The Easter Vigil, also known as the Paschal Vigil, the Great Vigil of Easter, or Holy Saturday at the Easter Vigil in the Holy Night of Easter, is a liturgy held in traditional Christian churches as the first official celebration of the Resurrection of Jesus. Historically, it is during this liturgy that people are baptized and that adult catechumens are received into full communion with the Church. It is held in the hours of darkness between sunset on Holy Saturday and sunrise on Easter Day – most commonly in the evening of Holy Saturday or midnight – and is the first celebration of Easter, days traditionally being considered to begin at sunset.

Among liturgical Western Christian churches including the Roman Catholic Church, the Lutheran Churches and the Anglican Communion, the Easter Vigil is the most important liturgy of public worship and Mass of the liturgical year, marked by the first use since the beginning of Lent of the exclamatory "Alleluia", a distinctive feature of the Easter season.

In the Moravian Church, the sunrise service starts before dawn on Easter Sunday. Congregations of the Reformed tradition and the Methodist tradition may observe the Easter Vigil or hold a sunrise service. In Eastern Orthodox churches, Oriental Orthodox churches, and other traditions of Eastern Christianity, the extremely festive ceremonies and Divine Liturgy which are celebrated during the Easter Vigil are unique to that night and are the most elaborate and important of the liturgical year.

Earliest known form

The original twelve Old Testament readings for the Easter Vigil survive in an ancient manuscript belonging to the Armenian Patriarchate of Jerusalem. The Armenian Easter Vigil also preserves what is believed to be the original length of the traditional gospel reading of the Easter Vigil, i.e., from the Last Supper account to the end of the Gospel according to Matthew. In the earliest Jerusalem usage the vigil began with Psalm 117 sung with the response, "This is the day which the Lord has made." Then followed twelve Old Testament readings, all but the last being followed by a prayer with kneeling. (1) Genesis 1:1–3:24 (the story of creation); (2) Genesis 22:1–18 (the binding of Isaac); (3) Exodus 12:1–24 (the Passover charter narrative); (4) Jonah 1:1–4:11 (the story of Jonah); (5) Exodus 14:24–15:21 (crossing of the Red Sea); (6) Isaiah 60:1–13 (the promise to Jerusalem); (7) Job 38:2–28 (the Lord's answer to Job); (8) 2 Kings 2:1–22 (the assumption of Elijah); (9) Jeremiah 31:31–34 (the New Covenant); (10) Joshua 1:1–9 (entry into the Promised Land); (11) Ezekiel 37:1–14 (the valley of dry bones); (12) Daniel 3:1–29 (the story of the three youths).The twelfth reading leads into the Song of the Three Children and is not followed by a prayer with kneeling, but is immediately followed by the prokeimenon of the Eucharistic liturgy. Thomas Talley stresses the importance of this series of reading as representing the oldest known series and the one evidently having the very greatest influence on the development of all subsequent series of readings.Thomas J. Talley, The Origins of the Liturgical Year, New York: Pueblo Publishing Company, Inc., 1986, pp.48-49.

According to Byzantine historian Andrew Ekonomou, the Easter Vespers was unknown in Rome prior to its introduction in the mid-7th century, and solemnization by Pope Vitalian during the period when Rome was part of the Byzantine Empire. The Paschal vespers was long celebrated in Constantinople prior to this and the liturgy itself has details that appear eastern in origin.Andrew J. Ekonomou. Byzantine Rome and the Greek Popes.

Western Christian Churches

Catholic Churches

The Roman Missal states: "Of this night’s Vigil, which is the greatest and most noble of all solemnities, there is to be only one celebration in each church. It is arranged, moreover, in such a way that after the Lucernarium and the "Exsultet", The Easter Proclamation (which constitutes the first part of this Vigil), Holy Church meditates on the wonders the Lord God has done for his people from the beginning, trusting in his word and promise (the second part, that is, the Liturgy of the Word) until, as day approaches, with new members reborn in Baptism (the third part), the Church is called to the table the Lord has prepared for his people, the memorial of his Death and Resurrection until he comes again (the fourth part)."Roman Missal, The Easter Vigil in the Holy Night, 2

In the Roman Rite liturgy, the Easter Vigil consists of five parts:

The Lucernarium The Liturgy of the Word The rite of Baptism (Consecration of the water of baptism and bestowal of the sacrament of baptism if there are catechumens. Renewal of the baptismal vows by the whole congregation, followed by the Asperges) Liturgy of the Eucharist

The vigil begins between sunset on Holy Saturday and sunrise on Easter Sunday outside the church, where an Easter fire is kindled and the Paschal candle is blessed and then lit. This Paschal candle will be used throughout the season of Easter, remaining in the sanctuary of the church or near the lectern, and throughout the coming year at baptisms and funerals, reminding all that Christ is "light and life".

Once the candle has been lit, it is carried by a deacon through the nave of the church, itself in complete darkness, stopping three times to chant the acclamation 'Light of Christ' (Lumen Christi), to which the assembly responds 'Thanks be to God' or 'Deo Gratias'. As the candle proceeds through the church, the small candles held by those present are gradually lit from the Paschal candle. As this symbolic "Light of Christ" spreads, darkness is decreased.

The deacon, priest, or a cantor now chants the Exsultet (also called the "Easter Proclamation" or "Paschal Praeconium"), after which the people sit for the Liturgy of the Word.

