I have an interesting lecture for you to listen to today, by Dr. Tim McGrew. He is a professor of philosophy at Western Michigan University.

The MP3 file is here.

I do not have a summary of the lecture, but I do have an article that explains what undesigned coincidences are.

Lydia McGrew explains the concept of undesigned coincidences on her blog:

Undesigned coincidences in the Gospels … is an argument that was well-known in the nineteenth century but has, for no really clear reason, simply been forgotten as time has gone on. It is a cumulative case argument that the Gospels reflect, to an important extent, independent knowledge of actual events. Please note that this argument is quite independent of one’s preferred answer to the synoptic question. That is to say, even if, e.g., Mark was the first Gospel and others had access to Mark and show signs of literary dependence on Mark, the argument from undesigned coincidences provides evidence for independent knowledge of real events among the Gospel writers. There are many more of such coincidences beyond those given in the talk.

Basically, this argument finds cases where the same story is in two sources, but where some important detail is left out of one account so that something about the story seems out of place. But the other source has the missing detail that unlocks the mystery. This supports the view that the sources are independent witnesses of the same events. Multiple attestation is an indicator that the material is historical.

My favorite example of undesigned coincidences is the Philip example from John 6.

Lydia explains that example here:

As I was listening to Tim’s examples, I was struck by all the reasons there might be for a real eyewitness not to fill out the explanation for a detail. Think for example how tedious it is to listen to someone who goes back to explain every little detail he mentions in a story.

[…]Similarly, as John is telling the story about the feeding of the five thousand, it would be quite natural for him to say that Jesus asked Philip where they could buy bread if he were really an eyewitness–that is, because he remembered that Jesus did ask Philip. (Tim talks about why it was Philip in the interview.) But John himself might have had to stop and think for a moment if someone had asked him, “Why did Jesus ask Philip rather than any of the other disciples?” Presumably when John told the story, he wasn’t particularly thinking about some special reason for Jesus to select Philip for the question. But if someone were forging the story as fiction, he would have a reason for choosing to use a given disciple as a character at that point in his fictional narrative, and therefore he would be unlikely to choose that character without making the reason clearer to his readers.

All sorts of such things can happen when one is telling a true story, especially a story one has witnessed. One gets caught up in what one actually remembers and drops in incidental references to small facts, which facts are to some extent selected randomly by the memory as one brings the scene back to memory. This is typical of real memoirs but not of elaborate forgeries.

If you think this is interesting and useful, then give the lecture a listen.

What criteria do historians use to get to the minimal facts about the historical Jesus?

Sherlock Holmes and John Watson: let’s take a look at the facts

Have you ever heard Gary Habermas, Michael Licona or William Lane Craig defend the resurrection of Jesus in a debate by saying that the resurrection is the best explanation for the “minimal facts” about Jesus? The lists of minimal facts that they use are typically agreed to by their opponents during the debates. Minimal facts are the parts of the New Testament that meet a set of strict historical criteria. These are the facts that skeptical historians agree with, totally apart from any religious beliefs.

So what are the criteria that skeptical historians use to derive a list of minimal facts about Jesus?

Dr. Craig explains them in this article.

Excerpt:

The other way, more influential in contemporary New Testament scholarship, is to establish specific facts about Jesus without assuming the general reliability of the Gospels. The key here are the so-called “Criteria of Authenticity” which enable us to establish specific sayings or events in Jesus’ life as historical. Scholars involved in the quest of the historical Jesus have enunciated a number of these critieria for detecting historically authentic features of Jesus, such as dissimilarity to Christian teaching, multiple attestation, linguistic semitisms, traces of Palestinian milieu, retention of embarrassing material, coherence with other authentic material, and so forth.

It is somewhat misleading to call these “criteria,” for they aim at stating sufficient, not necessary, conditions of historicity. This is easy to see: suppose a saying is multiply attested and dissimilar but not embarrassing. If embarrassment were a necessary condition of authenticity, then the saying would have to be deemed inauthentic, which is wrong-headed, since its multiple attestation and dissimilarity are sufficient for authenticity. Of course, the criteria are defeasible, meaning that they are not infallible guides to authenticity. They might be better called “Indications of Authenticity” or “Signs of Credibility.”

