Many causes contributed to bring about a relaxation of discipline in many of the religious orders. The uncanonical appointment of abbots, the union of various abbacies in the hands of a single individual, the custom of holding abbacies /in commendam/, and the wholesale exemption from episcopal authority for which many of the religious orders contended, are sufficient to account for this general relaxation. The state of the various houses and provinces even belonging to the same order depended largely on the character of the superiors, and hence it is not fair to judge one country or one province, or even one house, by what happened in other countries, provinces, or houses. Hence arises the difficulty of arriving at any general conclusion about the religious houses. It is safe, however, to say that with the exception of the Carthusians all the older orders required reform. From the beginning of the fifteenth century attempts were made to restore the old discipline in the Benedictine communities and with considerable success. The Carmelites were divided into two main branches, the Calced and the Discalced; the Franciscans were divided into three main bodies, the Conventuals, the Observants, and the Capuchins; the Dominicans made various efforts to restore the ancient discipline especially from about the beginning of the fifteenth century; while many of the Augustinians who were determined on reform established new congregations, as for example, the Discalced Augustinian Hermits, who spread themselves over France, Spain, and Portugal. In addition, various new congregations, amongst them the Oblates founded in 1433 by St. Francisca Romana, and the Hermit Brothers in 1435 by St. Francis of Paula, were established to meet the necessities of the age.[9] Unfortunately the endless disputes between the religious and secular clergy[10] at this period tended to distract the attention of both from their spiritual work, and to give rise to considerable disorder and discontent. On the one side, men like the Paris professor, John Poilly and Richard Fitzralph, Archbishop of Armagh, were too extreme and seemed inclined to leave to the religious orders no place in the ministration of the Church, while on the other, some of the religious, such as the Franciscan, John von Gorrel, wished to assert for themselves complete independence of episcopal control. Various attempts were made by Boniface VIII., Benedict XI., Alexander V., John XXII., Calixtus III., Sixtus IV., and by the Councils of Constance and Basle to settle these disputes, but without much permanent result. It was only in the eleventh session of the Fifth Lateran Council (1516) that Leo X. promulgated the decrees, which in substance hold good at the present time, fixing the relation between the bishops and the regular clergy.[11]
