VATICAN CITY (AP) — Pope Leo XIV laid out the vision of his papacy Saturday, identifying artificial intelligence as one of the most critical matters facing humanity.

In his first formal audience, Leo made clear he will follow in the modernizing reforms of his predecessor, Pope Francis, to make the Catholic Church inclusive, attentive to the faithful and a church that looks out for the “least and rejected.”

Citing Francis repeatedly, he told the cardinals who elected him that he was fully committed to the reforms of the Second Vatican Council, the 1960s meetings that modernized the church. He identified AI as one of the main issues facing humanity, saying it poses challenges to defending human dignity, justice and labor.

Leo referred to AI in explaining the choice of his name: His namesake, Pope Leo XIII, was pope from 1878 to 1903 and laid the foundation for modern Catholic social thought. He did so most famously with his 1891 encyclical Rerum Novarum, which addressed workers’ rights and capitalism at the dawn of the industrial age. The late pope criticized both laissez-faire capitalism and state-centric socialism, giving shape to a distinctly Catholic vein of economic teaching.

In his remarks Saturday, Leo said he identified with his predecessor, who addressed the great social question of the day posed by the industrial revolution in the encyclical.

“In our own day, the church offers everyone the treasury of its social teaching in response to another industrial revolution and to developments in the field of artificial intelligence that pose new challenges for the defence of human dignity, justice and labour,” he said.

Toward the end of his pontificate, Francis became increasingly vocal about the threats to humanity posed by AI and called for an international treaty to regulate it.

He warned that such powerful technology risks turning human relations into mere algorithms. Francis brought his message to the Group of Seven industrialized nations when he addressed their summit last year, insisting AI must remain human-centric so that decisions about when to use weapons or even less-lethal tools always remain made by humans and not machines.

The late Argentine pope also used his 2024 annual peace message to call for an international treaty to ensure AI is developed and used ethically, arguing that a technology lacking human values of compassion, mercy, morality and forgiveness is too perilous to develop unchecked.
