Pope Leo Xiv

Pope Leo XIV has published the first encyclical of his pontificate, warning that artificial intelligence risks creating a new “Tower of Babel” built on technocratic power, dehumanisation and moral confusion Pope Leo XIV has published the first encyclical of his pontificate, issuing a warning against the dangers posed by artificial intelligence and what he describes as a growing “culture of power” threatening the dignity of the human person. Magnifica Humanitas (“Magnificent Humanity”), released by the Vatican on 25 May after being held under strict embargo until late Monday morning in Rome, is the Holy Father’s most substantial intervention yet in the global debate surrounding AI and the technological transformation of society. The encyclical argues that humanity now stands between two paths: the construction of a new “Tower of Babel” founded on pride, uniformity and technocratic power, or the rebuilding of a new Jerusalem grounded in solidarity, communion and God-centred human fraternity. “Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together,” the Pope writes in the opening paragraphs of the encyclical. The 230-paragraph document is the first major social encyclical of Leo XIV’s pontificate and immediately places him within the long tradition of modern Catholic social teaching stretching back to Pope Leo XIII’s Rerum Novarum in 1891. Far from rejecting technological progress outright, Leo XIV repeatedly insists that technology is a fundamentally human achievement capable of serving the common good. However, he warns that technological systems can never be considered morally neutral and must remain subordinate to the dignity of the human person. “We cannot consider AI to be morally neutral,” the Pope states. The encyclical presents artificial intelligence as one of the defining res novae — “new things” — confronting the modern world, the language traditionally used by the Church to describe the upheavals of the industrial revolution. The document states that unprecedented technological power is increasingly concentrated in the hands of private actors operating beyond effective political oversight, creating new dangers for democracy, labour, truth and peace. “More power does not necessarily imply something better,” it states. Much of the encyclical is devoted to explaining why the Church believes artificial intelligence cannot be equated with human intelligence. The Pope insists that AI systems, however sophisticated, remain incapable of moral reasoning, authentic relationships or genuine human experience. “So-called artificial intelligences do not undergo experiences, do not possess a body, do not feel joy or pain,” the encyclical says. “Nor do they have a moral conscience.” Leo XIV repeatedly returns to the theme of human dignity, grounding the entire encyclical in the belief that every person possesses an “infinite dignity” rooted in creation in the image of God rather than in usefulness, efficiency or productivity. “The fundamental dignity of each person,” he writes, “is neither acquired nor earned, nor does it need to be justified.” The Pope warns that the unchecked growth of AI risks creating new forms of dehumanisation in which human beings are valued according to economic output, algorithmic usefulness or digital visibility. He cautions against reducing human judgement to automated systems and criticises cultural movements that treat technological transcendence as a substitute for spiritual fulfilment. One of the most striking sections of the document is its sustained critique of transhumanist and posthumanist ideologies, which seek to overcome biological limitations through technological enhancement. Without naming particular movements or figures, Leo XIV argues that such projects reflect humanity’s recurring temptation to seek salvation apart from God. “Babel thus reveals the limits of any effort that, however grandiose, arises from self-affirmation, sacrifices human dignity for efficiency and aspires to reach heaven without God’s blessing,” the encyclical says. The encyclical also addresses the growing political and social consequences of AI-generated misinformation and manipulated media. Leo XIV warns that artificial intelligence is rapidly transforming the public square and undermining trust in democratic institutions through the spread of falsehoods and synthetic content. “Disinformation finds a powerful amplifier in AI,” the document states. The Pope argues that truth itself must be defended as a “common good” and calls for what he describes as an “ecology of communication” rooted in responsibility, education and human relationships rather than manipulation and profit. “The search for truth is an essential element of democracy,” he writes. Questions surrounding labour and the future of work occupy another substantial portion of the encyclical. Leo XIV warns against economic systems that prioritise efficiency over workers and expresses concern about automation displacing