Who Decided the New Testament Canon? (6 of 6)

Nobody decided it in the sense the question implies.

The first appearance of exactly our twenty-seven books is in a pastoral letter announcing the date of Easter. The councils that get blamed for the canon met thirty years after that, in North Africa, and they ratified what was already being read.

Did Constantine Create the Bible?

He funded a production run. That is a different thing and the distinction is worth getting exactly right.

In AD 332 Constantine ordered fifty copies of the Scriptures from Eusebius, to be produced by skilled scribes at imperial expense for the churches of his new capital. Eusebius records the commission and reports that it was carried out.

Here is what that does not tell us. Not one of the fifty has ever been identified. We do not know what those volumes contained. Eusebius as the overseer presumably determined the contents, and it is not even clear that a particular table of contents was specified in the order.

So the honest version is narrower than either the popular claim or the popular rebuttal. The empire was now paying for Scripture production while the edges of the list were still being settled. Mass production does not by itself demonstrate a fixed canon, and any attempt to connect these fifty to surviving manuscripts is speculation.

What is certainly false is the claim that Constantine chose the books. There is no evidence of any such decision, and the canon lists both before and after him do not move in ways that would suggest imperial intervention.

What Was the First List of Twenty-Seven Books?

The thirty-ninth festal letter of Athanasius, bishop of Alexandria, in AD 367.

Festal letters were the annual announcement of the date of Easter, sent out to the churches under a bishop’s care, and they usually carried pastoral instruction alongside. In this one Athanasius lists the books of the Old and New Testaments, and his New Testament list is exactly the twenty-seven we have.

It is the first time that precise list appears anywhere.

The man matters to the story. Athanasius had been a deacon at Nicaea in 325, spent decades as bishop of Alexandria, and was exiled five separate times over the Arian controversy. This is not a bureaucrat ratifying a consensus. It is a combative and much-persecuted bishop telling his churches what they should read.

Did a Council Decide the Canon?

Councils affirmed it, later, and regionally.

The Council of Hippo in 393 appears to be the first church council to set the limits of the canon, and its statement was repeated as a canon of the Third Council of Carthage in 397. The resolution was that nothing should be read in church as divine Scripture except the canonical writings, and the list given is the familiar one: four Gospels, Acts, thirteen letters of Paul with Hebrews counted separately, the Catholic epistles, and Revelation.

Note three things about that. These were regional North African councils, not ecumenical ones. They came a generation after Athanasius’s letter. And their language is about what may be read in church, which is a ruling on practice rather than an act of creation.

The order of operations is the whole point. By the time anyone voted, the question had been answered in the churches’ lecterns for a long time.

Why Did It Take Until 367?

Because the disputed books were genuinely disputed and the process was slow.

The core was never in question. The four Gospels, Acts, Paul’s letters, 1 Peter and 1 John were being used everywhere from very early. What took time were the smaller and harder items: James, Jude, 2 Peter, 2 and 3 John, and in some regions Hebrews and Revelation.

Those took time because the criteria were being applied seriously. A short letter by a minor figure, quoting a book outside the canon, does not get waved through. Jude took centuries to settle for exactly that reason.

The slowness is evidence of care rather than of confusion.

What Actually Decided It?

Use, across a wide geography, over three centuries, tested against a small number of criteria.

Apostolic connection. Widespread reception rather than local enthusiasm. Consistency with the teaching the churches recognised as their own. And antiquity, which quietly disqualified most of the alternatives on its own.

No single person applied those. They were applied by hundreds of congregations deciding what to read aloud on Sunday, over a very long time, and the lists that eventually got written down were describing the outcome.

The question opens with Marcion in 144 and closes with Athanasius in 367. Two hundred and twenty-three years, no smoke-filled room, and a paper trail the whole way.

What happened next, once the list was settled and the text had to be translated, is the story of Jerome going back to the Hebrew.

Where the sourcing stops: the four criteria are a standard summary of how the canon settled rather than a formal list published in that form by any ancient source. The judgment that slowness on the disputed books indicates care rather than confusion is my own reading.

Footnotes

1. The Constantine claim is worth correcting carefully rather than dismissively, because the commission is real. Fifty imperially funded Bibles is a significant fact about the fourth century. What it is not is evidence about who chose the contents, and the gap between those two statements is where most of the popular argument lives.
2. That the councils use the language of what may be read in church rather than what is Scripture is easy to miss and it matters. They are regulating a practice that already existed. A body creating a canon would not phrase its ruling as a restriction on public reading.
