Beginning on the evening of Palm Sunday and continuing through the evening of Holy Tuesday, the Orthodox Church observes a special service known as the Service of the Bridegroom. Each evening service is the Matins or Orthros service of the following day (e.g. the service held on Sunday evening is the Orthros service for Holy Monday). The name of the service is from the figure of the Bridegroom in the parable of the Ten Virgins found in Matthew 25:1-13.
The first part of Holy Week presents us with an array of themes based chiefly on the last days of Jesus’ earthly life. The story of the Passion, as told and recorded by the Evangelists, is preceded by a series of incidents located in Jerusalem and a collection of parables, sayings and discourses centered on Jesus’ divine sonship, the kingdom of God, the Parousia, and Jesus’ castigation of the hypocrisy and dark motives of the religious leaders. The observances of the first three days of Great Week are rooted in these incidents and sayings. The three days constitute a single liturgical unit. They have the same cycle and system of daily prayer. The Scripture lessons, hymns, commemorations, and ceremonials that make up the festal elements in the respective services of the cycle highlight significant aspects of salvation history, by calling to mind the events that anticipated the Passion and by proclaiming the inevitability and significance of the Parousia.
The Orthros of each of these days is called the Service of the Bridegroom (Akolouthia tou Nimfiou). The name comes from the central figure in the well-known parable of the ten virgins (Matthew 25:1-13). The title Bridegroom suggests the intimacy of love. It is not without significance that the kingdom of God is compared to a bridal feast and a bridal chamber. The Christ of the Passion is the divine Bridegroom of the Church. The imagery connotes the final union of the Lover and the beloved. The title Bridegroom also suggests the Parousia. In the patristic tradition, the aforementioned parable is related to the Second Coming; and is associated with the need for spiritual vigilance and preparedness, by which we are enabled to keep the divine commandments and receive the blessings of the age to come. The troparion “Behold the Bridegroom comes in the middle of the night…”, which is sung at the beginning of the Orthros of Great Monday, Tuesday and Wednesday, relates the worshiping community to that essential expectation: watching and waiting for the Lord, who will come again to judge the living and the dead.
