How Many Books in the Bible: Number, List & Chapters

Ask ten different people how many books are in the Bible and you’ll get at least three different answers. All of them are technically correct. If you grew up in a Protestant or evangelical church, you were handed a Bible with 66 books. Ask a Catholic priest and he’ll say 73. Ask an Ethiopian Orthodox scholar and the number climbs to 81. So the honest answer to “how many books in the bible” isn’t just a number — it’s a story about how different branches of the Christian faith have read, counted, and debated their scriptures for nearly two thousand years.

This guide gives you all of it: the quick count, the denomination breakdown, every one of the 66 books listed with chapters and verses, and how the books were actually chosen. Save this page. You’ll use it more than once.

Whether you’re a first-time reader wondering how many books in the bible there are, a student trying to map out the full scope of Scripture, or someone who just heard a Catholic friend mention books you’ve never encountered — this is the page to bookmark.

The Short Answer: 66 Books in the Protestant Bible

The Protestant and evangelical Christian Bible contains 66 books — 39 in the Old Testament and 27 in the New Testament. That has been the standard for most English-speaking Christians since the Reformation of the 1500s.

The word “Bible” itself comes from the Greek βιβλία (biblia) — the plural of biblion, meaning “small book” or “scroll.” The Bible is literally “the books.” It’s a library, not a single volume. That detail matters, because it reminds us that the word of God came through dozens of authors, across roughly 1,500 years, in three different languages.

The Old Testament records God’s relationship with the people of Israel — from creation through the exodus, the settlement of the promised land, the reign of King David and King Solomon, the building of the temple, the split into the northern kingdom and southern kingdom, the Babylonian exile, and the return. The New Testament opens with the life of Jesus Christ, continues through the early church and the missionary journeys of the Apostle Paul, and closes with the prophetic vision of Revelation.

Wait — Not Every Bible Has 66 Books

Here’s what most people don’t know: the debate over how many books belong in the Bible is not a modern controversy. It’s ancient. And different parts of the Christian family have held different positions for centuries.

Every tradition accepts the same 27 New Testament books. The disagreements are entirely about the Old Testament — specifically about a collection of writings composed between roughly 400 BC and 100 BC, after the Hebrew prophets went silent and before the New Testament era began.

4 Words That Explain All the Confusion

Most of the debate over how many books are in the Bible comes down to four terms. Once you know these, the entire conversation makes sense.

The Hebrew Bible Counts the Same Books as 24, Not 39

Here’s the part most Bible surveys skip entirely. The Jewish faith reads the same books as the Protestant Old Testament — but counts them differently. The result: 24 books instead of 39.

The Hebrew Bible is called the Tanakh (תַּנַ”ךְ) — an acronym formed from its three sections: Torah (the Law), Nevi’im (the Prophets), and Ketuvim (the Writings).

For example, in the Hebrew Bible, 1 Samuel and 2 Samuel are one book. So are 1 Kings and 2 Kings, 1 Chronicles and 2 Chronicles, and Ezra and Nehemiah. The 12 minor prophets — from Hosea through Malachi — are counted as a single book called “The Twelve.”

Same text. Same content. Different counting system. This is why when Jesus and his disciples quoted “the Scriptures,” they were referencing what we now call the Old Testament — but organized as their own people had always organized it. For more on how the Hebrew prophets fit together, the Sons of Issachar Bible study guide digs into how understanding the times was tied directly to knowing the full scope of those writings.

The 7 Extra Books Catholics Include

The Roman Catholic Bible includes 7 books — and additions to 2 existing books — that you won’t find in a Protestant Bible. These are the deuterocanonical books. They were written between approximately 300 BC and 100 BC, a period sometimes called the intertestamental period — after the last Hebrew prophets and before the New Testament era.

These books were part of the Septuagint — the Greek translation of the Old Testament widely used by early Christians. Many early church fathers quoted from them. However, Jerome, who translated the Latin Vulgate Bible in the 4th century, noted that some of these books weren’t in the Hebrew canon. That distinction quietly planted a seed that would eventually become the Protestant position.

