Gradually, and perhaps almost imperceptibly, the church in the west in its government followed the civil divisions of the Roman empire. The bishop of the metropolis of a civil province, in time came to be regarded as having a general supervision of all the churches in that province, and soon it became the custom to style them metropolitans.

The bishops of the great cities of Rome, Constantinople, Alexandria, and Antioch, after the ascension of Constantine, were made to correspond to the four praetorian prefects created by Constantine in the civil government; and before the end of the fourth century received the title of patriarchs.[[12]] It is also said by Mosheim, though denied by other writers, that next to the patriarchs were bishops whose jurisdiction extended over several provinces and corresponded to the civil exarchs; next came the metropolitan bishops whose jurisdiction, as already stated, was limited to a single province, and corresponded to the governor of the provinces. The arch-bishops presided over a district including several bishoprics within a province; and lastly came the bishops of churches.

Concurrent with these changes arose the custom, first derived from the Greeks, of holding provincial councils. The bishops living in a single province met in council to confer upon mattes of common interest to their churches. At first the attending bishops looked upon themselves as merely the representatives of their respective churches, without further jurisdiction than to discuss and come to agreement on matters of common concern. But gradually they usurped the power to order by decree where at first they were wont to advise or entreat. Nor was it long ere the decrees of these provincial councils were forced upon the respective churches as laws to be implicitly obeyed.

There was some resistance to this from the lower clergy, but it was quickly overcome by the activity and ambition of the bishops, who were only too glad to escape the restraints imposed upon their movements by the doctrine of common consent. It is said also that as many changes occurred among the lower order of the clergy as among the bishops. The elders and deacons aping the conduct of their file leaders became too proud to attend to the humble duties of their offices, and hence a number of other officers were added to the church—subdeacons, acolythi, ostiarii, lectors, exorcists and copiatae[[13]]—while the elders and deacons spent much of their time in indolence and pleasure.

If the ambition of rival bishops distracted the church in the second and third centuries, much more did ambitious prelates—patriarchs and metropolitans—of the fourth and fifth centuries disturb its tranquility. They contended about the limits of their respective jurisdiction with all the bitterness of temporal kings seeking an enlargement of their dominions. They made conquests and reprisals upon each other in much the same spirit, and at times were not above resorting to violence to attain their ends. It soon happened that the patriarchs of Alexandria, Antioch and Jerusalem sank below their fellow patriarchs of Rome and Constantinople in wealth and dignity. The prelates of these latter cities fiercely contended for the title of universal bishop; and in that contest the bishop of Constantinople was not always unsuccessful.

Over the protest of Leo the Great, in the fifth century, the council of Chalcedon decreed that the bishop of "New Rome" ought to enjoy the same honors and prerogatives with the pontiff of ancient Rome, on account of the equal rank and dignity of the two cities. In the following century, encouraged by past successes the bishop of "New Rome,"—John, surnamed the Faster, because of the austerity of his life, assembled a council of eastern bishops on his own account, to decide on charges brought against the patriarch of Antioch. It was on this occasion that he made such an assumption of the title of acumenical or universal bishop, that Gregory the Great supposed him to be aiming at a supremacy over all the Christian churches. In spite of the opposition of Gregory, the Faster, sustained by the emperor, continued to wear the title, though, it is said, not in the sense that Gregory supposed. The contest continued from this time forward with little interruption until that fatal schism came between the east and the west with which the reader has already been made acquainted.[[14]] The patriarchs of New Rome retained their hold upon the east; but the decay, moral and spiritual, which blighted those churches steadily went on, until at the last, Mohammedan civilization displaced Christian civilization. The crescent rose triumphantly above the cross, and the east sank into a settled gloom out of which it has not yet been able to rise.

In the west it was otherwise. There all was activity. The Roman pontiffs not only sent their missionaries to the barbarians to preach the supremacy of the popes, but the barbarians came to Rome. They came with arms in their hands and as conquerors, it is true, and in the closing years of the fifth century obtained an easy victory over the western division of the empire. But if imperial Rome was vanquished, there arose above its ruins papal Rome, in majesty no less splendid than that possessed by imperial Rome in her palmiest days; and in the course of time the victorious barbarians bowed in as humble submission to the wand of the popes, as their ancestors had to the eagle-mounted standard of the emperors. Moreover, the barbarous nations that fell under the influence of the Roman missionaries were accustomed to hold their priests in a superstitious reverence. In portions of Western Europe the Druid priests had reigned over both people and magistrates, controlling absolutely the jurisdiction of the latter; and, in the case of the supreme priest, according to some authorities,[[15]] the reverence of the barbarians amounted to worship. This reverence, on their conversion to Christianity, was readily transferred to the supreme pontiff of the Catholic Church; and made possible that spiritual and temporal despotism before which monarchs trembled and the world stood in abject fear.

Having traced the rise of the Church of Rome to this point, it yet remains to say that the corruption of her clergy and members kept pace with the developing splendor of the hierarchy. The pride, ambition and wickedness which bishops and other ministers of the church practiced in the second and third centuries have already been pointed out, and at the same time it was suggested that in these matters there was not likely to be any improvement after ease and luxury—ever the panderers to immorality—had increased the appetite for sensual pleasures and supplied the means of gratification.

Early in the history of the church the morality of the times not only excused but justified lying and deceit whenever it was supposed that the interests of religion could be promoted by it; and hence the existence of that mass of childish fable and falsehood respecting the infancy and youth of Messiah, and the wonder-working power of the relics of the saints and martyrs which has brought the Christian religion into contempt. Not even the greatest and most pious teachers of the first five or six centuries are free from this leprosy;[[16]] and if such characters as Ambrose, Hilary, Augustine, Gregory Nazianzen, and Jerome are not free from it, how much more may we expect to find it a vice with men of less reputation!

The attempt to live in a state of celibacy gave rise to many scandals in the church. Ambitious of a peculiar sanctity, the clergy began to abstain from marriage, but not from the pleasures supposed to be peculiar to the married state. It became the custom for the priests to live with "sub-introduced women," who "passed as sisters of the priests, the correctness of whose taste was often exemplified by the remarkable beauty of their sinful partners."[[17]] It is only fair to say that a law of Honorius condemned this practice, but it is to be feared that the only effect of the law upon those undertaking to live in the unnatural condition which celibacy imposes was merely to drive the practice from the public gaze.
