Dennis E. Smith, one of the editors of the Acts Seminar Report, published as Acts and Christian Beginnings, includes in that publication a short essay on on the identity of the author of Acts (pp. 9-10).
Smith begins by noting that the first writer we know who identified the author of Acts as Luke, a companion of Paul, was Irenaeus who wrote in the late second century. We can read Irenaeus making this assertion in Against Heresies, 3.14.1:
But that this Luke was inseparable from Paul, and his fellow-labourer in the Gospel, he himself clearly evinces, not as a matter of boasting, but as bound to do so by the truth itself. For he says that when Barnabas, and John who was called Mark, had parted company from Paul, and sailed to Cyprus, “we came to Troas;”(10) and when Paul had beheld in a dream a man of Macedonia, saying, “Come into Macedonia, Paul, and help us,” “immediately,” he says, “we endeavoured to go into Macedonia, understanding that the Lord had called us to preach the Gospel unto them.
So Irenaeus was the first to rely upon the prima facie inference of the “we passages” in Acts and conservative scholarship through to the twenty-first century, despite twentieth century research into the the matter, has not uniformly advanced in learning since.
Dennis E. Smith points out that Irenaeus was
who was named Luke and who was a close companion of Paul. Irenaeus was also of the belief that the real Paul wrote all three of those letters and was also the author of the Gospel of Luke. Modern scholarship has largely followed the reasoning and conclusion of Irenaeus insofar as the same author who wrote Acts was also responsible for the Gospel of Luke, but (contrary to what one may expect from web and blog-active New Testament scholars)
few have accepted the theory that a companion of Paul was the author.
So critical readers here can be assured that, according to the word of Smith and Tyson and contrary to some prominent web/blogging scholars, “the majority of critical scholars” do not accept that the author of Acts was a companion of Paul. read more
