The Bible contains 66 books in most Protestant editions — but 73 in Catholic and 76 or more in Orthodox traditions. That's not a typo or a mistake. It reflects centuries of careful discernment about which texts belong in the Bible. Those books span roughly 1,500 years of writing, three continents, and two main languages (Hebrew and Greek). They include everything from poetry and prophecy to letters and apocalyptic visions. If you've ever felt overwhelmed by the sheer scope of it, you're not alone.

How Many Books Are in the Bible?
The exact count depends on which Christian tradition you're asking — and that's a legitimate, important distinction. Protestant Bibles contain 66 books: 39 in the Old Testament and 27 in the New Testament. Catholic Bibles contain 73 books, including 7 additional texts called the deuterocanonical books (more on those below). Eastern Orthodox Bibles typically include 76 or more books, though the precise count varies by regional church — the Ethiopian Orthodox Bible, for instance, contains 81 books, the largest Christian biblical canon in the world (Ethiopian Orthodox Tewahedo Church).
Citation capsule: Protestant Bibles contain 66 books, Catholic Bibles 73, and Eastern Orthodox Bibles 76 or more. These differences trace to decisions made during the Reformation (16th century) and earlier councils, particularly the Council of Trent (1546), which formally defined the Catholic canon. All traditions share the same 27 New Testament books without dispute.
Despite these differences, every Christian tradition agrees completely on the 27 books of the New Testament. The gap is entirely in the Old Testament, specifically over which texts were accepted into the Jewish biblical canon (the Hebrew Bible) before the New Testament was written.

