In scrapping the Vatican's 'just war' theory, Pope Leo could change history

Theory Briefing

  • Just War theory, over 1,000 years old, has long given the Catholic Church a framework to deem some military violence morally legitimate.
  • Pope Leo scrapping the doctrine would mark one of the most significant reversals in Church moral teaching in modern history.
  • The move forces a question philosophy has never fully settled: can violence ever be truly justified, or is that always a rationalization?
  • Removing the Church's moral cover for war could shift how billions of Catholics — and the institutions they influence — think about armed conflict.
