William Lane Craig asks: should Christians embrace postmodernism?

3 Comments

Here’s a short clip:

Dr. Craig thinks that Christianity does a lot better when it is commended to others using logic and evidence. He thinks that postmodernism undermines logic and evidence.

Sean McDowell has more on what this means for Christians:

In Postmodern Youth Ministry, for example, Tony Jones argues that postmodernity is the most important culture shift of the past 500 years, upending our theology, philosophy, epistemology (how we know things), and church practice. It is an “earthquake that has changed the landscape of academia and is currently rocking Western culture.” (p. 11). Thus, to be relevant in ministry today, according to Jones and other postmodernists, we must shed our modern tendencies and embrace the postmodern shift.

For the longest time I simply accepted that we inhabit a postmodern world and that we must completely transform our approach to ministry to be effective today. But that all changed when I had the opportunity of hearing philosopher William Lane Craig speak at an apologetics conference not too long ago. “This sort of [postmodern] thinking,” says Craig, “is guilty of a disastrous misdiagnosis of contemporary culture.” (“God is Not Dead Yet,” Christianity Today, July 2008, p. 26). He argues that the idea that we live in a postmodern world is a myth. This may strike you as awfully bold. How can he make such a claim?

For one thing, says Craig, postmodernism is unlivable and contradictory: “Nobody is a postmodernist when it comes to reading the labels on a medicine bottle versus a box of rat poison. If you’ve got a headache, you’d better believe that texts have objective meaning!” (Reasonable Faith, 2008, p. 18) Craig speaks to tens of thousands of (mostly non-Christian) college students around the world every year and his conclusion is that we live in a cultural milieu that is deeply modernist. Reason, logic, and evidence are as important today as ever (although he’s careful not to overstate their importance, too).

Postmodernism and Apologetics

But this is not all Craig has to say! In the introduction to Reasonable Faith, Craig provocatively claims, “Indeed, I think that getting people to believe that we live in a postmodern culture is one of the craftiest deceptions that Satan has yet devised” (p. 18). Accordingly, we ought to stop emphasizing argumentation and apologetics and just share our narrative. Craig develops this idea further:

And so Satan deceives us into voluntarily laying aside our best weapons of logic and evidence, thereby ensuring unawares modernism’s triumph over us. If we adopt this suicidal course of action, the consequences for the church in the next generation will be catastrophic. Christianity will be reduced to but another voice in a cacophony of competing voices, each sharing its own narrative and none commending itself as the objective truth about reality, while scientific naturalism shapes our culture’s view of how the world really is (p. 18-19).

In a personal email, Craig relayed to me that he believes postmodernism is largely being propagated in our church by misguided youth pastors. While he meant the comment more to elicit a smile than to be taken as a stab in the back, I can’t help but wonder if he is right.

If our culture were so profoundly postmodernist, why have the “New Atheists,” as Wired magazine dubbed them, been so influential? Popular writers such as Christopher Hitchens, Sam Harris, and Richard Dawkins have recently written bestselling books attacking the scientific, historic, and philosophical credibility of religion in general and Christianity in particular. Their writings have wreaked havoc on many unprepared Christians. If our culture were postmodern their challenges should have fallen on deaf ears.

This is my experience as well. When I was an undergraduate student, I attended IVCF and the woman running it (Jill) was a feminist who pushed postmodernism and feminism hard. Every week brought another testimony emphasizing love and forgiveness while minimizing or denying theology, science, history and logic. She turned down all the efforts of the men to bring in professors to speak about the cosmological argument or the resurrection, etc.. It was testimonies and prayer walks and praise hymns every week. When I questioned the people she chose to give their testimonies (mostly women), I found that none had any reasons for thinking that what they were talking about really was true. As a consequence of that, they were soft on doctrine – regularly throwing out Bible verses that did “resonate” with their “intuitions”. The same thing happened to me again with Campus Crusade as a graduate student. Personal testimonies of changed lives, divorced from any search for truth, every week.

One girl in particular that I knew at that time named Kerry was fond of bashing the laws of logic and the use of evidence. When I questioned her about it, she cited the influence of a charismatic youth pastor named Drew. A little more probing revealed that she denied the reality of Hell, and was a universalist. She eventually married a friend of mine and to this day has never read a single book on apologetics all the way through. Her beliefs are very much focused on the here and now, making friends and feeling good about herself. She never shook the habit of dismissing any argument, no matter how well-supported, that contradicted her intuitions.

Advice for Christians who discuss their faith with atheists… from an atheist

10 Comments

I spotted this post by Jeffery Jay Lowder on The Secular Outpost, and I think it’s good advice.

