Which Letters Did Paul Really Write?
I, Tertius, who write the letter, greet you in the Lord.Romans 16:22 · World English Bible
Original Language & Text
Scholars analyze vocabulary, sentence structure, and theological emphasis across the thirteen letters bearing Paul's name. The 'undisputed' letters share overlapping vocabulary and rhetorical style (diatribe form, argumentative structure), while letters like the Pastorals (1-2 Timothy, Titus) contain a notably higher proportion of words not found elsewhere in Paul (hapax legomena) and Greek style some describe as more polished but less argumentatively dense. Ephesians shares much vocabulary with Colossians but uses key terms differently (e.g., 'mystery,' 'church' as universal body rather than local congregation). Ancient letter-writing commonly used an amanuensis (secretary)—Romans 16:22 names Tertius as the actual scribe, and Paul's mention of signing 'with my own hand' (Galatians 6:11, 2 Thessalonians 3:17, Colossians 4:18) shows secretaries could shape wording while the named author dictated content, complicating simple style-based authorship judgments.
Key Terms in the Original Language
“apostle, one sent out” — used in the opening line of nearly every Pauline letter
Paul's letters consistently open by asserting his own apostolic authority; the disputed letters, the Pastorals above all, use this self-identification in ways some scholars find stylistically different from the undisputed letters, feeding the pseudonymity debate.
“with [my own] hand” (Gal. 6:11, 2 Thess. 3:17)
Paul says his own handwriting is “the sign of genuineness in every letter” (2 Thess. 3:17) — evidence he was already worried about forged letters circulating under his name, which cuts both ways: it shows Paul guarded against pseudonymity, but also confirms the practice existed for scholars to weigh when assessing the disputed letters.
History & Authorship
Ferdinand Christian Baur and the 19th-century Tubingen school first subjected the Pauline corpus to systematic historical criticism, initially accepting only four letters (Romans, 1-2 Corinthians, Galatians) as certainly authentic. Subsequent scholarship expanded the 'undisputed' list to seven (adding Philippians, 1 Thessalonians, and Philemon), a rough consensus reached by the mid-20th century and still standard in most critical introductions. Debate over the remaining six—Ephesians, Colossians, 2 Thessalonians, and the Pastoral Epistles (1-2 Timothy, Titus)—has continued for over a century, informed by vocabulary statistics, theological development arguments (e.g., a more developed church hierarchy in the Pastorals fitting a later period), and comparison to known pseudepigraphic practices in antiquity, where writing in a revered figure's name to honor or extend their teaching was not uncommon and not always considered deceptive by ancient standards.
How This Debate Developed
-
1st–2nd c.
Universal traditional acceptance
The early church accepts all thirteen letters bearing Paul's name as genuinely his.
-
1830s–40s
The Tübingen School
F. C. Baur and colleagues begin systematically questioning the authenticity of several Pauline letters.
-
19th–20th c.
Seven vs. six letters
Critical scholarship converges on seven “undisputed” letters and six more commonly “disputed” ones, a split that still structures the debate.
The Popular / Mainstream View
The traditional and still most widely held view among churchgoers and many conservative scholars is that Paul personally wrote, or directly dictated, all thirteen letters attributed to him in the New Testament, including Ephesians, Colossians, 2 Thessalonians, and the Pastoral Epistles (1-2 Timothy, Titus). Differences in style and vocabulary are attributed to Paul's use of different secretaries (amanuenses), his addressing different audiences and circumstances, and natural development in his thinking or vocabulary over the course of his ministry and imprisonment.
Minority & Alternative Views
Seven undisputed letters
Critical scholarship broadly agrees that Romans, 1 Corinthians, 2 Corinthians, Galatians, Philippians, 1 Thessalonians, and Philemon were genuinely written by Paul, based on consistent style, coherent biographical details, and theological continuity. This 'seven-letter' consensus is the closest thing to firm scholarly agreement in this field.
Disputed 'Deutero-Pauline' letters
Ephesians, Colossians, and 2 Thessalonians are considered by many, though not all, critical scholars to be written by later followers of Paul in his name, citing stylistic differences, theological shifts (a more cosmic Christology in Ephesians/Colossians), and, for 2 Thessalonians, tension with 1 Thessalonians over the timing of Christ's return.
Pseudonymous Pastoral Epistles
A majority of historical-critical scholars consider 1-2 Timothy and Titus pseudonymous, written in Paul's name by a later follower, likely in the late 1st or early 2nd century, pointing to their vocabulary (many words absent from the undisputed letters), their assumption of a more developed church hierarchy (bishops, deacons), and their concern with combating specific 2nd-century heresies.
What Scholars Say
There is near-consensus among historical-critical scholars that the seven letters (Romans, 1-2 Corinthians, Galatians, Philippians, 1 Thessalonians, Philemon) are authentically Pauline. There is a strong majority view, though not unanimous, that the Pastoral Epistles are pseudonymous, written after Paul's death. Ephesians, Colossians, and 2 Thessalonians occupy a genuinely contested middle ground, with capable scholars defending authenticity on each side. Confessional and many conservative scholars maintain full Pauline authorship of all thirteen letters, noting that stylometric and theological-development arguments are probabilistic, not conclusive.
