1 Corinthians 13:9-12: Why We Know Only in Part
Short answer: Fallibilism, in a Christian sense, is the honest recognition that our knowledge is real but incomplete. Paul writes in 1 Corinthians 13:9, "For we know in part and we prophesy in part". That does not mean we cannot know anything truly; it means we do not know everything fully, and our grasp of even revealed truth is partial this side of glory. Verse 12 promises a day when partial knowledge gives way to full knowledge, so the proper response now is not paralysis or cynicism but humility, teachability, and love. Fallibility is a fact about us, not a flaw in God or in what he has revealed. It calls us to hold convictions firmly where Scripture speaks clearly, and loosely where we are inferring, guessing, or repeating tradition.
What 1 Corinthians 13:9-12 actually says
The chapter sits in the middle of Paul's long correction of a divided, gifted, and proud church. Chapters 12 and 14 deal with spiritual gifts; chapter 13 is the famous love chapter between them. But 1 Corinthians 13 is not a wedding poem detached from the letter. It answers a church that prized impressive knowledge and spectacular gifts. Paul does not despise knowledge; he relativises it. He says, in 1 Corinthians 13:9, "For we know in part and we prophesy in part". Even the most reliable human knowing and speaking on God's behalf is partial. That is a stunning claim in a church obsessed with status.
Verse 10 then adds the contrast: when the perfect comes, the partial will be done away. Paul is not despising the partial; he is putting it in its place. The partial is real, useful, and God-given, but it is not final. Notice the verb tense logic throughout the chapter. Love never fails, but prophecies will be done away, tongues will cease, knowledge will be done away. The gifts and even our knowing are temporary scaffolding. They are not lies; they are incomplete. A scaffold is not a building, but you still need it while the building goes up.
Verse 11 gives a homely illustration: when Paul was a child, he spoke, thought, and reasoned like a child; when he became a man, he put away childish things. This is not an insult to children. It is an argument from ordinary development. We grow. Our present understanding is genuinely ours, but it is the understanding of spiritual childhood compared to what is coming. Anyone who has taught a child knows that a child's knowledge is not false; it is simply small. Paul is saying that our most confident theological reasoning now is, by comparison, the reasoning of a child about to grow up.
Verse 12 supplies the controlling image: now we see in a mirror dimly, but then face to face; now we know in part, but then we will know fully, even as we are also fully known. Ancient mirrors were polished metal, not glass, so the image was real but imperfect. That is the exact proportion Paul wants. Our knowledge is not nothing, and it is not everything. And the final clause is humbling: we are already fully known by God. We are not the ones doing the final assessment. God knows us through and through while we squint. Fallibility is the posture of a creature who is known better than he knows.
Fallibility is not the same as skepticism
A common mistake is to hear the word fallible and assume it means we cannot know anything at all. That is skepticism, and Paul does not teach it. He says we know in part, not that we do not know. If I know part of a map, I still know a real road. Partial knowledge is still knowledge. The verse would be nonsense if it meant nothing could be known, because then Paul could not tell us even that much. Fallibilism says our knowing is genuine but limited; skepticism says our knowing is illusory. The two are not the same, and confusing them wrecks the Christian life.
This matters because some people use humility as a cover for unbelief. They say we can never be sure of anything, so they never submit to anything. But Paul is writing as an apostle who expects his teaching to be obeyed. He commands, corrects, and rebukes throughout the letter. His humility about partial knowledge did not stop him from saying, in 1 Corinthians 8:1, that "Knowledge puffs up, but love builds up". That is a hard, confident claim. So the fallible apostle is also the authoritative apostle. His point is not that we should doubt everything but that we should hold everything with the self-awareness of a creature.
