Short answer: 1 Corinthians 6:18–20 does not address kissing directly. It commands believers to flee sexual immorality and gives two reasons: the body is a temple of the Holy Spirit, and the believer was bought with a price and is not their own. That means the question is not simply where a line sits, but who owns the body and what it is for. Kissing before marriage falls under that ownership and purpose, so it should be pursued with conscience, honesty, and a aim to glorify God rather than to see how close to a boundary one can stand.
A pastoral letter, a slogan, and a body that belongs to God
First Corinthians is a letter, not a sermon or a rulebook. Paul writes to a congregation he had founded in a large port city crowded with temples, trade and competing moral codes. The occasion is concrete: reports of problems in the church and questions the Corinthians had sent him. Chapters 5 through 7 move through sexual sin in the congregation, lawsuits between believers, and then those written questions. Our passage sits in the middle of that run, so it is an argument inside a conversation, not a standalone motto. Reading it as a free-floating rule about kissing misses the debate Paul is actually having with people who thought the body did not matter.
The literary shape here is deliberate. Paul issues a command to flee sexual immorality, then quotes a saying his readers apparently prized, that every sin a man does is outside the body, and he corrects it: sexual immorality is a sin against one's own body. Then he gives two grounding reasons, both about identity and ownership. The believer's body is a temple of the Holy Spirit, and the believer was bought with a price. Just before this, in 6:12–17, he answers the slogan that all things are lawful and appeals to the believer's union with Christ. The quoted line in verse 16 reaches back to Genesis, where sexual union makes two people one flesh. That is why Paul treats bodily sin as spiritual, not merely physical.
First Corinthians 7:1–2 follows immediately and shifts to the Corinthians' own written claim, that it is good for a man not to touch a woman. Paul answers by directing sexual intimacy into marriage because of sexual immoralities. So the whole stretch assumes a new covenant community living in a city that treated the body as religiously irrelevant. Paul dismantles that assumption. Two things stay central and should shape how this passage is applied: the command to flee is real, and the grounding is Christ's purchase, not a purity record. Readers who have sinned sexually, or been sinned against, are addressed here as people Christ bought and the Spirit indwells.
Flee, and remember whose you are
The command in 6:18 is not advice to keep temptation at a comfortable distance. It is a word of urgent motion: run. Paul does not tell the Corinthians to stand near the fire and reason with it, and he does not suggest that willpower plus time will do. The word he chooses assumes danger is already close. He then names the sin broadly, as sexual immorality, and the next chapter shows how wide that net is when it offers the remedy of each man having his own wife. Anything sexual outside marriage falls inside the warning. Fleeing may mean leaving a room, ending a conversation, or changing a habit before the moment arrives.
Paul then quotes a saying the Corinthians apparently repeated, that every sin a man does is outside the body, and he refuses its conclusion. He answers that the immoral person sins against his own body. The reason is what the body now is. In 6:19 he calls it a temple of the Holy Spirit who is in you, a dwelling place, not a private possession. Then come the commercial words: you were bought with a price, and you are not your own. A temple belongs to the God who fills it; purchased property belongs to the one who paid. The body is therefore for God's glory, not the owner's use.
These verses carry a particular tenderness for anyone who has failed here or been sinned against. The ground of belonging is not a record of purity but a purchase already made. Paul does not say the body becomes a temple once the past is clean; he says it is one, because the Spirit was given. That does not make the sin small, and fleeing is still the command. But the call to glorify God in your body rests on being bought, not on deserving to be. Forgiveness and belonging begin in Christ's payment, and the command to run follows from being his.
Your body is not your own
Paul has just answered a slogan the Corinthians liked: that all things are lawful for him. He agrees in part, then draws a line, because the body is not made for immorality but for the Lord, and the Lord for the body. In 6:16–17 he sets two unions side by side. Joining a prostitute makes one body, since the two become one flesh; joining the Lord makes one spirit. The quotation comes from Genesis, where sexual union creates a real bond. That is why Paul treats bodily sin as a spiritual matter, not a private physical one. What you do with your body says something about who you are joined to.
The commands in 6:18–20 rest on two facts, not on a purity score. First, the Holy Spirit lives in the believer, so the body is a temple, a dwelling place rather than a private possession. Second, you were bought with a price, so you are not your own. The negative command is to flee sexual immorality, and the positive one is to glorify God in the body. Notice that Paul does not name kissing here. He does something larger: he establishes ownership and purpose. Any question about physical intimacy before marriage has to be answered inside that framework, not around it.
The argument continues into chapter 7, where Paul takes up what the Corinthians had written to him. They claimed it was good for a man not to touch a woman; Paul answers that because of sexual immoralities each man should have his own wife and each woman her own husband. Intimacy is directed into marriage, not treated as a religiously irrelevant appetite. This city assumed the body did not matter spiritually. Paul dismantles that assumption. For anyone who has already sinned sexually or been sinned against, the ground here is grace: you belong to Christ because he bought you, and that purchase, not a spotless record, is where forgiveness and belonging begin.
Where the line falls before marriage
Paul writes to a church that had turned freedom into a slogan. In 6:18 he commands flight, not negotiation: flee sexual immorality. Then in 6:19–20 he gives the reason, that the body is a temple of the Holy Spirit and that the believer was bought with a price. Careful readers agree on the core: sexual intercourse belongs inside marriage, and the body is not ours to dispose of as we please. They disagree on where the line sits before marriage, and the text itself never draws a checklist of gestures. It names sexual immorality and leaves the reader to apply that in wisdom.
