How did we get the Bible? The formation of the Christian Canon.
The Christian Bible did not emerge as a single book dropped from heaven in completed form. Rather, it developed over centuries through worship, oral tradition, inspired writing, community discernment, and the guidance of the Church. The word canon comes from a Greek term meaning “rule,” “measure,” or “standard.” In Christian faith, the canon refers to those writings recognized as divinely inspired and authoritative for belief, teaching, and practice. The process of forming the Bible reflects both human history and the conviction that God was actively guiding His people in preserving His revelation.
The Formation of the Old Testament
The first portion of the Christian Bible is what Christians call the Old Testament. These books originated within the life of ancient Israel and were written over many centuries. Their earliest traditions were passed along orally before being written and preserved.
The foundational books—Genesis through Deuteronomy—were associated with Moses and became central to Jewish identity and worship. Alongside the Law came historical writings, wisdom literature, poetry, and prophetic books. Over time, these writings were read publicly in worship and accepted as sacred.
By the time of Jesus, Jewish communities largely recognized three categories of sacred writings: the Law, the Prophets, and the Writings. Jesus Himself referenced these categories, suggesting a recognized body of Scripture already existed. Yet there remained discussion among Jewish communities concerning certain books.
An important development occurred around the third and second centuries BC when Hebrew Scriptures were translated into Greek in Alexandria, Egypt. This translation became known as the Septuagint. Because Greek had become the common language of much of the Mediterranean world, the Septuagint was widely used by Jews outside Palestine and eventually by early Christians.
The Septuagint contained several books not included in the later Hebrew Bible. These books—including Tobit, Judith, Wisdom, and others—came to be called the Apocrypha or Deuterocanonical books. Different Christian traditions later viewed these writings differently. Roman Catholic and Orthodox churches included many of them in their canon, while most Protestant traditions did not.
The New Testament Begins
The New Testament emerged from the life, death, and resurrection of Jesus Christ and the witness of His earliest followers. Unlike the Old Testament, these writings appeared over a relatively short period, mostly between AD 50 and AD 100.
The earliest Christian message was transmitted orally. The apostles preached, taught, and shared memories of Jesus before anything was written down. As Christianity spread and eyewitnesses aged or died, the need for written records became more urgent.
The first New Testament writings were likely Paul’s letters. Addressed to churches and individuals, they provided theological instruction, correction, encouragement, and practical guidance. Churches copied these letters and circulated them among believers.
Soon afterward came the four Gospels: Matthew, Mark, Luke, and John. Each offered a unique perspective on Jesus while preserving the central witness to His ministry, death, and resurrection. Additional writings followed, including Acts, general letters, and Revelation.
Not every early Christian writing gained equal authority. Many texts circulated in the early Church. Some were orthodox and useful for devotion but were not considered Scripture. Others contained teachings inconsistent with apostolic faith.
This created an important question: Which books truly belonged?
Criteria for Recognizing the Canon
The Church did not arbitrarily create Scripture. Rather, Christian communities gradually recognized books already functioning as authoritative. Several principles guided this process.
Apostolic Connection
A writing needed a clear relationship to the apostles or their close associates. Because the apostles had personally witnessed Christ or were directly commissioned by Him, their testimony carried special authority.
For example:
Matthew and John were apostles.
Mark was associated with Peter.
Luke traveled with Paul.
Apostolic connection served as a safeguard for preserving authentic teaching.
Orthodoxy
Books needed to agree with the Church’s received understanding of the gospel. Writings promoting teachings contrary to apostolic faith were rejected.
This became particularly important in responding to movements such as Gnosticism, which often presented radically different views of Jesus, creation, and salvation.
Widespread Use
Christian communities across regions consistently used certain writings in worship and teaching. Books accepted broadly across the Church gained increasing recognition.
The question was not merely, “Do we like this writing?” but rather, “Has the Church consistently recognized God's voice here?”
Challenges and Debates
Some books achieved immediate acceptance. The four Gospels and many Pauline letters gained early and broad recognition.
Others generated discussion.
Books such as Hebrews, James, 2 Peter, Jude, and Revelation were debated in some regions because of uncertainty concerning authorship or interpretation.
Likewise, certain writings highly valued by early Christians were eventually excluded from the canon. Among them were:
The Shepherd of Hermas
The Didache
The Epistle of Barnabas
First Clement
These are all early Christian writings, though they didn’t make it into the final biblical canon. The Shepherd of Hermas is an early second-century work filled with visions and parables, emphasizing repentance. The Didache, or “Teaching of the Twelve Apostles,” is a first-century manual of Christian ethics, practices, and church order. The Epistle of Barnabas is an early Christian letter that interprets the Old Testament in light of Christ, sometimes allegorically. First Clement is a letter from the church in Rome to Corinth, likely written in the late first century, urging unity and order. All of them were respected and influential in early Christian communities.
These books often served devotional or instructional purposes but lacked sufficient apostolic authority or universal recognition.
Early Church Recognition
The second through fourth centuries proved decisive.
Around AD 170, an early document known as the Muratorian Fragment listed many books already accepted by Christians.
Early Church leaders such as Irenaeus strongly defended the authority of the four Gospels and apostolic writings.
Later scholars such as Origen and Eusebius categorized books as accepted, disputed, or rejected.
A major milestone occurred in AD 367 when Athanasius issued an Easter letter listing the exact twenty-seven books now found in the New Testament.
Church councils later affirmed this recognition, including the Council of Hippo and the Council of Carthage.
Importantly, these councils did not create Scripture. Christians generally understand them as recognizing and affirming what the Church had already received and used.
Theological Meaning of the Canon
For Christians, the formation of the canon represents more than historical development. It reflects the conviction that God worked through imperfect human communities to preserve divine revelation.
The process was lengthy and occasionally disputed, yet Christians believe the Holy Spirit guided the Church toward faithful recognition of inspired writings.
This understanding avoids two extremes: the notion that Scripture simply appeared without historical development and the idea that Church leaders merely invented the Bible according to personal preference.
Instead, the Christian story of canon formation is one of discernment. Communities prayed, worshiped, taught, debated, and listened together for the voice of God.
The resulting collection of books became Christianity’s foundational authority—a library of writings bearing witness to God's redemptive work from creation to Christ and ultimately to the hope of new creation.
The Bible, therefore, is not merely a collection of ancient texts. For Christian faith, it is the story of God’s relationship with humanity, recognized across centuries as sacred Scripture and preserved for the life of the Church to come.
