The Vatican released the document 'Antiqua et Nova' in 2025 to address the relationship between artificial intelligence and human intelligence. The note aims to clarify the difference between the capabilities of technological power and genuine human intelligence. The document provides timely perspectives on the potential societal benefits of AI. It also highlights the moral risks associated with the rapid development of artificial intelligence. The concept of technology imitating or exceeding human mental capabilities is not a new idea, referencing 18th-century philosophy.

The Vatican's 2025 document ‘Antiqua et Nova,’ issued by the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education, examines artificial intelligence (AI) versus human intelligence amid rapid tech advances.1
This commentary marks its first anniversary, highlighting its relevance in distinguishing technological power from true human intellect.1
Ideas of machines mimicking human minds date to the 18th century with Julien de La Mettrie's view of humans as machines and early automatons.1
Alan Turing's 1950 test predicted computers could fool humans by century's end, while the 1956 Dartmouth workshop formalized AI principles like language use and neural simulation.1
AI progressed through "summers" of breakthroughs and "winters" of setbacks, never fully meeting Turing's standard.1
Neural networks, proposed in 1943 by McCulloch and Pitts, model brain neurons with interconnected nodes.1
Recent leaps stem from NVIDIA GPUs enabling deep learning on vast internet data, allowing AI to infer patterns autonomously beyond rigid programming.1
This shift gives AI a form of problem-solving resembling human reason, though loosely.1
AI excels in pattern matching but lacks genuine understanding, adaptation, or abstraction, as noted by experts like Ralph Lewis.1
‘Antiqua et Nova’ affirms human intellect's unique "intimate penetration of truth" per Thomas Aquinas, rooted in body-soul unity and divine likeness from Gaudium et Spes.1
Humans transcend material via the soul, grasping essences and meanings AI cannot.1
Human intelligence includes empathy, love, and communion, irreplaceable in relationships, education, and healthcare.1
The document warns against replacing humans with AI, emphasizing personhood's dignity amid tech hype.1
AI industry figures rarely apply Christian principles, underscoring the Church's guiding role.1
Advances highlight human exaltation, urging rediscovery of philosophical-theological traditions for ethical tech use.1
‘Antiqua et Nova’ provides timeless reference points for navigating AI's potentials and risks.1
Examine the Catholic Church’s theological criteria for AI ethics
The Catholic Church evaluates artificial intelligence (AI) through the unchanging lens of theological anthropology, prioritizing the inviolable dignity of the human person created in God's image and likeness. This dignity, rooted in humanity's vocation to divine beatitude, demands that AI serve as a tool enhancing rather than undermining personal fulfillment, moral growth, and relationship with God. Recent papal interventions by Pope Leo XIV emphasize that AI must be oriented toward the common good, integral human development, and reverence for life, reflecting the Creator's design where technology participates in divine creativity yet remains subordinate to ethical and spiritual imperatives. These criteria draw from Scripture, Tradition, and the Magisterium, linking AI ethics to broader social doctrine that insists on justice, solidarity, and the harmony between faith and reason.
At the heart of the Church's theological approach lies the dignity of the person, which precedes society and grounds all rights and moral legitimacy. AI, as a human invention, must respect this dignity, avoiding any reduction of the person to mere data or instrumentality. The Church reminds that true autonomy—whether individual or cultural—operates within moral limits and the common utility, affirming the legitimate liberty of sciences like AI while subordinating them to the pursuit of truth and the good. Pope Leo XIV underscores this in addressing AI developers: every design choice expresses a vision of humanity, calling for systems that reflect justice, solidarity, and genuine reverence for life.
This criterion counters secular views that exaggerate human autonomy apart from God, as atheism often does by denying dependence on the Creator. Instead, dignity finds perfection in God, harmonizing with the heart's deepest desires. In the AI context, Pope Leo XIV warns of an "eclipse of the sense of what is human," urging evaluation of AI's benefits and risks against the integral development of the human person and society—materially, intellectually, and spiritually. Particular concern arises for children and youth, whose maturity and God-given gifts must not be hindered by AI's influence on intellectual and neurological development. Access to vast data via AI cannot substitute for authentic intelligence, which involves openness to life's ultimate questions and orientation toward the True and Good.
Theologically, AI emerges from the creative capacity God entrusted to humanity, akin to dominion over the earth, making technological innovation a form of co-creation. Yet this participation carries ethical and spiritual weight, as tools derive their moral force from human intentions. Pope Leo XIV frames AI not merely as capability but as shaping "who we are becoming," demanding moral discernment to ensure it fosters evangelization, compassionate healthcare, and truthful storytelling rather than conflict or selfish gain.
This echoes Vatican II's vision: the Church casts divine light on human endeavors, elevating personal dignity and infusing society with deeper meaning. Christ remains the key to the mystery of man amid modern progress and sorrows, offering light for humanity's supreme destiny. AI must thus align with unchanging realities founded in Christ, avoiding paradigms that prioritize technology over relationality, love, and freedom in God. The Latin American Episcopal Council (CELAM) highlights AI's transformative impact on work, culture, faith, and society, stressing the need to consider its anthropological and ethical implications as advancing rapidly.
Catholic criteria for AI integrate life issues with social justice, rejecting compartmentalization. As Pope Benedict XVI taught, Humanae Vitae reveals strong links between individual morality (unitive-procreative sexuality) and societal development, ushering in teachings like Evangelium Vitae. AI ethics must similarly connect to protecting life from conception, countering a "throwaway culture" through new economic and lifestyle paradigms. Environmental ecology depends on human ecology, prioritizing duties over rights.
In social doctrine, the Church intervenes in conflicts like those between capital and labor, applying Gospel principles to earthly realities. AI governance must promote solidarity and unity, aiding intergenerational formation where youth integrate truth into moral and spiritual life. Public authority fosters culture without dominating it, preventing AI from serving domination.
The Church's role is prophetic: to evangelize the "world of the media" and AI itself, treating it as a new forum reflecting and creating culture. Pope Leo XIV calls AI development a profoundly ecclesial endeavor, fostering interdisciplinary communities for the Church's mission via faith-reason dialogue. This mirrors the Church's contribution to humanizing history, esteeming collaborative efforts while preparing Gospel ground through human talents.
The Church's theological criteria for AI ethics—anchored in human dignity, participatory creation, integral development, ethical integration, and evangelization—ensure technology serves the human family under God's providence. Pope Leo XIV's recent messages, building on conciliar and encyclical foundations, affirm AI's potential as hope when guided by love, wisdom, and reverence. Developers and users are called to moral discernment, placing intelligence at the service of relational truth.
