The final period of Loyola’s life was spent in Rome or its vicinity. In 1539 the companions decided to form a permanent union, adding a vow of obedience to a superior elected by themselves to the vows of poverty, chastity, and obedience to the Roman pontiff that they had already taken. In 1540 Pope Paul III approved the plan of the new order. Loyola was the choice of his companions for the office of general.
