Why then does Christ call the bread his body and the cup his blood, or the new covenant in his blood, and Paul use the words, a participation in Christ’s body and blood?
John 6:51, 55 – I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world.”
For my flesh is real food and my blood is real drink.
1 Corinthians 10:16-17 – Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ? Because there is one loaf, we, who are many, are one body, for we all share the one loaf.
1 Corinthians 11:26 – For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes.
Romans 6:5-11 – For if we have been united with him in a death like his, we will certainly also be united with him in a resurrection like his. For we know that our old self was crucified with him so that the body ruled by sin might be done away with, that we should no longer be slaves to sin— because anyone who has died has been set free from sin.
Now if we died with Christ, we believe that we will also live with him. For we know that since Christ was raised from the dead, he cannot die again; death no longer has mastery over him. The death he died, he died to sin once for all; but the life he lives, he lives to God.
In the same way, count yourselves dead to sin but alive to God in Christ Jesus.
