--Easter--

According to the New Testament, Christ was crucified on the eve of Passover and shortly afterward rose from the dead. In consequence, the Easter festival commemorated Christ's resurrection.

In time, a serious difference over the date of the Easter festival arose among Christians. Those of Jewish origin celebrated the resurrection immediately following the Passover festival, which, according to their Babylonian lunar calendar, fell on the evening of the full moon (the 14th day in the month of Nisan, the first month of the year); by their reckoning, Easter, from year to year, fell on different days of the week.

Christians of Gentile origin, however, wished to commemorate the resurrection on the first day of the week, Sunday; by their method, Easter occurred on the same day of the week, but from year to year it fell on different dates. An important historical result of the difference in reckoning the date of Easter was that the Christian churches in the East, which were closer to the birthplace of the new religion and in which old traditions were strong, observed Easter according to the date of the Passover festival. The churches of the West, descendants of Greco-Roman civilization, celebrated Easter on a Sunday.