There are times where two people speak the same language, use the same words, and mean very different things by the same words. In conversations between Christians and atheists, “faith” is one such word. For many atheists, the word “faith” means, by default, belief without evidence or even belief against the evidence. In contrast, I doubt many Christians would accept that definition. For example, according to the NIV translation, Hebrews 11:1 states, “Now faith is confidence in what we hope for and assurance about what we do not see.”

Victor Reppert, at Dangerous Idea, writes this about the word “faith.”

Every time you use the word “faith” in a discussion with an atheist, they are going to declare victory. They will presume that you are believing for no reason, and that you are are admitting that the evidence is against you.

I think he is probably right. If Christians want to dialogue with atheists, I think Christians would be well served to speak the ‘language’ of atheists. The word “faith” simply has too much baggage associated with it; inserting that word into the conversation is likely to become a distraction from whatever point the Christian was probably trying to make. So if you’re a Christian talking with atheists, my advice is to temporarily delete the word “faith” from your vocabulary. Find some other way to make your point.

A better word to use is “trust”, and here’s Christian apologist Greg Koukl of Stand to Reason to make the same point:

Christian apologist Jonathan Morrow had a similar post on Think Christianly. (Mark well the part he put in bold)

Excerpt:

In today’s post I want to share a conversation I had with some of the sharp young men during lunch. It had to do with how we talk about Christianity with our friends, family, and coworkers. Most of the time, well meaning Christians talk about Christianity in the context of religion…not reality. Is that a problem? Yes, and here’s why. Religion is understood as a personal and private feeling that is not accessible by everyone else. You can’t question, challenge, or investigate it; you must simply be tolerant of it (and by tolerant, I am using the modern misunderstanding of tolerance which believes that all religious views are equally valid simply because a person sincerely believes them). That’s why having a conversation about Christianity as a religion is a dead end. It’s a non-starter.

That’s why I encouraged these students to talk about Christianity in the context of reality where terms like truth, knowledge, reason, and evidence apply. Any claim about reality is either true or false (it can’t be both). If Christianity is not the kind of thing that can be true or false…the battle has already been lost and the Gospel cannot be seriously considered. We need to talk about Christianity in the same way we talk about having a prescription filled at the pharmacy or receiving instruction from a Doctor.

In today’s society, religion is a fuzzy (i.e., socially constructed or psychologically projected) category that makes little difference in everyday life. But if Christianity is true, then it speaks to ALL of life. It makes a comprehensive claim on reality. Jesus didn’t intend to merely address two hours of our week. As Christians we need to have more conversations about reality and less about religion.

I’ve even written a post about the concept of faith that is presented in the Bible and the word faith has nothing to do with blind belief in the Bible – it’s always based on evidence, so that people can know for certain what the truth is. I highly recommend it for anyone who disagrees with Jeffery,Greg or Jonathan. When you’re talking about Christianity, you’re talking about what you know. You’re talking about the way the world is, for everyone. When you talk about your belief in God, you should say “trust”. You should not say “faith”.

Positive arguments for Christian theism

Cornelius Van Til and presuppositional apologetics

39 Comments

Here’s J.W. Wartick’s take from Always Have a Reason blog.

Excerpt:

Cornelius Van Til pioneered the field of “presuppositional apologetics” primarily through his works Christian Apologetics and The Defense of the Faith. His arguments are easily misunderstood as question begging or viciously circular. Herein, I have presented a brief outline and analysis which reveals that while the presuppositional approach may indeed have some logical faults, the overall system has a certain power to it and can be integrated into a total-apologetic system.

[…]The key to understand here is that Van Til does not accept that there is a neutral reason “out there” by which Christians and non-Christians can arbitrate the truth of Christianity; his point is that there is no neutral ground and that one’s presuppositions will determine one’s end point. Again, he writes, “this [apologetic method] implies a refusal to grant that any area or aspect of reality, any fact or any law of nature or of history, can be correctly interpreted except it be seen in the light of the main doctrines of Christianity” (Christian Apologetics, 124).

However, Van Til takes it even further and argues that one must presuppose the truth of Christianity in order to make sense of reality: ” What is the content of this presupposition, then? It is this: “I take what the Bible says about God and his relation to the universe as unquestionably true on its own authority” (The Defense of the Faith, 253); again, “The Bible is thought of as authoritative on everything of which it speaks. Moreover, it speaks of everything” (Christian Apologetics, 19). Thus, Van Til’s apologetic does not make Christianity the conclusion of an argument; rather, Christianity is the starting presupposition.

The presuppositional approach here cannot be stressed enough. For Van Til, one simply cannot grant to the non-Christian any epistemic point. “We cannot avoid coming to a clear-cut decision with respect to the question as to whose knowledge, man’s or God’s, shall be made the standard of the other. …[O]ne must be determinative and the other subordinate” (The Defense of the Faith 62-63).

