The harlot, Rahab, also of another nation, is included in the lineage of Christ as recorded in Matthew 1.Colossians makes it clear that from God's perspective all are one in Christ.We get so many questions about dating, relationships, girlfriends and boyfriends, physical intimacy, and the whole list of awkward sex questions.
The book of Ruth tells a delightful story of a foreigner who became part of the lineage of Christ.The process of meeting a spouse had very little to do with compatibility and personality traits, and everything to do with family lineage and economic status.Finding a mate functioned a lot more like a bartering system than dinner and a movie.An important Bible verse about understanding interracial marriage is 2 Corinthians : "Do not be unequally yoked with unbelievers." That last word, "unbelievers" is of key importance.A Christian should not marry a non-Christian no matter how kind and good they are. Deuteronomy 7:1-6 tells the Israelites to destroy all the inhabitants of the Canaan land and not to intermarry with them because they would "turn your sons away from following Me, that they may serve other gods." The same key concern of 2 Corinthians is again expressed here.
The Bible is clear that when both parties are believers (equally yoked), interracial marriage is not wrong.
