The first book of the New Testament was not Matthew, Mark, Luke, or John. Scholars date Paul’s first letter to the Thessalonians to approximately 50-51 CE — roughly 15 years before the earliest Gospel was composed. Paul was writing theology, pastoral instruction, and community guidance to scattered congregations across the Roman Empire before anyone had set down a narrative account of Jesus’s life and ministry. The canonical order of the New Testament, which places the four Gospels first, reflects theological priority rather than historical sequence.
That gap between canonical order and composition order shapes how readers understand the entire New Testament. What follows is the complete list of all 27 books as they appear in most Bibles, alongside the approximate dates when scholars believe they were composed.
The 27 Books in Canonical Order
The New Testament is arranged in four major groupings: the Gospels and Acts, Paul’s letters (roughly longest to shortest), the General Epistles, and Revelation. This arrangement creates a narrative flow from the life of Jesus, through the expansion of the early church, to theological instruction, and finally to apocalyptic vision.
| # | Book | Canonical Section | Approx. Composition |
|---|---|---|---|
| 1 | Matthew | Gospels | ~80-90 CE |
| 2 | Mark | Gospels | ~65-70 CE |
| 3 | Luke | Gospels | ~80-90 CE |
| 4 | John | Gospels | ~90-100 CE |
| 5 | Acts | History | ~80-90 CE |
| 6 | Romans | Pauline Letters | ~55-58 CE |
| 7 | 1 Corinthians | Pauline Letters | ~53-55 CE |
| 8 | 2 Corinthians | Pauline Letters | ~55-56 CE |
| 9 | Galatians | Pauline Letters | ~50-55 CE |
| 10 | Ephesians | Pauline Letters | ~80-90 CE |
| 11 | Philippians | Pauline Letters | ~54-62 CE |
| 12 | Colossians | Pauline Letters | ~60-80 CE |
| 13 | 1 Thessalonians | Pauline Letters | ~50-51 CE |
| 14 | 2 Thessalonians | Pauline Letters | ~51-52 or ~80-100 CE |
| 15 | 1 Timothy | Pastoral Letters | ~90-110 CE |
| 16 | 2 Timothy | Pastoral Letters | ~90-110 CE |
| 17 | Titus | Pastoral Letters | ~90-110 CE |
| 18 | Philemon | Pauline Letters | ~54-62 CE |
| 19 | Hebrews | General Epistles | ~60-90 CE |
| 20 | James | General Epistles | ~60-100 CE |
| 21 | 1 Peter | General Epistles | ~70-90 CE |
| 22 | 2 Peter | General Epistles | ~100-150 CE |
| 23 | 1 John | General Epistles | ~85-100 CE |
| 24 | 2 John | General Epistles | ~85-100 CE |
| 25 | 3 John | General Epistles | ~85-100 CE |
| 26 | Jude | General Epistles | ~65-90 CE |
| 27 | Revelation | Apocalyptic | ~90-95 CE |
Several things emerge from the composition dates. First, the Pauline letters cluster in the 50s CE — a full generation before the Gospels. Second, the Gospels themselves were composed across roughly 35 years, from Mark (~65-70 CE) to John (~90-100 CE), with each author writing for different communities in different circumstances. Third, the latest New Testament texts — 2 Peter, the Pastoral Letters — date to the early 2nd century CE, more than a generation after the earliest.
Paul Before the Gospels
The most significant insight from composition-order reading is that Paul’s undisputed letters (1 Thessalonians, Galatians, 1-2 Corinthians, Romans, Philippians, Philemon) are the earliest Christian documents. They predate every Gospel, every account of Jesus’s birth, death, or resurrection as a narrative, and every description of his earthly ministry.
Paul’s letters contain no birth narrative. No Sermon on the Mount. No parables. No accounts of specific miracles beyond a few passing references. Paul writes about the risen Christ, the meaning of the crucifixion, and the community of believers — but he does so without the biographical framework that the Gospel writers would later construct.
