Help!!
Is anyone on the blog a professional mathematician or statistician? (I’m not looking for someone who’s good with numbers but with someone who makes a living out of it.) If so, and you’d be willing to help me out with a question that probably any sophomore in high school could handle, could you send me a private email at [email protected] ?

Trolling Advice!
Dear Readers and Fans of the Blog: I have gotten a number of comments/complaints about trolling and thought I should just tell you my policy in case you think I should change it. I have two competing principles that I try to keep in balance on the blog. On one hand, I want readers to say what they really, genuinely think and to have a chance, then, to air their views. On the other hand, I don’t want simply to post snide comments by people trolling. And so the rather informal policy I’ve adopted is to post negative comments (so that I’m not censoring) two, three, or four times as they come to me; after I’ve had enough, I warn the person; after that I simply don’t post their comments. Does that sound reasonable? Or do you think I should (a) simply not post negative comments; (b) post absolutely every negative comment I get; or (c) something else? The reason I’m concerned is that you, the readers, drive the blog, and are its raison d’être. […]

Christians and their Exaggerated Numbers
I have started discussing the fascinating article by Keith Hopkins, “Christian Number and Its Implications” (see my post of two days ago). After discussing some of the problems with knowing how to “count” Christians (i.e., who counts as a Christian), he reflects for a bit on the problems presented to us by our sources of information. The basic problem is that our sources don’t *give* us much information! No one from the early Christian church was a statistician and no one kept records of how many people were being converted. And the comments we find that are of any relevance turn out to be so broad, generalized, and suspicious as to be of no use to us at all. Sometimes, a source will give numbers, but they clearly cannot be trusted. Take the book of Acts. This is our first account of early Christianity, and, of course, became the “canonical” account. According to Acts 2 (this and the following are examples that *I’m* giving; they are not found in Hopkins), just 50 days after Jesus’ […]

Paul in a Nutshell and NT Views of Crucifixion: Readers Mailbag May 13, 2016
In this week’s Readers Mailbag I will deal with two rather massively significant questions, one on the life and message of Paul and the other on the different understandings of Jesus crucifixion in the New Testament. If you have any question(s) you would like me to address in the future, let me know! ******************************************************************* QUESTION: I am wondering what you would consider the most important things to know about the Apostle Paul. Sometimes when I am forced to give a succinct answer to a question, it can have a lot of value. So while I will be going into some depth in the Sunday School class, including referencing some of your work, I would love to hear your expertise on Paul distilled into a brief summary (if at all possible). RESPONSE: Right! Obviously some scholars have written very long books on Paul’s life, message, and mission. So, let me give here the very basic essentials, as I see them, in bullet point form. Paul started life as a highly religious Jew, zealous to […]

The Rate of Christian Growth
I have been discussing the fascinating article by Keith Hopkins, “Christian Number and Its Implications,” about how many people converted to Christianity at certain points of time (say, from ten years after Jesus’ death to the time the emperor Constantine converted in the year 312). As we have seen so far, the first problem Hopkins deals with is how to count – that is, who counts as a Christian? Hopkins takes the (in my opinion) justifiable and sensible view that if someone considered themselves to be a follower of Jesus (whether they were proto-orthodox, or Sethian, or Marcionite, or Ebionite, or anything else) they should be counted. The second problem, as we have also seen, is that our sources don’t give us any reliable statistics, or indeed statistics of any kind. Instead, our sources (and, by the way, without sources we have no evidence, only guess work, even if it is educated guess work) are highly prone to exaggeration. And so the book of Acts indicates that within a couple of months, some 8000 Jews […]

How Many Christians Were There?
There are a lot of things that I’m really very interested in that I’m not very good at. As a kid I was passionate about baseball. I was an All Star every year up to high school, but I really wasn’t all that great. I was just better than most of the other kids, who *really* weren’t great. It was a rather low bar. Same with tennis. Same with a lot of things – even into adulthood. As an adult I’ve long had an attraction to numbers, but I’m not very good at them. I’m fascinated by them, but I can’t work out much of any kind of sophisticated mathematical formula to save my soul. That’s why last week I asked for some help on the blog. I needed someone to come up with a formula for me to crunch some numbers. And several people obliged. Many, many thanks to all who helped. I’m very much in their debt. It’s amazing to me the kinds of expertise that are out there. Some of my respondents […]

Playing with the Numbers (of Christians)
I have been musing on the rate of growth of the Christian church during the first three hundred years, and have pointed out some problems with Rodney Stark’s discussion. I won’t go over all that again here. I will say that his argument tends to be very convenient for his … argument. What he points out is that a growth rate over time of about 40% grows the church from about 1000 Christians in the year 40 (that’s a number I find problematic) gets you to about 6 million Christians in the year 300, and that is almost exactly the rate of growth of the Mormon church since it was started in the 19th century. Stark is an expert on the Mormon church, from a sociological perspective; and so it is not surprising that he is particularly drawn to this statistic. But if you crunch the numbers a bit more realistically, there still is sensible set of figures that emerge. If, as the NT actually indicates, Christianity started out with about 20 of Jesus’ followers […]

