Question guide
When was the New Testament canon fixed?
Short answer
The New Testament canon emerged gradually. Many core books were widely received early, but the first surviving list matching the modern 27-book New Testament is Athanasius in AD 367.
Key points
- The four Gospels and many Pauline letters were widely used by the late second century.
- Books such as Hebrews, Revelation, James, 2 Peter, 2-3 John, and Jude remained disputed in some places.
- Fourth-century codices show that copyists still handled some boundary books differently.
- Athanasius gives the first surviving 27-book list matching the modern New Testament in AD 367.
