The authors of the gospels of Mark and Luke knew eyewitnesses to the life of Jesus

1 Comment

Were the authors of the gospels of Mark and Luke connected to eyewitnesses to the life of Jesus? Well, it turns out that there are good reasons to think that Mark was linked to the eyewitness Peter, and Luke was linked to Paul, who had a post-mortem appearance of Jesus in 1 Cor 15:8, and who met with Peter and James in Galatians 1 and again in Galatians 2.

There is a list of evidence for Peter’s influence on Mark on the Cold Case Christianity blog.

Here’s my favorite one from the list:

Peter’s Embarrassments Have Been Omitted

There are many details in the Gospel of Mark consistent with Peter’s special input and influence,including omissions related to events involving Peter. How can Mark be a memoir of Peter if, in fact, the book contains so many omissions of events involving Peter specifically? It’s important to evaluate the entire catalogue of omissions pertaining to Peter to understand the answer here. The vast majority of these omissions involve incidents in which Peter did or said something rash or embarrassing. It’s not surprising these details were omitted by the author who wanted to protect Peter’s standing in the Christian community. Mark was quite discreet in his retelling of the narrative (other Gospel writers who were present at the time do, however, provide details of Peters ‘indiscretions’ in their own accounts. See Cold-Case Christianity for a more detailed explanation).

It makes me laugh to imagine Peter looking over Mark’s shoulder and saying “no, don’t put that in it” and “no, don’t tell them I did that”. Funny! But also very good evidence. The rest of Wallace’s list makes it even more clear.

And what about the gospel of Luke? Well, did you know that the author of Luke’s gospel knew Paul? If you read it carefully, you’ll see that Luke switches from describing history from an “I” perspective to describing things from a “we” perspective in the book of Acts (which he also wrote). Who is the “we” he is talking about?

Here’s famous Christian scholar William Lane Craig to explain:

Now who was this author we call Luke? He was clearly not an eyewitness to Jesus’s life. But we discover an important fact about him from the book of Acts. Beginning in the sixteenth chapter of Acts, when Paul reaches Troas in modern-day Turkey, the author suddenly starts using the first-person plural: “we set sail from Troas to Samothrace,” “we remained in Philippi some days,” “as we were going to the place of prayer,” etc. The most obvious explanation is that the author had joined Paul on his evangelistic tour of the Mediterranean cities. In chapter 21 he accompanies Paul back to Palestine and finally to Jerusalem. What this means is that the author of Luke-Acts was in fact in first hand contact with the eyewitnesses of Jesus’s life and ministry in Jerusalem.

[…]There is no avoiding the conclusion that Luke-Acts was written by a traveling companion of Paul who had the opportunity to interview eyewitnesses to Jesus’s life while in Jerusalem. Who were some of these eyewitnesses? Perhaps we can get some clue by subtracting from the Gospel of Luke everything found in the other gospels and seeing what is peculiar to Luke. What you discover is that many of Luke’s peculiar narratives are connected to women who followed Jesus: people like Joanna and Susanna, and significantly, Mary, Jesus’s mother.

Was the author reliable in getting the facts straight? The book of Acts enables us to answer that question decisively. The book of Acts overlaps significantly with secular history of the ancient world, and the historical accuracy of Acts is indisputable.

This has recently been demonstrated anew by Colin Hemer, a classical scholar who turned to New Testament studies, in his book The Book of Acts in the Setting of Hellenistic History. [5] Hemer goes through the book of Acts with a fine-toothed comb, pulling out a wealth of historical knowledge, ranging from what would have been common knowledge down to details which only a local person would know. Again and again Luke’s accuracy is demonstrated: from the sailings of the Alexandrian corn fleet to the coastal terrain of the Mediterranean islands to the peculiar titles of local officials, Luke gets it right.

I know a lot of people (like my Dad) read the Bible devotionally, looking for feelings or trying to “get right with God” so they get blessings. But I think it’s helpful to look at things from an evidential point of view – how am I going to make a case for this? When you look at things from that perspective, the Bible gets a whole lot more interesting. And you can talk about it with non-Christians when you know about these interesting details.

William Lane Craig answers: how can the four gospels be independent sources?

3 Comments

Previously, I blogged about the historical criteria that historians use to evaluate documents. One of the criteria is “multiple independent sources”. If a story is reported in multiple independent sources, then historians are more likely to evaluate it as historically accurate. But how about the four gospels? Are they independent sources? The answer might not be what you expect.

Here’s how the question was put to Dr. Craig:

The latest video, “Did Jesus Rise From the Dead,” is especially compelling, but I had a question about it. In the part one video, you cite as evidence, the Gospels plus Acts and First Corinthians and you refer to them as “independent” and “unconnected” sources. But this isn’t exactly true, is it? After all, two of these books were written by the same author, Luke, and so Luke and Acts are connected by authorship. Furthermore, isn’t it true that much information relayed in Matthew and Luke were taken from Mark? This two facts would make it untrue to call the Gospels “independent” and “unconnected” would they not?

Here’s the video he’s talking about:

Dr. Craig answers the question in his latest question of the week. I think this answer is important for those who aren’t aware of how the gospels are organized.

He writes:

The objection is based on a simple misunderstanding. It assumes that the sources I’m referring to are the books of the New Testament.  But that’s not what I’m talking about.

