Why Christian parents get nervous about evidence when discussing Christianity

Homeschooling mother Dr. Lydia McGrew explains why Bible-believing Christians are uneasy with the use of evidence on her blog What’s Wrong With The World. (H/T Eric Chabot)

Excerpt:

4) The idea that, if a young person gets deeply interested in Christian evidence, he will go out on the Internet (or at his public high school or secular college) seeking giants to slay and will get overwhelmed. Again, this worry has merit as a sociological matter. That can certainly happen.

That is why we should say loud and clear to Christians interested in this topic: Don’t do that! What do I mean? Just this: Being committed to investigating the evidence for Christianity does not mean that one has to find out every possible thing that anyone has ever said about or against Christianity and know the answer to it. That would be impossible because of the sheer bulk of (ultimately unpersuasive) objections which skeptics can bring up as though they were real problems.

In this context the words of George Horne, an 18th century bishop, from his Letters on Infidelity, are wise and helpful. (Emphasis added.)

In the thirty sections of their pamphlet, they have produced a list of difficulties to be met with in reading the Old and New Testament. Had I been aware of their design, I could have enriched the collection with many more, at least as good, if not a little better. But they have compiled, I dare say, what they deemed the best, and, in their own opinion, presented us with the essence of infidelity in a thumb-phial, the very fumes of which, on drawing the cork, are to strike the bench of bishops dead at once. Let not the unlearned Christian be alarmed, “as though some strange thing had happened to him,” and modern philosophy had discovered arguments to demolish religion, never heard of before. The old ornaments of deism have been “broken off” upon this occasion, “and cast into the fire, and there came out this calf.” These same difficulties have been again and again urged and discussed in public; again and again weighed and considered by learned and sensible men, of the laity as well as the clergy, who have by no means been induced by them to renounce their faith.

Many and painful are the researches sometimes necessary to be made, for settling points of that kind. Pertness and ignorance may ask a question in three lines, which it will cost learning and ingenuity thirty pages to answer. When this is done, the same question shall be triumphantly asked again the next year, as if nothing had ever been written upon the subject.

And a bit later:

5) The unspoken fear that Christianity cannot stand up to scrutiny and doesn’t really have good evidential support.

Here I do not blame the parents, but not because I share the unspoken fear. I do not blame them, because in most cases no one has ever taught them otherwise. How many pastors and priests have really taught apologetics to their congregations, or even offered such studies as an option? Too few. How many courses on sharing your faith have explicitly taught people not to get involved in responding to questions and objections but just to “share their experience” because “no one can argue with that”? Too many. It’s no wonder then that the congregation comes away with the sneaking suspicion that our Christian faith is no better grounded than Mormonism and that we, like they, must depend chiefly on the burning in the bosom.

And one can always push the blame further back. Perhaps the pastors weren’t taught Christian evidences at their seminaries.

In fact, I would not be surprised if all too many theologians who give high-falutin’ rationalizations for being anti-evidentialist are actually making a virtue out of what they deem to be a necessity. Since they don’t think Christian faith is founded on fact, they might as well make up some profound-sounding theological theory that tells us that it shouldn’t be.

When Nathanael asks Philip, “Can any good thing come out of Nazareth?” Philip simply says, “Come and see.” (John 1:46) And he brings him to Jesus. If you as a parent or mentor to the young are opposed to the study of Christian evidences partly because deep down you suspect that they aren’t very good, I can only say to you as well, “Come and see.”

I blogged about this tendency of church leaders to make a virtue out of laziness and ignorance before.

Here’s a snip:

Suppose a pastor or campus group leader wants to avoid having to learn physics and cosmology, or the minimum facts case for the resurrection, or how to respond to apparently gratuitous suffering, or the problem of religious pluralism. Suppose he thinks that Christianity, if it is about anything, is about his feeling happy and comfortable with a minimum of effort and work. So, he diligently avoids reading apologetics, because learning evidence is hard work. He avoids watching debates on God’s existence and the resurrection, because this is hard work. He avoids conversations with people who do study these things, and implies that there is something wrong with them for studying these things. He endeavors to conceal his laziness and ignorance and cowardice from his flock with much pious God-talk and fervent praise-hymn-singing.

