Who decided which books went into the Bible?
A powerful church council (perhaps under Emperor Constantine at Nicaea) picked the books that supported its theology and suppressed other gospels, like Thomas and Judas, that told a different story about Jesus. The Bible is the product of politics, not of God.
— A popular claim, given wide currency by Dan Brown's novel The Da Vinci Code (2003)
No council invented the Bible. The core of the New Testament (the four Gospels and Paul's letters) was already recognized as Scripture by the mid to late second century, long before any emperor was Christian. The church did not create authority; it recognized writings with apostolic origin, early use across the churches and teaching consistent with the faith. Later gospels like Thomas and Judas were written too late to pass those tests. Nicaea (325) did not discuss the canon at all.
What Scripture says
44Jesus said to them, “These are the words I spoke to you while I was still with you: Everything must be fulfilled that is written about Me in the Law of Moses, the Prophets, and the Psalms.”
Jesus refers to the Law of Moses, the Prophets and the Psalms, the threefold shape of the Hebrew Scriptures.
1What, then, is the advantage of being a Jew? Or what is the value of circumcision? 2Much in every way. First of all, they have been entrusted with the very words of God.
Paul says the Jews were entrusted with the oracles of God. The Old Testament came to the church through Israel.
15Consider also that our Lord’s patience brings salvation, just as our beloved brother Paul also wrote you with the wisdom God gave him. 16He writes this way in all his letters, speaking in them about such matters. Some parts of his letters are hard to understand, which ignorant and unstable people distort, as they do the rest of the Scriptures, to their own destruction.
Peter already places Paul's letters alongside 'the other Scriptures'.
18For the Scripture says, “Do not muzzle an ox while it is treading out the grain,” and, “The worker is worthy of his wages.”
Paul cites Deuteronomy 25:4 and a saying found in Luke 10:7 together as 'Scripture'.
26But the Advocate, the Holy Spirit, whom the Father will send in My name, will teach you all things and will remind you of everything I have told you.
Jesus promises the Spirit would remind the apostles of his teaching, grounding apostolic authority.
6I am amazed how quickly you are deserting the One who called you by the grace of Christ and are turning to a different gospel— 7which is not even a gospel. Evidently some people are troubling you and trying to distort the gospel of Christ. 8But even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be under a curse! 9As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be under a curse!
Even early on, there was a recognized apostolic gospel against which rival messages were measured.
3Beloved, although I made every effort to write to you about the salvation we share, I felt it necessary to write and urge you to contend earnestly for the faith entrusted once for all to the saints.
The faith was 'once for all delivered', a fixed deposit that later writings were tested against.
The case
The Old Testament: received from Israel
Jesus and the apostles inherited a body of Scripture from Israel. Jesus refers to it by its threefold shape: the Law, the Prophets and the Psalms (Luke 24:44). He quotes it as the Word of God, and he and the apostles cite it hundreds of times. Christians did not need to decide the core of the Old Testament; they received it. The main difference among Christian traditions concerns some additional Jewish writings from the centuries before Christ (see Christians differ).
The New Testament: recognized, not invented
1. The core was recognized very early
- Within the New Testament itself, Paul's letters are placed alongside "the other Scriptures" (2 Peter 3:16), and a saying of Jesus found in Luke is quoted as Scripture (1 Timothy 5:18).
- Early second-century writers such as Clement of Rome, Ignatius and Polycarp quote or allude to many New Testament books.
- Around AD 180, Irenaeus of Lyon argues that there are four Gospels, no more and no fewer (Against Heresies 3.11.8). This was not a new idea he had to defend; he treats the fourfold Gospel as established.
- The Muratorian Fragment, a Latin list of New Testament books, is traditionally dated to the late second century, though some scholars date it to the fourth.
2. The church used three main tests
| Test | Question asked |
|---|---|
| Apostolicity | Was it written by an apostle or a close associate (e.g., Mark with Peter, Luke with Paul)? |
| Catholicity (universal use) | Was it read and received in churches widely, not just in one sect? |
| Orthodoxy | Did it agree with the "rule of faith", the apostolic teaching handed down? |
These tests looked backward to the apostolic generation. They were not a way of picking favorite theology; they asked where a book came from.
