How We Got the Bible
The Bible didn't arrive as a finished set. Each tradition's list of authoritative books — its canon — came together gradually, through centuries of use, debate, and, eventually, formal decision. The chart below covers the ancient formation period: the Hebrew Bible's three sections closing in turn, then the New Testament's slower path from competing early lists to a settled 27 books.

Why the Canons Still Don't Match
Nothing shown above changed for roughly a thousand years afterward — Jerome's Vulgate, deuterocanonical books included, was simply the Bible used in the Western church. The split reopened during the Reformation. Martin Luther's German translation (1534) set several Old Testament books apart in their own section, calling them “profitable and good to read” but not authoritative for doctrine — partly because some of them (2 Maccabees especially, on prayer for the dead) were used to support Catholic teachings Luther rejected. The Catholic Church responded at the Council of Trent (1546), formally dogmatizing the wider canon it had already been using since the 4th century, by a vote of 24 to 15 with 16 abstentions. Protestant confessions then codified the exclusion in the other direction — the Westminster Confession (1647) explicitly denies the Apocrypha the status of Scripture. Eastern Orthodox and Ethiopian Orthodox churches, which trace their Old Testament to the older Greek Septuagint through continuous use rather than a single defining council, kept wider Old Testaments still today — the Ethiopian canon wider still, with Enoch and Jubilees included nowhere else.
The New Testament had its own regional variation, on a smaller scale: the Syriac-speaking churches' Peshitta originally excluded 2 Peter, 2 and 3 John, Jude, and Revelation, and some Eastern churches still treat those five books with less liturgical weight than the rest of the New Testament.
What's in Each Old Testament
These books (the deuterocanon, or Apocrypha) exist in every tradition's manuscript history — the disagreement is about which of them count as Scripture.

Worth Knowing, Event by Event
Dating disputes, sourcing caveats, and background on individual entries in the chart above — also available by hovering any mark.
Torah accepted as authoritative (450 BC) — By the time of Ezra's public reading of the Law (Nehemiah 8), traditionally dated around 450 BC.
Prophets (Nevi'im) section closes (250–180 BC) — By 132 BC, the Greek prologue to Sirach already refers to “the Law, the Prophets, and the other books” as a known, fixed collection.
Septuagint translation (250–100 BC) — The Torah was translated to Greek first, traditionally under Ptolemy II; the rest of the Hebrew Bible followed over the next century or so.
Dead Sea Scrolls community active (250 BC – AD 70) — Manuscripts from Qumran show real textual diversity before any single Hebrew text became standard.
Writings (Ketuvim) substantially settled (AD 70–100) — Often linked to a supposed “Council of Jamnia” (c. AD 90) — most scholars today doubt any such formal council fixed the canon; a few books (Ecclesiastes, Song of Songs) were still debated among rabbis into the 2nd century.
Marcion's canon (AD 140) — An edited Luke and ten Pauline letters, with the Old Testament rejected outright — the first attempt at a Christian canon, and the jolt that pushed the wider church to define its own.
Muratorian fragment (AD 170–200) — Traditionally dated to the late 2nd century as the earliest surviving list resembling the later New Testament; a minority of scholars (Sundberg, Hahneman) argue it's actually 4th-century.
Origen's threefold categories (AD 230) — Sorted books into accepted, disputed, and rejected — Hebrews, James, 2 Peter, 2–3 John, Jude, and Revelation were among the disputed.
Athanasius's 39th Festal Letter (AD 367) — The first surviving list naming exactly the 27 books of today's New Testament, no more and no less.
Jerome's Vulgate translation (AD 382–405) — Jerome favored the shorter Hebrew canon (“veritas hebraica”) and was skeptical of the deuterocanonical books, but translated them anyway for completeness — a tension the Western church didn't fully resolve for another thousand years.
Council of Carthage (AD 397) — Reaffirmed again in 419.
