So in Christ Jesus you are all children of God through faith, for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
We in Christ all belong to the household and family of God. We’re one. That doesn’t mean distinctions no longer exist, though the seeds of abolishing slavery are clearly in the New Testament, in this passage, in the book of Philemon, etc.
The gospel destroys all division in the sense of people not being united. We are “in Christ” and therefore united as one in him. That seems so obvious, a truism even, except that it hasn’t always been played out that way. African slaves were baptized when they responded in faith to the gospel. Yet they remained slaves, as if the family status was somehow only spiritual. That flies in the face of the meaning of the gospel, the good news in Jesus. It’s essentially a family, household thing, full heirs of God’s promise in Christ, as the above passage points out. Likewise females who were often either considered inferior to males, or treated as such are equal in being heirs and members of the family.
We are bereft with deep divisions in the world today. And they only seem exacerbated as people live more deeply and advocate their own common unity, or community. It would be good if by common grace people from diverse backgrounds: racial, religious, whatever could find common ground so that they could live well together. But that kind of unity could never approach the unity that is in Christ. It is good and important in its place, but it’s certainly not a full unity.
The unity in Christ does not destroy the diversity present. Women are still women, men, men, cultures, ethnicity is not changed. And such diversity will be a challenge at times. We are one in Christ, in one household, of one family in him, the family of God. Yet living in that one family will require humility as we learn to grow together. And surely the diversity is used by the Spirit to help us grow up in Christ in ways we otherwise would not. We can see diversity as all gifts from God for the whole, similar to the thought in Ephesians 4. To help us toward full maturity in Christ. That same passage tells us that though we are united in Christ, we’re to make every effort to keep the unity of the Spirit in the bond of peace. So to live well within that unity, to not become divided is not automatic.
We have to let this unity have its full effect, and that is both passive and active. We receive all God gives us in Christ by the Spirit. And we contribute our part, in return. In love in the unity that binds us all together in and through Jesus.
