How do Protestants Know They Have the Correct Canon?

Perhaps one of the most common challenges raised by Roman Catholic and Orthodox apologists is this:

“How do you know that you have the correct canon of Scripture?” or “Who canonized the Bible, and when?”

These questions are often presented in debates, taken as though they expose a fundamental weakness in Protestant Bibliology. Roman Catholic and Orthodox proponents often assert that Protestants have borrowed or “piggybacked” off of tradition in order to establish their canon of Scripture. They assert that unless an infallible Church or Holy Tradition declares which books belong in the Bible, Protestants have no basis for knowing what Scripture actually is.

In a recent debate that I listened to between Fr. Ananias and Matt Slick, Fr. Ananias wouldn’t even allow Matt Slick to appeal to the Scriptures until he had defended the basis for the Protestant canon. This shows the importance of a properly defended Protestant view of canonization. Because this is a blog post and not a book, I refer you to other works that delve more deeply into this subject: Canon Revisited: Establishing the Origins and Authority of the New Testament Books by Michael J. Kruger; The Canon of Scripture by F. F. Bruce and A General Introduction to the Bible by Norman Geisler and William Nix.

Let’s return to the assertion made above: that unless an infallible Church or Holy Tradition declares which books belong in the Bible, Protestants have no basis for knowing what Scripture actually is. I am convinced this sort of thinking rests upon a false premise. The issue is not whether the Church recognized the canon, the issue is what “canonization” actually means and how various traditions have dealt with the issue of canonization for both Old and New Testaments.

I am convinced that this is essentially a loaded question and is therefore an unhelpful question in moving the discussion forward. The question “Who canonized the Bible?” assumes that the Church somehow made certain books into Scripture. Protestants have always rejected that assumption. God alone makes Scripture Scripture through the act of divine inspiration.

2 Timothy 3:16-17 LSB
All Scripture is God-breathed and profitable for teaching, for reproof, for correction, for training in righteousness, 17 so that the man of God may be equipped, having been thoroughly equipped for every good work.

The Church cannot breathe out Scripture, only God can breathe out scripture. The Church cannot elevate an uninspired document into the Word of God, neither can they reject what is inspired. Rather, Protestants affirm what may be called authoritative or ministerial recognition. This simply means that the Church recognizes and bears witness to books that already possess divine authority because they are inspired by God.

An example may help: A jeweler identifies a genuine diamond because he recognizes what a genuine diamond is, but he does not create the diamond. Likewise, the Church did not create the canon; she merely recognized the books God had already inspired.

These questions will help to show where the divide is between Protestants, Roman Catholics, and Orthodox. Let’s put them side by side to compare:

Question	Protestant	Roman Catholic	Orthodox
What makes a book Scripture?	Divine inspiration	Divine inspiration	Divine inspiration
Who recognizes the canon?	The universal Church under God’s providence	The Magisterium	The Church through Holy Tradition
Does recognition create authority?	No	No	No
What gives certainty about the canon?	God’s providence and the Church’s recognition	The infallible Magisterium	Holy Tradition and the Church
Role of councils	Witnesses to the canon	Authoritative definitions	Reception and ratification

If we were to reduce the general area of disagreement down to something bite-sized it would look like this:

Protestant	Roman Catholic / Orthodox
Authoritative or Ministerial recognition (the Church serves and recognizes the Word)	Authoritative or Magisterial Determination (the Church authoritatively determines the canon)

Protestants see the Church as a servant and witness of Scripture, whereas Roman Catholics and Orthodox assign the Church an epistemic role in establishing which books are to be received as canonical.

The Protestant model is that God inspires -> The books possess authority immediately -> the universal Church recognizes what God has already done -> Councils publicly confess that recognition.

Something important must be noted here. If every council had been wrong in its assessment, Paul’s letter to the Romans would still have been Scripture. Why? Because councils don’t make/create/determine Scripture.

This means the fundamental divide is that under Protestantism, the Church recognizes Scripture, because Scripture is authoritative. Under Roman Catholic / Orthodox teaching, the faithful know which books are Scripture because the Church authoritatively tells them.

