who wrote acts in the bible

The Book of Acts in the Bible is traditionally attributed to Luke , the same person to whom the Gospel of Luke is ascribed, but modern scholars note that the book itself is formally anonymous and there is debate about its precise authorship and date.

Traditional Christian View

Most Christian traditions hold that Acts was written by Luke, a physician and companion of the apostle Paul.

This view rests on early church testimony (writers like Irenaeus, Tertullian, and Eusebius) and on the strong literary and thematic link between the Gospel of Luke and Acts, which together form a two‑volume work often called “Luke–Acts.”

Internal Clues in Acts

Acts is addressed to the same figure, Theophilus, as the Gospel of Luke, and Acts 1:1 refers back to a “former book,” which most interpreters identify as Luke’s Gospel.

So‑called “we‑passages” in Acts (sections where the narrative shifts to “we”) suggest the author sometimes traveled with Paul, which fits the traditional picture of Luke as Paul’s co‑worker.

Scholarly Debate Today

In contemporary biblical scholarship, the traditional attribution to Luke the physician is still widely discussed but not universally accepted.

Some scholars argue that stylistic, theological, or historical features of Acts indicate a later, educated Greek Christian author using sources and shaping a theological narrative, rather than a simple travel companion of Paul, and a minority propose alternative or unknown authors.

When and Where It Was Written

Many conservative and traditional sources suggest Acts was written around the early 60s CE, possibly in Rome, pointing to the narrative ending with Paul alive in Rome and not mentioning later events.

A large number of critical scholars, however, favor a date between about 80–90 CE or even into the early 2nd century, often on the basis of literary analysis and possible dependence on other historical writings.

TL;DR: In church tradition, Luke—Paul’s companion and the author of the third Gospel—wrote Acts, but the text itself is anonymous and many modern scholars simply refer to the author as the unknown writer of “Luke–Acts,” with ongoing debate about who exactly that was and when he wrote.
