A sharp distinction was already made between the officers of the Church, who were called the clergy, and the people, or laity. To the clergy was committed the government of the Church as well as the instruction of its members. In each of the Roman cities was a bishop, and at the head of the country communities, a priest (Latin, presbyter), who had succeeded to the original elders (presbyters) mentioned in the New Testament. Below the bishop and the priest were the lower orders of the clergy,—the deacon and sub-deacon,—and below these the so called minor orders—the acolyte, exorcist, reader, and doorkeeper. The bishop exercised a certain control over the priests within his territory. It was not unnatural that the bishops in the chief towns of the Roman provinces should be especially influential in church affairs. They came to be called archbishops, and might summon the bishops of the province to a council to decide important matters.
The first general council, 325. Position of the Bishop of Rome during this period.
In 311 the emperor Galerius issued a decree placing the Christian religion upon the same legal footing as paganism. Constantine, the first Christian emperor, carefully enforced this edict. In 325 the first general council of Christendom was called together under his auspices at Nicæa. It is clear from the decrees of this famous assembly that the Catholic Church had already assumed the form that it was to retain down to the present moment, except that there is no explicit recognition of the Bishop of Rome as the head of the whole church. Nevertheless, there were a number of reasons—to be discussed later—why the Bishop of Rome should sometime become the acknowledged ruler of western Christendom. The first of the Roman bishops to play a really important part in authentic history was Leo the Great, who did not take office until 440.[6]
The Church in the Theodosian Code.
Constantine's successors soon forbade pagan practices and began to issue laws which gave the Christian clergy important privileges. In the last book of the Theodosian Code, a great collection of the laws of the Empire, which was completed in 438, all the imperial decrees are to be found which relate to the Christian Church and the clergy. We find that the clergy, in view of their holy duties, were exempted from certain onerous offices and from some of the taxes which the laity had to pay. They were also permitted to receive bequests. The emperors themselves richly endowed the Church. Their example was followed by rulers and private individuals all through the Middle Ages, so that the Church became incredibly wealthy and enjoyed a far greater income than any state of Europe. The clergy were permitted to try certain cases at law, and they themselves had the privilege of being tried in their own church courts for minor criminal offenses. This last book of the Code begins with a definition of the Trinity; and much space is given to a description of the different kinds of unbelievers and the penalties attached to a refusal to accept the religion of the government.[7]
The Church survives the Empire.
In these provisions of the Theodosian Code the later mediæval Church is clearly foreshadowed. The imperial government in the West was soon overthrown by the barbarian conquerors, but the Catholic Church conquered and absorbed the conquerors. When the officers of the Empire deserted their posts the bishops stayed to meet the on-coming invader. They continued to represent the old civilization and ideas of order. It was the Church that kept the Latin language alive among those who knew only a rude German dialect. It was the Church that maintained some little education in even the darkest period of confusion, for without the ability to read Latin its services could not have been performed and its officers could not have carried on their correspondence with one another.
The Eastern Empire.
8. Although the Roman Empire remained one in law, government, and culture until the Germans came in sufficient force to conquer the western portions of it, a tendency may nevertheless be noticed some time before the conquest for the eastern and western portions to drift apart. Constantine, who established his supremacy only after a long struggle with his rivals, hoped to strengthen the vast state by establishing a second capital, which should lie far to the east and dominate a region very remote from Rome. Constantinople was accordingly founded in 330 on the confines of Europe and Asia.[8] This was by no means supposed to destroy the unity of the Empire. Even when Theodosius the Great arranged (395) that both his sons should succeed him, and that one should rule in the West and one in the East, he did not intend to divide the Empire. It is true that there continued to be thereafter two emperors, each in his own capital, but they were supposed to govern one empire conjointly and in "unanimity." New laws were to be accepted by both. The writers of the time do not speak of two states but continue to refer to "the Empire," as if the administration were still in the hands of one ruler. Indeed the idea of one government for all civilized mankind did not pass away but continued to influence men during the whole of the Middle Ages.
Although it was in the eastern part of the Empire that the barbarians first got a permanent foothold, the emperors at Constantinople were able to keep a portion of the old possessions of the Empire under their rule for centuries after the Germans had completely conquered the West. When at last the eastern capital of the Empire fell, it was not into the hands of the Germans, but into those of the Turks, who have held it since 1453.
