Edessa, the metropolis of Mesopotamia, had remained an Oriental city till the third century, when it was made a Roman colony by Caracalla.[291:3] Its position on the confines of two empires gave it great ecclesiastical importance, as the channel by which the theology of Rome and Greece was conveyed to a family of Christians, dwelling in contempt and persecution amid a still heathen world. It was the seat of various schools; apparently of a Greek school, where the classics were studied as well as theology, where Eusebius of Emesa[291:4] had originally been trained, and where perhaps Protogenes taught.[291:5] There were also Syrian schools attended by heathen and Christian youths in common. The cultivation of the native language had been an especial object of its masters since the time of Vespasian, so that the pure and refined dialect went by the name of the Edessene.[291:6] At Edessa too St. Ephrem formed his own Syrian school, which lasted long after him; and there too was the celebrated Persian Christian school, over which Maris presided, who has been already mentioned as the translator of Theodore into Persian.[291:7] Even in the time of the predecessor of Ibas in the See (before A.D. 435) the Nestorianism of this Persian School was so notorious that Rabbula the Bishop had expelled its masters and scholars;[292:1] and they, taking refuge in a country which might be called their own, had introduced the heresy to the Churches subject to the Persian King.

Something ought to be said of these Churches; though little is known except what is revealed by the fact, in itself of no slight value, that they had sustained two persecutions at the hands of the heathen government in the fourth and fifth centuries. One testimony is extant as early as the end of the second century, to the effect that in Parthia, Media, Persia, and Bactria there were Christians who "were not overcome by evil laws and customs."[292:2] In the early part of the fourth century, a bishop of Persia attended the Nicene Council, and about the same time Christianity is said to have pervaded nearly the whole of Assyria.[292:3] Monachism had been introduced there before the middle of the fourth century, and shortly after commenced that fearful persecution in which sixteen thousand Christians are said to have suffered. It lasted thirty years, and is said to have recommenced at the end of the Century. The second persecution lasted for at least another thirty years of the next, at the very time when the Nestorian troubles were in progress in the Empire. Trials such as these show the populousness as well as the faith of the Churches in those parts,—and the number of the Sees, for the names of twenty-seven Bishops are preserved who suffered in the former persecution. One of them was apprehended together with sixteen priests, nine deacons, besides monks and nuns of his diocese; another with twenty-eight companions, ecclesiastics or regulars; another with one hundred ecclesiastics of different orders; another with one hundred and twenty-eight; another with his chorepiscopus and two hundred and fifty of his clergy. Such was the Church, consecrated by the blood of so many martyrs, which immediately after its glorious confession fell a prey to the theology of Theodore; and which through a succession of ages manifested the energy, when it had lost the pure orthodoxy of Saints.

The members of the Persian school, who had been driven out of Edessa by Rabbula, found a wide field open for their exertions under the pagan government with which they had taken refuge. The Persian monarchs, who had often prohibited by edict[293:1] the intercommunion of the Church under their sway with the countries towards the west, readily extended their protection to exiles, whose very profession was the means of destroying its Catholicity. Barsumas, the most energetic of them, was placed in the metropolitan See of Nisibis, where also the fugitive school was settled under the presidency of another of their party; while Maris was promoted to the See of Ardaschir. The primacy of the Church had from an early period belonged to the See of Seleucia in Babylonia. Catholicus was the title appropriated to its occupant, as well as to the Persian Primate, as being deputies of the Patriarch of Antioch, and was derived apparently from the Imperial dignity so called, denoting their function as Procurators-general, or officers in chief for the regions in which they were placed. Acacius, another of the Edessene party, was put into this principal See, and suffered, if he did not further, the innovations of Barsumas. The mode by which the latter effected those measures has been left on record by an enemy. "Barsumas accused Babuæus, the Catholicus, before King Pherozes, whispering, 'These men hold the faith of the Romans, and are their spies. Give me power against them to arrest them.'"[294:1] It is said that in this way he obtained the death of Babuæus, whom Acacius succeeded. When a minority resisted[294:2] the process of schism, a persecution followed. The death of seven thousand seven hundred Catholics is said by Monophysite authorities to have been the price of the severance of the Chaldaic Churches from Christendom.[294:3] Their loss was compensated in the eyes of the Government by the multitude of Nestorian fugitives, who flocked into Persia from the Empire, numbers of them industrious artisans, who sought a country where their own religion was in the ascendant.

That religion was founded, as we have already seen, in the literal interpretation of Holy Scripture, of which Theodore was the principal teacher. The doctrine, in which it formally consisted, is known by the name of Nestorianism: it lay in the ascription of a human as well as a Divine Personality to our Lord; and it showed itself in denying the title of "Mother of God," or θεοτόκος, to the Blessed Mary. As to our Lord's Personality, the question of language came into the controversy, which always serves to perplex a subject and make a dispute seem a matter of words. The native Syrians made a distinction between the word "Person," and "Prosopon," which stands for it in Greek; they allowed that there was one Prosopon or Parsopa, as they called it, and they held that there were two Persons. If it is asked what they meant by parsopa, the answer seems to be, that they took the word merely in the sense of character or aspect, a sense familiar to the Greek prosopon, and quite irrelevant as a guarantee of their orthodoxy. It follows moreover that, since the aspect of a thing is its impression upon the beholder, the personality to which they ascribed unity must have laid in our Lord's manhood, and not in His Divine Nature. But it is hardly worth while pursuing the heresy to its limits. Next, as to the phrase "Mother of God," they rejected it as unscriptural; they maintained that St. Mary was Mother of the humanity of Christ, not of the Word, and they fortified themselves by the Nicene Creed, in which no such title is ascribed to her.

Whatever might be the obscurity or the plausibility of their original dogma, there is nothing obscure or attractive in the developments, whether of doctrine or of practice, in which it issued. The first act of the exiles of Edessa, on their obtaining power in the Chaldean communion, was to abolish the celibacy of the clergy, or, in Gibbon's forcible words, to allow "the public and reiterated nuptials of the priests, the bishops, and even the patriarch himself." Barsumas, the great instrument of the change of religion, was the first to set an example of the new usage, and is even said by a Nestorian writer to have married a nun.[295:1] He passed a Canon at Councils, held at Seleucia and elsewhere, that bishops and priests might marry, and might renew their wives as often as they lost them. The Catholicus who followed Acacius went so far as to extend the benefit of the Canon to Monks, that is, to destroy the Monastic order; and his two successors availed themselves of this liberty, and are recorded to have been fathers. A restriction, however, was afterwards placed upon the Catholicus, and upon the Episcopal order.