millions of people while weakening social bonds and family life. The Pope also calls for stronger political oversight of AI systems, greater international cooperation and safeguards against the monopolisation of data and digital infrastructure. In one of the encyclical’s most arresting phrases, Leo XIV urges world leaders to “disarm AI”. “Disarming AI means freeing it from the mentality of ‘armed’ competition,” the Pope writes, warning against an escalating technological arms race between states and corporations. The document devotes an extended section to the dangers posed by autonomous weapons systems and the growing use of AI in warfare. Leo XIV argues that artificial intelligence is accelerating the pace and destructiveness of conflict while distancing human beings from moral responsibility for violence. “AI acts as an accelerating factor” in changing the nature of war, he writes. The Pope condemns what he calls the “normalisation of war” and criticises a global culture increasingly resigned to permanent conflict, weakened diplomacy and the collapse of multilateral institutions. “This culture of power infiltrates society,” he warns, “normalising war.” Despite the encyclical’s sombre tone, the document concludes on a strongly hopeful note centred on the Christian doctrine of the Incarnation. Against ideologies promising technological transcendence, Leo XIV points to Christ as the true fulfilment of humanity. “At the heart of everything is the mystery of the Incarnation, the Word who became flesh and dwelt among us,” he writes. The final pages call on Catholics to resist despair and instead help build what the Pope repeatedly describes as a “civilisation of love” capable of directing technological progress towards authentic human flourishing. “In the era of artificial intelligence,” the Pope writes, “when human dignity is threatened by new forms of dehumanisation, ours is the pressing duty to remain profoundly human.”

Magnifica Humanitatis will reportedly place human dignity at the centre of the Church’s response to artificial intelligence as Pope Leo XIV addresses war, algorithms and the moral limits of technological progress Pope Leo XIV will publish his first encyclical on Monday, warning against the dangers of transhumanism and the dehumanising effects of artificial intelligence, according to details revealed in advance by Vatican correspondent Nico Spuntoni. The document, titled Magnifica Humanitatis , has reportedly been described inside the Vatican as the defining text of the new pontificate and places the defence of human dignity at the centre of the Church’s response to rapid technological change. According to Spuntoni, the encyclical argues that humanity now stands “at a crossroads between self-sufficiency and solidarity” as artificial intelligence becomes increasingly embedded in political, economic and social life. The text frames that struggle through biblical imagery while returning repeatedly to the theological significance of the Incarnation. Nico Spuntoni wrote that Leo XIV presents “contemplation of the Incarnate Word” as the answer to what the Pope calls “the eclipse of the meaning of what it means to be human”. The encyclical is expected to expand substantially on comments made by the Pope shortly after his election when he explained why he had chosen the name Leo. Addressing the College of Cardinals, the Pope said Leo XIII had confronted “the social question in the context of the first great industrial revolution”, while the Church today must respond to “another industrial revolution and to the developments of artificial intelligence, which bring new challenges for the defence of human dignity, justice and work”. Far from rejecting technological development altogether, the encyclical reportedly argues that artificial intelligence must remain subject to moral responsibility and ordered towards the common good. The Pope is also said to warn against any attempt to replace or transcend the human person through technology. Furthermore, Nico Spuntoni reported that Leo XIV criticises those who seek “to transcend humanity through technology”, while insisting on what he previously described as a “healthy sense of proportion” in relation to scientific development. The document reportedly returns several times to the question of human dignity as the measure against which all technological progress must be judged. In one passage referenced by Spuntoni, the Pope stresses that the human person possesses inherent dignity because each person is “willed, created, and loved by God”. That theme had already appeared in the Pope’s message for this year’s World Communications Day, in which he quoted St Gregory of Nyssa’s teaching that mankind possesses “a royal character” because humanity is created in the image of God. According to Nico Spuntoni’s account, the Pope expresses particular concern about what he sees as the erosion of moral accountability through reliance on algorithms and automated