What books were excluded from the Bible?
What about books that were left out of the Bible?

Overview of the Question

When people inquire about “books that were left out of the Bible,” they are often referring to writings—ancient or otherwise—that did not make it into the recognized scriptural canon. This topic has generated conversations about hidden gospels, apocryphal texts, and alleged “lost” biblical writings. Below is a thorough exploration of how the canon was formed, what criteria were used, and why certain books were excluded from Scripture.


1. Historical Context of the Biblical Canon

From the earliest days, God’s people upheld certain texts as divinely inspired. In the Hebrew tradition, the Law, the Prophets, and the Writings were already firmly recognized long before the time of Jesus. In the New Testament period, Jesus and the apostles frequently quoted books from the Hebrew Scriptures (e.g., Luke 24:44 states, “He said to them, ‘These are My words that I spoke to you while I was still with you: Everything must be fulfilled that is written about Me in the Law of Moses, the Prophets, and the Psalms.’”).

The New Testament writings began circulation early in the first century AD, recognized by Christian congregations as authentic apostolic testimony. The canonical Gospels (Matthew, Mark, Luke, and John) received wide acceptance, as did Paul’s letters. By the late second century, major portions of what we now know as the New Testament were cited in documents like the Muratorian Fragment, providing evidence that these works were esteemed as authoritative Scripture.


2. Criteria for Canonical Recognition

Early church leaders used specific criteria to identify which books were inspired. These included:

- Apostolic Origin: The text needed to be linked directly to an apostle or a close companion of an apostle.

- Widespread Usage: A book was recognized throughout diverse Christian communities, signifying its importance and authenticity.

- Orthodox Teaching: The message in the book had to align with established truths received from Jesus and the eyewitness apostles.

- Historical Connection: An unbroken tradition of faithful believers had consistently affirmed the text’s authority.

2 Timothy 3:16–17 underscores the necessary qualification of inspired Scripture: “All Scripture is God-breathed and is useful for instruction, for conviction, for correction, and for training in righteousness, so that the man of God may be complete, fully equipped for every good work.”


3. Apocryphal and Deuterocanonical Writings

The term “Apocrypha” traditionally refers to a collection of Jewish texts written in the intertestamental period (roughly 400 BC to the early first century AD). Some Christian communities, notably within certain historical and modern denominations, include these as “deuterocanonical.” Over time, others recognized them as instructive yet non-canonical because they did not meet the same criteria (especially regarding apostolic origin).

Although the Apocrypha can provide historical and cultural context, they often contain doctrinal discrepancies when measured against the rest of Scripture. Their use in the early church varied. By the time of the Reformation, many communities firmly separated these texts from the Old Testament canon recognized by Jesus and the apostles.


4. Gnostic and Pseudepigraphal Texts

During the second to fourth centuries AD, various sects produced alternate “gospels,” such as the “Gospel of Thomas,” the “Gospel of Judas,” and other writings bearing apostolic names. Scholars frequently classify these as “Gnostic Gospels.” These works generally present a worldview that conflicts with core biblical doctrines—especially those concerning Christ’s physical resurrection, the nature of salvation, and the identity of God.

For instance, many Gnostic texts teach secret knowledge as a means of salvation, in contrast to Scripture’s emphasis on Christ’s atoning death and physical resurrection (Romans 10:9: “If you confess with your mouth, ‘Jesus is Lord,’ and believe in your heart that God raised Him from the dead, you will be saved”). The early church councils—such as those at Hippo Regius (AD 393) and Carthage (AD 397)—formally recognized which books were true, apostolic Scripture and rejected those that were inconsistent with the apostles’ teaching.


5. Archaeological Insights

Substantial archaeological finds affirm the historicity and accuracy of canonical Scripture, providing indirect evidence for its reliability and authenticity. For example:

- Dead Sea Scrolls (mid-20th-century discovery): These scrolls, including the Great Isaiah Scroll, confirm that the Old Testament texts were preserved with remarkable fidelity over centuries.

- Nag Hammadi Library (discovered 1945): This discovery contained many Gnostic writings. Church leaders in the centuries following the apostles swiftly recognized that these texts contradicted key Christian beliefs about Jesus’ deity and resurrection.

- Geological and Historical Corroborations: Excavations of places like Jericho, the Pool of Bethesda (John 5:2), and other biblical sites reinforce the authenticity of the Scriptures by affirming the real geographical and historical contexts described in both Old and New Testaments.


6. Evidence from Early Church Fathers

Leaders such as Clement of Rome (late first century), Ignatius of Antioch (early second century), and Irenaeus (late second century) quoted extensively from books we now recognize as canonical. These references demonstrate that the earliest Christians already regarded these writings as binding and divine in origin.

For instance, Irenaeus in his work “Against Heresies” often quoted four Gospels—Matthew, Mark, Luke, John—while dismissing alternate, non-apostolic versions as unreliable. This widespread acceptance allowed the church to form a unified consensus regarding the inspired books.


7. Consistency and Transmission of Scripture

The textual transmission of both the Old and New Testaments is more thoroughly documented than any other ancient literary work. Ancient manuscripts—papyri, codices like Vaticanus and Sinaiticus—show consistent doctrinal content. Even where scribal variants appear, they rarely affect the key messages of the faith, and these differences have been transparently cataloged by modern scholars.

2 Peter 1:21 affirms the divine oversight in the recording of Scripture: “For no prophecy was ever brought forth by the will of man, but men spoke from God as they were carried along by the Holy Spirit.” This testimony is supported by the mountain of manuscript evidence demonstrating the overall purity in the copying process.


8. The Value of Non-Canonical Works

While the so-called “left-out books” do not hold the status of divine Scripture, some of them can offer helpful insight into the historical events, cultural traditions, or religious ideas that circulated in the ancient world. Researchers study these documents to understand how various groups approached spirituality, philosophy, and daily life.

Nevertheless, these writings do not form the doctrinal core of the Christian faith, nor do they align seamlessly with the overall witness of Old and New Testament Scriptures. As such, they should be read discerningly, measuring any spiritual claims against biblical revelation.


9. Conclusion: The Sufficiency of Scripture

The recognized canon—both Old and New Testaments—provides a unified message of God’s ongoing plan of redemption. The excluded writings, whether apocryphal, Gnostic, or merely historical, were set aside after rigorous examination.

Scripture itself declares its completeness and reliability. Revelation 22:18–19 warns against adding to or subtracting from God's Word: “I testify to everyone who hears the words of prophecy in this book: If anyone adds to them, God will add to him the plagues described in this book. And if anyone takes away from the words of this book of prophecy, God will take away his share in the Tree of Life and in the Holy City, which are described in this book.”

Today, the 66 books of the Bible stand as the authoritative, fully inspired foundation of faith and practice. This canon, confirmed by historical, manuscript, and doctrinal consistency, continues to hold its unique position as the Word of God—a record of the Creator’s work in history and His gracious offer of salvation through Jesus Christ.