Eventually, some member of his church asks him to go for lunch with an actual non-Christian family member. The pastor agrees and when he meets the unbelieving family member, he has nothing at all to say about typical challenges that unbelievers face. He has no knowledge of evolution, the problem of evil, the hiddenness of God, or the hallucination theory. He has never read a single atheist, and never read a single piece of evidence to refute them from Christian scholars. He lacks humility, refusing to admit that other Christian scholars may know more than he does because they have studied other areas. Needless to say, he fails to defend God’s reputation to the non-Christian. What will he say to the members of his flock about his failure? How will he justify his obstinate refusal to do what everyone else in the Bible does when confronting non-believers?

Well, consider this review of a recent book that defends the Gospels and the historicity of the resurrection by one such fideist pastor.

He writes:

There are, however, two significant shortcomings to the book.

First, Cold-Case Christianity places far too much emphasis on the role of extrabiblical sources. No doubt there is a legitimate role for biblical archaeology and extrabiblical writing from antiquity. Christianity is, after all, a faith firmly rooted in human history. But there is a grave danger when truth is suspended because of an apparent lack of corroboration from extrabiblical sources. And Wallace, I’m afraid, wanders too close to this dark side of apologetics.

All of chapter 12, for instance, is devoted to proving the Gospels have external corroborative evidence—“evidence that are independent of the Gospel documents yet verify the claims of the text” (183). Wallace then addresses the historicity of the pool of Bethesda and makes another worrying statement: “For many years, there was no evidence for such a place outside of John’s Gospel. Because Christianity makes historical claims, archaeology ought to be a tool we can use to see if these claims are, in fact, true” (201-202, emphasis added).

In other words, Wallace seems to suggest we cannot affirm the truth of the Gospel accounts without the stamp of approval from archaeology and other extrabiblical sources. Such reasoning is dangerous, not least because it cannot affirm the inerrancy of the Bible. But also, it places the final court of appeal in the realm of extrabiblical sources rather than of God’s all-sufficient, all-powerful Word.

That is a textbook definition of fideism – that belief is somehow more pious and praiseworthy the less evidence we have. And the best way to have less evidence is to study nothing at all, but to just make a leap-of-faith in the dark. Of course, a leap-of-faith can land you anywhere – Islam, Mormonism. Presumably this pastor is like the Mormons who eschew all evidence and prefer to detect the truth of Mormonism by “the burning of the bosom” which happens when people read the all-sufficient, all-powerful Book of Mormon. His view of faith is identical to theirs, and 180 degrees opposed to the Bible. He has made his leap-of-faith, and that leap-of-faith is not accountable to arguments and evidence. His faith is private and personal, based on his own feelings. He considers it blasphemous to have to demonstrate what he believes to those who disagree with him. Where is this in the Bible? It’s nowhere. But it is everywhere in anti-intellectual Christian circles.

[…]I think that Christians are much better off following the example of authentic Christian pastors like R.C. Sproul, who, in a conference on evangelism, invited Dr. Stephen C. Meyer to present multiple lines of evidence from mainstream science to establish the existence of God. The only reason not to take this approach is laziness, which leads to ignorance, which leads to cowardice. And failure. It is pastors like Pastor Bungle above who are responsible for the great falling away from Christianity that we are seeing when we look at young people. Pastors who pride themselves in refusing to connecting the Bible to the real world, with evidence and with policy analysis, are causing young people to abandon the faith.

I think that many people who reject Christianity can point to a general impression that they got from Pastor Bungle and his ilk that faith is somehow different from other areas of knowledge and that it was morally praise worthy to insulate faith from critical thinking and evidence. Pastor Bungle could never justify his view by using the Bible, but a lot of church leaders have that view regardless of whether it’s Biblical or not.

