§ 30.10.

  1. Tatian, a Greek born in Assyria (according to Zahn, a Semite) while engaged as a rhetorician at Rome, was won to Christianity by Justin Martyr, according to Harnack about A.D. 150. As the fruit of youthful zeal, he published an Apologetical Λόγος πρὸς Ἕλληνας, in which he treats the Greek paganism and its culture with withering scorn for even its noblest manifestations, and shared with his teacher the hatred and persecution of the philosopher Crescens. His later written Εὐαγγέλιον διὰ τεσσάρων (§ [36, 7]) was a Gospel harmony, in which the removal of all reference to the descent of Jesus from the seed of David, according to the flesh, objected to by Theodoret, was occasioned perhaps more by antipathy to Ebionism than by any sympathy with Gnosticism. Zahn affirms, while Harnack decidedly denies, that this work was originally composed in Syriac. The exclusive use by the Syrians of the Greek name Diatessaron seems to afford a strong argument for a Greek original. Its general agreement with the readings of the so-called Itala (§ [36, 8]) witnesses to the West as the place of its composition.The introduction of a Syriac translation of it into church use in the East is to be explained by a longer residence of the author in his eastern home; and its neglect on the part of many of the Greek and Latin Church Fathers, and even their complete ignorance of it, may be accounted for by the fact that, while in the far East it was unsuspected, elsewhere it came to be branded as heretical (§ [27, 10]).[69]
  2. Athenagoras, about whose life we have no authentic information, in A.D. 177 addressed his Πρεσβεία (Intercessio) περὶ Χριστιανῶν to Marcus Aurelius, in which he clearly and convincingly disproves the hideous calumnies of Atheism, Ædipodean atrocities, Thyestean feasts (§ [22]), and extols the excellence of Christianity in life and doctrine. In the treatise Περὶ ἀναστάσεως νέκρων he proves, from the general philosophical rather than distinctively Christian standpoint, the necessity of resurrection from the vocation of man in connection with the wisdom, omnipotence and righteousness of God.
  3. Theophilus, Bishop of Antioch († after A.D. 180), was by birth a pagan. His writing Πρὸς Αὐτόλυκον περὶ τῆς τῶν Χριστιανῶν πίστεως is one of the most excellent apologetical treatises of this period. Autolycus was one of his heathen acquaintances. His commentaries and controversial works have been lost. Zahn, indeed, has sought to prove that an extant Latin Commentary on selected passages from the four Gospels in the allegorical style belonging to the first half of the 3rd century, and bearing the name of Theophilus of Antioch, is a substantially faithful translation of the authentic Greek original of A.D. 170. He has also called attention to the great importance of this commentary, not only for the oldest history of the Canon, Text and Exposition, but also for that of the church life, the development of doctrine and the ecclesiastical constitution, especially of the monasticism already appearing in those early times. But while Zahn reached those wonderful results from a conviction that the verbal coincidences of the Latin Church Fathers of the 3rd to the 5th centuries with the supposed Theophilus commentary were examples of their borrowing from it, Harnack has convincingly proved that this so-called commentary is rather to be regarded as a compilation from these same Latin Church Fathers made at the earliest during the second half of the 5th century.
  4. Finally, an otherwise unknown author Hermias wrote under the title Διασυρμὸς τῶν ἔξω φιλοσόφων (Irrisio gentilium philos.) a short abusive treatise, in a witty but superficial style, of which the fundamental principle is to be found in 1 Cor. iii. 19.
§ 31. The Theological Literature of the Old Catholic Age, A.D. 170-323.

From about A.D. 170, during the Old Catholic Age, scientific theology in conflict with Judaizing, paganizing and monarchianistic heretics progressed in a more vigorous and comprehensive manner than in the apologetical and polemical attempt at self-defence of Post-Apostolic Times. Throughout this period, however, the zeal for apologetics continued unabated, but also in other directions, especially in the department of dogmatics, important contributions were made to theological science. While these developments were in progress, there arose within the Catholic church three different theological schools, each with some special characteristic of its own, the Asiatic, the Alexandrian, and the North African.

