Neanderthals could speak

 



“As well as archaeological artefacts, researchers also point to similarities

in their vocal anatomy with modern humans and their known cognitive abilities. Neanderthals had larger brains, on average, than modern humans and while

this doesn’t mean they were necessarily smarter, it does suggest they were

a highly intelligent species - just like us”.

New Shocking Discovery About Neanderthals Changes EVERYTHING!

 

Recent discoveries have revealed that Neanderthals and Homo sapiens in the mid-Middle Paleolithic Levant not only coexisted but actively interacted, sharing technology, lifestyles, and burial customs. These interactions fostered cultural exchange, social complexity, and behavioral innovations, such as formal burial practices and the symbolic use of ochre for decoration. The findings suggest that human connections, rather than isolation, were key drivers of technological and cultural advancements, highlighting the Levant as a crucial crossroads in early human history.

They interbred – but could humans and neanderthals actually talk to each other?

 

Our ancestors lived alongside Neanderthals for nearly 200,000 years [sic], often interbreeding with them. But could they understand one another?

We might be the only species of human alive today, but just a few hundred thousand years ago [sic] there were a handful of different species living across the world.

 

The Neanderthals were one of these species, and … they’re our closest cousins.

 

….

 

How closely related are we to Neanderthals?

 

It was long thought that we (Homo sapiens) evolved from Neanderthals (Homo neanderthalensis) and that these stocky ‘almost-humans’ were a transitional phase between chimpanzees and modern humans. This ‘March of Progress’-style image is often how our evolutionary history is depicted, but it couldn’t be further from the truth.

 

 

Instead, modern humans and Neanderthals are sister species that evolved from the same common ancestor [sic], diverging from one another roughly half-a-million years ago. As a species, Neanderthals emerged earlier than modern humans, roughly 400,000 years ago compared to 300,000 years ago, but it wasn’t until 130,000 years ago that ‘classic Neanderthals’ really appeared.

….

Regardless of who this common ancestor was, genetic studies show that Neanderthals are our closest relatives and share up to 99.7% of our DNA. These similarities run so deep that some suggest Neanderthals may actually represent a subspecies of Homo sapiens and should be renamed Homo sapiens neanderthalensis.

 

Could Neanderthals speak?

 

The linguistic ability of Neanderthals has long been debated. From their discovery in the mid 19th century until quite recently, they were often portrayed as dim-witted ‘cavemen’, their communicative abilities thought to be limited to grunts and simple gestures.

….

 

It’s clear from the wealth of archaeological artefacts left by Neanderthals alone that this was simply not the case. The discovery of clothes, jewellery, weapons, and sophisticated homes crafted by Neanderthals paint a picture of people who could not only communicate, but collaborate and even create art.

 

As well as archaeological artefacts, researchers also point to similarities in their vocal anatomy with modern humans and their known cognitive abilities. Neanderthals had larger brains, on average, than modern humans and while this doesn’t mean they were necessarily smarter, it does suggest they were a highly intelligent species - just like us.

 

In order to find out just how well Neanderthals could speak, a team of researchers from the University of Iowa examined their genetic code for genomic regions known as ‘human ancestor quickly evolving regions’, or HAQERS. These aren’t genes, rather sequences that affect how and when certain genes are expressed, and they’ve been shown to have a large effect on human language development.

 

What these researchers found as part of a study published in April, 2026, surprised them. Neanderthals not only had HAQERS, but they were even more prominent than those found in humans today ….

 

If that was the case, and Neanderthals were capable of language, surely they could have found ways to communicate with the humans they bumped into - right?

 

Could humans and Neanderthals communicate?

 

It’s clear, based on the genetic evidence, that humans and Neanderthals regularly ‘bumped’ into one another - in more ways than one…

 

In 2010, researchers successfully sequenced the Neanderthal genome and discovered that modern humans of non-African descent carry roughly 2% Neanderthal DNA in their genomes. Some populations carry even more: the proportion in East Asian populations can be as high as 4%!

 

This genetic evidence proves that humans and Neanderthals interbred quite regularly, and suggests some may have even lived together in mixed groups. The individuals living in these mixed groups, nurturing and raising hybrid offspring, must have been able to communicate to some degree. ….

