Given Jesus' remarkable claims—both in His words and actions—we face an unavoidable question: Who was He really? Many today want to honor Jesus as a great moral teacher while rejecting His claims to deity. But as C.S. Lewis famously argued, this option is not available. The nature of Jesus' claims forces us to a decision: Was He a deliberate deceiver, a sincere but deluded madman, or exactly who He claimed to be—the Lord of all?
The Trilemma
C.S. Lewis presented this argument in his classic work Mere Christianity:
Lewis's Trilemma
"I am trying here to prevent anyone saying the really foolish thing that people often say about Him: 'I'm ready to accept Jesus as a great moral teacher, but I don't accept His claim to be God.' That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic—on a level with the man who says he is a poached egg—or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God: or else a madman or something worse."
"You can shut Him up for a fool, you can spit at Him and kill Him as a demon; or you can fall at His feet and call Him Lord and God. But let us not come with any patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to."
The logic is straightforward: Jesus claimed to be God. This claim is either true or false. If false, Jesus either knew it was false (making Him a liar) or believed it was true when it wasn't (making Him a lunatic). If true, He is Lord. There is no fourth option—no "merely a good teacher" category that honors His teaching while dismissing His central claims.
Why "Good Teacher" Isn't an Option
Many people want to admire Jesus while avoiding the implications of His deity. They praise His ethical teaching, His compassion for the marginalized, His example of love and sacrifice. Surely, they suggest, we can appreciate these things without accepting supernatural claims?
But this approach fails for several reasons:
His Claims Are Central, Not Peripheral
Jesus' divine claims aren't incidental additions to His teaching that we can ignore while accepting the rest. They're woven throughout His ministry. Remove them, and there's nothing left:
His ethical teaching is grounded in His authority: "You have heard that it was said... but I say to you" (Matthew 5:21-22). He doesn't cite other authorities; He speaks as the authority.
His salvation comes through Himself: "I am the way, and the truth, and the life. No one comes to the Father except through me" (John 14:6). This isn't humble teaching; it's an exclusive claim to be the only path to God.
His call to discipleship is a call to follow Him: "Follow me" (Mark 1:17). Not "follow these principles" but "follow me personally."
To reject Jesus' divine claims while accepting His teaching is to accept a Jesus who never existed—a teacher who never made such claims. But the historical Jesus did make them, constantly and centrally.
Good Teachers Don't Make False Claims About Themselves
If Jesus' claims are false, He can't be a good teacher. Good teachers don't teach falsehoods, especially falsehoods of this magnitude. Claiming to be God when you're not is either deliberate deception or tragic delusion—neither is compatible with being a "great moral teacher."
The claim to deity isn't a minor mistake like getting a date wrong. It's a claim that, if false, involves the most extreme arrogance imaginable—placing oneself in the position of the Almighty. A person who falsely makes this claim is either morally corrupt (a liar) or mentally disturbed (a lunatic). Neither category allows for "great moral teacher."
His Contemporaries Didn't See a Middle Option
Those who encountered Jesus didn't have the luxury of viewing Him as "just a good teacher." They recognized that His claims demanded a response: worship or rejection. The religious leaders sought to kill Him for blasphemy; His disciples worshiped Him as Lord and God. No one said, "What wonderful ethics, but let's ignore the God stuff."
The "good teacher" option is a modern invention, created by those who want Jesus' moral authority without His moral demands. But it's not historically available. Jesus didn't leave that door open.
"For this reason the Jews were seeking all the more to kill him, because not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God."
— John 5:18 (ESV)
Option 1: Liar
If Jesus' claims were false and He knew they were false, He was a deliberate deceiver—a liar on a colossal scale.
What This Would Mean
Consider the implications: Jesus would have knowingly deceived His followers about the most important question in the universe. He would have claimed to be God, accepted worship, and promised eternal life—all while knowing it was false. He would have led countless people into idolatry (worshiping a mere human as God) and false hope (trusting in salvation He couldn't provide).
This deception would be monstrous. It's not a white lie to spare someone's feelings but the most consequential lie ever told—a lie about the nature of reality, the way of salvation, and the identity of God Himself.
Problems with the Liar Hypothesis
His character doesn't fit. Everything else we know about Jesus points to extraordinary moral integrity. His enemies couldn't convict Him of sin (John 8:46). His teaching on truthfulness is uncompromising. His life demonstrated sacrificial love, humble service, and unwavering commitment to truth. Does this sound like a calculating deceiver?
