The Old Testament Law commanded the Israelites not to engage in interracial marriage (Deuteronomy 7:3-4[->0]). 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[->1]). 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.

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...
