The Book of Acts, also known as the Acts of the Apostles, is traditionally believed to have been written by Luke, a physician and traveling companion of the Apostle Paul. This is supported by early Christian tradition and internal evidence within the text, such as the dedication to Theophilus, which is also found in the Gospel of Luke, indicating the same author for both books
. Luke-Acts is considered a two-part work, with the Gospel of Luke as the first volume and the Book of Acts as the second, continuing the story of Jesus' mission through the early church and the spread of Christianity
. The writing style, vocabulary, and theological themes are very similar in both books, reinforcing the idea of a single author
. While some modern scholars question whether the author was indeed the Luke mentioned in the Pauline letters, the traditional attribution remains the most widely accepted view, dating the composition of Acts to around 80–90 AD
. In summary, the Book of Acts was written by Luke, the same author who wrote the Gospel of Luke, based on early church tradition and textual evidence
