The one who planned this visit to Spain was the plotter Mendoza. His purpose was simply to humiliate the General by confronting him with the king, the greatest nobles of the realm and the Inquisition, and then to force from him all sorts of permissions which were in direct violation of the methods of Jesuit life. The story, as it appears in Astrain, is simply amazing. Mendoza had actually procured from the Pope, through the magnates of Spain, permission to receive and spend money as he wished, to be free from all superiors, and to go and live wherever he chose. When Aquaviva protested to the Pope that such permissions were subversive of all religious discipline, His Holiness suggested a way out of the difficulty, which took every one by surprise--Mendoza was made Bishop of Cuzco in Peru. This interference of rich and powerful outsiders in the family life of the Society, as well as the shameful way in which some of the members sought the favor of men of great influence in the State may explain how, after the angry fulminations of the congregation against the Spanish plotters, it took several years to get even a few of them out of the Society. The dispute, known as the "De Auxiliis," which raged with great theological fury for many years, had for its object the reconciliation of Divine grace with human freedom. "The Dominicans maintained that the difficulty was solved by their theory of physical premotion and predetermination, whereas the Jesuits found the explanation of it in the _Scientia media_ whereby God knows in the objective reality of things what a man would do in any circumstances in which he might be placed. The Dominicans declared that this was conceding too much to free will, and that it tended towards Pelagianism, while the Jesuits complained that the Dominicans did not sufficiently safeguard human liberty and hence seemed to lean towards the doctrines of Calvin" (Astrain). It was not until 1588, that Luis de Molina, whose name is chiefly connected with the doctrine of the _Scientia media_, got into the fight. Domingo Ibánez, the Dominican professor at Salamanca, was his chief antagonist. The debates continued for five years, and by that time there were public disturbances in several Spanish cities. Clement VIII then took the matter in his own hands, and forbade any further discussion till the Holy See had decided one way or the other. The opinions of universities and theologians were asked for, but by 1602 no conclusion had been arrived at, and between that year and 1605, sixty-eight sessions had been held with no result. Thus it went on till 1607, when the Pope decided that both parties might hold their own opinions, but that each should refrain from censuring the other. In 1611, by order of the Pope, the Inquisition issued a decree forbidding the publication of any book concerning efficacious grace until further action by the Holy See. The prohibition remained in force during the greater part of the seventeenth century.
