Apologetics in the gospel of John

Bible study that hits the spot

John is my favorite gospel, because the thing reads like a well constructed essay. The author makes a number of claims about who Jesus was, and supplies evidence for each claim. There is nothing extraneous to John’s thesis, the whole thing that he wrote is designed to make a case.

My friend Eric Chabot wrote a post on his blog on the use of apologetics in the gospel of John. (H/T J. Warner Wallace tweet)

Here is his thesis:

In this post, I will highlight some of the different ways John utilizes apologetics in his testimony of who Jesus is.

He talks about how God has his messengers use evidence:

3.Signs and Miracles

While actions by other prophets such as Ezekiel and Jeremiah etc. show some significant parallels to Jesus, Jesus is closer to the actions of the Jewish sign prophetssuch as Moses. “Signs” have a specific apologetic function in that they are used to provide evidence for people to believe the message of God through a prophet of God. Hence, the signs Moses does proves he is truly sent from God.  Moses had struggled with his prophetic call when he said “ But they will not believe me or listen to my voice, for they will say ‘The Lord did not appear to you.’ (Exod. 4:1). God assures Moses that  the “signs”  will confirm his call:

God says, “I will be with you. And this will be אוֹת “the sign”  to you that it is I who have sent you” (Exod. 3:12).

“If they will not believe you,” God said, “or listen to the first sign, they may believe the latter sign. If they will not believe even these two signs or listen to your voice, you shall take some water from the Nile and pour it on the dry ground, and the water that you shall take from the Nile will become blood on the dry ground.” (Exod 4: 8-9).

We see the signs are used to help people believe.

Moses “performed the “signs” before the people, and they believed; … they bowed down and worshiped” (Exod. 4:30–31)

So what did Jesus do?

“Works” are directly related to the miracles of Jesus (Jn. 5:20; 36;10:25; 32-28; 14:10-12; 15:24) and is synonymous with “signs.” Interestingly enough, when Jesus speaks of miracles and he calls them “works” he doesn’t refer to  Exod. 4:1-9, but to Num. 16:28, “Hereby you shall know that the LORD has sent me to do all these works, and that it has not been of my own accord.” For example:

Jesus answered them, “I told you, and you do not believe. The works that I do in my Father’s name bear witness about me” (John 10:25).

If I am not doing the works of my Father, then do not believe me;  but if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me and I am in the Father.” (John 10:37-38).

But the testimony that I have is greater than that of John. For the works that the Father has given me to accomplish, the very works that I am doing, bear witness about me that the Father has sent me (John 5: 36)

“Sign”(sēmeion) is used seventy-seven times (forty-eight times in the Gospels). As far as the “signs’ Jesus does,  29:18-19; 35:5-6; 42:18; 61:1). In John’s Gospel, Jesus performs three “signs,” at the beginning of his ministry; the water turned into wine at Cana at Galilee (2:1-12), the healing of the son of the royal official at Capernaum (4:46-64), and catching of the fish in the sea of Galilee (21:1-14). The link between the first two signs in Jn 2:12 while the link between the last two are seen in Jn 7:1, 3-4, 6, 9. Jesus follows the pattern of Moses in that he reveals himself as the new Moses because Moses also had to perform three “signs” so that he could be recognized by his brothers as truly being sent by God (Exod 4: 1-9). In the exchange between Nicodemus said to Jesus, Nicodemus said, We know you are a teacher who has come from God. For no one could perform the miraculous signs you are doing if God were not with him” (John 3:2)

Also, regarding miracles, in some cases the miracle is a witness against those who reject this evidence. John grieved: “Even after Jesus had done all these miraculous signs in their presence, they still would not believe in him” (John 12:37). One result, though not the purpose, of miracles is condemnation of the unbeliever (cf. John 12:31, 37).

The gospel of John is so good. Or is it that Jesus is just so good to not be like some idiot who just says things that no one can test? That would be stupid and annoying – it’s much better for Jesus to do these signs so that people could believe him about his identity and purpose. Do you like Jesus? I like Jesus.

I read John a long time ago, when I was about 10 or 11 years old.I can’t remember what I thought of it, but it probably had a very good effect on me as far as making me think that Christianity was something that I ought to look into. The gospel of John is that good. Philippians is still my favorite book of the Bible (because it’s practical, duh), but John is the best introduction. It’s the first thing a non-Christian should read to at least understand what Christianity is all about. Everybody should at least know that!