Protestants agree that the Church has an important role in recognizing, preserving, proclaiming, and transmitting the Scriptures. We disagree that the Church is the ultimate epistemic ground for knowing what Scripture is.

Let’s look at this from an epistemological angle. Suppose that someone asks: “Why is Romans Scripture?” The Protestant would answer: Because God inspired Romans, and the Church recognizes God’s work (my sheep hear my voice). The Roman Catholic or Orthodox would answer: Because God inspired Romans, and the Church and Holy Tradition authoritatively tells us Romans belongs in the canon. The follow-up question to the Roman Catholic or Orthodox is: How do you know your Church possesses that authority? The answer will likely be: because the Church says it does. The epistemic justification therefore is viciously circular. There is no epistemological necessity that requires an infallible declaration or Holy Tradition before it can be known as God’s Word. The Church’s recognition depends upon Scriptures inspiration and God’s providence. Scripture’s inspiration does not depend upon the Church’s recognition.

A question for Roman Catholic and Orthodox proponents:

If every bishop in the 4th century had mistakenly rejected Romans, would Romans have ceased to be Scripture?

The answer must be a resounding no! The follow-up would be “well why not?” Protestants know it is because Scriptures authority is intrinsic, not derivative. It is infallible, and therefore it is self-authenticating. This means that the Church’s recognition is passive or responsive.

With that, we must begin to establish a criteria for canonicity as we begin to look at the canon of Scripture.

Criteria for Canonicity

In order to determine what books are a part of the canon of scripture, we need to establish some base level criteria for how the Jews (OT) and Christians (NT) would recognizes the voice of God and His inspired Word. The one unifying principle in both testaments was divine inspiration.

Old Testament Criteria for Recognition:

1.) Prophetic Authority – The book was written by a prophet or one speaking under prophetic authority (e.g., Moses, Samuel, Isaiah, Jeremiah).
2.) Agreed with Previous Divine Revelation – It was consistent with the revelation God had already given. God does not contradict Himself.
3.) Reception by the Covenant Community – It was received by Israel, the people entrusted with “the oracles of God” (Rom. 3:2).
4.) Internal Marks of Divine Authority – It bore the qualities of God’s Word (majesty, truthfulness, unity, efficacy), witnessed to by the Holy Spirit.
5.) New Testament use of the Old Testament – How did Jesus and the Apostles quote the Old Testament also validates which books were recognized.

This resulted in the recognition of the threefold Hebrew canon: The Law, The Prophets, The Writings. This recognition developed organically through God’s providence. There is no biblical or historical evidence that Israel convened a council to vote books into the canon.

New Testament Criteria for Recognition:

1.) Apostolic Authority – Written by an apostle or by someone writing under apostolic authority (e.g., Mark, Luke).
2.) Agreement with Apostolic Doctrine – Consistent with “the faith once for all delivered to the saints” (Jude 3).
3.) Agreement with Previous Revelation – Consistent with the Old Testament and the fulfillment of God’s redemptive plan in Christ.
4.) Reception by the Covenant Community – Received, copied, preserved, and publicly read by the churches founded upon apostolic teaching.
5.) Universal Reception – Widely recognized across the churches, not merely accepted by one local congregation or region.
6.) Internal Marks of Divine Authority – It bore the qualities of God’s Word (majesty, truthfulness, unity, efficacy), witnessed to by the Holy Spirit.

Jesus declared “My sheep hear my voice” (John 10:27). The Church recognizes the Shepherd’s voice because it is His voice. The Church does not bestow authority upon that voice. Recognition is not the source of authority, it is the response to authority.

Comparing Traditions

It is critical at this juncture to compare the various traditions and their canons. Protestants have 66 books. Roman Catholics have 73 books. Greek Orthodox generally have 76 books. Ethiopian Orthodox have 81 books. If the existence of an infallible Church or Holy Tradition necessarily yields one universally recognized canon, why do these traditions differ?

