Living in a non-Orthodox country
we Orthodox are frequently asked why we celebrate Eastern on a different date
in regards to the Western Christians. This also creates issues in respect to
schools and work, when the faithful are unable to go to all or most of the
services during Holy Week because Eastern is either 2 or 5 weeks after ‘normal’
Easter. Nevertheless, the issue relies on the complicated nature of calendars
and the way with which astronomical data is used.
The dating of Easter, of the
death and resurrection of Jesus, has always presented variations within the
Church. Even within the Bible we observe two distinct traditions. In the first
instance the traditions of the three Synoptic Gospels, i.e. Matthew, Mark and
Luke, identify the Last Supper as being a Passover meal. Therefore, Christ was
crucified the day after Passover. In the second case, the Gospel of John states
that the crucifixion took place the same day as the Passover. Hence, these two
traditions led to the establishment of two distinct practices. The first
opinion established the celebration of Easter on a set date, despite the day,
whilst the second one fixed it on the Sunday after Passover. Nevertheless, by
the fourth century the latter practice prevailed, with differences within the Catholic
Church.
A decision had to be taken, not
only from one part of the Church, but by the whole Body of the Ecclesia. This
issue was addressed during the First Ecumenical Council at Nicaea (325 AD).
During this Synod it was decided that Easter is to be celebrated on the Sunday
that follows the first full moon after the vernal equinox, which is when spring
starts. If, on the other hand, the full moon falls on a Sunday, then Pascha is
celebrated the following Sunday. The day taken to be the invariable date of the
vernal equinox is March 21st.
Another factor, on which the
dating of Easter is based on, is the date of the Jewish Passover. Due to
certain historical changes within the Jewish world, Passover was calculated
differently, i.e. meaning that Passover in some years preceded the vernal
equinox. The two celebrations of both religions coincided; however, this
existed for a short period of time. In Canon 1 of Antioch (330 AD) and Canon 7
of the Holy Apostles (4th century AD) condemned the calculation of Easter
according to the Passover. However, the First Ecumenical Council endeavoured to
maintain the calculating of Passover according to Jesus’ lifetime.
Until the 6th century
variations on the calculation of Easter were still apparent. Nevertheless, a more
secure mode of calculating, based on astronomical date, was accepted by the
Catholic Church. This was an alternative to calculating Eastern by the
Passover, forming the so called “paschal cycles”. Each paschal cycle matched to
a number of years. According to the number of years in the cycle, the full moon
occurred on the same day of the year as at the start of the cycle, with of
course some exceptions. The more accurate the cycle, the less frequent were the
exceptions. In the East part of Christendom a 19 year cycle was eventually
adopted, whilst on the Western part an 84 year cycle. Therefore, due to this
difference, we observe that East and West celebrate Easter on different dates.
Another factor which contributed
towards the widening of this difference was the adoption, by the West, of the
Gregorian Calendar (1582), thus replacing the Julian Calendar. The Orthodox
Church bases the calculation of Easter on the Julian Calendar, the calendar
used by the ancient Church.
Could this change? Open minded
leaders will be able to answer this, theoretically but also practically. It has
been an issue, in regards to the on-going Ecumenical Dialogue. The celebration
of Easter on the same date within the whole Christian family, worldwide, would
be an important step within the Ecumenical Movement, showing a sense of love
and understanding. With patience all could happen in the future.
