Who wrote act out of the bible?

The books "The Acts of the Apostles" and "The Gospel According to St. Luke" were both said to have been written by a physician named Luke. Luke was likely a disciple of the Apostle Paul. It is probable that the books of Luke and Acts were actually two parts of the same document, addressed to one Theophilus.

While most scholars agree that Luke and Acts appear to be written by the same author, there are always discussions as to who those authors truly were. The books of the New Testament were not actually authored until later in the first century, beginning around 60 to 70 AD. Hence many of the authors were not themselves acquainted with the Savior during his life, but were close associates with those who had known Him, such as the apostles Peter and Paul (Paul having been converted by the Savior after His resurrection). Paul himself was known to have used scribes for several of his own epistles, each employing a slightly different writing style.

It is important to note, however, that none of these discussions should in any way diminish the power of the testimonies being borne by these authors.