Whom Do We Consider a Christian?
Who counts as a Christian? When I was a hard-core evangelical at Moody Bible Institute, we had a pretty clear and straightforward answer: if you have not been born again and accepted Christ as your personal Lord and Savior, you were not a Christian. No matter what you believed or where you worshiped or how you lived. This meant, among other things, that most people who called themselves Christian were not really Christian. Episcopalians, Methodists, Lutherans, Presbyterians – most of them were not really Christians. Roman Catholics were certainly not Christians. Greek Orthodox? Not even close. Mormons? You gotta be kidding. At the time I knew people who had an even more rigorous definition: if you did not know the exact day and hour in which you had accepted Christ as your Lord and Savior, then you hadn’t done so, and were not saved. Some were even more strict: you not only had to have accepted Christ, you had to have been baptized by immersion – dunked in the water, as an adult. Anyone who had not […]

How Significant Was Early Christianity?
I return now to Roman historian Keith Hopkins’s fascinating and influential article “Christian Number and It’s Implications.” As I pointed out, for the sake of his article, and after checking it out for plausibility, Hopkins accepts the calculations of Rodney Stark that if Christianity started with 1000 believers in the year 40 CE, and ended up being 10% of the empire (60 million believers) by the time of the Emperor Constantine, you would need a growth rate of about 40% per decade, or, as Hopkins prefers putting it 3.4%). Obviously, as I’ve stated, but need to stress again, we cannot be and are not really thinking that there was a steady rate of growth, that every year there was the same percentage of increase. We’re talking big numbers over a long range of time, so the *average* rate of growth is just that, an average. Some years there may have been a loss of numbers, other years a huge spike. So take that as given. But if we *were* talking about a steady rate, there […]

How Many Churches? How Many Letters?
In his important and stimulating article, “Christian Number and Its Implications,” Roman historian Keith Hopkins next begins to think about the implications about the size of the Christian church at different periods. One point to emphasize is that there was not simply one church. There were lots of churches in lots of places, and it is a myth to think that they were all one big cohesive bunch. On the contrary, they were often (as we see in our records) often at odds with each other. But even more than that, even within one city – if it was large enough (think Rome or Antioch for example) there would have been more than one church. And why? Because there would have been too many people to meet in one place. The first time we have any evidence of a church “building” – that is, what we today normally think of as a church (the Baptist church on the corner; the Methodist church up the street) – is not until the middle of the third Christian […]

The Accuracy of Paul’s Letter to the Galatians
I’m a couple of days behind on my Weekly Readers’ Mailbag. I’ve been so caught up in talking about the conversion of the Roman empire to Christianity that I forgot all about it! So here is last week’s a day late. IN it I deal with one question which turns out to be three questions, all of them related to the the historical accuracy of Paul’s letter to the Galatians.. QUESTION: Bart, quick question that’s bothering me. You often say that we can’t be sure of the gospels’ accuracy (due to intentional and unintentional changes over time and location). The idea is that we can’t know what the original really said (even if it names its author (e.g. 1 Tim, 2, Tim, etc.). You often say there are so many changes that we can’t really know what the original was. I always assume you mean in the small details and that you assume the main sense of the texts are fairly accurate to the original. Anyway, I’ve heard you say emphatically that […]

Progressive Spirit Interview
On March 27, 2016, I had an interview with John Shuck for the Progressive Spirit Podcast. Progressive Spirit (formerly Religion For Life) is an exciting and intelligent program about Spirituality and Social Justice. The program is a production of KBOO Community Radio in Portland, Oregon. John interviewed me about his new book Jesus Before the Gospels: How the Earliest Christians Remembered, Changed, and Invented Their Stories of the Savior. In the book as many of you know, I look at research on memory–how it’s formed, how it’s recalled, how it can change when transmitted from person to person, and how it can be remolded based on historical perspective and current events, all in order to helpe us better understand how traditions about Jesus were in circulation in the years before they were written down. Jesus Before the Gospels is available in hardcover, audiobook and for Kindle. Please adjust gear icon for high-definition.

How Many Christians Could Read?
How many Christians by near the end of the New Testament period – say, 100 CE – could read and write? In his intriguing article “Christian Number and Its Implications,” Roman historian Keith Hopkins tries to come up with some ball park figures. As you may recall, he is assuming that there were Christian churches in about 100 communities in the world at the time (we have references to about 50 in our surviving texts, and he is supposing that maybe there were twice as many as we have any evidence for); and he agrees that if Christianity started out with about 1000 believers in the year 40 then with a growth rate of 3.4% per year, by the year 100 there would be just over 7000 Christians in the world. That would mean the 100 churches would have an average of 70 believers. (Some of course would be larger – think, Rome – others would be much smaller; we’re talking averages here. And if Rome did have, say 120 believers, they would be meeting […]

