Who Picked the Books of the Bible?

Open any Bible and you’ll find a table of contents. Here’s a question few people ever ask: who decided what goes on that list?

It’s a fair question, because the books didn’t arrive with the list attached. For centuries after the earliest Christian writings were composed, there was no official New Testament. Different congregations read different collections. Some read books that aren’t in any Bible today. The list itself, what scholars call the canon, took shape slowly, through human discussion, disagreement, and decision. None of this is a hostile claim, and it isn’t hidden. It’s the standard history, documented in any good reference work, and Christian scholars study it as intently as anyone.

How the List Took Shape

A few dates make the timeline concrete. The letters of Paul and the gospels were written in roughly the second half of the 1st century. In the mid-2nd century, a teacher named Marcion published one of the first known lists of Christian scripture, and the mainstream church rejected his choices, which pushed others to define their own. Church leaders spent the next two centuries debating which books were genuinely apostolic. The first surviving list that matches today’s 27-book New Testament exactly appears in the year 367, in an Easter letter from Athanasius, the bishop of Alexandria. Church councils at Hippo (393) and Carthage (397) endorsed similar lists.

That’s more than three hundred years between the writing of the books and a settled list of them. The people who made the decisions applied recognizably human criteria: Was the book believed to come from an apostle or an apostle’s companion? Did its teaching match what the church had come to consider sound? Was it widely read in the churches? Reasonable standards, thoughtfully applied. And unmistakably the work of people weighing evidence and preference, not a list handed down from heaven.

Books That Almost Made It

The clearest evidence that the canon was chosen rather than discovered is the books that nearly got in, or got in somewhere. Three examples are worth knowing:

A Christian book of visions and moral teaching from the early 2nd century, and one of the most popular Christian writings of its era. Several early church fathers treated it as scripture. In fact, if you browse Codex Sinaiticus, the oldest complete New Testament in existence, you’ll find the Shepherd of Hermas bound right in at the end, along with another non-canonical book, the Epistle of Barnabas. To the community that produced that Bible in the 4th century, these books belonged. Later decisions left them out, and most Christians today have never heard of them.

A collection of 114 sayings attributed to Jesus, known in fragments for over a century and recovered in full in 1945 among a cache of ancient books found near Nag Hammadi, Egypt. Some of its sayings closely parallel the canonical gospels; others sound very different. Scholars debate its date and how much independent tradition it preserves. What’s not debated is that some early Christians read it and valued it, and that it was excluded as the boundaries of acceptable teaching hardened. Whatever it is, it’s a window into how varied early Christianity actually was.

An ancient Jewish work describing the fall of the angels and visions of judgment, written centuries before Jesus. Most Jewish and Christian traditions eventually excluded it. But the New Testament letter of Jude quotes it directly, as prophecy. And the Ethiopian Orthodox Church includes Enoch in its Bible to this day. So a book quoted approvingly inside everyone’s New Testament is scripture in Ethiopia and excluded almost everywhere else. It’s hard to find a cleaner illustration that different communities drew the line in different places.

Christians Still Don’t Have One Bible

The disagreement never fully ended. Today, a Protestant Bible contains 66 books. A Catholic Bible contains 73, including books like Tobit and the Maccabees that Protestants set aside at the Reformation. Eastern Orthodox Bibles include a few more. The Ethiopian Orthodox canon runs to around 81 books. These aren’t fringe differences; they’re the settled positions of major branches of Christianity, each convinced its list is right, each list produced by its own history of human decisions.

The Hebrew Bible’s story is similar in shape: composed over many centuries, circulating in multiple text forms, with its final boundaries emerging gradually in the centuries around the turn of the era, and with the Samaritan community accepting only the first five books to this day. And the pattern isn’t limited to the Bible: the Quran’s standard text was fixed by a caliph’s decision, and Buddhism maintains three major canons that don’t match.

What Would We Expect to See?

If a divine being had authored certain books and wanted humanity to know which ones, the natural expectation would be a clear, early, universal list. What history shows instead is centuries of open debate, criteria applied by councils and bishops, books drifting in and out of favor, and different branches of the same faith holding different Bibles seventeen centuries later.

None of that tells us the books are worthless; many are moving, wise, and historically precious. It tells us something narrower and important: the label “scripture” wasn’t found inside the books. It was placed on them, by people, and different people placed it differently. Anyone weighing the claim that a particular collection is the complete and exclusive word of God deserves to know that the collection itself was assembled the human way.
