The Acts of the Apostles: Who Wrote It, When, and Why?

Now that I have discussed the major themes and emphases of the Acts of the Apostles, I can summarize what (I think) we can know about its author, when he wrote, and why. As I’ve indicated, Acts is the second volume of a two-volume work by the anonynmous author of the Gospel of Luke.  In my discussion of the Gospel I’ve show why the traditional view that the author was Luke the gentile physician, a traveling companion of Paul, is probably not right.  In case you want to read/reread the post, it is here:  https://ehrmanblog.org/the-gospel-of-luke-who-wrote-it-when-and-why/ There I point out what I’ve repeatedly argued on the blog, that in virtually every instance in which the book of Acts can be compared with Paul’s letters in terms of biographical detail, differences emerge.  Some of these differences are minor – the kinds of things a friend might just get wrong; others are major and show that the author misunderstands or at least mischaracterizes Paul on significant issues, in ways hard to explain if he was closely associated with [...]

The Book of Acts in a Nutshell

Acts in a Nutshell The book of Acts is a truly important book for anyone interested in knowing how Christianity began:  it is our only narrative of the spread of the faith in its first thirty years. Acts is a relatively long book – about the size of its companion volume the Gospel of Luke – and there is a lot going on in it.  Have you ever read it all the way through?  Do you know much about it?  If not, this is the post for you.  If so, then try to summarize the major themes and emphases of Acts in one sentence, of fifty words or less. Here’s how I would do it (today!): A companion volume to the Gospel of Luke, Acts narrates the miraculous spread of Christianity from Jerusalem to Rome, from Jew to gentile, through the miraculous deeds and inspired preaching of Jesus’ original apostles and the convert Paul, all empowered by the Spirit and in complete harmony with one another. In this post I’ll unpack this statement and in [...]

More Interesting Questions from Blog Readers

The intriguing questions keep coming.  Here are some more that I've received.  And BTW, if you're not a Gold Member on the blog you might consider moving up to that level: one of the perks is that I do a live Q&A every month with Gold Members, which is recorded and then distributed to them.  It's a terrifically fun event and I get very good questions to address. But for now, here's some that I've addressed in writing: QUESTION This question is about the understanding of atonement across the gospels. Specifically why do Matthew and John think Jesus specifically HAD to die, in your view? Especially Matthew since he is the one I struggle with most. Luke famously doesn’t have atonement and thinks he had to die to bring people to repentance. I think Mark is a Pauline Gospel so it has his theology of Jesus death being a ransom for gentiles in mind. Matthew and John are the ones that I struggle with most, though. I think John says that it is meant to [...]

The Gospel of Matthew. Are You Interested in a More Extended Discussion?

It has just occurred to me (duh) that some blog readers who are enjoying these "In a Nutshell" posts on the books of the New Testament may like to see a more extended exposition of the various issues I address, and I've devoted entire lectures courses for some of these books (and will be doing more).  You might be interested in them. One of the first I did was on the Gospel of Matthew, an eight-lecture course (50 minutes or so each; with two Q&A's; and additional materials provided).  You can find it here.  https://courses.bartehrman.com/matthew   Blog members get a discount with the code Blog5. Whether you want to get the course or not, I thought it would be valuable to explain what I cover there, lecture by lecture.  And so here is a summary! ****************************** The Genius of Matthew Lecture Descriptions   Lecture One:  How Do You Study a Gospel?  Take Matthew For Example.

The God Hypothesis. What Do You Think?

I don’t think you can disprove the existence of God.  And I don’t think you can prove it.  There are some things that by their very nature are not susceptible of proof, at least at this stage of our knowledge, including some things that theoretically exist or not.  If you want to insist that one of the universes within the multiverse is an exact replica of ours down to the very molecule – so that my cosmic double is typing these very words the moment I am – I have no way of proving it or disproving it. (some will argue it's likely, esp. if there is an infinite number of universes – in which case in another one of them my cosmic virtual double is typing these words but changing one of them; and in another….) Even so, that kind of thing could in theory be proven or disproven if human knowledge expands geometrically in the future, since we would (probably) be talking about a physical entity that exists.  But when it comes to [...]

