The Origin of Easter: From Passover to Modern Celebration

Every spring, Christians around the world celebrate Easter. Shops and homes are adorned with colorfully decorated eggs, rabbit figurines, and white lilies, as families gather together to enjoy egg hunts and festivities. But why is this sacred day commemorating the resurrection of Jesus Christ symbolized by eggs and rabbits, and why does the date change every year?

Easter is the most important holy day in Christianity, yet it is intricately woven with the Jewish Passover, the early Church’s date controversies, the schism between Eastern and Western churches, and Germanic folk traditions. From the cross and empty tomb in Jerusalem 2,000 years ago, through the heated debates at the Council of Nicaea in 325 CE, to today’s commercialized Easter celebrations, let’s trace the fascinating history of Easter.

The Origin of Easter: Deep Connections with Jewish Passover

Passover (Pesach): A Festival of Liberation

To understand Easter, we must first understand the Jewish Passover (Hebrew: Pesach).^[1] Passover commemorates the liberation of the ancient Israelites from slavery in Egypt.

According to the Book of Exodus in the Old Testament, when Pharaoh refused to let the Israelites go, God sent ten plagues upon Egypt.^[2] The final plague was the death of all firstborn sons in Egypt. At that time, the Israelites were commanded to slaughter a lamb and mark their doorposts with its blood, and the angel of death “passed over” the houses marked with blood, hence the name Passover.^[2]

Passover begins on the evening of the 14th day of Nisan (the first month in the Jewish calendar) and lasts for seven days.^[1] During this period, Jews eat unleavened bread (matzah) and conduct the Seder ceremony on the first night, reciting the story of the Exodus.^[1]

The Last Supper: A Passover Meal

According to the Gospel accounts, Jesus Christ’s crucifixion and resurrection occurred during Passover.^[3] Jesus’s famous “Last Supper” with his disciples was a Passover meal, during which Jesus symbolized the bread and wine as his body and blood, proclaiming a new covenant.^[3]

The Gospels record that Jesus died on the cross at the time when the Passover lamb was being slaughtered.^[3] Early Christians reinterpreted the meaning of Passover—liberation from Egyptian slavery—into the deeper dimension of liberation from sin and death.^[4]

Easter in the Early Church

During the early Church period, Christians commemorated Jesus’s resurrection in connection with Passover. However, there were regional differences regarding exactly when and how to celebrate it.^[5]

This controversy, known as the Quartodeciman controversy, intensified from the 2nd century.^[5] Christians in Asia Minor (modern-day Turkey) celebrated Easter on the 14th day of Nisan, the same day as the Jewish Passover. “Quartodeciman” means “Fourteenthers” in Latin.^[5]

In contrast, Rome and the Western Church commemorated the resurrection on the first Sunday after Passover.^[5] Sunday was the day Jesus rose from the dead and held symbolic significance as the Lord’s Day.

This controversy was not merely about dates but involved theological and identity issues. It embodied fundamental questions about how to define Christianity’s relationship with Judaism and whether to emphasize Christ’s passion or resurrection.

How the Date of Easter Was Determined

The Historic Decision of the Council of Nicaea (325 CE)

After Christianity was legalized by the Edict of Milan in 313 CE, Roman Emperor Constantine I convened the First Council of Nicaea in 325 CE to resolve divisions within the Church.^[6]

While the most important agenda was the Arian heresy, the issue of Easter’s date was also significantly addressed.^[6] The council established the following principles:

1. Easter should be calculated independently of the Jewish Passover^[6]
2. All Christians should celebrate Easter on the same day^[6]
3. Easter should be celebrated on the first Sunday after the first full moon following the spring equinox^[7]

This decision signified Christianity’s declaration as a religion distinctly separate from Judaism. It was also a measure emphasizing Church unity.^[6]

How Easter’s Date Is Calculated: Why Does It Change Every Year?

