Fratelli Tutti §25
Fratelli Tutti: On Fraternity and Social Friendship
25 War, terrorist attacks, racial or religious persecution, and many other affronts to human dignity are judged differently, depending on how convenient it proves for certain, primarily economic, interests. What is true as long as it is convenient for someone in power stops being true once it becomes inconvenient. These situations of violence, sad to say, “have become so common as to constitute a real ‘third world war’ fought piecemeal”.
