Perhaps the man to whom the church owed most for his energy and activity in promoting the cause of reform was the celebrated Robert Grosseteste, Bishop of Lincoln. The leading part which he took in the political troubles of the stormy reign of Henry III. has thrown his ecclesiastical character somewhat into the shade, and he is better known as the friend of Leicester than as the untiring churchman. Notwithstanding his consistent opposition to Henry III. and to the encroachments of the papacy, he was the inflexible enemy of clerical irregularities, and he enforced the decretals throughout his diocese with as firm a hand as that which he raised in defence of the rights of the nation and the privileges of the Anglican church. Thus, in 1251, he made a rigorous inquisition in his bishopric, forcing all his beneficed clergy to the observance of the strictest chastity, removing from their houses all suspected women, and punishing transgressors with deprivation. It is not easy to approve of his brutal expedient for testing the virtue of the inmates of his nunneries,[716] the adoption of which could only be justified and suggested by the conviction that general licentiousness was everywhere prevalent; and though such treatment of the spouses of Christ was to the last degree degrading, yet it was doubtless more efficacious than the ordeal of the Eucharist, which was frequently resorted to in special cases. Not only, however, did he thus endeavor to reform the morals of his flock, but he made the closest scrutiny into the character of applicants for ordination. In this he was largely aided by his ascetic friend and admirer, Adam de Marisco, and the correspondence between them shows not only the importance which they reasonably attached to the subject, but the sleepless vigilance required to counteract the prevalent immorality of the clergy, and the incredible laxity with which the patrons of livings bestowed the benefices in their gift.[717]
