The Bible says that marriage is an honorable institution ordained by God (Hebrews 13:4). God says that marriage is to be for a lifetime (Romans 7:1-6). Divorce was only allowed by God because of the hardness of two hearts (Matthew 19:1-9).

In the New Testament God says to christians not to be, "unequally yoked together with unbelievers... " (2 Corinthians 6:14). The principle has not changed. Those who are evil or unbelieving can have a detrimental effect on christians (1 Corinthians 15:33). The Bible also commands widows who remarry to do so "only in the Lord" for the very same reason (1 Corinthians 7:39). However, Paul also says to the church at Corinth that those already involved in mixed marriages are not to initiate divorce proceedings because their spouses are not christians (1 Corinthians 7:12-16). The spouse who is a christian may have a. positive influence on the unbelieving spouse through their godly behavior and example (1 Peter 3:1-2).

God is always more concerned with the inward person because he sees and knows the heart (1 Samuel 16:7; Hebrews 4:12-13). Therefore, when the Bible speaks against mixed marriage it is a warning because of spiritual concerns rather than outward concerns. In terms of the flesh God ordains mixed marriage: one woman to one man (Matthew 19:1-9). In terms of race or ethnic concerns God does not speak either in a supportive or in a condemning way.