 

One Nation’s Barnaby Joyce fires up anti-abortion rally

Riding high on One Nation’s popularity in the polls, backbench MP Barnaby Joyce has fronted an anti-abortion rally with a fiery warning to other politicians.

 

Joyce said his pro-life stance was one of conviction rather than of political opportunism, drawing massive cheers from a crowd of about 2000 people outside the NSW parliament on a chilly Sydney evening.

“Politically, does this make you popular? No, you’d probably lose half your votes every time you do it. But you know why you do it because that’s the right thing to do,” he said.

 

Joyce, who left the Nationals in late 2025 as the far-right One Nation’s polling rise gathered pace, argued that galvanising support around the pro-life cause could change the political landscape.

 

One Nation has leapfrogged Labor to become the political party with the highest primary vote, according to a Redbridge poll this week.

 

“I don’t know much about a lot, but I know a lot about politics and the one thing politicians fear is losing their job. They’re very mindful of that,” Joyce said.

“You must keep that fire burning for those people who can’t stand up for themselves and I call them people – they’re not foetuses.”

Tuesday’s demonstration was organised by anti-abortion campaigner Joanna Howe in support of a bill in NSW parliament proposed by Libertarian MP John Ruddick to criminalise gender selective abortions.

King Louis XIV of France and Consecration to the Sacred Heart of Jesus

 

 


In June 1929, the Fatima seer Lucia received another vision in which Our Lord

told her, “Like the king of France, they will repent and do it, but it will be late. Russia will have already spread her errors throughout the world, provoking wars and persecutions of the Church; the Holy Father will have much to suffer”.

  

Consecration to the Sacred Heart of Jesus – Miles Jesu

 

Consecration to the Sacred Heart of Jesus

 

Fr. Christopher Foeckler, MJ • St Josaphat Formation Center, Phoenix, AZ

 

A little known fact of the revelations of the Sacred Heart to St. Margaret Mary is that in 1689 Jesus asked that the King of France consecrate himself and his realm to the Sacred Heart and that he adorn his flags and coat of arms with the image of His Heart. He was promised as a result to be victorious over his enemies and those of the Holy Church. The King at that time was none other than Louis XIV ‘the Sun King’ who, in spite of his many personal sins, was quite devout according to historians. He had, in fact, consecrated the realm to St. Joseph only three days after ascending to the throne some 45 years previously.

 

But this request of the Sacred Heart went unfulfilled by him and by his son Louis XV as well. It wasn’t until more than 100 years after the revelation to St. Margaret Mary of Our Lord’s special request that the French King – the unfortunate Louis XVI – made a private consecration of himself and the realm to the Sacred Heart of Jesus in 1792.

 

But it was too late. Louis XVI made this consecration privately as a prisoner in his own palace under the guard of the French Revolutionaries who ended his monarchy and sought his blood in the Terror that reigned in Paris.

 

Louis had vowed to make the consecration publicly when he would be restored to power, but the guillotine dashed all hope of that when he and his wife, Marie Antoinette, were executed.

 

Even though the kings of France had been reluctant to consecrate themselves to the Sacred Heart, many others were not, and the devotion spread within France and to other political powers of Europe with very positive results. Yet, one can wonder what would have happened if the Sun King had humbled himself and consecrated his realm to Jesus’ Heart?

 

The rest of the story, as they say, is that in June 1929, the Fatima seer Lucia received another vision in which Our Lord told her, “Like the king of France, they will repent and do it, but it will be late. Russia will have already spread her errors throughout the world, provoking wars and persecutions of the Church; the Holy Father will have much to suffer.”

 

Don’t hesitate to inform yourself and then consecrate yourself and your families to the Sacred Heart of Jesus and the Immaculate of Heart of Mary. St. Margaret Mary said, “The most efficacious way to obtain devotion to the Sacred Heart of Jesus is through the Immaculate Heart of Mary.”

The Angel of Fatima

 



The angel also identifies himself specifically as the guardian angel of Portugal, hearkening back to St. Michael’s role as prince and guardian of Israel

in the book of Daniel”.

