The Liturgy of the Hours & Why Catholics Pray It

The Liturgy of the Hours, also called the Divine Office or Opus Dei (Work of God), is the daily prayer of the Catholic Church. Rooted in Scripture and ancient Christian tradition, it sanctifies the day through prayer at specific times, marking the rhythm of daily life with worship. The purpose of the Divine Office is to sanctify the entire day by offering it to the glory of God. The word “office” means “service”; the Divine Office is the service in which we render continual praise and thanksgiving to our Creator.

The practice originates from Jewish prayer traditions, where priests from the line of Aaron offered a morning and evening sacrifice to God according to the Law. While they were in exile, without a Temple in which to make these offerings, the Jewish people prayed Psalms, hymns, and Scripture readings throughout their day. Once the Temple was rebuilt, they resumed their sacrifices but also continued praying in the mornings, evenings, and at the third, sixth, and ninth hours of the day.

Fast forward to the New Testament and we know that Jesus also prayed throughout the day, frequently rising early to do so. The Acts of the Apostles mentions that the disciples and first Christians continued praying at the third, sixth, and ninth hours of the day. Although they still went to the Temple to pray at these times, they no longer participated in the ritual sacrifices, as they now had the Eucharist (“the breaking of the bread”) as their new form of sacrifice to God.

The prayers vary according to the date, time of prayer, liturgical season, and saint of the day. The sequence of prayers in the Liturgy of the Hours is rooted in the Psalms. In the sixth century St. Benedict of Nursia, instructed his monks to pray all 150 Psalms within a week, establishing a disciplined rhythm of prayer that emphasized regular engagement with Scripture and integration of prayer into daily work. His influence led to the Divine Office becoming the central prayer of monastic life, which shaped Christian spirituality for centuries. 

A major revision came with the Second Vatican Council in the 1960s. The Church sought to encourage broader participation in the Divine Office by making it more practical for clergy, who are required to pray the Divine Office every day according to Canon law and for lay people alike. This led to a restructuring of the traditional monastic schedule, expanding the cycle from one week to four weeks, so that all 150 Psalms are now prayed over the course of a month. 

Many Christians partake in the Liturgy of the Hours because at its core, it is an act of praise to our Creator, joining the entire Church — on earth and in heaven — in unceasing worship. It fulfills St. Paul’s exhortation to “pray without ceasing”  (1 Thessalonians 5:16-18), providing a sacred rhythm that transforms each day into an ongoing conversation with God.

Through hymns, psalms, and readings, the Liturgy of the Hours marks time with meaning. Each Hour reflects the symbolism of the time of day, the liturgical season, or the feast being celebrated. Morning Prayer (Lauds), for example, welcomes the new day with praise and renewal, while Evening Prayer (Vespers) offers thanksgiving as the day draws to a close.

The Scripture readings and reflections from the Church Fathers and spiritual masters at certain Hours help reveal the deeper meanings of the mysteries we celebrate, help us understand the Psalms, and prepare our hearts for silent prayer. By engaging with God’s Word daily, we learn to see the world, our neighbors, and even ourselves as God sees us.

Whether we pray alone or in community, the Liturgy of the Hours transforms everyday life into a continual offering of praise, immersing us in the life of the Church and deepening our awareness of God’s presence throughout the day.

It is important to know that the name “Liturgy of the Hours” does not refer to the length of the prayers (they are not 60‑minute sessions), but to the fixed times of day at which they are prayed. In Christian tradition, especially in the Catholic Church, the “hours” are the canonical hours, which mark the divisions of the day into prayer periods and typically takes between 30 minutes to 2 hours daily, depending on which hours are prayed and the length of the psalms and readings chosen. So, even though the prayers are brief, they are called “hours” because they are scheduled at specific times of the day, continuing a long‑standing tradition of dividing the day into prayer periods.

The Liturgy of the Hours is organized around five main periods of prayer, each with its own spiritual focus and scriptural themes. Every Hour includes selections from the Psalms, a reading from Scripture or spiritual reflections, and other prayers that help sanctify the day. These prayers are not simply personal devotions but acts of worship uniting the Church in a continuous offering of praise to God.

The Major Hours (The Office of Readings, Morning Prayer, Evening Prayer) are the anchors of daily prayer. They are longer, richer offices that mark the heart of the day. (These are the Hours most Catholics pray).

The Office of Readings (Matins) is the longest Hour and is unique in that it can be prayed at any time of day. Originally a nighttime vigil prayer, it provides an extended period of meditation on Sacred Scripture and the writings of the Church Fathers and spiritual masters. The readings deepen our understanding of the mysteries of faith and help prepare our hearts for silent contemplation.

Morning Prayer (lauds) is one of the two most important (or “hinge”) Hours of the Divine Office. We pray it at the start of the day to sanctify the morning and recall the resurrection of Christ. The theme of Lauds is praise, reflecting the freshness of a new day and the renewed mercies of God. This Hour includes the Canticle of Zechariah (known as the Benedictus (Luke 1:68-79), a hymn of thanksgiving and prophecy, which acts as a meditative extension of the Scripture reading. Morning Prayer also includes intercessions that flow from the scriptural proclamation, offering prayers for the needs of the Church and the world. 

