No — interracial marriage is not a sin. Scripture does not prohibit interracial marriage anywhere. The prohibitions against marrying outside the Israelite community in the Old Testament were religious, not racial — they were about protecting Israel from idolatry, not preventing ethnic mixing. Moses married a Cushite (African) woman (Numbers 12:1). Ruth (a Moabite) is in the lineage of Jesus. The New Testament explicitly abolishes ethnic distinctions: Galatians 3:28 — 'There is neither Jew nor Gentile.' 90/100 Spiritually Safe.
Scripture does not prohibit interracial marriage anywhere. This is not a close call or a disputable matter — it is a clear case where the Bible's teaching has been misused to justify racial prejudice.
The Old Testament prohibitions against Israelites marrying Canaanites and other surrounding peoples (Deuteronomy 7:3-4, Ezra 9-10) were religious, not racial. The explicit reason is given immediately: "For they will turn your children away from following me to serve other gods" (Deuteronomy 7:4). The concern was theological — protecting Israel from the idolatry of pagan religious practice — not ethnic. An Israelite could marry a foreigner who worshipped the God of Israel without any prohibition.
Moses married a Cushite woman: Numbers 12:1 — "Miriam and Aaron began to talk against Moses because of his Cushite wife." Cush is the ancient name for the region south of Egypt — modern Ethiopia/Sudan. Moses's wife Zipporah (in Exodus) was a Midianite; this passage suggests a second wife, or that Zipporah herself is described here as Cushite. Critically: God's response to Miriam's objection is not to endorse her concern but to strike her with leprosy (Numbers 12:9-10). God's rebuke demonstrates the objection was wrong.
Ruth's marriage to Boaz: Ruth was a Moabite woman who married Boaz, an Israelite. She is specifically included in the genealogy of David — and of Jesus (Matthew 1:5). The book of Ruth is an extended celebration of a cross-ethnic marriage and its godly fruit.
Rahab in Jesus's genealogy: Rahab, a Canaanite prostitute from Jericho, married Salmon (an Israelite) and is in the genealogy of Jesus (Matthew 1:5).
The use of Genesis 9 (the "curse of Ham") to justify racial hierarchy and prohibitions on interracial marriage is one of the worst misuses of Scripture in American history. The "curse of Ham" is not a racial curse — it is a curse on Canaan (Ham's son), about specific geopolitical dynamics, and was used to justify slavery and racial segregation through a reading that serious biblical scholars across traditions have rejected as exegetically indefensible.
The New Testament is explicit: Galatians 3:28 — "There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus." Revelation 7:9 — the redeemed in heaven are "from every nation, tribe, people and language." Ethnic diversity is not a problem to be fixed but a feature of God's design.