William Lane Craig debates Austin Dacey: Does God Exist?

Two tough rams butt heads, and may the best ram win!
Two tough rams butt heads, and may the best ram win!

Here is the video and summary of a debate between Christian theist William Lane Craig and Austin Dacey at Purdue University in 2004 about the existence of God.

The debaters:

The video: (2 hours)

The video shows the speakers and powerpoint slides of their arguments. Austin Dacey is one of the top atheist debaters, and I would put him second to Peter Millican alone, with Walter Sinnott-Armstrong in third place. This is the debate to show people who are new to apologetics. The debate with Peter Millican is better for advanced students, and that’s no surprise since he teaches at Oxford University and is familiar with all of Dr. Craig’s work. The Craig-Dacey debate is the one that I give to my co-workers.

By the way, you can get the DVDs and CDs for the first Craig-Dacey debate and the second Craig-Dacey debate and the second Craig-Sinnott-Armstrong debate. The Peter Millican debate is not available on DVD, but the link above (Peter Millican) has the video and my summary.

Dr. Dacey’s 5 arguments below are all good arguments that you find in the academic literature. He is also an effective and engaging speaker, This is a great debate to watch!

SUMMARY of the opening speeches:

Dr. Craig’s opening statement:

Dr. Craig will present six reasons why God exists:

  1. (Contingency argument) God is the best explanation of why something exists rather than nothing
  2. (Cosmological argument)  God’s existence is implied by the origin of the universe
  3. (Fine-tuning argument) The fine-tuning of the universe for intelligent life points to a designer of the cosmos
  4. (Moral argument) God is the best explanation for the existence of objective moral values and objective moral duties
  5. (Miracles argument) The historical facts surrounding the life, death and resurrection of Jesus
  6. (Religious experience) God’s existence is directly knowable even apart from arguments

Dr. Dacey’s opening argument:

There are two ways to disprove God’s existence, by showing that the concept of God is self-contradictory, or by showing that certain facts about ourselves and the world are incompatible with what we would expect to be true if God did exist. Dr. Dacey will focus on the second kind of argument.

  1. The hiddenness of God
  2. The success of science in explaining nature without needing a supernatural agency
  3. The dependence of mind on physical processes in the brain
  4. Naturalistic evolution
  5. The existence of gratuitous / pointless evil and suffering

One final point:

One thing that I have to point out is that Dr. Dacey quotes Brian Greene during the debate to counter Dr. Craig’s cosmological argument. Dr. Craig could not respond because he can’t see the context of the quote. However, Dr. Craig had a rematch with Dr. Dacey where was able to read the context of the quote and defuse Dr. Dacey’s objection. This is what he wrote in his August 2005 newsletter after the re-match:

The following week, I was off an another three-day trip, this time to California State University at Fresno. As part of a week of campus outreach the Veritas Forum scheduled a debate on the existence of God between me and Austin Dacey, whom I had debated last spring at Purdue University. In preparation for the rematch I adopted two strategies: (1) Since Dacey had come to the Purdue debate with prepared speeches, I decided to throw him for a loop by offering a different set of arguments for God, so that his canned objections wouldn’t apply. I chose to focus on the cosmological argument, giving four separate arguments for the beginning of the universe, and on the evidence for Jesus’ resurrection. (2) I reviewed our previous debate carefully, preparing critiques of his five atheistic arguments. In the process I found that he had seriously misunderstood or misrepresented a statement by a scientist on the Big Bang; so I brought along the book itself in case Dacey quoted this source again. I figured he might change his arguments just as I was doing; but I wanted to be ready in case he used his old arguments again.

[…]The auditorium was packed that night for the debate, and I later learned that there were overflow rooms, too. To my surprise Dr. Dacey gave the very same case he had presented at Purdue; so he really got clobbered on those arguments. Because he wasn’t prepared for my new arguments, he didn’t even respond to two of my arguments for the beginning of the universe, though he did a credible job responding to the others. I was pleased when he attacked the Big Bang by quoting the same scientist as before, because I then held up the book, specified the page number, and proceeded to quote the context to show what the scientist really meant.

Dr. Craig is always prepared!