 

Fr. John Horgan

 

  

The Angel of Fatima, a Messenger of Peace - Catholic Exchange

 

The Angel of Fatima, a Messenger of Peace

 

18 May 2018

- By Fr. John Horgan

 

The apparitions of the Blessed Virgin, Our Lady of the Holy Rosary, at Fatima in 1917 are not only one of the most important events in the Church in the twentieth century, but also one of the greatest Mariophanies in the life of the Church. Because of the spiritual movements that arose from these appearances, a tremendous wave of prayer, devotion, writings, and spiritual works of all kinds spread across the globe.

 

Pope St. John Paul II was unquestionably “the Pope of Fatima,” who believed that the personal and historic events of his reign — from his shooting to the fall of Communism in the Soviet Union and beyond — were inextricably linked to the messages of the Mother of God and the secrets she entrusted to the children she appeared to.

 

Angel of Peace

 

One of the secrets they kept, however, regards not the Virgin’s words, but the appearances of the “Angel of Peace,” who came to the children three times in the years before the Virgin’s first appearance and who made a profound impression upon their minds and hearts. These apparitions offered a catechesis of grace and sacrifice that disposed Lucia, Jacinta, and Francisco to receive the coming of the Holy Virgin and her message with a depth of commitment and maturity that far exceeded their years or education.

 

Lucia did not speak about these appearances at all until 1924, and Sts. Jacinta and Francisco never did so at all before their deaths.

 

Though Lucia confided in a priest about the angel’s visits, she was advised not to speak about them, lest they confuse the importance of Our Lady’s words. It was only in her 1937 memoir that she revealed their story in full.

 

The first appearances took place in 1915, when Lucia and two other girls saw a white transparent figure appear in the sky at the Cabeço — a secluded hillside — not far from their homes. The figure was of natural height, but seemed like a brilliant snow-white statue made of cloud. Though they saw this figure on three occasions, they did not reveal the experience to anyone.

 

In the spring of 1916, Lucia and her two cousins, Jacinta and Francisco, were tending their sheep at the Loca do Cabeço and had just finished their shortened version of the Rosary. A figure approached them through the sky coming from the east — a trans­parent, luminous figure of a youth of perhaps fourteen or fifteen years. The children were amazed and overwhelmed by what Lucia would describe as the “supernatural atmosphere” that penetrated and surrounded them. As she recounts in her memoir, the angel spoke to them words of reassurance and authority:

 

“Do not be afraid! I am the Angel of Peace. Pray with me.”

 

Kneeling on the ground, he bowed down until his forehead reached the ground. Led by a supernatural impulse, we did the same, and repeated the words which we heard him say:

 

“My God, I believe, I adore, I hope and I love Thee! I ask pardon of Thee for those who do not believe, do not adore, do not hope and do not love Thee!”

 

Having repeated these words three times, he rose and said:

 

“Pray thus. The Hearts of Jesus and Mary are attentive to the voice of your supplications.”

 

Then he disappeared.

 

The children remained with their heads bowed to the ground for some time, filled with this supernatural splendor. The prayer that they heard, now commonly called the Angel’s Prayer, remained fixed in their minds; Lucia said they often knelt with their heads on the ground, repeating this prayer for long periods of time.

 

This first message has many rich graces for us to consider: The angel reveals himself as the “Angel of Peace” in the midst of the First World War, but the peace that he comes to bring is based in union with God and intercession for others. His words call us back to the greatest commandments of the Old Law: total and complete love of God and neighbor.

 

The prayer he entrusts to them is brief, but it expresses both adoration and intercession in a posture of total reverence: kneeling and with forehead touching the ground. It is a gesture that the children understood and that they imitated constantly.

 

The Angels’s Second Appearance

 

The second apparition took place in the summer, after the children had pastured their sheep in the morning. Then, in the heat of the afternoon while they were playing quietly in the shade by the well near Lucia’s house, the angel appeared suddenly and said:

“What are you doing? Pray, pray very much! The Holy Hearts of Jesus and Mary have designs of mercy on you. Offer prayers and sacrifices constantly to the Most High.”

Lucy asked: “How are we to make sacrifices?”

 

“Make of everything you can a sacrifice, and offer it to God as an act of reparation for the sins by which He is so offended, and in supplication for the conversion of sinners. You will thus draw down peace upon your country. I am its Angel Guardian, the Angel of Portugal. Above all, accept and bear with submission the suffering which the Lord will send you.”

