Most believers who pick up a Bible assume every Christian tradition uses the same collection of books. That assumption breaks down quickly when you encounter the Orthodox Bible, which contains significantly more books than most Protestant editions.
The question of how many books the Orthodox Bible contains matters because it shapes how millions of Christians understand Scripture, worship, and the full scope of God’s revelation to His people.
How Many Books Are in the Orthodox Bible?
The Orthodox Bible contains 78 books in total: the 39 books of the Old Testament, the 27 books of the New Testament, and 12 additional books known as the Deuterocanonical books or Anagignoskomena. Some Orthodox traditions include even more texts, such as Psalm 151, 3 Maccabees, and 4 Maccabees, bringing the count higher depending on the specific church tradition.
The Complete Count Explained
The 78-book total represents the most common Orthodox canon, though the exact number varies slightly between different Orthodox churches. The Greek Orthodox Church, Russian Orthodox Church, and other Eastern Orthodox bodies generally agree on the core collection but may differ on a handful of additional writings.
These extra books appear between the Old and New Testaments in most Orthodox Bible editions. They bridge the silent years between Malachi and Matthew, covering the intertestamental period when God’s people faced persecution, preservation, and spiritual testing under foreign powers.
Why the Difference Exists
The variation in biblical canons traces back to different ancient manuscript traditions. Orthodox Christianity followed the Septuagint, the Greek translation of the Hebrew Scriptures used widely in the early church and quoted frequently by New Testament authors.
Protestant Christianity later adopted the Hebrew Bible canon, which excluded the Deuterocanonical books. This decision came during the Reformation when scholars returned to Hebrew sources and questioned books not found in the Jewish canonical lists.
What Are the Deuterocanonical Books?
The Deuterocanonical books are the additional writings that Orthodox and Catholic Christians include in their Old Testament canon. The term means “second canon,” not because these books hold less authority, but because their canonical status was debated more extensively in church history than the protocanonical books everyone accepted.
The Twelve Core Deuterocanonical Books
Orthodox Bibles typically include these additional books:
- Tobit – A story of faithfulness, prayer, and God’s deliverance through hardship
- Judith – An account of courage and divine intervention during foreign invasion
- Wisdom of Solomon – Poetic reflections on wisdom, righteousness, and the nature of God
- Sirach (Ecclesiasticus) – Practical wisdom for daily living and fearing the Lord
- Baruch – Prophetic reflections during the Babylonian exile
- Letter of Jeremiah – A warning against idolatry (sometimes included as Baruch 6)
- 1 Maccabees – Historical account of Jewish resistance and the Maccabean revolt
- 2 Maccabees – Theological reflection on the same period with emphasis on martyrdom
- Additions to Esther – Extended passages that include prayers and explicit references to God
- Additions to Daniel – Three sections: the Prayer of Azariah, the Song of the Three Holy Children, Susanna, and Bel and the Dragon
Additional Books in Some Orthodox Traditions
Certain Orthodox churches include even more writings. The Greek Orthodox Church adds Psalm 151, 3 Maccabees, and 4 Maccabees (the latter sometimes placed in an appendix).
The Slavonic tradition, followed by Russian and other Slavic Orthodox churches, includes 1 and 2 Esdras. These variations reflect the different manuscript traditions preserved in various Orthodox communities over centuries.
Why Do Orthodox Christians Include These Books?
Orthodox Christianity didn’t add these books to Scripture at some later date. The Orthodox Church simply maintained the broader collection it received from the beginning, rooted in the Septuagint that Jesus and the apostles knew and used.
The Septuagint Connection
The Septuagint served as the Bible of the early church. When Paul quoted Old Testament passages in his letters, he often used the Septuagint translation rather than translating directly from Hebrew.
The New Testament contains numerous allusions to Deuterocanonical books, though not always direct quotations. Hebrews 11:35 references the martyrdom accounts found in 2 Maccabees 7, and the armor of God passage in Ephesians 6 echoes language from Wisdom of Solomon 5:17-20.
Historical Church Practice
Early church councils and fathers treated these books as Scripture. The Council of Carthage in 397 AD confirmed a biblical canon that included the Deuterocanonical books, and church leaders like Augustine cited them as authoritative.
Orthodox Christianity sees no reason to remove what the church has always accepted. The burden of proof rests on those who would subtract from the received tradition, not on those who maintain it.
Spiritual Value and Teaching
These books contain genuine spiritual wealth. Sirach offers profound wisdom about friendship, humility, and the fear of the Lord that resonates with Proverbs and Ecclesiastes.
The Maccabees record faithful endurance under persecution that still encourages believers facing opposition today. God doesn’t always deliver His people from suffering immediately, but He walks with them through it and vindicates them in His timing.
What About Protestant Bibles?
Protestant Bibles contain 66 books: 39 in the Old Testament and 27 in the New Testament. The Deuterocanonical books don’t appear in most Protestant editions, though earlier Protestant Bibles often included them in a separate section between the testaments.
The Reformation Decision
Protestant reformers returned to the Hebrew canon partly because they wanted to use the same Old Testament boundaries as first-century Judaism. They also noted that some Deuterocanonical books contained theological statements that conflicted with Reformation doctrine, particularly regarding prayers for the dead in 2 Maccabees 12:45.
Martin Luther didn’t remove these books entirely from his German Bible—he placed them in a separate section labeled “Apocrypha,” meaning “hidden” books useful for reading but not equal to Scripture. Later Protestant publishers eventually dropped them altogether to reduce printing costs and reflect their diminished status.
Different Doesn’t Mean Wrong
The canon debate need not divide Christians who agree on central gospel truths. Whether you read 66, 73, or 78 books, all Christians affirm the same New Testament and the same core Old Testament.
