The Valladolid Inquisitors had not treated him in such fashion as to make him desirous of meeting them again.  This experience was, however, awaiting him.[216] On January 20 or 21, 1582,[217] his former opponent, the Mercenarian Fray Francisco Zumel, took the chair at a theological meeting in Salamanca.  At this meeting a Jesuit named Prudencio de Montemayor put forward a thesis which opened up the difficulties connected with the reconciliation of the theological doctrines of predestination and free-will.  Owing to some disturbance in the assembly, Montemayor’s voice did not reach all who were present and, in the interest of the audience, Luis de Leon repeated Montemayor’s arguments without lending them any support; his action was misunderstood, and many supposed that he was expressing his personal opinions.  In the ensuing discussion his vanquished opponent, Domingo de Guzman, intervened, and with unnecessary acerbity declared that Montemayor’s views were heretical.  Nothing would have been easier than for Luis de Leon to keep out of the fray, especially as he himself held, and had always taught, opinions opposed to those advanced by Montemayor.  If, as Pacheco reports, Luis de Leon was the most taciturn of men, he was chivalrous to the point of quixotism.  In the circumstances silence was impossible for him.  He was for as much liberty of thought as was compatible with orthodoxy; he was persuaded that much of the opposition of the Dominicans to Montemayor was due to the fact that the latter was a Jesuit;[218] and no doubt he was quite human enough to be annoyed at the intrusion of Domingo de Guzman as the champion of doctrinal intolerance....  Be this as it may, Luis de Leon took up the cudgels for Montemayor’s views which, as he maintained, were perfectly tenable.  At a later meeting in Salamanca, Fray Juan de Castaneda, a Benedictine,[219] advanced views very similar to those of Montemayor; Domingo Banez, whose relations with Luis de Leon were never cordial, was even more emphatic than his brother-Dominican, Domingo de Guzman, and denounced Castaneda’s views as savouring of Pelagianism.  A sharp passage of arms followed between Banez and Luis de Leon,[220] and, after some exchange of argument, Banez professed to be satisfied with Castaneda’s thesis, and therefore with Luis de Leon’s explanations.[221] Others were less easily contented; even some of the Augustinian professors at Salamanca were uneasy;[222] and finally the case came before the Inquisition of Valladolid, though the sittings of the court were held in Salamanca.  The delator would appear to have been a Jeromite, Fray Joan de Santa Cruz, who took objection to some sixteen propositions which, as he alleged, were put forward by Luis de Leon.[223] Some exaggeration on the part of Santa Cruz is conceivable.  As a Jeromite, he bore a grudge against Luis de Leon for his overt opposition to the candidature of Hector Pinto at Salamanca University and, as Francisco de Palacios deposed at Valladolid
