Jesuit Working On Common Date For Easter

The hope that all Christians will be able to celebrate Easter on the same day in the future was reaffirmed by an international ecumenical seminar organized by the Institute of Ecumenical Studies at the Ukrainian Catholic University in Lviv, 15 May.

The problem is just about as old as the church itself: As Christianity started to spread around the world, Christians came to differing results on when to commemorate Jesus Christ's death and resurrection, due to the different reports in the four gospels on these events.

Attempts to establish a common date for Easter began with the Council of Nicaea in the year 325. It established that the date of Easter would be the first Sunday after the full moon following the vernal equinox. However, it did not fix the methods to be used to calculate the timing of the full moon or the vernal equinox.

Nowadays the Orthodox churches use the 21 March of the Julian calendar as the date of the equinox, while the churches of the Western tradition – that is the Protestant and Catholic churches – base their calculations on the Gregorian calendar.

The resulting gap between the two Easter dates can be as much as five weeks. All participants at the seminar in Lviv, which included Orthodox, Roman Catholic and Protestant theologians from a variety of European countries, endorsed a compromise proposed at a World Council of Churches (WCC) consultation in Aleppo, Syria, in 1997.

The proposal was to keep the Nicaea rule but calculate the equinox and full moon using the accurate astronomical data available today, rather than those used many years ago.

Other speakers at the ecumenical seminar were Rev. Dr Dagmar Heller, professor at the Ecumenical Institute Bossey and executive secretary of the WCC Faith and Order Commission, Jesuit Father Milan Zust, an official of the Pontifical Council for Promoting Christian Unity, and Prof. Konstantin Sigov, director of Saint Clement Centre in Kiev, Ukraine.
