The 13 Pauline epistles
A contextual guide to the letters traditionally linked with Paul, their early circulation, literary form and the continuing discussion about authorship.
Letters, communities and interpretation
This essay summarizes historical and theological approaches without asking readers to adopt one position.
An “epistle” is a literary letter intended for circulation beyond a private exchange. The writings traditionally associated with Paul appear to have arisen from correspondence with early Christian communities and individuals, often addressing local questions, teaching and community organization.
Over time, copies were shared among churches and read in public worship. By the late first and early second centuries, Christian writers were aware of collections of Pauline letters. These writings eventually became part of the New Testament canon, although the process differed among communities and regions.
How the letters are structured
Ancient writers sometimes dictated to secretaries or relied on assistants who helped prepare a text. Pauline letters commonly open by identifying the sender and recipients, followed by thanksgiving or prayer. They then develop instruction, argument or pastoral guidance before closing with personal greetings and a blessing.
The apparent unity of some letters is also discussed. For example, scholars have proposed that Romans 16, 1 Corinthians, 2 Corinthians and Philippians may preserve material from more than one stage of correspondence. These proposals remain matters of interpretation rather than universally accepted conclusions.
The traditional collection
The thirteen letters conventionally connected with Paul are Romans; 1 and 2 Corinthians; Galatians; Ephesians; Philippians; Colossians; 1 and 2 Thessalonians; 1 and 2 Timothy; Titus; and Philemon. Hebrews is included in some historical discussions of Pauline collections but is not one of the thirteen letters that names Paul as its author.
Second-century collections demonstrate that different Christian groups made different decisions about which writings to read and preserve. Later canonical collections brought the familiar set together, while debates about authority and authorship continued.
Who wrote the epistles?
Christian interpreters do not all answer this question in the same way. Some accept the traditional attribution of all thirteen letters. Others distinguish between letters widely regarded as authentically Pauline and letters that may have been written by later followers working within Paul’s theological tradition.
- Letters most often regarded as authentically Pauline: Romans, 1 and 2 Corinthians, Galatians, Philippians, 1 Thessalonians and Philemon.
- Letters whose authorship is debated: Colossians, Ephesians and 2 Thessalonians.
- Pastoral letters: 1 Timothy, 2 Timothy and Titus, which many critical scholars place later than Paul’s lifetime.
These categories summarize influential scholarly patterns rather than a single formal consensus. Conservative, historical-critical and other Christian approaches may use different standards when weighing the internal claims of a letter, its vocabulary, its theology and the circumstances it appears to address.
A comparison of approaches
| Letter or group | Traditional attribution | Common historical-critical assessment | Main questions |
|---|---|---|---|
| Romans, 1–2 Corinthians, Galatians, Philippians, 1 Thessalonians, Philemon | Paul | Often treated as the core Pauline letters | Context, chronology and the development of Paul’s argument |
| Colossians | Paul | Authorship remains debated | Vocabulary, theology and relationship to other letters |
| Ephesians | Paul | Often attributed to a later Pauline writer | Style, ecclesiology and dependence on earlier material |
| 2 Thessalonians | Paul | Debated | Apocalyptic teaching and differences of style |
| 1–2 Timothy and Titus | Paul | Frequently considered later compositions | Church organization, vocabulary and historical setting |
Dates and authorship judgments are approximate. Ancient texts rarely provide the kind of independent documentation expected by modern historical research.
Why authorship matters
Authorship affects how readers understand a letter’s historical setting, authority and relationship to Paul’s earliest communities. It can also shape interpretations of teachings about leadership, community life, gender and relations with wider society. Responsible study distinguishes what a text says from the later conclusions drawn from its attribution.
Some ancient literary cultures allowed a student or follower to write in the name of a respected teacher. Modern readers may evaluate that practice differently, so it is useful to avoid applying one ethical category without first considering the historical setting.

Questions about this essay
Are all thirteen letters considered written by Paul?
No. Some Christian traditions accept the traditional attribution of all thirteen, while many historians and biblical scholars distinguish between letters they consider strongly Pauline and letters whose authorship is debated.
Why is Hebrews not listed among the thirteen?
Hebrews does not identify Paul as its author. It has sometimes been discussed alongside Pauline writings because of its place in certain historical collections, but it is not one of the thirteen letters traditionally bearing Paul’s name.
Does “pseudonymous” always mean the same thing as a modern forgery?
No. The term describes a text presented under the name of another person, but ancient literary conventions and modern judgments about authorship are not identical. Historical context is essential.
Why do scholars compare vocabulary and style?
Vocabulary, sentence structure, theological emphasis and references to historical circumstances can help researchers compare letters and assess whether they may come from the same author or period.
Can this page settle the authorship debate?
No. It presents major approaches and explains the evidence commonly discussed. Readers should consult specialist introductions and commentaries for fuller treatment.
