A divided world needs a united church.  Paul wrote to a church composed of Jews and Gentiles from all over the ancient world and asked them to find their unity in Christ.  He used the analogy of a body to which different parts belong.  As I have mentioned before, we never just go to church.  We belong to the body of Christ and to each other.  It turns out that we are better together.  How will we do this?  With deep humility.
