The characters of the men who filled the papal chair during this century, most of them of exemplary life, some of commanding genius, would alone suffice to constitute it a memorable era. “Upon the mind of Innocent I,” says Milman,
[418-461 A.D.]
Barbaric invasion, although resulting in the overthrow of many of the institutions of civilisation, and in widespread suffering and social deterioration, served but to enhance the influence and importance of the Roman see. The apparent fulfilment of prophecy, pagan as well as Christian, when the city was taken and sacked by Alaric (410), seemed to complete the effacement of the temporal power in Rome. Neither the western emperors nor the Gothic conquerors held their court in the ancient capital, where the pope was now at once the most important and conspicuous authority. In the African provinces, the demoralisation occasioned by the fierce controversies and dissensions concerning Pelagianism and Donatism compelled the Catholic communities to exchange their former attitude of haughty independence for one of suppliant appeal, and to solicit the intervention and counsel which they had before rejected. Such was the aspect of affairs in the West when Leo the Great (440-461), by some regarded as the true founder of the mediæval popedom, succeeded to the primacy. A citizen of Rome by birth, he exemplified in his own character many of the ancient Roman virtues—a tenacious adherence to tradition in matters of religious belief, an indomitable resolution in the assertion of the prerogatives of his office, and the austere practice of the recognised duties of social life. This rigid maintenance of orthodoxy had been instilled into him (or at least confirmed) by the exhortations of Augustine, with whom he had become personally acquainted when on a mission to the African province; and before his election to the papal office the celebrated Cassian had conceived so high an opinion of his virtues and abilities as to dedicate to him his treatise on the Incarnation. Regarded, indeed, simply as the able antagonist of the Manichæan and Eutychian heresies, and as the first author of the collect, Leo would fill no unimportant place in the annals of Latin Christendom; but his influence on church history in other respects is of a far deeper and more potent kind. In none was it followed by more important results than by the success with which he established the theory that all bishops who, in questions of importance, demurred to the decision of their metropolitan should be entitled to appeal to Rome. He obtained the recognition of this principle not only in Illyricum, as his predecessor Innocent had done, but also in Gaul; and the circumstances under which he did so in the latter province constitute the whole proceedings a memorable episode in church history.