The Deuterocanonical books occupy a middle ground—not fabricated texts, but genuine ancient Jewish writings whose canonical status Christians have evaluated differently. Protestant believers can still benefit from reading them as historical and devotional literature even if they don’t regard them as Scripture.
Does the Number of Books Change the Gospel?
No. The gospel remains the same regardless of which canon you follow: humanity stands condemned by sin, unable to save itself, and God provided redemption through Jesus Christ who died for sinners and rose from the dead.
Core Doctrines Remain Intact
Every essential Christian doctrine appears clearly in the 66 books all traditions share. The deity of Christ, the Trinity, salvation by grace through faith, the resurrection, and the return of Christ all emerge from the commonly accepted Scriptures.
The Deuterocanonical books enrich understanding of Second Temple Judaism and provide additional examples of faith and wisdom. They don’t introduce doctrines absent from the rest of Scripture, but they do emphasize certain themes like prayers for the departed and almsgiving that some traditions rejected.
Unity in Essentials
Christians who use different biblical canons still worship the same God and confess the same Savior. The differences matter for understanding church tradition and interpretive authority, but they don’t undermine shared faith in Christ.
Scripture itself reveals God’s character, His redemptive plan, and His expectations for His people. Whether you encounter that revelation through 66 or 78 books, the call to love God with all your heart and trust Jesus as Lord remains identical.
Should You Read the Deuterocanonical Books?
Even if you worship in a tradition that doesn’t consider these books Scripture, reading them offers genuine value. They illuminate the historical and spiritual context of the New Testament in ways that deepen understanding of Jesus and the apostles.
Historical Context for the New Testament
The Maccabean period shaped Jewish expectations of the Messiah. When Jesus entered Jerusalem and people laid palm branches before Him, they echoed the celebration described in 1 Maccabees 13:51 when Simon Maccabeus entered Jerusalem victorious.
Understanding the struggles, hopes, and theological developments of the intertestamental period helps explain why Jews expected a conquering military Messiah and struggled to accept a suffering servant. The Deuterocanonical books fill in crucial historical gaps.
Wisdom and Devotional Richness
Sirach contains some of the most beautiful wisdom literature in existence. Its teachings on humility, generosity, and the proper fear of God align perfectly with the rest of Scripture’s wisdom tradition.
Tobit offers a moving story of faithfulness during exile and answered prayer that encourages believers today. Reading it won’t lead you astray theologically—it points toward the same faithful God revealed throughout Scripture.
Discernment Still Applies
Approach these books the same way you approach any spiritual reading outside Scripture: with discernment, comparing everything to clear biblical teaching. Let Scripture interpret Scripture, using the clearer passages all Christians accept to evaluate themes in disputed texts.
You don’t have to settle the canonical question personally to benefit from reading these ancient writings. Many Protestant scholars and pastors read the Deuterocanonical books regularly for historical insight and spiritual enrichment without accepting them as Scripture.
Living Faithfully with Canon Differences
The canon question reminds us that Christians have wrestled with boundaries and authority throughout church history. Rather than pretending these differences don’t exist, acknowledge them honestly while maintaining unity on gospel essentials.
Focus on What Unites
Orthodox, Catholic, and Protestant believers share far more than divides us. All confess Jesus Christ as Lord, affirm His death and resurrection, and trust in God’s grace for salvation.
The books we have in common provide more than enough truth to know God, understand His will, and live faithfully. Canon differences matter, but they shouldn’t prevent partnership in gospel work or mutual love as brothers and sisters in Christ.
Respect Different Traditions
Orthodox Christians maintain their canon as a faithful preservation of ancient church practice. Protestant Christians maintain theirs as a return to the Hebrew sources and a concern for clearer canonical boundaries.
Both motivations reflect legitimate concerns about authority and faithfulness. You can hold your position firmly while respecting believers who reached different conclusions through sincere engagement with history and Scripture.
Study Scripture Regardless of Count
The real problem isn’t disagreement about a dozen books—it’s biblical illiteracy regardless of which Bible sits on the shelf. Believers who never open their Bibles lose far more than any canonical debate could cost.
Read the Scriptures you have. Study them deeply, meditate on them daily, and let them transform how you think and live. God speaks powerfully through His Word when you actually engage it rather than merely discussing which version has proper credentials.
The Heart of the Matter
The Orthodox Bible contains 78 books because Orthodox Christianity maintained the broader Septuagint-based canon used by the early church. Protestant Bibles contain 66 books because the Reformation returned to the narrower Hebrew canon.
Both traditions preserve genuine Scripture, and both provide more than enough divine revelation to know God and follow Christ faithfully. The differences reflect historical and theological decisions, not errors or conspiracies.
What matters most isn’t winning canon debates but obeying what Scripture clearly teaches. Love God wholeheartedly, love your neighbor as yourself, trust Jesus for salvation, and walk in holiness—these commands appear unmistakably in every Christian Bible.
Let the Orthodox faithful treasure their 78 books as their received tradition. Let Protestant believers hold to their 66 books as their conviction. And let all who name Christ as Lord unite around the gospel that saves and the Spirit who sanctifies.
The number of books in your Bible matters less than whether you’re actually reading, believing, and obeying the one you have. God’s Word accomplishes His purposes regardless of canonical boundaries when believers receive it with humble, obedient hearts.
If you found this exploration of biblical canons helpful, you might want to explore related topics. Understanding how many books different Christian traditions include helps clarify why variations exist. Learning what the Jewish Bible is called and how it differs from Christian Old Testaments provides important context for understanding Scripture’s development and transmission across faith communities.
