Great Vespers at a Vigil
Lord, I call: 3 resurrection + 3 triodion + 4 feast; glory: triodion; now: feast.
Entrance, prokeimenon of the day. Readings of the feast. Litany: Let us say ... etc. Vouchsafe. Let us complete our evening ...
Litya: the first 3 stichera of the feast, and 2 from the triodion (from the matins praises: O faithful, let us hate the boastful words of the Pharisee ... and: O Lord, you have condemned the Pharisee who justified himself ...) ; glory: triodion (from the litya); now: feast.
Aposticha: resurrection, with their verses; glory: triodion; now: feast.
Troparia: Feast (3x)
(If vigil is not served: resurrection; glory and now: feast.)
The above order also applies if the Sunday of the Prodigal Son coincides with Feast of the Meeting of the Lord. At litya the order would be: the first 3 stichera of the feast, and 3 from the triodion (from the matins praises: I come before You, O Lord, with the cry ...; Like the Prodigal I have wasted ...; and O good Father, I have departed ...) ; glory: triodion (from the litya); now: feast.
