Unleavened Bread in Communion: What Scripture Says
Short answer: Scripture never commands believers to use unleavened bread at the Lord's Supper. Jesus instituted the Supper during the Feast of Unleavened Bread, so the bread on the table was almost certainly unleavened. That historical detail is real. But the New Testament nowhere turns it into a rule for the church, and the words Jesus spoke over the bread are not about flour but about himself. The point of the Supper is not what is missing from the loaf but who is present at the table. Paul's concern in 1 Corinthians 11:23-29 is remembrance and self-examination, not ingredients.
What happened on the night Jesus was betrayed
The Supper did not appear out of nowhere. 1 Corinthians 11:23-29 opens with Paul passing on what he received: the Lord Jesus, on the night in which he was betrayed, took bread. That night was Passover, and Passover had been roasted lamb, bitter herbs, and unleavened bread for more than a thousand years. Jesus sat down with the twelve apostles when the hour had come, as Luke 22:14-20 records, and the meal on that table was the ancient feast of Israel. Whatever else we say, the first Lord's Supper was eaten in a Passover setting with Passover food.
So the bread Jesus took and broke that evening was almost certainly unleavened. Leaven in the Old Testament was regularly associated with corruption and sin, and the feast required every trace of it to be removed from the house. This is not incidental detail. It is the soil in which the Supper first grew. To say the bread was probably unleavened is simply to read the calendar carefully. Jesus was fulfilling a feast, not inventing a ritual disconnected from Israel's story.
Yet notice how Jesus handles the moment. Luke tells us he took bread, gave thanks, broke it, and gave it to them with the words recorded in the Gospel accounts. Matthew 26:26-29 shows him giving the bread with the command to take and eat, saying that it is his body. Everything in that sentence turns on the person, not the loaf. The bread is the sign; Jesus is the substance. If we fixate on what was baked and miss who was speaking, we have reversed the emphasis of the passage itself.
This matters because the Supper is rooted in real history. It is not a vague spiritual exercise. On a specific night, in a specific week, a real man took real bread at a real table and told his friends to remember him. The specificity of the event should make us careful and grateful, not anxious about ingredients. What happened that night was unique, unrepeatable, and finished. Our observance looks back to it, not back to a recipe.
Unleavened bread and the Passover context
Exodus 12:14-20 establishes the feast and its bread. God told Israel that the day would be a memorial kept as a feast to Yahweh throughout their generations, an ordinance forever. The week that followed began and ended with a solemn assembly, and during those days no leaven was to be found in Israelite homes. This was not a minor dietary preference. It was covenant observance, the yearly rehearsal of a rescue. Jesus did not step into a random evening; he stepped into that commanded remembrance and gave it a new center.
The unleavened loaf became a picture of sincerity and truth for Paul. In 1 Corinthians 5:6-8 he asks, "Don't you know that a little yeast leavens the whole lump?" and then calls the church to keep the feast with the unleavened bread of sincerity and truth. He is not writing a bakery order. He is exposing a church that was boasting while tolerating gross sin, and he uses the Passover imagery to show how a small compromise spreads. The loaf on the table, in other words, is meant to teach us something about ourselves.
That context is why many churches today choose unleavened bread, often matzo, for the Supper. They are not claiming a divine command where none exists. They are saying that the sign fits the story. If the Supper was instituted at Passover, and if Paul draws on the feast to describe holiness, then a flat, unyeasted loaf can quietly preach. This is a reasonable, historically informed choice, and no one should be scolded for making it.
But a reasonable choice is not the same as a binding law. The New Testament never says, use unleavened bread or your communion is invalid. Where Scripture is silent, we should be slow to bind consciences. A church that uses ordinary bread and a church that uses matzo can both obey the Lord who said, take and eat. The unity of the table is not threatened by the texture of the loaf.
