Francis Schaeffer, the Swiss-dwelling American theologian, philosopher, and founder of L’Abri Fellowship, was not merely a man of letters. He was a man of compassion and urgency—urgency for truth, urgency for people, and urgency for the cultural moment. Schaeffer’s apologetic method was not a sterile intellectual exercise, nor was it a show of superior reasoning skills for the sake of argument. It was an act of love: a method to awaken souls dulled by the illusions of modern and postmodern thought.
At the core of Schaeffer’s method was a two-fold movement—tearing down the roof and building a foundation. He sought to show people the inevitable despair and contradiction within their non-Christian worldviews by gently guiding them to the logical end of their beliefs. Once they stood at the brink of existential collapse, Schaeffer would present the Christian worldview—not merely as an option, but as the coherent, satisfying, truth-rooted explanation of reality.
Step One: Taking Off the Roof
Schaeffer likened many modern and postmodern worldviews to a “roof” people lived under to protect themselves from the storm of meaninglessness. These “roofs” were constructed from cultural clichés, borrowed ethics, half-remembered religious sentiments, or fashionable academic theories. Most adherents had never truly examined the foundations of their beliefs. They borrowed moral language from Christianity while denying its metaphysical grounding, or they prized reason and science while affirming materialism, which undercuts both.
Schaeffer’s goal in “taking off the roof” was to lovingly expose the internal contradictions of a worldview—to force the thinker to live consistently within their own assumptions and see where it leads. If the worldview could not explain the dignity of man, the existence of beauty, the reality of moral absolutes, or the possibility of knowledge, then it was bankrupt.
Step Two: Building on the Rock
Once a person recognized the absurdity or unlivability of their worldview, Schaeffer offered Christianity—not as religious sentiment, but as a comprehensive worldview grounded in objective truth. Christianity affirms that the universe has a rational order because it was created by a rational God. It explains the dignity of man because humans are made in the image of God. It accounts for moral absolutes because they are grounded in the character of a holy Creator. And it validates our longing for meaning, beauty, and justice because we live in a fallen world awaiting redemption.
Schaeffer’s goal was not conversion by intellectual defeat but conversion through illumination—helping someone see reality clearly, sometimes for the first time.
A Fictitious Dialogue: Francis Schaeffer Meets the Postmodern Mind
Setting: A simple room in the Swiss Alps, filled with books, warm light, and an atmosphere of hospitality. Francis Schaeffer sits across from Eli, a confident and thoughtful college student studying philosophy at a prominent American university. Eli is intelligent, inquisitive, and steeped in postmodern thought.
Eli: Dr. Schaeffer, I appreciate your hospitality. Honestly, I’m intrigued by your reputation. But I should tell you—I’m a postmodernist. I don’t believe in absolute truth, and I think each person constructs their own reality. We live in a pluralistic world, and that’s a good thing.
Schaeffer: Eli, I’m glad you’re here. You’re welcome, just as you are. Let’s talk about your beliefs. When you say you don’t believe in absolute truth, is that an absolute truth?
Eli (smirking): Touché. I’ve heard that one before. But seriously, truth is subjective—it’s shaped by our culture, our upbringing, even our biology. What’s true for you isn’t necessarily true for me.
Schaeffer: I see. But may I gently press you on that? Suppose someone tells you that slavery is good and human trafficking is just their cultural norm. Would you say, “That’s true for them?”
Eli (frowning): No, of course not. That’s immoral.
Schaeffer: But by what standard, Eli? If morality is relative, and truth is subjective, what gives you the right to condemn someone else’s culture or moral code?
Eli: Well… we have social contracts, and we evolve better systems of justice over time.
Schaeffer: Then justice is a product of power, not a transcendent standard. If history had gone differently, and Nazi Germany had won the war and written the textbooks, would their definition of morality be just as valid?
Eli (quietly): I’d like to think not.
Schaeffer: You know it wouldn’t be. Your conscience tells you that human beings have value, that some actions are genuinely wrong—regardless of who wins the war. But your worldview can’t explain why. You’re borrowing moral capital from a Christian framework while denying the Source.
Eli: That’s a strong claim.
Schaeffer: And a loving one. I believe you were made in the image of God. That’s why you instinctively believe in justice, beauty, love, and truth. But your worldview says those things are illusions—social constructs or chemical reactions in your brain. Doesn’t that leave you in despair?
Eli (pauses): Sometimes, yeah. I’ve had moments—late at night—when I wonder if anything really matters. I mean, we’re all just stardust, right?
Schaeffer: That’s the roof coming off. You’re seeing your worldview for what it really is. If we are cosmic accidents in a purposeless universe, then love, morality, and meaning are illusions. But you don’t live that way. You love your friends, you care about justice, you find beauty in music and literature. You live as if life matters.
Eli: So what are you saying? That Christianity explains all this?
Schaeffer: I am. Christianity says you were created by a personal, infinite God. That He made you for relationship with Him. That He gave you dignity, and that the very moral structure of the universe flows from His character. And though this world is broken by sin, God stepped into history in the person of Jesus Christ to redeem it. The longing you feel for meaning, truth, and love—that’s a signpost. It’s pointing you home.
Eli: But what about science, reason, and all that? Doesn’t religion ask me to abandon those?
Schaeffer: No. Christianity gave birth to modern science because it affirms that the world is orderly and knowable. Christianity doesn’t destroy reason—it redeems it. You’re not asked to abandon your mind, but to use it rightly—to see the world as it is, not as fashionable ideology says it is.
Eli (visibly moved): I’ve never heard it put that way. I guess… I didn’t realize how contradictory my views were. But what now?
Schaeffer (gently): Now you must decide. You’ve glimpsed the logical end of your worldview—it leads to despair. But there’s a better way. Christ offers not only forgiveness, but coherence. He’s not just true for you—He’s the truth. Will you seek Him?
Eli: I think I will.
Conclusion: A Roof Torn Off, A Life Rebuilt
Francis Schaeffer’s genius was not in wielding logic like a sword, but in loving people enough to tell them the truth. He understood the times, but more importantly, he understood the human soul. In a world drunk on relativism and lost in a sea of subjectivity, Schaeffer’s apologetic method remains as necessary as ever. It challenges the intellectual pretenses of modern and postmodern man and invites them to step into the light of God’s truth—where dignity, reason, morality, and love are not illusions, but reflections of the One in whose image we are made.
