Pope Leo XIV sent a message for the International Day of Mathematics urging attention to the moral dimension of emerging technologies. The message, addressed to Professor Betül Tanbay, emphasized that extensive knowledge is insufficient without understanding self-identity and life's meaning. The Pope suggested that research into the use of algorithms, especially in artificial intelligence, is a fruitful area for consideration. He stressed that addressing the moral dimension of new technologies requires not only intellectual effort but also the integral growth of the whole person.

Pope Leo XIV sent a message on March 13, 2026, for the International Day of Mathematics, addressed to Professor Betül Tanbay via Cardinal Pietro Parolin.1 2
The message greeted participants in a webinar themed “Mathematics and Hope,” amid humanity's challenges like rapid technological development.1 2
The Pope urged attention to the moral aspects of technologies, especially AI algorithms.1 2
He stressed that intellectual effort alone is insufficient; it requires integral personal growth to address these technologies' potential for good or evil.1 2
Pope Leo XIV, formerly Robert Francis Prevost, taught mathematics and physics, drawing from this experience in his message.1 2
He recalled telling students during the 2025 Jubilee of Education: vast knowledge is not enough without understanding one's identity and life's meaning.1 2
Prevost earned a mathematics degree from Villanova University in 1977 and taught at Chicago high schools.2
Mathematicians should be “signs of hope” by humanizing the digital sphere for fraternity and creativity.1 2
The Pope encouraged attentiveness to spiritual needs and acting as prophets of hope, truth, and goodness.1 2
He invoked blessings of wisdom, joy, and peace on participants.1 2
Investigate Catholic teachings on morality in emerging technologies
Catholic moral teaching on emerging technologies, particularly artificial intelligence (AI), robotics, and related innovations, centers on the inherent dignity of the human person as the foundational criterion for their development and use. Technology must always serve the common good, promote integral human development, and remain under human control, avoiding any risk of dehumanization or domination over life. Drawing from Scripture, the Catechism, conciliar documents, and recent papal magisterium, the Church views these technologies as expressions of God's gift of creativity to humanity but warns against illusions of moral neutrality or unchecked progress.
The Church's social doctrine posits that science and technology are "precious resources" when ordered to the human person, but they "cannot disclose the meaning of existence" on their own. They must respect "fundamental moral criteria" and conform to God's plan, rejecting any claim to moral neutrality.
"The inherent dignity of every human being must be firmly placed at the centre of our reflection and action."
This echoes Gaudium et Spes (GS 26, 34-35), which affirms human dominion over creation while subordinating technology to moral values. Pope Francis emphasized that AI touches "the very threshold of the biological specificity and spiritual difference of the human being," declaring "the distinctiveness of human life... an absolute good." Pope Leo XIV reinforces this: humans are "co-workers in the work of creation," with dignity in free choice, love, and relationships—qualities AI cannot replicate.
The Catechism of the Catholic Church (CCC) integrates this into the moral life: true beatitude lies not in technological achievements but in God alone (CCC 1723), and media/tools demand vigilant, disciplined use to form consciences (CCC 2496).
Emerging technologies like AI are "tools" derived from human creativity, a participation in divine creation (cf. Ex 35:31). However, they are "qualitatively distant from the human prerogatives of knowledge and action," lacking conscience, emotionality, or moral autonomy.
"Artificial devices that simulate human capabilities are devoid of human quality."
Antiqua et Nova (2025) clarifies: AI performs "servile tasks" via algorithms but cannot make ethical decisions; "decision-making… must always be left to the human person." Pope Francis at the G7 warned against attributing "properly human" capacities to machines, risking "man being 'technologized', rather than technology humanized." Pope Leo XIV echoes: AI springs from God-given creativity but every design choice expresses a "vision of humanity," demanding moral discernment.
In medicine, AI must enhance—not replace—human relationships: "technological devices must never detract from the personal relationship between patients and healthcare providers."
The Church identifies profound moral perils:
Dehumanization and Bias: AI risks imposing "uniform anthropological models," incorporating prejudices via data (e.g., ethnic bias in judicial tools). It may foster passivity or "artificial" hearts.
Lethal Autonomous Weapons (LAWS): "Autonomous weapon systems can never be morally responsible subjects"; human oversight is imperative to comply with humanitarian law. Pope Francis decried their potential for detached warfare and arms proliferation.
Domination Over Life: Echoing Dignitas Personae, techniques dominating human origins (e.g., AI in reproduction) violate dignity. In childhood/adolescence, AI poses risks to minors' data privacy.
Social Inequities: AI could exacerbate divides between nations/classes, favoring "throwaway culture" over encounter. Energy demands threaten the common home.
Pope Leo XIV warns of interacting with machines "as if they were interlocutors," eroding recognition of the truly human.
When human-centered, AI promotes "integral human development": agriculture, education, healthcare, evangelization. Pope Francis urged AI for poverty alleviation, cultural preservation, and eco-sustainability. Pope Leo XIV calls for AI serving the Church's mission—e.g., Catholic education, compassionate care—fostering "justice, solidarity, and reverence for life."
Key imperatives:
Antiqua et Nova prioritizes dignity and fraternity as "indisputable criteria."
While unanimous on principles, sources note evolving challenges: quantum computing may obscure algorithms further; AI in communications risks ideological sway. No black-and-white on all applications (e.g., homologous techniques "less reprehensible" but unacceptable), but higher authority (papal addresses, Dicastery notes) prevails, with recency favoring 2024-2025 documents amid rapid AI advances.
COMECE welcomes regulatory efforts but stresses ethical foundations beyond efficiency.
Catholic teaching demands emerging technologies exalt—not eclipse—human dignity, fraternity, and the common good. By subordinating AI to moral discernment, the Church envisions tools for peace, justice, and creation care, urging "algor-ethics," oversight, and inclusive dialogue. As Pope Leo XIV affirms, intelligence finds meaning in "love, freedom, and relationship with God."
