Easter

Easter is the principal feast of the ecclesiastical year. Leo I (Sermo xlvii in Exodum) calls it the greatest feast (festum festorum), and says that Christmas is celebrated only in preparation for Easter. It is the centre of the greater part of the ecclesiastical year. The order of Sundays from Septuagesima to the last Sunday after Pentecost, the feast of the Ascension, Pentecost, Corpus Christi, and all other movable feasts, from that of the Prayer of Jesus in the Garden (Tuesday after Septuagesima) to the feast of the Sacred Heart (Friday after the octave of Corpus Christi), depend upon the Easter date.

Easter is the principal feast of the ecclesiastical year. Leo I (Sermo xlvii in Exodum) calls it the greatest feast (festum festorum), and says that Christmas is celebrated only in preparation for Easter. It is the centre of the greater part of the ecclesiastical year. The order of Sundays from Septuagesima to the last Sunday after Pentecost, the feast of the Ascension, Pentecost, Corpus Christi, and all other movable feasts, from that of the Prayer of Jesus in the Garden (Tuesday after Septuagesima) to the feast of the Sacred Heart (Friday after the octave of Corpus Christi), depend upon the Easter date. Commemorating the slaying of the true Lamb of God and the Resurrection of Christ, the corner-stone upon which faith is built, it is also the oldest feast of the Christian Church, as old as Christianity, the connecting link between the Old and New Testaments. That the Apostolic Fathers do not mention it and that we first hear of it principally through the controversy of the Quartodecimans are purely accidental. The connection between the Jewish Passover and the Christian feast of Easter is real and ideal. Real, since Christ died on the first Jewish Easter Day; ideal, like the relation between type and reality, because Christ's death and Resurrection had its figures and types in the Old Law, particularly in the paschal lamb, which was eaten towards evening of the 14th of Nisan. In fact, the Jewish feast was taken over into the Christian Easter celebration; the liturgy (Exsultet) sings of the passing of Israel through the Red Sea, the paschal lamb, the column of fire, etc. Apart, however, from the Jewish feast, the Christians would have celebrated the anniversary of the death and the Resurrection of Christ. But for such a feast it was necessary to know the exact calendar date of Christ's death. To know this day was very simple for the Jews; it was the day after the 14th of the first month, the 15th of Nisan of their calendar. But in other countries of the vast Roman Empire there were other systems of chronology. The Romans from 45 B.C. had used the reformed Julian calendar; there were also the Egyptian and the Syro-Macedonian calendar. The foundation of the Jewish calendar was the lunar year of 354 days, whilst the other systems depended on the solar year. In consequence the first days of the Jewish months and years did not coincide with any fixed days of the Roman solar year. Every fourth year of the Jewish system had an intercalary month. Since this month was inserted, not according to some scientific method or some definite rule, but arbitrarily, by command of the Sanhedrin, a distant Jewish date can never with certainty be transposed into the corresponding Julian or Gregorian date (Ideler, Chronologie, I, 570 sq.). The connection between the Jewish and the Christian Pasch explains the movable character of this feast. Easter has no fixed date, like Christmas, because the 15th of Nisan of the Semitic calendar was shifting from date to date on the Julian calendar. Since Christ, the true Paschal Lamb, had been slain on the very day when the Jews, in celebration of their Passover, immolated the figurative lamb, the Jewish Christians in the Orient followed the Jewish method, and commemorated the death of Christ on the 15th of Nisan and His Resurrection on the 17th of Nisan, no matter on what day of the week they fell. For this observance they claimed the authority of St. John and St. Philip.