One reading says any deliberate arousal of sexual desire before marriage already partakes of what Paul warns against, so kissing is governed by the command to flee and belongs to conscience. Another reading observes that Scripture nowhere forbids kissing, that Paul's argument in 6:15–16 concerns union with a prostitute, and that the temple language calls for bodily stewardship rather than a rule about affection. Both are trying to obey the same verses. What stays central is that the body is the Lord's, that Christ is honored in it, and that love for a future spouse weighs the actual pull toward sin rather than the minimum a rule permits.
These verses do not ground belonging in a record of purity. Paul says believers were bought with a price, and that purchase happened while they were still sinners. Readers who have sinned sexually, and readers who were sinned against, are not sorted by what was done to them or by them. The call to glorify God in the body is addressed to people already owned by Christ, not to people earning their place. That is why the passage can be both serious about sexual sin and gentle with the ashamed: forgiveness and belonging rest on what Christ paid, not on what we preserve.
Bought with a price: why your body belongs to Christ
Paul moves from the union of bodies in verse 16 to a sharper contrast in verse 17: the one joined to the Lord is one spirit with him. Then comes the command, short and urgent, to flee sexual immorality. Notice what Paul does not say. He does not say the body is unimportant, so do as you like. He says the opposite: the body is a temple of the Holy Spirit who is in you, given by God. The command to flee rests on something already true of the believer. The Spirit has been given, and the body has become God's dwelling. Purity here is not self-improvement. It is living out a union Christ has already established.
The gospel is present in the words bought with a price. Paul does not ground the call to purity in a record of good behavior, but in a purchase. Christ paid for a people, and that purchase is what makes them God's. So the command to glorify God in the body is an invitation, not a threat. It says: you belong to someone who bought you. That is why verse 20 can end with which are God's. The belonging came first. The obedience is the shape that belonging takes in ordinary life, including in how a Christian handles desire, touch and romance before marriage.
This matters most for readers who have already sinned sexually, or who have been sinned against. Paul does not say the body is a temple only if you have kept it clean. He says the Spirit is in you, and you were bought with a price. Failure is met by the same purchase and the same Spirit, not by expulsion. That does not make sin small; it makes grace large. The call to flee is still real, and it is spoken to people Christ has already claimed. Repentance is possible because the price has been paid, and belonging is secure because Christ secured it.
What faithful response looks like in ordinary life
Start with what the text says about you, not with a list of rules. Paul asks whether the Corinthians know that their body is a temple of the Holy Spirit given to them, and that they are not their own, because they were bought at a price (6:19–20). That changes the question a dating couple asks. The question is not how far we can go before a line is crossed, but what honors the one who purchased us. A rule can be negotiated in the moment; an identity cannot. If the Spirit actually lives in you, the practical question becomes where you are taking his dwelling place, and why.
The command is blunt: flee sexual immorality (6:18). Fleeing is not the same as standing firm, and it is practical. It means arranging your life so that certain situations do not happen: the empty apartment, the late night, the privacy you know you cannot handle. Decide those boundaries in advance, when desire is low and thinking is clear, and then talk honestly with the person you are dating. Ask what your physical affection is for and where the relationship is actually heading, because this passage cares about the direction of your body, not only about a single act.
If you have already failed, or if someone has sinned against you, the ground of your standing is not a clean record. It is the price that was paid, and the Spirit who was given to dwell in you. Confess honestly and do not despair; belonging was purchased for you, not earned by you. What this text does not promise is a happy marriage or a painless relationship as a reward for good boundaries. It promises God's presence and calls you to his glory, and it leaves the outcomes in his hands.
Biblical fidelity check
Read closely, 1 Corinthians 6:18–20 carries interpretive risks. Paul commands flight from sexual immorality, then quotes a Corinthian slogan about sin being outside the body and corrects its conclusion. The images of temple, purchase and ownership are commercial and worship language, not a general rulebook for gestures. The passage names sexual immorality, which the letter ties to union outside marriage, and gives no checklist about kissing. Treating the temple image as a broad mandate for bodily health stretches Paul's specific argument about union with a prostitute.
The real disagreement is where the line falls before marriage. Some readers treat any intimacy that deliberately stirs sexual desire as the immorality this passage warns against, so kissing becomes a matter of conscience under the command to flee. Others note that Scripture never forbids kissing and that Paul addresses sexual union, so couples set wise boundaries without calling a kiss sin. What stays central is that the body is not the believer's own, Christ is honored in it, and wisdom weighs the actual pull toward sin rather than the minimum a rule allows.

Frequently asked questions
Does the Bible actually say that kissing before marriage is a sin?
No, this passage never mentions kissing, and it does not list physical affection before marriage as a sin. Paul commands believers to flee sexual immorality, which he treats as joining one's body to another outside the one-flesh union God intends for marriage. His concern is sexual union, not every expression of affection. The passage calls your body a temple of the Holy Spirit and says you were bought with a price, so it asks you to glorify God in your body. That is a wisdom principle for how you steward affection, not a verse that names kissing as sin.
How far can a Christian couple go physically before marriage before it counts as sin?
This passage does not draw a line at some distance short of sex; it commands you to flee sexual immorality, and in 1 Corinthians 7:2 the answer to desire is marriage, not a nearer approach. Paul grounds the command in who you are: your body is a temple of the Holy Spirit, and you were bought with a price (6:19–20). So the question shifts from how close you can get to how you use a body that belongs to God. Practically, that means setting your boundary well before the edge, because the text tells you to run, not to negotiate.
Why does Paul say that sexual sin is a sin against your own body?
Paul grounds the claim in union: the one joined to the Lord is one spirit with him, so the body belongs to Christ rather than to the self, and sexual immorality pulls the body toward a rival union. He sets it against other sins as uniquely body-involving, then explains why the body matters so much: it is a temple of the Holy Spirit, received from God, and bought at a price. Because you are not your own, the body is the place where God is glorified.
