In 1708 the Toledo tribunal arrested Fray Manuel de Paredes, a contemplative fraile, who encouraged mystic practices among his penitents, leading to several trials, which illustrate the increased severity visited upon these condemned forms of devotion.[133] The same tendency is visible soon afterwards at Córdova, where a little conventicle of _Molinistas alumbrados_ was discovered in the Dominican convent of San Pablo, under the leadership of a beata named Isabel del Castillo. Her disciples abandoned to her their free-will and all their faculties; they had no need of fasts and penances but could transfer their sins to her and the path of salvation lay through sensual indulgence. In the auto of April 24, 1718, there were seven of them penanced, Isabel being visited with two hundred lashes and perpetual prison; the friars were reconciled, deprived of their functions and imprisoned, some irremissibly and some perpetually, while the laymen had penances of various degrees of severity.[134] During this period there occurred a case deserving of consideration in some detail, not only because of the prominence of the culprit but because it affords a clearer view than others of the strange intermixture of sensuality and spirituality, which was distinctly known as Molinism, and of the self-deception which enabled men and women to indulge their passions while believing themselves to be living in the mystic altitude of Union with God. Perhaps this may partly be explicable by the teachings of the laxer morality, current in the sixteenth century and known under the general name of Probabilism, and by the distinction between material and formal sin, whereby that alone was mortal sin which the conscience recognized as such, the conscience being still further eased by refinements as to advertence and consent. In the skilful hands of the casuists, the boundaries between right and wrong became dangerously nebulous, and arguments were plentiful through which men could persuade themselves that whatever they chose to do was lawful.
