Who Wrote the Bible? Unraveling the Mystery of the Authors Behind Christianity's Sacred Text

Who wrote the Bible is a fascinating question that leads us to explore the diverse range of human authors, from the Old Testament prophets to the New Testament apostles and their companions, who contributed to this sacred text. 

The Bible, the foundational and sacred text for Christianity, is a complex compilation of writings authored by various individuals over thousands of years. 

But who were these authors who wrote the Bible, and how did their diverse backgrounds and experiences contribute to the richness of the biblical narrative?

Divine Inspiration

Before we look into the individual authors, it is essential to understand the Christian belief about the nature of the Bible's authorship. 

According to 2 Timothy 3:16-17, "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, so that the man of God may be complete, equipped for every good work." 

This concept of 'God-breathed' suggests that while humans penned the words, they were inspired by God, serving as His instruments. They did not write their own thoughts or opinions, but rather what the Holy Spirit led them to write (2 Peter 1:20-21).

Who Wrote the Old Testament?

The Old Testament is composed of 39 books in the Protestant Bible, and additional books, which are called deuterocanonical books, in the Roman Catholic and Eastern Orthodox Bibles. 

The authorship of these books spans a vast range of time and incorporates many different voices, often with varying perspectives and experiences. 

Let us explore the authors of the Old Testament books, including the deuterocanonical books, based on the best available evidence.

The First Five Books

Traditionally, Moses is believed to have authored the first five books of the Old Testament, known as the Torah or the Pentateuch. These books – Genesis, Exodus, Leviticus, Numbers, and Deuteronomy – provide the foundation of Jewish and Christian beliefs.

The Historical Books

The historical books, from Joshua to 2 Chronicles, have various authors. Joshua, the book's protagonist, is traditionally credited with writing the Book of Joshua. 

The Books of Samuel are believed to have been written by Samuel, Nathan, and Gad, while the Books of Kings were likely authored by Jeremiah. The Books of Chronicles are attributed to Ezra, the priest and scribe.

The Wisdom Literature

The wisdom literature, which includes Job, Psalms, Proverbs, Ecclesiastes, and Song of Songs, has several known authors. 

David is credited with many of the Psalms, while Solomon is traditionally associated with Proverbs, Ecclesiastes, and the Song of Songs. The Book of Job's authorship is uncertain.

The Prophets

The major prophets – Isaiah, Jeremiah, and Ezekiel – are thought to have written their respective books. In addition, the Book of Lamentations is attributed to Jeremiah, and the Book of Daniel is attributed to Daniel himself. The twelve minor prophets are considered to be the authors of their eponymous books.

The Deuterocanonical Books

As for the deuterocanonical books, the authorship of Tobit, Judith, and the Wisdom of Solomon remains uncertain. 

The First and Second Books of Maccabees were likely written by different authors, whose identities are unknown. The Book of Baruch and the Letter of Jeremiah are attributed to Baruch, Jeremiah's scribe. 

Sirach, also known as Ecclesiasticus, was written by Ben Sira. The Books of 1 and 2 Esdras have uncertain authorship.

Who Wrote the New Testament?

The New Testament is a collection of sacred texts that make up the second major part of the Bible, focusing on the life, teachings, death, and resurrection of Jesus Christ. 

The New Testament consists of 27 books, written by various authors, many of whom were apostles or their associates.

The Gospels

The four Gospels, which provide the core narrative of Jesus' life, teachings, and actions, were written by four evangelists: Matthew, Mark, Luke, and John. 

Matthew, a tax collector turned disciple, authored the Gospel of Matthew. Mark, a close associate of the apostle Peter, is believed to have written the Gospel of Mark. 

Luke, a physician and companion of the apostle Paul, authored the Gospel of Luke and the Acts of the Apostles. 

Finally, John, one of Jesus' twelve apostles, is traditionally believed to have written the Gospel of John.

The Pauline Epistles

The apostle Paul is credited with authoring at least 13 of the 21 epistles in the New Testament. These letters, written to various churches and individuals, include Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians, 1 and 2 Timothy, Titus, and Philemon. 

The authorship of the Epistle to the Hebrews remains uncertain, although it is often attributed to Paul.

The General Epistles

The remaining epistles, known as the General or Catholic Epistles, were written by various apostles and their associates. 

The apostle James authored the Epistle of James. Peter, one of Jesus' twelve apostles, wrote the First and Second Epistles of Peter. The First, Second, and Third Epistles of John are attributed to the apostle John. Finally, the Epistle of Jude was written by Jude.

The Book of Revelation

The Book of Revelation, a prophetic and apocalyptic text, was written by John, who is traditionally identified as the apostle John.


The above narrative answers the question “Who wrote the Bible?” The Bible is a remarkable collection of diverse voices that encapsulates the experiences and wisdom of countless authors over millennia. 

The Scriptures represent the divine words of God, penned by human authors. Recognizing the Bible's multifaceted authorship helps us appreciate the ways in which God has been shepherding His people throughout history. 

It also underscores the significance of salvation, the redemption of our souls, and the gift of eternal life through Jesus Christ.
