Yet even before the council actually reopened, i.e., May 1, 1551, it had become evident that the papal view of its purposes remained as widely divergent from the Imperial as in the days of Paul III. The nomination of Cardinal Crescentio, a Roman by birth, as president of the council, with two Italian prelates, Pighino of Siponto and Lippomano of Verona, by his side, was in itself ominous; and the German Protestants, upon whom the Emperor pressed safe-conducts at Augsburg (1551), perceived the papal intention of treating the council as a mere continuation of that which had previously sat at Trent. Still, several of them, as well as the Catholic electors, finally promised to attend. On the other hand, Henry II of France prohibited the appearance of a single French prelate, and began to talk of a Gallican council. Thus the brief series of sessions held at Trent from May, 1551, to April, 1552, proved in the main, though not altogether, barren of results. Unless the assembled fathers were prepared to reconsider the decrees already passed, and to force the assent of the Pope to a religious policy of quite unprecedented breadth, another deadlock was at hand; and already, in the early months of 1552, the council, this time with the manifest connivance of Rome, began to thin. When, in April, Maurice of Saxony, now the ally of France, approached the southern frontier of the Empire, the Pope, whose own French war had taken a disastrous turn, had reason enough for shunning further coöperation with the Emperor. The council dwindled apace in spite of the efforts of Charles V, who had never ceased to believe in his schemes. Finally, however, he could not prevent the remnants of the council from passing a decree suspending its sessions for two years, which was opposed by not more than a dozen loyal Spanish votes, April 28, 1552.

Charles V's resignation of his thrones (1554-1556) resulted, though far from being so intended, in a confession of his failure. While it was in progress, Julius III died (March 23, 1555), leaving behind him scant evidence to support the rumor of his having indulged, at all events in the last period of his reign, in ideas of church reformation. But the choice of his successor, Marcellus II (April-May, 1555), shows that these ideas were not yet extinct in the sacred college, notwithstanding the simultaneous creation by Julius III of fourteen cardinals; for Cervino had always been reckoned a member, though a moderate one, of the reforming party. Far greater, however, was the significance attaching to the election of the Pope who speedily took the place of Marcellus.

The pontificate of Paul IV (Gian Pietro Caraffa, May, 1555-August, 1559) forms one of the most remarkable chapters in the history of the Counter-reformation, which in him seemed under both its aspects to have secured the mastery of the Church. God's will alone, he was convinced, had placed him where he stood; for he was unconscious of having achieved anything through the favor of man. He was now seventy-nine years of age, but he had never been more eager to devote himself to his chosen purpose—the establishment in the eyes of all peoples of a pure and spiritually active church, free from all impediments of corruptions and abuses, and purged of all poison of heresy and schism.

Fully aware—though he had belonged to it himself—of the virtual failure of Paul III's commission of reform, Paul IV, in his first bull, solemnly promised an effectual reform of the Church and the Roman Curia, and lost no time in instituting a congregation for the purpose. The commission, which consisted of three divisions, each of them composed jointly of cardinals, bishops, and doctors, wisely addressed itself in the first instance to the question of ecclesiastical appointments. The new Pope likewise issued orders for the specific reform of monastic establishments, and his energy seemed to stand in striking contrast with the hesitations and delays of the recently suspended council.

But once more the seductions of the temporal power overcame its holder. Caraffa's residence in Spain, and enthusiasm for the religious ideals and methods prevalent there, had not eradicated the bitterly anti-Spanish feeling inborn in him as a Neapolitan, and Charles V, returning hatred for hatred, had done his utmost to offend the dignity and damage the interests of the Cardinal. To these personal and national sentiments had been added the conviction that the Emperor's dealings with the German Protestants had encouraged them to deal a deadly blow to the unity and strength of the Church; and thus Paul IV allowed himself to be borne away by passion. His fiery temperament, fretted rather than soothed by old age, left him and those around him no peace; he maltreated the imperialist cardinals and the dependents of the Emperor within his reach, and sought to instigate the French government to take up arms once more.

Of a sudden, as if in another gust of passion, he made a clean sweep of the obstacles which his own perversity had placed in his path, and then took up in terrible earnest the work of church reform. He would allow no appointment savoring of corruption to any spiritual office; he would hear of no exception to the duty of residence; he completely abolished dispensations for marriages within prohibited degrees. Into the general management of the churches of the city, as well as into that of his own papal court, he introduced so strict a discipline that Rome was likened to a well-conducted monastery. But the agency which above all others he encouraged was that which his own advice had established in the centre of the Catholic world—the Inquisition. From the sacred college downward, no sphere of life was exempted from its control; and his intolerance extended itself to the very Jews whose privileges in the papal states he ruthlessly revoked. On his death-bed he recommended the Inquisition with the holy see itself to the pious cardinals surrounding him. It was afterward observed that many reforms decreed in its third period by the Council of Trent were copied from the ordinances issued by Paul IV in this memorable biennium. But inasmuch as during his pontificate the Church of Rome had lost ground in almost every country of Europe except Italy and Spain, his death (August 18, 1559) naturally brought with it a widespread renewal of the demand for remedies more effective than those supplied by his feverish activity and by the operations of his favorite institution.

Personally, Pius IV (1559-1566) was regarded, and probably chosen, as an opponent of the late Pope; his family history inclined him to the Imperial interest, and he was understood to favor concessions to Germany with a view of bringing her stray sheep back into the fold. But in general he furthered rather than arrested the religious reaction. Above all, the Inquisition, though he is not known to have done anything to intensify its rigor or augment its authority, went on as before. Carlo Borromeo,[56] the nephew of Pius IV, served the holy see in a spirit of unselfish devotion, and began those efforts on behalf of religion which in the end obtained for him a place among the saints of the Church—a position not reached by many popes' nephews. With the aid of this influence, Pius IV came to perceive that the future, both of the Church and of the papacy, depended on the spirit of confidence and cohesion which could be infused into the former; nor had he from the very outset of his pontificate ever doubted the expediency of reassembling the council at Trent.