Tradition	Old Testament Books	New Testament Books	Total Books
Protestant	39	27	66
Roman Catholic	46	27	73
Eastern Orthodox	~49	27	76
Gregorian Orthodox	~50	27	77
Russian Orthodox	Varies	27	~76-77
Ethiopian Orthodox	46+	35	81

I’ve added some definitions below in order to help navigate the conversation:

Deuterocanonical & Apocrypha = “Roman Catholic Bibles have more Old Testament books than Protestant Bibles. These books are part of the Apocrypha or Deuterocanon. The word apocrypha means “hidden,” while the word deuterocanonical means “second canon.” The additional books are Tobit, Judith, Wisdom of Solomon, Ecclesiasticus (Sirach), Baruch (including the Letter of Jeremiah), and 1 and 2 Maccabees. Catholic Bibles also include additions to the books of Esther and Daniel. Other books, such as 1 Esdras, 2 Esdras, and the Prayer of Manasseh, are also part of the Apocrypha, but aren’t included in the Catholic Bible. Although Jews and Christians have read these books for centuries, their status as Scripture has been debated for centuries because they contain errors.”

https://www.gotquestions.org/apocrypha-deuterocanonical.html

Pseudepigrapha = “The pseudepigrapha are the books that attempt to imitate Scripture but that were written under false names. The term pseudepigrapha comes from the Greek pseudo, meaning “false,” and epigraphein, meaning “to inscribe,” thus, “to write falsely.” The pseudepigraphical books were written anywhere from 200 BC to AD 300. They are spurious works written by unknown authors who attempted to gain a readership by tacking on the name of a famous biblical character. Obviously, a book called the “Testament of Abraham” has a better chance of being read than the “Counterfeit Testament of an Unknown Author.””

https://www.gotquestions.org/pseudepigrapha.html

As we can see above, when traditions are compared there is quite a wide variety of thoughts regarding what encompasses the canon of the Old Testament Scripture. There is generally no consensus on the Old Testament except between Judaism and Protestantism. The idea that the church—either infallibly, or through Holy Tradition—has solidified agreement with each other on the canon of the Old Testament is false. Roman Catholics and Orthodox traditions do not agree on what constitutes the canon of the Old Testament, and this is because they cannot agree on the deuterocanonical and apocryphal works.

Granted, this doesn’t prove that the Protestants have the correct Old Testament canon, but it does dispel the idea that the Church by itself solves the canon question. The discussion simply moves one step back: Which Church has the authority to define the canon? Roman Catholicism and Orthodoxy do not agree, despite appealing to the early church for a solution.

As Protestants, we reject the apocryphal and deuterocanonical works for several good reasons:

1.) Jesus nor the Apostles ever quote from the deuterocanonical / apocryphal works. This is highly significant since they repeatedly quote from the Old Testament Scriptures. The New Testament contains hundreds of quotations and allusions from the Hebrew Scriptures, but not one quotation introduces the deuterocanonical or apocryphal books with any formula “It is written” or “Scripture says.”

“As I have previous noted, the NT has not a single clearly attested example of a citation—or even an indisputable indirect allusion—to an apocryphal writing as authoritative Scripture. This is amazing when one considers that the LXX was the favorite Bible of the apostolic church and that the authors of the various NT writings were demonstrably aware of the existence of the Alexandrian canon. All that can be reasonably deduced is that Jesus and the Apostles—along with mainstream Judaism—rejected the deuterocanonical books as nonscriptural.”
━━ Eugene H. Merrill, The Canonicity of the Old Testament in The World and the Word: An Introduction to the Old Testament (Nashville: B&H Academic, 2011), 99.

2.) The Jewish witness (Josephus, Rabbinic Literature, and the Qumran community) have all rejected the deuterocanonical / apocryphal works . If the Jews were entrusted with the oracles of God (Romans 3:1-2). The Jewish people preserved the Scriptures corresponding to the books of the Protestant Old Testament (counted as 24 books in the Tanakh rather than 39). The Protestant Old Testament contains the same books, different order, different divisions, but the same content. If the Jews, who were entrusted with the oracles of God, rejected these deuterocanonical books as inspired, why would we affirm them?

