13. =The Jesuits.=--The main instruments of the Popes to win back those who had broken loose from their authority were the members of the Society of Jesus, usually known as Jesuits. The society was founded in =1540= by Ignatius Loyola, a Spanish knight who, having been incapacitated by a wound for a military career, had devoted himself to the chivalry of religion. The members of the society which he instituted were not, like the monks, to devote themselves to setting an example of ascetic self-denial, nor, like the friars, to combine asceticism with preaching or well-doing. Each Jesuit was to give himself up to winning souls to the Church, whether from heathenism or from heresy. With this end, the old soldier who established the society placed it under more than military discipline. The first virtue of the Jesuit was obedience. He was to be in the hands of his superior as a stick in the hand of a man. He was to do as he was bidden, unless he was convinced that he was bidden to commit sin. What was hardest, perhaps, of all was that he was not allowed to judge his own character in choosing his work. He might think that he was admirably qualified to be a missionary in China, but if his superior ordered him to teach boys in a school, a schoolmaster he must become. He might believe himself to be a great scholar and fitted by nature to impart his knowledge to the young, but if his superior ordered him to go as a missionary to China, to China he must go. Discipline voluntarily accepted is a great power in the world, and this power the Jesuits possessed.