 

The angel’s first words are abrupt and echo the Lord’s voice to Elijah on Mount Horeb:

 

“What are you doing, Elijah?” (see 1 Kings 19:9–13).

 

Yet they are immediately followed by reassurance and strength. Once again, the angel speaks of the Hearts of Jesus and Mary, but this time he does not call them “attentive” to the children, but rather he says that Christ and His Mother have “plans of mercy” for them — a suggestion of an upcoming mission.

 

Then the angel speaks of sacrifices, both those voluntarily undertaken and those the Lord will send to the children. The sacrifices that they generously take upon themselves will serve as reparation for sins, contribute to the conversion of sinners, and bring about peace for the nation. These are weighty responsibilities to give to the three children.

And the angel points out too that the greatest sacrifice of all is the sacrifice of our own will, through acceptance and willing submission to God’s plan.

These are words on which we must meditate, just as the children did. They cannot simply be heard; rather, we must listen to them with open and trusting heartsLet us pray: “Jesus, I want what You want for me.

 

The angel also identifies himself specifically as the guardian angel of Portugal, hearkening back to St. Michael’s role as prince and guardian of Israel in the book of Daniel.  …. The question of the angel’s identity has not been answered ….

 

The Angel’s Final Apparition

 

The third and final apparition of the angel is the most extraordinary of all, since it is focused on the mystery of the Holy Eucharist. While other saints and blesseds have received Holy Communion from the hands of an angel (St. Bonaventure, St. Stanislaus Kostka, St. Paschal Baylon, St. Mary Frances of the Five Wounds, Blessed Marguerite Bays, and others), the Communion of the children of Fatima would seem to have an added ecclesial significance in keeping with the importance of their whole mission:

 

The third apparition must have taken place in October, or towards the end of September, as we were no longer returning for siesta.

After our lunch, we decided to go and pray in the hollow among the rocks on the opposite side of the hill. To get there, we went around the slope, and had to climb over some rocks above the Pregueira (south of the Loca do Cabeço). The sheep could only scramble over these rocks with great difficulty. As soon as we arrived there, we knelt down with our foreheads touching the ground, and began to repeat the prayer of the Angel:

 

“My God, I believe, I adore, I hope and I love Thee . . .”

 

I don’t know how many times we repeated this prayer, when an extraordinary light shone upon us. We sprang up to see what was happening, and beheld the Angel.

 

He was holding a chalice in his left hand, with the Host suspended above it, from which some drops of Blood fell into the chal­ice. Leaving the chalice suspended in the air, the Angel knelt down beside us and made us repeat three times:

 

“Most Holy Trinity, Father, Son and Holy Spirit, I offer Thee the most precious Body, Blood, Soul and Divinity of Jesus Christ, present in all the tabernacles of the world, in reparation for the sacrileges, outrages and indifferences by which He Himself is offended. And through the infinite merits of His Most Sacred Heart, and the Immaculate Heart of Mary, I beg of Thee the conversion of poor sinners.”

Then, rising, he took the chalice and the Host in his hands. He gave the Sacred Host to me, and shared the Blood from the chalice between Jacinta and Francisco, saying as he did so:

 

“Take and drink the Body and Blood of Jesus Christ, horribly outraged by ungrateful men! Make reparation for their crimes and console your God.”

 

Once again, he prostrated on the ground and repeated with us, three times more, the same prayer: “Most Holy Trinity . . .” and then disappeared.

Moved by a supernatural force which enveloped us, we had imitated the Angel in everything; that is, we prostrated as he did and repeated the prayers that he said. . . . We remained a long time in this position, repeating the same words over and over again. It was Francisco who realized that it was getting dark, and drew our attention to the fact, and thought we should take our flocks back home. I felt that God was in me.

 

The Eucharistic prayer that the angel teaches the children is a magnificent summary of the Catholic Faith: It speaks to us first of the Trinity; then it summarizes, almost like a catechism, the definition of the Real Presence of Jesus in the Eucharist; then it moves us to offer Christ to the Father, accepting His Passion for our sake and uniting our will to His will as an act of expiation and reparation; and finally it turns us to the very core of His redeeming love, his Sacred Heart, always united to His Mother’s pierced Heart for the salvation of sinners.