The really troubling thing that I see again and again in the church is when pastors base all of their opposition to behaviors like abortion and gay marriage on Christianity. This effectively makes it impossible to do anything about these issues in the public square, because Christians are then taught to have nothing persuasive to say on these issues to non-Christians. It’s like pastors are more interested in striking a pious pose with their congregations instead of studying secular arguments and evidence so they can equip Christians to actually solve the problem.

Review of evidential apologetics book by pastor shows where church needs to improve

Theology that hits the spot
Theology that hits the spot

Whenever I talk to Christians, I find that they hold one of two views about what faith is.

The first view of faith is the Biblical view of faith as active trust in propositions we know to be true, because we have reasons and evidence to believe those propositions. This view is not only rooted in the Bible, but it extends through Augustine and Aquinas to the present day. I have written about this view of faith before, and quoted many theologians in support of it. In the Bible, people use miracles as a sign in order to convince skeptics. For example, Peter appeals to the resurrection in Acts 2. The Bible teaches that faith is active trusting based on evidence.

The second view is blind faith. This view is nowhere in the Bible, and this view asserts that becoming a Christian is a leap-of-faith in the dark against all the evidence. This view not only minimizes evidence, but it actually opposes presenting evidence to unbelievers and skeptics in the way that the Bible teaches. This view is nowhere in the Bible, and it was not the method used by Jesus or his followers. It is an unBiblical way of viewing faith, but it is very popular in some circles of Christianity. It is also popular among atheists, because this is what many Christian leaders and pastors tell them that faith is.

Consider this review of a recent book that defends the Gospels and the historicity of the resurrection by one such fideist pastor.

He writes:

There is a good response to this blind-faith pastor on Deeper Waters. Much less angry than my response.

Excerpt:

The dark side of apologetics? Did I somehow step into a Star Wars universe?

Yes. How horrible to show that the Bible is backed up by sources outside of it. How terrible to show that these events did not happen in a vacuum. Thankfully, no one in the Bible took this approach.

Except for the fact that when the gospel was being preached, there were no gospels per se and there were no epistles. Paul told Agrippa that the events done weren’t done in a corner. In other words, investigate the claims for yourself! The early testimony was eyewitness testimony. Sources like Tacitus and others show the eyewitnesses were right! This was not done in a corner! This was done out in the open! Archaeology helps us confirm the biblical writings and shows that unlike the pagan myths, these events were rooted in a place and time. Is there some danger that our faith will be destroyed by outside sources?

It really becomes a fideistic approach. If your worldview is true, you should have no problem putting it to the strictest scrutiny. If it is not, then you will have a problem. No Christian should fear further research into what they believe. No Christian should have a problem with extra-biblical sources. Now I do agree there is a problem with stating that EVERYTHING must be backed extra-biblically. I think this is a prejudice we too often have where nothing in the Bible can be considered historical unless it’s verified somewhere else. A gospel account alone could count as a historical claim itself that can be investigated, and indeed is in NT scholarship, but where we can get extra-biblical evidence, I’m all for it.

[…]Christianity is a faith that is rooted in evidences so we should be able to use evidences to demonstrate it. I have often been told by those of the presuppositional bent that the approach is used all the time in the Bible. The problem is I can’t find one. I get told passages like “The fear of the Lord is the beginning of wisdom.” Yes. It is. Wisdom refers to godly living. It doesn’t refer to confirming the gospel to be true. When I look at the apostles in every case, I see them pointing to evidences.

It is pastors like Pastor Bungle above who are responsible for the great falling away from Christianity that we are seeing when we look at young people. We need pastors who connect the claims of the Christian worldview to evidence.