The opposite error is equally common: the person who treats his own conclusions as if they were God's own voice. This is the Corinthian problem. They were confident, gifted, and sure. Paul's answer is not to destroy their confidence in the gospel but to deflate their confidence in themselves. A fallibilist can still be certain that Jesus rose from the dead and that God is faithful, because those are God's own pronouncements. He simply refuses to confuse his own reading, his own tradition, and his own preferences with the voice of God. That refusal is not weakness; it is honesty.
So the Christian version of fallibilism is a middle path. On one side is the cynic who says we can know nothing. On the other is the dogmatist who says we can know everything with the same certainty. Paul walks between them: we know truly, but in part. We should speak and teach with conviction where God has spoken, and with humility where we are inferring, applying, or guessing. That is not relativism. It is the difference between the foundation and the scaffolding. The foundation is Christ and his word; the scaffolding is our present, partial grasp of it.
Why our knowledge is partial
The first reason our knowledge is partial is that God is infinite and we are not. Deuteronomy 29:29 says, "The secret things belong to Yahweh our God; but the things that are revealed belong to us and to our children forever, that we may do all the words of this law." God has told us what we need. He has not told us everything. There is a boundary, and it is drawn by God's wisdom, not by our failure. Moses does not treat that boundary as a problem to be solved but as a fact to be accepted. We are given enough to obey, not enough to satisfy every curiosity.
The second reason is our own limits as creatures. We are finite, located in time and place, shaped by language and culture. We reason slowly and sometimes badly. Sin adds a further distortion: we are prone to read our own interests into God's word. So even where God has spoken plainly, our reception of it is uneven. This is why Proverbs 3:5-7 says, "Trust in Yahweh with all your heart, and don't lean on your own understanding." The proverb is not anti-intellectual. It is anti-self-trust. Leaning on your own understanding is exactly what a fallible person should not do, precisely because his understanding is fallible.
The third reason is that we see in a mirror dimly, as verse 12 puts it, and the dimness is not only intellectual but moral and relational. We know God truly, but we know him as children know a father, not as adults know a lifelong friend face to face. Our knowledge is mediated by Scripture, by the Spirit, by the church, and by our own limited experience. Each of those channels is good, and each is partial. That is why the same Bible read by sincere believers yields different conclusions on secondary matters. The text is not confused; we are.
None of this should drive us to despair, because the same verse that says we know in part also says we will know fully. The partial is not the end. God is not content to leave his children squinting forever. The promise of verse 12 is that partial knowledge gives way to face to face knowledge. So the limitations of this age are temporary, purposeful, and bearable. They are meant to keep us humble, dependent, and hungry, not to make us doubt that God has spoken at all.
How fallibilism changes the way we argue
If we know in part, then our disagreements should have a different texture. We can contend for the truth without pretending that our side is infallible. Paul models this in 1 Corinthians 8-10, where he addresses food offered to idols. In 1 Corinthians 8:1-3 he writes, "Now concerning things sacrificed to idols: We know that we all have knowledge. Knowledge puffs up, but love builds up." Notice what he does not do. He does not say the weaker brother is right about the idol. He says knowledge without love is corrosive, and love is the real test of whether we know God at all.
This changes how we treat people we think are wrong. A fallibilist can still say, clearly, that a view is error. But he says it as one who might also be wrong about something else, and who has no right to contempt. James 1:5 says, "But if any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him." James assumes that wisdom is available and that we often lack it. The right response to lack is to ask, not to bluff. A teacher who admits he does not know is more trustworthy than one who pretends he always does.
James goes on in verses 6-8 to warn about the double-minded man who wavers. So the biblical picture is not endless uncertainty. We ask in faith, we receive real wisdom, and we act on it. But we act with the awareness that we are still learning. That combination of conviction and humility is rare and beautiful. It is what makes a person safe to disagree with. You can correct him without fear, and he can correct you without arrogance, because neither of you is pretending to be God.
