Pope Leo unveiled the Vatican’s new encyclical, "Magnifica Humanitas," warning that artificial intelligence risks becoming a tool of "domination, exclusion and death" unless governments and institutions place moral limits on the rapidly developing technology.

The Vatican is formally entering the global debate over artificial intelligence as governments and tech companies race to develop increasingly powerful AI systems with limited international regulation.

The pontiff invoked Pope Leo XIII’s 1891 encyclical "Rerum Novarum," which addressed worker exploitation during the Industrial Revolution, arguing that AI represents a similarly transformative moment threatening human dignity.

"Today we find ourselves facing a transformation of similar magnitude, with perhaps even greater consequences," the Pope said.

The pope warned about increasingly autonomous weapons systems that are beyond meaningful human control. He also said AI systems could block access to healthcare, employment and security because of biased data. He compared AI governance to nuclear arms control.

"Like nuclear energy, it must be at the service of all and of the common good," he said.

The pope said disarming AI alone is not enough and called on governments and institutions to "build" systems rooted in trust and human dignity. Recalling devastating floods in Peru, he said rebuilding means restoring trust and hope.

The pope also laid out the church’s broader argument about humanity and technology.

"The person bears within him- or herself a freedom, an interiority and a vocation to love and worship that no machine can replace," he said.

The Vatican is attempting to insert moral theology into a largely secular technological arms race.

"Stay awake," the pope urged, warning humanity not to surrender moral judgment to machines.

Pope Leo XIV last Friday urged African youth to work toward improving their own countries rather than migrating elsewhere in search of better opportunities.

The leader of the Roman Catholic Church directed his remarks to university students at the Catholic University of Central Africa in Yaoundé, the capital of Cameroon, during an 11-day apostolic journey in Africa. 

"In the face of the understandable tendency to migrate — which may lead one to believe that elsewhere a better future may be more easily found — I invite you, first and foremost, to respond with an ardent desire to serve your country and to apply the knowledge you are acquiring here to the benefit of your fellow citizens," Leo said. 

While displacement in Africa has steadily increased in recent years amid economic and political challenges, Leo said each country’s rising generations should be "committed to society," reflect their nations’ needs and confront systemic issues at home.

"Africa, indeed, must be freed from the scourge of corruption. For young people, this awareness must take root from their years of formation," he said.

"These are the witnesses of wisdom and justice, of which the African continent needs."

He added that through education and spiritual formation, "you learn to become builders of the future of your respective countries and of a world that is more just and humane."

POPE LEO SAYS HE'S UNAFRAID OF THE TRUMP ADMIN AFTER PRESIDENT CALLS HIM 'TERRIBLE' ON FOREIGN POLICY

According to the World Migration Report, most of Africa’s displacement occurs internally within the continent, with 21 million Africans recorded as living in another African country in 2020.

Overseas African migration has also steadily increased, with figures more than doubling between 1990 and 2020.

In 2020, roughly 11 million Africans reportedly migrated to Europe, 5 million to Asia and 3 million to Northern America.

MORNING GLORY: LEO'S LAUNCH

The causes of displacement are largely attributed to political conflict, corruption, violence and economic hardship, including widespread poverty. 

These factors are particularly pronounced in countries such as Somalia, one of Africa’s largest sources of refugees; Nigeria, which is riddled with natural disasters and economic pressures; and Sudan's surrounding areas, where civil war, political instability and food insecurity have driven large-scale displacement.

The Pope’s remarks come just days after President Donald Trump criticized Leo on Truth Social, calling him "weak on crime, and terrible for foreign policy." 

The backlash followed the pontiff’s criticism of the U.S.-Israeli war in Iran and his appeal for a return to peace.

Tensions between the two boiled over several days before the Pope said last Saturday that it was "not in my interest at all" to debate the president.

Leo has insisted that his position is focused on bridging divides among nations and promoting peace and reconciliation.

Pope Leo XIV said Saturday that remarks he made this week in which he said the "world is being ravaged by a handful of tyrants" were not directed at President Donald Trump, a report said. 

The pope, speaking onboard a flight to Angola during his 10-day tour of Africa, said reporting about his comments "has not been ‌accurate in all its aspects" and his speech "was ⁠prepared two weeks ago, well before the president ever commented on myself and on the message of peace that I am promoting," according to Reuters.

The news outlet cited the pope as saying his comments were not aimed at Trump.

"As it happens, it was looked at as if I was trying to debate the president, which is not in ​my interest at all," the pope reportedly said.

Vice President JD Vance later took to X to thank the pope for clearing the record.