3.) The deuterocanonical / apocryphal works contain teachings that are not historically accurate. For instance, in Judith 1:5 there is a clear historical error:

Judith 1:5 Douay-Rheims Bible “Now in the twelfth year of his reign, Nabuchodonosor, king of the Assyrians, who reigned in Ninive the great city, fought against Arphaxad and overcame him.”

This verse states that Nebuchadnezzar (different spelling) was the king of the Assyrians, yet we know he was the king of Babylon.

4.) The deuterocanonical / apocryphal works contains theological errors. For instance, in Tobit 4:11 and Tobit 12:9 the texts teach salvation by works through almsgiving.

Tobit 4:11 Douay-Rheims Bible – For alms deliver from all sin, and from death, and will not suffer the soul to go into darkness.

Tobit 12:9 Douay-Rheims Bible – “For alms delivereth from death, and the same is that which purgeth away sins, and maketh to find mercy and life everlasting.”

2 Maccabees 12:45-46 teaches that praying for the dead.

2 Maccabees 12:45-46 Douay-Rheims Bible – 45 And because he considered that they who had fallen asleep with godliness, had great grace laid up for them. 46 It is therefore a holy and wholesome thought to pray for the dead, that they may be loosed from sins.

Sirach 3:30 teaches likewise that giving to the poor brings forgiveness for sins.

Sirach 3:30 CEV – Money given to the poor brings forgiveness for sins, just as water puts out a fire.

These teachings are in direct violation with the Old and New Testaments.

5.) The post-apostolic church never affirms deuterocanonical / apocryphal works. There is no sense in which a general church council in the first four centuries of Christian history endorsed the apocryphal books.

“. . . the early post-apostolic church was never in doubt as to the extent of the OT canon. There were, to be sure, critics of the traditional position, mainly those who wished to subtract from and not add to the canon, but these were considered heretics whose position on this as well as other matters was to be soundly repudiated.”
━━ Eugene H. Merrill, The Canonicity of the Old Testament in The World and the Word: An Introduction to the Old Testament (Nashville: B&H Academic, 2011), 100.

Merrill notes that in the Orthodox (Eastern) tradition:

“The earliest Eastern church fathers refused to include the apocryphal literature in the cannon. They recognized its value in some instances but denied its canonicity.”
━━ Eugene H. Merrill, The Canonicity of the Old Testament in The World and the Word: An Introduction to the Old Testament (Nashville: B&H Academic, 2011), 100.

Merrill’ ‘s comments on the Roman Catholic (Western) tradition are also helpful, and will be quoted at length:

“The question of the extent of the OT canon was greatly complicated by the fact that the Western church, for the most part, was an offspring of the Alexandrian ecclesiastical and canonical tradition by virtue of the Latin versions having been translated from the LXX and not the Hebrew Scriptures. The longer Alexandrian canon (the Hebrew 22 books plus 14 apocryphal books) was thus incorporated into the earliest Latin Bible, the so-called Itala, with apparently little or no dissent except for the omission of 3 and 4 Maccabees and the addition of 2 Esdras (= 4 Ezra).

In AD 385 Jerome undertook a new Latin version (the Vulgate) that was initially a revision of Itala and then a fresh translation of the Hebrew. Having come to recognize the intrinsic worth and authority of the Hebrew text, Jerome also felt compelled to limit his canon to the 22 books of the Jewish canon. He did not entirely repudiate certain apocryphal writings, however. In fact, he grudgingly approved at least an intermediate status for Judith, Tobit, Maccabees, Wisdom, and Sirach, and even allowed the Additions to Daniel and Additions to Esther to be added to his list though clearly as subcanonical works. Jerome’s willingness to countenance even part of the apocryphal literature paved the way for the inclusion of more of it in years to come. The principal manuscript of the Vulgate (Amiatinus, c. AD 700) contains all the books of Jerome plus others he had clearly rejected and claimed that all of them carried his sanction, This collection received its final stamp of approval at the Council of Trent (1546) and to this day is the canon followed by the Roman Catholic Church.

