And not less remarkable than these missionaries were those who labored in other spheres. Loyola himself, though visionary and monastic, had no higher wish than to infuse piety into the Catholic Church, and to strengthen the hands of him whom he regarded as God's vicegerent. Somehow or other he succeeded in securing the absolute veneration of his companions, so much so that the sainted Xavier always wrote to him on his knees. His "Spiritual Exercises" has ever remained the great text-book of the Jesuits,--a compend of fasts and penances, of visions and of ecstasies; rivalling Saint Theresa herself in the rhapsodies of a visionary piety, showing the chivalric and romantic ardor of a Spanish nobleman directed into the channel of devotion to an invisible Lord. See this wounded soldier at the siege of Pampeluna, going through all the experiences of a Syriac monk in his Manresan cave, and then turning his steps to Paris to acquire a university education; associating only with the pious and the learned, drawing to him such gifted men as Faber and Xavier, Salmeron and Lainez, Borgia and Bobadilla, and inspiring them with his ideas and his fervor; living afterwards, at Venice, with Caraffa (the future Paul IV.) in the closest intimacy, preaching at Vicenza, and forming a new monastic code, as full of genius and originality as it was of practical wisdom, which became the foundation of a system of government never surpassed in the power of its mechanism to bind the minds and wills of men. Loyola was a most extraordinary man in the practical turn he gave to religious rhapsodies; creating a legislation for his Society which made it the most potent religious organization in the world. All his companions were remarkable likewise for different traits and excellences, which yet were made to combine in sustaining the unity of this moral mechanism. Lainez had even a more comprehensive mind than Loyola. It was he who matured the Jesuit Constitution, and afterwards controlled the Council of Trent,--a convocation which settled the creed of the Catholic Church, especially in regard to justification, and which admitted the merits of Christ, but attributed justification to good works in a different sense from that understood and taught by Luther.