New Testament critics have identified a number of sources behind the New Testament, sources on which the New Testament authors drew. For example, Matthew and Luke drew not only upon Mark as a source but also upon a source which scholars designate “Q,” which appears to have been a source containing Jesus’ sayings or teachings. Thus, if you could show that a saying in Matthew or Luke appears in both Mark and Q, that would count as multiple, independent attestation.

What does this mean? It means that although there is overlap between Matthew and Luke, called “Q”, there are actually three independent sources there: Matthew’s source, called M. Luke’s source, called L. And the material common to Matthew and Luke, which therefore PRE-DATES Matthew and Luke, called Q.

Dr. Craig lists out several independent sources in his full reply:

  1. the pre-Markan Passion story used by Mark
  2. the rest of the gospel of Mark has a source
  3. Matthew’s source (M)
  4. Luke’s source (L)
  5. John’s gospel which is very different from Mark, Luke and Matthew
  6. the sermons in Acts have a source
  7. the early creed found in Paul’s 1 Corinthians 15

So if you are trying to lay out something from the New Testament, and you can find it in two of these sources, and at least one of them is very early, you’re in pretty good shape.

You can watch more of Dr. Craig’s videos in his playlist, here. These are especially useful for people who want to get the overall scope of the battlefield before deciding where to focus in study. Everybody should know about all of these arguments regardless of where you choose to specialize.

William Lane Craig on the unexpected applicability of mathematics to nature

Leave a comment

 

You might remember that Dr. Craig used a new argument in his debate with Lawrence Krauss in Melbourne, Australia.

My notes on the debate record it thus:

The unreasonable effectiveness of mathematics:

  • The underlying structure of nature is mathematical – mathematics is applicable to nature
  • Mathematical objects can either be abstract objects or useful fiction
  • Either way, there is no reason to expect that nature should be linked to abstract objects or fictions
  • But a divine mind that wants humans to understand nature is a better explanation for what we see

And now Dr. Craig has expanded on it in the Q&A section of his Reasonable Faith web site.

The question:

Dear Dr Craig

Firstly can I thank you for all your work. My faith in Christ has been enormously strengthened through studying your work in apologetics in particular and I have grown in confidence in my Christian witness.

My question relates to numbers and mathematics as a whole. On the Defenders podcast you state that as God is the only self-existent, necessary being, numbers and mathematical objects, whilst being useful, don’t actually exist as these too would exist necessarily and independently of God. If this is the case, how can it be that mathematics is so easily applied to the natural world? Surely if mathematics only existed in our minds, we would expect to see no correlation between it and how the physical world actually is?

Excerpt from the answer:

As philosopher of mathematics Mary Leng points out, for the non-theistic realist, the fact that physical reality behaves in line with the dictates of acausal mathematical entities existing beyond space and time is “a happy coincidence” (Mathematics and Reality [Oxford: Oxford University Press, 2010], p. 239). Think about it: If, per impossibile, all the abstract objects in the mathematical realm were to disappear overnight, there would be no effect on the physical world. This is simply to reiterate that abstract objects are causally inert. The idea that realism somehow accounts for the applicability of mathematics “is actually very counterintuitive,” muses Mark Balaguer, a philosopher of mathematics. “The idea here is that in order to believe that the physical world has the nature that empirical science assigns to it, I have to believe that there are causally inert mathematical objects, existing outside of spacetime,” an idea which is inherently implausible (Platonism and Anti-Platonism in Mathematics [New York: Oxford University Press, 1998], p. 136).

By contrast, the theistic realist can argue that God has fashioned the world on the structure of the mathematical objects. This is essentially what Plato believed. The world has mathematical structure as a result.

This argument was also made by mechanical engineering professor Walter Bradley in a lecture he gave on scientific evidence for an intelligent designer. You can read an essay that covers some of the material in that lecture at Leadership University.

Excerpt:

The physical universe is surprising in the simple mathematical form it assumes. All the basic laws of physics and fundamental relationships can be described on one side of one sheet of paper because they are so few in number and so simple in form (see table 1.1).

[…]It has been widely recognized for some time that nature assumes a form that is elegantly described by a relatively small number of simple, mathematical relationships, as previously noted in table 1.1. None of the various proposals presented later in this chapter to explain the complexity of the universe address this issue. Albert Einstein in a letter to a friend expressed his amazement that the universe takes such a form (Einstein 1956), saying:

You find it strange that I consider the comprehensibility of the world to the degree that we may speak of such comprehensibility as a miracle or an eternal mystery. Well, a priori one should expect a chaotic world which cannot be in any way grasped through thought. . . . The kind of order created, for example, by Newton’s theory of gravity is of quite a different kind. Even if the axioms of the theory are posited by a human being, the success of such an enterprise presupposes an order in the objective world of a high degree which one has no a priori right to expect. That is the “miracle” which grows increasingly persuasive with the increasing development of knowledge.

Alexander Polykov (1986), one of the top physicists in Russia, commenting on the mathematical character of the universe, said: “We know that nature is described by the best of all possible mathematics because God created it.” Paul Davies, an astrophysicist from England, says, “The equations of physics have in them incredible simplicity, elegance and beauty. That in itself is sufficient to prove to me that there must be a God who is responsible for these laws and responsible for the universe” (Davies 1984). Successful development of a unified field theory in the future would only add to this remarkable situation, further reducing the number of equations required to describe nature, indicating even further unity and integration in the natural phenomena than have been observed to date.
