Pope Leo XIV will release his first encyclical Monday, titled Magnifica Humanitas, focusing on AI risks and social disruption, echoing Leo XIII's 1891 Rerum Novarum. He will appear at a news conference, underscoring a shift from sexual morality to broader justice issues, a move that could reshape Catholic social teaching and affect its influence worldwide.

The document arrives as conservatives in the US church grapple with waning relevance after culture‑war battles over abortion and gay marriage lost steam. By linking AI‑driven disinformation to human dignity, Leo aims to rally businesses and policymakers toward ethical tech standards, a stance that could pressure tech firms to adopt stricter governance, including major platforms such as Meta and Google today.

Critics note Leo’s emphasis on justice revives a 16th‑century tradition that prioritized economic fairness over sexual sin, a narrative that may restore the church’s voice on labor and immigration. The encyclical’s release coincides with heightened regulatory scrutiny of AI, suggesting the Vatican could become an unexpected stakeholder in forthcoming policy debates in Europe and North America.
