The intervention of the nuncio shows that the struggle had widened far beyond the theological question as to the lawfulness of interrogating demons and the guilt of the luckless Froilan Díaz. Two important principles had become involved--the appellate jurisdiction of Rome and its original jurisdiction in determining disputed points in the internal organization of the Spanish Inquisition. Pope Clement had eagerly welcomed the opening afforded by Mendoza, not only to claim that Froilan's case should be submitted to him, but he had also assumed, in Mendoza's favor, that the Suprema was subordinate to the inquisitor-general, through whom its powers were derived from the Holy See, which alone could decide the question. All this was vigorously combated by Cardona, with the aid of the Council of Castile. In the name of the Suprema, which now had three new members, he rehearsed all of Ferdinand's decrees against appeals and argued that the Suprema had always been a royal council, subjected to the king, and that the only distinction between its members and the inquisitor-general lay in his prerogatives as to appointments. He earnestly supplicated the king to order the seizure of a letter of Cardinal Paolucci, papal secretary of state, committing Froilan's case to Mendoza or to the Archbishop of Seville. The nuncio, on the other hand, insisted that the papacy had never divested itself of its supreme authority to judge everything throughout the world, and that the pope was the only authority entitled to construe papal grants, including the functions of the Suprema. While the controversy thus raged, Froilan lay forgotten in his dungeon.
