Pope Leo XIV issued a 42,300-word encyclical, 'Magnifica Humanitas,' on May 25, warning the world about artificial intelligence risks, according to The New York Times and OSV News. The document called for AI to be 'disarmed'. This extensive papal critique positions the Vatican as an urgent voice in global AI ethics, prioritizing human dignity and safety.

While AI development accelerates with promises of progress, Pope Leo XIV's encyclical asserts a critical moral imperative: slow down and ensure human control, especially in warfare and politics.

Pope Leo XIV's 'Magnifica Humanitas' isn't just a moral framework; it's a direct condemnation of AI's current trajectory. It asserts that AI's use in autonomous warfare and political manipulation inherently renders modern conflict unjust and erodes human agency. The encyclical will likely spark significant debate and pressure on policymakers and AI developers to integrate ethical considerations and human oversight into future technological advancements.

The Pope's Specific Warnings on AI

  • Pope Leo condemned the use of AI in warfare, stating that reducing human control of weaponry makes it harder to consider a war 'just', according to BBC.
  • He also decried AI's impact on politics, specifically its use to manipulate images and videos, exposing people to biased or misleading perspectives, according to BBC.

These condemnations reveal a core papal concern: AI's capacity to diminish human agency and moral accountability. The Pope argues that ceding control in these critical domains not only risks destabilizing global security but also fundamentally undermines the ethical foundations of human society. The implication is clear: true progress requires preserving human moral authority, not automating it away.

A Major Teaching Document for the AI Age

The 42,300-word encyclical is the first major teaching document of Pope Leo XIV's papacy. It is not merely a statement but a foundational moral teaching, explicitly warning that artificial intelligence needs to be 'disarmed', according to BBC.
