Spurning just war, Pope Leo ends Catholic 'permission slip' for conflicts

AI Summary

Pope Leo has renounced the Catholic Church's long-standing just war doctrine, challenging centuries of Church teachings on the justification of war. The pope's document also calls for global AI regulation and offers a historic apology for the Church's support of transatlantic slavery.

By Joshua McElwee VATICAN CITY, May 28 (Reuters) - Pope Leo this week repudiated a major teaching used by the Catholic Church since at least the fifth century to evaluate when countries might be justified in waging wars, in a move experts said could have long-reaching impact for global powers. The disavowal of the doctrine came in the pope's first major document, issued on Monday, which also urged global regulation of AI systems and made the clearest apology yet for the Catholic Church's historic role in supporting transatlantic slavery.
