Here was what may be considered a dignus vindice nodus, the Church being divided, and an arbiter wanted. Such a case had also occurred in Africa in the controversy with the Donatists. Four hundred bishops, though but in one region, were a fifth part of the whole Episcopate of Christendom, and might seem too many for a schism, and in themselves too large a body to be cut off from God's inheritance by a mere majority, even had it been overwhelming. St. Augustine, then, who so often appeals to the orbis terrarum, sometimes adopts a more prompt criterion. He tells certain Donatists to whom he writes, that the Catholic Bishop of Carthage "was able to make light of the thronging multitude of his enemies, when he found himself by letters of credence joined both to the Roman Church, in which ever had flourished the principality of the Apostolical See, and to the other lands whence the gospel came to Africa itself."[284:1]
There are good reasons then for explaining the Gothic and Arian use of the word "Roman," when applied to the Catholic Church and faith, of something beyond its mere connexion with the Empire, which the barbarians were assaulting; nor would "Roman" surely be the most obvious word to denote the orthodox faith, in the mouths of a people who had learned their heresy from a Roman Emperor and Court, and who professed to direct their belief by the great Latin Council of Ariminum.

As then the fourth century presented to us in its external aspect the Catholic Church lying in the midst of a multitude of sects, all enemies to it, so in the fifth and sixth we see the same Church lying in the West under the oppression of a huge, farspreading, and schismatical communion. Heresy is no longer a domestic enemy intermingled with the Church, but it occupies its own ground and is extended over against her, even though on the same territory, and is more or less organized, and cannot be so promptly refuted by the simple test of Catholicity.
§ 2. The Nestorians.
The Churches of Syria and Asia Minor were the most intellectual portion of early Christendom. Alexandria was but one metropolis in a large region, and contained the philosophy of the whole Patriarchate; but Syria abounded in wealthy and luxurious cities, the creation of the Seleucidæ, where the arts and the schools of Greece had full opportunities of cultivation. For a time too, for the first two hundred years, as some think, Alexandria was the only See as well as the only school of Egypt; while Syria was divided into smaller dioceses, each of which had at first an authority of its own, and which, even after the growth of the Patriarchal power, received their respective bishops, not from the See of Antioch, but from their own metropolitan. In Syria too the schools were private, a circumstance which would tend both to diversity in religious opinion, and incaution in the expression of it; but the sole catechetical school of Egypt was the organ of the Church, and its Bishop could banish Origen for speculations which developed and ripened with impunity in Syria.

But the immediate source of that fertility in heresy, which is the unhappiness of the ancient Syrian Church, was its celebrated Exegetical School. The history of that School is summed up in the broad characteristic fact, on the one hand that it devoted itself to the literal and critical interpretation of Scripture, and on the other that it gave rise first to the Arian and then to the Nestorian heresy. If additional evidence be wanted of the connexion of heterodoxy and biblical criticism in that age, it is found in the fact that, not long after this coincidence in Syria, they are found combined in the person of Theodore of Heraclea, so called from the place both of his birth and his bishoprick, an able commentator and an active enemy of St. Athanasius, though a Thracian unconnected except by sympathy with the Patriarchate of Antioch.
The Antiochene School appears to have risen in the middle of the third century; but there is no evidence to determine whether it was a local institution, or, as is more probable, a discipline or method characteristic generally of Syrian teaching. Dorotheus is one of its earliest luminaries; he is known as a Hebrew scholar, as well as a commentator on the sacred text, and he was the master of Eusebius of Cæsarea. Lucian, the friend of the notorious Paul of Samosata, and for three successive Episcopates after him separated from the Church though afterwards a martyr in it, was the author of a new edition of the Septuagint, and master of the chief original teachers of Arianism. Eusebius of Cæsarea, Asterius called the Sophist, and Eusebius of Emesa, Arians of the Nicene period, and Diodorus, a zealous opponent of Arianism, but the master of Theodore of Mopsuestia, have all a place in the Exegetical School. St. Chrysostom and Theodoret, both Syrians, and the former the pupil of Diodorus, adopted the literal interpretation, though preserved from its abuse. But the principal doctor of the School was that Theodore, the master of Nestorius, who has just above been mentioned, and who, with his writings, and with the writings of Theodoret against St. Cyril, and the letter written by Ibas of Edessa to Maris, was condemned by the fifth Ecumenical Council. Ibas was the translator into Syriac, and Maris into Persian, of the books of Theodore and Diodorus;[286:1] and thus they became immediate instruments in the formation of the great Nestorian school and Church in farther Asia.
