Is the definition of atheism “a lack of belief in God”?

I have a key that will unlock a puzzling mystery
I have a key that will unlock a puzzling mystery

First, let’s see check with the Stanford University Encyclopedia of Philosophy:

‘Atheism’ means the negation of theism, the denial of the existence of God.

Stanford University is one of the top 5 universities in the United States, so that’s a solid definition. To be an atheist is to be a person who makes the claim that, as a matter of FACT, there is no intelligent agent who created the universe. Atheists think that there is no God, and theists think that there is a God. Both claims are objective claims about the way the world is out there, and so both sides must furnish forth arguments and evidence as to how they are able to know what they are each claiming.

Philosopher William Lane Craig has some thoughts on atheism, atheists and lacking belief in God in this reply to a questioner.

Question:

In my discussions with atheists, they  are using the term that they “lack belief in God”. They claim that this is different from not believing in God or from saying that God does not exist. I’m not sure how to respond to this. It seems to me that its a silly word-play and is logically the same as saying that you do not believe in God.
What would be a good response to this?
Thank you for your time,

Steven

And here is Dr. Craig’s full response:

Your atheist friends are right that there is an important logical difference between believing that there is no God and not believing that there is a God.  Compare my saying, “I believe that there is no gold on Mars” with my saying “I do not believe that there is gold on Mars.”   If I have no opinion on the matter, then I do not believe that there is gold on Mars, and I do not believe that there is no gold on Mars.  There’s a difference between saying, “I do not believe (p)” and “I believe (not-p).”   Logically where you place the negation makes a world of difference.

But where your atheist friends err is in claiming that atheism involves only not believing that there is a God rather than believing that there is no God.

There’s a history behind this.  Certain atheists in the mid-twentieth century were promoting the so-called “presumption of atheism.” At face value, this would appear to be the claim that in the absence of evidence for the existence of God, we should presume that God does not exist.  Atheism is a sort of default position, and the theist bears a special burden of proof with regard to his belief that God exists.

So understood, such an alleged presumption is clearly mistaken.  For the assertion that “There is no God” is just as much a claim to knowledge as is the assertion that “There is a God.”  Therefore, the former assertion requires justification just as the latter does.  It is the agnostic who makes no knowledge claim at all with respect to God’s existence.  He confesses that he doesn’t know whether there is a God or whether there is no God.

But when you look more closely at how protagonists of the presumption of atheism used the term “atheist,” you discover that they were defining the word in a non-standard way, synonymous with “non-theist.”  So understood the term would encompass agnostics and traditional atheists, along with those who think the question meaningless (verificationists).  As Antony Flew confesses,

the word ‘atheist’ has in the present context to be construed in an unusual way.  Nowadays it is normally taken to mean someone who explicitly denies the existence . . . of God . . . But here it has to be understood not positively but negatively, with the originally Greek prefix ‘a-’ being read in this same way in ‘atheist’ as it customarily is in . . . words as ‘amoral’ . . . . In this interpretation an atheist becomes not someone who positively asserts the non-existence of God, but someone who is simply not a theist. (A Companion to Philosophy of Religion, ed. Philip Quinn and Charles Taliaferro [Oxford:  Blackwell, 1997], s.v. “The Presumption of Atheism,” by Antony Flew)

Such a re-definition of the word “atheist” trivializes the claim of the presumption of atheism, for on this definition, atheism ceases to be a view.  It is merely a psychological state which is shared by people who hold various views or no view at all.  On this re-definition, even babies, who hold no opinion at all on the matter, count as atheists!  In fact, our cat Muff counts as an atheist on this definition, since she has (to my knowledge) no belief in God.

One would still require justification in order to know either that God exists or that He does not exist, which is the question we’re really interested in.

So why, you might wonder, would atheists be anxious to so trivialize their position?  Here I agree with you that a deceptive game is being played by many atheists.  If atheism is taken to be a view, namely the view that there is no God, then atheists must shoulder their share of the burden of proof to support this view.  But many atheists admit freely that they cannot sustain such a burden of proof.  So they try to shirk their epistemic responsibility by re-defining atheism so that it is no longer a view but just a psychological condition which as such makes no assertions.  They are really closet agnostics who want to claim the mantle of atheism without shouldering its responsibilities.

This is disingenuous and still leaves us asking, “So is there a God or not?”

So there you have it. We are interested in what both sides know and what reasons and evidence they have to justify their claim to know. We are interested in talking to people who make claims about objective reality, not about themselves, and who then go on to give reasons and evidence to support their claims about objective reality. There are atheists out there that do make an objective claim that God does not exist, and then support that claim with arguments and evidence. Those are good atheists, and we should engage in rational conversations with them. But clearly there are some atheists who are not like that. How should we deal with these “subjective atheists”?