systems. The encyclical reportedly develops warnings Leo XIV issued earlier this year in a message for the International Day of Mathematics, when he called for algorithms to respect “the integral growth of the person” and not exclude “the moral dimension of these emerging technologies”. The impact of artificial intelligence on relationships and public discourse also features prominently in the text. Spuntoni said the Pope warns against forms of digital communication that undermine truth and human freedom, echoing earlier appeals from the pontiff for technology to remain at the service of authentic human interaction. The encyclical is also expected to address the military use of artificial intelligence. Pope Leo, who has appealed for peace since his election, reportedly insists on the ethical limits that must govern technological development in the defence sector. Nico Spuntoni suggested the Pope also uses the document to defend multilateral cooperation at a time of increasing geopolitical instability and international fragmentation. The encyclical is also likely to reinforce Leo XIV’s growing reputation as a pontiff deeply shaped by the intellectual legacy of St Augustine and Pope Benedict XVI. Spuntoni noted that the document revisits themes explored by Benedict in Spe Salvi , particularly the danger of mankind placing excessive faith in its own power and technological capability. According to Spuntoni, the Pope rejects the idea that Catholic social teaching is merely sociological or political, instead presenting it as something rooted directly in Christ and the Gospel. Ultimately, the encyclical does not condemn artificial intelligence itself, but instead seeks to direct technological development towards the service of humanity and the common good. In doing so, according to Spuntoni, the Pope expresses hope that mankind can still place technological progress at the service of human dignity rather than allow it to diminish or replace it. The topic of the text is as expected. The Pope’s choice of name and subsequent comments on artificial intelligence made it almost certain that this would be the theme of his first encyclical. The antimilitarist stance is also not surprising. However, the succinct way in which the pontiff has drawn together two major themes of his pontificate is characteristic of both the diplomatic ability and quiet confidence he has exuded since taking office. JD Vance has already said that he is “looking forward to reading” Magnifica Humanitatis, and it is likely that the text will prove influential on the world stage. By linking war with the topic of AI, the Pope has adeptly given world leaders a way to discuss the need for restraint in conflict without stoking partisan tensions. The full text will be presented tomorrow at 11.30am in the Vatican’s Synod Hall. It will be signed on 15 May, matching the date of the signing and publication of Rerum Novarum, Pope Leo XIII’s best-known encyclical, issued on 15 May 1891. The same date was also chosen in 1931 by Pope Pius XI for Quadragesimo Anno, which developed the Church’s teaching on social order and introduced the principle of subsidiarity. Thirty years later, on 15 May 1961, Pope John XXIII promulgated Mater et Magistra, focusing on economic justice and social development. The date of release, 25 May, also coincides with Pope John Paul II’s Ut Unum Sint, on ecumenism, which was released on 25 May 1995, and Pope Leo XIII’s Annum Sacrum, released on 25 May 1899, which consecrated the entire human race to the Sacred Heart of Jesus.

The Armenian Apostolic Church has said that Pope Leo XIV and Catholicos Aram I discussed the possibility of convening a “Third Vatican Council” during a private meeting at the Vatican focused on Christian unity, Artsakh and the Middle East The idea of convening a “Third Vatican Council” was discussed during a private meeting between Pope Leo XIV and Catholicos Aram I at the Vatican. The meeting took place on May 18 and focused on Christian unity, the plight of displaced Armenians from Artsakh, the continuing detention of Armenian prisoners in Baku and the situation in Lebanon. While the Vatican’s own account of the audience made no mention of a council, a statement released by the Armenian Apostolic Church said the two Church leaders discussed “the establishment of a common date for Easter, a day of commemoration for all martyrs, and the convening of a Third Vatican Council”. According to the statement, Aram I stressed the “urgent necessity” of such initiatives for the life of the “universal Christian Church”. The Armenian Church added that Pope Leo XIV expressed “understanding and support” concerning the issues raised during the meeting. No details were given about what form a Third Vatican Council might take or whether it would involve only the Catholic Church or a wider ecumenical gathering of Christian Churches. The Second Vatican Council, convened by Pope John XXIII in 1962 and concluded under Pope Paul VI in 