How many books are in the Bible?
How many books are in the Bible? The answer depends on which Bible you’re reading.
There isn’t just one Bible. Depending on your religious tradition, the total number of books can range from 24 to 81. The Protestant Bible contains 66 books, the Catholic Bible includes 73, and the Eastern Orthodox Bible can go up to 81. The Hebrew Bible — or Tanakh — includes just 24 books, though many of the same texts appear in multiple versions under different arrangements.
These variations come from centuries of religious history, theological debate, and cultural influence. While all Christian Bibles include the same 27 books of the New Testament, they differ widely in their Old Testament content. Some include additional texts known as the deuterocanonical books (Catholic) or the apocrypha (Protestant terminology). Others, like the Ethiopian Orthodox tradition, have an even broader collection that incorporates texts such as Jubilees and Enoch.
So, there’s no single number that answers this question. Instead, the count reflects a long history of translation, canonization, and tradition. Asking “how many books are in the Bible” is really a way of asking whose Bible are we talking about?
Let’s explore the main traditions one by one.

✝️ Protestant Bible – 66 Books
The Protestant Bible contains 66 books: 39 in the Old Testament and 27 in the New. This version was shaped during the 16th-century Reformation, when Martin Luther and other reformers sought to align Christian Scripture more closely with the Jewish canon.
The Old Testament in Protestant Bibles excludes seven books found in the Catholic tradition, including Tobit, Judith, Wisdom, and 1 and 2 Maccabees. These books, often called the Apocrypha by Protestants, are considered valuable historical or devotional works—but not divinely inspired Scripture.
The structure of the Protestant Old Testament is similar to the Hebrew Bible but with rearranged and divided books. For example, 1 and 2 Kings are treated as separate volumes, and the Twelve Minor Prophets are counted individually rather than as a single book.
This canon became the standard for most English-language Bibles, including the King James Version (1611). Today, it’s used by evangelical, Anglican, Baptist, Methodist, and many other Protestant churches worldwide.
Its focus on 66 books makes it both accessible and deeply influential. But it’s important to remember: this structure is just one version of a much larger scriptural tradition.
✝️ Catholic Bible – 73 Books
The Catholic Bible contains 73 books: 46 in the Old Testament and 27 in the New Testament. It includes all the texts of the Protestant Bible, plus seven additional Old Testament books known as the deuterocanonical books.
These include Tobit, Judith, Wisdom of Solomon, Sirach (Ecclesiasticus), Baruch, and 1 and 2 Maccabees. The Catholic canon also incorporates longer versions of Daniel and Esther, with passages not found in Protestant editions.
The Catholic Church officially recognized this canon during the Council of Trent (1545–1563), reaffirming texts that had been widely used in early Christian liturgy but later questioned during the Reformation.
The deuterocanonical books are important to Catholic theology. They address themes like resurrection (2 Maccabees), divine wisdom (Wisdom of Solomon), and social justice (Sirach). Many were written in Greek and included in the Septuagint, a Greek translation of the Hebrew Scriptures that was widely used in the early Church.
Catholic Bibles like the Douay-Rheims, Jerusalem Bible, and New American Bible preserve this expanded canon. These editions are used in liturgy, catechism, and devotional study across the global Catholic world.
So while the Catholic Bible shares much with the Protestant one, its inclusion of additional books reflects a broader view of sacred history and divine inspiration.
✝️ Eastern Orthodox Bible – Up to 81 Books
The Eastern Orthodox Bible contains a wider set of books than either the Catholic or Protestant traditions. Most Eastern Orthodox Bibles include 79 to 81 books, depending on the branch and local customs.
In addition to the standard 27 New Testament books, the Eastern Orthodox canon embraces the 46 Old Testament books of the Catholic Bible and adds several more. These include 3 Maccabees, Psalm 151, 1 Esdras, 2 Esdras, and the Prayer of Manasseh. In the Ethiopian Orthodox Tewahedo Church, the number expands even further to include Enoch, Jubilees, and other ancient writings—reaching a total of 81 books.
These extra books are not considered “optional.” They’re often treated as fully canonical and used in liturgical readings and teaching. The Orthodox canon reflects the early use of the Septuagint, which contained many of these writings and influenced the theology of the early Church Fathers.
