Why do descriptions of Paul’s missionary journeys in Acts contain geographical errors?

1. Overview of Paul’s Missionary Journeys

Paul’s extensive travels, recorded primarily in the Book of Acts, spanned multiple regions—from the eastern Mediterranean across Asia Minor and into Europe. Acts details at least three principal missionary journeys (Acts 13–21), concluding with Paul’s eventual voyage to Rome (Acts 27–28). These journeys involved numerous cities, cultures, and geographical landmarks, leading some readers to question certain place names or route descriptions.

Despite claims that Acts contains geographical inaccuracies, extensive study and corroboration reveal that the text remains historically credible. By understanding the language, cultural context, and shifts in regional nomenclature, one finds a coherent account consistent with known first-century geography.

2. Common Allegations of Geographical "Errors"

Critics sometimes propose that Luke, the author of Acts, made errors in naming or describing particular locales. Examples include concerns about how certain provinces are labeled (e.g., depictions of Phrygia and Galatia in Acts 16:6), or puzzlement over city statuses (e.g., Philippi in Acts 16:12 being called “a leading city of that district of Macedonia” [BSB]).

Additionally, questions arise about the exact route Paul and his companions took in some passages, as well as whether the text confuses city boundaries. Such concerns are often rooted in historical shifts—provinces changed names or official jurisdictional lines—and in the Greek language conventions that Luke employed.

3. Contextual Considerations

The first century was marked by rapidly changing political and administrative lines. What might be called “Galatia” earlier could gain or lose territory, and a certain city could be identified with a region differently, depending on the era.

Luke’s account relies on local terms for political areas and titles of magistrates. This precision is now well supported by inscriptions and archaeological findings, demonstrating that Luke used terminology appropriate to the time and place he described. Therefore, modern readers encountering region names that differ from their current or later designations might interpret inaccuracy, when in fact it reflects an authentic historical background.

4. Luke’s Sources and Literary Conventions

Luke’s prologue (Luke 1:1–4) in the companion Gospel underscores his intention to compile a thoroughly investigated account. Acts follows the same method. Luke includes details gathered from eyewitnesses and his own participation in certain journeys (the “we” passages in Acts, such as Acts 16:10–17).

Moreover, literary conventions of the day did not always require the detailed step-by-step travel logs we might expect in contemporary historical writing. Instead, ancient texts offered summaries or thematic groupings of events, all while employing idiomatic expressions to denote travel between regions. Such stylistic components sometimes strike modern readers as uncertain or incomplete, yet they align with known ancient practices for recording history.

5. Archaeological and Historical Corroborations

Numerous archaeological discoveries and historical records shed light on the places Paul visited:

• Gallio Inscription at Delphi: Confirms the dating of Paul’s visit to Corinth (Acts 18:12–17). The inscription verifies the presence of Gallio in Corinth around AD 51–52, aligning with the scriptural timeline.

• City Officials in Thessalonica (Acts 17:6): Scholars long questioned Luke’s use of the term “politarchs.” However, inscriptions unearthed in northern Greece confirm that this exact term was used for the local magistrates of Thessalonica.

• Philippi’s Status (Acts 16:12): The city is referred to as a Roman colony and “a leading city of that district of Macedonia.” Inscriptions and historical records confirm Philippi’s designation as a Roman colony (Colonia Augusta Julia Philippensis), clarifying Luke’s accurate terminology for its civic rank.

Such corroborations illustrate that Luke’s writing corresponds to first-century realities, reinforcing the view that alleged “errors” actually stem from misunderstandings of historical and cultural contexts.

6. Possible Explanations for Perceived Discrepancies

Alleged discrepancies are more accurately explained by:

1. Regional Renaming: Boundaries of Asia Minor, Macedonia, and other regions shifted repeatedly under Roman administrative changes. Terms like “Pisidia” or “Galatia” can apply differently depending on the ruler and era.

2. Local Dialects and Language Nuances: Greek expressions identifying towns or provinces might differ from official Latin designations. Luke, writing for a Greek-speaking audience, used the nomenclature naturally recognized by that audience.

3. Condensed Travel Logs: Acts often summarizes events and does not necessarily detail every stop or timeline segment (Acts 20:2 compresses a large region into a few words). These summaries can lead critics to assume errors where the text is instead offering a succinct overview.

7. Reliability of the Author’s Method

Luke conducts his account with notable care. The Gospel of Luke and the Book of Acts repeatedly showcase a knowledge of seafaring terms, provincial leadership titles, and local customs:

• In Acts 27, Luke painstakingly describes nautical details consistent with the maritime practices of the era.

• Throughout Acts, he accurately identifies proconsuls, such as Sergius Paulus in Cyprus (Acts 13:7), matching the precise civic designation for that island’s Roman governance.

These points confirm Luke’s consistency in historical detail, even when compressed narratives might appear to create confusion for modern readers. Instead of dwelling on quick references as errors, readers can compare them with archaeological and textual evidence, discovering remarkable alignment.

8. Scripture’s Internal Consistency

Acts seamlessly intertwines with Paul’s own letters. For instance, references to Paul’s work in Galatia (cf. Galatians 1:21–24) align with the initial journey to that region noted in Acts 13–14. Similarly, 2 Corinthians 11:25–26 reflects trials and travels that mirror the events described in Acts. These consistent internal references demonstrate coherence rather than contradiction.

This internal harmony supports the thesis that perceived geographical mistakes are actually a result of unfamiliar cultural contexts, shifting prefectural boundaries, or condensed storytelling techniques. When comprehensively examined, the Book of Acts presents a unified picture matching Paul’s epistles and the best external historical data.

9. Broader Implications for Historical Trustworthiness

Because Acts aligns with archaeological and epigraphic findings, the text stands as a remarkable historical account. Early church fathers recognized Luke’s writings as a reliable record of the events surrounding the missionary expansions of the first century. Examples such as Irenaeus referencing the continuity of Acts confirm its early adoption as an authoritative resource.

Modern scholarship finds that where the authors of the New Testament can be tested, they prove accurate. Such verification extends beyond the journeys of Paul to include mention of local customs, regional rulerships, and even the cultural tension that shaped the evolution of early Christian communities.

10. Conclusion

Descriptions of Paul’s missionary journeys in Acts may appear to contain geographical errors when viewed without attention to first-century naming conventions and the fluid nature of provincial boundaries. However, careful scholarship, archaeological corroboration, and historical records show that criticisms generally rest on misunderstandings rather than genuine mistakes.

Luke’s skilled narration reveals a consistent, well-researched document that harmonizes with known data from both ancient texts and modern discoveries. Within this context, those who explore the Book of Acts carefully find a faithful depiction of actual events, accurately described places, and trustworthy details of Paul’s extensive travels. As Acts 16:12 states regarding Philippi, “a leading city of that district of Macedonia,” Luke’s account, time and again, proves historically and topographically well-founded.
