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 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 crushes 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 rigor. 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.
Thus, while the Protestant reformation proceeded rapidly at one extremity of Europe, the Catholic revival went on as rapidly at the other. About half a century after the great separation, there were throughout the North Protestant governments and Protestant nations. In the South were governments and nations actuated by the most intense zeal for the ancient church. Between these two hostile regions lay, morally as well as geographically, a great debatable land. In France, Belgium, Southern Germany, Hungary, and Poland, the contest was still undecided. The governments of those countries had not renounced their connection with Rome; but the Protestants were numerous, powerful, bold, and active. In France, they formed a commonwealth within the realm, held fortresses, were able to bring great armies into the field, and had treated with their sovereign on terms of equality. In Poland, the King was still a Catholic; but the Protestants had the upper hand in the Diet, filled the chief offices in the administration, and, in the large towns, took possession of the parish churches. "It appeared," says the papal nuncio, "that in Poland, Protestantism would completely supersede Catholicism." In Bavaria, the state of things was nearly the same. The Protestants had a majority in the Assembly of the States, and demanded from the duke concessions in favor of their religion, as the price of their subsidies. In Transylvania, the House of Austria was unable to prevent the Diet from confiscating, by one sweeping decree, the estates of the Church. In Austria proper it was generally said that only one thirtieth part of the population could be counted on as good Catholics. In Belgium the adherents of the new opinions were reckoned by hundreds of thousands.