What Jesus actually said over the bread
Look again at the words Matthew 26:26-29 preserves. Jesus gave thanks, broke the bread, gave it to the disciples, and said, "Take, eat; this is my body." Every verb is an action of self-giving. He did not say, notice the absence of yeast. He did not say, only bread baked without leaven may be used in remembrance of me. He gave himself, and the bread carried that gift to his friends. The emphasis falls entirely on the gift and the Giver.
Paul's account in 1 Corinthians 11:23-29 makes the same point from the other direction. He received from the Lord what he delivered to the Corinthians: the same night, the same bread, the same cup, the same proclamation of the Lord's death until he comes. His instructions are about remembering, proclaiming, and examining. If unleavened bread were essential, this is exactly where we would expect Paul to say so, because he is correcting a church that had turned the Supper into something else. He does not mention it.
What Paul does mention is the cup, the new covenant in Christ's blood, and the warning that comes with eating and drinking in an unworthy manner. The seriousness of the Supper is real, and it is not located in the ingredients. It is located in the body and blood of the Lord, and in the heart of the one who comes to the table. A person can eat matzo with a proud, divisive spirit and dishonor Christ. A person can eat ordinary bread with repentance and faith and honor him.
So the question to ask is not, is the bread leavened or unleavened, but, am I eating with the faith the Supper demands? The Lord's words are personal and searching. They invite us to take and eat, not to inspect and argue. Where a church has made a thoughtful choice, we can receive it with thanks. Where believers differ on the loaf, the table is still one table because the Lord is one Lord.
Leaven as a picture of sin and its spread
Paul's use of leaven in 1 Corinthians 5:6-8 is one of the clearest interpretive keys we have. He tells the church that a little yeast leavens the whole lump, then applies the image to boasting and to tolerating sin in the congregation. The point is not that yeast is evil in itself. The point is that small, accepted corruption quietly works through everything. That is how sin operates in a church, in a family, in a single heart. The image is moral, not culinary.
This is why the unleavened bread of the Passover carried such freight for Israel. Removing leaven from the house was a physical picture of removing sin from the life of the covenant people. The house had to be searched, swept, and made clean. Nothing was to be left hidden in a corner. Paul takes that familiar image and says, be what your bread says. Clean out the old leaven, because Christ, our Passover, has been sacrificed. The picture reaches its fulfillment in him.
If we are not careful, we can turn that imagery into a new law. Some believers have reasoned that since leaven symbolizes sin, using any leavened bread at the Supper must be sinful. The logic sounds tight, but it presses a symbol into a statute. Paul's command is to cleanse the church from sin, not to regulate the bread. The symbol is meant to drive us to holiness, not to add a burden the apostles never laid on anyone.
The right use of the image is self-examination. When we come to the table, we can ask where the leaven of pride, resentment, or secret sin has been quietly spreading. The Supper is not a place to hide such things. It is a place to bring them to the one who was broken for us. The imagery of the feast should make us more honest, not more fussy about what the loaf is made of.
Examining yourself and the unity of the table
1 Corinthians 11:23-29 was written to a divided, careless church. Some were eating their own supper while others went hungry, and the gathering that should have proclaimed the Lord's death had become a gathering that shamed the poor. Paul's correction is not about flour. It is about reverence, love, and discernment. He tells them to examine themselves, to recognize the body, and to take seriously what the bread and cup declare. Those are the issues the passage actually raises.
This is why dividing over the loaf is so tragic. Self-examination can become an obsession with details while ignoring the log of pride in our own eye. I have watched believers question one another's salvation over a cracker. The Supper is meant to display the unity of Christ's people, not to shatter it. If we battle over a symbol while treating one another with contempt, we have repeated the very sin Paul was confronting in Corinth.
At the same time, honesty requires us to acknowledge that faithful Christians disagree here. Many traditions use unleavened bread because of the Passover setting and the maturity of the imagery. Other traditions use ordinary bread because they see the Supper as a new covenant meal with few ceremonial requirements. Both are trying to honor Scripture. Neither has a command that the other is violating. We should speak with conviction where Scripture speaks, and with humility where it does not.