Dealing with subjective atheists

How should theists respond to people who just want to talk about their psychological state? Well, my advice is to avoid them. They are approaching religion irrationally and non-cognitively – like the person who enters a physics class and says “I lack a belief in the gravitational force!”.  When you engage in serious discussions with people about God’s existence, you only care about what people know and what they can show to be true. We don’t care about a person’s psychology.

Dealing with persistent subjective atheists

What happens when you explain all of that to a subjective atheist who continues to insist that you listen to them repeat over and over “I lack a belief in God, I lack a belief in God”? What if you tell them to make the claim that God does not exist, and then support it with arguments and evidence, but instead they keep leaving comments on your blog telling you again and again about their subjective state of mind: “I lack a belief in cupcakes! I lack a belief in icebergs!” What if they keep e-mailing you and threatening to expose you on Twitter for refusing to listen to them, or denounce you via skywriting: “Wintery Knight won’t listen to me! I lack a belief in crickets!”. I think at this point you have to give up and stop talking to such a person.

And that’s why I moderate and filter comments on this blog. There are uneducated people out there with access to the Internet who want attention, but I am not obligated to give it to them. And neither are you. We are not obligated to listen to abusive people who don’t know what they are talking about. I do post comments from objective atheists who make factual claims about the objective world, and who support those claims with arguments and evidence. I am not obligated to post comments from people who refuse to make objective claims or who refuse to support objective claims with arguments and evidence. And I’m not obligated to engage in discussions with them, either.

Christian woman finds a way to discuss her faith with non-Christians

I found an interesting article where a Christian woman explains how she used to share her testimony with non-Christians. But that wasn’t working. So she decided to try something different.

She writes:

I’ll never forget the first time I shared my personal testimony with a non-Christian.

When the opportunity arose and I shared my story with an unbelieving friend, she replied, “That’s so cool. I’m so happy you found something that works for you.”

For me?

“It’s not about what works for me,” I said, trying to hide my discouragement. “It’s about what’s true for everyone.”

“That doesn’t make sense,” she responded. “That’s your experience, not mine. I had a similar revelation when I realized I could leave the church, and I’ve become a better person for my decision. Just as you were freed from your heaviest burdens by finding God, I was freed from mine by leaving God behind.”

I was devastated but I chalked it up to my friend’s hardheartedness. I decided to shake the dust off my feet and look forward to the next opportunity.

But time after time of sharing my testimony resulted in similar responses. People expressed enthusiasm that I was happy, that Christianity worked for me, and that I had “found my niche.” Yet no one considered my experience as anything more than just that—my own personal experience.

[…]I had been taught that sharing what God had done in my life was the ideal way to witness to non-Christians. A personal testimony was interesting yet non-confrontational, compelling but inoffensive. And yet, despite having shared my testimony with dozens of unbelievers, not a single person felt challenged to consider the truth claims of Christianity.

She noticed that her approach wasn’t actually in the Bible. There was a different approach being demonstrated by Jesus, and later by his disciples.

She writes:

When Jesus called his first disciples, he taught truth and provided evidence (miracles) to support his claims, then he asked people to follow him (Luke 5:1–11). In fact, this was his method whenever he went into new regions (see Luke 4:14–44; John 4:7–26). People decided to follow Jesus not on blind faith or a subjective feeling, but based on the evidence they had seen and heard.[i]

Jesus also used evidence to assuage the doubts of even those who had been with him a long time. John the Baptist was Jesus’ cousin, who leapt in the womb during Mary’s visit (Luke 1:39–45), baptized Jesus in the Jordan River, heard God’s voice from heaven, and saw the Holy Spirit descend on Jesus in bodily form like a dove (Luke 3:21–22). Yet when John experienced unexpected suffering, he began to doubt.

Jesus didn’t respond as many do today, by insisting that John “just believe” or “have faith” or “prayer harder.” Rather, he responded with more evidence, saying, “Go and tell John what you hear and see: the blind receive their sight and the lame walk, lepers are cleansed and the deaf hear, and the dead are raised up, and the poor have good news preached to them. And blessed is the one who is not offended by me.” (Matt. 11:2–6).

[…]At Pentecost, the apostle Peter offered signs and wonders, fulfilled prophecy, and relayed eyewitness testimony to persuade people from all over the Roman Empire that the most reasonable explanation for what they were seeing was not morning drunkenness, but a risen Messiah (Acts 2:1–41).

On his missionary journeys, the apostle Paul reasoned with the Jews from the Scriptures, explaining and proving that Jesus was the Messiah who needed to suffer and rise from the dead (Acts 17:1–3, 17). And he reasoned with the Gentiles from outside the Scriptures, making a case with their own accepted beliefs to convince them (Acts 17:17–34).

