[Sidenote: _ARCHBISHOP CARRANZA_] Pius IV had carried to an extreme his subservience to Philip. Pedro de Avila, one of Philip's agents, wrote, August 23, 1565, that Cardinal Borromeo assured him that the pope had done and was doing more than he had power to do in order to gratify the king; he had gone against the canons, the councils and the cardinals and, when recently he thought himself to be dying, nothing weighed on his conscience more heavily than this.[213] His successor was a man of different stamp. To few popes does Catholicism owe more than to St. Pius V, for, while pitiless in his persecution of heresy, his recognition of the need of reform and his unbending resolution to effect it, regained for the Church much of the respect which it had forfeited. The Spanish agents speedily found that in the matter of Carranza he was incorruptible and intractable. As the ambassador Zuñiga plaintively reported to Philip, February 23, 1566, "He is certainly well-intentioned but, having no experience in affairs of state and no private interests, which are the two things that ordinarily make popes yielding, he fixes his eyes on what he deems just and is immovable."[214] As cardinal-inquisitor and Dominican he had been favorably inclined to Carranza, whose friends received with hope the news of his accession. They conveyed this by means of an arrow aimed at one of his window-shutters and he responded by casting out a paper, picked up by a person stationed for the purpose, in which he addressed the new pope in the words of Peter, "Lord, if it be thou, bid me come unto thee on the water" (Matt. xiv, 28).[215] Pius did not need urging. One of his first acts was to despatch a messenger to Buoncompagni ordering him to remain and bring the affair to a conclusion, but the legate's Spanish experience did not incline him to return from Avignon. Doubtless his report brought conviction that justice was not to be expected in Spain, for Pius speedily made a demand for the person of Carranza and the papers so that he might decide the case. Accustomed to browbeat popes, Philip replied that the demand was offensive and contrary to the royal prerogative, as an attempt to change a matter unalterably fixed by the Holy See, and that it would not be entertained; the pope could commit the case to such persons as he pleased, provided they were Spaniards, otherwise, if Carranza should linger in prison until he died, the responsibility would not be with those who had offered every possible alternative. This audacious answer only strengthened the determination of Pius, who summoned Zuñiga and told him to tell his master that he exposed himself to all the indignation of the Holy See, for the pope was resolved to carry the matter to a conclusion. Zuñiga was silenced and could only report to Philip the terrible earnestness of Pius, from which there was no hope of diverting him.[216]
