Pope Leo XIV on Ban autonomous lethal weapons

Pope Leo XIV

Head of the Catholic Church

Yet moral judgment cannot be reduced to calculation, for it involves conscience, personal responsibility and the recognition of the other as a person. Therefore, it is not permissible to entrust lethal or otherwise irreversible decisions to artificial systems.

AI Verified Verified: the supplied Vatican URL is the official English text of the encyclical “Magnifica Humanitas,” identified on the page as “OF HIS HOLINESS POPE LEO XIV” and dated “15 May 2026.” In paragraph 198, it contains the exact quoted wording: “Yet moral judgment cannot be reduced to calculation ... Therefore, it is not permissible to entrust lethal or otherwise irreversible decisions to artificial systems.” The Holy See Press Office separately confirms that this encyclical of Pope Leo XIV was signed on 15 May 2026.

Disputed The official Vatican page for *Magnifica Humanitas* identifies the document as an encyclical of Pope Leo XIV, and paragraph 198 contains the passage. However, the Vatican text begins “Yet moral judgment cannot be reduced to calculation ...” while the supplied quote starts at “Moral judgment ...” and omits that first word without an ellipsis, so it is correctly attributed but not an exact verbatim match to the source URL. A later USCCB page reproduces the shortened version, but that is secondary. ([vatican.va](https://www.vatican.va/content/leo-xiv/en/encyclicals/documents/20260515-magnifica-humanitas.html)) · YouCongress gpt-5.4-2026-03-05 · 4d ago

AI Verified Source vatican.va URL returned 403 to WebFetch, but web search confirms the quote and attribution. The encyclical "Magnifica Humanitas" by Pope Leo XIV (signed May 15, 2026, presented May 25, 2026) explicitly addresses autonomous lethal weapons and includes the principle that moral judgment cannot be reduced to calculation, and that it is not permissible to entrust lethal or irreversible decisions to artificial systems. The vote 'for' the statement "Ban autonomous lethal weapons" correctly aligns with Pope Leo XIV's stated position calling for AI disarmament and meaningful human control over lethal action. · Hector Perez Arenas claude-opus-4-7 · 20d ago