"While the media narrative constantly gins up conflict — and yes, real disagreements have happened and will happen — the reality is often much more complicated," Vance wrote. "Pope Leo preaches the gospel, as he should, and that will inevitably mean he offers his opinions on the moral issues of the day.

"The President — and the entire administration — work to apply those moral principles in a messy world," he continued. "He will be in our prayers, and I hope that we'll be in his."

The vice president's comments came days after he told Fox News' Bret Baier on "Special Report" that it would be best for the Vatican to "stick to matters of morality."

"Let the President of the United States stick to dictating American public policy," Vance said Tuesday.

Trump last Sunday accused Pope Leo XIV of being "terrible" on foreign policy after the pontiff criticized the U.S.-Israeli war on Iran.

"He talks about 'fear' of the Trump Administration, but doesn’t mention the FEAR that the Catholic Church, and all other Christian Organizations, had during COVID when they were arresting priests, ministers, and everybody else, for holding Church Services, even when going outside, and being ten and even twenty feet apart," Trump wrote in a Truth Social post. 

"I don’t want a Pope who thinks it’s OK for Iran to have a Nuclear Weapon."

POPE LEO SLAMS THOSE WHO 'MANIPULATE RELIGION' FOR MILITARY OR POLITICAL GAIN, TRUMP RESPONDS

During a speech in Cameroon on Thursday, the pope said, "We must make a decisive change of course — a true conversion — that will lead us in the opposite direction, onto a sustainable path rich in human fraternity.

"The world is being ravaged by a handful of tyrants, yet it is held together by a multitude of supportive brothers and sisters.

"Woe to those who manipulate religion and the very name of God for their own military, economic or political gain, dragging that which is sacred into darkness and filth."

The Chinese government is increasing pressure on underground Catholic communities to join the state-controlled church while tightening surveillance and restrictions on an estimated 12 million Catholics, according to a Human Rights Watch report.

The group said in its report that the increased pressure is part of a decade-old campaign to ensure religious groups align with Communist Party ideology.

The Associated Press reported that the Chinese government has rejected the claim, saying Human Rights Watch is "consistently biased against China."

China’s Catholics have long been split between a state-run church and an underground church loyal to the Vatican. In 2018, Pope Francis reached a deal allowing the Chinese government a role in appointing bishops to ease tensions.

"A decade into Xi Jinping’s Sinicization campaign and nearly eight years since the 2018 Holy See-China agreement, Catholics in China face escalating repression that violates their religious freedoms," Human Rights Watch researcher Yalkun Uluyol said in the report. 

"Pope Leo XIV should urgently review the agreement and press Beijing to end the persecution and intimidation of underground churches, clergy, and worshipers."

The Chinese Foreign Ministry spokesperson’s office told The Associated Press that Human Rights Watch "fabricates all manner of lies and rumors and lacks any credibility whatsoever."

The office added that the government "oversees religious affairs in accordance with the law and protects citizens’ freedom of religious belief and normal religious activities."

Human Rights Watch said its researchers are not allowed into China and that the report is based on interviews with people outside the country who had firsthand knowledge of Catholic life in China, along with experts on Catholicism and religious freedom.

The 2018 agreement stipulates that Beijing proposes candidates for bishop, which the pope can veto, though the full text has never been made public.

In June 2025, Pope Leo XIV, who had just become the pope, appointed a Chinese bishop under the 2018 agreement and said he would continue to honor the deal "in the short term."

"I’m also in ongoing dialogue with a number of people, Chinese, on both sides of some of the issues that are there," Leo said. "It’s a very difficult situation. In the long term, I don’t pretend to say this is what I will and will not do, but after two months, I’ve already begun having discussions at several levels on that topic."

Since 2018, Human Rights Watch says Chinese authorities have pressured underground Catholics to join the state-run church through detentions, disappearances and house arrests, citing accounts from unnamed individuals who have left China.

The report also said China has tightened ideological control, surveillance and restrictions on religious activity and foreign ties, including requiring state approval for clergy travel, while officially recognizing and closely overseeing five religions: Buddhism, Taoism, Catholicism, Protestantism and Islam.

Xi Jinping said in 2016 he would "Sinicize" the country’s religions, a policy aimed at aligning religious practices with Communist Party ideology.

Human Rights Watch said authorities have taken sweeping steps to curb religious practice, including tearing down churches and crosses, blocking gatherings at unregistered churches and seizing religious materials not approved by the state.

The group said the broader "Sinicization" campaign has also led to intensified crackdowns on Tibetan Buddhists and Muslims.
