The book of Acts, also known as the Acts of the Apostles, was written by Luke, the same author of the Gospel of Luke. Luke was a physician and a companion of Paul the Apostle. Acts is considered a sequel to the Gospel of Luke and together they form a two-volume work often referred to as Luke-Acts.
Luke wrote Acts to document the early church’s birth and growth, starting with Jesus' resurrection and ending with Paul in Rome. The book vividly shows the spread of the gospel through the work of the Holy Spirit among Jews, Samaritans, and Gentiles.
There are linguistic, theological, and stylistic similarities between Luke and Acts, and both are addressed to the same person named Theophilus, which strongly supports their common authorship. Additionally, the "we" passages in Acts suggest the author traveled with Paul during parts of his missionary journeys, consistent with Luke’s role as Paul’s companion.
Traditionally and historically, the early church unanimously attributed Acts to Luke, and modern scholarship still widely accepts this as the most plausible authorship, despite some debates on details and historical exactness.
In summary, Luke, the physician and companion of Paul, wrote the Acts of the Apostles.
