A few of my favorite verses that speak of the unity of all in the body of Christ:
Gal. 3:28 (ESV) – There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus.
Col. 3:11 – Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all.
As we can see in these verses, there remains no room for prejudice, which is born out of ignorance and stereotyping, or “assigning traits to people based on their membership in a social category” (McShane and Von Glinow, Organizational Behavior, 2008, p. 73). When people become unfairly stereotyped, it is relatively easy for the one doing the categorization to become prejudiced toward members of this or that particular group.
Through His Scripture, the Lord teaches us that “here” (Col. 3:11) in Christ, is where our true identity is to be found. All of those who remain outside of Christ (the last Adam) are to be considered part of the race of the first Adam (1 Cor. 15:22, 45). There can be no further qualifications or distinctions made other than this. To attempt to create further divisions within humanity is to travel into territory that is foreign to God’s teaching in the New Testament.
The presence of racism in the body of Christ is one of the most abhorrent, destructive, and satanic ways of thinking imaginable, for in Christ there cannot exist any spirit of alienation or schism.
1Cor. 15:22, 45 – For as in Adam all die, so also in Christ shall all be made alive…. Thus it is written, “The first man Adam became a living being”; the last Adam became a life-giving spirit.
A sermon on the truth of Colossians 3:11 entitled “Christ is All” delivered by C.H. Spurgeon on August 20, 1871 can be found here. A small excerpt:
According to the connection, Christ is all by way of national distinction, subject for glorying, and ground for custom. Observe, “there is neither Greek nor Jew, circumcision nor uncircumcision, barbarian, Scythian, bond nor tree,” in the new creation, but “Christ is all, and in all.” In the new world there is no difference between Jew and Gentile; barbarian simplicity and Greek cultivation are as nothing. I suppose as long as we are in the flesh we shall set some store by our nationality, and like Paul shall somewhat glory that we were free born: but surely the less of this the better. Within the gates of the Christian church we are cosmopolitan, or rather we are citizens of the New Jerusalem only. As a man, I rejoice that I am an Englishman, but not with the same holy joy which fills me when I remember that I am a Christian. When I meet another man who fears God, I do not want him to think me an Englishman, nor do I desire to regard him as an American, a Frenchman, or a Dutchman; for we are no longer strangers and foreigners but fellow-citizens. If any man be a Christian and a foreigner after the flesh, he is yet in spirit ten thousand times more allied to me than if he were an Englishman and an unbeliever. Greatly is it to be deplored whenever the convulsions of nations drag Christian men into opposition to one another on the ground of politics. One part of the body of Christ cannot be at war with another. It is a shameful thing whenever we suffer our earthly nationality to dominate over our heavenly citizenship. Queen Victoria and President Grant are well enough in their places, but King Jesus is Lord of all; we are above all things subjects of his Imperial Highness the Prince of Peace. Nobody comes into the church as a Jew or a Gentile, nor does he remain there as a Greek or a Scythian, whatever he may have been before; when he becomes a Christian, Christ is all. Earthly distinctions of rank, if they still exist, as they must while we are in this world, are brought to a minimum within the church, they are almost obliterated, and what remains is sanctified to sacred ends.
