Pope Leo XIV: AI communication must preserve ‘human voices and faces’
Pope Leo XIV addressed pilgrims in St. Peter's Square on World Communications Day, urging that AI communication preserve human voices and faces. He called on Catholics and communicators to prioritize forms of communication that respect the truth of the human person, insisting technology should focus on human dignity. The pope noted the Vatican’s upcoming encyclical will tackle the ethical and social questions raised by artificial intelligence through Catholic social teaching. He also marked the start of Laudato Si’ Week, urging renewed care for creation and peace amid recent wars.

Pope Leo XIV used World Communications Day on May 17, 2026 to call for AI‑driven communication that safeguards human dignity, linking the appeal to the start of Laudato Si’ Week, a forthcoming encyclical on AI ethics, and a theological reflection on the Ascension 1 2.
The pontiff declared the year’s World Communications Day theme “Preserving Human Voices and Faces.”
He urged Catholics and all communicators to promote technologies that respect the truth of the human person, insisting that every innovation should be centered on that truth 1 2.
Leo XIV announced that the Vatican is preparing his first encyclical, which will address the ethical and social challenges of artificial intelligence through Catholic social teaching 1 2.
The address coincided with the launch of Laudato Si’ Week, a seven‑day focus on caring for creation inspired by Pope Francis’ 2015 encyclical.
Leo XIV linked ecological stewardship to peace, urging the Laudato Si’ Movement and all believers to renew their commitment to an “integral ecology” 1 2.
In his catechesis before the Regina Caeli, the pope highlighted the Ascension as a living bond that draws believers toward communion with the Father.
Quoting St. Augustine, he described the “head’s advance” as the hope of the members, emphasizing that Christ’s life is a continual “movement of ascent” toward light, forgiveness, and hope 1 2.
After the prayer, Leo XIV greeted a diverse crowd of pilgrims, including marching bands, university students, youth leaders, and confirmation candidates from various dioceses, underscoring the universal call to live the Gospel in everyday life 1 2.
Pope urges AI communication to preserve human dignity and authenticity
The headline captures a real and recurring concern in Catholic teaching: technology (including AI) must serve human dignity, truth, and authentic human relationships, and it must not replace the human person—especially in communication—by reducing persons to data, targets, or “content.”
Catholic social and moral teaching does not treat dignity as a slogan; it treats dignity as an objective foundation for rights and ethical evaluation. The Church insists that human dignity is intrinsic, rooted in the person’s nature, not in what technology can measure.
Pope Francis applies this directly to emerging technologies: technologies are ethically sound to the extent that they help respect dignity and increase its expression at every level of human life, and we must not treat a person’s worth as something “measured by data alone.”
This matters for “AI communication” because many AI systems (especially generative systems and recommender systems) can shape what people see, believe, and how they are treated. The Pope warns against delegating judgment to algorithms that process data that may be contaminated by societal prejudices and that may be collected surreptitiously—and against using past behavior to deny someone the chance to change.
“Authenticity” in the Christian sense is not merely “sounding real,” but being truthful and relational. Catholic teaching repeatedly connects communication to human encounter, not manipulation or dehumanization.
Pope Francis links the ethical evaluation of AI to the capacity to recognize the human “face,” not just interact with a machine as if it were a person. Pope Leo XIV similarly warns that the digital revolution can change how people perceive themselves and others, and that we can begin to interact with machines “as if they were interlocutors,” risking forgetting “how to recognize and cherish all that is truly human.”
So, the headline’s “preserve human dignity and authenticity” aligns with a deeper claim: AI can simulate aspects of reasoning and language, but it cannot replace moral discernment or genuine relationships.
Catholic teaching on communication is also sharply critical of communication becoming merely one-directional. Pope Leo XIV’s predecessor (as recorded in Acta Apostolicae Sedis) warns that when communication becomes exclusively one-way, audiences are deprived of the opportunity to participate, and then communicators “would no longer be communicators in the full, human sense.”
He also stresses that communicators must listen as well as speak, learn people’s needs, and present communications with “the sensitivity that human dignity requires.”
Applied to AI: “authentic” AI communication is not only about producing text or images, but about preserving dialogue, human responsiveness, and respect rather than using AI to dominate attention or bypass real encounter.
The Catholic lens on AI communication is not naïvely optimistic. It recognizes that digital systems can contribute to grave violations of dignity—especially through fake news, slander, and exploitation.
The Dignitas Infinita section on “Digital Violence” warns that digital technologies can create a world where “exploitation, exclusion, and violence grow,” including the ease of endangering someone’s good name with fake news and slander.
Pope Francis adds that the digital environment can include “loneliness, manipulation, exploitation, and violence,” citing risks like addiction, isolation, cyberbullying, and anonymous exposure of people’s lives—conditions that corrode authentic interpersonal respect.
This directly addresses “authenticity” because fake content and manipulative narratives do not merely misinform; they often harm persons, violating their dignity in public perception and social standing.
The Catholic response is not only moral condemnation; it is also formation—especially education and literacy—so that people remain free.
In Pope Leo XIV’s 2026 World Communications Day message, he calls it “increasingly urgent” to introduce media, information and AI literacy at all education levels so that individuals—especially young people—can gain critical thinking skills and grow “in freedom of spirit.”
He gives concrete safeguards that map closely onto the headline’s theme:
These points show that “preserving authenticity” is not only spiritual, but also practical: it involves protecting real persons’ identities and ensuring truthfulness and accountability in communication.
Catholic teaching consistently pairs dignity with the common good. Pope Leo XIV emphasizes that AI’s ethical use requires that “human dignity and the common good remain resolute priorities,” and that AI in healthcare must enhance—rather than replace—the personal relationship between patients and healthcare providers.
Likewise, communications technologies are meant to “connect the human family,” but this requires responsibility and discernment; AI must serve human interests as a whole and must not be judged solely by utility or efficiency.
Even in the realm of journalism and communication generally, Pope Francis warns about the spread of “fake news,” calling for rediscovery of the dignity of journalism and the responsibility to communicate the truth.
The headline’s message fits well with Catholic teaching: AI communication must be governed by human dignity, evaluated by whether it truly serves truth, freedom, dialogue, privacy, and authentic human relationships—and must resist both algorithmic manipulation and the temptation to treat machines as substitutes for persons.