The Resurrection and the Beginning of the Church
In my book on the Christianization of the Empire, I probably will not be talking about *how*, exactly, Christianity started. That’s a very thorny issue and not directly germane to what I want to do in the book. And I’ve talked about it a bit in a couple of my other books, especially How Jesus Became God and Peter, Paul, and Mary Magdalene. In the former book my main interest was precisely what the title indicates. There I argued that the key event that made the followers of Jesus come to think that he was a divine being was their experience of the resurrection. Looked at from another angle, though, that moment can be considered the key not only to later Christian views of Jesus, but also to the question of when Christianity started as a distinct set of beliefs and practices. Before the resurrection-belief, there was nothing about Jesus followers that would differentiate them in any truly significant way from other Jews. After the belief there was. That may, of course, be granting too […]

Jesus’ Death; Good Scholars; and Writing the First Book: Readers’ Mailbag May 28, 2016
I have three rather wide ranging questions to deal with in this week’s Readers’ Mailbag: one on the understanding of Christ’s death as a sacrifice (or not); one on whom I like to read among NT scholars; and one on how to publish a scholarly book. This should be fun! If you have a question you’d like me to address, simply ask it in any comment on any post (whether it’s relevant to the post or not). QUESTION: Would you agree with the statement of scholars like Marcus Borg that Jesus died BECAUSE of the sins of the world and not FOR the sins of the world? Scholars like Borg are quite emphatic that the death of Jesus is not a sacrifice in the way that most (i.e. fundamentalist) Christians understand it: Jesus died for our sins and by believing in Jesus we gain eternal life. Rather, Jesus’ death is understood as a WAY to God: That by following the life of Jesus and offering up our suffering to God we walk in the […]

A Personal Note and a Bit of a Bummer
This post is on a personal note and will be a bit self-indulgent, so if you’re looking for some information about the history or literature of early Christianity, this won’t the right time or place. As many of you know from earlier blog posts, I was supposed to go off on a research trip to Greece (Athens), Egypt (Alexandria), and Italy (Rome), in connection with my work on my current project, The Triumph of Christianity (or whatever we call it) dealing with the Christianization of the Roman Empire. My idea was to go to these places to see formerly “pagan” sites that were lost, changed, “converted” or destroyed by Christians in the fourth and later centuries (e.g., destroyed temples; shrines converted into churches; and so on). I was supposed to go today. But I have had to cancel the trip. Yesterday while starting to do some preliminary packing I bent over to pick up a bag of books, and my back went out. Bad. Not “Call-911-and-the-Morgue” bad, but bad enough. I had done something similar […]

Paul as a Persecutor of the Church
The questions of what early Christianity originally *was* and of how it got *started* are closely related to one another. Both questions are also closely tied to the life, beliefs, and writings of Paul, for one very good reason: Paul is the first Christian author whose writings survive. Any discussion of Christianity before his time needs to consider at some length what he has to say. I should point out as well that a lot of modern people (including some scholars) claim that it was Paul himself who started Christianity. I think that is going too far, in fact maybe way too far, for reasons that will become apparent in this post and the next. Occasionally Paul will give us some clues about pre-Pauline Christianity. One of the most important passages is in Galatians 1, where he discusses his own “about face,” when he turned from being a persecutor of the faith to being its great apostle. In Gal. 1:13 Paul reminds his readers that they know what he was like before he had come […]

Was Paul the Founder of Christianity? Or Was it Mary, Peter…or Jesus?
Who is the founder of Christianity? It is often claimed that the Founder of Christianity was the apostle Paul – or at least that he was the co-Founder, along with Jesus. The idea behind this claim is that Christianity is not really about the historical Jesus. Yes, his words are hugely important, and yes it is also important to know that he did all those miraculous deeds. But his public ministry is not the core of Christian belief. Instead, the core of Christianity is the belief in his death and resurrection. And this is what Paul preached, not what Jesus preached. So that even if Jesus’ life and teachings are important, they are not really what Christianity is about. Christianity is about believing in his death and resurrection for salvation. And since, in this view, it was Paul who first formulated that belief, he is the founder of the Christianity religion (or co-founder). Paul vs. Jesus: Who is the Christianity Creator? I have never found this line of argument convincing, for two reasons. The first […]

The Core of Paul’s Gospel
A lot of people (at least in my experience) think that Paul is the one who should be considered the “founder” of Christianity – that he is the one who took Jesus’ simple preaching about the coming kingdom of God and altered and expanded it into a complicated doctrine of sin and redemption, being the first of Jesus’ followers to maintain that it was the death and resurrection of Jesus that brought about salvation. In my previous post I tried to show that this can’t be the case, because Paul was persecuting Christians already before he had converted, and these were certainly people who believed in Jesus’ death and resurrection. There is a second reason for thinking that Paul is not the one who invented the idea that Jesus’ death was some kind of atoning sacrifice for sins. That’s because Paul explicitly tells us that he learned it from others. Those of you who are Bible Quiz Whizzes may be thinking about a passage in Galatians where Paul seems to say the opposite, that he […]
