[This is the final part of “Covenant: How God Binds Himself to His People,” a 7-part series tracing covenant as the framework that holds the whole story of Scripture together. Read Part 6 here.]

The church in Corinth had a problem at the Lord’s Table. When they gathered for the meal, each person went ahead with his own supper, so that one went hungry and another got drunk (1 Corinthians 11:21). The Lord’s Supper had become one more place to sort people by what they could bring. Paul’s answer starts with a story. He takes them back to the night Jesus was betrayed and repeats what Jesus said over the cup: “This cup is the new covenant in my blood.”

If you have trusted Christ, you are already living inside everything this series has traced, and that table is where it all comes together. It is where Paul sends a squabbling church to find out who they are.

Where We Left Off

Over six posts we have followed one idea through the whole Bible. In short, 1) God binds Himself by promise, swearing alone while Abram sleeps; 2) He marks the promise with signs; 3) He keeps faith when His people break it; 4) He bears the covenant curse in Christ; and 5) He stands as mediator of a better covenant. Our last post, “A Better Mediator, A Better Covenant”, ended on Hebrews 8 and the promise that God would write His law on our hearts and remember our sins no more.

That leaves a practical question for the people who live inside this covenant: what does it look like on an ordinary Sunday, and on the Monday after? This post will not settle how the Lord’s Supper/Communion works. Faithful churches answer that differently, and our third post, “Signs and Seals: How God Marks His Covenant”, said as much. What every one of those traditions shares is what Jesus said the cup means. Here is the passage:

“For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, ‘This is my body, which is for you. Do this in remembrance of me.’ In the same way also he took the cup, after supper, saying, ‘This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.’ For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.” (1 Corinthians 11:23-26, ESV)

Why the Cup Is “the New Covenant in My Blood”

Jesus’ words carry two echoes from the Old Testament, and the men at that table would have caught both. The first is Sinai. When Moses sealed the first covenant, he took sacrificial blood, threw it on the people, and called it “the blood of the covenant” (Exodus 24:8). The second is Jeremiah. With Israel’s covenant-breaking already on the record, God promised a new covenant that would write His law on their hearts, make them His people, and forgive their iniquity (Jeremiah 31:31-34). That is the same passage Hebrews 8 quoted in our last post.

Now put the two together and listen to Jesus again. The cup is the new covenant, the one Jeremiah promised, and it is sealed in blood the way Sinai was, only this time the blood is His. Luke’s version adds a clause that is easy to skim past: “poured out for you” (Luke 22:20). Notice the “for you.” The bread is “for you” too, and the “you” in Paul’s Greek is plural (1 Corinthians 11:24). Translation? The gift is for the whole gathered church.

That is where the rest of the series lands. In our fifth post, “The Covenant Curse and the Curse-Bearer”, we saw Christ become the curse so that covenant-breakers could receive covenant blessing. The blood in the cup is what that cost, and “the new covenant in my blood” is the promise that the bill is paid.

Here is the heart-level reason this matters. Left to ourselves, we want to hold our own place at God’s table, which means we want a covenant whose terms we can meet. Sinai gave terms, and we broke them. Jesus hands us a cup and says the terms are met. Repentance, in the Bible’s sense, means changing your mind about who secured your standing and then trusting Him with it.

The Table of a Covenant Community

Jesus says it twice, once over the bread and once over the cup: “Do this in remembrance of me” (1 Corinthians 11:24-25). Remembrance of what, exactly? That the covenant is sealed, and by whom. “As often as you drink it” assumes a meal the church would keep coming back to. In our third post we saw that a covenant sign marks a promise already made. The Lord’s Supper is the sign the church gets to receive again and again, and each time we do, we proclaim the Lord’s death until He comes. The table looks back to the cross and ahead to His return, and in between it tells the church who we are.

Who we are, according to Paul, is a covenant community held together by one mediator. That was his point to Corinth. People who gathered at the same table were eating separate meals (1 Corinthians 11:21-22). Think of a wedding reception with place cards. Nobody auditions for a seat; the hosts write the names, and the guests find theirs. The wealthy cousin and the broke one are seated by the same hand. At Corinth, people were arguing over place cards the Host had already written. (Somebody always wants a table closer to the front.)

Paul does follow with a sober warning about eating and drinking “in an unworthy manner” (1 Corinthians 11:27), and plenty of believers read that and stay in their seats afraid. In context, the sin Paul has in view is the contempt the Corinthians showed one another at the meal. His remedy is to examine yourself and then eat (1 Corinthians 11:28), and he never tells anyone to stay away. How your own church guards the table is a matter for your pastors and elders. The text itself sends the Corinthians back to the table with a clearer head.

Living Inside the Story This Week

The covenant is a story whose main actor is God. He bound Himself to Abram while Abram slept, and He has been keeping faith with a people who could not keep it ever since. What is left for us to do? Receive, and then live like people who have.

Daily assurance lives here. On the day you fail, and you will, the covenant is still held by the One who made it, and the table is still set. I take up what a grace-driven life looks like from one day to the next in the second half of From Blessed to Transformed, if you want to follow that thread further.

Jeremiah 31 promised a people who would all know the Lord, from the least of them to the greatest (Jeremiah 31:34). Did you catch who is included? The least. A table that seats the least and the greatest side by side is a covenant community in action.

Application Points

• Come to the table as someone already named. Whether your church celebrates weekly, monthly, or a few times a year, the bread and cup are given to you. Take a quiet minute to confess what needs confessing, and then receive them as Jesus asked, “in remembrance of me,” knowing that the cup is “the new covenant in my blood,” poured out for you. Each time you do, you proclaim the Lord’s death until He comes.

• Remember your baptism on a bad day. However and whenever you were baptized, the sign marks a promise God made. When you have failed again, go back to what was promised over you.

• Read the Bible as covenant history. The next time you open a passage, ask 1) what promise is in view, 2) what sign marks it, 3) where someone breaks faith, and 4) where God keeps it. Many of Scripture’s stories answer at least a couple of those, and the cup is where they all land.

• Look down the table. The person you find hardest to sit beside in church is covered by the same blood you are. Greet them by name this week (someone came to mind just now).

Reflection Questions

• Now that you have traced covenant through Scripture, how does it change the way you see your place in the church, and at the table, this week?
• What do you quietly bring to the table to feel you deserve your seat, and what would it look like to come with nothing but your need?

We started this series with a word that had lost its edges and a rainbow over a flooded world, and we end at a table. The shape of the thing never changed along the way: God bound Himself by promise, marked it with signs, kept faith when His people did not, took the curse on Himself, and sent a mediator who is also the sacrifice. In “the new covenant in my blood,” Jesus gathers all of that into one cup and puts it in the hands of people who could never have earned it. The next time your church gathers at the table, take the bread and the cup as what you are, a covenant-breaker who belongs to a covenant-keeper. Then look at whoever is sitting beside you. The blood that covers them is the same blood that covers you.
