In 518 Justin I. succeeded Anastasius on the throne of Constantinople, and in the task of defending the empire against the Persians. And this task became every year more difficult, as the Greek population of his Egyptian and Asiatic provinces fell off in numbers. For some years after the division of the empire under the sons of Constantine, Antioch in Syria had been the capital from which Alexandria received the emperor’s commands. The two cities became very closely united; and now that the Greeks were deserting Antioch, a part of the Syrian church began to adopt the more superstitious creed of Egypt. Severus, Bishop of Antioch, was successful in persuading a large party in the Syrian church to deny the humanity of Christ, and to style Mary the mother of God. But the chief power in Antioch rested with the opposite party. They answered his arguments by threats of violence, and he had to leave the city for safety. He fled to Alexandria, and with him began the friendship between the two churches which lasted for several centuries. In Alexandria he was received with the honour due to his religious zeal. But though in Antioch his opinions had been too Egyptian for the Syrians, in Alexandria they were too Syrian for the Egyptians. The Egyptians, who said that Jesus had been crucified and died only in appearance, always denied that his body was liable to corruption. Severus, however, argued that it was liable to corruption before the resurrection; and this led him into a new controversy, in which Timotheus, the Alexandrian bishop, took part against his own more superstitious flock, and sided with his friend, the Bishop of Antioch. Severus has left us, in the Syriac language, the baptismal service as performed in Egypt. The priest breathes three times into the basin to make the water holy, he makes three crosses on the child’s forehead, he adjures the demons of wickedness to quit him, he again makes three crosses on his forehead with oil, he again blows three times into the water in the form of a cross, he anoints his whole body with oil, and then plunges him in the water. Many other natives of Syria soon followed Severus to Alexandria; so many indeed that as Greek literature decayed in that city, Syriac literature rose. Many Syrians also came to study the religious life in the monasteries of Egypt, and after some time the books in the library of the monastery at Mount Nit-ria were found to be half Arabic and half Syriac.

Justin, the new emperor, again lighted up in Alexandria the flames of discord which had been allowed to slumber since the publication of Zeno’s peace-making edict. But in the choice of the bishop he was not able to command without a struggle. In the second year of his reign, on the death of Timotheus, the two parties again found themselves nearly equal in strength; and Alexandria was for several years kept almost in a state of civil war between those who thought that the body of Jesus had been liable to corruption, and those who thought it incorruptible. The former chose Gaianas, whom his adversaries called a Manichean; and the latter Theodosius, a Jacobite, who had the support of the prefect; and each of these in his turn was able to drive his rival out of Alexandria.

Those Persian forces which in the last reign overran the Delta were chiefly Arabs from the opposite coast of the Red Sea. To make an end of these attacks, and to engage their attention in another quarter, was the natural wish of the statesmen of Constantinople; and for this purpose Anastasius had sent an embassy to the Homeritæ on the southern coast of Arabia, to persuade them to attack their northern neighbours. The Homeritæ held the strip of coast now called Hadramout. They were enriched, though hardly civilised, by being the channel along which much of the Eastern trade passed from India to the Nile, to avoid the difficult navigation of the ocean. They were Jewish Arabs, who had little in common with the Arabs of Yemen, but had frequent intercourse with Abyssinia and the merchants of the Red Sea. Part of the trade of Solomon and the Tyrians was probably to their coast. To this distant and little tribe the Emperor of Constantinople now sent a second pressing embassy. Julianus, the ambassador, went up the Nile from Alexandria, and then crossed the Red Sea, or Indian Sea as it was also called, to Arabia. He was favourably received by the Homeritæ. Arethas, the king, gave him an audience in grand barbaric state. He was standing in a chariot drawn by four elephants; he wore no clothing but a cloth of gold around his loins; his arms were laden with costly armlets and bracelets; he held a shield and two spears in his hands, and his nobles stood around him armed, and singing to his honour. When the ambassador delivered the emperor’s letter, Arethas kissed the seal, and then kissed Julianus himself. He accepted the gifts which Justin had sent, and promised to move his forces northward against the Persians as requested, and also to keep the route open for the trade to Alexandria.

Justinian, the successor of Justin in 527, settled the quarrel between the two Alexandrian bishops by summoning them both to Constantinople, and then sending them into banishment. But this had no effect in healing the divisions in the Egyptian church; and for the next half-century the two parties ranged themselves, in their theological or rather political quarrel, under the names of their former bishops, and called themselves Gaianites and Theodosians. Nor did the measures of Justinian tend to lessen the breach between Egypt and Constantinople. He appointed Paul to the bishopric, and required the Egyptians to receive the decrees of the council of Chalcedon.

After two years Paul was displaced either by the emperor or by his flock; and Zoilus was then seated on the episcopal throne by the help of the imperial forces. He maintained his dangerous post for about six years, when the Alexandrians rose in open rebellion, overpowered the troops, and forced him to seek safety in flight; and the Jacobite party then turned out all the bishops who held the Greek faith.

When Justinian heard that the Jacobites were masters of Egypt he appointed Apollinarius to the joint office of prefect and patriarch of Alexandria, and sent him with a large force to take possession of his bishopric. Apollinarius marched into Alexandria in full military dress at the head of his troops; but when he entered the church he laid aside his arms, and putting on the patriarchal robes began to celebrate the rites of his religion. The Alexandrians were by no means overawed by the force with which he had entered the city; they pelted him with a shower of stones from every corner of the church, and he was forced to withdraw from the building in order to save his life. But three days afterwards the bells were rung through the city, and the people were summoned to meet in the church on the following Sunday, to hear the emperor’s letter read. When Sunday came the whole city flocked to hear and to disobey Justinian’s orders. Apollinarius began his address by threatening his hearers that, if they continued obstinate in their opinions, their children should be made orphans and their widows given up to the soldiery; and he was as before stopped with a shower of stones. But this time he was prepared for the attack; this Christian bishop had placed his troops in ambush round the church, and on a signal given they rushed out on his unarmed flock, and by his orders the crowds within and without the church were put to rout by the sword, the soldiers waded up to their knees in blood, and the city and whole country yielded its obedience for the time to bishops who held the Greek faith.