William Lane Craig discusses faith and reason with university students

This is an interview of Dr. William Lane Craig before college students at the University of Central Florida. (95 minutes)

You can get an MP3 of the lecture here. (33 MB)

Questions from the interviewer: (40 minutes)

  • What started you on his journey of studying faith and reason?
  • How would you define the word “faith”?
  • Are faith and reason compatible? How are they related?
  • How can reasonable faith help us to avoid the two extremes of superstition and nihilism?
  • Who makes the best arguments against the Christian faith?
  • Why are angry atheists like Dawkins and Hitchens more well known than better-informed academic atheists?
  • Does the Bible require Christians to give the unbeliever reasons for their faith?
  • How does faith spur Christians to think carefully about the big questions in life?
  • Should the American church prod churchgoers to develop their minds so they can engage the secular culture?
  • When talking about Christianity intellectually, is there a risk of neglecting the experience of being a Christian?
  • Which Christian apologist has shaped your thinking the most?
  • Which Christian philosopher has shaped your thinking the most?
  • Does the confidence that comes from apologetics undermine humility and reverence?
  • If you had to sketch out a 5 minute case for Christianity, what would you present?
  • Can non-Christians use their reason to arrive at truth?
  • Are there cases where atheists must affirm irrational things in order to remain atheists?
  • Can the universe have existed eternal, so that there is no need to explain who created it?
  • Even if you persuade someone that Christianity is true, does that mean they will live it out?

There is also a long period of questions, many of them hostile, from the audience of students (55 minutes).

  • Haven’t you said nasty things about some atheists? Aren’t you a meany?
  • What do you make of the presuppositional approach to apologetics?
  • Can a person stop being a Christian because of the chances that happen to them as they age?
  • Why did God wait so long after humans appeared to reveal himself to people through Jesus?
  • Can a person be saved by faith without have any intellectual assent to truth?
  • How do you find time for regular things like marriage when you have to study and speak so much?
  • How would you respond to Zeitgeist and parallels to Christianity in Greek/Roman mythology?
  • Do Christians have to assume that the Bible is inerrant and inspired in order to evangelize?
  • If the universe has a beginning, then why doesn’t God have a beginning?
  • Can you name some philosophical resources on abstract objects, Platonism and nominalism?
  • How can you know that Christianity more right than other religions?
  • Should we respond to the problem of evil by saying that our moral notions are different from God’s?
  • Define the A and B theories of time. Explain how they relate to the kalam cosmological argument.
  • How can Christians claim that their view is true in the face of so many world religions?
  • What is the role of emotions in Christian belief and thought?
  • Can evolution be reconciled with Christian beliefs and the Bible?
  • When witnessing person-to-person, should you balance apologetics with personal testimony?
  • Is there a good analogy for the trinity that can help people to understand it? [Note: HE HAS ONE!]
  • How can Christians reconcile God’s omniscience, God’s sovereignty and human free will?

This is a nice introductory lecture that is sure to get Christians to become interested in apologetics. As you watch or listen to it, imagine what the world would be like if every Christian could answer the questions of skeptical college students and professors like Dr. Craig. What would non-Christians think about Christianity if every Christian had studied these issues like Dr. Craig? Why aren’t we making an effort to study these things so that we can answer these questions?

It is really fun to see him fielding the questions from the skeptical university students. My favorite question was from the physics student who sounds really foreign, (at 1:19:00), then you realize that he is a Christian. I do think that Dr. Craig went a little far in accommodating evolution, but I put that down to the venue, and not wanting to get into a peripheral issue.

Six reasons why you should believe in non-physical souls

This podcast is a must-listen. Please take the time to download this podcast and listen to it. I guarantee that you will love this podcast. I even recommended it to my Dad and I almost never do that.

Details:

In this podcast, J. Warner examines the evidence for the existence of the mind (and inferentially, the soul) as he looks at six classic philosophical arguments. Jim also briefly discusses Thomas Nagel’s book, Mind and Cosmos and discusses the limitations of physicalism.

