When was the New Testament’s Book of Acts written and why does it matter?


This topic cropped up recently when The Guy visited the adult Bible class at a prominent Presbyterian Church (USA) congregation. Participants are taught that the Book of Acts, which depicts the three decades directly following Jesus Christ’s earthly life, was written between 110 and 120 A.D., a generation later than scholars’ consensus.

Does that seem a trivial technicality?

“A good deal rides on decisions about the date of Acts,” says Joseph Tyson of Southern Methodist University.

Christian tradition holds that Acts reliably records what Jesus’ original followers believed and how the earliest churches spread that message. But if it was written long after the events, that opens up radical theories. Bible experts left and right agree that Acts and the Gospel of Luke are in fact two volumes of a unified work by the same writer, although separated by John’s Gospel in Bibles. (Both books are anonymous but Paul’s colleague Luke is identified as the author in 2nd Century texts so The Guy follows that custom.)

Luke’s Gospel begins: “Since many have undertaken to set down an orderly account of the events that have been fulfilled among us,  just as they were handed on to us by those who from the beginning were eyewitnesses and servants of the word,  I too decided, after investigating everything carefully from the very first,  to write an orderly account for you, most excellent Theophilus,  so that you may know the truth. ...(New Revised Standard Version)

Acts then begins with a specific link back to Luke: “In the first book, Theophilus, I wrote about all that Jesus did and taught from the beginning. ...”  Because of those opening words, the credibility of the New Testament as history is at stake here.  (If interested in who that Theophilus was, see “Religion Q & A” for December 22, 2015, in the archive.)

The Acts discussion is a very revealing example of how various types of Bible scholarship go about their business.