The Old Testament — What's Inside
The Old Testament (called the Hebrew Bible or Tanakh in Jewish tradition) contains 39 books in Protestant editions. These books were written primarily in Hebrew, with portions in Aramaic. They cover the history of ancient Israel, God's covenant with his people, poetry, wisdom literature, and the messages of the prophets.
Citation capsule: The Old Testament contains 39 books (Protestant), 929 chapters, and roughly 23,145 verses (Britannica). It spans from the creation account in Genesis to the post-exilic prophets. Its books were written between approximately 900 BCE and 400 BCE, though they record events and oral traditions reaching back much further.
The 39 Old Testament books divide into four main sections:
1. The Law (Torah / Pentateuch) — 5 Books
Genesis, Exodus, Leviticus, Numbers, Deuteronomy.
These five books form the foundation of the entire Bible. They tell the story of creation, the fall, Noah, Abraham, Moses, and the giving of God's Law at Sinai. "In the beginning God created the heavens and the earth" (Genesis 1:1, NIV) is where every tradition begins.
2. History — 12 Books
Joshua, Judges, Ruth, 1 & 2 Samuel, 1 & 2 Kings, 1 & 2 Chronicles, Ezra, Nehemiah, Esther.
These books trace Israel's story from the conquest of Canaan through the monarchy (Saul, David, Solomon), the divided kingdom, the exile in Babylon, and the return to Jerusalem.
3. Poetry and Wisdom — 5 Books
Job, Psalms, Proverbs, Ecclesiastes, Song of Solomon.
The Psalms alone contain 150 individual poems covering praise, lament, confession, and trust. Proverbs offers practical wisdom. Job wrestles with suffering. These books speak directly to everyday human experience.
4. Prophets — 17 Books (Major and Minor)
Major Prophets (5): Isaiah, Jeremiah, Lamentations, Ezekiel, Daniel. Minor Prophets (12): Hosea through Malachi.
The terms "major" and "minor" refer to the length of the books, not their importance. The Minor Prophets are sometimes counted as one book (the "Book of the Twelve") in Jewish tradition.
The New Testament — What's Inside
The New Testament contains 27 books — and this is one point where all Christian traditions fully agree. These books were written in Greek, mostly in the first century CE, and center on the life, death, and resurrection of Jesus of Nazareth and the early church that formed after him.
Citation capsule: The New Testament's 27 books contain 260 chapters and approximately 7,957 verses (Oxford Biblical Studies). They were written between roughly 50 CE and 100 CE. The four Gospels, Acts, 21 Epistles, and Revelation form four distinct literary groupings, each serving a different purpose for readers.
The New Testament divides into four sections:
1. The Gospels — 4 Books
Matthew, Mark, Luke, John.
The word "gospel" means "good news." Each book tells the story of Jesus from a different angle. Matthew, Mark, and Luke share much of the same material and are called the Synoptic Gospels (from the Greek synoptikós, meaning "seen together"). John is distinct, focusing on theology and identity. "In the beginning was the Word" (John 1:1, NIV) opens John's account with cosmic scope.
2. Acts of the Apostles — 1 Book
Acts tells the story of the early church after Jesus's resurrection — Pentecost, the spread of the gospel from Jerusalem to Rome, and the missionary journeys of Paul. It's the essential bridge between the Gospels and the Letters.
3. The Epistles (Letters) — 21 Books
Paul wrote 13 of these letters (Romans through Philemon). Seven others (Hebrews through Jude) come from various authors and are often called the General Epistles. These letters addressed real communities facing real problems — theological disputes, moral questions, persecution, and practical church life.
4. Revelation — 1 Book
Also called the Apocalypse (from the Greek apokalypsis, meaning "unveiling"), Revelation is the New Testament's prophetic vision of the end of history and the renewal of all things. It was written in a symbolic literary style called apocalyptic literature (writing that uses vivid imagery to convey hope during persecution).
The Deuterocanonical Books (Apocrypha)
The deuterocanonical books — from the Greek meaning "belonging to the second canon" — are texts that appear in Catholic and Orthodox Bibles but not in Protestant ones. You may also hear them called the Apocrypha (from the Greek for "hidden things"), though that term is used differently across traditions.
Citation capsule: The seven deuterocanonical books in the Catholic Bible are Tobit, Judith, 1 Maccabees, 2 Maccabees, Wisdom of Solomon, Sirach (also called Ecclesiasticus), and Baruch. They appear in the Septuagint (the Greek Old Testament used by early Christians) but not in the Hebrew Bible finalized by Jewish scholars around 100 CE.
Catholic tradition accepted these books formally at the Council of Trent (1546), partly in response to the Protestant Reformation. Orthodox traditions include these seven plus additional texts like 1 Esdras, 3 Maccabees, and the Prayer of Manasseh. Protestant tradition, following Martin Luther and reformers' preference for the Hebrew canon, placed them in a separate section or omitted them altogether.
These books contain valuable history, prayer, and wisdom. 1 Maccabees, for instance, is the primary historical source for events between the Old and New Testaments. Whether your tradition includes them or not, knowing they exist helps you understand why Catholic and Protestant Bibles look different on a bookshelf.
How Are the Books Organized?
The Bible isn't arranged in chronological order. It's arranged by genre and literary type. Think of it less like a single novel read front-to-back and more like a library of different kinds of books, all telling one connected story.
Citation capsule: Biblical scholars identify at least six major literary genres across the books of the Bible: narrative/history, poetry, wisdom literature, prophecy, gospel, and epistle. Understanding which genre you're reading is essential for interpretation — a poem (like Psalms) operates differently from a legal text (like Leviticus) or a personal letter (like Philemon).
The main genres you'll encounter:
- Narrative: Stories of real people and events (Genesis, Acts, the Gospels)
- Law: Commands and covenant terms (Leviticus, Deuteronomy)
- Poetry: Emotional, lyrical expression (Psalms, Song of Solomon)
- Wisdom: Practical and philosophical reflection (Proverbs, Job, Ecclesiastes)
- Prophecy: Messages calling for repentance and pointing to God's future action (Isaiah, Revelation)
- Epistle: Letters addressing specific communities (Romans, Corinthians, Galatians)
If you use Bible Expert's side-by-side translation comparison, you'll notice that genre affects how different translators make choices — especially in poetry, where word-for-word and meaning-based translations can look quite different.
Where Should You Start Reading?
This is the most common question new readers ask — and the answer depends on what you're looking for. Here's what most experienced Bible teachers recommend:
If you want to understand who Jesus is: Start with the Gospel of John. It's the most theological of the four Gospels, but it's also written clearly for people who have no background. "For God so loved the world that he gave his one and only Son" (John 3:16, NIV) is one of the most cited verses in the Bible for good reason.
If you want to connect emotionally: Start with Psalms. These 150 poems cover grief, joy, anger, trust, doubt, and praise. You'll recognize your own feelings in them almost immediately. Psalm 23 — "The Lord is my shepherd, I lack nothing" (Psalm 23:1, NIV) — remains one of the most beloved passages across all traditions.
If you want the big story: Start with Genesis and follow the narrative through to the end of Acts. That four-book journey (Genesis → Exodus → the Gospels → Acts) gives you the essential arc of the biblical story.
If you're returning to faith after a gap: Start with the Gospel of Mark. It's the shortest Gospel (16 chapters), written with fast-paced urgency. You can read it in a single sitting.

What are the deuterocanonical books?
Deuterocanonical books are texts Catholics and Orthodox Christians include in their Old Testament that Protestants generally exclude. The 7 Catholic deuterocanonicals are Tobit, Judith, 1 and 2 Maccabees, Wisdom of Solomon, Sirach, and Baruch. They appear in the Septuagint (Greek Old Testament) but not in the Hebrew canon finalized around 100 CE.
What is the best book of the Bible to read first?
Most Bible teachers recommend starting with the Gospel of John. It tells the life of Jesus in clear language and directly answers "Who is Jesus?" Psalms is an excellent second choice — its 150 poems connect emotionally with readers from any background. Genesis works well for those who want to start at the very beginning of the story.
Are the books of the Bible in chronological order?
No. The books are organized by genre, not timeline. Law comes before History, Poetry sits in the middle of the Old Testament, and the Prophets come last — even though many prophets lived during the period covered by the History books. Bible apps like Bible Expert offer chronological reading plans if you prefer to follow the storyline in historical order.
