"This Is My Body": Luther's Chalk Line at Marburg

In October 1529, Luther met Zwingli in Marburg to debate the Lord's Supper. The debate was close on many points, but on one issue Luther would not budge. With a piece of chalk, he wrote on the table in front of him: "Hoc est corpus meum" — "This is my body." And he covered it with a cloth. Throughout the debate, he kept lifting the cloth to reveal those words: This is my body. Luther was immovable because he believed Jesus's words were plain: "This IS my body." Not "This represents my body." Not "This reminds you of my body." This IS. Luther believed that taking Jesus at his word meant affirming that Christ's body and blood are truly present in the Lord's Supper — not in a way that destroys the bread and wine (transubstantiation), but in, with, and under the bread and wine. The formula "in, with, and under" is technically called "consubstantiation" by its critics — but Lutherans prefer "sacramental union." As the heat is in the iron and the iron in the heat, so Christ's body is in the bread and Christ's blood is in the cup. Both are real. Both are present. When you receive the bread, you receive His body. When you receive the cup, you receive His blood. Luther staked everything on this.
Matthew 26:26-28Mark 14:22-24Luther at Marburg (1529)

Luther's Chalk Line

The chalk line at Marburg was not stubbornness — it was conviction. Luther had staked the entire Reformation on taking the Scripture at its plain meaning. "By faith alone" was the plain meaning of Romans 3. "This is my body" was the plain meaning of the Words of Institution. To spiritualize one and not the other would be inconsistent. The chalk line was the cost of consistency. "Here I stand" at the Table as much as at Worms.

"For You": The Personal Gift of the Real Presence

Luther's favorite words about communion were not the philosophical formulas but the personal words: "given and shed for you." "For you." Not for humanity in the abstract. For you. The Real Presence, in Lutheran theology, is not a matter of abstract metaphysics. It is a matter of comfort and assurance. When you come to the table and receive the bread, you receive Christ's body — given for you. When you receive the cup, you receive His blood — shed for you. The physical reception of the physical element is God's personal delivery of the forgiveness of sins directly to you. Luther taught that anyone who comes to the table and says "I do not want His body and blood; I only want forgiveness" is asking for the gift while refusing the Giver. The body and blood are the vehicle through which forgiveness is delivered. They cannot be separated. When you receive the element, you receive the forgiveness. The Lord's Supper is the Giver giving, personally, tangibly, to you. Come to this table knowing that what you receive in the bread and cup is not a religious experience or a mental state or a symbolic gesture. It is Christ Himself, given — for you.

Close Communion: The Table of the Confessing Community

Lutheran churches, especially confessional Lutheran bodies (LCMS), practice close communion — only confirmed Lutheran members (or members of churches in altar-and-pulpit fellowship) are invited to receive. This practice is often misunderstood as inhospitality. It is the opposite: it is pastoral care. Paul warns of eating and drinking "without recognizing the body" — bringing judgment on oneself. If a person does not share the confessional position of this congregation on the Real Presence — if they believe the bread is only a symbol or that Christ's body and blood are not truly present — then receiving with this congregation is a declaration of unity that does not actually exist. It is a lie told with the body. Close communion is the invitation to pursue unity before table fellowship — to study together, to agree together, to come to confessional agreement before sharing the meal. The table is not the place where we explore our differences. It is the place where we celebrate our unity in Christ. Come into that unity, and the table is fully open to you.
1 Corinthians 11:28-291 Corinthians 10:17Romans 16:17

Applications

  • 1Receive the body and blood of Christ with confidence. "For you" means you. Take it personally.
  • 2Come to the table for forgiveness, not as a reward for righteousness. Luther taught that we come weak and leave strengthened — not vice versa.
  • 3Return to your catechism. What does the Small Catechism say about the Sacrament of the Altar? Review it this week.
  • 4If you are not confirmed in a Lutheran congregation, study with us. We would love to welcome you to this table in full confessional unity.

Prayer Suggestions

  • Lord Jesus, we take You at Your word: "This is my body." We receive it as such — with gratitude for the gift and for the Giver.
  • "For you." Let those words land today. For me. For this person to my left. For every soul at this table. Personally given. Personally received.
  • For those who come with doubts or struggles: the body and blood of Christ are for the forgiveness of sins. Come for forgiveness. Come to the Giver.
  • Hoc est corpus meum. This is Your body. We receive it in faith. Amen.

Movie Analogy

Luther (2003)

The film captures Luther's stubborn, costly insistence on what the text says. "Here I stand. I can do no other." The same stubbornness that drove him to nail the 95 Theses drove him to write "This is my body" in chalk on the table at Marburg. Both were acts of costly conviction: taking God at His word, regardless of the consequences. Lutheran communion theology is the chalk line: Christ said "This is my body." We take Him at His word.

Classic

"This is my body" — not "this represents my body." Christ is truly present in, with, and under the bread and wine. This is the Luther line, and it is the scriptural line.

Pastoral

"For you." Those are the most important words at the Lord's table. His body — for you. His blood — for you. Come knowing your name is in those words.

Edgy

Luther wrote "This is my body" in chalk and covered it with a cloth. Every time Zwingli argued, Luther lifted the cloth. This IS my body. Stop explaining it away. Take Jesus at His word.

Frequently Asked Questions

What is the Lutheran doctrine of "Real Presence" in communion?

Lutherans teach that Christ's body and blood are truly present "in, with, and under" the bread and wine in the Lord's Supper. This is not transubstantiation (the elements don't change) nor mere symbolism (Christ is not absent). When the words of institution are spoken over the elements, Christ's body and blood are truly present and truly received by those who eat and drink.

Why do confessional Lutheran churches practice close communion?

Close communion reflects the Lutheran concern that receiving communion without recognizing the body of Christ brings judgment (1 Corinthians 11:28-29). If a person doesn't share the Lutheran understanding of Real Presence, receiving at a Lutheran table is a declaration of unity that doesn't exist. Close communion is an invitation to pursue confessional unity before sharing the table.
