With the acceptance of Christianity as the official religion of the Empire the organisation of the Church tended to follow the arrangements for purposes of civil government. And when at a later period civil society was gradually organising itself on that hierarchical model which we know as feudalism, the Church, in the persons of its officers, was tending to become not so much the counterpart of the State as an integral part of it. For the clergy, as being the only educated class, were used by the Kings as civil administrators, and on the great officials of the Church were bestowed extensive estates which should make them a counterpoise to the secular nobles. In theory the clergy and people of the diocese still elected their bishop, but in reality he came to be nominated by the King, at whose hands he received investiture of his office by the symbolic gifts of the ring and the pastoral staff, and to whom he did homage for the lands of the see, since by virtue of them he was a baron of the realm. Thus for all practical purposes the great ecclesiastic was a secular noble, a layman. He had often obtained his high ecclesiastical office as a reward for temporal service, and had not infrequently paid a large sum of money as an earnest of loyal conduct and for the privilege of recouping himself tenfold by unscrupulous use of the local patronage which was his.

Furthermore, in contravention of the canons of the Church, the secular clergy, whether bishops or priests, were very frequently married. The Church, it is true, did not consecrate these marriages; but, it is said, they were so entirely recognised that the wife of a bishop was called Episcopissa. There was an imminent danger that the ecclesiastical order would shortly lapse into an hereditary social caste, and that the sons of priests inheriting their fathers' benefices would merely become another order of landowners.
[Sidenote: Church reform.]
Thus the two evils of traffic in ecclesiastical offices, shortly stigmatised as simony and concubinage—for the laws of the Church forbade any more decent description of the relationship—threatened to absorb the Church within the State. Professional interests and considerations of morality alike demanded that these evils should be dealt with. Ecclesiastical reformers perceived that the only lasting reformation was one which should proceed from the Church herself. It was among the secular clergy, the parish priests, that these evils were most rife. The monasteries had also gone far away from their original ideals; but the tenth century had witnessed the establishment of a reformed Benedictine rule in the Congregation of Cluny, and, in any case, it was in monastic life alone that the conditions seemed suitable for working out any scheme of spiritual improvement. The Congregation of Cluny was based upon the idea of centralisation; unlike the Abbot of the ordinary Benedictine monastery, who was concerned with the affairs of a single house, the Abbot of Cluny presided over a number of monasteries, each of which was entrusted only to a Prior. Moreover, the Congregation of Cluny was free from the visitation of the local bishops and was immediately under the papal jurisdiction. What more natural than that the monks of Cluny should advocate the application to the Church at large of those principles of organisation which had formed so successful a departure from previous arrangements in the smaller sphere of Cluny? Thus the advocates of Church reform evolved both a negative and a positive policy: the abolition of lay investiture and the utter extirpation of the practice of clerical marriages were to shake the Church free from the numbing control of secular interests, and these were to be accomplished by a centralisation of the ecclesiastical organisation in the hands of the Pope, which would make him more than a match for the greatest secular potentate, the successor of Caesar himself.
[Sidenote: Chances of reform.]
It is true that at the beginning of the eleventh century there seemed little chance of the accomplishment of these reforms. If the great secular potentates were likely to cling to the practice of investiture in order to keep a hold over a body of landowners which, whatever their other obligations, controlled perhaps one-third of the lands in Western Christendom; yet the Kings of the time were not unsympathetic to ecclesiastical reform as interpreted by Cluny. In France both Hugh Capet (987-96) and Robert (996-1031) appealed to the Abbot of Cluny for help in the improvement of their monasteries, and this example was followed by some of their great nobles. In Germany reigned Henry II (1002-24), the last of the Saxon line, who was canonised a century after his death by a Church penetrated by the influences of Cluny. It was the condition of the Papacy which for nearly half a century postponed any attempt at a comprehensive scheme of reform. Twice already in the course of the tenth century had the intervention of the German King, acting as Emperor, rescued the see of Rome from unspeakable degradation. But for nearly 150 years (904-1046), with a few short interludes, the Papacy was the sport of local factions. At the beginning of the eleventh century the leaders of these factions were descended from the two daughters of the notorious Theodora; the Crescentines who were responsible for three Popes between 1004 and 1012, owing their influence to the younger Theodora, while the Counts of Tusculum were the descendants of the first of the four husbands who got such power as they possessed from the infamous Marozia. The first Tusculan Pope, Benedict VIII (1012-24), by simulating an interest in reform, won the support of Henry II of Germany, whom he crowned Emperor; but in 1033 the same faction set up the son of the Count of Tusculum, a child of twelve, as Benedict IX. It suited the Emperor, Conrad II, to use him and therefore to acknowledge him; but twice the scandalised Romans drove out the youthful debauchee and murderer, and on the second occasion they elected another Pope in his place. But the Tusculan influence was not to be gainsaid. Benedict, however, sold the Papacy to John Gratian, who was reputed a man of piety, and whose accession as Gregory VI, even though it was a simoniacal transaction, was welcomed by the party of reform. But Benedict changed his mind and attempted to resume his power. Thus there were three persons in Rome who had been consecrated to the papal office. The Archdeacon of Rome appealed to the Emperor Conrad's successor, Henry III, who caused Pope Gregory to summon a Council to Sutri. Here, or shortly afterwards at Rome, all three Popes were deposed, and although Benedict IX made another attempt on the papal throne, and even as late as 1058 his party set up an anti-pope, the influence of the local factions was superseded by that of a stronger power.
[Sidenote: Imperial influence.]
But the alternative offered by the German Kings was no more favourable in itself to the schemes of the reformers than the purely local influences of the last 150 years. As Otto I in 963, so Henry III in 1046 obtained from the Romans the recognition of his right, as patrician or princeps, to nominate a candidate who should be formally elected as their bishop by the Roman people; and as Otto III in 996, so Henry III now used his office to nominate a succession of men, suitable indeed and distinguished, but of German birth. This was not that freedom of the Church from lay control nor the exaltation of the papal office through which that freedom was to be maintained. Indeed, so long as fear of the Tusculan influence remained, deference to the wishes of the German King, who was also Emperor, was indispensable, and when that King was as powerful as Henry III it was unwise to challenge unnecessarily and directly the exercise of his powers.
