What does the Bible say about interfaith marriage?

6 min read

Marriage is a bit like a recipe. You need the right ingredients, the right mix, and above all, avoid risky combinations... like putting chocolate on pickles. And when we talk about interfaith marriage, we often wonder: does the Bible validate this combination or does it raise a divine eyebrow and say, "Uh, not sure that's a good idea?" Spoiler: it's a little more subtle than that.

We explain everything to you, with humor and a good dose of seriousness, in this article which will tell you in black and white what the Bible thinks about this type of union.

The Bible, Marriage, and Different Beliefs: Getting to the Heart of the Matter

what-does-the-bible-say-about-interfaith-marriage

So there you have it. You're a Christian, your other half is of another faith—or not even a believer at all—and you're wondering: Will God look at me strangely if I say "yes"? Maybe you already have your dream mermaid wedding dress in mind, but a deeper question is holding you back. The short answer: it depends. But as you might expect, we're not going to stop there.

The Bible talks about marriage in several places, and like any good book of more than a thousand pages, it has passages that aren't always easy to interpret. But rest assured, we've deciphered it for you.

The Old Testament: rather strict on the issue

In the Old Testament, mixed marriages weren't a joke. God often asked the Israelites not to mix with neighboring peoples. And not for reasons of style or musical taste, mind you, but rather because it risked alienating them from their faith.

Take Deuteronomy 7:3-4, for example. God clearly says not to marry your children to people of different religions, lest they lead them to worship other gods. This was serious at the time: there was no question of diluting the faith.

But be careful, these texts were addressed to a very specific people, in a very specific context. It's not necessarily a copy and paste for today.

The New Testament: Change of tone, but vigilance nonetheless

Along comes Jesus, and with him, a slightly more relaxed tone. But not to the point of saying, "Do what you want." The New Testament doesn't provide a comprehensive manual for interfaith marriages, but there are some key passages.

For example, in 2 Corinthians 6:14 , Paul says, "Do not be unequally yoked together with unbelievers." It sounds harsh when you say it like that. But what does it actually mean? That believers should be careful not to become attached to someone who would distract them from their relationship with God.

So, should you say no to an interfaith marriage? Not necessarily. We'll tell you about it just below.

Mixed marriages: formal prohibition or wise advice?

what-does-the-bible-say-about-interfaith-marriage

Rest assured, the Bible doesn't explicitly say, "You shall not marry an unbeliever." That would be too simple. But it clearly recommends caution. A bit like choosing a short wedding dress : it may seem daring and charming, but requires careful consideration depending on the context. Likewise, if you're in a relationship with someone of another faith, you already know that it's not always a bed of roses.

God's goal: to keep the heart turned towards Him

What God wants is for us to keep our faith alive, to move forward with Him every day. And sometimes, a marriage to someone who doesn't share that faith complicates things a little. Imagine a car with two drivers who want to go in opposite directions. It's bound to get stuck.

So no, God doesn't hate interfaith marriages. But He warns: be careful, it can become quite a challenge.

What Paul says to already mixed couples

In 1 Corinthians 7:12-14 , Paul is addressing couples who are already mixed (yes, even then!). He's basically saying, "If your spouse wants to stay with you despite your faith, don't leave them." In other words: love, peace in the home, that counts too.

He acknowledges that interfaith marriages exist, and he encourages people to approach this situation with wisdom and love. This is far from a categorical rejection, right?

The Practical Challenges of an Interfaith Couple According to the Bible (and Real Life)

what-does-the-bible-say-about-interfaith-marriage

Being in a relationship is an adventure in itself. Being in a relationship with someone who doesn't share your faith is a hike with a few steep hills thrown in. While love can make a simple wedding dress shine, the Bible makes no secret of the fact that it can be complicated.

Child Education: Bible Version or Free Version?

One of the first challenges is education. If you have children, you're probably wondering: do we talk to them about God or not? And if so, which one?