All Four Gospels in One Nutshell

So far in this thread on “The New Testament in a Nutshell” I’ve covered the four Gospels, each in four posts.  The first always begins with a 50-sentence summary of the major themes and emphases of the book.  In this post I want to make things easily accessible for anyone interested in the broad similarities and contrasts of the Gospels, by putting all four sentences in one place. But before that, it would be useful to have a fifty-word summary of all four Gospels as a whole. Give it a try yourself.  What can you come up with?  A statement that is accurate, informative, and concise?  Accuracy is particularly difficult, since a lot of general statements wold not apply to all four Gospels: for example, if your summary was to include a brief comment on the miracles and you included Jesus’ exorcisms, that wouldn’t be right, since Jesus never casts out a demon in the Gospel of John.  And you can’t say that in all four Jesus died (as an atonement) for the sake of [...]

John Versus the Synoptics: How Does Jesus Raise the Dead?

I've discussed how John differs strikingly from the Synoptics, especially considering the stories and sayings/discourses in each.  I've also indicated that they differ strikingly even when they tell the same *kind* of story, but I haven't been able to illustrate that yet.  Here is one of my favorite examples. How does Jesus raise from the dead? In Mark 5 Jesus raises an unnamed young girl, the daughter of Jairus, from the dead; in John 11 he raises a (young?) man from the dead, Lazarus, sister of Mary and Martha.  How do these stories compare and contrast? The following discussion is based on what I say in my textbook (The New Testament: A Historical Introduction to the Early Christian Writings, 7th ed. Oxford University Press), expanded and edited a bit here. ****************************** The differences between John and the Synoptics are particularly striking in stories that they have in common. You can see the differences yourself simply by taking any story of the Synoptics that is also told in John, and comparing the two accounts carefully.   Try [...]

The Gospel of John: For Your Further Reading

I have devoted two posts to major features of the Gospel of John, one that lays out its major themes and emphases, the other that deals with who wrote it, when, and why. Now I can provide some suggestions for further reading, important works written by scholars for non-scholars.   The list is annotated to give you a sense of what each book is about and so help you decide which, if any, might be worth your while. I have divided the list into three sections: Books that provide important discussion of John in general or with respect to a particularly key topic Commentaries that give lengthy introductions to all matters of importance about the Gospel and then go passage by passage to provide more detailed interpretation, where you can dig more deeply into what does a particular word actually means; that the real point of a passage is; how the passage relates to what John says elsewhere or to other parts of the New Testament; where you can we find similar ideas expressed in other [...]

The Gospel of John: Who Wrote It, When, and Why?

Now that I’ve summarized the major themes and emphases of the Gospel of John, I can turn to the historical questions of who wrote it, when, and why.  In this case, the biggest mystery is Who? To start with, the Gospel is anonymous – the author chose never to name himself.  The first author to attribute it to John the son of Zebedee is Irenaeus (around 185 CE).  Later readers found hints in the text to confirm this identification.  The matter may seem a bit convoluted at first, but there is a clear logic to it.  It was thought that the author was identifying himself in John 19:35 and John 21:20-24 as an eyewitness to the life of Jesus, one Gospel calls “the disciple whom Jesus loved.”  And so the question was: which disciple would that be? The figure is mentioned several times earlier in the account, where he is clearly one of Jesus’ closest companions: he is the one leaning on Jesus’ breast at his last meal (John 13:23).  That would [...]

The Gospel of John in a Nutshell

What is the Gospel of John all about, in a nutshell?  It’s worth knowing:  John continues to be one of the favorite books of the Bible and is the (only) source of many of the well-known sayings of Jesus: For God so loved the world that he gave his only son, that whoever believes in him should not perish but have everlasting life (John 3:16) I am the good shepherd; the good shepherd lays down his life for his sheep (John 10:11) I am the Way the Truth and the Life: No one comes to the Father except through me (John 14:6) It is also the Gospel that gives us some of the most memorable miracles of Jesus: Turning water into wine (ch. 2) (the favorite miracle of college students everywhere) Raising Lazarus from the dead (ch. 11)   Have you read John’s Gospel all the way through, or even studied it?  If so, try to summarize it in one sentence of fifty words.  If you don’t know the Gospel well (or at all): keep [...]

