There is really no contradiction between this sense of a high calling and mission, with a special endowment corresponding to it, and the other fact that the writings from this age that have come down to us are all (except perhaps the Apocalypse, and even the Apocalypse, in some degree, as we see by the letters to the Seven Churches) strictly occasional and natural in their origin. The lives and actions of apostles and prophets were in their general tenor like those of other men; it was only that, for the particular purpose of their mission, they found themselves carried beyond and above themselves. St Paul himself knew when he was speaking by the Spirit, and when he was not; and we too can recognize to some extent when the afflatus comes upon him. It is fortunate that this should be so clearly marked in his epistles, because it enables us to argue by analogy to the other writers. When we come to historical books like the third Gospel and the Acts, we find the writer just pursuing the ordinary methods of history, and not claiming to do anything more (Luke i. 1-4). With the methods of history, these writers were naturally exposed to the risks and chances of error attendant upon those methods. There was hot at first among the writers any idea that they were composing an infallible narrative. The freedom with which they used each other’s work, and with which the early texts were transmitted, excludes this. But there was the idea that the whole movement of the Church to which they gave expression was in a special sense divine. And this belief was the fundamental principle that determined the marking off of the writings of the first, or apostolic, age from the rest.
At the same time it must not be supposed that a hard and fast line can be drawn beyond which the spiritual stimulus of this first age ceased. The writings of Clement of Rome (A.D. 97) and of Ignatius (c. A.D. 110) mark the transition. Ignatius, for instance, clearly distinguishes between his own position and that of the apostles: “I do not enjoin you. as Peter and Paul did. They were Apostles, I am a convict; they were free, but I am a slave to this very hour” (Rom. iv. 3). And yet, none the less, Ignatius is conscious of acting and speaking at times from a kind of inspiration. “Even though certain persons desired to deceive me after the flesh, yet the spirit is not deceived, being from God; for it knoweth whence it cometh and where it goeth, and it searcheth out the hidden things. I cried out, when I was among you; I spake with a loud voice, with God’s own voice, give ye heed to the bishops, and the presbyters and deacons” (Philadelph. vii. 1). In like manner Clement, in two places (lix. 1, lxiii. 2), writes as though God were speaking through him.
2. Collection.—Concurrently with the tendency to discriminate between the higher authority of certain writings and the lower authority of others, there was also a tendency to collect and group together writings of the first class. The earliest example of this tendency is in the case of the Pauline Epistles. Marcion, we know (c. A.D. 140), had a collection of ten out of thirteen, in the order, Gal., 1 and 2 Cor., Rom., 1 and 2 Thess., Laodic. (= Eph.), Col., Phil., Philem. We observe that the Pastorals are omitted. But it is highly probable that the collection went back a full generation before Marcion. The short Epistle of Polycarp contains references or allusions to no less than nine out of the thirteen epistles, including 2 Thess., Eph., 1 and 2 Tim. Ignatius, writing just before, gives clear indications of six, including 1 Tim. and Titus. The inference lies near at hand that both writers had access to the full collection of thirteen, not omitting the Pastorals. Polycarp (ad Phil. xiii. 2) shows how strong was the interest in collecting the writings of eminent men.
It of course did not follow that, because the letters of St Paul were collected, they were therefore regarded as sacred. The feeling towards them at first would be simply an instinct of respect and deference; but we have seen above that the essential conditions of the higher estimate were present all along, and were only waiting to be recognized as soon as reflective thought was turned upon them. This process appears to have been going on throughout the middle years of the 2nd century.
The famous passage of Irenaeus (Adv. Haer. iii. 15. 8) assumes the possession by the Church of four authoritative Gospels and no more. This is the general view of the Church of his time, except the little clique known as the Alogi who rejected the Fourth Gospel, and Marcion, who only recognized St Luke. But here again, we may go back some way farther. Irenaeus writes (c. A.D. 185) as though the Four Gospels had held the field as far back as he can remember. About A.D. 170 Tatian, the disciple of Justin, composed out of these Gospels his Diatessaron. If Justin used any other Gospel, his use of it was very subordinate. Practically we may say that the estimate of the Four to which Tatian and Irenaeus testify must have been well established by the middle of the century, though sporadic instances may be found of the use of other Gospels that did not become canonical. The sifting out of these was proceeding steadily and gradually, and by the end of the century it may be regarded as complete.
We must make allowance for the existence of this margin, and for the blurring of the boundary-line that goes along with it. We cannot claim for the Church absolute sureness of judgment as to what falls on one side of the line and what on the other. It is possible, e.g., that a mistake has been made in the case of 2 Peter, which, however, is edifying enough. It is not less possible that writings like 1 Clem, and Epp. Ignat. are not inferior in real religious value to the Epistle of Jude. But, broadly speaking, the judgment of the early Church has been endorsed by that of after ages.
Harnack raises an interesting question (Reden u. Aufsätze. ii. 239 ff.), how it came about that Four Gospels were recognized, and not only one. There are many indications early in the 2nd century of a tendency towards the recognition of a single Gospel; for instance, there are the local Gospels according to Hebrews, according to Egyptians; Marcion had but one Gospel, St Luke, the Valentinians preferred St John and so on; Tatian reduced the Four Gospels to one by means of a Harmony, and it is possible that something of the kind may have existed before he did this. There is probably some truth in the view that the Church clung to its Four Gospels as a weapon against Gnosticism; it could not afford to reduce the number of its documents. But, over and above this, there was probably something in the circumstances in which the canonical Gospels were composed, and in their early history, which gave them a special prestige in the eyes of the faithful. The story which Eusebius quotes from Clement of Alexandria (H.E. vi. 14) seems to point to something of the kind.
3. Influences at work.—The whole process of the formation of the New Testament was steady and gradual. The critical period, during which the conception grew up of the New Covenant with its sacred book by the side of the Old Covenant, which in its written embodiment we call the Old Testament, extends roughly over the 2nd century. By the last decades of that century a preliminary list of these new Sacred Books had been formed and placed by the side of the Old with substantially the same attributes. We must briefly sketch the process by which this came about, tracing the causes which led to the result and indicating the manner in which they operated.
We have seen that the ultimate cause was the consciousness on the part of the Church that the first age of its own history was characterized by spiritual workings more intense than other times. This feeling had been instinctive, and it found expression in several ways, each one of them partial, when taken alone, but obtaining their full effect in combination. It should be understood that the goal towards which events were moving all the time was the equalizing of the New Testament with the Old Testament.
(a) Public Reading.—From the first the way in which the Epistles of Paul were brought to the knowledge of the churches to which they were addressed was by reading in the public assemblies for worship. This was done by the direction of the apostle himself (1 Thess. v. 27; Col. iv. 16). At first any writing that was felt to be useful for edification was read in this way, especially if it had local associations (cf. Dionysius of Corinth, ap. Eus. H.E. iv. 23. 11). But, as worship became more thoroughly organized, it was invested with increasing solemnity; the freedom of choice was gradually restricted; and inasmuch as lections were regularly taken from the Old Testament, it was only natural that other lections read alongside of them should gradually be placed upon the same footing.