Practically, this means we should learn to say three different things. Where Scripture is clear, say it and mean it: Jesus is Lord, he died and rose, he is coming again. Where Scripture is silent or ambiguous, say so: this is my best reading, and I may be wrong. Where we are merely repeating our tradition or preference, say that too: this is how my church does it. The confusion of those three categories is the source of most needless conflict. Fallibilism is simply the discipline of keeping them straight.
The humility of Job and the limits of our explanations
Perhaps no one in Scripture learns partial knowledge more painfully than Job. For chapter after chapter he has argued his case, and his friends have argued theirs with great confidence. Then God speaks, and the whole argument collapses. In Job 42:1-6 Job answers Yahweh. That answer is not a new argument; it is a surrender. He has heard of God by the hearing of the ear, but now his eye sees him, and he repents in dust and ashes. The book does not tell us the reason for Job's suffering, and that silence is the point.
Job's friends had all the confident explanations. Suffering means sin, they said. Job, they insisted, is hiding something. They were not entirely wrong in general terms; Scripture elsewhere connects sin and suffering. But they were completely wrong about Job in this case, and their confident partial knowledge made them cruel. God says at the end that they had not spoken rightly of him. The lesson is not that doctrine does not matter. It is that our doctrine, however true, does not entitle us to sit in judgment on God's hidden purposes.
This is where fallibilism becomes pastoral rather than merely theoretical. A person who knows in part can sit with a sufferer without explaining the unexplainable. He can say, with Job, that God is wise and good, and still admit that he does not know what God is doing. That is far more helpful than a tidy theory that crushes the sufferer. A partial knowledge that knows its limits can comfort; a partial knowledge pretending to be complete usually wounds. The difference is love, which is exactly what 1 Corinthians 13 puts at the center.
Job's repentance is not repentance for thinking. It is repentance for speaking beyond his station. He had demanded answers, and God gave him better than answers: himself. That is the pattern for every fallible knower. The goal of theology is not to master God but to be mastered by him. We study, we argue, we write, and we should do it with all the rigor we can. But we do it on our knees, aware that the God we study is the God who knows us fully, and that our best sentences about him are the stammering of a child.
Love is the point, not certainty
Return to the context of 1 Corinthians 13. The chapter ends with faith, hope, and love abiding, the greatest being love. That placement is deliberate. In a church competing over knowledge and gifts, Paul says the mature thing is not the most impressive thing. It is the loving thing. If I understand all mysteries and have all knowledge but have not love, I am nothing. The more certain I am and the less loving I am, the further I have drifted from the point. Fallibility is meant to produce love, not just intellectual modesty.
Why does love follow from knowing in part? Because if I know I am partially blind, I cannot despise the person who sees the part I have missed. I need him. The Corinthian church was full of members who thought they did not need anyone. Their knowledge puffed them up. Paul's cure is a community where each member knows he is incomplete and therefore needs the others. Fallibility is not just an individual virtue; it is the engine of Christian community. The body works because no member is the whole body, and no member's knowledge is the whole truth.
This also gives us patience with ourselves. If you have ever been troubled by how little you understand, Paul says that is not a defect to be ashamed of; it is the human condition, and it will change. You will know fully, even as you are fully known. That is a promise, not a rebuke. The child does not despair because he is not yet an adult. He grows. Your partial knowledge now is the real, God-given beginning of a knowledge that will one day be complete. So keep asking, keep reading, keep repenting, and keep loving.
The final test of a fallibilist is not whether he is unsure of everything but whether he is humble and loving with those who differ. Anyone can be humble when everyone agrees with him. The real proof is in the disagreement, the correction, the argument that goes badly. There, the person who knows in part can still speak the truth, receive correction, and hold his tongue when love requires it. That is not weakness. It is the maturity Paul is describing, and it is the shape of a life that is being conformed to Christ.
Living as those who know in part
What does this look like on an ordinary Tuesday? It looks like holding your convictions with an open hand where they are your own conclusions, and with a firm grip where they are God's own words. It looks like listening more than you speak in a disagreement, not because truth does not matter, but because you might learn something. It looks like apologizing when you have been wrong, without feeling that your whole faith has collapsed. Fallibility is freedom: you do not have to be right about everything to be faithful to the One who is.