What place is had for evidences in Van Til? At some points, he seems to be very skeptical of the use of Christian evidences. In particular, the fact that he argues there is no neutral evaluation grounds between the Christian and non-Christian seems to imply that  there can be no real evaluation of such arguments apart from Christianity. One of Van Til’s most famous illustrations of the use of evidences can be found in The Defense of the Faith pages 332 and following. He uses three persons, Mr. Black (non-Christian), Mr. Grey (Christian non-presuppositionalist), and Mr. White (presuppositional/reformed apologist):

Mr. Grey… says that, of course, the “rational man” has a perfect right to test the credibility of Scripture by logic… by experience… [Mr. Grey then takes Mr. Black a number of places to show him various theistic evidences. Mr. Black responds:] “you first use intellectual argument upon principles that presuppose the justice of my unbelieving position. Then when it it is pointed out to you that such is the case, you turn to witnessing [subjectively].

…At last it dawned upon Mr. White that first to admit that the principles of Mr. Black, the unbeliever, are right and then to seek to win him to the acceptance of the existence of God the Creator… is like first admitting that the United States had historically been a province of the Soviet Union but ought at the same time to be recognized as an independent and all-controlling power… If one reasons for the existence of God and for the truth of Christianity on the assumptions that Mr. Black’s principles of explanation are valid, then one must witness on the same assumption [which makes witnessing wholly subjective.] (p. 332-339)

It can be seen here that even evidences for Van Til must be based within a presupposition. There is no way to look at evidences in the abstract. One can either offer them within the presuppositions of Christianity or outside of Christianity. For Van Til, once one has agreed to offer evidences outside of Christianity, one has granted the presuppositions of the non-believer, and therefore is doomed to fail.

This would include using arguments like the cosmological argument, the fine-tuning argument, arguments from miracles, etc. – including the resurrection. That seems to be Van Til’s view. No evidence allowed – you have to presuppose Christianity is true in order to make sense of the world.

Now, I think we need to make a distinction between using questioning the pre-suppositions of our opponents, as with William Lane’s Craig’s moral argument, Plantinga’s epistemological argument for reason and Menuge’s ontological argument for reason. There are arguments for theism that question the pre-suppositions of an atheist. Certainly, non-theists cannot ground things like morality, free will, consciousness and rationality on atheism. But that’s not what Van Til is saying. He says that an atheist cannot be swayed by evidence unless he first becomes a Christian. I.e. – he is saying that atheist Anthony Flew is lying when he says that evidence caused him to turn to believe in God. On Van Til’s view, that’s impossible.

My view of presuppositional apologetics is that is as a system, it is circular reasoning. It assumes Christianity in order to prove Christianity. But there is an even worse problem with it. It’s not a Biblical way of doing apologetics. It’s man’s way of doing apologetics, not God’s. I think that the best way to understand Van Til’s apologetics is by saying that it really just a sermon disguised as apologetics. The problem is that Van Til’s sermon has no basis in the Bible. Wherever he is getting his view from, it’s not from the Bible. When I look the Bible, I don’t see any Biblical support for the view that pre-suppositional apologetics is the only approved way of defending the faith. Instead, the standard method seems to be evidentialism.

In Romans 1, Paul writes that people can learn about God’s existence from the natural world.

Romans 1:18-23:

18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness,

19since what may be known about God is plain to them, because God has made it plain to them.

20For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

22Although they claimed to be wise, they became fools

23and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

And in Acts, Peter appeals to eyewitness testimony for the resurrection, and Jesus’ miracles.

Acts 2:22-24, and 36:

22“Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know.

23This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.

24But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

And finally from the same chapter:

36“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ.”

Professor Clay Jones of Biola University makes the case that the use of evidence when preaching the gospel was standard operating procedure in the early church. (H/T Apologetics 315)

Intro:

In 1993 I started working for Simon Greenleaf University (now Trinity Law School) which offered an M.A. in Christian apologetics (Craig Hazen was the director). Much of my job was to promote the school and although I had studied Christian apologetics since my sophomore year in high school, I decided I needed to see whether an apologetic witness had strong Biblical precedence.

It does.

As I poured through the Scripture I found that Jesus and the apostles preached the resurrection of Christ as the sign of the truth of Christianity.

What follows are some of the passages which support the resurrection witness.

Here is my favorite verse from his massive list list of verses in favor of the evidential approach to Christian apologetics:

Mat. 12:39-40: A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah. For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.

Jesus is saying that the resurrection was deliberately given as a sign to unbelievers to convince them. (“The Sign of Jonah” = the resurrection)

So, I see that God uses nature and miracles to persuade, which can be assessed using scientific and historical methods. Can anyone find me a clear statement in the Bible that states that only pre-suppositional arguments should be used? I could be wrong, and I am willing to be proven wrong. I think we should use the Biblical method of apologetics, not the fallen man’s method of apologetics.
