Realising that his defective education was a serious obstacle to the establishment of the religious order that he contemplated, he went to work with a will to acquire the rudiments of grammar. When this had been accomplished successfully he pursued his higher studies at Alcala, Salamanca, and Paris, where he graduated as a doctor in 1534. But while earnest in the pursuit of knowledge he never forgot that knowledge was but a means of preparing himself for the accomplishment of the mission to which God had called him. While at Paris he gathered around him a group of students, Francis Xavier, Lainez, Salmeron, Bodadilla, Rodriguez and Faber, with which body Lejay, Codure and Broet were associated at a later period. On the feast of the Assumption (1534) Ignatius and his companions wended their way to the summit of Montmartre overlooking the city of Paris, where having received Holy Communion they pledged themselves to labour in the Holy Land. Having discovered that this project was almost impossible they determined to place themselves at the disposal of the Pope. In Rome Ignatius explained the objects and rules of the proposed society to Paul III. and his advisers. In September 1540 the approval of the Pope was obtained though with certain restrictions, which were abolished in 1543, and in the following year Ignatius was elected first general of the Society of Jesus. St. Ignatius had the greatest respect for the older religious orders, the Benedictines, the Dominicans, and the Franciscans, to all of which he was deeply indebted; but he believed that the new conditions under which his followers would be called upon to do battle for Christ necessitated new rules and a new constitution. The Society of Jesus was not to be a contemplative order seeking only the salvation of its own members. Its energies were not to be confined to any particular channel. No extraordinary fasts or austerities were imposed, nor was the solemn chanting of the office or the use of a particular dress insisted upon. The society was to work "for the greater glory of God" in whatever way the circumstances demanded. On one thing only did St. Ignatius lay peculiar emphasis, and that was the absolute necessity of obedience to superiors in all things lawful, and above all of obedience to the Pope. The wisdom of this injunction is evident enough at all times, but particularly in an age when religious authority, even that of the successor of St. Peter, was being called in question by so many. Members of the society were forbidden to seek or accept any ecclesiastical dignities or preferments.
