the Church scattered over the world proves herself to be that of the Apostles. But we are very far from being able to show that such a rigidly fixed collection of apostolic writings existed everywhere in the Church about the year 200. It is indeed continually asserted that the Antiochian and Alexandrian Churches had at that date a New Testament which, in extent and authority, essentially coincided with that of the Roman Church; but this opinion is not well founded. As far as the Church of Antioch is immediately concerned, the letter of Bishop Serapion (whose episcopate lasted from about 190 to about 209), given in Eusebius (VI. 12), clearly shows that Cilicia and probably also Antioch itself as yet possessed no such thing as a completed New Testament. It is evident that Serapion already holds the Catholic principle that all words of Apostles possess the same value to the Church as words of the Lord; but a completed collection of apostolic writings was not yet at his disposal.[109] Hence it is very improbable that Theophilus, bishop of Antioch, who died as early as the reign of Commodus, presupposed such a collection. Nor, in point of fact, do the statements in the treatise "ad Autolycum" point to a completed New Testament.[110] Theophilus makes diligent use of the Epistles of Paul and mentions the evangelist John (C. I. 1.) as one of the bearers of the Spirit. But with him the one canonical court of appeal is the Scriptures of the Old Testament, that is, the writings of the Prophets (bearers of the Spirit). These Old Testament Prophets, however, are continued in a further group of "bearers of the Spirit," which we cannot definitely determine, but which at any rate included the authors of the four Gospels and the writer of the Apocalypse. It is remarkable that Theophilus has never mentioned the Apostles. Though he perhaps regards them all, including Paul, as "bearers of the Spirit," yet we have no indication that he looked on their _Epistles_ as canonical. The different way he uses the Old Testament and the Gospels on the one hand and the Pauline Epistles on the other is rather evidence of the contrary. Theophilus was acquainted with the four Gospels (but we have no reference to Mark), the thirteen Epistles of Paul (though he does not mention Thessalonians), most probably also with the Epistle to the Hebrews, as well as 1st Peter and the Revelation of John. It is significant that no single passage of his betrays an acquaintance with the Acts of the Apostles.[111]
