VESPERAL LITURGY – Vespers with Divine Liturgy This service is prescribed only a few times each year. It opens with the blessing used at Divine Liturgy: “Blessed is the Kingdom . . .” The service continues similar to great vespers. There is no psalter reading, and there is an entrance with the gospel book. After the 3 Old Testament lessons, there is a small litany. The Divine Liturgy then follows, beginning from the Trisagion, followed by the prokeimenon, epistle, etc.
The days calling for its celebration in some or all years include: Dec. 24, Jan. 5, March 25, Holy and Great Thursday, Holy and Great Saturday.
