When we drink from the cup that we ask God to bless, isn't that sharing in the blood of Christ? When we eat the bread that we break, isn't that sharing in the body of Christ?
Some of us are Jews, and others are Gentiles. Some of us are slaves, and others are free. But God's Spirit baptized each of us and made us part of the body of Christ. Now we each drink from that same Spirit.
We are telling you what we have seen and heard, so that you may share in this life with us. And we share in it with the Father and with his Son Jesus Christ.
