The empire had now become the central point for all the German tribes of the West. The fact that the reigning family, the Merovingian race, had brought about its own destruction by its murderous atrocities had not affected the strength of the empire. Another family, that of Pepin of Heristal, had risen to supreme power—men of great energy, exalted force of character, and indomitable vigour. While other realms were sinking together into one common ruin, and the world seemed about to become the prey of the Moslem, it was this race, the house of Pepin of Heristal, afterwards called the Carlovingian, by which the first and effectual resistance was offered to the Mohammedan conquerors.
[395-715 A.D.]
The religious development then in progress was also equally favoured by the house of Pepin; we find it early maintaining the best understanding with Rome, and it was under the special protection of Charles Martel and Pepin le Bref that Boniface proceeded in his apostolic labours. Let us consider the temporal condition of the papal power. On the one side the East Roman Empire, weakened, fallen into ruin, incapable of supporting Christendom against Islamism, or of defending its own domains in Italy against the Lombards, yet continuing to claim supremacy even in spiritual affairs. On the other hand, we have the German nations full of the most vigorous life; victorious over the Moslem, attached with all the fresh ardour and trusting enthusiasm of youth to that authority of whose protecting and restricting influences they still felt the need, and filled with an unlimited and most freely rendered devotion.
Already Gregory II perceived the advantages he had gained; full of a proud self-consciousness, he writes thus to that iconoclast emperor, Leo the Isaurian: “All the lands of the West have their eyes directed towards our humility; by them are we considered as a God upon earth.” His successors became ever more and more impressed with the conviction that it was needful to separate themselves from a power (that of the Roman Empire) by which many duties were imposed on them, but which could offer them no protection in return. They could not safely permit a succession to the mere name and empire to fetter them, but turned themselves rather towards those from whom help and aid might also be expected. Thus they entered into strict alliance with those great captains of the West, the Frankish monarchs; this became closer and closer from year to year, procured important advantages to both parties, and eventually exercised the most active influence on the destinies of the world.
With the division of the empire in the year 395, the question of the Roman precedence of Constantinople was left for a time in abeyance; but in the West the authority of the bishop of Rome became more and more firmly established. In the following century the general conditions under which he was called upon to act became so materially modified as to constitute a new period in the history of our subject.