His death doesn't fit. Liars usually preserve their lives rather than die for their lies. Jesus had every opportunity to recant, to admit He wasn't God, to save Himself from torture and crucifixion. He didn't. He went to His death maintaining His claims. People die for what they believe to be true; they don't usually die for what they know to be false.
His impact doesn't fit. Jesus' teaching has inspired more genuine moral transformation than any other influence in history. Hospitals, universities, charitable organizations, human rights movements—all trace significant roots to Jesus' influence. How did a deliberate deceiver produce such fruit?
His teaching doesn't fit. Jesus' moral teaching is universally admired, even by non-Christians. But if He was a liar about the central matter of His identity, why should we trust His moral teaching? A person capable of such deception is capable of anything.
The Consistency Test
When evaluating whether someone is a liar, we look for consistency. Does their character fit the accusation? Are there other signs of deception?
With Jesus, we find remarkable consistency—but in the opposite direction. His character, teaching, and actions all point to integrity, not deception. To maintain the liar hypothesis, we must believe that Jesus was the most successful deceiver in history who somehow produced the most morally transformative movement in history while teaching the highest ethical standards in history. This strains credulity.
Option 2: Lunatic
If Jesus' claims were false but He sincerely believed them, He was deluded—a lunatic who genuinely thought He was God when He wasn't.
What This Would Mean
Believing yourself to be God when you're not is not a minor delusion. It's a fundamental break with reality of the most extreme kind. People who genuinely believe they are God typically exhibit other signs of mental illness—grandiosity, paranoia, incoherence, inability to function normally.
Problems with the Lunatic Hypothesis
His mental health doesn't fit. Jesus shows no signs of the psychological disturbance we would expect from someone with a messiah complex. He was emotionally stable, relationally healthy, and intellectually sharp. He engaged opponents in sophisticated debate, showed deep compassion without codependency, and handled pressure with remarkable composure.
His teaching doesn't fit. The depth, coherence, and practical wisdom of Jesus' teaching is inconsistent with mental illness. Paranoid schizophrenics don't produce the Sermon on the Mount. Delusional megalomaniacs don't teach "love your enemies" and "blessed are the meek." Jesus' teaching shows a mind operating at the highest level, not a mind disconnected from reality.
His insight into others doesn't fit. Jesus demonstrated penetrating insight into human nature—understanding people's thoughts, exposing hidden motives, speaking to the deepest needs of the human heart. This psychological acuity is the opposite of what we see in the delusional.
His actions don't fit. Jesus' miracles, if they occurred, validate His claims. Even critics who dismiss the miracles must account for why eyewitnesses believed they occurred. The lunatic hypothesis requires that Jesus' delusions somehow produced the appearance of supernatural power—a difficult pill to swallow.
"The officers answered, 'No one ever spoke like this man!'"
— John 7:46 (ESV)
The Uniqueness of Jesus' Claims
It's worth noting that Jesus' claims to deity are unique in religious history. Other religious founders claimed to be prophets (Muhammad), enlightened teachers (Buddha), or reformers (Luther). None claimed to be God incarnate with the consistency and centrality that Jesus did.
This uniqueness counts against the lunatic hypothesis. If claiming to be God were a common delusion, we might expect many examples. But Jesus stands alone. His claims are not the typical product of religious enthusiasm or mental illness but something unprecedented.
Option 3: Lord
If Jesus' claims were true, He is exactly who He claimed to be: Lord and God. This option alone makes sense of all the data.
This Option Fits the Evidence
His character is explained. If Jesus is God incarnate, His moral perfection, authority, and integrity make perfect sense. His character fits His claims.
His teaching is explained. If Jesus is God, He has the authority to teach as He did—to speak on His own authority, to make absolute claims, to demand ultimate allegiance. His teaching fits His claims.
His miracles are explained. If Jesus is God, the supernatural events of His ministry—including His resurrection—are not only possible but expected. His power fits His claims.
His impact is explained. If Jesus is God, the transformation of individuals and societies through faith in Him makes sense. His fruit fits His claims.
His death and resurrection are explained. If Jesus is God, His death becomes the atoning sacrifice Scripture presents it as, and His resurrection becomes the vindication of His claims. His salvation fits His claims.
Insight
The "Lord" option is not just one possibility among three—it's the only option that makes coherent sense of all the evidence. The liar and lunatic hypotheses require us to explain away the very evidence that makes Jesus compelling. The Lord hypothesis allows all the evidence to stand and provides a unified explanation for it all.
Objections to the Trilemma
"Maybe Jesus Never Made These Claims"
Some argue that Jesus' divine claims were invented by the early church—the real Jesus was just a wise teacher, and His followers later elevated Him to divine status.
