Author of the Book of Acts

Author of the Book of Acts

The Book of Acts serves as a direct sequel to the Gospel of Luke, and both are traditionally believed to be written by the same author. Although neither book explicitly names its writer, both are addressed to a figure named Theophilus (Luke 1:1-4; Acts 1:1-2). The use of the honorific “most excellent” suggests that Theophilus was likely a Roman official or someone of high social standing, though little else is known about him, and he does not appear elsewhere in Scripture.

Scholars have long noted striking similarities between Luke and Acts in terms of theology, writing style, and vocabulary. This has led to the strong tradition that Luke—the physician and companion of the Apostle Paul—is the author of both works. Luke’s firsthand experience traveling with Paul would explain the detailed knowledge of Paul’s missionary journeys found in Acts. Additionally, the presence of medical observations and terminology throughout these texts further supports the attribution to Luke, a trained physician (Colossians 4:14; Philemon 1:24).

Despite these compelling factors, definitive proof of Luke’s authorship remains elusive. Nonetheless, the combined evidence of literary style, thematic continuity, and historical context makes Luke the most plausible candidate for authoring both the Gospel of Luke and the Acts of the Apostles.