Some Intriguing Questions from Readers 2/2025

Here are some interesting readers’ questions I’ve received that I think would be of some interest to other blog members, along with my answers which may or may not be of interest!   QUESTION I often find that historians of early Christianity use the terms “historical Jesus/Paul/whoever” and “real Jesus/Paul/whoever” somewhat interchangeably, which I don’t love. I think there’s a difference between the historical Abraham Lincoln, who is an artificial human construct arrived at by following the rules of historical scholarship, and the real Abraham Lincoln, who is someone we have no access to. Perhaps I’m being too post-modernist though. Perhaps somewhat analogous are Proto-Indo-European, an artificial human reconstructed language obtained by following the rules of historical linguistics to the best of our ability, and whatever was truly spoken by any particular speaker in the Pontic-Caspian steppe in, say, 6000 BCE. Or, as a looser analogy, Biblical religion as it existed in its ideal form in the mind of the priestly redactors of the Tanakh, and Israelite-Judean religion that any particular person in say 600 [...]

Other Sources for Matthew and Luke: M and L! And Who CARES?

We have seen that most scholars agree that the problem of the close similarities and striking differences among our Synoptic Gospels -- the "Synoptic Problem" -- is best solved by thinking that Mark was copied (to a greater or lesser extent) by both Matthew and Luke, the view called "Markan Priority."  The majority continues to believe there was a "sayings source" available independently as well to Matthew and Luke, that gave them many of the sayings of Jesus that they record but are not found in Mark (the Lord's Prayer, the Beatitudes, some of the parables, lots of his memorable one-liners).  Others, as I've said, maintain that Matthew copied Mark and that Luke copied both Matthew and Mark. Even if we agree there was probably a Q source  and even if we don’t, we are still left with the fact that a good number of Matthew's stories are not found in either Mark or Luke (Herod's slaughter of the innocents, the visit of the Magi, a bunch of his parables), just as there are a [...]

Evidence for Q: The Sequence of the Sayings

In my previous post I gave a simplified illustration to show why it is problematic to get rid of the Q source (the hypothetical  collection of sayings found in both Matthew and Luke but not in Mark).  Having this hypothetical source does not actually complicate the solution of the Synoptic Problem, it makes the solution simpler.  Supposing there was a Q is not a perfect solution, but it is better than the alternatives, in my opinion.  As my Doktorvater Bruce Metzger used to say (about Q and other things), "It is the least problematic solution." The reason it makes simplest and best sense is because of the sequence of the sayings of these "double traditions" (the technical term for the sayings materials in the TWO Gospels of Matthew and Luke but not in Mark).  Unlike many of the narratives of these texts, these double-tradition sayings invariably occur in different places in the two Gospels.  Why is that? It would make sense if both of them have a source with a collection of Jesus' sayings of [...]

An Argument for Q: The Hypothetical Source That Seems to Have Existed

Why should we think there was a Q, the hypothetical document that contained principally sayings of Jesus, that was (according to this hypothesis) used by Matthew and Luke (but not by Mark) in constructing their Gospels? It is an issue because if Matthew and Luke both used Mark, as almost everyone agrees (for reasons I laid out in my earlier post), then one has to explain why they have so many other materials (mainly sayings) in common that are *not* found in Mark.  They didn’t get them from Mark!  Where then? In my earlier post I claimed that Matthew does not seem to have gotten those sayings from Luke or Luke from Matthew, and so they both most have gotten them from some other one-time-existing source.  That is a source commonly called Q (for the German word Quelle: Source). But some readers have asked exactly why it is unlikely that Matthew got these sayings from Luke or Luke from Matthew?  In particular, isn’t the best theory the one that has the least hypotheticals?  Why invent [...]

