Rev. Bosco Peters at the website Liturgy in New Zealand has been encouraging Christians of all persuasions to consider celebrating Easter not as a single day, nor as an octave (week long celebration, lasting for eight days), nor even up to Ascension Day (forty days) but to celebrate the joy of the Resurrection through Pentecost, fifty days after Easter.
On his web site, Rev. Bosco writes:
Renewal of worship has rediscovered the value and significance of the Easter Season. Easter is not just "Easter Day"; it is the fifty days from Easter Day until the Day of Pentecost. During this season, Sundays might be better named "of Easter" rather than "after Easter" ("The Third Sunday after Easter," for example, is better termed "The Fourth Sunday of Easter").
Easter, Ascension, and Pentecost do not form three seasons. The Easter season celebrates the three dimensions of the resurrection, ascension, and the sending of the Spirit. Ascension material is appropriately used as Ascension Day approaches. Pentecost material is appropriate from Ascension Day to the Day of Pentecost. Easter threads, of course, remain suitable up to and including the Day of Pentecost.
These fifty days, a seventh of the year, form our great "Sunday" of the year. "Alleluia! Christ is risen. He is risen indeed. Alleluia!" forms the greeting in every service during Eastertide. Similarly "Alleluia! Alleluia!" is added to the Dismissal and the people's response. (These are equivalent to the "Alleluia" added at the beginning and end of the Daily Services.) These help to give these celebrations a distinctive festal feel.
The Paschal Candle is lit at every service up to and including the Day of Pentecost. "Glory to God in the highest" may be used daily from Easter Day through the Day of Pentecost. Alternatively, some communities use it daily for the first week of Easter.
Daily, or on certain days, people might gather in church in the evening, to light the Paschal Candle and sing the (at least sixteen centuries old) "Hail gladdening Light" (Phos Hilaron] page 175) or another hymn. Thanksgiving for light may follow, incense may be used (Ps 141:2), and parts of Night Prayer, Evening Worship, or the Daily Services may be used. Such a Service of Light, appropriately simplified, can form a very attractive focus for family prayer or prayer in a house group.
A Vigil service on the eve of the Day of Pentecost could focus around such a Service of Light. The Day of Pentecost concludes the Easter Season. Pentecost is when we celebrate the sweeping of the Spirit of God over the darkness and over the face of the waters.
The Jewish Pentecost was a single feast day celebrating harvest and commemorating the covenant. In the early church, however, the Christian Pentecost was not merely the "fiftieth day," but the word "Pentecost" often referred to the whole period of fifty days which began on Easter Day. This stress is being recovered. Now once more Eastertide is the "Season of Pentecost." The Day of Pentecost concludes the Pentecost season, rather than beginning it.
Just as Sunday is the first and the eighth day, so the "great Sunday" of the fifty days of Eastertide/Pentecost begins with the day of the resurrection and continues through eight Sundays, an octave of Sundays, a "week of weeks." It has been suggested that the English expression "Whitsunday" derives from the French huit (eight), Pentecost being le huitième dimanche, the eighth Sunday of Easter.
In the Fourth Gospel, the risen Christ imparts the gift of the Spirit on the evening of Easter Day (John 20:19-23). The Spirit is the gift of the risen Christ. And so in the Easter Season, this "Pentecost Season," we listen to the farewell discourses, with their promise of the coming Advocate, as words to us from the risen Christ.
So let's consider celebrating Easter not as a single day but as fifty days. Isn't the Resurrection of our Lord important enough to celebrate for the fifty days between Easter and Pentecost? It certainly seems so to me.