According to the Nicene principles, Easter’s date is calculated as follows:

“The first Sunday after the first full moon following the spring equinox (March 21)”^[7]

Due to this complex calculation method, Easter moves between March 22 and April 25 each year.^[7] This results from considering both the solar calendar (Gregorian calendar) and the lunar calendar (moon phases).

For example:

• Easter 2025: April 20
• Easter 2026: April 5
• Easter 2027: March 28

Thus, Easter is a movable feast, unlike Christmas which has a fixed date.^[7]

Differences Between Eastern and Western Churches

The Easter date controversy did not end here. In 1582, when Pope Gregory XIII introduced the Gregorian calendar, a new division arose.^[8]

The Eastern Orthodox Church decided to continue using the traditional Julian calendar.^[8] There is currently a 13-day difference between the two calendars, and they calculate the spring equinox differently.

As a result, the Western Church (Catholic and Protestant) and Eastern Orthodox Church often celebrate Easter on different dates.^[8] For example:

• 2024: Western Church March 31, Eastern Orthodox May 5
• 2025: Both Western Church and Eastern Orthodox April 20 (same day)

Occasionally the two churches’ Easters fall on the same day, but usually, there is a 1-5 week difference.^[8]

The Origin of Symbols Like Eggs

Easter Eggs: Lenten Fasting and the Symbol of Life

Colorfully decorated Easter eggs are today’s most famous Easter symbol. But what is the connection between Jesus’s resurrection and eggs?

The origin of Easter eggs is closely related to the Lenten fasting tradition.^[9] Lent is a 40-day period of penance and fasting before Easter. In medieval Christianity, not only meat but also eggs and dairy products were forbidden during Lent.^[9]

However, chickens continued laying eggs during Lent. People boiled eggs they couldn’t eat and stored them, resulting in an enormous accumulation by Easter.^[9] When the fast ended on Easter, people ate these eggs, offered them to churches, and gave them as gifts to neighbors.^[9]

The tradition of coloring eggs also developed during this period. Beyond mere decoration, eggs became symbols of new life.^[10] Just as new life emerges from a hard shell, it was believed to symbolize Jesus’s resurrection from the tomb.^[10]

In Eastern Europe, particularly Ukraine’s elaborately decorated eggs called pysanky, boast centuries of tradition.^[11] The technique of drawing intricate patterns with wax and dyeing them has been passed down through generations.^[11]

Easter Bunny: German Folk Tradition

The Easter Bunny is an even more puzzling symbol than eggs, as rabbits don’t appear anywhere in the Bible.

The Easter Bunny’s origin can be traced to German folk tradition.^[12] The 17th-century German literature first mentions “Oschter Haws” (Easter Hare), which laid colored eggs for good children.^[12]

Why rabbits? Rabbits were symbols of fertility and reproduction.^[12] Spring is the season of new life, and rabbits are known for birthing many offspring at once. This symbolism connected with themes of resurrection and new life.^[12]

When 18th-century German immigrants moved to Pennsylvania, USA, they brought the Easter Bunny tradition with them.^[12] Children made “nests” from hats or baskets on Easter Eve, and on Easter morning, they believed the Easter Bunny had laid colored eggs inside them.^[12]

In the 20th century, the Easter Bunny became commercialized as chocolate bunnies and plush toys, becoming today’s iconic Easter symbol.

Other Easter Symbols

Easter Lilies symbolize purity and the hope of resurrection.^[13] Lilies bloom into beautiful white flowers from underground bulbs, believed to symbolize the transition from death to resurrection.^[13]

Lambs represent both the Jewish Passover sacrifice and Jesus Christ, called the “Lamb of God.”^[14] In some cultures, lamb-shaped cakes or dishes are prepared for Easter.

The Cross and Empty Tomb are the most direct Christian symbols. Many churches use white cloth symbolizing the empty tomb on Easter morning with the proclamation “He is risen!”^[15]

Modern Easter: Secularization and Commercialization

Weakening of Religious Meaning

As Western society became increasingly secularized in the late 20th century, Easter’s religious meaning gradually weakened.^[16] For many people, Easter is perceived more as a spring festival, family gathering, and egg hunt day rather than Jesus’s resurrection.