The Q Source Used by Matthew and Luke

If Mark was the first Gospel written, as  I tried to explain in my previous post, and it was used by both Matthew and Luke, how do we explain that there are many places in Matthew and Luke that agree with each but are not in Mark.? They didn’t get these passages from Mark, but if they agree word for word in places, there must be copying.  What are they copying?  Welcome to the world of Q! Q is the hypothetical source that scholars believe was used by Matthew and Luke to supplement the materials they got from Mark (“hypothetical” because it no longer survives – which is true, of course, of the vast majority of the earliest Christian writings).  The Q hypothesis was developed in the 19th century and has been the dominant view of scholarship for the past century, but it has come under attack in recent years (as I mention below).  But it continues to be the most widely accepted hypothesis to help solve the Synoptic Problem, for reasons I’ll explain in [...]

Was Mark Really Written First? The Arguments for “Markan Priority”

I've begun blogging on the "Synoptic Problem," the problem of why Matthew, Mark, and Luke are so similar in so many ways (many of the exact same stories, often told in the same sequence, and even in the very same words), and yet so different (often in wording, sometimes in sequence, etc.).  The solution virtually everyone accepts is that there is some kind of copying going on. The first step is to see if one of them was copied in part by the others, and based on long examinations of all the evidence, the vast majority of scholars have come to agree Matthew and Luke had a copy of Mark that they copied as the basis for their accounts.  They each changed it in places, moving a story to another place, rewording sentences either a little, or a lot, etc..  But Mark was first and the others copied most of it. I should point out that Matthew and Luke almost certainly didn't have the same *copy* of Mark.  And the copies they each had may [...]

Gospel Problems: Does Matthew Ever “Correct” Mark?

In my previous post I indicated that one of the reasons for thinking that Matthew copied Mark instead of the other way around is that there are passages in Mark that can be read in ways (or maybe even were meant in ways) that could be seen as problematic -- they might be worded in an awkward way, for example, or they might say something that cold be seen as confusing or just wrong -- but that in Matthew are worded differently so that there is no longer a problem. That would make sense if Matthew was copying Mark and just reworded something to "correct" it or at least to get rid of the problem.  It would be harder to explain why Mark would create a problem that wasn't in the story he was copying.  If that's right, it would suggest Mark is the source of Matthew. Here's one example to consider out of many.  I choose this one because, well, it's one of my favorites! It comes in the opening of the story [...]

Why Assume the Synoptic Gospels Were COPYING One Another (and Other Sources)?

Why couldn't Matthew, Mark, and Luke just have the same stories?  Why do we have to assume someone was copying someone else's? In yesterday’s post,  I simply stated that copying must have been going on to explain the literary relationship among Matthew, Mark, and Luke, the Synoptic Gospels, since they have so many similarities: they tell many of the same stories, often in the same sequence, and sometimes – lots of times – in the very same words.  That is to say, someone must be copying someone else, or they are all using the same written sources. But some of my students have trouble seeing that if two documents are word-for-word the same, one must be copying the other (or they both are copying a third source).  Many older adults don’t seem to have any problem seeing that, right off the bat.  But younger adults need to be convinced.  And so I do a little experiment with them that more or less proves it.  I do this every year in my New Testament class, which [...]

The Synoptic Problem: Matthew, Mark, and Luke. Who’s Zoomin Who?

Why are Matthew, Mark, and Luke are so similar to each other and yet have so many differences, lots of them minor but some of them significant? In my previous posts I’ve given “Nutshell” explanations of each of these Gospels.  Before moving on to John – which is remarkably different in many ways from these three, both individually and as  group – I want to devote a series of posts to their relationship to one another. How could they be so alike – often word for word the same – without some copying going on?  And how do we account for the (sometimes serious) differences? This has long been known as the “Synoptic Problem.”  It is not a problem connected with John because the features that create the problem for Mathew, Mark, and Luke (their extensive similarities often in extensive verbatim agreements) do not apply to John. I have just reread my explanation of the problem in my textbook The New Testament: A Historical Introduction to the Early Christian Writings 7th ed. (Oxford University Press) [...]
