Authorship of Luke–Acts
The Gospel of Luke and the Acts of the Apostles make up a two-volume work which scholars call Luke–Acts. The author is not named in either volume. According to a Church tradition, first attested by Irenaeus (c. 130 – c. 202 AD), he was the Luke named as a companion of Paul in three of the Pauline letters, but many modern scholars have expressed doubt that the author of Luke-Acts was the physician Luke, and critical opinion on the subject was assessed to be roughly evenly divided near the end of the 20th century. The eclipse of the traditional attribution to Luke the companion of Paul has meant that an early date for the gospel is now rarely put forward. Most scholars date the composition of the combined work to around 80–90 AD, although some others suggest 90–110, and there is textual evidence (the conflicts between Western and Alexandrian manuscript families) that Luke–Acts was still being substantially revised well into the 2nd century.
