Though it may well be supposed that Gualberto was not unassisted in his efforts, yet all such individual exertions, dependent upon persuasion alone, could be but limited in their influence and temporary in their results. Reform, to be universal and permanent, required to be authoritative in its character and to proceed from above downward. The papacy itself must cease to be a scandal to Christendom, and must be prepared to wield the awful force of its authority, seconded by the moral weight of its example, before disorders so firmly rooted could be attacked with any hope of success. In 1044, Benedict IX. was driven out of Rome by a faction of rebels or patriots, who elected Silvester III. as pontiff in his place. A sudden revolution sent Silvester into exile, and brought Benedict back, who, to complete the confusion, sold the papal dignity to a new aspirant, known as Gregory VI. The transaction was not one which could decently be recognized by the church, and Benedict was held incapable of thus transferring the allegiance of Christendom or of depriving himself of his position. There were thus three popes, whose conflicting claims to reverence threw all Europe into the doubt and danger of schism, nor could the knotty question be solved by the power of distracted Italy. A more potent judge was required, and the decision was referred, as a matter of course, to the sagacious and energetic Emperor, Henry the Black, whose success in repressing the turbulence of the empire, and whose sincere reverence for the church gave reasonable promise of a happy solution of the tangled problem.[452] His proceeding was summary. The three competitors were unceremoniously dismissed, and Henry filled the vacancy thus created by the appointment of Suidger, Bishop of Bamberg, who assumed the name of Clement II. Henry III. was moved by a profound conviction that a thorough and searching reform was vitally necessary to the church. The conscientious severity of his character led him to have little toleration for the abuses and disorders which were everywhere so painfully apparent. How far his views were in advance of those generally entertained, even by ecclesiastical dignitaries, was clearly manifested as early as 1042, when Gebhardt, Bishop of Ratisbon, urged the claims of his favorite arch-priest Cuno for the vacant see of Eichstedt. Henry refused on the ground that Cuno was the son of a priest, and therefore by the established canons ineligible to the position. The reason, though unanswerable, was so novel that Gebhardt refused to accept it as the true one, and Henry, to pacify him, promised to nominate any other one of the Ratisbon clergy whom Gebhardt might select. The choice fell upon a young and unknown man, also named Gebhardt, whose abilities, brought into notice thus accidentally, rendered him afterwards more conspicuous as Pope Victor II.[453]
