The claim of the Roman bishops to supremacy over the Christian world had a double basis. Certain passages in the New Testament, where St. Peter is represented as the rock on which the Church is built, the pastor of the sheep and lambs of the Lord, and the doorkeeper of the kingdom of heaven, appear to indicate that he was regarded by Christ as the chief of the Apostles. Furthermore, a well-established tradition made St. Peter the founder of the Roman Church and its first bishop. It was then argued that he passed to his successors, the popes, all his rights and dignity. As St. Peter was the first among the Apostles, so the popes were to be the first among bishops. Such was the doctrine of the Petrine supremacy, expressed as far back as the second century, strongly asserted by many popes during the Middle Ages, and maintained to-day by the Roman Church.

123. GROWTH OF THE PAPACY

PONTIFICATE OF LEO I, 440-461 A.D.

Up to the middle of the fifth century about forty-five bishops had occupied St. Peter's chair at Rome. The most eminent these was Leo the Great. When he became bishop, the Germans were overrunning the western provinces of the empire. The invaders professed the Arian faith, as we have seen, and often persecuted the orthodox Christians among whom they settled. At such a time, when the imperial power was growing weaker, faithful Catholics in the West naturally turned for support to the bishop of Rome. Leo became their champion against the barbarians. Tradition declares that he succeeded in diverting Attila from an attack on Rome, and when the Vandals sacked the city Leo also intervened to prevent its destruction. [14]

PONTIFICATE OF GREGORY I, 590-604 A.D.

After Leo, no important name occurs in the list of popes until we come to Gregory the Great. Gregory, as the son of a rich and distinguished Roman senator, enjoyed a good education in all the learning of the time. He entered public life and at an early age became prefect of Rome. But now, almost at the outset of his career, Gregory laid aside earthly ambition. He gave up his honorable position and spent the fortune, inherited from his father, in the foundation of monasteries and the relief of the poor. He himself became a monk, turned his palace at Rome into a monastery, and almost ruined his health by too great devotion to fasts and midnight vigils. Gregory's conspicuous talents, however, soon called him from retirement and led to his election as pope.

TEMPORAL POWER OF GREGORY

The work of Gregory lay principally in two directions. As a statesman he did much to make the popes virtual sovereigns at Rome and in Italy. At this time the Italian peninsula, overrun by the Lombards and neglected by the eastern emperor, was in a deplorable condition. The bishop of Rome seemed to be the only man who could protect the people and maintain order. Gregory had very great success in this task. He appointed governors of cities, issued orders to generals, drilled the Romans for military defense, and sent ambassadors to treat with the king of the Lombards. It was largely owing to Gregory's efforts that these barbarians were prevented from conquering central Italy.

GREGORY'S SPIRITUAL AUTHORITY

Gregory was no less eminent as a churchman. His writings and his personal influence greatly furthered the advancement of the Roman Church in the West. We find him sternly repressing heresies wherever they arose, aiding the conversion of Arian Visigoths in Spain and Arian Lombards in Italy, and sending out monks as missionaries to distant Britain. [15] He well deserved by these labors the title "Servant of the servants of God," [16] which he assumed, and which the popes after him have retained. The admiration felt for his character and abilities raised him, in later ages, to the rank of a saint.