In fact, in describing his mission, Paul told the Philippians, “I am put here for the defense of the gospel” (1:7, 16). This word translated defense is the same word from which we get our English word “apologetics,” meaning to make reasoned arguments or to provide evidence as justification. Using this same word, Peter commanded believers to “always [be] prepared to make a defense to anyone who asks you for a reason for the hope that is in you”(1 Pet. 3:15).

So, she decided to dump the testimony approach, and try the Biblical approach. But she had to change it a little bit, since she couldn’t perform miracles herself:

We are not eyewitnesses to Jesus’s life and resurrection, but we have the accounts of those who were. We don’t typically see miracles, but we have millennia of biblical scholarship and archaeology that provide reasons to believe the accounts are trustworthy. We don’t often hear God speaking audibly or see him parting seas, but we have significant scientific evidence that shows the universe had a beginning, and millennia of observation to confirm the scientific principle that everything that begins to exist has a cause.

I think a lot of Christians never move on from approach she described that wasn’t getting results. And there’s a reason for that – studying evidence is hard work. But I can tell you from my experience as a software engineer, there is no better way to convince other people to adopt your view than to show them working code that produces results. If they have a prototype, they will adopt your design. Similarly with Christianity. If you have evidence, then you will be persuasive.

When talking about spiritual things with non-Christians, always remember the joke about the two men walking in the woods who meet a bear. One man starts to put on his running shoes. The other man says “what are you doing? you can’t outrun a bear!” And the first man says “I don’t have to. I only have to outrun you”. It’s the same with apologetics. You don’t have to be William Lane Craig to talk about your faith to non-Christians. You just have to know more than your non-Christian opponent knows about evidence.

The way things are going these days with the public schools and the mainstream news media, this is actually pretty easy to do. One or two introductory books on the origin of the universe, the fine-tuning for intelligent life, the origin of biological information, the origin of body plans, the historical reliability of the New Testament, the minimal facts case for the resurrection, etc. will do the job. You might need another one on philosophical challenges like evil, suffering, divine hiddenness, etc. But we’re talking no more than 5 books, and you’ll be effective in the vast majority of your conversations. If you can only get one book, I like Sean McDowell and Jonathan Morrow’s “Is God Just a Human Invention?” best.

William Lane Craig on the unexpected applicability of mathematics to nature

Christianity and the progress of science
Christianity and the progress of science

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.

The whole paper that started this off is called “The Unreasonable Effectiveness of Mathematics”, and it is a must read for advanced Christian defenders. You can read the whole thing here.

Correcting four myths about the history of the Crusades

Crusader
Crusader

Here is an interesting article from Intercollegiate Studies Institute.

Intro:

The verdict seems unanimous. From presidential speeches to role-playing games, the crusades are depicted as a deplorably violent episode in which thuggish Westerners trundled off, unprovoked, to murder and pillage peace-loving, sophisticated Muslims, laying down patterns of outrageous oppression that would be repeated throughout subsequent history. In many corners of the Western world today, this view is too commonplace and apparently obvious even to be challenged.

But unanimity is not a guarantee of accuracy. What everyone “knows” about the crusades may not, in fact, be true. From the many popular notions about the crusades, let us pick four and see if they bear close examination.

The four myths:

  • Myth #1: The crusades represented an unprovoked attack by Western Christians on the Muslim world.
  • Myth #2: Western Christians went on crusade because their greed led them to plunder Muslims in order to get rich.
  • Myth #3: Crusaders were a cynical lot who did not really believe their own religious propaganda; rather, they had ulterior, materialistic motives.
  • Myth #4: The crusades taught Muslims to hate and attack Christians.

Here’s the most obvious thing you should know. The Crusades were defensive actions:

In a.d. 632, Egypt, Palestine, Syria, Asia Minor, North Africa, Spain, France, Italy, and the islands of Sicily, Sardinia, and Corsica were all Christian territories. Inside the boundaries of the Roman Empire, which was still fully functional in the eastern Mediterranean, orthodox Christianity was the official, and overwhelmingly majority, religion. Outside those boundaries were other large Christian communities—not necessarily orthodox and Catholic, but still Christian. Most of the Christian population of Persia, for example, was Nestorian. Certainly there were many Christian communities in Arabia.

By a.d. 732, a century later, Christians had lost Egypt, Palestine, Syria, North Africa, Spain, most of Asia Minor, and southern France. Italy and her associated islands were under threat, and the islands would come under Muslim rule in the next century. The Christian communities of Arabia were entirely destroyed in or shortly after 633, when Jews and Christians alike were expelled from the peninsula.6 Those in Persia were under severe pressure. Two-thirds of the formerly Roman Christian world was now ruled by Muslims.

