In the Roman Catholic Church, the Gospel lesson at Mass tells of the Anointing of Jesus at Bethany (John 12:1-9), which chronologically occurred before the Entry into Jerusalem described in John 12:12-19. Other readings used are Isaiah 42:1-7 and Psalm 27:1-3, 13-14.
Few Protestant churches have special services for Holy Monday. Those that do may follow the general pattern of the Roman Catholic observance.
In the Orthodox Church and those Eastern Catholic Churches that follow the Byzantine Rite, this day is referred to as Great and Holy Monday, or Great Monday. On this day the Church commemorates the withering of the fruitless fig tree (Matthew 21:18-22), a symbol of judgement that will befall those who do not bring forth the fruits of repentance. The hymns on this day also recall Joseph, the son of Jacob, whose innocent suffering at the hand of his brethren (Genesis 37), and false accusation (Genesis 39-40) are a type (foreshadowing) of the Passion of Christ.
The day begins liturgically with Vespers on Palm Sunday night, repeating some of the same stichera (hymns) from the Praises of the All Night Vigil the evening before. At Small Compline a Triode (Canon composed of three Odes), written by St. Andrew of Crete is chanted.
The Matins service for Monday through Wednesday of Holy Week is known as the Bridegroom Service or Bridegroom Prayer, because of their theme of Christ as the Bridegroom of the Church, a theme expressed in the troparion that is solemnly chanted near the beginning of the service. On these days, an icon of "Christ the Bridegroom" is placed on an analogion in the center of the temple, portraying Jesus wearing the purple robe of mockery and crowned with a crown of thorns (see Instruments of the Passion). The Matins Gospel read on this day is from the Gospel of Matthew 21:18-43). The canon at Matins has only three odes in it (a triode), and was composed by St. Cosmas of Maiuma.
The four Gospels are divided up and read in their entirety at the Little Hours (Third Hour, Sixth Hour and Ninth Hour) during the course of the first three days of Holy Week, halting at John 13:31. There are various methods of dividing the Gospels, but the following is the most common practice:
Holy and Great Monday
- Third Hour—The first half of Matthew
- Sixth Hour—The second half of Matthew
- Ninth Hour—The first half of Mark
At the Liturgy of the Presanctified Gifts, some of the stichera from the previous night's Matins (Lauds and the Aposticha) are repeated at Lord, I have cried (see Vespers). There are two Old Testament readings: Exodus 1:1-20 and Job 1:1-12. There is no Epistle reading, but there is a Gospel reading from Matthew 24:3-35.
