Notwithstanding the regeneration of papal Catholicism since the middle of the sixteenth century, Hildebrand’s politico-theocratic ideal was not realized. Even Catholic princes would not be dictated to on political matters by the vicar of Christ. The most powerful of them, France, Austria, and Spain, during the sixteenth century, and subsequently also Portugal, had succeeded in the claim to the right of excluding objectionable candidates in papal elections. Ban and interdict had lost their power. The popes, however, still clung to the idea after they had been obliged to surrender the reality, and issued from time to time powerless protestations against disagreeable facts of history. Several new monkish orders were instituted during this century, mostly for teaching the young and tending the sick, but some also expressly for the promoting of theological science. Of all the orders, new and old, the Jesuits were by far the most powerful. They were regarded with jealousy and suspicion by the other orders. In respect of doctrine the Dominicans were as far removed from them as possible within the limits of the Tridentine Creed. But notwithstanding any such mutual jealousies, they were all animated by one yearning desire to oppose, restrict, and, where that was possible, to uproot Protestantism. With similar zeal they devoted themselves with wonderful success to the work of foreign missions. § 156.1. =The Papacy.=--=Paul V.=, A.D. 1605-1621, equally energetic in his civil and in his ecclesiastical policy, in a struggle with Venice, was obliged to behold the powerlessness of the papal interdict. His successor, =Gregory XV.=, A.D. 1621-1623, founded the Propaganda, prescribed a secret scrutiny in papal elections, and canonized Loyola, Xavier, and Neri. He enriched the Vatican Library by the addition of the valuable treasures of the Heidelberg Library, which Maximilian I. of Bavaria sent him on his conquest of the Palatinate. =Urban VIII.=, A.D. 1623-1644, increased the Propaganda, improved the Roman “Breviary” (§ 56, 2), condemned Jansen’s _Augustinus_ (§ 156, 5), and compelled Galileo to recant. But on the other hand, through his onesided ecclesiastical policy he was led into sacrificing the interests of the imperial house of Austria. Not only did he fail to give support to the emperor, but quite openly hailed Gustavus Adolphus, the saviour of German Protestantism, as the God-sent saviour from the Spanish-Austrian tyranny. For this he was pronounced a heretic at the imperial court, and threatened with a second edition of the sack of Rome (§ 132, 2). At the same time his soul was so filled with fanatical hatred against Protestantism, that in a letter of 1631 he congratulated the Emperor Ferdinand II. on the destruction of Magdeburg as an act most pleasing to heaven and reflecting the highest credit upon Germany, and expressed the hope that the glory of so great
