An unfortunate and unorthodox social and political theology has been on the rise recently, which teaches that the Bible advocates racial segregation and condemns interracial marriage. Nothing, of course, could be further from the truth. A great example of fellowship among those of different races takes place in Acts 13:1, which reads:
"Now there were at Antioch, in the church that was there, prophets and teachers: Barnabas, and Simeon who was called Νίγερ, and Lucius of Cyrene, and Manaen who had been brought up with Herod the tetrarch, and Saul"(Acts 13:1)
The word "Νίγερ" in this context refers to the blackness of his skin. John Gill not only interprets it in such a manner, but notes that the Ethiopic text translates the word as "black."
As Barnabas, and Simeon that was called Niger; the former of these was a Levite, and of the country of Cyprus, who sold his land and brought the money to the apostles; and who was first sent hither by the church at Jerusalem, upon hearing that many in this place believed, and turned to the Lord, Acts 4:36 but of the latter no mention is made elsewhere; by his first name he appears to be a Jew, who by the Romans was called Niger; very likely from the blackness of his complexion, for that word signifies "black": and so the Ethiopic version interprets it
Thus, the Apostles were not at all concerned with violating a biblical injunction against interracial fellowship (of which there is none). They were more than happy to fellowship with their non-white brothers in Christ.
