Among many anomalies in the papacy, was the inverse ratio of its foreign influence and its domestic strength. Even whilst Rome and its vicinity had been most lawless, whilst the authority of popes in preceding centuries had been most fettered by faction, or most exposed to seditious outrage, their spiritual sway attained its height, and was acknowledged over Christendom without question. The reason is obvious. The religious spirit of the age bowed to ecclesiastical domination, while the factious temperament of the Romans fretted under all restraints of order. After their long exemption from the personal control of the popes, it became more than ever requisite to curb these feverish citizens, and to break down their robber noblesse: we shall hereafter see by what unscrupulous means, and at how great a sacrifice of character, this was finally effected by Alexander VI. But the popedom, whose unity had been rudely shaken by schism and absence, began, after its return to Rome, to suffer manifest inroads from the extension of their political individualities by the chief states of Europe. In order to maintain itself against this new tendency, it had recourse to a like policy; it sought by temporal aggrandisement to compensate the decay of spiritual authority. During its antecedent struggles with the empire, the cause of the Church had been that of freedom, its rallying cry the watchword of liberty. In those days its successes were hailed as a boon by the communes of Italy. Even the feudatories, whose jurisdiction had grown up under shelter of the imperial name, were glad to confirm their title by enrolling themselves as vassals of the Holy See. But when the successors of St. Peter began to develop ulterior aims,--when they descended into the arena of mere political ambition, and sought to aggrandise their territorial dominion by intrigue and arms,--a marked reaction took place. The princes and republics of the Peninsula stood on their defence against a new power of discord, the most fickle in its policy, the most unscrupulous in its expedients, that they had yet been called to resist. The ultra-montane nations pressed on to cope with or to conquer those degenerate Vicars of Christ, who, abandoning their high calling as shepherds and pacificators of Christendom, became its perturbators.