How to falsify a religion using scientific or historical evidence

Will the universe expand forever, or will it collapse and bounce?
Will the universe expand forever, or will it collapse and bounce?

What I often see among atheists is this tendency to set up expectations of how God would have acted and then complain that he doesn’t met those expectations. I don’t think that this is a good way to argue against a religion, because it’s subjective. God isn’t obligated to comport with atheist expectations. A much better way of evaluating religions is to test the claims each makes against evidence.

So in this post, I wanted to show how a reasonable person can evaluate and reject different worldviews using evidence.

Falsifying a religion using science

Consider this argument:

  1. Hindu cosmology teaches that the universe cycles between creation and destruction, through infinite time.
  2. The closest cosmological model conforming to Hindu Scriptures is the eternally “oscillating” model of the universe.
  3. The “oscillating” model requires that the universe exist eternally into the past.
  4. But the evidence today shows the the universe, and time itself, had a beginning at the big bang.
  5. The “oscillating” model requires that the expansion of the universe reverse into a collapse, (= crunch).
  6. In 1998, the discovery of the year was that the universe would expand forever. There will be no crunch.
  7. Therefore, the oscillating model is disconfirmed by observations.
  8. The oscillating model also faces theoretical problems with the “bounce” mechanism.

Notice how the oscillating model is falsified by mathematics and experimental evidence. Remarkable, when you remember how the public schools would play Carl Sagan videos which promoted this no-Creator model of the universe.

The absolute origin of the universe out of nothing is also incompatible with atheism, Buddhism, Mormonism, etc. because they also require an eternally existing universe.

Atheism in particular is incompatible with the universe “coming into being”, because that would be a supernatural cause – a cause that created the natural world. According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing.

Falsifying a religion using history

Consider this argument:

  1. To be a Muslim, you must believe that the Koran is without error.
  2. The Koran claims that Jesus did not die on a cross. (Qur’an, 4: 157-158)
  3. The crucifixion of Jesus is undisputed among non-Muslim historians, including atheist historians.
  4. Therefore, it is not rational for me to become a Muslim.

I’m going to support the premise that Jesus was crucified by citing historians from all backgrounds.

Consider some quotes from the (mostly) non-Christian scholars below:

“Jesus’ death as a consequence of crucifixion is indisputable.” Gert Lüdemann

“That he was crucified is as sure as anything historical can ever be.”  J.D. Crossan

“The passion of Jesus is part of history.” Geza Vermes

Jesus’ death by crucifixion is “historically certain”. Pinchas Lapide

“The single most solid fact about Jesus’ life is his death: he was executed by the Roman prefect Pilate, on or around Passover, in the manner Rome reserved particularly for political insurrectionists, namely, crucifixion.” Paula Fredriksen

“The support for the mode of his death, its agents, and perhaps its co-agents, is overwhelming: Jesus faced a trial before his death, was condemned, and was executed by crucifixion.” L.T. Johnson

“One of the most certain facts of history is that Jesus was crucified on orders of the Roman prefect of Judea, Ponitus Pilate.” Bart Ehrman

That’s 7 famous historians: 3 atheists, 3 Jews and 1 moderate Catholic. The atheists, Ludemann, Crossan and Ehrman, have all debated against the resurrection of Jesus with William Lane Craig. Johnson is the moderate Catholic, the rest are Jewish historians. The Koran was written in the 7th century. That is why no professional historian accepts the Koran as more authoritative than the many earlier Christian and non-Christian sources for the crucifixion story. Many of the sources for the crucifixion are dated to the 1st century. It’s not faith. It’s history.

I have seen debates with Muslim scholars, and I have never once heard them cite a non-Muslim historian to the effect that Jesus was not crucified. To my knowledge, there is no (non-Muslim) historian who denies the crucifixion of Jesus in his published work.

Can Christianity be falsified by science or history?

Yes. If you prove that the universe is eternal than would falsify the Bible’s claim that God created the universe out of nothing. That would be a scientific disproof. If you could find the body of Jesus still inside a tomb, that would falsify the Bible’s claim about a resurrection. That would be a historical disproof. The nice thing about Christianity is that we make lots of testable claims. When someone claims to be a Christian, it’s a good thing if they can show how they arrived at that conclusion. Being able to square God’s existence with science, and Jesus’ resurrection with history are two crucial steps to showing the reasonableness of Christianity.
