On May 8, 2025, history was made in the Sistine Chapel. Cardinal Robert Francis Prevost — a Chicago-born Augustinian priest and missionary — emerged onto the balcony of St. Peter’s Basilica as Pope Leo XIV, the first American to lead the Roman Catholic Church in its 2,000-year history. He has now passed the one-year mark, and on May 25, 2026, he released the document that may come to define his papacy: Magnifica Humanitas, a 42,300-word encyclical on artificial intelligence and the human person.

Who Is Pope Leo XIV?
Born Robert Francis Prevost on September 14, 1955, in Chicago, Illinois, Leo XIV spent decades as a missionary in Peru before rising through the ranks of the Augustinian order. Pope Francis made him a cardinal in 2023 and head of the powerful Dicastery for Bishops — the Vatican office responsible for selecting bishops around the world.
When Francis died on April 21, 2025, few outside Vatican circles had Leo on their shortlist. His election on the fourth ballot of the 2025 conclave — concluded in just two days — stunned many observers. “The prospect of an American pope had seemed impossible,” one cardinal told journalists, citing the United States’ military and economic dominance as a long-standing barrier.
📜 Magnifica Humanitas: The Encyclical That Defines His Papacy
On May 25, 2026, Pope Leo XIV released Magnifica Humanitas (“Magnificent Humanity”), the first encyclical of his papacy. At 42,300 words, it is one of the longer encyclicals in modern Church history — and arguably the most consequential papal teaching on technology since Pope Pius XII’s 1957 Miranda Prorsus on radio, film, and television.
The Pope signed the document on May 15, 2026 — the 135th anniversary of Pope Leo XIII’s Rerum Novarum, the landmark 1891 encyclical on workers’ rights that founded modern Catholic social teaching. The choice of date was deliberate: Leo XIV is positioning Magnifica Humanitas as a direct successor to Rerum Novarum, arguing that just as the Industrial Revolution demanded a new social doctrine, so does the AI revolution.
What Magnifica Humanitas Argues
The encyclical addresses familiar AI concerns — job insecurity and inequality, manipulation of information, privacy violations, ideological bias, and autonomous weapons systems — but identifies a deeper danger: that human beings may begin to see themselves and others as products of computation rather than persons. Leo calls for AI to “be disarmed” and directed “toward the common good,” framing technological policy as a religious and moral imperative, not merely a regulatory one.
In a striking symbolic move, the Pope presented the encyclical personally at the Vatican’s Synod Hall — unlike most popes who delegate to cardinals — alongside Anthropic co-founder Dario Amodei. The pairing signaled Leo’s intent to engage directly with frontier AI developers rather than condemn from a distance. Time, the Washington Post, and the National Catholic Reporter all framed the encyclical as the most significant intervention by any religious leader on the AI question to date.
An ironic footnote: shortly after publication, AI-detection tool Pangram flagged sections of the encyclical as likely AI-generated. Snopes investigated and rated the claim unproven, noting that Pangram has well-documented false-positive issues and that the original Substack post which sparked the story explicitly suggested any AI use would have been by Vatican staffers, not the Pope himself.
The Biggest Moments of Pope Leo XIV’s First Year
1. A Quiet Start — Then a Loud Awakening
Vatican insiders described Leo’s first months as deliberately measured. He listened more than he spoke, continued initiatives left by Pope Francis — including the closing of the 2025 Jubilee Year — and focused on internal governance. In January 2026, he convened an extraordinary consistory of cardinals, the first since 2014, fulfilling a promise to include them as genuine advisors rather than ceremonial figures.
Observers noted a stylistic shift from his predecessor: less street theatre, more institutional deliberation. But 2026 has made clear that Leo XIV is far from silent.
2. The Iran War and His Unflinching Call for Peace
The defining geopolitical crisis of Leo’s first year has been the 2026 Iran War, initiated by the United States and Israel. From early in the conflict, the Pope spoke repeatedly and clearly: bombing must stop, weapons must fall silent, and diplomacy must prevail.
At an Easter Sunday Urbi et Orbi blessing, Leo urged world leaders to “lay down their weapons and choose peace.” He warned of a “delusion of omnipotence” driving military action and declared: “God does not bless any conflict.” His message was unmistakably directed at the powerful — and the powerful noticed.
