Who Wrote the Bible?
The short answer: the Bible isn't the work of one author, or even one century. It's a collection of 66 books (in most Protestant Bibles; Catholic and Orthodox canons include more), written by roughly 40 different people, across a span of about 1,500 years.
The Old Testament
Tradition attributes the first five books (the Pentateuch, or Torah) to Moses, though scholars debate how much of the text reached its final form through later editing. Beyond that, Old Testament authorship spans kings (David is credited with many Psalms, Solomon with Proverbs and Ecclesiastes), prophets writing under specific historical pressure (Isaiah, Jeremiah, Ezekiel), and historical books whose authors are simply not named in the text.
The New Testament
The New Testament was written over a much shorter window — roughly 50 to 100 years after Jesus's death. Paul is credited with the largest share, having written (or being traditionally credited with) 13 of the 27 New Testament books, mostly letters to specific churches addressing specific problems. The four Gospels are attributed to Matthew, Mark, Luke, and John, though Mark and Luke were not among Jesus's twelve original disciples.
How it came together as one book
The Bible wasn't compiled all at once. The process of deciding which texts belonged — called canonization — happened gradually, through councils and widespread use across early Christian communities, with the New Testament canon largely settled by the 4th century.
Why this matters
Knowing the Bible has many human authors, writing in different centuries for different original audiences, changes how you read it — a letter Paul wrote to a specific troubled church in Corinth is doing something different than a Psalm written for worship, even though both are Scripture.

Frequently asked questions
Who wrote the Bible?
The Bible was written by roughly 40 different authors over about 1,500 years. They include Moses (traditionally credited with the first five books), kings such as David and Solomon, prophets including Isaiah and Jeremiah, the Gospel writers Matthew, Mark, Luke, and John, and the apostle Paul, who wrote or is credited with 13 of the 27 New Testament books.
Did Moses write the first five books of the Bible?
Tradition attributes the Pentateuch — Genesis, Exodus, Leviticus, Numbers, and Deuteronomy — to Moses. Scholars debate how much of the text reached its final form through later editing, but the Mosaic attribution is the historic Jewish and Christian position.
How many authors wrote the Bible?
About 40, writing across roughly 1,500 years, in three languages (Hebrew, Aramaic, and Greek) and on three continents. Some books, such as several Old Testament histories, do not name their author at all.
Who decided which books went in the Bible?
The process is called canonization. It happened gradually through widespread use in Jewish and early Christian communities and was later affirmed by church councils, with the New Testament canon largely settled by the 4th century.