1965, remains the most recent ecumenical council of the Catholic Church. Speculation about a future council has surfaced periodically in recent decades, though no pope has publicly advanced plans for another ecumenical council. The proposal emerged during a broader conversation between Leo XIV and Aram I concerning the condition of Christians in the Middle East and relations between Churches. According to the Armenian statement, Aram I also raised the issue of Artsakh and the right of displaced Armenians to return “under international guarantees”. He further stressed the need to protect Armenian churches and historical monuments in accordance with international law. The Catholicos additionally referred to the continuing detention of former Artsakh officials and political leaders held in Baku, saying their release remained an urgent matter. The meeting also addressed Lebanon, where Aram I underlined the importance of preserving the sovereignty of the Lebanese state and ensuring the authority of the government throughout the country. He also spoke of the importance of Israel withdrawing from southern Lebanon and respecting existing ceasefire agreements. The Armenian statement said the two Church leaders also discussed ecumenical relations and the future direction of inter-Church dialogue. Aram I emphasised that alongside theological discussions, “moral and ethical issues” should occupy a greater place within ecumenical cooperation and international Christian initiatives. The Vatican has sought closer ties with the Oriental Orthodox Churches since the Second Vatican Council, with relations between Rome and the Armenian Apostolic Church improving markedly during the pontificates of Pope St John Paul II, Benedict XVI and Francis. Pope Francis maintained warm relations with Armenian Christian leaders and frequently referred to the suffering of Armenian Christians in the Middle East. In 2015 he described the mass killing of Armenians under the Ottoman Empire as “the first genocide of the 20th century”. Aram I, who has led the Catholicosate of the Great House of Cilicia since 1995, has long been active in ecumenical affairs and previously served as moderator of the World Council of Churches.

The Vatican has confirmed the release date, title and theme of Pope Leo XIV’s first encyclical The release date for Pope Leo XIV’s first encyclical has been confirmed as May 25. The title of the document has been confirmed as Magnifica Humanitas, and it will focus on preserving the human person in the age of artificial intelligence, according to Vatican News. Although the text will not be released until May 25, it will be signed on May 15, matching the date of the signing and publication of Rerum Novarum, Pope Leo XIII’s best-known encyclical, issued on May 15, 1891. The same date was also chosen in 1931 by Pope Pius XI for Quadragesimo Anno, which developed the Church’s teaching on social order and introduced the principle of subsidiarity. Thirty years later, on May 15, 1961, Pope John XXIII promulgated Mater et Magistra, focusing on economic justice and social development. May 25 also coincides with Pope St John Paul II’s Ut Unum Sint, on ecumenism, which was released on May 25, 1995, and Pope Leo XIII’s Annum Sacrum, released on May 25, 1899, which consecrated the entire human race to the Sacred Heart of Jesus. Magnifica Humanitas will be presented at 11.30am in the Vatican’s Synod Hall. Alongside the Pope, a number of significant prelates, theologians and specialists are scheduled to speak. They include Cardinal Víctor Manuel Fernández, prefect of the Dicastery for the Doctrine of the Faith; Cardinal Michael Czerny SJ, prefect of the Dicastery for Promoting Integral Human Development; Prof Anna Rowlands, a theologian and professor at Durham University; Christopher Olah, co-founder of Anthropic and head of research on the interpretability of artificial intelligence; and Prof Leocadie Lushombo IT, professor of political theology and Catholic social thought at the Jesuit School of Theology at Santa Clara University in California. Closing remarks will be given by Cardinal Secretary of State Pietro Parolin, followed by an address and blessing by the Pope. Addressing artificial intelligence, the encyclical will build on recent Vatican interest in the subject. In January 2025, the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education issued Antiqua et Nova, a joint note on “the relationship between artificial intelligence and human intelligence”. The document said AI could bring “important innovations” but warned that it also carried the danger of deepening inequality, manipulating public opinion and expanding “the instruments of war well beyond the scope of human oversight”. It added that artificial intelligence “should not be seen as an artificial form of human intelligence, but as a product of it”, and insisted that it “should be used only as a tool to complement human intelligence rather than replace its richness”.