 

The angel offers this prayer in preparation for the children’s Communion and as the most fitting thanksgiving thereafter.

 

We too can benefit greatly from this prayer, receiving it as a gift from Heaven and incorporating it into our own Eucharistic Communions.

 

The children see the Host bleeding into the chalice, a visual image that unites the two Species and links this extraordinary re­ception of the Eucharist to the Sacrifice of the Cross and its renewal upon the altar. Lucia has already received her First Holy Commu­nion in the parish church of Fatima, so she is accustomed to the reception of Holy Communion. Francisco and Jacinta have not yet received their First Communion, but are communicated with the Precious Blood from the chalice. This first mystical union with Christ affected the children profoundly, leaving them in a state of joy, silence, and exhaustion.

 

In the third apparition, the presence of the Angel was still more intense. For several days, even Francisco did not dare to talk. He said later on: “I love to see the Angel, but the trouble is that later on, we are incapable of doing anything. I could not even walk any more. I didn’t know what was the matter!”

 

It was a grace so sublime, and so intimate, that Francisco, all absorbed in God, did not have a clear consciousness of the mystical grace that he had received and felt in a confused way. Once the first few days were over, and we had returned to normal, Francisco asked: “The Angel gave you Holy Communion, but what was it that he gave to Jacinta and me?” “It was Holy Communion, too,” replied Jacinta, with inexpressible joy. “Didn’t you see that it was the Blood that fell from the Host?” Francisco replied: “I felt that God was within me, but I did not know how!”

 

Though Francisco could not articulate his experience as clearly as the others, his words reflect the truth and beauty of what he felt, with all the candor and simplicity of a child.

We know that he never heard the words of the angel — nor, later, the words of Our Lady — but rather he depended on Lucia and Jacinta to repeat them to him.

 

But he did see the angel with the Host and the chalice, and he shared in the others’ adoration and prayer; this was enough to prepare him for this moment of union with Christ the Savior.

 

Why did the two younger children receive their mystical First Communion from the chalice rather than with the Host? Perhaps this was because the chalice is a biblical image of suffering, both in the Old Testament and the New.

 

Sharing in the Blood of Christ — drinking of His chalice — is a sign of willingness to undergo martyrdom for the sake of His Name. Jacinta and Francisco were both destined to die at a very early age, and both offered their sufferings consciously and courageously to the Lord, as the angel had taught them. Jacinta was drawn to reparation for sinners, while Francisco spent many hours of the day in their parish church, “consoling God.”

 

Now, from their place in Heaven they have become evangelizers, teaching us to do good with all our sufferings — and to do good toward those who suffer. The prayers they learned from the angel can be taught to the great and the small, the young and the old. In them we find a message from Heaven to each of us. Through such prayers and the generous offering of our own sacrifices, may we come to share in this life in the wonder, reverence, and joy that the children of Fatima experienced. And may we one day be their companions in Heaven!

Pope Leo recalls the Tower of Babel, and Nehemiah, for his first encyclical

amid rapid technological advances, a fractured global landscape and

accelerating threats to human life and dignity”.

Babel, Nehemiah and algorithms: A guide to key terms in Pope Leo’s new encyclical on AI

 

written by Gina Christian 5:31 AM May 25, 2026

 

(OSV News) — What do the Tower of Babel, the biblical figure Nehemiah, algorithms and realpolitik have in common?

 

They’re all discussed — along with integral human development, the technocratic paradigm and Catholic social teaching — in Pope Leo XIV’s first encyclical, “Magnifica Humanitas: On Safeguarding the Human Person in the Time of Artificial Intelligence.”

 

This is Pieter Bruegel’s 1563 painting of the "Tower of Babel." In "Magnifica Humanitas," Pope Leo XIV writes that humanity "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 highly anticipated text, signed by the pope on May 15 and released May 25, invokes the wisdom of the Church’s social teaching as a framework for shaping AI amid rapid technological advances, a fractured global landscape and accelerating threats to human life and dignity.

 

Here’s a guide to some of the terms discussed in the document.

 

  • Artificial intelligence: An umbrella term for technology that emulates human intelligence. The ability to learn from data, recognize patterns, solve problems, make decisions and generate original content from human prompts are all features of AI. 


