Books of the Bible and Their Authors: A Complete Guide to All 66 Books
The Bible is not a single book written by one human author. It is a collection of books written across different periods of history by prophets, kings, apostles, leaders, and other servants of God.
The Protestant Bible contains 66 books: 39 books in the Old Testament and 27 books in the New Testament. Although Christians believe that Scripture was inspired by God, God used human writers with different backgrounds, experiences, vocabulary, and writing styles.
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.”
— 2 Timothy 3:16 (KJV)
This guide lists the books of the Bible and their traditional or commonly understood human authors. Where a book does not identify its author clearly, that uncertainty is noted rather than presenting a tradition as an established fact.
Who Wrote the Bible?
Christians understand the Bible as the inspired Word of God while also recognizing that God worked through human writers.
The apostle Peter explains:
“For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.”
— 2 Peter 1:21 (KJV)
Some biblical books identify their writers directly. Paul's letters, for example, commonly begin by naming Paul. Other books are connected with their authors through ancient Jewish or Christian tradition. A number of books remain anonymous.
Old Testament Books and Their Authors
The Old Testament contains 39 books in the traditional Protestant arrangement. These books include the Law, historical books, poetry and wisdom literature, and the prophets.
The Five Books of Moses — The Pentateuch
The first five books of the Bible are traditionally associated with Moses and are often called the Pentateuch or the Torah.
| Book | Traditional / Commonly Understood Author |
|---|---|
| Genesis | Moses |
| Exodus | Moses |
| Leviticus | Moses |
| Numbers | Moses |
| Deuteronomy | Moses; the account of his death was recorded by another hand |
These books describe creation, humanity's fall into sin, the patriarchs, Israel's deliverance from Egypt, God's covenant with Israel, the giving of the Law, and Israel's journey toward the Promised Land.

| Ecclesiastes | The book identifies its speaker as “the Preacher”; traditionally associated with Solomon |

Major Prophets
The designation “Major Prophets” refers mainly to the length of these prophetic books, not to the prophets being more important than the Minor Prophets.

| Jeremiah | Jeremiah; Baruch served as his scribe in portions of his ministry |
| Lamentations | Anonymous; traditionally attributed to Jeremiah |
| Ezekiel | Ezekiel |

The Four Gospels
The four Gospels present the life, ministry, teachings, death, and resurrection of Jesus Christ.
| Book | Traditional Author |

| Matthew | Matthew, the apostle and former tax collector |
| Mark | John Mark, traditionally connected with the testimony of Peter |

Who Wrote the Book of Acts?
The book of Acts is traditionally attributed to Luke, the same writer associated with the Gospel of Luke.
Luke and Acts are addressed to Theophilus and form a connected account. Luke focuses on Jesus' ministry, while Acts describes the spread of the Gospel and the growth of the early church.
| Book | Traditional Author |
|---|---|
| Acts | Luke |

Who Wrote Hebrews?
Hebrews is one of the clearest examples of why biblical authorship should sometimes be presented cautiously.
The book itself does not identify its human author.
Various individuals have been proposed throughout Christian history, including Paul, Barnabas, Luke, Apollos, and others. None of these proposals can be established conclusively from the text.
| Book | Author |
|---|---|
| Hebrews | Unknown |
Rather than claiming certainty where Scripture does not provide it, it is more accurate to say that the human author of Hebrews is unknown.
The General Epistles
The remaining New Testament letters are often called the General or Catholic Epistles.
| Book | Traditional / Commonly Understood Author |
|---|---|
| James | Traditionally James, the brother of Jesus |
| 1 Peter | Peter the apostle |
| 2 Peter | Traditionally Peter the apostle |
| 1 John | Traditionally John the apostle |
| 2 John | “The elder,” traditionally identified with John |
| 3 John | “The elder,” traditionally identified with John |
| Jude | Jude, who identifies himself as the brother of James |
Who Wrote Revelation?
The final book of the Bible identifies its writer as John.
“The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass...”
— Revelation 1:1 (KJV)
John explains that he was on the island of Patmos when he received the revelation.
| Book | Author |
|---|---|
| Revelation | John; traditionally identified as John the apostle |

Did One Person Write the Bible?
No single human being wrote all the books of the Bible. Scripture developed through many human writers and across different historical settings.
Christians nevertheless understand these writings as forming one unified body of Scripture because of their divine inspiration.
This means that discussions about biblical authorship have two related dimensions: the human writers responsible for individual books and the Christian doctrine that Scripture ultimately comes from God.
Why Are Some Biblical Authors Unknown?
Modern books normally place the author's name prominently on the cover. Ancient writings did not always follow this practice.
Some biblical books identify their writers clearly, while others do not. In some cases, later Jewish or Christian traditions associated a particular person with a book.
When Scripture does not identify an author and historical evidence does not establish one conclusively, Christians should be careful about claiming more certainty than the evidence permits.
This does not diminish the spiritual value or authority of a biblical book. For example, the human author of Hebrews remains uncertain, yet Hebrews has been received and studied as part of the New Testament throughout Christian history.
Understanding Divine and Human Authorship
The Bible presents Scripture as originating from God while being communicated through human beings.
This helps explain why biblical books have different literary styles. Psalms contains poetry and worship. Proverbs contains wisdom sayings. The Gospels present accounts of Jesus Christ. Paul's writings often take the form of letters addressed to churches or individuals. Revelation contains prophetic and apocalyptic imagery.
The diversity of human writers does not remove the Christian conviction of divine inspiration.
“All scripture is given by inspiration of God.”
— 2 Timothy 3:16 (KJV)
Why Study the Authors of the Bible?
Knowing about biblical authorship can help students understand Scripture more carefully.
It Helps Us Understand Historical Context
Knowing who wrote a book—or what can reasonably be known about its historical setting—can help explain its audience, circumstances, vocabulary, and purpose.
It Helps Us Understand Different Biblical Genres
The Bible contains history, law, poetry, wisdom literature, prophecy, Gospel narratives, letters, and apocalyptic literature.
Recognizing these differences helps students interpret individual passages responsibly.
It Encourages Deeper Bible Study
Learning about authorship naturally leads to other useful questions: Who was the original audience? Why was the book written? What historical circumstances surrounded it? What major themes does it contain?
These questions can move Bible study beyond isolated verses toward understanding entire books in context.
Conclusion: Many Writers, One Biblical Story
The Bible contains 66 books written through many human authors and produced in different historical settings.
Moses is traditionally associated with the first five books. David and others contributed Psalms. Prophets such as Isaiah, Jeremiah, Ezekiel, and others delivered God's messages. Matthew, Mark, Luke, and John are traditionally associated with the four Gospels. Paul wrote numerous New Testament letters, while Peter, James, Jude, John, and others contributed additional writings.
For some books, such as Hebrews, the identity of the human author remains uncertain.
Yet Christians recognize these diverse writings together as Scripture and believe that God worked through human writers to communicate His Word.
Understanding who wrote the books of the Bible is therefore an excellent starting point for deeper study. The next step is to explore each book's historical setting, original audience, purpose, major themes, and contribution to the message of Scripture.
