My growing experience in Christ’s church has borne out the reality that a significant portion of attendees in our communions have a declining confidence in the authority of Scripture. Their suspicions stem from various concerns, including issues of inerrancy, infallibility, and, last but not least, the canonicity of Scripture. In a culture steeped in relativism, skepticism toward any authoritative view of written literature is understandable. Even so, given the claims the Bible makes about itself, the nature of God, and reality itself, the question of canonicity must be addressed for us to trust the Bible’s claims upon our lives. The ability to say, “Thus says the Lord,” rests, in part, on how we answer the question of canonicity. Therefore, I aim to provide an answer to this concern.
First, the necessity of a canon for a religious community originates in the redemptive activity of God. He must graciously establish the relationship with His people that provides the context for a canon. Michael Horton expresses it this way: “God’s Word must first create the reality of which it speaks and then regulate it, as the Spirit brings the proper effect and response within His creation…God’s sacramental Word of judgment and grace creates the new Exodus people and then constitutes them as God’s nation by the canon of Holy Scripture.” For example, without God’s saving work for Israel in Egypt, there would be no context for a biblical relationship. In other words, without God setting Israel free, there would be no Mt. Sinai, where the people of God received the first installment of God’s Word.
Secondly, following God’s redemptive activity, He establishes a special relationship with His people through a covenant. A covenant is a contract of relationship between a suzerain (conquering king) and his vassals (rescued servants of the king). Horton explains that this contract “lays out the terms of the treaty between the Suzerain and vassals—the stipulations and sanctions toward His servants. This arrangement is based on the liberation of a people, which gives basis for the King’s imperial rights over our lives.” He continues, “Every covenant has a canon (‘rule’), and every community is defined by its constitution. Such a document, the Scriptures, actually constitutes a nation.” Therefore, the canon refers to the body of writings God has given to rule His church. For example, after sanctioning the Mosaic covenant, the Lord provided a permanent witness against the sins of the people through the Mosaic Law. This witness was placed in the Ark of God as a “rule” and guide to the people. Yet this communication was never intended to be a mere set of rules; as John Frame states, “God’s intention is to speak personal words to us, words that have more authority than any other. These words govern our use of all other words, all other sources of knowledge.”
Thirdly, given the multiple covenants in Israel’s history, the canon of Scripture has been a developing document. Scripture is “a deposit of an organic and unfolding canon…the Word that liberates and creates its society and also the rule under which that society flourishes.” At each covenantal stage, additions were made to the corpus of God’s Word. For example, in the covenant of creation, God provided instruction to Adam and Eve, along with natural law. The Mosaic covenant introduced the Ten Commandments (Exodus 20) and Deuteronomic Law (Deuteronomy 31:24). Subsequent additions included Joshua (Joshua 24:25-38), the historical books, and the prophetic writings. The best confirmation of the Old Testament canon comes from Jesus Himself, who frequently quoted and appealed to the Law, the Prophets, and other Old Testament writings. The passages Jesus cited affirm their authority. Frame highlights that the Old Testament speaks of a new covenant, which is fulfilled in Jesus, taught by Him and His apostles, and then transmitted through their disciples.
With the establishment of the New Covenant through Christ’s life, death, and resurrection, this pattern reaches its climax:
"For when God made a promise to Abraham, since he had no one greater by whom to swear, he swore by himself, saying, ‘Surely I will bless you and multiply you.’ And thus Abraham, having patiently waited, obtained the promise. For people swear by something greater than themselves, and in all their disputes an oath is final for confirmation. So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us. We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek." (Hebrews 6:13-20)
"Now the point in what we are saying is this: we have such a high priest, one who is seated at the right hand of the throne of the Majesty in heaven, a minister in the holy places, in the true tent that the Lord set up, not man. For every high priest is appointed to offer gifts and sacrifices; thus it is necessary for this priest also to have something to offer. Now if he were on earth, he would not be a priest at all, since there are priests who offer gifts according to the law. They serve a copy and shadow of the heavenly things. For when Moses was about to erect the tent, he was instructed by God, saying, ‘See that you make everything according to the pattern that was shown you on the mountain.’ But as it is, Christ has obtained a ministry that is as much more excellent than the old as the covenant he mediates is better, since it is enacted on better promises. For if that first covenant had been faultless, there would have been no occasion to look for a second.” (Hebrews 8:1-7)
Through Christ’s sacrifice, the New Covenant is inaugurated, offering an inheritance based on His perfect obedience and atoning work. Consequently, the New Testament canon developed as the Lord provided His continued revelation to His New Covenant temple—the Church. Horton points out that this provision follows a covenantal format: the “historical prologue” of the New Covenant is found in the Gospels, the Epistles provide apostolic interpretation, and Revelation presents a covenant lawsuit against the Church if found unfaithful to Christ, the covenant mediator. By A.D. 190-202, the accumulation of the New Testament canon was nearly complete. While no biblical text explicitly defines the final canon, historical evidence indicates remarkable agreement in the early church regarding its contents. The New Testament canon developed over the first few centuries of the Christian church as the early believers sought to preserve the authoritative teachings of Jesus and the apostles. Initially, the church relied on the oral teachings of the apostles and early written documents such as letters (epistles) and Gospels, which circulated among churches.
By the end of the 1st century, many of Paul’s letters and the four Gospels were already being read and respected as authoritative. However, a formal list of New Testament books was not yet established. As heresies (like Gnosticism) spread, the church increasingly recognized the need to clarify which writings were truly apostolic and doctrinally sound.
Key moments include:
Muratorian Fragment (late 2nd century): one of the earliest known lists of accepted books.
Church Fathers like Irenaeus, Tertullian, and Origen referenced a core group of authoritative texts.
Athanasius’ Easter Letter (367 AD): the first known list matching the 27 books of our New Testament today.
Councils of Hippo (393 AD) and Carthage (397 AD): confirmed the canon recognized by the broader church.
The canon was not decided by a single council but gradually recognized based on apostolic authorship, consistent theology, and widespread use in worship.
Despite the strong redemptive, biblical, and historical basis for the canon’s formation, our ultimate assurance rests on a supernatural foundation. The Westminster Confession of Faith (1.5) states:
"We may be moved and induced by the testimony of the Church to a high and reverent esteem of the Holy Scripture, and the heavenliness of the matter, the efficacy of the doctrine, the majesty of the style, the consent of all the parts, the scope of the whole (which is to give all glory to God), the full discovery it makes of the only way of man’s salvation, and many other incomparable excellencies. Yet, notwithstanding, our full persuasion and assurance of its infallible truth and divine authority is from the inward work of the Holy Spirit, bearing witness by and with the Word in our hearts."
Thus, Scripture is a self-attesting communication that must be interpreted by Scripture itself. Its message, in canonical form, remains “living and active,” continuously making itself known to the Church—the covenant community of the Triune God. We can trust this holy Word because its author is God Himself, and it has been affirmed throughout His redemptive history.