The Vatican and the United States Embassy to the Holy See have issued clarifications after Iranian media reports claimed Pope Leo XIV had personally granted a special honour to Iran’s ambassador to the Holy See The Vatican and the United States Embassy to the Holy See have both issued clarifications after Iranian media reports claimed that Pope Leo XIV had personally granted a special honour to Iran’s ambassador to the Holy See. Mohammad Hossein Mokhtari, the Iranian ambassador, was among 13 diplomats who received the Grand Cross of the Order of Pius IX during a ceremony held in the Vatican on May 12 for ambassadors who had completed at least two years of service accredited to the Holy See. Iranian state-linked outlets described the award as a significant gesture by the Pope towards Tehran, with some reports claiming the distinction recognised the ambassador’s efforts “to promote messages of peace, justice, and opposition to warmongering”. Iranian press suggested that “the award and the pope’s denunciation of the aggression are closely linked to the ongoing efforts of the Iranian embassy at the Vatican to promote messages of peace, justice, and opposition to warmongering”. The reports prompted criticism on social media and led to public clarification from both the Vatican and the American diplomatic mission to the Holy See. In a statement published online, the United States Embassy to the Holy See said: “Contrary to some reports, Pope Leo has not bestowed an exclusive special honour on the Iranian Ambassador to the Holy See. This decoration is given to all accredited ambassadors to the Holy See after 2+ years of service and has been standard practice for many years.” The Holy See press office confirmed the same account in comments to journalists, stating that the honour “is an award bestowed upon ambassadors after two years of service at the Holy See”. The Vatican added: “Yesterday, the Sostituto presented it to 13 ambassadors, including Iran’s ambassador.” The ceremony took place on the anniversary of Pope Leo XIV’s election and was presided over by Archbishop Paolo Rudelli, the substitute for general affairs of the Secretariat of State (Sostituto), who presented the insignia and official parchments to the diplomats. The certificates accompanying the awards were signed by Cardinal Pietro Parolin, the Vatican Secretary of State. The Order of Pius IX, also known as the Pian Order, is one of the principal papal orders of knighthood and is regularly conferred upon heads of state, royalty and ambassadors accredited to the Holy See. Although the Supreme Order of Christ and the Order of the Golden Spur formally rank above it, both honours have effectively fallen dormant. In practical diplomatic terms, the Order of Pius IX is regarded as the Holy See’s highest active distinction. The order was restored by Blessed Pius IX in 1847, though its origins date back to the 16th century under Pope Pius IV. Recent recipients have included King Charles III, who received the honour during his visit to the Vatican, as well as King Juan Carlos I of Spain, King Albert II of Belgium and King Carl XVI Gustaf of Sweden. Recipients of the Grand Cross wear a dark blue sash edged in red, together with a silver breast star bearing the insignia of the order. The original members of the order historically formed part of the papal lay court and accompanied the pope in ceremonial and official duties within the Apostolic Palace.

Cardinal Víctor Manuel Fernández, Prefect of the Dicastery for the Doctrine of the Faith, has released a statement warning that planned episcopal consecrations by the Society of St Pius X risk constituting “a schismatic act” Cardinal Víctor Manuel Fernández has warned that the Society of St Pius X risks committing “a schismatic act” through episcopal consecrations without papal approval, in the first public intervention since the meeting with the SSPX on 12 February. In a statement released by the Dicastery for the Doctrine of the Faith on 13 May, the prefect said the planned SSPX episcopal ordinations “do not have the corresponding pontifical mandate” and reiterated the penalties attached under canon law to such an action. “The episcopal ordinations announced by the Priestly Society of Saint Pius X do not have the corresponding pontifical mandate,” Cardinal Fernández said. “This gesture will constitute ‘a schismatic act’ (John Paul II, Ecclesia Dei , n. 3), and ‘formal adherence to the schism constitutes a grave offense against God and entails the excommunication established by Church law’ ( ibid ., 5c; cf. Pontifical Council for Legislative Texts, Explanatory Note , 24 August 1996).” The statement concluded: “The Holy Father continues in his prayers to ask the Holy Spirit to enlighten the leaders of the Priestly Society of Saint Pius X so that they retrace their steps regarding the very serious decision they have taken.” The intervention