Acts? We know what it says. Historians have demonstrated Acts is absolutely 100% historical fiction.
The Mystery of Acts: Unraveling Its Story Richard Purvoe (American biblical scholar, former Episcopal priest, and Fellow of the Westar Institute. Specialist on Acts)
The author of Acts unwittingly committed a near-perfect crime: He told his story so well that all rival accounts vanished with but the faintest of traces. And thus future generations were left with no documents that recount the history of the early Christian tradition; because Acts is not history. According to Richard Pervo, 'Acts is a beautiful house that readers may happily admire, but it is not a home in which the historian can responsibly live.' Luke did not even aspire to write history but rather told his story to defend the gentile communities of his day as the legitimate heirs of Israelite religion. In The Mystery of Acts, Pervo explores the problem of history in Acts by asking, and answering, the fundamental questions: Who wrote Acts? Where was Acts written? When was Acts written? Why was Acts written? How was Acts written? The result is a veritable tour-de-force that enlighten, entertains, and brings Acts to life.
Pervo writes with verve and has a commanding knowledge of the literature on Acts, and his assessment of the theological intent of Acts is informative. --The Bible Today
Richard Pervo, who has dedicated most of his scholarly life to the study of Acts, is an international authority in this area. His new book is intended specifically to introduce the non-specialist to recent research in the field by focusing on the problems of attempting to derive history from the text; indeed, Pervo appreciates the author of Acts more as a creative catechist than as an historian.
-This is the most important book I have read in five years. Bravo Pervo! Summarizing the discoveries made during the writing of his magisterial commentary on Acts, this little book makes it wonderfully clear that there is little if anything of historical value in the book of Acts, apart from what it can tell us about the community that wrote it. In one fell swoop, the only basis of support for the traditional model of Christian origins has been eliminated. It is now possible to entertain seriously other models of Christian origins, including the theory that Christianity did not begin at any particular place in space or moment in time, but rather began like the ancient religions of Egypt, India, Greece, and Rome. The fact that as soon as the curtain goes up on the stage of Christian history there is evidence of division and "heresies" such as Docetism--inexplicable on the basis of traditional notions of an historical "Jesus of Nazareth"--now becomes understandable if "Christianity" developed (and continues to develop) as the intertwining of threads of religious tradition into braids of tradition that change as time goes on. The origins of some threads disappear into the mists of prehistory, others enter the braid at known points in time and space. Some threads leave the braid, the braid fragments into various "Christianities," and the color of the various threads may change as a function of time and place.
As we can see, in order for Acts to be any kind of history, one would have to assume that all of these parallels are merely historical coincidences which is orders of magnitude less probable than that they are simply inventions that were intentionally created to reflect one another. It’s certainly possible for a couple of these coincidences to be historical, but it is nigh impossible for all of them to be historical. Either way, there isn’t any way to weed out any of the possible historical details from within this plethora of fictional constructions. Overall, Acts just shares far too many features with popular adventure novels that were written during the same period, in order to lend it any trust as history. Here’s an overview of those features:
1) They all promote a particular god or religion.
2) They are all travel narratives.
3) They all involve miraculous or amazing events.
4) They all include encounters with fabulous or exotic people.
5) They often incorporate a theme of chaste couples that are separated and then reunited.
6) They all feature exciting narratives of captivities and escapes.
7) They often include themes of persecution.
8) They often include episodes involving excited crowds.
9) They often involve divine rescues from danger.
10) They often have divine revelations which are integral to the plot
Since Acts shares all of these features and thus looks exactly like an ancient novel of the period, there is simply no good reason to assume that all of the parallels it has with other literary sources are merely historical coincidences. Rather, we should conclude that they are in fact what they have been shown to be: literary constructs and other elements of fiction.