In “Magnifica Humanitas,” Pope Leo writes that “it is not possible to provide a single, comprehensive definition of AI.”

“What can be stated, however, is that we must avoid the misconception of equating this type of ‘intelligence’ with that of human beings,” he continued.

 

“These systems merely imitate certain functions of human intelligence. In doing so, they often surpass human intelligence in speed and computational capacity, offering tangible benefits across many fields. Yet this power remains entirely tied to data processing.”  

AI is programmed in several computer languages, among them Python, C++, Java and R. Everyday examples of AI in action include various types of chatbots such as OpenAI’s ChatGPT and Anthropic’s Claude, online product recommendations and virtual personal assistants like Amazon’s Alexa and Apple’s Siri. AI has a range of business applications across almost all market sectors, including healthcare, education, energy and security.

  • Algorithm: In essence, a routine, step-by-step process for accomplishing a task. AI algorithms, which are more complex, are designed to cover multiple “what ifs?” in a given situation, and to learn from data on which they are trained. Pope Leo cautions in his encyclical that AI algorithms can be used to exert dominance over the vulnerable and over humanity itself, while eroding responsibility and empathy.

    “From this follows a simple but compelling consequence: we cannot consider AI to be morally neutral,” he writes. “In reality, every technical tool embodies choices and priorities through what it measures, ignores and optimizes, and how it classifies people and situations.”

  • Alignment: In AI development, the process of ensuring the technology squares with human values, so that AI models safely serve human interests. “Emergent misalignment,” where AI deviates from such norms and behaves detrimentally, is a growing concern among AI ethicists and theologians. Pope Leo insists that alignment come with a further condition: “the possibility of openly discussing the ethical frameworks involved and subjecting them to shared standards of social justice.

Otherwise, those who control AI will impose their own moral vision, which will become the invisible infrastructure of these systems.”

  • Babel, Tower of Babel: Described in Genesis 11:1-9, the city and tower built by the nations of the earth in the valley of Shinar, after Noah and his family survived the flood. Because the nations, which spoke the same language, undertook the project in human pride, the Lord confused their speech, leading to division and dispersion across the earth. In section seven of his encyclical, Pope Leo uses this example to show “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.”

  • Catholic social teaching (social doctrine): The Church’s teaching — which draws on papal, conciliar and Church documents — on the means of building a just society and living out holiness in modern life. As Pope Leo explains in his encyclical, the term was coined by Pope Pius XII in 1950, but owes its development to “a long tradition of ecclesial reflection on life in society, rooted in Sacred Scripture, the Church Fathers and the theological and legal developments of the Middle Ages and modern era.”  Pope Leo also notes that his “beloved predecessor” Pope Leo XIII propelled that tradition toward modern applications in his 1891 encyclical “Rerum Novarum.”

    Key principles of Catholic social teaching are the common good; the universal destination of goods, which holds that the goods of creation are meant for all (even when private property is justly acquired); subsidiarity, which stresses that society’s larger institutions, including the state, should not overwhelm or interfere with smaller ones (including families and Church communities); solidarity, which holds that humanity, even with its differences, is a family; and justice, which the Catechism of the Catholic Church says “consists in the constant and firm will to give their due to God and neighbor.”

    In his encyclical, Pope Leo stresses that AI and its attendant power must be assessed against the principals of Catholic social teaching.

  • City of God, city of man: Symbols, respectively, of faith in God and unbelief. The two are contrasted by St. Augustine in his work best known as “The City of God.”

 

In his encyclical, Pope Leo (a member of the Order of St. Augustine who regularly invokes the saint’s thought) cites the image and quotes St. Augustine’s observation that “two loves have built two cities: the earthly city, the love of self even to the contempt of God; the heavenly city, the love of God even to the contempt of self.” Pope Leo then reflects, “As throughout history, these two loves continue to contend for dominance in our hearts today. The age of AI is no exception: the construction of Babel or the rebuilding of Jerusalem begins within each one of us.”

§   Ecology of communication: A model for understanding the dynamic between communications and the social order. The concept, sometimes called “media ecology,” traces its roots to communications scholarship from the 1960s. In his encyclical, Pope Leo uses the term in calling for, among other things, transparency in Church communications, personal data protection and content selection; digital and media literacy; serious journalism; information verification; and the enhancement of critical thinking skills. Pope Leo notes that such actions reflect “the fundamental principle” that “truth is a common good and not the property of those with power and influence.”

