VATICAN CITY (CNS) -- Humanity must not allow technology, especially AI, to obscure, exploit or suppress human voices, needs, knowledge, talents, creativity and critical thinking abilities, Pope Leo XIV said.

Algorithms designed to maximize engagement on social media can lock people into "bubbles" of easy consensus and rage, weakening people's ability to listen and think critically, and increasing polarization, the pope wrote in his message for the World Day of Communications.

"Added to this is a naively uncritical reliance on artificial intelligence as an omniscient 'friend,' a dispenser of all information, an archive of all memory, an 'oracle' of all advice," which can also further erode the ability to understand what things really mean and to think analytically and creatively, he wrote.

The pope's message was released Jan. 24, the feast of St. Francis de Sales, patron saint of journalists. The Vatican and most dioceses will celebrate the World Day of Communications May 17, the Sunday before Pentecost. 

The theme for the church's 60th celebration of World Day of Communications is "Preserving human voices and faces," which the Dicastery for Communication announced Sept. 29.

The theme underlines the pope's focus on the need to respect the human person and each person's God-given uniqueness and diversity.

The challenge, he wrote, "is not technological, but anthropological. Protecting faces and voices ultimately means protecting ourselves."

Humanity can embrace the opportunities offered by digital technology and artificial intelligence "with courage, determination and discernment," he wrote, without hiding or ignoring the critical issues, problems and risks they pose.

The main concern is not what "machines" or technology can or will be able to do, Pope Leo wrote, "but what we can and will be able to do, growing in humanity and knowledge, with the wise use of such powerful tools at our service."

The heart of the problem, he wrote, is the human temptation to passively accept the fruits of knowledge without being an integral part of the technological process, without doing the needed research and without being held accountable and responsible regarding their use. 

"Giving up the creative process and surrendering our mental capacities and imagination to machines means burying the talents we have received to grow as people in relation to God and others," he wrote. "It means hiding our face and silencing our voice."

Without proper safeguards, he wrote, "digital technology risks radically altering some of the fundamental pillars of human civilization" since current technology is able to simulate "human voices and faces, wisdom and knowledge, awareness and responsibility, empathy and friendship."

"There has long been ample evidence that algorithms designed to maximize engagement on social media -- which is profitable for platforms -- reward knee-jerk emotions and penalize more time-consuming human expressions such as the effort to understand and reflect," the pope wrote.

"By closing groups of people into bubbles of easy consensus and easy indignation, these algorithms weaken the ability to listen and think critically and increase social polarization," he wrote, adding his warning about any naive and uncritical reliance on AI for information, remembering the past, "friendship" and advice.

"Although AI can provide support and assistance in managing communication tasks, shirking the effort to think for ourselves and settling for an artificial statistical compilation risks eroding our cognitive, emotional and communication skills in the long run," he wrote.

Pope Leo flagged the danger of letting AI systems take control of producing text, music and video, and allowing "masterpieces of human genius in the fields of music, art and literature" to become "mere training grounds for machines."

"Much of the human creative industry is thus at risk of being dismantled and replaced with the label 'Powered by AI,' transforming people into mere passive consumers of unthought thoughts, anonymous products, without authorship, without love," he wrote.

Pope Leo also highlighted the increased presence of "bots" and "virtual influencers" on people's social media feeds, and their ability to influence public debate and people's choices. 

Another danger, he added, was "anthropomorphizing" Large Language Models, which can imitate human emotions and appear "affectionate," potentially deceiving or influencing vulnerable people and exploiting the human need for relationships.

If people replace real human relationships with AI-trained systems, where "everything is made in our image and likeness," he wrote, people can build a "world of mirrors" and be robbed of the opportunity "to encounter others, who are always different from us, and with whom we can and must learn to engage."

AI and its propensity to "hallucinate" as well as its ability to fabricate "reality" make it increasingly difficult to distinguish fact and fiction, thus posing a great risk to journalism, he wrote.

"A failure to verify sources, together with the crisis in on-the-ground journalism, which involves the continuous gathering and verification of information wherever events occur, can create even more fertile ground for disinformation, causing a growing sense of mistrust, confusion and insecurity," the pope wrote.

And finally, he warned about the danger of having a "handful of companies" be in control of so much data and be able to "subtly influence behavior and even rewrite human history -- including the history of the Church -- often without us even realizing it."

What needs to be done, he wrote, is "not stop digital innovation, but to guide it, to be aware of its ambivalent nature" and to "raise our voices in defense of human beings, so that these tools can truly be integrated as our allies."

