The morning service of the Church is called Matins. It opens with the reading of six morning psalms and the intoning of the Great Litany. After this, verses of Psalm 118 are sung:
God is the Lord and has revealed himself unto us.
Blessed is he who comes in the name of the Lord.
The Troparion is then sung and, if it be a monastery, various groups of psalms which differ each day are read. Once again there are hymns on the theme of the particular day. On major feast days, special praises and psalms are sung, which on the Lord’s Day sing of Christ’s resurrection from the dead. On major feasts and on Sundays, the Gospel is also read.
After the Gospel there is a long intercessory prayer followed by a set of hymns and readings called the Canon. These songs are based on the Old Testamental canticles and conclude with the song of Mary, the so-called Magnificat (Lk 1.46–55). The Great Doxology is chanted followed by the morning litanies. The troparion is also repeated once again before the congregation is dismissed to begin the activities of the day.
The Matins service of the Church unites the elements of morning psalmody and prayer with meditation on the Biblical canticles, the Gospel reading, and the particular theme of the day in the given verses and hymns. The themes of God’s revelation and light are also always central to the morning service of the Church. Sometimes, particularly in churches of the Russian tradition, the Matins and the Vespers services are combined to form a long vigil service. On special feast days, the blessing of bread, wheat, wine, and oil is added to the Vespers, even when it is served separately from Matins. The faithful partake of the blessed food and are anointed with the oil as a sign of God’s mercy and grace.
