This was the commencement of the long debate _De Auxiliis_, between Jesuits and Dominicans, which lasted for a century, until both sides were silenced by the Holy See, without either being able to claim the victory. Fray Luis had excited many enmities--though not as many as he was in the habit of claiming--and the occasion was favorable for striking at him and at those whom he supported. Fray Juan de Santa Cruz drew up an account of the discussions, with a censure of the erroneous and heretical propositions defended; it was not a personal denunciation of any one, but he declared that the agitation and disquiet of the schools demanded a settlement by the Inquisition. This he presented, February 5th, at Valladolid, to the inquisitor, Juan de Arrese and, from the marginal notes, it appears that, besides Fray Luis, two Jesuits and a Benedictine were marked for prosecution. In March, Inquisitor Arrese came to Salamanca on a mission to suppress astrology and took the opportunity to gather testimony on the scholastic quarrel. Various witnesses, some of them Augustinians, came forward spontaneously with evidence, and the Mercenarian, Francisco Zumel presented a series of propositions, purporting to be drawn from a lecture by Fray Luis on predestination, of which the worst was that Christ on the cross was destitute of God and was provoked to sin. Zumel was a bitter enemy of Luis, who had defeated him, four years before, in competition for the chair of moral philosophy; both had their partizans and their quarrels were the cause of much trouble.[355] [Sidenote: _LUIS DE LEON_] Fray Luis's experience of the Inquisition naturally led him to seek exculpation. Three times he appeared voluntarily before Arrese and made verbal and written statements, in which he rendered an account of his share in the debates. He admitted that he had defended a position opposite to what he had previously taught, which was not without a certain temerity, as differing from the ordinary language of the schools, and not proper for public debate, as it was delicate, difficult of comprehension and liable to lead the hearers into error. He protested that he had not intended to offend Catholic doctrine and, if he had said anything inconsiderately, he submitted it to the censure and correction of the holy tribunal. He also laid much stress on the notorious hatred of the Dominicans towards him, and the manner in which they lost no opportunity of decrying his doctrine, his person and his morals.[356]