In point of fact, what the criteria really amount to are statements about the effect of certain types of evidence upon the probability of various sayings or events in Jesus’ life. For some saying or event S and evidence of a certain type E, the criteria would state that, all things being equal, the probability of S given E is greater than the probability of S on our background knowledge alone. So, for example, all else being equal, the probability of some event or saying is greater given its multiple attestation than it would have been without it.

What are some of the factors that might serve the role of E in increasing the probability of some saying or event S? The following are some of the most important:

(1) Historical congruence: S fits in with known historical facts concerning the context in which S is said to have occurred.

(2) Independent, early attestation: S appears in multiple sources which are near to the time at which S is alleged to have occurred and which depend neither upon each other nor a common source.

(3) Embarrassment: S is awkward or counter-productive for the persons who serve as the source of information for S.

(4) Dissimilarity: S is unlike antecedent Jewish thought-forms and/or unlike subsequent Christian thought-forms.

(5) Semitisms: traces in the narrative of Aramaic or Hebrew linguistic forms.

(6) Coherence: S is consistent with already established facts about Jesus.

For a good discussion of these factors see Robert Stein, “The ‘Criteria’ for Authenticity,” in Gospel Perspectives I, ed. R. T. France and David Wenham (Sheffield, England: JSOT Press, 1980), pp. 225-63.

Notice that these “criteria” do not presuppose the general reliability of the Gospels. Rather they focus on a particular saying or event and give evidence for thinking that specific element of Jesus’ life to be historical, regardless of the general reliability of the document in which the particular saying or event is reported. These same “criteria” are thus applicable to reports of Jesus found in the apocryphal Gospels, or rabbinical writings, or even the Qur’an. Of course, if the Gospels can be shown to be generally reliable documents, so much the better! But the “criteria” do not depend on any such presupposition. They serve to help spot historical kernels even in the midst of historical chaff. Thus we need not concern ourselves with defending the Gospels’ every claim attributed to Jesus in the gospels; the question will be whether we can establish enough about Jesus to make faith in him reasonable.

And you can see Dr. Craig using these criteria to defend minimal facts in his debates. For example, in his debate with Ehrman, he alludes to the criteria when making his case for the empty tomb.

Here, he uses multiple attestation and the criteria of embarrassment:

Among the reasons which have led most scholars to this conclusion are the following:

1. The empty tomb is also multiply attested by independent, early sources.

Mark’s source didn’t end with the burial, but with the story of the empty tomb, which is tied to the burial story verbally and grammatically. Moreover, Matthew and John have independent sources about the empty tomb; it’s also mentioned in the sermons in the Acts of the Apostles (2.29; 13.36); and it’s implied by Paul in his first letter to the Corinthian church (I Cor. 15.4). Thus, we have again multiple, early, independent attestation of the fact of the empty tomb.

2. The tomb was discovered empty by women.

In patriarchal Jewish society the testimony of women was not highly regarded. In fact, the Jewish historian Josephus says that women weren’t even permitted to serve as witnesses in a Jewish court of law. Now in light of this fact, how remarkable it is that it is women who are the discoverers of Jesus’ empty tomb. Any later legendary account would certainly have made male disciples like Peter and John discover the empty tomb. The fact that it is women, rather than men, who are the discoverers of the empty tomb is best explained by the fact that they were the chief witnesses to the fact of the empty tomb, and the Gospel writers faithfully record what, for them, was an awkward and embarrassing fact.

There are actually a few more reasons for believing in the empty tomb that he doesn’t go into in the debate, but you can find them in his written work. For example, in his essay on Gerd Ludemann’s “vision” hypothesis. That essay covers the reasons for all four of his minimal facts.

So, if you are going to talk about the resurrection with a skeptic, you don’t want to invoke the Bible as some sort of inerrant/inspired Holy Book.