3. The Trump vs. Pope Feud That Shocked the World
In April 2026, as Leo was on an 11-day Africa tour, U.S. President Donald Trump posted a blistering social media attack, calling the Pope “WEAK on Crime, and terrible for Foreign Policy.” He also suggested Leo should be “thankful” for his election, implying the Pope owed his position to Trump’s influence. Trump additionally posted — then deleted — an AI-generated image of himself depicted as Jesus Christ, sparking widespread outrage in religious communities.
Leo’s response from the papal plane was swift and unambiguous: “I have no fear of the Trump administration or of speaking out loudly about the message of the Gospel. That is what I am here to do.”
The confrontation was unlike anything in modern papal history. Pope John Paul II opposed the U.S. invasion of Iraq in 2003 — but did so through diplomatic channels. Leo XIV, the first American pope, spoke to an American president in plain, direct language, and did not flinch.
4. The Africa Journey: A Papacy That Found Its Voice
Leo’s April 2026 trip through Algeria, Cameroon, Angola, and Equatorial Guinea — eleven days, four countries, eighteen flights — is widely regarded as the moment his papacy came fully into focus. In Bamenda, Cameroon — a city ravaged by an ongoing separatist war — he stood before 100,000 faithful and declared: “The world is being ravaged by a handful of tyrants, yet it is held together by a multitude of supportive brothers and sisters.”
An Anglophone separatist alliance declared a three-day ceasefire in honour of his visit — the first in years in a conflict that has killed over 6,500 people. In Equatorial Guinea, he stood feet away from an authoritarian president and his convicted son, and preached without softening a syllable of Catholic social teaching.
5. A Return to Catholic Tradition
Liturgically, Leo XIV has signaled a shift. On Holy Thursday, he washed the feet of 12 Roman priests — reverting to the traditional form rather than Pope Francis’s practice of washing the feet of immigrants and prisoners. On Good Friday, he personally carried the cross at the Colosseum’s Stations of the Cross, something no recent pope has done. At his first Mass in the Sistine Chapel, he chose a ceremonial staff made for Pope Benedict XVI, prompting some to speak of a symbolic “return to order.”
What Makes Leo XIV Different from Pope Francis?
The Italian saying goes: “After a fat pope, a thin pope” — meaning each papacy tends to correct the excesses of the one before it. Leo XIV has adopted a different governing style from Francis in several clear ways:
- Consultation over solo decisions: Leo gathers cardinals regularly, something Francis did less frequently.
- Quieter gestures, louder words: Francis was famous for dramatic symbolic acts. Leo makes fewer symbolic moves but speaks more directly on geopolitics.
- Institutional focus: Leo has prioritised Vatican governance reform and the role of the College of Cardinals as genuine advisors.
- Continuity on core issues: On migration, environmental protection, and care for the poor, Leo has continued Francis’s direction.
One Vatican insider summarised it this way: “Francis made you feel. Leo makes you think.”
What’s Coming Next
With Magnifica Humanitas released, attention now turns to implementation. Leo’s team is expected to follow the encyclical with a Vatican-hosted summit on AI ethics later in 2026, drawing in religious leaders of other faiths alongside major AI developers. The Pope is also scheduled to visit Turkey on November 27–30, 2026 — his first international trip outside Italy since the Africa tour — for an ecumenical commemoration of the 1,700th anniversary of the First Council of Nicaea, alongside Ecumenical Patriarch Bartholomew I.
Why the World Is Watching
Pope Leo XIV leads a Church of 1.5 billion Catholics at a moment of extraordinary global turbulence: an active war in the Middle East, rising authoritarianism, the disruption of AI, and a United States in the midst of its 250th anniversary and a political culture war.
He is the first pope in history to have grown up in the same country as a U.S. president, and that dynamic has produced one of the most unusual relationships in modern geopolitics. He is simultaneously an American and a global figure whose loyalty is, by definition, to no nation. Whether you are Catholic or not, what Leo XIV says and does matters. He is one of the most prominent moral voices on the planet — and in his first year, he has shown he intends to use that voice.