Other voices also contributed to the debate and must be given at least brief mention. The first of these is Melito of Sardis, who in the second century (c. 160) compiled a canon lacking Esther and all of the Apocrypha. Origen (c. 250) embraced all the Hebrew canon (including Esther) and also apparently the Epistle of Jeremiah, Susanna, Tobit, and Judith. Hilary of Poitiers (c. 350) followed Origen’s lead, but Rufinus (c. 400) agreed with Jerome that the apocryphal works in their entirety should be relegated to secondary status. Augustine (c. 400), however, brought his considerable prestige to bear and, against Jerome, he regarded Tobit, Judith, 1 and 2 Maccabees, Wisdom, and Sirach as fully canonical, though in his latest writings he gathered the apocryphal writings together and placed them at the end of the Jewish canon.”
━━ Eugene H. Merrill, The Canonicity of the Old Testament in The World and the Word: An Introduction to the Old Testament (Nashville: B&H Academic, 2011), 101. Bold added by me.

6.) Historian Flavius Josephus affirmed that the Jews possess 22 sacred books (the same 39 books as Protestants just grouped slightly differently), which means they rejected the deuterocanonical / apocryphal works:

“We have but twenty-two [books] containing the history of all time, books that are justly believed in; and of these, five are the books of Moses, which comprise the law and earliest traditions from the creation of mankind down to his death. From the death of Moses to the reign of Artaxerxes, King of Persia, the successor of Xerxes, the prophets who succeeded Moses wrote the history of the events that occurred in their own time, in thirteen books. The remaining four documents comprise hymns to God and practical precepts to men (William Whiston, trans., Flavius Josephus against Apion, Vol. I, in Josephus, Complete Works, Grand Rapids: Kregel, 1960, p. 8).”

7.) The deuterocanonical / apocryphal works do not attest to being Scripture.

It should be clear why the Protestant church rejects the deuterocanonical and apocryphal works. They should not be in the canon of scripture and are not inspired by God.

In the Leiden Synopsis of a Purer Theology the authors conclude:

“The reasons why we should consider none of these writings as sacred are: In the first place, that they were not produced by the Spirit of prophecy, since they were written after the time of Artaxerxes, in which no succession of prophets was found (Rom 16:26, Josephus, Against Appian, 2). Second, because they were not placed in the ark, as the tables of the Law were, or beside the ark, as the books of Moses were (Deut 31, Epiphanius, On Measures and Weights). Third, because they were not written or preserved in the Hebrew language, nor did the Jewish church, to whom the divine oracles had been entrusted, ever acknowledge them as such (Josephus, Against Appian 4). Fourth, because neither Christ, nor the apostles, nor the early Church acknowledges them as such, but they considered them not genuine (Amphilochius and Gregory of Nazianzus, both in Balsamon), and were admitted by the later Church with considerable variance and dispute, and then only as ecclesiastical (Synod of Carthage, 3; Augustine, On Christian Doctrine, Rufinus, On the Creeds, 5). Fifth, and finally, because they contain nonsensical, mainly fictitious things, and things that are not in harmony with the sacred writings which it would take too long to review here.”

Moving to the New Testament, there is general consensus and agreement between Protestants, Roman Catholics, and Orthodox regarding the New Testament books, so I won’t linger long on this point.

Köstenberger, Kellum, and Quarles are helpful here in reiterating the point that was made above regarding authoritative or ministerial recognition of the New Testament books:

“God, through the agency of the Holy Spirit and the instrumentality of the NT writers, generated Holy Scripture (a phenomenon called “inspiration”); and the church’s task was not the creation of the canon but merely the recognition of the Scriptures God had previously chosen to inspire. It follows that, if the church’s role is primarily passive in determining the Christian canon, then it is inspired Scripture, not the church, which is in the final position of authority.”
━━ Andreas J. Köstenberger, L. Scott Kellum, and Charles L. Quarles, The Lion and the Lamb, New Testament Essentials from The Cradle, the Cross, and the Crown (Nashville: B&H Academic, 2012), 3. Italics in the original.

Again, we must be clear that the church is not the active agent in creating what is inspired, God the Holy Spirit, has inspired those writings, and has guided His church to recognize what is inspired. The church is the passive receiver of the Word of God.