3. A few books were debated, and that's healthy
In the early fourth century the historian Eusebius sorted books into those acknowledged by all, those disputed, and those rejected (Ecclesiastical History 3.25). The disputed ones were mostly short letters and Revelation. In AD 367 Athanasius of Alexandria listed exactly the 27 books of today's New Testament in his Festal Letter 39. Regional councils at Hippo (393) and Carthage (397) confirmed the same list in the West. These councils ratified what the churches already used; they did not hand down a new list.
What about the "lost gospels"?
Works like the Gospel of Thomas, Gospel of Peter and Gospel of Judas are genuinely interesting historical documents. But most scholars date them to the second century or later, generations after the apostles. Many reflect Gnostic ideas (that salvation comes through secret knowledge and that the material world is inferior or evil) that are foreign to the Jewish setting of Jesus. They were not "suppressed" from the canon. They were never in serious contention, because they failed the tests of origin and widespread use.
Why it matters
The question of the canon is really a question of trust: did God give his people a reliable witness to Jesus? The history shows a church that was cautious and resistant to novelty, and that wanted to hear the apostles' voices. In these books we meet the Jesus the eyewitnesses knew, and Athanasius called them "fountains of salvation" (Festal Letter 39).
Word study
greek · “rule, measuring standard” · Galatians 6:16
Our word 'canon' comes from kanōn, a straight rod or measuring rule. Applied to Scripture, it means the books are the standard that measures the church's teaching. The term itself implies a standard the church submits to, not one it invents.
“But what about…?”
Didn't Constantine choose the books at the Council of Nicaea?
No. The Council of Nicaea (AD 325) dealt with the Arian controversy about the deity of Christ and with the date of Easter. Its surviving canons and creed say nothing about which books belong in the Bible. Constantine did commission fifty Bibles for Constantinople (Eusebius, Life of Constantine 4.36), but he did not define their contents.
Why weren't the Gospel of Thomas or the Gospel of Judas included?
Most scholars date them to the second century or later; the Gospel of Judas is usually dated to the mid second century. They show the influence of later Gnostic thought, and they were not widely used in the churches. The four canonical Gospels were already being treated as a set by Irenaeus around AD 180 (Against Heresies 3.11.8).
If the church recognized the books, doesn't the church have authority over Scripture?
Christians answer this differently (see below). But all agree the church received rather than manufactured these books. A prospector who identifies gold does not make it gold.
Why did it take until the fourth century to settle?
The core was settled early; debate concerned a few smaller books, such as 2 Peter, James, Jude, 2 and 3 John, Hebrews and Revelation. Churches were scattered across an empire under intermittent persecution, with no central authority to issue lists. The slow, cautious process is evidence of care, not conspiracy.

Related questions
Hasn't the Bible been changed and corrupted over time?
No ancient book is better attested than the New Testament. More than 5,700 Greek manuscripts survive, some within a century or two of the originals, plus early translations and quotations by church fathers. Because the copies spread widely and independently, scholars can compare them and recover the original wording with high confidence. Most variants are spelling slips, and the few meaningful ones are openly flagged in modern Bibles. None overturns a core Christian belief.
Isn't the Bible just a translation of a translation?
Modern Bibles are not the end of a chain of translations. Translators work directly from Hebrew, Aramaic and Greek texts reconstructed from thousands of ancient manuscripts, so your English Bible is one step from the original languages, not dozens. The telephone game also fails as an analogy: it has one line, one whisper at a time, and no way to check. The Bible has many independent lines that can be compared, and the earliest copies can always be checked.
Isn't the Bible full of contradictions?
A contradiction means two statements cannot both be true in the same sense at the same time. Most alleged contradictions are differences: different details, perspectives, summaries or emphases, the kind you expect from independent witnesses. A few involve likely copying errors in numbers, which ancient scribes and modern translators openly note. Read with the same fairness we give other ancient historians, the Bible's differences point to independent testimony, not fabrication.
Does archaeology support the Bible?
Archaeology can't prove spiritual claims like 'God spoke', but it can test the Bible's historical setting, and it has repeatedly confirmed real people, places and events. Inscriptions name David's dynasty, Israelite and Judean kings, Pontius Pilate and the high priest Caiaphas. Sites like the Pool of Siloam match the Gospels. Some questions remain debated, and absence of evidence is not proof of absence, but the Bible consistently fits the ancient world it describes.