Try this approach instead:

  1. Explain the criteria that historians use to get their lists of minimal facts
  2. Explain your list of minimal facts
  3. Defend your list of minimal facts using the criteria
  4. Cite skeptics who admit to each of your minimal facts, to show that they are widely accepted
  5. List some parts of the Bible that don’t pass the criteria (e.g. – guard at the tomb, Matthew earthquake)
  6. Explain why those parts don’t pass the criteria, and explain that they are not part of your case
  7. Challenge your opponent to either deny some or all the facts, or propose a naturalistic alternative that explains the facts better than the resurrection
  8. Don’t let your opponent attack any of your minimal facts by attacking other parts of the Bible (e.g. – the number of angels being one or two, etc.)

And remember that there is no good case for the resurrection that does not make heavy use of the early creed in 1 Corinthians 15:3-8. You have to use that – it’s the law.

Back to the minimal facts criteria. The best essay on the minimal facts criteria that I’ve read is the one by Robert H. Stein in “Contending with Christianity’s Critics“. It’s a good short essay that goes over all the historical criteria that are used to derive the short list of facts from which we infer the conclusion “God raised Jesus from the dead”. That whole book is really very, very good.

What’s the earliest historical report of the resurrection of Jesus?

Sherlock Holmes and John Watson: let's take a look at the facts
Sherlock Holmes and John Watson: let’s take a look at the facts

First, the creed – which is found in 1 Corinthians 15:3-8:

3For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,

4that he was buried, that he was raised on the third day according to the Scriptures,

5and that he appeared to Peter, and then to the Twelve.

6After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.

7Then he appeared to James, then to all the apostles,

8and last of all he appeared to me also, as to one abnormally born.

Almost all historians accept this creed as dating back to within 5 years of the death of Jesus. But why?

Here’s an article about this early creed from ancient historian Gary Habermas.

Quote:

(1) Contemporary critical scholars agree that the apostle Paul is the primary witness to the early resurrection experiences. A former opponent (1 Cor. 15:9; Gal. 1:13-14; Phil. 3:4-7), Paul states that the risen Jesus appeared personally to him (1 Cor. 9:1; 15:8; Gal. 1:16). The scholarly consensus here is attested by atheist Michael Martin, who avers: “However, we have only one contemporary eyewitness account of a postresurrection appearance of Jesus, namely Paul’s.”[3]

(2) In addition to Paul’s own experience, few conclusions are more widely recognized than that, in 1 Corinthians 15:3ff., Paul records an ancient oral tradition(s). This pre-Pauline report summarizes the early Gospel content, that Christ died for human sin, was buried, rose from the dead, and then appeared to many witnesses, both individuals and groups.

Paul is clear that this material was not his own but that he had passed on to others what he had received earlier, as the center of his message (15:3). There are many textual indications that the material pre-dates Paul. Most directly, the apostle employs paredoka and parelabon, the equivalent Greek terms for delivering and receiving rabbinic tradition (cf. 1 Cor. 11:23). Indirect indications of a traditional text(s) include the sentence structure and verbal parallelism, diction, and the triple sequence of kai hoti Further, several non-Pauline words, the proper names of Cephas (cf. Lk. 24:34) and James, and the possibility of an Aramaic original are all significant. Fuller attests to the unanimity of scholarship here: “It is almost universally agreed today that Paul is here citing tradition.”[4] Critical scholars agree that Paul received the material well before this book was written.[5]

The most popular view is that Paul received this material during his trip to Jerusalem just three years after his conversion, to visit Peter and James, the brother of Jesus (Gal. 1:18-19), both of whose names appear in the appearance list (1 Cor. 15:5; 7). An important hint here is Paul’s use of the verb historesai (1:18), a term that indicates the investigation of a topic.[6] The immediate context both before and after reveals this subject matter: Paul was inquiring concerning the nature of the Gospel proclamation (Gal. 1:11-2:10), of which Jesus’ resurrection was the center (1 Cor. 15:3-4, 14, 17; Gal. 1:11, 16).