Particularly, Easter egg hunts have become secular traditions enjoyed even by those without religious backgrounds.^[17] Children search for eggs hidden in gardens or parks (usually plastic eggs containing candy or small toys), which is considered purely recreational activity.^[17]

Commercialization: A Festival of Chocolate and Consumption

Easter is the second most commercialized religious holiday after Christmas.^[16] Worldwide, Easter-related product sales reach tens of billions of dollars.

The chocolate industry particularly utilizes Easter as a major sales season.^[18] Chocolate eggs, chocolate bunnies, and various Easter candies are mass-produced. In the United States, over 120 million chocolate bunnies are sold annually during the Easter season.^[18]

Cards, flowers, costumes, decorations, and other Easter-related products dominate the spring consumer market. In the 2020s USA, Easter-related spending exceeded $20 billion annually.^[16]

Diverse Easter Customs Around the World

Easter is celebrated uniquely in different parts of the world:

In Poland and Ukraine, there’s a tradition of making elaborately decorated eggs called pysanky. Wax-resist dyeing techniques create complex geometric patterns.^[11]

In Greece, people play a game of cracking red-dyed eggs against each other on Easter Eve.^[19] After midnight mass, fireworks are set off and people shout “Christos Anesti! (Christ is risen!)”^[19]

In Spain, elaborate processions and religious events unfold during Holy Week (Semana Santa). Penitents wearing pointed hoods marching through streets are iconic to Spanish Easter.^[20]

In the Philippines, some devout believers actually re-enact crucifixion on crosses.^[21] Though controversial, this tradition continues in some regions.^[21]

In the United States, the White House annually hosts the Easter Egg Roll event.^[17] Started in 1878, this tradition features children rolling eggs on the lawn.^[17]

In Australia, the bilby, a native marsupial, is sometimes used as an Easter symbol instead of rabbits.^[22] This is part of environmental conservation awareness efforts.^[22]

Conclusion: A Festival Where Sacred and Secular Coexist

Easter does not have a single origin. It is a cultural palimpsest intricately woven with Jewish Passover’s liberation theology, Christianity’s core doctrine of Christ’s resurrection, Lenten fasting customs, Germanic folk traditions, and modern commercialism.

When Jesus, observing Passover in Jerusalem 2,000 years ago, was crucified, his disciples fell into despair. But three days later, the empty tomb conveyed a message of new hope. The early Church formed around this mystery of resurrection, and in 325 CE, the Council of Nicaea decided that Christians worldwide would commemorate Easter on the same day.

In medieval times, eggs accumulated during Lenten fasting became Easter symbols, and rabbits, symbols of fertility from German folk tradition, emerged. Just as immigrants crossing the Atlantic transformed turnip lanterns into pumpkin jack-o’-lanterns, Easter traditions also transformed in new lands.

Today, Easter has a dual character. For devout Christians, it remains the most sacred day commemorating the core of faith—Jesus’s resurrection. Churches proclaim the joy of resurrection with “Alleluia!” praise after 40 days of Lenten penance and fasting.

Simultaneously, in secularized society, Easter has become a cultural festival celebrating spring’s arrival and a commercial opportunity selling chocolate and toys. Children enjoying egg hunts don’t know it’s related to Lenten fasting. People gifting chocolate bunnies are unaware of its origins as a fertility symbol.

Despite these changes, Easter still embodies universal themes of new beginnings, hope, and the triumph of life. Just as winter ends and spring flowers bloom, the message that death is not the end but a new beginning transcends time and culture.

Next Easter, when you see colorfully decorated eggs, remember they originated from Lenten fasting traditions; when you encounter an Easter bunny, recall it’s a fertility symbol from German folklore. And remember that behind the complex calculation of the first Sunday after the first full moon following the spring equinox were the heated theological debates of the 325 CE Council of Nicaea.

Easter is a unique festival where past and present, sacred and secular, East and West meet. And that is precisely why Easter has endured for 2,000 years and will continue to evolve and be celebrated.
