Diak, you seem to know lots about this stuff, so I direct this more toward you, but if anyone else knows, please answer. Thank you!
So St. Basil’s Divine Liturgy is the equivalent of a Latin Easter Vigil mass? (Both are vigils, right?)
What is the Anastasis Service?
What is Agape Vespers?
What is Jerusalem Vespers?
I think I need a complete breakdown of what happens Easter weekend for both Byzantine and Latin Rite. How it should be done and what can change.
To answer the question, Vespers and the Divine Liturgy of St. Basil does start the Paschal Vigil. The vigil ends with Paschal Matins and the Divine Liturgy, which are services of the day of Pascha itself and not the vigil. The “Anastasis service” is the service of the Resurrection, the Midnight Office, Matins and Divine Liturgy of the Resurrection. Agape Vespers is the Vespers of Pascha on Sunday evening, and I believe you meant “Jerusalem Matins” which is the Matins of Holy Saturday morning (often anticipated on Holy Friday evening).
First of all, it is not always easy to draw direct parallels and analogies between very different liturgical traditions. Pascha, being the “Feast of Feasts”, has its own unique liturgical order not seen at any other time.
Friday evening or Saturday morning parishes will celebrate the Jerusalem Matins. This is the service with the lamentations at the tomb, the service of celebrating the holy resting of our Lord on the Sabbath in his tomb. This is the proper service of Holy Saturday morning. (There is no Eucharist from Holy Thursday evening until the Vesperal Divine Liturgy of St. Basil with the rare exception of the coinciding celebration of the Annunciation).
In many parishes of the Slavic tradition the Jerusalem Matins is anticipated on Holy Friday evening. In some places another procession with the burial shroud (Plashchanytsia in Ukrainian or Epitaphios in Greek) takes place. Various readings or simply a single person guarding the tomb may occur in some parishes in the time between Jerusalem Matins and Holy Saturday Vespers and Divine Liturgy of St. Basil.
Holy Saturday afternoon or late morning (should start no earlier than 11 a.m. or so) the Paschal vigil begins with the Vespers and Divine Liturgy of St. Basil. Vespers begins the vigil throughout the ecclesiastical year, as has been pointed out above. So similarly Vespers and the Liturgy of St. Basil does begin the Paschal vigil. The high points of the Vespers and Liturgy of St. Basil are the reading of the 15 prophecies (if a parish takes all of them) with a festal singing of antiphons at the Song of Moses and the Song of the Three Holy Children. The first Gospel of the Resurrection is read at this service (which also coincides with the first regular Sunday Matins Gospel). This is also the only Liturgy of the year when “Alleluia” is not sung at the Gospel, but rather “Let God arise”.
The celebration of Pascha itself, the day of the feast, begins with a short service at the graveside (the Midnight Office). If the burial shroud from Holy Friday and Holy Saturday has not yet been placed on the altar it is placed here. Having come to midnight and thus the chronological time of day, the vigil proceeds into the services of the day itself of Pascha, the vigil realizing its fulfillment if you will. The Paschal Matins (Orthros in the Greek reckoning or Utrennya in Ukrainian) then usually begins immediately after the Midnight Office. Matins starts with a procession around the Church ending with the priest coming to the closed doors of the Church. In some traditions a Gospel passage of St. Mark is read, but in any case the priest sings Christ is Risen, the people respond, and then versicles of Psalm 67 are sung with the refrain “Christ is Risen”. The priest takes the hand cross, knocks on the door in the form of a cross, and the doors of the Church are opened to a fully lit Church with the bells tolling joyfully.
Paschal Matins is centered on the Paschal Canon of St. John of Damascus, which has the real heart of the catechetical content of Pascha, an essential part of the liturgical corpus of the Byzantine tradition. In some parishes Matins is celebrated at or near midnight; in some places the graveside service begins before dawn with Matins being sung as the sun arises (an especially moving liturgical experience if you ever get the chance). An excellent translation of the Paschal Canon with some good explanatory notes can be found at
anastasis.org.uk/paschal_canon_with_notes.htm
After Paschal Matins the Divine Liturgy of St. John Chrysostom usually begins immediately. Agape Vespers is the rather short (by Byzantine standards) and extremely joyous Paschal Vespers when a Gospel is read (the only time Vespers has an appointed Gospel without a Divine Liturgy) that is often read in several languages (as is sometimes the Gospel of the Divine Liturgy of Pascha itself).
I don’t profess to be an expert on the Latin practices, so I will leave it there. In many Latin dioceses I do know there are different prescriptions on what time the Vigil may or may not start.
So chronologically the order is: Jerusalem Matins; Vespers and Divine Liturgy of St. Basil; Midnight Service and Paschal Matins; Divine Liturgy of St. John Chrysostom; and Agape Vespers. Other services such as the Paschal Hours or a Paschal Moleben may also be celebrated after the Divine Liturgy of St. John Chrysostom.