Critical scholars generally agree that this pre-Pauline creed(s) may be the earliest in the New Testament. Ulrich Wilckens asserts that it “indubitably goes back to the oldest phase of all in the history of primitive Christianity.”[7] Joachim Jeremias agrees that it is, “the earliest tradition of all.”[8] Perhaps a bit too optimistically, Walter Kasper even thinks that it was possibly even “in use by the end of 30 AD . . . .”[9]

Indicating the wide approval on this subject, even more skeptical scholars frequently agree. Gerd Ludemann maintains that “the elements in the tradition are to be dated to the first two years after the crucifixion of Jesus. . . . not later than three years. . . . the formation of the appearance traditions mentioned in I Cor.15.3-8 falls into the time between 30 and 33 CE. . . .”[10] Similarly, Michael Goulder thinks that it “goes back at least to what Paul was taught when he was converted, a couple of years after the crucifixion.”[11] Thomas Sheehan agrees that this tradition “probably goes back to at least 32-34 C.E., that is, to within two to four years of the crucifixion.”[12] Others clearly consent.[13]

Overall, my recent overview of critical sources mentioned above indicates that those who provide a date generally opt for Paul’s reception of this report relatively soon after Jesus’ death, by the early to mid-30s A.D.[14] This provides an additional source that appears just a half step removed from eyewitness testimony.

(3) Paul was so careful to assure the content of his Gospel message, that he made a second trip to Jerusalem (Gal. 2:1-10) specifically to be absolutely sure that he had not been mistaken (2:2). The first time he met with Peter and James (Gal. 1:18-20). On this occasion, the same two men were there, plus the apostle John (2:9). Paul was clearly doing his research by seeking out the chief apostles. As Martin Hengel notes, “Evidently the tradition of I Cor. 15.3 had been subjected to many tests” by Paul.[15]

These four apostles were the chief authorities in the early church, and each is represented in the list of those who had seen the resurrected Jesus (1 Cor. 15:5-7). So their confirmation of Paul’s Gospel preaching (Gal. 2:9), especially given the apostolic concern to insure doctrinal truth in the early church, is certainly significant. On Paul’s word, we are again just a short distance from a firsthand report.

(4) Not only do we have Paul’s account that the other major apostles confirmed his Gospel message, but he provides the reverse testimony, too. After listing Jesus’ resurrection appearances, Paul tells us he also knew what the other apostles were preaching regarding Jesus’ appearances, and it was the same as his own teaching on this subject (1 Cor. 15:11). As one, they proclaimed that Jesus was raised from the dead (15:12, 15). So Paul narrates both the more indirect confirmation of his Gospel message by the apostolic leaders, plus his firsthand, direct approval of their resurrection message.

Here’s a great article from Eric Chabot, director of Ratio Christi Apologetics Alliance, The Ohio State University to explain who accepts this creed. It’s not just conservatives!

Excerpt:

Even the co-founder Jesus Seminar member John Dominic Crossan, writes:

“Paul wrote to the Corinthians from Ephesus in the early 50s C.E. But he says in 1 Corinthians 15:3 that “I handed on to you as of first importance which I in turn received.” The most likely source and time for his reception of that tradition would have been Jerusalem in the early 30s when, according to Galatians 1:18, he “went up to Jerusalem to visit Cephas [Peter] and stayed with him fifteen days” (11).

This comment by Crossan makes sense because within the creed Paul calls Peter by his Aramic name, Cephas. Hence, if this tradition originated in the Aramaic language, the two locations that people spoke Aramaic were Galilee and Judea. (12) The Greek term “historeo” is translated as “to visit” or “to interview.” (13) Hence, Paul’s purpose of the trip was probably designed to affirm the resurrection story with Peter who had been an actual eyewitness to the resurrected Christ (1 Cor. 15:5).

Now the Jesus Seminar was a radical group of scholars – these were not moderates. Crossan himself admitted to being an atheist in his debate with William Lane Craig. So here you have an atheist admitting that 1 Cor. 15:3-8 is early and in contact with eyewitnesses.