The MP3 file is here. (67 MB, 72 minutes)

Topics:

  • Atheist Thomas Nagel’s latest book “Mind and Cosmos” makes the case that materialism cannot account for the evidence of mental phenomena
  • Nagel writes in this recent New York Times article that materialism cannot account for the reality of consciousness, meaning, intention and purpose
  • Quote from the Nagel article:

Even though the theistic outlook, in some versions, is consistent with the available scientific evidence, I don’t believe it, and am drawn instead to a naturalistic, though non-materialist, alternative. Mind, I suspect, is not an inexplicable accident or a divine and anomalous gift but a basic aspect of nature that we will not understand until we transcend the built-in limits of contemporary scientific orthodoxy.

  • When looking at this question, it’s important to not have our conclusions pre-determined by presupposing materialism or atheism
  • If your mind/soul doesn’t exist and you are a purely physical being then that is a defeater for Christianity, so we need to respond
  • Traditionally, Christians have been committed to a view of human nature called “dualism” – human beings are souls who have bodies
  • The best way* to argue for the existence of the soul is using philosophical arguments

The case:

  • The law of identity says that if A = B’ if A and B have the exact same properties
  • If A = the mind and B = the brain, then is A identical to B?
  • Wallace will present 6 arguments to show that A is not identical to B because they have different properties

Not everyone of the arguments below might make sense to you, but you will probably find one or two that strike you as correct. Some of the points are more illustrative than persuasive, like #2. However, I do find #3, #5 and #6 persuasive.

1) First-person access to mental properties

  • Thought experiment: Imagine your dream car, and picture it clearly in your mind
  • If we invited an artist to come and sketch out your dream car, then we could see your dream car’s shape on paper
  • This concept of your dream car is not something that people can see by looking at your brain structure
  • Physical properties can be physically accessed, but the properties of your dream care and privately accessed

2) Our experience of consciousness implies that we are not our bodies

  • Common sense notion of personhood is that we own our bodies, but we are not our bodies

3) Persistent self-identity through time

  • Thought experiment: replacing a new car with an old car one piece at a time
  • When you change even the smallest part of a physical object, it changes the identity of that object
  • Similarly, your body is undergoing changes constantly over time
  • Every cell in your body is different from the body you had 10 years ago
  • Even your brain cells undergo changes (see this from New Scientist – WK)
  • If you are the same person you were 10 years ago, then you are not your physical body

4) Mental properties cannot be measured like physical objects

  • Physical objects can be measured (e.g. – use physical measurements to measure weight, size, etc.)
  • Mental properties cannot be measured

5) Intentionality or About-ness

  • Mental entities can refer to realities that are physical, something outside of themselves
  • A tree is not about anything, it just is a physical object
  • But you can have thoughts about the tree out there in the garden that needs water

6) Free will and personal responsibility

  • If humans are purely physical, then all our actions are determined by sensory inputs and genetic programming
  • Biological determinism is not compatible with free will, and free will is required for personal responsibility
  • Our experience of moral choices and moral responsibility requires free will, and free will requires minds/souls

He spends the last 10 minutes of the podcast responding to naturalistic objections to the mind/soul hypothesis.

*Now in the podcast, Wallace does say that scientific evidence is not the best kind of evidence to use when discussing this issue of body/soul and mind/brain. But I did blog before about two pieces of evidence that I think are relevant to this discussion: corroborated near-death experiences and mental effort.

You might remember that Dr. Craig brought up the issue of substance dualism, and the argument from intentionality (“aboutness”), in his debate with the naturalist philosopher Alex Rosenberg, so this argument about dualism is battle-ready. You can add it to your list of arguments for Christian theism along with all the other arguments like the Big Bang, the fine-tuning, the origin of life, stellar habitability, galactic habitability, irreducible complexity, molecular machines, the Cambrian explosion, the moral argument, the resurrection, biological convergence, and so on.

Does God’s omniscience conflict with human free will?

Here’s the setup for the question, from Come Reason ministries.