The Bible, of course, recommends teaching the faith from a young age ( Deuteronomy 6:6-7 ). But if your partner isn't on the same page at all, it can quickly become a sensitive topic. One wants to take them to catechism, the other prefers to let them choose when they grow up.

Holidays and traditions: that makes for a busy calendar

Christmas, Easter, Ramadan, Hanukkah… With an interfaith couple, holidays take on a whole new dimension. The Bible doesn't condemn observing other people's holidays, as long as it doesn't take you away from your faith. But it does require patience and a healthy dose of openness.

Prayer and Spiritual Life: Solo or in Pair?

Another challenge: prayer. The Bible speaks a lot about praying together, about supporting each other spiritually. In an interfaith couple, this dimension is sometimes reduced. And even if each person can pray independently, a feeling of spiritual loneliness can be felt.

Love is stronger than anything? The Bible qualifies

Love is beautiful, especially when it's sincere and deep. And the Bible talks about love all the time! But... it also puts in some safeguards. Because sometimes, love can make us close our eyes to essential things.

Love at first sight doesn't erase differences

No, the Bible doesn't say that love is always enough. It says that wisdom is needed. It's good to love each other, but if you spend your life bickering over core values, your relationship is likely to suffer. That's not me saying that, it's experience (and a little bit from Paul too).

Spiritual balance is not a luxury

The Bible reminds us that two people should be able to move forward together. If your faith is important to you, it's natural to want to share it. And if that's not possible in your relationship, it can create frustration. Not because the other person is bad, but because you don't share the same priorities.

Interfaith Marriages in the Bible: There Were Some, and Not Just a Few!

Okay, now you might be thinking, "Okay, the Bible advises against it, but have there been any interfaith marriages?" The answer: yes. And sometimes, even if everything seemed perfect— country wedding dress , beautiful ceremony—the consequences weren't always glorious...

Solomon: The King Who Fell for All Nationalities

King Solomon, son of David, had hundreds of wives (yes, really), and many of them were foreigners. And what happened? They turned him away from his faith ( 1 Kings 11:1-4 ). Not great.

Moral: even the wisest can fall for it.

Ruth and Boaz: The exception that proves the rule?

But there are also beautiful stories. Ruth, a Moabite (so not Jewish), marries Boaz, an Israelite. And their story is so inspiring that it's in Jesus' genealogy. But be careful: Ruth adopted Boaz's faith before their marriage. This is an important detail.

So, what do we do if we are in an interfaith couple?

Let's be honest: the Bible doesn't say it's a mortal sin, but it doesn't encourage it either. It just warns about the possible consequences. So, if you're already in such a relationship or wondering about it—perhaps even dreaming of a lace wedding dress —here are some tips inspired by the Word and common sense.

Have a deep conversation (and not just about the dinner menu)

Before you say yes to a life together, talk about your faith, your values, and what you expect from marriage. This isn't a secondary topic. If you dodge it now, it might come up later... and not smoothly.

Be honest about your expectations

Do you hope your partner will convert one day? Say so. Do you want to pray together? Say so. Honesty is the foundation. Otherwise, you're building on sand.

Keep your faith alive

Don't sacrifice your faith to avoid conflict. The Bible is clear: your relationship with God comes first. And if your partner loves you, he or she will respect that. Link here

Conclusion: What does the Bible say about interfaith marriage? Caution, but not closure

In short, the Bible doesn't cast stones at those who love someone of another faith. But it strongly recommends caution. Why? Because marriage isn't just about feelings. It's a covenant, a journey together, sometimes fraught with pitfalls.

Interfaith marriage is not forbidden, but it is presented as a choice to be made with seriousness, reflection... and a lot of love (real love, not the kind in romantic comedies).

So if you find yourself in this situation, don't be afraid, but be clear-headed. Pray, talk, be honest, and move forward wisely. And above all, remember: God is with you, every step of the way.
