Trump suggests pope unaware of Iran nuclear stance despite Leo’s repeated calls for disarmament #Catholic President Donald Trump warned against a nuclear‑armed Iran, reacting to Chicago Mayor Brandon Johnsonʼs May 28 meeting with Pope Leo XIV at the Vatican, where the mayor said they discussed U.S. immigration and the Iran conflict.Trump posted, “Someone should explain to the Pope that the Mayor of Chicago is useless, and that Iran cannot have a Nuclear Weapon.” He also shared screenshots of the mayor’s posts with pictures of him and the Chicago-born pope sharing gifts and praying. Trump made the comments in a May 30 post on Truth Social.The president has repeatedly claimed, without evidence, that Leo wants the Middle Eastern country to develop nuclear armaments.Leo has rejected those allegations. On May 5 at Castel Gandolfo he stated that the Church "has spoken for years against all nuclear weapons." Later, Vatican Secretary of State Cardinal Pietro Parolin stated that the Holy See "has always worked, and will continue to work, on nuclear disarmament."The White House and Chicago mayor’s office did not immediately reply to requests for comment.Trump sharply criticized Pope Leo XIV in April, calling him “weak on crime” and “terrible for foreign policy” and saying he is “not a fan” of the pope.Trump expressed his disapproval of Leoʼs public statements denouncing the U.S.-led war on Iran. The Holy Father has repeatedly called for peace amid the ongoing conflict.The pope has said he is “not afraid of the Trump administration or of speaking out loudly about the message of the Gospel.”

Pope Leo unveils his encyclical: AI has ‘even greater consequences’ than Industrial Revolution #Catholic VATICAN CITY — Pope Leo XIV on Monday personally attended the presentation of his first encyclical, Magnifica Humanitas, in an uncustomary gesture. Upon his arrival at the event, held in the Vaticanʼs Synod Hall, he was greeted with sustained applause from an audience made up of members of the Roman Curia, representatives of academia, and the diplomatic corps.Among the speakers was Canadian Christopher Olah, co-founder of Anthropic, one of the leading artificial intelligence (AI) companies. The firm has recently had tensions with the administration of U.S. President Donald Trump after prohibiting the U.S. Department of Defense from using its software for military purposes.Some observers had raised concerns about including a representative of a major tech company like Anthropic in an event of this kind. The Holy Father himself dispelled any hesitation by thanking Olah for his presence: “What a great sign of hope it is that with our differences we can listen to one another,” he said in his remarks.“This interchange clearly bespeaks the gravity of the moment, as well as confidence that together we can discern the major questions of our time, and so the future of humanity,” he added.In his remarks prior to the pope’s address, Olah echoed the same idea: "That is why, if we want this technology to go well, it is enormously important that there be people outside those incentives — people who care about things going well and insist on safety, who are paying close attention, who are willing to say hard things, who are willing to be our earnest, thoughtful, critics. It is through dialogue and mutual effort, through the push and pull, that humanity will achieve great things. That is what I see in Magnifica Humanitas, and it is why I am grateful to His Holiness and the Church for taking up this work of discernment.” Christopher Olah, co-founder of AI company Anthropic, says he is grateful to Pope Leo XIV and the Church for “taking up this work of discernment” on artificial intelligence, during his address at the presentation of the encyclical Magnifica Humanitas on May 25, 2026, in the Synod Hall of the Vatican. | Credit: Daniel Ibáñez/EWTN News/Vatican Pool Olah, who is not a believer, also issued a call to various sectors — religious communities, civil society, academics, and governments — to follow the pope’s example with this document: “to take this seriously, to look closely, and to push events in a better direction. We need informed critics who will tell the labs when we are failing. We need moral voices that the incentives cannot bend.”It is no coincidence that Leo XIV signed his first encyclical on May 15, the same date on which his predecessor Leo XIII promulgated Rerum Novarum (“On New Things”) in 1891 in response to the dehumanization brought about by the Industrial Revolution. As the pope explained, the world today faces a transformation of perhaps even greater scope.“Today we find ourselves facing a transformation of similar magnitude, with perhaps even greater consequences. Artificial intelligence already touches many areas of our lives and affects decisions that shape human coexistence,” he said.The pope expressed particular concern about the impact of new technologies on the conduct of war, which, he warned, is changing dramatically.“Like the earlier Leo, I feel entrusted to look upon another huge transformation with eyes of faith, with lucidity of reason, with openness to mystery, and with cries of the poor and the earth resounding in my heart,” he said.The Holy Father also described the method behind the drafting of this magisterial document, which began in July 2025 at the papal residence in Castel Gandolfo. In it, he seeks to reaffirm what makes us human in a society shaped by technology.He emphasized that Magnifica Humanitas was born from listening: “I have listened to scientists and engineers who work with sincere enthusiasm on technologies capable of alleviating immense suffering, to political leaders and public officials who have perseveringly sought just rules, to parents and teachers who are deeply concerned for the future of younger generations,” he said, without naming individuals.At the same time, he acknowledged hearing “Other very troubling voices have also reached me about increasingly autonomous weapons systems practically beyond any human reach to govern them effectively.”“I hear very troubling accounts of algorithms that can block access to healthcare, employment, and security on the basis of data tainted by prejudice and injustice. And Iʼve heard the silence of those who have no voice when decisions are made — decisions likely to generate new forms of exclusion and suffering,” he lamented.In line with the document — which states that artificial intelligence is not morally neutral — the pope called for AI to be “disarmed.”“The word is strong, I know, but deliberately chosen because this moment needs words capable of attracting attention, awakening consciences, and indicating paths forward for humanity,” he warned.“The Church has long been working for nuclear disarmament, aware that every great technical power can affect peopleʼs lives, and so must be accompanied by adequate moral discernment and public control. Nuclear disarmament remains a service to peace and the dignity of the human family,” he added.Also speaking at the presentation were three cardinals of the Roman Curia: Secretary of State Pietro Parolin; Cardinal Víctor Manuel Fernández, prefect of the Dicastery for the Doctrine of the Faith; and Cardinal Michael Czerny, SJ, prefect of the Dicastery for Promoting Integral Human Development.Two theologians also took the floor: Anna Rowlands, a specialist in Catholic social teaching and migration ethics at Durham University, and Leocadie Lushombo, an expert in political theology and Catholic social thought at the Jesuit School of Theology of Santa Clara University in California.This story was originally published by ACI Prensa, EWTN News' Spanish-language news service.