What are the historical arguments for the empty tomb story?

I wanted to go over this article by William Lane Craig which includes a discussion of the empty tomb, along with the other minimal facts that support the resurrection.

The word resurrection means bodily resurrection

The concept of resurrection in use among the first converts to Christianity was a Jewish concept of resurrection. And that concept of resurrection is unequivocally in favor of a bodily resurrection. The body (soma) that went into the grave is the body (soma) that came out.

Craig explains what this means with respect to the fast start of Christian belief:

For a first century Jew the idea that a man might be raised from the dead while his body remained in the tomb was simply a contradiction in terms. In the words of E. E. Ellis, “It is very unlikely that the earliest Palestinian Christians could conceive of any distinction between resurrection and physical, ‘grave emptying’ resurrection. To them an anastasis without an empty grave would have been about as meaningful as a square circle.”

And:

Even if the disciples had believed in the resurrection of Jesus, it is doubtful they would have generated any following. So long as the body was interred in the tomb, a Christian movement founded on belief in the resurrection of the dead man would have been an impossible folly.

It’s significant that the belief in the resurrection started off in the city where the tomb was located. Anyone, such as the Romans or Jewish high priests, who wanted to nip the movement in the bud could easily have produced the body to end it all. They did not do so, because they could not do so, although they had every reason to do so.

There are multiple early, eyewitness sources for the empty tomb

Paul’s early creed from 1 Corinthians 15:3-7, dated to within 5 years of the crucifixion, implies the empty tomb.

Craig writes:

In the formula cited by Paul the expression “he was raised” following the phrase “he was buried” implies the empty tomb. A first century Jew could not think otherwise. As E. L. Bode observes, the notion of the occurrence of a spiritual resurrection while the body remained in the tomb is a peculiarity of modern theology. For the Jews it was the remains of the man in the tomb which were raised; hence, they carefully preserved the bones of the dead in ossuaries until the eschatological resurrection. There can be no doubt that both Paul and the early Christian formula he cites pre-suppose the existence of the empty tomb.

The dating of the resurrection as having occurred “on the third day” implies the empty tomb. The date specified for the resurrection would have been the date that the tomb was discovered to be empty.

The phrase “on the third day” probably points to the discovery of the empty tomb. Very briefly summarized, the point is that since no one actually witnessed the resurrection of Jesus, how did Christians come to date it “on the third day?” The most probable answer is that they did so because this was the day of the discovery of the empty tomb by Jesus’ women followers. Hence, the resurrection itself came to be dated on that day. Thus, in the old Christian formula quoted by Paul we have extremely early evidence for the existence of Jesus’ empty tomb.

A few quotes from atheist historians not from Dr. Craig’s article: (thanks to Eric of Ratio Christi OSU)

Michael Goulder (Atheist NT Prof. at Birmingham) “…it goes back at least to what Paul was taught when he was converted, a couple of years after the crucifixion.” [“The Baseless Fabric of a Vision,” in Gavin D’Costa, editor, Resurrection Reconsidered (Oxford, 1996), 48.]

Gerd Lüdemann (Atheist Prof of NT at Göttingen): “…the elements in the tradition are to be dated to the first two years after the crucifixion of Jesus…not later than three years… the formation of the appearance traditions mentioned in I Cor.15.3-8 falls into the time between 30 and 33 CE.” [The Resurrection of Jesus, trans. by Bowden (Fortress, 1994), 171-72.]

Robert Funk (Non-Christian scholar, founder of the Jesus Seminar): “…The conviction that Jesus had risen from the dead had already taken root by the time Paul was converted about 33 C.E. On the assumption that Jesus died about 30 C.E., the time for development was thus two or three years at most.” [Roy W. Hoover, and the Jesus Seminar, The Acts of Jesus, 466.]

