Alister McGrath: Does It Matter if Christianity Is Rational?

Apologetics isn’t just the church reaching out to people beyond the faith and helping them to understand what it is and the difference it makes. It’s also about speaking to the choir, people inside the church, and reassuring them that their faith makes sense, reassuring them that they’ll be able to talk to their friends about their faith. So in many ways, I want to emphasize the real importance of having traveling companions. That is to say, other Christians who can help you think things through, who can encourage you, who can, in effect, travel with you through life, while at the same time speaking to those who are outside the faith, who are looking in and wondering, ‘Hey, what’s all this about?’ There’s something very exciting for them to discover, and trying to help them see what this might be and begin to move on in their journey of exploration and discovery.

Episode Overview

Can We Speak About Jesus’s Transforming Power Without Reducing It To a Consumer Product?

You can believe Christianity is true and still wonder what difference it makes. Theologian and former atheist Alister McGrath joins Curtis Chang to discuss Rethinking Christianity and why conversations about faith need to address meaning, purpose, and hope alongside rational belief. They explore the danger of reducing Christianity to self-help, the limits of intellectual answers to suffering, and how Jesus’ suffering speaks to people in their darkest moments. Curtis also shares his experience of anxiety and depression as they consider how truth, lived experience, and Christian friendship can sustain faith.

Scripture from the Episode

Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock. And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand. And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.
Matthew 7:24–27
Now when Jesus learned that the Pharisees had heard that Jesus was making and baptizing more disciples than John (although Jesus himself did not baptize, but only his disciples), he left Judea and departed again for Galilee. And he had to pass through Samaria. So he came to a town of Samaria called Sychar, near the field that Jacob had given to his son Joseph. Jacob’s well was there; so Jesus, wearied as he was from his journey, was sitting beside the well. It was about the sixth hour. A woman from Samaria came to draw water. Jesus said to her, “Give me a drink.” (For his disciples had gone away into the city to buy food.) The Samaritan woman said to him, “How is it that you, a Jew, ask for a drink from me, a woman of Samaria?” (For Jews have no dealings with Samaritans.) Jesus answered her, “If you knew the gift of God, and who it is that is saying to you, ‘Give me a drink,’ you would have asked him, and he would have given you living water.” The woman said to him, “Sir, you have nothing to draw water with, and the well is deep. Where do you get that living water? Are you greater than our father Jacob? He gave us the well and drank from it himself, as did his sons and his livestock.” Jesus said to her, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” The woman said to him, “Sir, give me this water, so that I will not be thirsty or have to come here to draw water.” Jesus said to her, “Go, call your husband, and come here.” The woman answered him, “I have no husband.” Jesus said to her, “You are right in saying, ‘I have no husband’; for you have had five husbands, and the one you now have is not your husband. What you have said is true.” The woman said to him, “Sir, I perceive that you are a prophet. Our fathers worshiped on this mountain, but you say that in Jerusalem is the place where people ought to worship.” Jesus said to her, “Woman, believe me, the hour is coming when neither on this mountain nor in Jerusalem will you worship the Father. You worship what you do not know; we worship what we know, for salvation is from the Jews. But the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship him. God is spirit, and those who worship him must worship in spirit and truth.” The woman said to him, “I know that Messiah is coming (he who is called Christ). When he comes, he will tell us all things.” Jesus said to her, “I who speak to you am he.” Just then his disciples came back. They marveled that he was talking with a woman, but no one said, “What do you seek?” or, “Why are you talking with her?” So the woman left her water jar and went away into town and said to the people, “Come, see a man who told me all that I ever did. Can this be the Christ?” They went out of the town and were coming to him. Meanwhile the disciples were urging him, saying, “Rabbi, eat.” But he said to them, “I have food to eat that you do not know about.” So the disciples said to one another, “Has anyone brought him something to eat?” Jesus said to them, “My food is to do the will of him who sent me and to accomplish his work. Do you not say, ‘There are yet four months, then comes the harvest’? Look, I tell you, lift up your eyes, and see that the fields are white for harvest. Already the one who reaps is receiving wages and gathering fruit for eternal life, so that sower and reaper may rejoice together. For here the saying holds true, ‘One sows and another reaps.’ I sent you to reap that for which you did not labor. Others have labored, and you have entered into their labor.” Many Samaritans from that town believed in him because of the woman’s testimony, “He told me all that I ever did.” So when the Samaritans came to him, they asked him to stay with them, and he stayed there two days. And many more believed because of his word. They said to the woman, “It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is indeed the Savior of the world.”
John 4:1–42
The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly.
John 10:10
Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me.
Psalm 23:4
