Carranza had made enemies of several bishops, when he published his treatise _On the Residence of Bishops_: the reputation which he acquired for learning in the Council of Trent, at the expense of several individuals who considered themselves superior to him, rendered them also his enemies, or at least his rivals. Of this number were Melchior Cano, who has been already mentioned; their rivalry was changed into open jealousy on his part, and on that of Fray Juan de Regla, when Carranza was appointed Archbishop of Toledo. This hatred became common to others, when, after refusing the archbishopric, Fray Bartholomew recommended the three persons before mentioned to the king: among them were Don Ferdinand Valdes, inquisitor-general; Don Pedro de Castro, Bishop of Cuença, a son of the Count de Lemos; and a man of much greater merit, Don Antonio Augustine, Archbishop of Tarragona, who was the luminary of Spain in sacred literature. These persons endeavoured to conceal their sentiments, but their words and actions betrayed them. Besides this principal motive for the conspiracy against the archbishop, we may be permitted to suppose another. Carranza had given a copy of his Catechism to the Marchioness d'Alcañices in several detached pieces; when it was printed, he distributed it as it came from the press. The Marchioness d'Alcañices intrusted the work to several pupils or partisans of the archbishop, among whom were Fray Juan de la Peña, Fray Francis de Tordesillas, and Fray Louis de la Cruz; it was also read by Melchior Cano, who, in different conversations, plainly insinuated that it contained propositions tending to the Lutheran heresy. Don Ferdinand Valdés being informed of these circumstances, bought several copies of the Catechism, and sent them to persons with whose opinions he was well acquainted, desiring them to read it attentively, and to observe all that merited theological censure, but not to give their opinions in writing until they had again communicated with him. The persons he selected, were Fray Melchior Cano, Fray Dominic Soto, Fray Dominic Cuevas, the Master Carlos, and Fray Pedro Ibarra, provincial of the Franciscans.