Unlike the fixed structure of Catholic or Protestant Bibles, Orthodox Bibles can vary depending on region—Greek, Russian, Ethiopian, and Coptic traditions may differ slightly. But the openness to additional texts reflects a theological flexibility rooted in early Christian history.
This diversity makes the Orthodox Bible one of the most fascinating—and expansive—canons in Christianity.
✡️ Hebrew Bible (Tanakh) – 24 Books
The Hebrew Bible, also known as the Tanakh, contains 24 books, arranged into three sections: Torah (Law), Nevi’im (Prophets), and Ketuvim (Writings).
Despite the smaller number, the Hebrew Bible covers most of the same material as the Protestant Old Testament. The difference lies in how the books are counted and grouped. For example, 1 and 2 Samuel are considered one book. The Twelve Minor Prophets are also treated as a single unit. Books like Ezra and Nehemiah are merged, as are Chronicles I and II.
This structure was standardized in Jewish tradition over centuries and reflects the Hebrew and Aramaic texts used by ancient communities. It does not include the New Testament, which is not recognized in Judaism.
The Tanakh is the foundation of Jewish religious life and is written entirely in Hebrew (with some Aramaic passages). It has been passed down for millennia and remains the heart of synagogue worship, Torah study, and Jewish identity.
While Christianity expanded upon these texts with the New Testament and additional writings, the Tanakh stands on its own—a profound and deeply influential sacred library of 24 books.

📚 Aldous Huxley and the Biblical Canon of Control
Aldous Huxley’s Brave New World may be set in a sterile future, but its roots stretch deep into questions of spiritual control. One fascinating layer: Huxley’s knowledge of religious canon. He knew very well that even something as seemingly fixed as the Bible could be restructured by those in power. In Brave New World, religious texts are banned or warped into parody. Only sanitized slogans remain — no 73-book Catholic Bible or 81-book Orthodox version allowed.
Huxley came from a deeply intellectual family and was steeped in theology, mysticism, and the history of the sacred. He even wrote The Perennial Philosophy, comparing religious traditions across time. For Huxley, the idea that a sacred canon could be reshaped by institutional choice wasn’t strange — it was central. The Bible’s variable structure wasn’t a flaw, but a demonstration of power dynamics at play in society.
So when we ask how many books are in the Bible, we’re also asking: who gets to decide what’s sacred? Huxley understood that question better than most — and his dystopia warns what happens when those decisions are made without freedom of thought.
📖 Marcel Proust and the Intimacy of Lost Texts
Marcel Proust’s monumental novel, In Search of Lost Time, rarely references the Bible directly. But the emotional and symbolic weight of ancient, layered texts hovers throughout his work. Like the many biblical canons — some with 66 books, others with 81 — Proust’s novel feels almost scriptural in its structure. It’s not a stretch to say he created his own literary canon of memory and emotion.
In one passage, the narrator reflects on the weight of forgotten books, of dusty stories once revered. There’s something biblical in that — the echo of lost Gospels, of disputed letters, of books like Enoch or Baruch, present in some Bibles and missing in others. Proust captures that same tension: which stories survive, and which ones are allowed to shape our lives?
If you read Proust slowly — as one must — you’ll feel that sacred drift. A minor character’s gesture becomes as powerful as a parable. A memory of a church or the taste of a madeleine can seem as enduring as Genesis. Proust reminds us: the Bible is not just a collection of fixed books — it’s a metaphor for how memory preserves what matters.
📘 Victor Hugo and the Bible of Revolution
Victor Hugo had a complicated relationship with religion, but he never denied the symbolic force of the Bible. In Les Misérables, biblical echoes abound: forgiveness, judgment, resurrection. Yet Hugo lived in a France where multiple Bibles circulated — Protestant, Catholic, and philosophical. He saw religion not just as doctrine, but as narrative power.
When Jean Valjean transforms from convict to savior, it’s not unlike a gospel tale. Hugo often wrote in a grand, almost prophetic voice. He knew the Bible came in many shapes — 66 books, 73 books, even more in the East — and he used that flexibility to his advantage. His speeches in Parliament, his poetic works, and even his exile writings often cast him as a voice crying in the wilderness.
Hugo once wrote, “There is one thing stronger than all the armies in the world: an idea whose time has come.” For many, the Bible is exactly that — a layered idea, reborn in every age, canonized and recanonized by the pressures of politics and culture. Hugo, more than most, understood that the number of books is less important than the stories we allow to shape us.
