Passover and the Feast of Unleavened Bread: What Every Christian Should Understand
Medically reviewed by Dr. Glenn Charles
Most Christians know the word "Passover" from the Last Supper and assume it refers to a single meal on a single night. Scripture actually describes two connected but distinct observances — Passover itself, a one-night event, and the Feast of Unleavened Bread, a seven-day observance that followed it. Understanding both, and how the New Testament reinterprets them, changes how you read half of the Gospels' final chapters.
Passover: The Night of the Lamb
The instructions in Exodus 12 are specific and were meant to be remembered exactly. Each household was to select a lamb without defect, kill it at twilight, and put its blood on the doorframes of the house. That night, the destroyer would pass through Egypt and strike every firstborn — but pass over any house marked by the blood (Exodus 12:12–13).
This was not a symbolic gesture in the moment. It was substitutionary: a lamb died so that a household's firstborn would not. The meal that followed — roasted lamb, bitter herbs, unleavened bread, eaten in traveling clothes with sandals on and staff in hand (Exodus 12:11) — was structured around urgency. Israel was to eat as people ready to leave immediately, because they were.
God commanded Israel to keep this as a permanent ordinance: "This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the Lord" (Exodus 12:14). The Passover meal became the central act of remembrance for the exodus itself — not just a rescue from slavery, but a rescue purchased by a substitute's blood.
The Feast of Unleavened Bread: Seven Days Without Yeast
Immediately following Passover, Israel was commanded to eat bread made without yeast for seven days: "On the first day remove the yeast from your houses, for whoever eats anything with yeast in it from the first day through the seventh must be cut off from Israel" (Exodus 12:15).
The reason given is practical and historical: Israel left Egypt in such haste that there was no time for bread to rise (Exodus 12:34, 39). The unleavened bread — matzah — became a physical reminder of how quickly and decisively God had acted. There was no leisure in the exodus. It happened in a single night, and the bread eaten in the days after preserved that memory in the most ordinary part of daily life: what was on the table.
By the Second Temple period, Passover and the Feast of Unleavened Bread were commonly spoken of as a single seven-to-eight-day festival, which is why the Gospels sometimes use the terms interchangeably (Luke 22:1 calls it "the Feast of Unleavened Bread, called the Passover"). Historically and textually, though, they are two distinct commands given in the same chapter of Exodus, joined by proximity and shared meaning rather than being one event.

What the Feast Meant Beyond Egypt
The absence of yeast carried a moral dimension beyond the historical memory. Yeast (leaven) works invisibly, spreads through the whole batch of dough, and was a natural image for something that corrupts from within. Paul draws directly on this when addressing sin tolerated within the Corinthian church: "Don't you know that a little yeast leavens the whole batch of dough? Get rid of the old yeast, so that you may be a new unleavened batch — as you really are" (1 Corinthians 5:6–7).
This is the move the New Testament consistently makes with the Feast of Unleavened Bread: not abandoning its meaning, but relocating it. The absence of yeast was never only about bread. It was about a people set apart, cleansed, ready to move at God's command — an image the church is now called to embody morally rather than through dietary observance.
Christ as the Fulfillment: Why the New Testament Reinterprets Both
The Last Supper was almost certainly a Passover meal (Matthew 26:17–19, Mark 14:12–16, Luke 22:7–15) — which is why Jesus' words over the bread and the cup carry so much weight. He took the elements of an ancient rescue meal and identified them with his own body and blood, being given "for you" (Luke 22:19–20). He was not replacing the Passover with an unrelated new ritual. He was declaring himself its true referent.
Paul makes this explicit: "For Christ, our Passover lamb, has been sacrificed" (1 Corinthians 5:7). The logic of Exodus 12 — a spotless substitute dies so that the household under its blood is spared judgment — is not abandoned in the New Testament. It is fulfilled. Jesus is the lamb without defect (1 Peter 1:19). His blood marks those who trust him, and judgment passes over them, not because they deserve it, but because a substitute has already borne it.
The Feast of Unleavened Bread receives the same treatment. Paul's instruction to "celebrate the festival, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth" (1 Corinthians 5:8) treats the feast as an ongoing moral pattern rather than a calendar obligation — purging what corrupts, living as people set apart, because the true Passover lamb has already been sacrificed.

Do Christians Need to Observe Passover Today?
This question comes up often, and Scripture gives a clear answer through Paul's broader teaching on the Old Testament calendar of feasts: "Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. These are a shadow of the things that were to come; the reality, however, is found in Christ" (Colossians 2:16–17).
Passover and the Feast of Unleavened Bread were shadows pointing toward a reality that has now arrived. They are not binding on Christians as a matter of law. At the same time, nothing in Scripture prohibits a Christian household from observing a Passover Seder meal thoughtfully, as a teaching tool that makes the Old Testament's typology vivid — many churches and families do this well, explicitly reading it through the lens of Christ's fulfillment rather than as a return to Mosaic obligation. The freedom Paul describes cuts both ways: free to observe it as instruction, free to not observe it at all, bound only to the reality both observances point toward.

Frequently Asked Questions
Are Passover and the Feast of Unleavened Bread the same thing?
Not originally. Exodus 12 describes Passover as a single-night meal (the 14th of Nisan) and the Feast of Unleavened Bread as the seven days that followed (the 15th through 21st). By the first century, Jewish usage often referred to the combined period as one festival, which is why the Gospels sometimes use the terms interchangeably.
Why couldn't Israel eat yeast during the feast?
Practically, because they left Egypt too quickly for bread to rise (Exodus 12:34, 39). Theologically, yeast became an image of something that spreads and corrupts — Paul later uses this picture to describe how sin, if tolerated, works through a whole community (1 Corinthians 5:6).
Was the Last Supper actually a Passover meal?
The synoptic Gospels (Matthew, Mark, Luke) present it as a Passover meal, which is why Jesus' actions over the bread and cup are so significant — he is reinterpreting the central meal of Israel's redemption story around himself, not introducing a disconnected new practice.
Do Christians have to celebrate Passover?
No. Paul explicitly frees believers from being bound by Old Testament festival observance, calling these things "a shadow of the things that were to come," with the reality found in Christ (Colossians 2:16–17). Some Christians choose to observe a Passover Seder as a teaching tool; it is not a biblical requirement.
What does it mean that Jesus is "our Passover lamb"?
It means the substitutionary pattern of Exodus 12 — an unblemished lamb dying so that the household marked by its blood is spared judgment — finds its true fulfillment in Christ's death. Paul states this directly in 1 Corinthians 5:7, treating Jesus' sacrifice as the reality the Passover lamb had always pointed toward.
