Debate Over the Date of Easter in Early Christianity

Determining when to celebrate the resurrection of Jesus sparked a major controversy in early Christianity, with two distinct positions: Eastern and Western. This dispute, known as the Paschal Controversy, wasn’t fully resolved until the 8th century.

In Asia Minor, Christians celebrated the crucifixion on the same date as the Jewish Passover, which was the 14th day of Nisan, the spring full moon (see Jewish calendar). Regardless of the day of the week, the resurrection was then celebrated two days later, on the 16th of Nisan.

In the West, however, Jesus’ resurrection was celebrated on a Sunday, the first day of the week, as that was the day he rose from the dead. As a result, Easter was always celebrated on the first Sunday after the 14th of Nisan.

Over time, more churches began to favor the Sunday observance, and those who supported observing the 14th day (called Quartodecimans) became a minority. In 325 AD, the Council of Nicaea decreed that Easter should be celebrated on the first Sunday after the first full moon following the spring equinox (March 21). Thus, Easter could fall on any Sunday between March 22 and April 25.

The Eastern Orthodox churches use a slightly different calculation based on the Julian calendar (which is 13 days behind the Gregorian calendar used by Western churches), so Orthodox Easter is usually celebrated on a different date than by Protestants and Roman Catholics.

Additionally, Orthodox tradition forbids celebrating Easter before or during Passover.

In the 20th century, there were several attempts to set a fixed date for Easter, with one suggestion being the Sunday after the second Saturday in April. Though such proposals gained support, none were implemented.

In the early 21st century, discussions among leaders of the Eastern Orthodox, Syriac Orthodox, Coptic, Anglican, and Roman Catholic churches revived interest in establishing a fixed date—but no official agreement has yet been reached.