What unites us is not a baking method but a crucified Lord. The bread, whatever its form, points to a body given for us. The cup points to a covenant sealed in blood. When we come with faith and repentance, we proclaim his death until he comes. That is the center of the Supper, and it is enough for a divided church to come together around.
Christ our Passover and the bread of sincerity
The deepest answer to the question is a person. In 1 Corinthians 5:6-8 Paul identifies Christ as our Passover, sacrificed for us. That means the ancient feast has reached its goal. The lamb, the blood, the unleavened bread, and the urgent departure from Egypt all pointed forward to him. The Supper we keep now looks back to the cross and forward to the coming kingdom. The bread we use is a witness to that finished work, not an addition to it.
So the bread of the Supper should be received as the bread of sincerity and truth. That is not a description of the loaf; it is a description of the life we bring to it. We come without the leaven of malice and wickedness, as Paul puts it, because we have been cleansed by the sacrifice of Christ. The Supper is a family meal for forgiven people, and it calls us to live in the forgiveness we celebrate. The plate and the cup are means of grace precisely because they fix our eyes on him.
That means a church may choose unleavened bread out of love for the story, and a church may choose leavened bread out of love for simplicity. Neither choice saves anyone, and neither damps the power of the ordinance. The power is in the Lord who instituted it, not in the elements themselves. We should be suspicious of any teaching that makes the Supper depend on what we bring, whether the bread or the worthiness, rather than on what Christ has done.
When you next take the bread, whether it is crisp and flat or soft and thick, hear the words afresh: take, eat. The bread is given to you, and the one who gave it is not far off. Then look around at the others at the table. They are your family in him, and the meal is meant to bind you together. Unleavened or not, the Supper is his, and he is faithful.
Biblical fidelity check
What the passage does establish is clear. On the night he was betrayed, Jesus took bread, gave thanks, broke it, and gave it to his disciples with the command to take and eat, identifying it with his body. He did this in a Passover setting, in which the bread was almost certainly unleavened. Paul received and passed on this tradition, and he calls the church to remember, to proclaim the Lord's death until he comes, and to examine itself. The Supper is serious because of whose body it declares, not because of what the loaf contains.
What the passage does not establish is a requirement about leaven. There is no command in the New Testament to use unleavened bread, and no command forbidding leavened bread. The common misreading is that because leaven pictures sin in 1 Corinthians 5:6-8, using leavened bread at the Supper must itself be sinful. The error lies in treating an illustration as legislation. Paul used leaven to call a church to holiness, not to set a baking standard for worship. When a symbol is made into a law, consciences are bound where God has left them free.

Frequently asked questions
Was the bread at the first Lord's Supper unleavened?
Almost certainly, because the Supper was instituted during the Feast of Unleavened Bread, and no leaven was permitted in Israelite homes that week. Jesus sat down with the twelve apostles for that meal, and the bread on the table was Passover bread. So the historical answer is yes. But the New Testament does not draw a command from that fact, and it never tells the church to use unleavened bread when it gathers to remember him.
Must churches use unleavened bread for communion today?
No. Scripture contains no such command, and no verse forbids leavened bread either. Many churches choose unleavened bread because it fits the Passover setting and Paul's imagery, and that is a good and thoughtful decision. Other churches use ordinary bread, seeing the Supper as a simple covenant meal. Both can honor Christ. Where God has not spoken, believers should not bind one another's consciences.
Does the type of bread affect the meaning of the Lord's Supper?
It does not change the meaning, which is Christ's body given for his people and his blood poured out in the new covenant. The bread is a sign that points to him, and the power of the Supper rests on him, not on the loaf. The bread can illustrate the story, but it cannot add to the finished work of the cross. The important thing is to come with faith, repentance, and love for the body of Christ.