It is also important for us to note that the,

“. . .NT documents were recognized as authoritative, even Scripture, as early as the end of the first, or at least by the end of the second century of the Christian era. The four Gospels, the book of Acts, the letters of Paul, 1 Peter, and 1 John were universally recognized. With the exception of 3 John, the early church fathers cirted all NT books as Scripture. Toward the end of the second century, the major contours of the NT had clearly emerged, setting the framework for the subsequent final resolution of the canonical status of several remaining smaller or disputed books.”
━━ Andreas J. Köstenberger, L. Scott Kellum, and Charles L. Quarles, The Lion and the Lamb, New Testament Essentials from The Cradle, the Cross, and the Crown (Nashville: B&H Academic, 2012), 5.

This means that well before a council codified what would be considered “canon” there was already widespread adoption and agreement on what was considered New Testament Scripture.

Why was there a need to establish the canon of the New Testament, was it because the Church needed a council to determine what was authoritative? Norman L. Geisler and William E. Nix in their A General Introduction to the Bible book are helpful here:

“From the human point of view there were several stimuli for the collection and final canonization of inspired books.

Books were prophetic. The initial reason for collecting and preserving the inspired books was that they were prophetic. That is, since they were written by an apostle or prophet of God, they must be valuable, and if valuable, they should be preserved. This reasoning is apparent in apostolic times, by the collection and circulation of Paul’s epistles (cf. 2 Peter 3:15-16; Col. 4:16). The postapostolic period continued to reflect this high regard for the apostolic writings of the New Testament by their voluminous and authoritative quotations from those inspired books.

Demands of early church. Closely connected with the foregoing reason for preserving the inspired books were the theological and ethical demands of the early church. That is, in order to know which books should be read in the churches (cf. 1 Thess. 5:27 and 1 Tim. 4:13) and which books could be definitely applied to the theological and practical problems of the Christian church (cf. 2 Tim. 3:16-17), it became necessary to have a complete collection of the books that could provide the authoritative norm for faith and practice.

Heretical stimulus. On the negative side there was the heretical stimulus. At least as early as A.D. 140 the heretical Marcion accepted only limited sections of the full New Testament canon. Marcion’s heretical canon, consisting of only Luke’s gospel and ten of Paul’s epistles, pointed up clearly the need to collect a complete canon of New Testament Scriptures.

Missionary stimulus. On the positive side, there was the missionary stimulus. Christianity had spread rapidly to other countries, and there was the need to translate the Bible into those other languages (see chaps. 27-29). As early as the first half of the second century the Bible was translated into Syriac and Old Latin. But because the missionaries could not translate a Bible that did not exist, attention was necessarily drawn to the question of which books really belonged to the authoritative Christian canon.

Persecutions and politics. The final phase of full and general recognition of the whole canon of New Testament writings also involved a negative and political stimulus. The Diocletian persecutions of about A.D. 302/303-5 provided forceful motivation for the church to sort, sift, and settle on the New Testament Scriptures. For certainly the books they would risk their lives to preserve must have been considered sacred to them.”
━━ Norman L. Geisler and William E. Nix, A General Introduction to the Bible, rev. and exp. ed. (Chicago: Moody, 1986), 277-278.

Because there is widespread agreement on which books should be included in the canon and the Church recognizes what are considered inspired works from God, I won’t address the Ethiopian Orthodox position.

A Brief Case for the Protestant Canon

Thesis: The sixty-six books of the Protestant canon are the inspired Word of God because they were breathed out by God, received by the apostolic Church, providentially preserved throughout history, recognized by the universal Church, and bear the marks of divine inspiration. The Church did not create the canon but recognized the canon that God had already established through inspiration.

PILLAR 1: INSPIRATION DETERMINES CANONICITY

A book is canonical because God inspired it, not because a Church council recognized it. God’s inspiration must be the starting place based upon 2 Tim 3:16. As noted above: Whatever God inspires is Scripture. The biblical books were inspired by God, therefore the biblical books are Scripture.