 

§   Integral human development: A term found in St. Paul VI’s 1967 encyclical “Populorum Progressio” that views the flourishing of individuals and peoples holistically — taking into account spiritual, cultural, moral and relational concerns, with an eye not only to present but future generations.

 

The concept is central to Catholic social teaching (see above), with Pope Francis establishing the Vatican’s Dicastery for Promoting Integral Human Development in 2016. In his encyclical, Pope Leo describes integral human development as “the framework through which we can interpret the changes of our time, including those brought about by the digital revolution.”

  • Large language model: A type of AI model capable of being trained to understand and generate language in a human-like way, with context and nuance.

  • Multilateralism: In international relations, the concept of cooperation among diverse nations. Originally a geometry term for “many-sided,” multilateralism is central to entities such as the United Nations, and to international agreements on a rules-based order that safeguards human life and dignity. In his encyclical, Pope Leo points to a crisis in the current multilateral system, not only due to “structural limitations” but to “a frequent lack of shared will to support and reform them, or to recognize their moral authority.” 
    He observes that the economic globalization following the collapse of Europe’s communist regimes in 1989 is far from “genuine multilateralism.” Instead, he writes globalization’s “almost blind faith in markets” has “provoked fundamentalist, identity-based and nationalistic reactions” and devolved into “a disorderly and conflict-ridden multipolarism with a prevailing sense of mistrust.” Shared efforts for a common good are further imperiled by reemerging attempts to “forge a collective identity in opposition to an enemy,” with each side claiming itself to be “a victim entitled to retribution” and replacing international law with the claim that “might makes right.” As a result, warns Pope Leo, power politics are sidelining peacebuilding initiatives and compromising “the achievements of humanitarian law,” with protections for civilians and “especially children” amid conflict “regarded as naïve relics of the past.”

 

  • Nehemiah: Both the name of the governor of Judah and the book found in the Bible. In about 444 B.C., Nehemiah was granted permission from Persian King Artaxerxes I to return to Jerusalem — where some Jews, following the sixth-century B.C. Babylonian exile, had begun to resettle — in order to rally and direct the people in a shared restoration of their ancient city. Unlike Babel, said Pope Leo in his encyclical, this effort under Nehemiah (and later under Ezra) placed “God at the center” and prioritized “communion” and “rebuilding relationships” over “uniformity.”

  • Political realism, realpolitik: Political realism is a political theory that prioritizes power over morals and ethics, effectively holding that “might makes right.” In international relations, realpolitik (a term first popularized in the 19th century) also privileges power, as well as national interest, over other principles and considerations, framing it as pragmatic politics. In his encyclical, Pope Leo warns that both philosophies — the latter of which he condemns as “truly irresponsible” — work to present war as inevitable, thereby precluding genuine peace based on justice and charity.

  • Technocratic paradigm: A term also used by Pope Francis in his 2015 encyclical “Laudato Si'” to describe a worldview in which humanity employs technology with the guiding aim of “possession, mastery and transformation,” rather than the humble, grateful stewardship of God’s abundant gifts.

 

Pope Leo writes that this “pervasive technocratic paradigm … amplified by the digital revolution and AI, threatens to normalize an anti-human vision. In that vision, the fullness of life is equated with having more, reducing weakness, eliminating uncertainty and exerting total control.

 

When efficiency becomes the ultimate measure of value, human beings are tempted to see themselves as a project to be optimized rather than as persons called to relationship and communion.”

  • Transhumanist, posthumanist: Transhumanism holds that humans can transcend their limitations particularly through scientific advances such as computer technology, cryonic preservation, biomedicine and other technological interventions. Posthumanism counters the view that humans are central, with some posthumanists advocating a hybridization of humans, machines and the environment.

    “Even when such ideas remain largely speculative, they gain relevance by altering the collective imagination and thereby influence social, economic and political choices,” Pope Leo writes in his encyclical.

He contrasts these views with the Christian understanding of humanity as created by God, noting that human limitations are vital opportunities to “recognize the inviolable dignity of every person,” live with compassion and “encounter the presence of the Lord.”
