he upheld the authority of his see, and the unadulterated doctrines of his Church, with all the stubbornness and vehemence of Hildebrand. Gregory the Thirteenth exerted himself not only to imitate but to surpass Pius in the severe virtues of his sacred profession. As was the head, such were the members. The change in the spirit of the Catholic world may be traced in every walk of literature and of art. It will be at once perceived by every person who compares the poem of Tasso with that of Ariosto, or the monuments of Sixtus the Fifth with those of Leo the Tenth. But it was not on moral influence alone that the Catholic Church relied. The civil sword in Spain and Italy was unsparingly employed in her support. The {325}Inquisition was armed with new powers and inspired with a new energy. If Protestantism, or the semblance of Protestantism, showed itself in any quarter, it was instantly met, not by petty, teasing persecution, but by persecution of that sort which bows down and crashes all but a very few select spirits. Whoever was suspected of heresy, whatever his rank, his learning, or his reputation, knew that he must purge himself to the satisfaction of a severe and vigilant tribunal, or die by fire. Heretical books were sought out and destroyed with similar rigour. Works which were once in every house were so effectually suppressed that no copy of them is now to be found in the most extensive libraries. One book in particular, entitled “Of the Benefits of the Death of Christ,” had this fate. It was written in Tuscan, was many times reprinted, and was eagerly read in every part of Italy. But the inquisitors detected in it the Lutheran doctrine of justification by faith alone. They proscribed it; and it is now as hopelessly lost as the second decade of Livy.
