On September 10, Pope Francis delivered an address to the Pontifical Academy of Sciences. Established in 1936, it is an advisory body whose members include non-Catholics.

During his address, the Pope warned that “unfortunately, history shows signs of regression. Not only are anachronistic conflicts intensifying, but instances of a myopic, extremist, resentful and aggressive nationalism are re-emerging.”

“The many ongoing armed conflicts are of serious concern,” he continued. “I have said that it was a third world war being fought ‘piecemeal’ – perhaps we can now say that it is ‘all out’ – putting people and the planet at ever greater risk.”
