Mathematicians Can Be ‘Signs of Hope’ in a Changing World: Pope Leo XIV on International Day of Mathematics

March 2026 : On the occasion of the International Day of Mathematics, Pope Leo XIV called on mathematicians around the world to reflect on the vital role their discipline can play in addressing the challenges facing humanity today. In a message released on Friday, the pontiff encouraged mathematicians to use their knowledge and skills not only for scientific progress but also as a force for hope, ethics, and human development.

The message, conveyed through Cardinal Pietro Parolin, the Vatican’s Secretary of State, was addressed to Turkish mathematician and professor Betül Tanbay, who serves as chair of the International Day of Mathematics initiative. The global observance was marked on March 13 with a series of academic discussions and events.

Tanbay had earlier informed the pope about a special webinar organised under the theme “Mathematics and Hope.” In response, Pope Leo XIV sent a letter extending his greetings and best wishes to all participants involved in the initiative.

In his message, the pontiff invited scholars and researchers to reflect on how mathematics can help humanity navigate the “multiple challenges confronting the human family.” He noted that rapid technological development has brought both opportunities and risks, making it essential for experts to approach scientific advancement with wisdom and responsibility.

According to the pope, mathematicians are uniquely positioned to contribute positively to society. He highlighted the growing importance of mathematical research in areas such as algorithms and artificial intelligence, which are increasingly shaping modern life.

“A particularly fruitful area of research is the use of algorithms, especially in the field of artificial intelligence,” he said, adding that such innovations have immense potential to influence the future.

However, Pope Leo XIV stressed that technological progress must go beyond mere technical expertise. He said that working in such fields requires not only intellectual brilliance but also the integral growth of the human person, including awareness of the ethical and moral dimensions of new technologies.

Drawing from his own experience as a mathematics and physics teacher, the pope reflected on the deeper meaning of education and knowledge. Recalling remarks he made during the Jubilee of the World of Education in October 2025, he said that acquiring vast knowledge alone is not sufficient.

“Possessing vast knowledge is not enough if we don’t know who we are or what the meaning of life is,” he said.

The pope also urged mathematicians and researchers to remain attentive to the spiritual and emotional needs of people in an increasingly digital world. He encouraged them to find ways to humanise the digital sphere, transforming it into a space that promotes fraternity, creativity, and meaningful collaboration.

In this context, Pope Leo XIV called on mathematicians to act as “prophets of hope, truth, and goodness”, using their knowledge to contribute to a more compassionate and responsible society.

The message concluded with the pontiff offering prayers for all those participating in International Day of Mathematics events. He invoked divine blessings of wisdom, joy, and peace upon them and encouraged them to continue their work for the benefit of humanity.

Interestingly, Pope Leo XIV himself has a background in mathematics. Born Robert Francis Prevost, he graduated from Villanova University in Pennsylvania in 1977 with a bachelor’s degree in mathematics, alongside studies in philosophy. Later, while pursuing theological training at the Catholic Theological Union in Chicago, he also taught mathematics part-time at Mendel Catholic High School and occasionally served as a substitute physics teacher at St. Rita of Cascia High School.

His message this year highlights how mathematics, beyond numbers and formulas, can inspire hope and guide humanity in navigating the complexities of a rapidly changing world.