The emperor Ferdinand and the French Government, who persisted in treating the reunion of the Church as the primary object of the council, at first strongly urged the substitution for Trent of a genuinely German or French town, where the German bishops, and perhaps even the Protestants, would feel no scruple about attending. But a totally free and new council of this description lay outside the horizon of the papacy; and Pius IV might have let fall the plan altogether but for the fear of the entire separation in that event of the Gallican Church from Rome. In France, Protestantism had made considerable strides during the reign of Henry II (1547-1559). About six weeks before the death of Henry the first national synod of Protestants was held at Paris (May, 1559). Under Francis II the Guise influence became paramount, and the persecution of the Protestants continued. But though the suppression, just before this, of the so-called conspiracy of Amboise had temporarily added to the power of the Guises, it had also made the Queen-mother, Catherine de' Medici, resolve not to let the power of the state pass wholly out of her hands. Hence the appointment of the large-hearted L'Hôpital as chancellor, and the assembly of notables at Fontainebleau (August), where the grievances against Rome found full expression, and where arrangements were made for a meeting of the States-general and a national council of the French Church. This resolution determined Pius IV to lose no further time. On November 29, 1560, he issued a bull summoning all the prelates and princes of Christendom to Trent for the following Easter. The invitation included both Eastern schismatics and Western heretics, Elizabeth of England among the rest; but neither she nor the German Protestant princes assembled at Naumburg, nor the kings of the Scandinavian North, would so much as receive the papal summons. In France the death of Francis II (December 5, 1560) further depressed the Guise influence; and Catherine entered into negotiations with the Pope with a view to concessions such as would satisfy the Huguenots while approved by the French bishops. The "Edict of January" (1562), which followed, long remained a sort of standard of fair concessions to the Huguenots.

The first deliberations of the reassembled council were barren. The question which really came home to the fathers of the Church assembled at Trent presented itself again when the sacrament of orders had in due course to be debated. The imperial and French ambassadors still coöperated as actively as ever, and the episcopal party, the Spanish prelates in particular, entered upon the struggle with a full sense of its critical importance. If the right divine of episcopacy could be declared, with it would be established the divine obligation of residence. Pius IV accordingly showed considerable shrewdness in instructing the legates at once to formulate a decree on residence, which, while leaving the question of divine obligation open, imposed penalties on nonresidence—except for lawful reasons—sufficient to meet practical requirements. But though such a decree was passed by the council, the debates on the origin of the episcopal office, which involved nothing less than the origin and nature of the papal supremacy, continued (November); and the critical nature of the discussion was the more apparent when in the midst of it there at last arrived nearly a score of French bishops, headed by the Cardinal of Lorraine. Hitherto France had been represented at the council by spokesmen of the French court and of the Parliament of Paris; now the foremost among the prelates of the monarchy, whose abilities, however, unfortunately fell far short of his pretensions, announced in full conciliar assembly the demands of his branch of the Church. The recent January edict proved the strength of the Huguenots in France; and though the Cardinal's first speech at Trent breathed nothing but condemnation of these heretics, it suited him to pose as the advocate of as extensive a series of reforms as had yet been urged upon the council.

Further additions were made in the "libel," which was shortly afterward (January, 1563) presented by the French ambassador, and perfect harmony existed between the French and the imperial policy at the council. What decision, then, was to be expected on the crucial question as to the relations between papal and episcopal authority? How could a recognition of the Pope's claim to be regarded as rector universalis ecclesiæ be expected from such a union of the ultramontane forces? The current was not likely to be stopped by the papal court, which about this time Pius IV announced on his own account at Rome; it seemed on the point of rising higher than ever when (February, 1563) the Cardinal of Lorraine and some other prelates waited upon the Emperor at Innsbruck. In truth, however, a turning-point in the history of the council was close at hand. The Cardinal of Lorraine had left Trent for Innsbruck with threats of a Gallican synod on his lips. Ferdinand I had arrived there very wroth with the council, and had received the Bishop of Zante (Commendone), whom the legates sent to deprecate his vexation, with marked coolness. The remedies proposed to the Emperor by the Cardinal were drastic enough; the council was to be swamped by French, German, and Spanish bishops, and the Emperor, by repairing to Trent in person, was to awe the assembly into discussing the desired reforms, whether with or without the approval of the legates. But Ferdinand I, by nature moderate in action, and taught by the example of his brother, Charles V, the danger of violent courses, preferred to resort to a series of direct and by no means tame appeals to the Pope. The latter, indisposed as he was to support a fresh proposition for the removal of the council to some German town, urged by France, but resisted by Spain, which at the same time persistently opposed the concession of the cup demanded by both France and the Emperor, saw his opportunity for taking his adversaries singly. The deaths about this time (March, 1563) of the presiding legate, Cardinal Gonzaga, and of his colleague Cardinal Seripando, both of whom had occasionally shown themselves inclined to yield to the reforming party, were likewise in his favor. Their places were filled by Cardinals Morone, formerly a prisoner indicted by the Inquisition, now an eager champion of papal claims, and Navagero, a Venetian by birth, but not in his political sentiments. Morone, though he had left Rome almost despairing of any favorable issue of the council, at once began to negotiate with the Emperor through the Jesuit Canisius. The leverage employed may, in addition to the distrust between Ferdinand and his Spanish nephew, and the ancient jealousy between Austria and France, have included some reference to the heterodox opinions and the consequently doubtful prospects of the Emperor's eldest son, Maximilian.
