What does the Bible say about dating a non-Christian? Being unequally yoked, explained

The Bible never mentions dating, but it does speak to marriage. Paul says a widow may remarry "only in the Lord" (1 Corinthians 7:39), which most Christians apply to every believer, and he warns against being "unequally yoked" with unbelievers (2 Corinthians 6:14). So many Christians conclude you shouldn't date someone you couldn't marry. If you're already married to an unbeliever, Paul says to stay if your spouse is willing.

What "unequally yoked" means

¹⁴Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? ¹⁵And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? ¹⁶And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.

A yoke is the wooden beam that joins two animals so they can pull a plow together. The Greek word Paul uses means to be yoked with a different kind (Strong's 2086). It echoes the laws against mixing different kinds of animals (Leviticus 19:19, where the Greek Old Testament uses a related word) and plowing with an ox and a donkey together (Deuteronomy 22:10). The two differ in size, strength, and pace, so under one beam they can't pull the same way.

A few KJV words: concord means harmony, Belial is a Hebrew word for worthlessness used here as a name for Satan, and an infidel is simply someone without faith, not a cheating partner.

Notice where Paul goes next: verse 16 turns to idols, a danger he had already warned this church about (1 Corinthians 8:10, 10:20-21). John Calvin argued that the command is too broad to be only about marriage, since Paul is warning against sharing in idolatry, but he held that the same principle rules out marrying an unbeliever. Christians have long applied it that way, since marriage is the closest yoke two people can share.

What Paul doesn't mean is that Christians should avoid non-Christians. In 1 Corinthians 5:9-10 he says that avoiding every immoral, greedy, or idol-worshiping person outside the church would mean leaving the world. Friendship, work, and kindness across belief are normal Christian life. Most readers take the yoke to mean a binding partnership that pulls you away from God, not everyday contact.

Can a Christian marry a non-Christian?

The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord.

Paul is writing about widows. Bound by the law means bound by marriage. Once her husband has died, she can marry whoever she chooses, with one limit: only in the Lord. Most interpreters across church traditions read this as marrying a fellow believer. It is the most direct New Testament word on whom a Christian should marry.

It fits an older pattern. Israel was told not to intermarry with the nations of Canaan because those marriages would turn their children away from God, a reason about faith, not ethnicity (Deuteronomy 7:3-4). In old age, Solomon's wives turned his heart after other gods (1 Kings 11:4). Outsiders who embraced Israel's God, like Ruth (Ruth 1:16), were welcomed.

Church rules differ. The Orthodox Church does not permit an Orthodox Christian to marry someone who isn't baptized. The Catholic Church treats such a marriage as invalid unless church authorities grant a dispensation, on condition that the Catholic partner promises to guard their faith and do all they can to raise the children Catholic (canons 1086 and 1125). The Episcopal Church asks only that at least one partner be baptized.

Is it wrong to date a non-Christian? How Christians differ

Modern dating didn't exist in the biblical world. Marriages were usually arranged through families; Genesis 24, where Abraham's servant finds a wife for Isaac, is a typical scene. So Christians have to reason from the marriage passages to dating, and they don't all reason the same way.

• Date only someone you could marry. Many evangelical pastors teach this. Dating exists to find a spouse, so if you shouldn't marry an unbeliever, don't start down that road with one. Friendship is fine; romance is where the yoke begins.
• The line is marriage. Some Christians note that the clearest command (1 Corinthians 7:39) is about marriage and treat casual dating as a matter of wisdom, not sin. They still counsel caution before a relationship grows serious.

Two verses people quote about dating

Can two walk together, except they be agreed?

In its setting, this verse opens a string of cause-and-effect questions, such as a lion roaring because it has prey. They build to Amos's point: he prophesies because God has spoken (Amos 3:8). Several modern translations render it as two people who have agreed to meet. Still, the picture holds: walking together for years takes a shared direction.

Keep thy heart with all diligence; for out of it are the issues of life.