§ 31.1. The Theological Schools and Tendencies.—The School of Asia Minor was the outcome of John’s ministry there, and was distinguished by firm grasp of scripture, solid faith, conciliatory treatment of those within and energetic polemic against heretics. Its numerous teachers, highly esteemed in the ancient church, are known to us only by name, and in many cases even the name has perished. Only two of their disciples resident in the West—Irenæus and Hippolytus—are more fully known.A yet greater influence, more widely felt and more enduring, was that of the Alexandrian School.[70] Most of its teachers were distinguished by classical culture, a philosophical spirit, daring speculativeness and creative power. Their special task was the construction of a true ecclesiastical gnosis over against the false heretical gnosis, and so the most celebrated teachers of this school have not escaped the charge of unevangelical speculative tendencies. The nursery of this theological tendency was especially this Catechetical School of Alexandria which from an institution for the training of educated Catechumens had grown up into a theological seminary. The North African School by its realism, a thoroughly practical tendency, formed the direct antithesis of the idealism and speculative endeavours of the Alexandrian. It repudiated classical science and philosophy as fitted to lead into error, but laid special stress upon the purity of Apostolic tradition, and insisted with all emphasis upon holiness of life and strict asceticism.—Finally, our period also embraces the first beginnings of the Antiochean School, whose founders were the two presbyters Dorotheus and Lucian.The latter especially gave to the school in its earlier days the tendency to critical and grammatico-historical examination of scripture. At Edessa, too, as early as the end of the 2nd century, we find a Christian school existing.

1. Church Fathers Writing in Greek.

§ 31.2. Church Teachers of the Asiatic Type.

  1. Irenæus, a pupil of Polycarp, was a native of Asia Minor. According to the Vita Polycarpi of Pionius he lived in Rome at the time of Polycarp’s death as a teacher, and it is not improbable that he had gone there in company with his master (§ [37, 2]). Subsequently he settled in Gaul, and held the office of presbyter at Lyons. During his absence at Rome as the bearer of a tract by the imprisoned confessors of Lyons on the Montanist controversy to the Roman bishop Eleutherus, Pothinus, the aged bishop of Lyons, fell a victim to the dreadful persecution of Marcus Aurelius which raged in Gaul. Irenæus succeeded him as bishop in A.D. 178. About the time and manner of his death nothing certain is known. Jerome, indeed, once quite casually designates him a martyr, but since none of the earlier Church Fathers, who speak of him, know anything of this, it cannot be maintained with any confidence. Gentleness and moderation, combined with earnestness and decision, as well as the most lively interest in the catholicity of the church and the purity of its doctrine according to scripture and tradition, were the qualities that make him the most important and trustworthy witness to his own age, and led to his being recognised in all times as one of the ablest and most influential teachers of the church and a most successful opponent of heretical Gnosticism. His chief work against the Gnostics: Ἔλεγχος καὶ ἀνατροπὴ τῆς ψευδονύμου γνώσεως (Adv. hæreses) in 5 books, is mainly an ex professo directed against the Valentinians and the schools of Ptolemy and Marcus There is appended to it, beyond what had been proposed at the beginning, a short discussion of the views of other Gnostics, the basis of which may be found in an older treatise, perhaps in the Syntagma of Justin. The last four books give the express scripture proofs to sustain the general confutation, without doing this, however, in a complete manner; at the same time there is rapid movement amid many digressions and excursuses. This work has come down to us in a complete form only in an old translation literally rendered in barbarous Latin, even to the reproduction of misunderstood words, which was used as early as by Tertullian in his treatise against the Valentinians. We are indebted to the writings of the heresiologists Hippolytus and Epiphanius for the preservation of many remarkable fragments of the original, with or without the author’s name. Of his other writings we have only a few faint reminiscences. Two epistles addressed to the Roman presbyter Florinus combat the Valentinian heresy to which Florinus was inclined.During the controversy about Easter (§ [37, 2]) he wrote several epistles of a conciliatory character, especially one to Blastus in Rome, an adherent of the Asiatic practice, and in the name of the whole Gallic church, he addressed a letter to the Roman bishop, Victor, and afterwards a second letter in his own name.[71]