This alliance must be based on responsibility, cooperation and education, he wrote,

"Media and communication companies cannot allow algorithms designed to win the battle for a few extra seconds of attention at any cost to prevail over their professional values, which are aimed at seeking the truth," he wrote. "Public trust is earned through accuracy and transparency, not by chasing after any kind of engagement." 

"Content generated or manipulated by AI must be clearly labeled and distinguished from content created by humans," the pope wrote. Authorship, ownership and copyright must be protected.

"Information is a public good. A constructive and meaningful public service is not based on opacity, but on transparency of sources, inclusion of stakeholders and high standards of quality," he said in his message.

The pope called for increased media, information and AI literacy on all levels. "As Catholics, we can and must make our contribution so that people -- especially young people -- acquire critical thinking skills and grow in freedom of spirit."

More should be done, too, he added, in protecting people's face, image and voice from being used in "the creation of harmful content and behaviors such as digital fraud, cyberbullying and deepfakes that violate people's privacy and intimacy without their consent."

"We need faces and voices to represent people again," he wrote. "We need to cherish the gift of communication as the deepest truth of humanity, to which all technological innovation should be oriented."

Former prisoners of the German Nazi concentration and extermination camp Auschwitz-Birkenau view what is happening in the world today with concern. They ask themselves whether the most difficult lesson of their lives will continue to offer humanity any wisdom at all, says the Director of the Auschwitz-Birkenau State Museum, in an interview with Vatican News on Holocaust Remembrance Day.

WASHINGTON - On Ash Wednesday, February 18, Catholics in dioceses across the United States are invited to give to the annual Collection for the Church in Central and Eastern Europe, sponsored by the U.S. Conference of Catholic Bishops (USCCB).

This collection, which is in its 35th year, continues its mission of helping churches in nearly 30 countries recover from militantly atheist communist rule, including ministry and relief efforts related to the war against Ukraine.

Bishop Gerald L. Vincke of the Diocese of Salina, chairman of the USCCB’s Subcommittee on Aid to the Church in Central and Eastern Europe, witnessed the collection’s work in Ukraine last March. “I visited a shelter for families whose homes were destroyed and an orphanage for children whose parents were killed. Veterans I met with expressed their gratitude for therapy they have been able to receive for their post-traumatic stress,” he said.

“An elderly man who had survived a Siberian gulag told me, ‘What gives me hope is that, in the end, evil does not win.’ He is right – but that requires all of us to follow Christ’s call to build the kingdom of God. Pope John Paul II knew that in 1990 when he urged Catholics in the United States to join the great rebuilding effort in lands newly liberated from communist oppression – lands from which many of our families had immigrated,” continued Bishop Vincke.

The Collection for the Church in Central and Eastern Europe was the U.S. bishops’ response to that call. Many dioceses take up this annual collection on Ash Wednesday, though some dioceses have different dates. The online giving site iGiveCatholic also accepts funds for the program.

In 2024, gifts to the collection funded 547 grants totaling more than $9.5 million. Examples of how donations are used include:

• In Kokshetau, Kazakhstan, sisters of the Community of the Beatitudes expanded their mission of evangelization by establishing a day center for preschool children with Down syndrome and their families.
• In the Slovak Republic, a multi-faceted outreach to vulnerable pregnant women provides material assistance, counseling, training in prevention of abuse, and “Evenings of Mercy” a gathering featuring Mass, confessions, and healing prayers.
• One of the many projects in Ukraine trains lay leaders in the Ukrainian Greek Catholic Exarchate of Lutsk to develop new skills in pastoral and social ministry so they can help bring hope and comfort to people who have lost everything.
• A thousand-year-old Benedictine monastery in Hungary is helping clergy and laity discover the teachings of Vatican II on topics ranging from liturgy to interfaith relations.
• In Bulgaria, a village church has been able to engage in digital media evangelization and now offers a post-abortion healing ministry. They were also able to send young pilgrims to the Jubilee in Rome and financed English-immersion studies for a priest in order to reach non-Bulgarians.

“For 35 years, your contributions to the Collection for the Church in Central and Eastern Europe have made a profound difference. You have rebuilt cathedrals, renewed hope, healed the suffering and brought joy where there had been despair,” Bishop Vincke said. “As these churches continue to heal from old wounds and suffer new ones, it is my hope that you give generously and become part of our ongoing and loving response.”
