The giant of Old Princeton, B. B. Warfield, outspokenly condemned the racism and rigid segregation of American society of his day. His views were remarkably ahead of his time with regard to an understanding of the evil of racism and even somewhat prophetic with regard to the further evil that would result from it. His convictions were explicitly grounded in an understanding and faithful application of the unity of the human race in Adam and the unity and equal standing of believers in Christ. This brief essay surveys Warfield’s arguments within the context of his day.
