Scripture & Tradition
The Bible & Catholicism
Did the Catholic Church create the Bible — or preserve it? The story of how Scripture came to be, who decided what belongs in it, and what Catholics believe about the Word of God.
The relationship between the Catholic Church and the Bible is one of the most misunderstood topics in Christian history. The Church did not invent the Bible — but it did recognize, preserve, copy, and transmit it across 2,000 years. Understanding that relationship changes everything.
A Note on Clarity
This page distinguishes carefully between three things: (1) established historical facts, (2) Catholic teaching and doctrine, and (3) arguments and inferences drawn from evidence. Where something is disputed or debated, that is noted. The goal is honest engagement with the evidence, not propaganda.
Eight Things to Understand
Each section is labeled so you know exactly what kind of claim is being made.
The word 'canon' comes from the Greek kanon, meaning 'rule' or 'measuring rod.' The canon of Scripture is the official list of books recognized as divinely inspired and authoritative. The canon was not self-evident — early Christians debated which books belonged, and the process of recognition took centuries.
The New Testament canon as we know it — 27 books — was not formally defined until the late 4th century. The earliest complete list matching the modern Catholic/Protestant New Testament appears in Athanasius's Festal Letter of 367 AD. The Council of Rome (382 AD) and the Councils of Hippo (393 AD) and Carthage (397 AD, 419 AD) confirmed the canon under Pope Damasus I. These were Catholic councils, with Catholic bishops, making Catholic decisions — decisions that Protestant Christians still rely on for their New Testament.
Key Point
The 27-book New Testament canon was defined by Catholic councils in the 4th century. No council, no canon.
2 Timothy 3:16–17
"All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness."