Henceforth the Melchite or royalist patriarchs, who were appointed by the emperor and had the authority of civil prefects, and were supported by the power of the military prefect, are scarcely mentioned by the historian of the Koptic church. They were too much engaged in civil affairs to act the part of ministers of religion. They collected their revenues principally in grain, and carried on a large export trade, transporting their stores to those parts of Europe where they would bring the best price. On one occasion we hear of a small fleet belonging to the church of Alexandria, consisting of thirteen ships of about thirty tons burden each, and bearing ten thousand bushels of grain, being overtaken by a storm on the coast of Italy. The princely income of the later patriarchs, raised from the churches of all Egypt under the name of the offerings of the pious, sometimes amounted to two thousand pounds of gold, or four hundred thousand dollars. But while these Melchite or royalist bishops were enjoying the ecclesiastical revenues, and administering the civil affairs of the diocese and of the great monasteries, there was a second bishop who held the Jacobite faith, and who, having been elected by the people according to the ancient forms of the Church, equally bore the title of patriarch, and administered in his more humble path to the spiritual wants of his flock. The Jacobite bishop was always a monk. At his ordination he was declared to be elected by the popular voice, by the bishops, priests, deacons, monks, and all the people of Lower Egypt; and prayers were offered up through the intercession of the Mother of God, and of the glorious Apostle Mark. The two churches no longer used the same prayer-book. The Melchite church continued to use the old liturgy, which, as it had been read in Alexandria from time immemorial, was called the liturgy of St. Mark, altered however to declare that the Son was of the same substance with the Father. But the Koptic church made use of the newer liturgies by their own champions, Bishop Cyril, Basil of Cæsaræ, and Gregory Nazianzen. These three liturgies were all in the Koptic language, and more clearly denied the two natures of Christ. Of the two churches the Koptic had less learning, more bigotry, and opinions more removed from the teachings of the New Testament; but then the Koptic bishop alone had any moral power to lead the minds of his flock towards piety and religion. Had the emperors been at all times either humane or politic enough to employ bishops of the same religion as the people, they would perhaps have kept the good-will of their subjects; but as it was, the Koptic church, smarting under its insults, and forgetting the greater evils of a foreign conquest, would sometimes look with longing eyes to the condition of their neighbours, their brethren in faith, the Arabic subjects of Persia.

The Christianity of the Egyptians was mostly superstition; and as it spread over the land it embraced the whole nation within its pale, not so much by purifying the pagan opinions as by lowering itself to their level, and fitting itself to their corporeal notions of the Creator. This was in a large measure induced by the custom of using the old temples for Christian churches; the form of worship was in part guided by the form of the building, and even the old traditions were engrafted on the new religion. Thus the traveller Antonius, after visiting the remarkable places in the Holy Land, came to Egypt to search for the chariots of the Egyptians who pursued Moses, petrified into rocks at the bottom of the Red Sea, and for the footsteps left in the sands by the infant Jesus while he dwelt in Egypt with his parents. At Memphis he enquired why one of the doors in the great temple of Phtah, then used as a church, was always closed, and he was told that it had been rudely shut against the infant Jesus five hundred years before, and mortal strength had never since been able to open it.

The records of the empire declared that the first Cæsars had kept six hundred and forty-five thousand men under arms to guard Italy, Africa, Spain, and Egypt, a number perhaps much larger than the truth; but Justinian could with difficulty maintain one hundred and fifty thousand ill-disciplined troops, a force far from large enough to hold even those provinces that remained to him. During the latter half of his reign the eastern frontier of this falling empire was sorely harassed by the Persians under their king Chosroes. They overran Syria, defeated the army of the empire in a pitched battle, and then took Antioch. By these defeats the military roads were stopped; Egypt was cut off from the rest of the empire and could be reached from the capital only by sea. Hence the emperor was driven to a change in his religious policy. He gave over the persecution of the Jacobite opinions, and even went so far in one of his decrees as to call the body of Jesus incorruptible, as he thought that these were the only means of keeping the allegiance of his subjects or the friendship of his Arab neighbours, all of whom, as far as they were Christians, held the Jacobite view of the Nicene creed, and denied the two natures of Christ.

As the forces of Constantinople were driven back by the victorious armies of the Persians, the emperors had lost, among other fortresses, the capital of Arabia Nabataæ, that curious rocky fastness that well deserved the name of Petra, and which had been garrisoned by Romans from the reign of Trajan till that of Valens. On this loss it became necessary to fortify a new frontier post on the Egyptian side of the Elanitic Gulf. Justinian then built the fortified monastery near Mount Sinai, to guard the only pass by which Egypt could be entered without the help of a fleet; and when it was found to be commanded by one of the higher points of the mountain he beheaded the engineer who built it, and remedied the fault, as far as it could be done, by a small fortress on the higher ground. This monastery was held by the Egyptians, and maintained out of the Egyptian taxes. When the Egyptians were formerly masters of their own country, before the Persian and Greek conquests, they were governed by a race of priests, and the temples were their only fortresses.
