Where if at all does the bible speak against interracial marriages…..
As far as I know, the Bible does not forbid interracial marriages. There was a time when God had a special relationship with the nation of Israel and He commanded them not to marry those from the idolatrous nations. They were to be separated from the influence of those who would lead them away from God. Duet. 7:16.
However, today, God accepts all people from all nations who would come to Him through Jesus. Acts 10:34-35, Gal. 3:26-29. Therefore, there is no restriction on marriage as to specific nationality.
However, we should be careful not to marry (if we have not already done so) those who would lead us away from God. 2 Cor. 6:14-7:1.