This is not because Paul was unaware of Jesus’s life. It is because Paul was writing letters to specific churches about specific problems, and his theological framework did not depend on biographical detail in the way the Gospels would. Dale Martin, in his Yale course on the New Testament, notes that reading Paul first — as composition order requires — means encountering early Christian theology on its own terms, before the Gospel narratives provide the context modern readers typically assume.
The canonical order reverses this relationship. By placing the Gospels first, it creates an impression that Paul is commenting on a story the reader already knows. In composition order, Paul comes first, and the Gospels appear as later literary works that give narrative shape to traditions Paul knew in a different form.
Seven Undisputed, Six Debated
Not all letters attributed to Paul were composed by him. Scholars distinguish between Paul’s seven undisputed letters — Romans, 1 Corinthians, 2 Corinthians, Galatians, Philippians, 1 Thessalonians, and Philemon — and six letters whose authorship is debated or widely considered pseudepigraphic (composed in Paul’s name after his death).
The debated letters include Ephesians, Colossians, and 2 Thessalonians, which scholars assess on a spectrum from “possibly Paul” to “probably not.” The Pastoral Letters — 1 Timothy, 2 Timothy, and Titus — are considered pseudepigraphic by the majority of New Testament scholars. Bart D. Ehrman has noted that pseudepigraphy (writing under another’s name) was a recognized literary practice in the ancient world, not necessarily an attempt to deceive.
The canonical order intermingles undisputed and disputed letters without distinction. Romans, 1 Corinthians, and Galatians sit alongside Ephesians and the Pastorals as though they share the same author and historical moment. Composition-order reading separates them by decades, making the theological development between genuine Paul (~50-62 CE) and the Pastoral Letters (~90-110 CE) visible.
The Gospels as Late First-Century Literature
The four Gospels — Matthew, Mark, Luke, and John — were composed between approximately 65 and 100 CE, roughly 35 to 70 years after the events they describe. Most scholars consider the Gospels originally anonymous; the names Matthew, Mark, Luke, and John were attributed by later tradition, likely in the 2nd century CE.
The compositional relationship among the first three Gospels (the “Synoptic Gospels”) is one of the most studied questions in New Testament scholarship. The dominant scholarly model, the Two-Source Hypothesis, proposes that the Gospel of Mark was composed first (~65-70 CE), and that the authors of Matthew and Luke independently used Mark as a source, along with a hypothetical sayings collection called Q (from the German Quelle, meaning “source”). Raymond E. Brown, in his Introduction to the New Testament, described this literary relationship as one of the most well-established findings in biblical scholarship.
The Gospel of John (~90-100 CE) follows a substantially different structure, chronology, and theological emphasis. Where the Synoptics share extensive material in similar order, John contains material found in no other Gospel — the raising of Lazarus, the wedding at Cana, extended theological discourses — and omits events central to the Synoptic accounts.
The canonical order places the Gospels first as theological foundation. Uncanon uses compositional order — arranging texts by when scholars believe they were composed, beginning with Paul’s earliest letters. This reveals how early Christian thought developed before the Gospel narratives took shape. Explore the compositional approach.
The Disputed and the Late
The latest texts in the New Testament — 2 Peter (~100-150 CE), the Pastoral Letters (~90-110 CE), Jude, 2-3 John — are also among the most disputed in terms of authorship. Several of these books remained contested well into the 4th century CE. Eusebius of Caesarea, writing around 325 CE, categorized New Testament texts as “recognized,” “disputed,” and “rejected.” His “disputed” category included James, Jude, 2 Peter, and 2-3 John — books that eventually made the canon but whose inclusion was not a foregone conclusion.
The path from scattered community texts to a fixed 27-book collection took centuries. Athanasius’s Easter letter of 367 CE is the earliest known list matching the modern New Testament canon exactly. The regional councils at Hippo (393 CE) and Carthage (397 CE) ratified similar lists. But these councils recognized what communities had largely already been practicing rather than imposing a new standard.
