Who Wrote 1 Thessalonians?
Quick Summary
The First Letter to the Thessalonians is widely regarded as one of the earliest writings of the New Testament and is almost universally accepted as written by the apostle Paul. Internal evidence, early church testimony, and modern scholarship converge to affirm Pauline authorship. The letter reflects Paul’s missionary activity, pastoral concern, and theological priorities during the earliest period of the Christian movement.
Introduction
First Thessalonians occupies a unique place in the New Testament. Often dated earlier than the Gospels, the letter offers a window into the earliest Christian communities and the formative years of apostolic teaching. Unlike some later New Testament letters, 1 Thessalonians has rarely been disputed in terms of authorship.
The question of who wrote 1 Thessalonians is therefore less controversial than for some other epistles. Nevertheless, a careful examination of the letter’s internal evidence, its reception in the early church, and modern academic analysis confirms why Pauline authorship has remained a stable conclusion across centuries of interpretation.

Internal Evidence from the Letter
First Thessalonians opens by naming its authors: Paul, Silvanus, and Timothy (1 Thessalonians 1:1). While the greeting reflects a collaborative ministry, the dominant voice throughout the letter is Paul’s. The letter consistently uses first-person plural language common in Paul’s correspondence, reflecting both pastoral solidarity and apostolic authority.
(Malherbe, The Letters to the Thessalonians, pp. 61–64)
The author refers to personal experiences that align closely with the account in Acts. He recalls having proclaimed the gospel in Thessalonica amid opposition, being forced to leave prematurely, and maintaining deep concern for the fledgling community (1 Thessalonians 2:1–12; 2:17–20).
These references correspond directly with the narrative of Paul’s ministry in Thessalonica described in Acts 17:1–9, strengthening the historical credibility of Pauline authorship.
(Malherbe, Thessalonians, pp. 67–70)
The letter also reflects Paul’s theological priorities. Themes such as holiness, perseverance under persecution, ethical instruction, and the hope of Christ’s return are consistent with Paul’s teaching elsewhere. The discussion of the parousia in 1 Thessalonians 4:13–18 reflects early Christian eschatological concern rather than later theological development.
(Moo, Thessalonians, pp. 135–140)
Historical Setting and Date
Most scholars date 1 Thessalonians to around 49–51 CE, making it one of the earliest extant Christian writings. The letter was likely written from Corinth during Paul’s second missionary journey, shortly after Timothy returned with news about the Thessalonian church.
This early date strengthens the case for Pauline authorship, as it situates the letter firmly within Paul’s lifetime and missionary activity.
(Collins, Introduction to the New Testament, pp. 312–314)
Early Church Testimony
Early Christian writers consistently attributed 1 Thessalonians to Paul. The letter is included in early collections of Pauline correspondence and is cited by church fathers without dispute.
Irenaeus refers to Paul’s instruction to the Thessalonians when discussing Christian hope and resurrection, treating the letter as authoritative apostolic teaching (Against Heresies 5.6.1).
(Irenaeus, Against Heresies 5.6.1)
Tertullian also cites 1 Thessalonians as written by Paul, particularly in discussions concerning resurrection and ethical conduct (On the Resurrection of the Flesh24).
(Tertullian, De Resurrectione Carnis 24)
Eusebius includes 1 Thessalonians among the universally recognized Pauline letters, indicating that its authorship was never seriously questioned in the early church.
(Eusebius, Ecclesiastical History 3.3.5)
Modern Scholarly Consensus
Modern New Testament scholarship overwhelmingly affirms Pauline authorship of 1 Thessalonians. The letter is routinely classified among Paul’s undisputed epistles.
Abraham J. Malherbe emphasizes the letter’s coherence with Paul’s known biography, rhetorical style, and pastoral concerns. He argues that the personal tone and historical specificity make pseudonymous authorship highly unlikely.
(Malherbe, Thessalonians, pp. 9–12)
Douglas Moo similarly notes that the convergence of internal evidence, Acts, and early church reception renders Pauline authorship the most historically responsible conclusion.
(Moo, Thessalonians, pp. 21–24)
Inspiration and Apostolic Authority
First Thessalonians demonstrates how early Christian theology developed within lived pastoral contexts. Paul writes not as a distant theologian but as a missionary shepherd addressing real fears, hopes, and questions within a young church.
The letter’s authority arises from its grounding in apostolic witness, communal experience, and faithfulness to the gospel message. Inspiration here is not abstract but deeply relational.
(Wright, Paul and the Faithfulness of God, pp. 482–486)
Conclusion
First Thessalonians identifies Paul as its primary author, reflects his missionary activity and theological concerns, and was received as Pauline from the earliest generations of the church. Internal textual evidence, early church testimony, and modern scholarship converge in strong agreement.
As one of the earliest Christian writings, 1 Thessalonians provides invaluable insight into the faith, hope, and perseverance of the first believers and stands firmly within the Pauline tradition.