A father says this to his son (Proverbs 4:20). Keep means guard, and issues means springs or sources: what flows out of your heart shapes where your life goes. In a relationship, guarding your heart means deciding what you believe about marriage before your feelings run deep, not after.

What about "missionary dating"?

This means dating a non-Christian in the hope they'll come to faith. God can draw anyone to himself, but pastors raise real concerns. Someone may profess faith to keep the relationship rather than because they believe, and the pull can run the other way, with the believer going quiet about Jesus to keep the peace.

Even within marriage, Paul admits a believer can't know whether they will win their spouse (1 Corinthians 7:16). Whatever else that verse means, another person's faith isn't yours to control, which makes that hope a shaky reason to start a relationship.

What if you're already married to a non-Christian?

You're far from alone. A 2025 Pew Research Center report found that about 13% of married US adults are in a marriage between a Christian and a religiously unaffiliated spouse. Paul and Peter both wrote to this situation.

¹²But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away. ¹³And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him.

Speak I, not the Lord doesn't mean this is mere opinion. Jesus left no recorded teaching on this case, so Paul gives his own apostolic instruction (compare verse 10). Put away means divorce, and pleased to dwell means willing to live together. The instruction is plain: if your spouse wants to stay, don't leave because of the difference in faith.

Verse 14 adds that the unbelieving spouse is sanctified, or set apart, through the believer, and that the children are holy. That doesn't make your spouse a believer; verse 16 still asks whether you will save them. Most take it to mean the marriage isn't defiling or illegitimate in God's eyes, and that your faith brings God's influence into the home.

Staying is not a call to endure abuse. If you are unsafe, contact the National Domestic Violence Hotline (call 1-800-799-7233 or text START to 88788) and a pastor you trust.

¹⁵But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God hath called us to peace. ¹⁶For what knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?

If the unbelieving spouse insists on leaving, the believer is not under bondage, meaning not bound to hold the marriage together alone. Christians disagree about whether this frees the believer to remarry. Verse 16 can be read as hope (you might win your spouse) or as realism (you can't know, so don't cling at any cost). Either way, it calls for patience, not pressure.

¹Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives; ²While they behold your chaste conversation coupled with fear.

Peter writes to Christian wives whose husbands obey not the word, meaning they haven't accepted the gospel. In the KJV, conversation means way of life, not talk (more in KJV words that changed meaning). Chaste means pure, and fear here means reverence. Christians differ on how the call to submission applies today, but the main point is clear: a spouse may be won without the word, by how you live rather than by constant persuasion. This is counsel for a marriage already made, not a plan for starting one.

There is real hope here. Timothy, one of Paul's most trusted coworkers, had a believing Jewish mother and a Greek father who isn't described as a believer (Acts 16:1). Paul traces Timothy's faith to his mother and grandmother (2 Timothy 1:5). A believing parent's faith can take root in a child even when the other parent doesn't share it.

Questions to ask before dating a non-Christian

• Would I marry this person? If the honest answer is no, ask what the relationship is for.
• Can we share the most important part of my life? Could you pray together, talk openly about Jesus, and keep going to church with their support? Pew found that only 16% of people in religiously mixed marriages talk about religion with their spouse at least weekly, versus 43% in same-religion ones.
• How would we raise children? Baptism, church, and what you'd teach them about God are easier to settle now than later.
• Is my faith growing or shrinking? Notice whether you're hiding parts of it, skipping church, or avoiding the subject.
• Am I waiting for them to change? If the relationship only works once they convert, you're asking a person to become someone else for you.
• Am I afraid of being alone? Fear of loneliness can push anyone toward a relationship. Our pages on loneliness and waiting on God speak to that.

Talk it through, without shame

If you already care about someone who doesn't share your faith, you haven't put yourself outside God's love. Feelings for a kind, good person aren't wicked, and many Christians have stood where you are. Take the question to a pastor, a Christian counselor, or a mature Christian friend who knows you, and ask for honesty, not just reassurance. If you keep turning it over at night, see Bible verses for overthinking.
