The Great Vigil of Easter
From the Book of Divine Worship - The Proper: First Part
Concerning the Vigil
The Great Vigil is the first service of Easter Day. It is celebrated at a convenient time between sunset on Holy Saturday and sunrise on Easter Morning.
The service normally consists of four parts:
It is customary for all the ordained ministers present, together with lay readers, singers, and other persons, to take active parts in the service.
The bishop, when present, is the chief celebrant, presides at Baptism and administers Confirmation, and normally preaches the sermon.
The priests who are present share among them the reading of the Collects which follow each Lesson, and assist at Baptism and the Eucharist. In the absence of a bishop, a priest presides at the service.
It is the prerogative of a deacon to carry the Paschal Candle to its place, and to chant the Exsultet. Deacons likewise assist at Baptism and the Eucharist according to their order.
Lay persons read the Lessons and the Epistle, and assist in other ways. A lay person may be assigned to chant the Exsultet. It is desirable that each Lesson be read by a different reader.
