There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
Maybe my biggest disappointment with the church as I’ve seen it for the most part, with notable exceptions, is just how monochrome, or segregated most churches are on any given Sunday. It is understandable, yet sad at the same time, in my view. God’s grace covers us, and there’s a history behind it. And it’s not like churches who are white or black want to be segregated. There are different cultures involved, and people are at home in different places.
But the gospel is meant to bring together those who likely would never do so apart from it. What is true concerning Jews and Gentiles being reconciled to God as one body (Ephesians 2:11-22) is also true of all peoples, bringing for example Palestinians and Jews together through the cross, through Jesus’s death, along with blacks and whites, Protestants and Catholics, everyone. The reconciliation to God extends no less to each other through the good news in Jesus, and the Spirit who makes us one in him.
As a witness to the gospel, and the saving power it brings, we need to show the world how we can work through the barriers, whatever they may be. How our unity in God through Jesus by the Spirit in the love of God in Jesus supercedes all distinctions, breaks down all animosities and hostilities, through Christ’s death, and our repentance and faith, and brings the promised healing and shalom. This new world is now present through Christ in his body the church. As a witness to the world, and as part of the salvation we ourselves need, in and through Jesus.
