Is the Book of Acts Historically Reliable? What Archaeology Shows

Why Acts Matters

If you want to test the historical reliability of the New Testament, the Book of Acts is your best laboratory. Unlike the Gospels, which primarily record teachings and events in a relatively small geographic area, Acts is a travel narrative spanning the entire eastern Mediterranean. It names specific cities, specific officials with specific titles, specific customs, and specific geographic details — all of which can be checked against the archaeological and historical record.

And when scholars have checked, the results have been remarkable.

Colin Hemer’s 84 Confirmed Details

The late Cambridge scholar Colin Hemer spent years meticulously cataloging historically verifiable details in Acts chapters 13–28. In his magisterial 1989 work The Book of Acts in the Setting of Hellenistic History, he identified 84 facts that have been confirmed by historical and archaeological evidence.

These aren’t vague generalities. They include:

• Correct titles for officials — and these varied from city to city. Thessalonica had “politarchs” (a title once thought to be Luke’s invention until inscriptions confirmed it). Cyprus had a “proconsul” (confirmed by inscriptions naming the exact official, Sergius Paulus). Ephesus had a “temple warden” (neōkoros) of Artemis. Philippi was a Roman “colony.” Each title is precisely right for that specific city at that specific time.

• Accurate geographic and nautical details — the shallow coastal waters near certain ports, the direction of prevailing winds, the names of small harbors. Acts 27’s account of Paul’s shipwreck reads like a sailor’s log and has been confirmed as accurate in extraordinary detail.

• Correct local customs and practices — the right synagogue practices for each city, the proper legal procedures in different jurisdictions, even the correct local deities worshipped in specific locations (Zeus and Hermes at Lystra, for instance).

What makes this significant is that many of these details would have been nearly impossible to get right without firsthand knowledge. Ancient political titles changed frequently — a city might shift from having a “proconsul” to a “propraetor” within a few years. Getting dozens of these right, across a wide geographic range, points strongly to a careful, well-informed author writing close to the events.

Luke as Historian

The author of Acts (traditionally identified as Luke, Paul’s traveling companion) has been evaluated against the standards of ancient historiography — and he holds up remarkably well.

Craig Keener, whose four-volume commentary on Acts runs to over 4,000 pages, places Luke squarely in the tradition of the best ancient historians. Keener notes that Luke’s accuracy with incidental details is comparable to that of Thucydides and Polybius — historians universally respected by classicists.

Ben Witherington III argues that Luke demonstrates the characteristics of a careful, research-oriented historian: he names his sources, acknowledges his methodology (Luke 1:1–4), and gets verifiable details right with striking consistency.

The great classical historian Sir William Ramsay began his career skeptical of Acts, assuming it was a second-century fabrication. After years of archaeological fieldwork in Asia Minor, he concluded that Luke was “a historian of the first rank,” whose statements could be trusted even in the smallest details.

Why This Matters for the Big Picture

Here’s the point that critics often miss: if Luke is demonstrably accurate on dozens of verifiable historical details — details that a later forger would almost certainly have gotten wrong — this gives us strong reason to take seriously his accounts of events we can’t independently verify, including miracles and the resurrection appearances.

This isn’t blind faith. It’s the same logic historians use everywhere else. If a source proves reliable on checkable facts, you give it the benefit of the doubt on uncheckable ones — unless you have specific reason not to.

No ancient document is above scrutiny. But Acts has survived more scrutiny than almost any other ancient text and emerged with its credibility not just intact but strengthened. The 84 confirmed details aren’t just trivia — they’re evidence that the earliest Christian movement was grounded in real history, told by people who were actually there.

When archaeology keeps saying “Luke got it right,” it’s worth asking: what else did he get right?
