Loyola had been a military man. He believed in discipline, and absolute obedience to the orders of the superior dignitaries became one of the main causes for the enormous success of the Jesuits. They specialised in education. They gave their teachers a most thorough-going education before they allowed them to talk to a single pupil. They lived with their students and they entered into their games. They watched them with tender care. And as a result they raised a new generation of faithful Catholics who took their religious duties as seriously as the people of the early Middle Ages.
