Why the Orthodox Church Celebrated Easter a Week After the Catholic and Protestant Churches

Every year, the Christian world celebrates Easter, marking the resurrection of Jesus Christ from the dead. However, there is often confusion as to why the Orthodox Church celebrates Easter on a different date than the Catholic and Protestant Churches. This discrepancy can be attributed to the observance of different calendars and various historical events that led to the split between Eastern Orthodoxy and Western Christianity.

The primary reason for this discrepancy is the use of different calendars by the Orthodox Church and the Catholic and Protestant Churches. The Orthodox Church follows the Julian calendar, introduced by Julius Caesar in 45 BCE and slightly modified by Pope Gregory XIII in 1582, resulting in the Gregorian calendar widely used by the Catholic and Protestant Churches. The Gregorian calendar accounts for the extra leap day every four years, which the Julian calendar does not.

The Julian calendar used by the Orthodox Church has a fixed date for the vernal equinox on March 21st. According to the Julian calendar, Easter is celebrated on the first Sunday following the paschal full moon, which is the first full moon after the vernal equinox. This often results in a different date than that of the Gregorian calendar, which follows more precise astronomical calculations for determining the vernal equinox and the paschal full moon.

Moreover, the Orthodox Church determines the date of Easter based on the consensus of the Eastern Orthodox bishops. The bishops come together during the Council of Nicaea in 325 CE to establish a uniform method for calculating the date of Easter. This method aimed to prevent divisions among Christians caused by disagreements over the date of the most significant Christian holiday. As a result, the Orthodox Church celebrates Easter on the first Sunday after the Jewish Passover, ensuring a consistent date year after year.

Furthermore, historical events and the subsequent Great Schism in 1054 CE contributed to the different dates of Easter. The Great Schism led to the separation of the Eastern Orthodox Church from the Roman Catholic Church, resulting in distinct practices and traditions. The rift between eastern and western Christianity not only caused theological differences but also led to distinct liturgical observances, including the celebration of Easter.

The Orthodox Church, as an autonomous body, continued to follow the Julian calendar and adhere to its traditions, which included observing Easter according to its longstanding method. Meanwhile, the Catholic and Protestant Churches, influenced by the Gregorian calendar reforms, adopted the new calculations for the vernal equinox, paschal full moon, and subsequently, the celebration of Easter.

Despite the differing dates, the theological significance and spiritual essence of Easter remain unchanged in all Christian traditions. It is a time of deep reflection and joyous commemoration of Jesus Christ’s resurrection and triumph over death. The discrepancies in the dates serve as a reminder of the rich diversity within Christianity, as well as an opportunity for Christians to learn from and appreciate each other’s traditions.

In conclusion, the Orthodox Church celebrates Easter on a different date than the Catholic and Protestant Churches due to the use of the Julian calendar, the consensus of Eastern Orthodox bishops, and historical events, including the Great Schism. The observance of Easter represents the profound belief in the resurrection of Jesus Christ, regardless of the date on which it is celebrated. As Christians around the world unite in faith, the diversity represented by the different Easter dates serves as a testament to the strength and beauty of the worldwide Christian community.
