Last night started the Lenten observance of the Liturgy of the Presanctified Gifts. This is one of the most ancient Liturgies in the Orthodox Church and I think one of the most beautiful. The Liturgy is attributed to St. Gregory the Dialogist who lived between AD 540-604 but historians do not agree on weather he wrote it himself or just wrote it down. Either way I am glad he did what he did. Here is a little explantion of the Liturgy from my friends at orthodoxwiki.
The service consists of Daily Vespers combined with additional prayers and communion. The communion bread has already been consecrated and intincted with the precious Blood and reserved at the previous Sunday’s Divine Liturgy. Unconsecrated wine is placed in the chalice. Local practice also varies as to whether or not this wine must be thought of as the Blood of Christ. The only practical effect of this variety is that the celebrant who must consume all the undistributed communion at the end of the service might or might not partake of the chalice when he communes himself.The service is preceded by the reading of the Typical Psalms, and the Divine Liturgy’s opening blessing, Blessed is the Kingdom… is used at the start of the part of the service that resembles daily vespers. Psalm 103, Bless the Lord, O my soul is read. The Great Litany is then intoned and then Psalms 119–133 are read. Then the choir sings Lord, I have cried unto Thee with stichera. The priest makes an entrance with the censer. If the occasion is a feast, the entrance is with the Gospel Book and there is then an epistle and gospel reading for the feast day.The choir sings O Gladsome Light, and the first reading, from Genesis (or Exodus), is read with a prokeimenon. Then the priest intones Wisdom, let us attend. The Light of Christ enlightened all men, and those praying prostrate themselves. The second reading, from Proverbs (or Job) is read.In the second part of the service, the choir chants Let my prayer be directed as incense before Thee, after which the prayer of St. Ephraim is read. After a litany the choir sings Now the powers of Heaven with us invisibly do worship, and the presanctified Gifts are brought into the holy altar in a procession resembling the Great Entrance at a Divine Liturgy but in silence. There is no anaphora because the gifts are pre-consecrated.The prayer of St. Ephraim the Syrian is repeated, and the Litany of Petition is proclaimed. The choir sings the Lord’s Prayer, after which the priest intones: The Presanctified Holy Things are for the holy. The Holy Sacraments are brought out through the Royal Doors, and the faithful receive Holy Communion. After the Litany of Thanksgiving and the prayer before the Ambo (“Every good and perfect gift is from above…”), the believers venerate the Holy Cross.
