B. B. Warfield on the Formation of New Testament Canon
B. B. Warfield’s magisterial essay “The Formation of the Canon of the New Testament” was published in 1892. You can find the essay here. It has also been included in the various editions of Warfield’s The Inspiration and Authority of the Bible.
Here a few gems from that essay.
Warfield reminds us that the apostolic church did not “invent” the idea of a canon of New Testament books. The church possessed a canon of inspired and authoritative books from the very beginning–the Old Testament. The church was, therefore, never without a “canon.”
In order to obtain a correct understanding of what is called the formation of the Canon of the New Testament, it is necessary to begin by fixing very firmly in our minds one fact which is obvious enough when attention is once called to it. That is, that the Christian church did not require to form for itself the idea of a “canon” — or, as we should more commonly call it, of a “Bible” — that is, of a collection of books given of God to be the authoritative rule of faith and practice. It inherited this idea from the Jewish church, along with the thing itself, the Jewish Scriptures, or the "Canon of the Old Testament." The church did not grow up by natural law: it was founded. And the authoritative teachers sent forth by Christ to found His church, carried with them, as their most precious possession, a body of divine Scriptures, which they imposed on the church that they founded as its code of law. No reader of the New Testament can need proof of this; on every page of that book is spread the evidence that from the very beginning the Old Testament was as cordially recognized as law by the Christian as by the Jew. The Christian church thus was never without a “Bible” or a “canon.”
Through the revelation of the gospel preached by the apostles, Warfield notes that the Holy Spirit added to the existing Old Testament canon during the apostolic age. During this period of its development, the church did not possess a “closed canon,” but “an increasing canon.”
But the Old Testament books were not the only ones which the apostles (by Christ's own appointment the authoritative founders of the church) imposed upon the infant churches, as their authoritative rule of faith and practice. No more authority dwelt in the prophets of the old covenant than in themselves, the apostles, who had been “made sufficient as ministers of a new covenant” [2 Cor. 3:6]; for (as one of themselves argued) “if that which passeth away was with glory, much more that which remaineth is in glory” [2 Cor. 3:11] Accordingly not only was the gospel they delivered, in their own estimation, itself a divine revelation, but it was also preached “in the Holy Ghost” (I Pet. i. 12); not merely the matter of it, but the very words in which it was clothed were "of the Holy Spirit" (I Cor. ii. 13). Their own commands were, therefore, of divine authority (I Thess. iv. 2), and their writings were the depository of these commands (II Thess. ii. 15). “If any man obeyeth not our word by this epistle,” says Paul to one church (II Thess. iii. 14), “note that man, that ye have no company with him.” To another he makes it the test of a Spirit-led man to recognize that what he was writing to them was "the commandments of the Lord" (I Cor. xiv. 37). Inevitably, such writings, making so awful [“authoritative”] a claim on their acceptance, were received by the infant churches as of a quality equal to that of the old “Bible”; placed alongside of its older books as an additional part of the one law of God; and read as such in their meetings for worship — a practice which moreover was required by the apostles (I Thess. v. 27; Col. iv. 16; Rev. i. 3). In the apprehension, therefore, of the earliest churches, the “Scriptures” were not a closed but an increasing “canon.” Such they had been from the beginning, as they gradually grew in number from Moses to Malachi; and such they were to continue as long as there should remain among the churches “men of God who spake as they were moved by the Holy Ghost.”
According to Warfield, the church did not create a new canon alongside the old by determining what ought to be included in it (or not). Rather, the church recognized the books of our present New Testament as they were given, and therefore added them to the existing books of the Old Testament canon. These books came from the apostolic circle under the inspiration of the Holy Spirit and therefore already possessed full authority as the word of God independently of the church’s recognition of them.
What needs emphasis at present about these facts is that they obviously are not evidences of a gradually-heightening estimate of the New Testament books, originally received on a lower level and just beginning to be tentatively accounted Scripture; they are conclusive evidences rather of the estimation of the New Testament books from the very beginning as Scripture, and of their attachment as Scripture to the other Scriptures already in hand. The early Christians did not, then, first form a rival “canon” of “new books” which came only gradually to be accounted as of equal divinity and authority with the “old books”; they received new book after new book from the apostolical circle, as equally “Scripture” with the old books, and added them one by one to the collection of old books as additional Scriptures, until at length the new books thus added were numerous enough to be looked upon as another section of the Scriptures.
