Archbishop Gabriele Giordano Caccia, called for a stronger moral voice in artificial-intelligence development during a Georgetown University panel focused on Pope Leo XIV’s encyclical Magnifica Humanitas. Speakers said the document offers broad ethical guidance centered on the common good, while leaving specific policy responses to further discussion. 1
The Sept. 9 panel, titled “AI, Catholic Social Teaching, and Pope Leo’s Invitation to Dialogue with the World,” examined the encyclical’s appeal for a shared human effort to ensure that technology serves humanity rather than harms it. Panelists noted that the document does not prescribe detailed policies for addressing AI’s ethical and social risks. 1
Caccia said the debate needs a moral voice because technological possibility does not determine what should be done. He framed decisions about using AI as moral choices, emphasizing that not every available technological capability should automatically be adopted. 1
Caccia warned against delegating decisions affecting human lives to AI systems. He distinguished algorithms from human conscience and stressed the importance of preserving human relationships and accountability. 1
In Magnifica Humanitas, Pope Leo rejects the concept of “artificial moral agents” and the idea that machines can distinguish right from wrong more consistently than people. The encyclical states that moral judgment involves conscience, personal responsibility, and recognizing others as persons, and therefore says lethal or otherwise irreversible decisions must not be entrusted to artificial systems. 1
Caccia also raised concerns about AI-assisted decisions involving healthcare, employment, and security. He said biased or unjust data could cause algorithms to deny access to services and create new forms of exclusion and suffering. 1
Caccia endorsed the encyclical’s statement that AI “needs to be disarmed.” He said the deliberately strong language was intended to draw attention, awaken consciences, and point toward possible paths for humanity while discussions continue. 1
He described the Church’s responsibility as extending beyond bishops and other pastoral leaders. Catholics working in business, engineering, economics, and technology, he said, also have a role in addressing the moral questions raised by AI. 1
Jasmine Sun, a journalist covering AI and Silicon Valley, said she was surprised by the level of attention the encyclical received from people in the AI industry. She attributed that engagement partly to a perception that Silicon Valley’s profit motive is insufficient by itself to guide the industry. 1
Molly Kinder, CEO of the Breakwater Initiative, said the Church’s appeal lies in its emphasis on wisdom, moral leadership, and humanity. She contrasted traditional ideas about human purpose and work with some Silicon Valley visions of an AI-driven future centered on leisure or reduced employment. 1
Caccia said he was positively surprised by the encyclical’s reception. He emphasized that it does not claim to provide definitive answers, but instead raises shared questions for society to address collectively. 1*
AI must be guided by Catholic moral principles
Yes. From a Catholic perspective, AI must be guided by moral principles because technology is ordered to the human person, not the reverse.
Key principles include:
In short, AI should be human-centered, morally accountable, transparent, and directed toward truth, justice, solidarity, and the flourishing of every person.