Once the paschal candle has been placed on its stand in the sanctuary, the lights in the church are switched on and the congregation extinguish their candles (although in some churches, the custom is to continue the liturgy by candlelight or without any lights until the Gloria).

The Liturgy of the Word consists of seven readings from the Old Testament, although it is permitted to reduce this number for pastoral reasons to at least three, or for very pressing pastoral reasons two. The account of the Israelites' crossing of the Red Sea may never be omitted, since this event is at the centre of the Jewish Passover, of which Christians believe Christ's death and resurrection is the fulfillment. (1) Genesis 1:1–2:2 (the story of creation); (2) Genesis 22:1–18 (the binding of Isaac); (3) Exodus 14:15–15:1 (crossing of the Red Sea); (4) Isaiah 54:5–14; (5) Isaiah 55:1–11; (6) Baruch 3:9–15,32–4:4; (7) Ezekiel 36:16–17a, 18–28.Thomas Talley claims that the original readings of the Roman Paschal vigil were Genesis 1, Genesis 22, Exodus 14, Deuteronomy 31, Isaiah 4, Isaiah 54 and Baruch 3. Each reading is followed by a psalm or biblical canticle (i.e., 1. Psalm 104 or Psalm 33; 2. Psalm 16; 3. Exodus 15:1–18; 4. Psalm 30; 5. Isaiah 12:2–6; 6. Psalm 19; 7. when Baptism is celebrated: a combination of Psalm 42 and Psalm 43; 7. when Baptism is not celebrated: Isaiah 12:2–6 or Psalm 51) sung responsorially and followed by a prayer that relates what has been read in the Old Testament to the mystery of Christ. After these readings conclude, the altar candles are lit. The Gloria in excelsis Deo is sung for the first time since before Lent, with the exception of Holy Thursday or any solemnities or feasts that occurred during Lent.

The church bells and the organ, silent, since that point on Holy Thursday, are sounded again. It is customary in some churches to have no organ playing during Lent at all, except when accompanying hymns. In some regions, the statues, which have been covered during Passiontide, are unveiled at this time. After Gloria in Excelsis Deo, the collect is sung or recited by the celebrant. The reading from the Epistle to the Romans (Romans 6:3–11) is proclaimed, followed by the chanting of Psalm 118. The Alleluia is sung for the first time since before Lent and with special solemnity. The Gospel of the Resurrection (Matthew 28:1–10, Mark 16:1–8, or Luke 24:1–12 depending on the liturgical year) follows, along with a homily.

After the conclusion of the Liturgy of the Word, the water of the baptismal font is solemnly blessed, and any catechumens and candidates for full communion are initiated into the church by baptism or confirmation. After the celebration of these sacraments of initiation, the congregation renews their baptismal vows and receive the sprinkling of baptismal water. The prayer of the faithful, of whom the newly baptised are now part, follow.

After the prayers, the Liturgy of the Eucharist continues as usual. This is the first Mass of Easter Day. During the Eucharist, the newly baptized receive Holy Communion for the first time. According to the rubrics of the Roman Missal, the Eucharist should finish before dawn.

Lutheran Churches

The Easter Vigil, like the Christmas Vigil, remained a popular festive worship service in the Lutheran churches during and after the Reformation. It was often celebrated in the early morning hours of Easter Sunday. As in all Lutheran services of this period, vernacular language was used in combination with traditional liturgical texts in Latin, such as the Exsultet. Elements which were considered unbiblical and superstitious were eliminated, such as the blessing of the new fire, the consecration of the candles or of water.Mahrenholz, Christhard: Agende II für evangelisch-lutherische Kirchen und Gemeinden, Lutherisches Verlagshaus, Berlin 1960, pp. 304–306; Schmidt-Lauber, Hans-Christoph: Die Zukunft des Gottesdienstes, Calwer Verlag, Stuttgart, 1990, pp. 395–396Emphasis was placed on the scriptural readings, congregational singing and on the Easter sermon. In Wittenberg the Easter Gospel (Matthew 28. 1–10; 16–20) was sung in the German language in a tone similar to the tone of the Exsultet - a gospel tone only used for this worship service. The devastation caused by the Thirty Years' War led to a decline in worship culture in the Lutheran Churches in Germany. The rationalism of the 18th century also brought about a change in worship habits and customs. The liturgical movement that arose in the German Lutheran Churches after World War I rediscovered the Easter Vigil in its reformational form.

In an article from 1934 for the Liturgical Conference of Lower Saxony and for the Berneuchen Movement, Wilhelm Stählin appealed to fellow Lutherans for an Easter service on early Easter Sunday or on Holy Saturday night using elements from the Missal, the Orthodox tradition and from reformational service orders. An order for the Easter Vigil was published in 1936. Several Lutheran congregations in Hannover observed the Easter Vigil in 1937. Since then, the Easter Vigil has experienced a revival in many parishes throughout Germany.

This movement within the German Lutheran Churches contributed to a revival and revision of the Roman Catholic order for the Easter Vigil by Pope Pius XII in 1951. The "Agende II" for the Evangelical Lutheran Churches and Parishes in Germany from 1960 gave the "Osternacht", German for "Easter Vigil", a normative form. The most recent agenda for the Easter Vigil was published by the "Vereinigte Evangelisch-lutherische Kirche" in 2008.

The order for the Easter Vigil is comparable to the order of service used by American Lutherans. It is characterized by a number of Gregorian chants, medieval and reformational hymns which have been in use in German worship services for centuries.