followed reports earlier on Wednesday morning by Vatican correspondent Nico Spuntoni in the Italian newspaper Il Giornale that the Dicastery for the Doctrine of the Faith was preparing a text concerning the Society and the limits of its relationship with Rome. While no formal canonical decree has yet been issued, Cardinal Fernández’s statement closely resembles the warning sent to Archbishop Marcel Lefebvre shortly before the episcopal consecrations at Écône in 1988. On 17 June 1988, Cardinal Bernardin Gantin, prefect of the Congregation for Bishops, issued a public canonical warning to Lefebvre after the French archbishop announced that he intended to consecrate four bishops without pontifical mandate. “Since on June 15, 1988 you stated that you intended to ordain four priests to the episcopate without having obtained the mandate of the Supreme Pontiff as required by Canon 1013 of the 1983 Code of Canon Law, I myself convey to you this public canonical warning,” Cardinal Gantin wrote. His Eminence continued: “If you should carry out your intention as stated above, you yourself and also the bishops ordained by you shall incur ipso facto excommunication latae sententiae reserved to the Apostolic See in accordance with Canon 1382.” The letter concluded with a direct appeal to Lefebvre “in the name of Jesus Christ” to reconsider what it described as a grave act against the unity of the Church. Furthermore, the statement’s citation of a 1996 explanatory note issued by the Pontifical Council for the Interpretation of Legislative Texts recalls one of the strongest Vatican texts ever published on the canonical status of the SSPX. The 1996 document stated that the 1988 consecrations represented “the consummation of a progressive global situation of a schismatic character” and said that “the whole Lefebvrian movement is to be held schismatic”. It added: “As long as there are no changes which may lead to the re-establishment of this necessary communion, the whole Lefebvrian movement is to be held schismatic, in view of the existence of a formal declaration by the Supreme Authority on this matter.” The explanatory note also addressed Catholics attending SSPX chapels and clergy belonging to the Society. It distinguished between occasional attendance at SSPX liturgies and what it called “formal adherence to the schism”. According to the document, such adherence involved “a free and informed agreement with the substance of the schism” together with an external manifestation of separation from ecclesial communion. The text said that in the case of SSPX priests and deacons “there seems no doubt that their ministerial activity in the ambit of the schismatic movement is a more than evident sign” of formal adherence. The SSPX was founded in 1970 by Archbishop Lefebvre, a former superior general of the Holy Ghost Fathers and one of the leading conservative critics of Vatican II. Tensions between the Society and Rome escalated throughout the 1970s and 1980s over liturgical reform, ecumenism, collegiality and religious liberty. The crisis culminated on 30 June 1988 when Lefebvre consecrated four bishops at Écône without papal approval. The Holy See responded by declaring that Lefebvre, Bishop Antônio de Castro Mayer and the four newly consecrated bishops had incurred automatic excommunication. Two days after the consecrations, Pope St John Paul II issued the motu proprio Ecclesia Dei adflicta , describing the consecrations as “a schismatic act”. Relations improved significantly under Pope Emeritus Benedict XVI. In 2009 he lifted the excommunications of the four bishops as part of an attempt to facilitate reconciliation, though the Society’s canonical status remained unresolved. Pope Francis later granted SSPX priests faculties to validly hear confessions during the Year of Mercy, later extending the provision indefinitely. Local bishops were also authorised under certain conditions to delegate SSPX priests to witness marriages. Despite those concessions, doctrinal discussions between Rome and the Society have remained stalled for years, particularly over the interpretation of Vatican II and the authority of post-conciliar reforms. The Vatican statement issued on Wednesday is the first direct intervention from the doctrinal dicastery since the 12 February meeting with SSPX superior Fr Davide Pagliarani, which the dicastery described as “cordial and sincere”. The DDF reiterated that the ordination of bishops without a mandate from the Roman Pontiff would entail “a decisive rupture of ecclesial communion”, namely “a schism”, with “grave consequences for the Society as a whole”, the dicastery noted. For that reason, it proposed suspending the episcopal ordinations announced for 1 July 2026, which had been declared without papal approval. However, the SSPX rejected the proposal in a communiqué and decided to proceed with the episcopal consecrations.