Excerpt:

Hello,

Christian doctrine holds that God is all knowing (1 John 3:20), and humans have free will (Deuteronomy 30:19 is my favorite example). however, at my favorite apologetics debate board, I have seen skeptics raise an objection to these points several times. the basic logic behind their arguments is this:

  1. A being with free will, given two options A and B, can freely choose between A and B.
  2. God is omniscient (all-knowing).
  3. God knows I will choose A.
  4. God cannot be wrong, since an omniscient being cannot have false knowledge.
  5. From 3 and 4, I will choose A and cannot choose B.
  6. From 1 and 5, omniscience and free will cannot co-exist.

I have read many counter-arguments from apologetics sites, but they were either too technical (I couldn’t understand them), or not satisfying. so, I was wondering what would your input be on this issue?

Thank you,

Justin

Ever heard that one? I actually had that one posed to me by a guy I used to work with who had a Ph.D in computer science from Northwestern. So this is an objection you may actually here.

Here’s Lenny Eposito’s answer:

Hi Justin,

Thanks for writing. This is a great question as it shows how even those who appeal to logic can have biases that blind them. Let’s examine this argument and see if it follows logically.

Premises 1 and 2 in your outline above are the main premises to the argument and are not disputed. The Christian worldview argues that every human being is a free moral agent and is capable of making choices simply by exercising their will, not under compulsion or because of instinct. Also, it is a long held doctrine of Christianity that God is all-knowing. The Bible says that God knows “the end from the beginning (Isaiah 46:10).” For omniscience to be truly knowledgeable it must be correct knowledge, so premise number 4 is also granted.

However, point number 5 is where the logic falters. Those who argue in this manner make the mistake of thinking that because God possesses knowledge about a specific matter, then he has influenced it. That does not follow at all. Just because God can foresee which choice you will make, it does not mean you couldn’t still freely choose the other option.

Let me give you an example. I have a five year old son. If I were to leave a chocolate chip cookie on the table about a hour before dinner time and my son was to walk by and see it, I know that he would pick up the cookie and eat it. I did not force him to make that decision. In fact, I don’t even have to be in the room at all. I think I know my son well enough, though, to tell you that if I come back into the kitchen the cookie will be gone. His act was made completely free of my influence, but I knew what his actions would be.

In examining the argument, the assumption is made in premise 3 that because God knows I will choose A somehow denies me the choice of B. That is the premise that Christianity rejects. Omniscience and free will are not incompatible and it is a non-sequitor to claim otherwise.

Thank you Justin for this interesting question. I pray that you will continue to defend the gospel of our Lord and may He continue to bless you as you seek to grow in Him.

That’s a great answer and should work in ordinary conversations.

More technical

J.W. Wartick maps out the arguments more fully with symbolic logic here on his Always Have A Reason blog. But I’ll just excerpt the gist of it.

Excerpt:

It is necessarily true that if God knows x will happen, then x will happen. But then if one takes these terms, God knowing x will happen only means that x will happen, not that x will happen necessarily. Certainly, God’s foreknowledge of an event means that that event will happen, but it does not mean that the event could not have happened otherwise. If an event happens necessarily, that means the event could not have happened otherwise, but God’s foreknowledge of an event doesn’t somehow transfer necessity to the event, it only means that the event will happen. It could have been otherwise, in which case, God’s knowledge would have been different.

[…]Perhaps I could take an example. Let’s say that I’m going to go to classes tomorrow (and I do hope I will, I don’t like missing classes!). God knows in advance that I’m going to go to classes tomorrow. His knowledge of this event means that it will happen, but it doesn’t mean that I couldn’t choose to stay in and sleep for a while, or play my new copy of Final Fantasy XIII, or do something more useless with my time. If I chose to, say, play Final Fantasy XIII (a strong temptation!), then God simply would have known that I would play FFXIII. His knowledge does not determine the outcome, His knowledge is simply of the outcome.

If we choose A, God would foreknow A. If we choose B, God would foreknow B. His foreknowledge of our choices is contingent on our making free choices.
