The great movement in favour of Church reform, which had emanated from Cluny, had worked itself out along certain definite lines. It is important to ask how far it had succeeded in achieving its objects. We have seen that it was a movement of essentially monastic conception aimed at the purification of the secular clergy. And we have seen that the evil to be remedied had arisen from the imminent danger that the Church would be laicised and feudalised. From the highest to the lowest all ecclesiastical posts were at the disposition of laymen who treated them as a species of feudal fief, so that the holders, even if they were in Holy Orders (which was not always the case), regarded their temporal rights and obligations as the first consideration and, like all feudal tenants, tried to establish the right of hereditary succession in their holdings. Thus the work of the reformers had been of a double nature; it was not enough that they should aim at exorcising the feudal spirit from the Church, at banishing the feudal ideal from the minds of ecclesiastics: it was necessary to effect what was indeed a revolution, and to shake the whole organisation of the Church free from the trammels which close contact with the State had laid upon it. It began as a reformation of morals; it developed into a constitutional revolution. There was involved in the movement both an interference with what might be distinguished as private rights and also a readjustment of public relations. The reformers headed by the Pope ultimately decided to concentrate their efforts on the latter. Hence we may begin by enquiring how far they had succeeded in freeing episcopal elections from lay control. [Sidenote: Episcopal appointments.] There were three several acts of the lay authority in connection with the appointment of bishops to which the Church reformers took exception. The King or, by usurpation from him, the great feudal lord had acquired the right of nominating directly to the vacant see, to the detriment, and even the exclusion, of the old electoral rights of clergy and people; and while in some cases nobles nominated themselves without any thought of taking Holy Orders, frequently they treated the bishoprics under their control as appanages or endowments for the younger members of their family. Then, before the consecration, the bishop-nominate obtained investiture from the lay authority by the symbolic gifts of a ring and a pastoral staff or cross, not only of the lands and temporal possessions of the see, but also of the jurisdiction which emanated from the episcopal office. Finally, the prospective bishop took an oath to his lay lord, whether King or other, which was not only an oath of fealty such as any subject might be called upon to take, but was also an act of homage, and made him an actual feudal vassal and his church a kind of fief.
