There is no scriptural tenets against inter-racial marriage, there is scriptural tenets against homosexual acts.
Then how on earth did all those bigots of yore manage to use the bible to justify anti miscegenation laws?
"Almighty God created the races white, black, yellow, malay and red, and he placed them on separate continents. And but for the interference with his arrangement there would be no cause for such marriages. The fact that he separated the races shows that he did not intend for the races to mix" ~ Judge Leon Brazile 1959 anti-miscegenation ruling.
"...moral or social equality between the different races...does not in fact exist, and never can. The God of nature made it otherwise, and no human law can produce it, and no human tribunal can enforce it. There are gradations and classes throughout the universe. From the tallest archangel in Heaven, down to the meanest reptile on earth, moral and social inequalities exist, and must continue to exist throughout all eternity." ~ 1869 Georgia Supreme Court Ruling
And how about this gem from
Bob Jones University?
God has separated people for His own purpose. He has erected barriers between the nations, not only land and sea barriers, but also ethnic, cultural, and language barriers. God has made people different one from another and intends those differences to remain.. Bob Jones University is opposed to intermarriage of the races because it breaks down the barriers God has established. It mixes that which God separated and intends to keep separate. Every effort in world history to bring the world together has demonstrated mans self-reliance and his unwillingness to remain as God ordains. The attempts at one-worldism have been to devise a system without God and have fostered the promotion of a unity designed to give the world strength so that God is not needed and can be overthrown.
Although there is no verse in the Bible that dogmatically says that races should not intermarry, the whole plan of God as He has dealt with the races down through the ages indicates that interracial marriage is not best for man. We do believe we see principles, not specific verses, to give us direction for the avoidance of it.
The people who built the Tower of Babel were seeking a man-glorifying unity which God has not ordained (Gen. 11:4-6). Much of the agitation for intermarriage among the races today is for the same reason. It is promoted by one-worlders, and we oppose it for the same reason that we oppose religious ecumenism, globalism, one-world economy, one-world police force, unisex, etc. When Jesus Christ returns to the earth, He will establish world unity, but until then, a divided earth seems to be His plan.
Let them marry to whom they think best; only to the family of the tribe of their father shall they marry. Num. 36:6.
Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. For they will turn away thy son from following Me, that they may serve other gods: so will the anger of the Lord be kindled against you, and destroy thee suddenly. Deut. 7:3,4.