What had happened? Most people actually know the answer, if pressed—though for some reason they do not usually connect the answer with the crusades. The answer is the rise of Islam. Every one of the listed regions was taken, within the space of a hundred years, from Christian control by violence, in the course of military campaigns deliberately designed to expand Muslim territory at the expense of Islam’s neighbors. Nor did this conclude Islam’s program of conquest. The attacks continued, punctuated from time to time by Christian attempts to push back. Charlemagne blocked the Muslim advance in far western Europe in about a.d. 800, but Islamic forces simply shifted their focus and began to island-hop across from North Africa toward Italy and the French coast, attacking the Italian mainland by 837. A confused struggle for control of southern and central Italy continued for the rest of the ninth century and into the tenth. In the hundred years between 850 and 950, Benedictine monks were driven out of ancient monasteries, the Papal States were overrun, and Muslim pirate bases were established along the coast of northern Italy and southern France, from which attacks on the deep inland were launched. Desperate to protect victimized Christians, popes became involved in the tenth and early eleventh centuries in directing the defense of the territory around them.

If you asked me what are the two best books on the Crusades, I would answer God’s Battalions: The Case for the Crusades by Baylor professor Rodney Stark and The Concise History of the Crusades by Professor Thomas F. Madden. If you get this question a lot from atheists, then I recommend you pick these up. Anything by Rodney Stark is useful for Christians, in fact.

Why do so many atheist historians think that 1 Corinthians 15 is reliable history?

Investigation in progress
Investigation in progress

Which passage of the Bible is the favorite of Christians who like to defend the Christian worldview? I don’t mean which one is most inspirational… I mean “which one is the most useful for winning arguments?” Well, when it comes to the historical Jesus, the most important passage has to be 1 Corinthians 15:3-7.

The tradition in 1 Corinthians 15 is an early creed that was received from the eyewitnesses Peter and John when Paul visited them several times in Jerusalem, as documented in Galatians 1 and 2, where Paul meets the eyewitnesses. And of course, Paul records his own eyewitness experience, documented in 1 Cor 15:8.

So, is this passage accepted as historically reliable by all ancient historians? Or only by the Bible-believing ones?

Here’s something posted by Dr. William Lane Craig about the 1 Corinthians 15 passage:

The evidence that Paul is not writing in his own hand in I Cor. 15.3-5 is so powerful that all New Testament scholars recognize that Paul is here passing on a prior tradition. In addition to the fact that Paul explicitly says as much, the passage is replete with non-Pauline characteristics, including, in order of appearance: (i) the phrase “for our sins” using the genitive case and plural noun is unusual for Paul; (ii) the phrase “according to the Scriptures” is unparalleled in Paul, who introduces Scriptural citations by “as it is written”; (iii) the perfect passive verb “has been raised” appears only in this chapter and in a pre-Pauline confessional formula in II Tim. 2.8; (iv) the phrase “on the third day” with its ordinal number following the noun in Greek is non-Pauline; (v) the word “appeared” is found only here and in the confessional formula in I Tim. 3.16; and (vi) “the Twelve” is not Paul’s nomenclature, for he always speaks of the twelve disciples as “the apostles.”

Now the visit during which Paul may have received this tradition is the visit you mention three years after his conversion on the road to Damascus (Gal. 1.18). This puts the tradition back to within the first five years after Jesus’ death in AD 30. So there’s not even an apparent inconsistency with Paul’s appropriating the language of the formula to encapsulate the Gospel he was already preaching during those first three years in Damascus.

Ancient historian Gary Habermas loves to read non-Christian scholars… and then he writes about what THEY think about Jesus in peer-reviewed articles, published in academic journals. Let’s look at this one: Dialog: A Journal of Theology, Vol. 45; No. 3 (Fall, 2006), pp. 288-297; published by Blackwell Publishing, UK.

He writes:

(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]

This is important:

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).

He’s an eyewitness (verse 8), and he met with the other eyewitnesses, James and Peter. 1 Corinthians is early. Galatians is early. The creed is extremely early – right after the events occurred. There was no time for legends to develop.

And atheistic / critical historians agree, the creed is reliable:

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.

Now, some of the people he lists are really biased against the supernatural, and they really hate the idea that the claims of Christianity exclude other religions. And yet they don’t deny the historical reliability of 1 Corinthians 15, or that it is based on eyewitness testimony.

That’s why when you watch debates about the historical Jesus, you see skeptical historians like Bart Ehrman, Gerd Ludemann, James Crossley, Michael Goulder, etc. accepting that the disciples thought they saw Jesus after his death. They’re not just being nice to Dr. Craig when they give him that. They are forced to accept it, because it passes the historical tests. Every Christian ought to be aware of which passages of the New Testament are seen by the broad spectrum of ancient historians as “historical”, regardless of their various biases. You can believe everything in the Bible. But when you debate non-Christians, you have to use the historical core of Christianity which successfully passes historical analysis.

You can see the creed used as evidence in the debate between James Crossley and William Lane Craig.