We addressed this objection in previous lessons. Briefly:
The claims are too early. Divine claims appear in our earliest sources (Paul's letters, written within 20 years of the crucifixion) and show signs of even earlier origin (pre-Pauline hymns and creeds).
The claims are too pervasive. Jesus' divine claims pervade all Gospel sources—Mark, Q, M, L, and John. Removing them requires removing virtually the entire tradition.
The claims caused the response. The early church's worship of Jesus requires explanation. Jewish monotheists don't spontaneously start worshiping a human. Jesus' own claims prepared the way.
The claims fit the context. Jesus' claims make sense in first-century Judaism in ways a later Gentile invention wouldn't. They use Jewish categories, engage Jewish debates, and provoke Jewish responses.
"Maybe He Was Just a Legend"
Some suggest Jesus never existed or was so obscured by legend that we can't know anything about Him.
This is fringe scholarship rejected by virtually all historians, including skeptics. The evidence for Jesus' existence is strong: multiple independent sources (Christian and non-Christian), early dating, and the emergence of Christianity itself, which requires an adequate cause.
"Maybe There Are Other Options"
Some philosophers have suggested additional categories: "Legend" (Jesus' claims were legendary developments) or "Guru" (Jesus was a mystical teacher whose claims shouldn't be taken literally).
But these collapse into the original three:
"Legend" either claims Jesus didn't make divine claims (which the evidence refutes) or accepts that He did but dismisses them (which leaves us with liar, lunatic, or Lord).
"Guru" suggests Jesus made divine claims but didn't mean them literally. But this makes Him either a deceiver (if He knew His followers would take them literally) or a poor communicator (if He didn't). Neither fits Jesus' evident character and teaching ability.
The Force of the Argument
The trilemma doesn't prove Jesus is Lord—but it eliminates the comfortable middle ground. You can't dismiss Jesus' claims while praising His teaching. You can't honor Him as a great man while rejecting His central message. You must decide: deceiver, deluded, or divine?
And when you examine the options honestly, only one makes sense. The liar hypothesis requires us to believe that the most morally influential person in history was a deliberate fraud. The lunatic hypothesis requires us to believe that the wisest teacher in history was mentally ill. Only the Lord hypothesis allows Jesus to be who He so evidently was: a person of supreme moral character, profound wisdom, and supernatural power who was exactly who He claimed to be.
"Jesus said to them, 'But who do you say that I am?' Simon Peter replied, 'You are the Christ, the Son of the living God.'"
— Matthew 16:15-16 (ESV)
Responding to the Trilemma
The trilemma demands a response. Neutrality is not an option; Jesus' claims are too significant to ignore. As you consider the evidence, recognize that this is not merely an intellectual exercise but a life-determining decision.
If Jesus is Lord:
He deserves your worship. Not admiration from a distance but the full devotion of your heart, soul, mind, and strength.
He deserves your trust. His claims about salvation, forgiveness, and eternal life are true. You can stake your life on them.
He deserves your obedience. His teachings are not suggestions but commands from the Lord of the universe. They require our submission.
He deserves your allegiance. Above family, career, comfort, and life itself, Jesus claims first place. He is worthy of it.
The disciples who walked with Jesus came to this conclusion. Thomas, initially skeptical, finally declared, "My Lord and my God!" (John 20:28). That confession remains the appropriate response to Jesus—the only response that fits who He is.
Conclusion: No Middle Ground
Jesus doesn't allow us the comfort of vague admiration. His claims are too specific, too central, too radical. He claimed to be God, and that claim must be reckoned with.
The options are stark: a liar who deceived millions, a lunatic who sincerely believed a delusion, or the Lord who spoke truth about Himself and the universe. The evidence points overwhelmingly to the third option. Jesus' character, teaching, miracles, death, and resurrection all cohere with His claims rather than contradicting them.
The trilemma brings us to a point of decision. We cannot remain neutral observers, admiring Jesus from a safe distance. We must either reject Him as a fraud or fraud—or fall at His feet with Thomas and confess, "My Lord and my God!"
What will you say?
"And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved."
— Acts 4:12 (ESV)
Discussion Questions
- Why is "good moral teacher" not a valid option for understanding Jesus? How does the nature of His claims eliminate this middle ground?
- Consider the "liar" hypothesis. What evidence argues against Jesus being a deliberate deceiver? Why doesn't His character, death, or impact fit this option?
- Some critics argue that the trilemma presents a false choice—that Jesus never made divine claims, or that His claims shouldn't be taken literally. How would you respond to these objections?
