Liar, Lunatic, or Lord

C. S. Lewis’s famous argument is often reduced to a slogan: Jesus must be liar, lunatic, or Lord. Used that way, it can sound like a verbal trap. Its better use is narrower and stronger. It challenges the comfortable claim that Jesus was a great moral teacher but not the Lord Christians confess.

That middle position only works if Jesus taught ordinary moral wisdom while others later exaggerated him. But the New Testament does not present a safe teacher. It presents someone who forgives sins by his own authority, claims unique relation to the Father, speaks of existing before Abraham, receives worship, and is proclaimed risen and enthroned. If that portrait is historically grounded, “good teacher but not Lord” will not bear the weight placed on it.

The trilemma is downstream from the deity of Christ. First ask what Jesus is reported to have said and done. In Mark, he forgives sins and then heals the paralytic so the crowd may know that the Son of Man has authority on earth to forgive sins. In John, he says the Son must receive the same honor as the Father, speaks of himself before Abraham, and receives Thomas’s confession, “My Lord and my God.”

Those are not the claims of a teacher who merely says, “Be kind.” They are claims about identity and authority. A person may reject them, but should not domesticate them.

A careful answer must include the option Lewis’s shorthand can appear to skip: perhaps the Gospels are legendary or unreliable. Many modern critics do not say Jesus was lying or deluded; they say the church put divine claims into his mouth later.

That objection should be answered directly, not bypassed. The case for the reliability of the New Testament, the public resurrection witnesses, and the early worship of Jesus matters here. If the documents are late legend, the trilemma does not get started. If the high claims are early and rooted in the apostolic witness, then the “mere teacher” option becomes the least serious answer.

Christianity does not ask people to infer Jesus’ lordship from large claims alone. The apostles point to God’s public verdict on Jesus: he was crucified, raised, and exalted. Peter’s Pentecost conclusion is not that Jesus survived death, but that God made the crucified Jesus “both Lord and Christ.”

That is why the trilemma belongs beside resurrection as messianic vindication. The resurrection does not endorse an abstract teacher. It vindicates this claimant, with these words, this authority, this death, and this commission.

Do not use “lunatic” as an insult, and do not use the trilemma to corner someone rhetorically. Ask the real question: what category can honestly contain Jesus?

If someone thinks the sources are unreliable, talk about history. If someone thinks Jesus made no divine claims, read the texts. If someone grants the portrait but still calls him only a good teacher, the Lewis argument exposes the inconsistency. The issue is not whether Jesus is inspiring. The issue is whether his claims are false, misreported, or true.
