when was the book of Acts Written

Traditional belief is that the Apostle Luke wrote the book of Acts (Acts of the Apostles) around 60 AD. Contemporary thought is that the book was written by an unknown author between 80 and 150 AD. I have found no sources that have determined the age of the author at the time of the writing.

How old was Luke when he wrote the Book of Acts

While giving a very detailed account of Jesus’ life, the Bible writer Luke gives us very few details of himself. The time of his birth, or his age when he wrote the Gospel of Luke, or Acts of Apostles are not recorded. A physician and faithful companion of the apostle Paul. He was the writer of the Gospel of Luke and of the Acts of Apostles. That Luke was well educated is apparent from his writings. Also, his background as a doctor is noticeable in his use of medical terms.—Lu 4:38; Ac 28:8. Luke did not speak of himself as an eyewitness of the events in the life of Christ that are recorded in his Gospel account. (Lu 1:2) So, he apparently became a believer sometime after Pentecost of 33 C.E. Although Luke is nowhere named in the account, ancient authorities are agreed that he was the writer. The Gospel is attributed to Luke in the Muratorian Fragment (c. 170 C.E.) and was accepted by such second-century writers as Irenaeus and Clement of Alexandria. Internal evidence also points strongly to Luke. Paul speaks of him at Colossians 4:14 as “Luke the beloved physician,” and his work is of the scholarly order one would expect from a well-educated man, such as a doctor. His fine choice of language and his extensive vocabulary, larger than that of the other three Gospel writers combined, make possible a most careful and comprehensive treatment of his vital subject. Luke was not, of course, an eyewitness of all the events he records in his Gospel, not being one of the 12 and probably not even a believer until after Jesus’ death. However, he was very closely associated with Paul in the missionary field. Prime source: The scriptures cited and ” Insight on the Scriptures, Volume 1