Martin Luther formalized the split during the Protestant Reformation. He moved the apocryphal books to a separate section between the Old and New Testaments, noting they were “useful and good to read” but not on the same level as canonical Scripture. Most Protestant Bible publishers eventually dropped them altogether. The Roman Catholic Church, by contrast, formally confirmed all 7 as canonical at the Council of Trent in 1546.

How the Books of the Bible Were Actually Chosen

This is where popular mythology often gets it completely wrong. Let’s clear it up directly.

What Actually Happened — The Real Timeline

The process of defining the biblical canon developed gradually over several centuries. By the late first century, most of the New Testament books were already being circulated and read in churches across the Roman Empire. Early Christians quoted them, copied them, and treated them as authoritative — long before any church council made it official.

The early church fathers — including Origen, Athanasius, and Eusebius — discussed and debated which books belonged in the New Testament canon throughout the 2nd and 3rd centuries. Athanasius, in his Festal Letter of 367 AD, listed all 27 New Testament books we have today — the first surviving document to list them exactly.

The new testament canon was formally confirmed at the Synod of Hippo in 393 AD and reaffirmed at the Council of Carthage in 397 AD. These were regional African councils attended by early Christians, not grand imperial gatherings. Augustine of Hippo was a key figure at both. The early church’s criteria for inclusion included: apostolic origin (written by an apostle or close associate), consistency with the rule of faith, and widespread use across churches.

For the Old Testament, the Hebrew scriptures had long been accepted as God’s word. The debate was over whether the deuterocanonical books should be included — a question that remained officially unresolved in the Western church until the Council of Trent in 1546.

The Writers Behind the Word of God

The Bible wasn’t written by one person or in one generation. It came together over roughly 1,500 years through about 40 different authors — shepherds, kings, fishermen, priests, tax collectors, and scholars. That’s one of the most remarkable things about the word of God: the consistency of its central message across such a span of time and such different human voices.

Moses wrote the first five books of the Bible — the Torah — which include Genesis, Exodus, and the events at Mount Sinai. King David wrote the majority of the Psalms. King Solomon gave us Proverbs, Ecclesiastes, and the Song of Solomon. The prophets Isaiah, Jeremiah, and Ezekiel each wrote major books; the 12 minor prophets added their voices during and after the Babylonian exile.

In the New Testament, the Apostle Paul wrote 13 of the 27 books — more than any other single author. His Pauline epistles, from Romans to Philemon, account for a significant portion of Christian theology. John wrote the Gospel of John, the three letters of John, and the book of Revelation. Luke wrote both the Gospel of Luke and the Acts of the Apostles — together the longest contribution to the New Testament by word count.

The Holy Spirit working through ordinary people, over centuries, producing a text that reads as one coherent story from Genesis to Revelation — that’s the claim at the heart of the Christian bible. Whether you’re new to it or have read it many times, understanding which person wrote which part helps each book land with more weight.

“All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness.” — 2 Timothy 3:16 (NIV)

Paul wrote those words near the end of his life, in prison, referring to what we now call the Old Testament. He had no idea his own letters would one day be included in the canon alongside them. That’s part of what makes the question of how many books in the bible so historically fascinating — the answer didn’t arrive overnight. For a deeper look at how the Bible’s most central theme — love — runs from Genesis to Revelation, that post breaks down the count across every major translation.

How to Read All 66 Books in Chronological Order

The canonical order of the bible books — Genesis through Revelation — is not the order in which they were written. If you want to read the Bible in the order events happened and books were composed, a chronological order approach changes the experience significantly.

For example, Job is likely the oldest book in the Bible by writing date — predating even the Exodus accounts. The Psalms were written across centuries. Paul’s letters were written before the Gospels were finalized in their current form.

Here’s a broad chronological grouping to use as a reading framework:

There are also excellent reading plans built on this framework — including one-year plans that take you through the entire Bible by reading roughly 3–4 chapters per day. The chronological approach is especially useful for understanding the context behind the minor prophets, since each of them was speaking into a specific moment in Israel’s history.