Evening Prayer (Vespers) is the second “hinge” Hour and is considered one of the most important prayers of the Church. We pray it as the day draws to a close, offering thanksgiving for the blessings we’ve received and reflecting on the work we’ve completed. Vespers is sometimes understood as a fulfillment of the evening sacrifice entrusted to the apostles at the Last Supper (Psalm 141:2).

This Hour includes the Canticle of Mary (Magnificat, Luke 1:46-55), Mary’s song of joy and humility. Like the Benedictus in Morning Prayer, the Magnificat serves as a meditative response to the Scripture reading, emphasizing God’s faithfulness and mercy. Evening Prayer also includes intercessions, presenting the needs of the Church and the world before God.

Minor Hours: (or little hours) Shorter prayers that sanctify different points of the day.

Daytime Prayer consists of three possible times: Midmorning (Terce), Midday (Sext) and Midafternoon (None). We may recite these prayers during breaks in work or private devotion to help us maintain awareness of God’s presence throughout the day. Although the specific Psalms vary, all three offices share a similar structure and remind us that every moment of the day belongs to God. 

Night Prayer (Compline) is the final prayer of the day, which we say before retiring, even if it is after midnight. It is a peaceful and reflective prayer, placing trust in God’s protection through the night. The Psalms chosen for Compline are full of confidence in the Lord, often expressing themes of surrender, security, and rest. This Hour concludes with a short hymn or Marian antiphon, such as the Salve Regina, entrusting the faithful into the care of the Blessed Mother. 

Early Church Fathers, such as St. Cyprian, interpreted the Ninth Hour (None-3 PM) as symbolically connected to the death of Christ, complementing the Third Hour (Terce-9AM) the descent of the Holy Spirit at Pentecost and the Sixth Hour (Sext-12PM) the crucifixion in a mystical reflection on the Trinity and salvation historyEach of the Hours occurred at their set places to honor the timing of the events of Christ’s Passion. 

In the Divine Office, the Psalms are not merely personal reflections but are the “voice of the Bride herself addressed to her Bridegroom” — Christ speaking to the Father through the Church United States Conference of Catholic Bishops. This means that when we pray the Psalms, we are participating in the eternal dialogue of the Trinity: the Father speaks, the Son answers, and the Holy Spirit intercedes. The Psalms, rooted in the Old Testament, were also the words of Christ and the Apostles, and thus they become the living medium for this Trinitarian exchange.

How the Office Reflects the Trinity

  • Morning and Evening Prayer include Gospel canticles (Benedictus and Magnificat) that meditate on Christ’s life and mission, showing how the Son fulfills the Psalms in the New Covenant United States Conference of Catholic Bishops.
  • Midday Prayer and other hours use Psalms and hymns that echo the Trinitarian hymn of the angels: Holy, holy, holy, is the Lord of hosts (Isaiah 6:3), sung by the Father, Son, and Holy Spirit.
  • The Office of Readings and other scriptural readings from the Fathers and Church writers deepen the understanding of the Psalms in light of the Trinity’s work in salvation history United States Conference of Catholic Bishops.

Why This Matters

By praying the Psalms in the Divine Office, we are:

  • Joined to Christ’s prayer — the Church prays the same words Christ prayed to the Father.
  • Participating in the Trinitarian life — the Psalms become a bridge between our personal prayer and the eternal communion of the Trinity.
  • Sanctifying the day — each hour is a moment of praise, intercession, and thanksgiving, reflecting the rhythm of God’s own life.

In this way, the Divine Office is not just a schedule of prayer; it is a Trinitarian rhythm that keeps us in communion with God, the Church, and one another, drawing us into the very life of the Trinity.

For those who are new to praying the Divine Office, here are a few helpful tips to ensure your success:

  • Start simple. Choose one of the hours and aim for consistency in praying this hour. For example, pray Lauds (Morning Prayer) every day for a couple of weeks before attempting to add another hour.
  • Don’t begin by praying all the hours at once, or by picking an hour that is impractical for your schedule.
  • If things are going well and you would like to do more, add Vespers (Evening Prayer) to your daily routine. Continue to pray both Lauds and Vespers for an additional month. This may be enough for you, but, if you would like to add more, pray the Office of Readings and/or Compline as well.
  • The important thing is to develop a prayer habit that you can maintain while still attending to the duties of your state in life.

The Divine Office is intimately connected with the Holy Sacrifice of the Mass. Just as the Mass is continuously offered to God all over the world each day, so also is the Divine Office. At every hour of every day these communal prayers of the Church render glory to God and unite us with the saving work of Jesus Christ for the salvation of the world.  

The more Christian souls pray the Liturgy of the Hours, the better, because through the liturgy we participate in the saving work of Jesus Christ. In this way the laity can join the Church in praying for their own salvation and that of their family and loved ones, as well as for their nation and the whole world.
