Pope Leo Abolishes 'Just War' Theory in Historic Declaration

Pope Leo has repudiated the centuries-old 'just war' theory, which has been used by the Catholic Church to evaluate the justification for war, in his first major document. This move shifts the Church's stance towards peace diplomacy, marking a significant moment with implications for global powers.

Pope Leo has issued a landmark encyclical that repudiates the Catholic Church's centuries-old 'just war' theory. This doctrine has historically been used to evaluate the justification for waging wars. Experts believe this stance could have profound implications for global powers and international diplomacy.

The encyclical, titled "Magnifica Humanitas," argues that humanity now possesses more effective and constructive means, such as dialogue and diplomacy, to promote peace and resolve conflicts. This document also contains a clear apology for the Church's historical role in supporting transatlantic slavery.

Chicago Cardinal Blase Cupich emphasized that the 'just war' theory was meant to restrain, not justify, warfare. Pope Leo's call for moving beyond this outdated theory comes amid criticisms of how it has been used by global leaders, including to justify the Iran war. Leo highlights the influence of the arms industry in perpetuating conflicts, urging a shift towards nonviolent strategies.