PILLAR 2: SCRIPTURE WAS SCRIPTURE BEFORE ANY COUNCIL

Let’s again use the book of Romans as a case example. When was Romans determined to be Scripture? There are two options: (a) when Paul wrote it or (b) when the Church declared it. Protestantism argues that Romans became scripture through inspiration, not when the Church declared it to be so.

PILLAR 3: THE APOSTOLIC CHURCH ALREADY RECOGNIZED SCRIPTURE

The Apostolic and post-apostolic church had already recognized what was and what was not Scripture. Yes, there were some debates, but in general a proto-canon had already appeared before the 2nd century. The canon wasn’t discovered privately. This is an important point to make for us as Protestants. Roman Catholic and Othodox proponents have been spot on to point out that the universal body of Christ were involved in recognizing what was and what was not considered canonical. It wasn’t individuals who put together a list, it was the body of Christ as a collective entity that recognized what was Scripture. The error is saying that Rome or Orthodoxy gave us the Bible, or the idea that every individual was forced to figure it out. God providentially led His Church to recognize what was inspired.

PILLAR 4: GOD’S PROVIDENTIAL HAND IN PRESERVATION

As Protestants we believe that God promised to preserve His Word (cf. Psalm 12, Isaiah 40, Matthew 5, Matthew 24, 1 Peter 1, etc.). If God inspired His Word, He is capable of persevering it. Because God is sovereign over history, then He is also sovereign over the preservation of His revelation. The canon is not a product of ecclesiastical invention but of divine providence.

PILLAR 5: THE MARKS OF CANONICITY

As argued for above, these are the marks of canonicity.

Old Testament Criteria for Recognition:

1.) Prophetic Authority
2.) Agreed with Previous Divine Revelation
3.) Reception by the Covenant Community
4.) Internal Marks of Divine Authority
5.) New Testament use of the Old Testament

New Testament Criteria for Recognition:

1.) Apostolic Authority
2.) Agreement with Apostolic Doctrine
3.) Agreement with Previous Revelation
4.) Reception by the Covenant Community
5.) Universal Reception
6.) Internal Marks of Divine Authority

Conclusion

The question, “How do Protestants know they have the correct canon?” is often presented as though it were a uniquely Protestant problem. It is not. Every Christian tradition must answer two questions: Which books belong in the canon? and By what authority do we know they belong there? The real difference here is not whether the Church recognized the canon—we all affirm that it did—but in what role the Church played in that recognition.

The Protestant position is clear. A book is not Scripture because the Church recognized it; rather the Church recognized it because God had already made it Scripture through divine inspiration. Inspiration must determine what is considered canonical. Recognition acknowledges canonicity. These must never be confused.

As demonstrated through redemptive history (Old and New Testaments), this has been God’s ordinary pattern. The Old Testament was received by Israel because it came through God’s prophets. The New Testament was received by the Church because it came through Christ’s Apostles. In both cases, God’s covenant people recognized His Word because it bore the marks of divine inspiration, agreed with previous revelation, and was providentially preserved and received by the covenant community. Councils did not create this reality, neither in the Old nor New Testament period.

This is why Protestants reject the notion that an infallible ecclesiastical decree or a Holy Tradition which is necessary to establish the canon. These views mistake recognition for creation. The Church identifies what books are inspired because their inspiration is stamp by God with authority. The Church’s authority is ministerial, not magisterial over the Word.

As I have tried to show above, an appeal to “the Church” doesn’t actually resolve the canon question. Roman Catholicism and Orthodox traditions claim apostolic continuity and ecclesiastical authority, yet they do not have identical canons. The former claims infallibility, the latter claims Holy Tradition. It is simple to push back on either side and claim “Which Church?” It is important to note that when an apologist asks these types of loaded questions, it moves the discussion from canonicity to ecclesiology.

Ultimately, the Protestant confidence in the canon rests not upon Luther, Calvin, The Westminster Confession of Faith, or any fourth-century council, but upon the faithfulness of God. The God who inspired His Word also preserved it, and through His providence led His covenant people to recognize His voice in the Scriptures, both Old and New. As Jesus declared, “My sheep hear my voice” (John 10:27). The Church does not stand over Scripture as its judge; it stands under Scripture as its servant.