The early pre-Markan burial narrative mentions the empty tomb. This source pre-dates Mark, the earliest gospel. The source has been dated by some scholars to the 40s. For example, the atheist scholar James Crossley dates Mark some time in the 40s. (See the debate below)

The empty tomb story is part of the pre-Markan passion story and is therefore very old. The empty tomb story was probably the end of Mark’s passion source. As Mark is the earliest of our gospels, this source is therefore itself quite old. In fact the commentator R. Pesch contends that it is an incredibly early source. He produces two lines of evidence for this conclusion:

(a) Paul’s account of the Last Supper in 1 Cor. 11:23-5 presupposes the Markan account. Since Paul’s own traditions are themselves very old, the Markan source must be yet older.

(b) The pre-Markan passion story never refers to the high priest by name. It is as when I say “The President is hosting a dinner at the White House” and everyone knows whom I am speaking of because it is the man currently in office. Similarly the pre-Markan passion story refers to the “high priest” as if he were still in power. Since Caiaphas held office from AD 18-37, this means at the latest the pre-Markan source must come from within seven years after Jesus’ death. This source thus goes back to within the first few years of the Jerusalem fellowship and is therefore an ancient and reliable source of historical information.

So we are dealing with very early sources for the empty tomb.

Lack of legendary embellishments

The empty tomb narrative in the gospels lacks legendary embellishments, unlike later 2nd century forgeries that originated outside of Jerusalem.

The eyewitness testimony of the women

This is the evidence that has been the most convincing to skeptics, and to me as well.

The tomb was probably discovered empty by women. To understand this point one has to recall two facts about the role of women in Jewish society.

(a) Woman occupied a low rung on the Jewish social ladder. This is evident in such rabbinic expressions as “Sooner let the words of the law be burnt than delivered to women” and “Happy is he whose children are male, but woe to him whose children are female.”

(b) The testimony of women was regarded as so worthless that they were not even permitted to serve as legal witnesses in a court of law. In light of these facts, how remarkable must it seem that it is women who are the discoverers of Jesus’ empty tomb. Any later legend would certainly have made the male disciples to discover the empty tomb. The fact that women, whose testimony was worthless, rather than men, are the chief witnesses to the empty tomb is most plausibly accounted for by the fact that, like it or not, they were the discoverers of the empty tomb and the gospels accurately record this.

The earliest response from the Jewish high priests assumes the empty tomb

This report from Matthew 28 fulfills the criteria of enemy attestation, although Matthew is not the earliest source we have. Oh, well.

In Matthew 28, we find the Christian attempt to refute the earliest Jewish polemic against the resurrection. That polemic asserted that the disciples stole away the body. The Christians responded to this by reciting the story of the guard at the tomb, and the polemic in turn charged that the guard fell asleep. Now the noteworthy feature of this whole dispute is not the historicity of the guards but rather the presupposition of both parties that the body was missing. The earliest Jewish response to the proclamation of the resurrection was an attempt to explain away the empty tomb. Thus, the evidence of the adversaries of the disciples provides evidence in support of the empty tomb.

Note how careful Craig is not to imply that the guard tradition is historical, because we can’t prove the guard as a “minimal fact”, since it doesn’t pass the standard historical criteria.

See it used in a debate

You can see the arguments made and defended from criticism in this debate with the atheist scholar James Crossley.

This my favorite resurrection debate.

Tim McGrew lectures on undesigned coincidences in the Bible

I have an interesting lecture for you to listen to today, by Dr. Tim McGrew. He is a professor of philosophy at Western Michigan University.

The MP3 file is here.

I do not have a summary of the lecture, but I do have an article that explains what undesigned coincidences are.

Lydia McGrew explains the concept of undesigned coincidences on her blog:

It is a cumulative case argument that the Gospels reflect, to an important extent, independent knowledge of actual events. Please note that this argument is quite independent of one’s preferred answer to the synoptic question. That is to say, even if, e.g., Mark was the first Gospel and others had access to Mark and show signs of literary dependence on Mark, the argument from undesigned coincidences provides evidence for independent knowledge of real events among the Gospel writers.