It also looks like a different kind of confidence. The person who cannot admit error is often secretly afraid that his whole system will fall apart if one piece is wrong. The fallibilist has a foundation that does not depend on his own perfection. Christ is the foundation, and Christ has not staked his faithfulness on my ability to be right about every secondary thing. So I can be corrected without being destroyed. That is a stable place to stand. It is the difference between resting on the Rock and balancing on your own conclusions.
Finally, fallibilism should make us eager for the day when partial knowledge ends. The Christian hope is not that we will finally be proven right in every argument. It is that we will see him face to face and know him as we are known. Everything we do now, all our study and teaching and debate, is preparation for that. The best theological work is done by people who long for the day when theology will be unnecessary because the One theology is about will be present. Knowing in part is not a reason to stop knowing. It is a reason to keep going, toward the face.
Biblical fidelity check
What 1 Corinthians 13:9-12 establishes is clear: our present knowledge is partial and will be completed. It establishes that this partiality is temporary, not permanent; that the completion is God's doing, not ours; and that love is the enduring mark of maturity in the meantime. It does not establish that truth is unknowable, that all interpretations are equally valid, that doctrine is unimportant, or that we should stop teaching with conviction. Paul himself teaches with deep conviction in the same letter. The passage humbles the knower, not the knowledge. It relativises our grasp of truth, never truth itself.
A common misreading treats this passage as a warrant for doctrinal indifference. The reasoning goes: since we only know in part, no one can say another view is wrong, so let us all just love each other. But that is not Paul's argument, and it proves too much. If we know in part, we also know in part that some views are wrong, and love itself sometimes requires saying so. The chapter does not abolish discernment; it relativises the pride that so often accompanies it. The misreading replaces the apostle's humility with an indifference he never taught, and it quietly makes love mean agreement rather than self-giving truthfulness.
Other passages that speak to 1 Corinthians 13:9-12
Several nearby passages in the same letter deepen this theme of partial, humble knowledge. Paul's plea for unity in What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application rests on the same assumption that a divided church has mistaken its own partial insight for the whole. The foundation of that unity is described in What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application, where God's faithfulness, not our clarity, is the ground of our calling. For the whole flow of the letter, see 1 Corinthians 1: Called, United, and Boasting in the Lord. And Paul's most sustained treatment of knowledge, freedom, and the limits of both appears in 1 Corinthians 10: Warnings and Freedom.
Frequently asked questions
Does 1 Corinthians 13:9-12 mean we cannot know truth?
No. Paul says we know in part, which assumes we really do know, just not completely. If the verse meant we could know nothing, it could not teach us even that. The parallel is a child's knowledge: real, true, and growing, but not yet mature. So the passage grounds humility, not skepticism. Christians can hold firm convictions because God has genuinely revealed himself, while admitting that their grasp of that revelation is partial and often mixed with their own assumptions.
Is fallibilism the same as relativism?
No, and the difference matters. Relativism says truth depends on the person or culture, so no view is better than another. Fallibilism says truth is real and objective, but our hold on it is limited and sometimes mistaken. A fallible mathematician can still get a sum right; he just knows he is capable of error. In the same way, a fallible Christian can know the gospel is true while holding his secondary opinions with appropriate caution. Relativism removes the standard; fallibilism humbles the student.
How does knowing in part affect how I treat other believers?
It should make you slower to contempt and quicker to listen. If you only see part of the picture, the person who disagrees may be seeing something you have missed, even if he is wrong overall. Paul ties knowledge directly to love: knowledge puffs up, but love builds up. So the test of your theology is not only whether it is accurate but whether it produces patience, gentleness, and a willingness to be corrected. That is the maturity 1 Corinthians 13 is describing.
