The Old Testament Law commanded the Israelites not to engage in interracial marriage (Deuteronomy 7:3-4). However, the reason for this was not primarily racial in nature. Rather, it was religious. The reason God commanded against interracial marriage was that people of other races were idolaters and worshippers of false gods. The Israelites would be led astray from God if they intermarried with idol worshippers, pagans, or heathens. A similar principle is laid out in the New Testament, but at a much different level: “Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?” (2 Corinthians 6:14). Just as the Israelites (believers in the one true God) were commanded not to marry idolaters, so Christians (believers in the one true God) are commanded not to marry unbelievers. To answer this question specifically, no, the Bible does not say that interracial marriage is wrong.
As Martin Luther King noted, a person should be judged by his or her character, not by skin color. There is no place in the life of the Christian for favoritism based on race (James 2:1-10). When selecting a mate, a Christian should always first find out if the potential spouse is born again by faith in Jesus Christ (John 3:3-5). Faith in Christ, not skin color, is the biblical standard for choosing a spouse. Interracial marriage is not a matter of right or wrong, but of wisdom, discernment, and prayer.
The only reason interracial marriage should be considered carefully is the difficulties a mixed-race couple may experience because of others who have a hard time accepting them. Many interracial couples experience discrimination and ridicule, sometimes even from their own families. Some interracial couples experience difficulties when their children have skin tones of different shades from the parents and/or siblings. An interracial couple needs to take these things into consideration and be prepared for them, should they decide to marry. Again, though, the only biblical restriction placed on whom a Christian may marry is whether the other person is a member of the body of Christ.
1 When the LORD your God brings you into the land you are entering to possess and drives out before you many nations—the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites and Jebusites, seven nations larger and stronger than you— 2 and when the LORD your God has delivered them over to you and you have defeated them, then you must destroy them totally.[a] Make no treaty with them, and show them no mercy. 3 Do not intermarry with them. Do not give your daughters to their sons or take their daughters for your sons, 4 for they will turn your children away from following me to serve other gods, and the LORD’s anger will burn against you and will quickly destroy you. 5 This is what you are to do to them: Break down their altars, smash their sacred stones, cut down their Asherah poles[b] and burn their idols in the fire. 6 For you are a people holy to the LORD your God. The LORD your God has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession.
2 Corinthians 6:14-18
14 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 15 What harmony is there between Christ and Belial[b]? Or what does a believer have in common with an unbeliever? 16 What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: “I will live with them and walk among them, and I will be their God, and they will be my people.” 17 Therefore,“Come out from them and be separate, says the Lord. Touch no unclean thing, and I will receive you.” 18 And, “I will be a Father to you, and you will be my sons and daughters, says the Lord Almighty.”
1 My brothers and sisters, believers in our glorious Lord Jesus Christ must not show favoritism. 2 Suppose a man comes into your meeting wearing a gold ring and fine clothes, and a poor man in filthy old clothes also comes in. 3 If you show special attention to the man wearing fine clothes and say, “Here’s a good seat for you,” but say to the poor man, “You stand there” or “Sit on the floor by my feet,” 4 have you not discriminated among yourselves and become judges with evil thoughts? 5 Listen, my dear brothers and sisters: Has not God chosen those who are poor in the eyes of the world to be rich in faith and to inherit the kingdom he promised those who love him? 6 But you have dishonored the poor. Is it not the rich who are exploiting you? Are they not the ones who are dragging you into court? 7 Are they not the ones who are blaspheming the noble name of him to whom you belong? 8 If you really keep the royal law found in Scripture, “Love your neighbor as yourself,”[a] you are doing right. 9 But if you show favoritism, you sin and are convicted by the law as lawbreakers. 10 For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. 11 For he who said, “You shall not commit adultery,”[b] also said, “You shall not murder.”[c] If you do not commit adultery but do commit murder, you have become a lawbreaker. 12 Speak and act as those who are going to be judged by the law that gives freedom,
1 Now there was a Pharisee, a man named Nicodemus who was a member of the Jewish ruling council. 2 He came to Jesus at night and said, “Rabbi, we know that you are a teacher who has come from God. For no one could perform the signs you are doing if God were not with him.” 3 Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.[a]” 4 “How can someone be born when they are old?” Nicodemus asked. “Surely they cannot enter a second time into their mother’s womb to be born!” 5 Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. 6 Flesh gives birth to flesh, but the Spirit[b] gives birth to spirit. 7 You should not be surprised at my saying, ‘You[c] must be born again.’ 8 The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.”[d]
