Liturgy and worship, with church music

What is liturgy and worship, with church music?

Liturgy and worship, with church music, is the study of how the churches pray, worship and sing. Liturgy names public, ordered worship, above all the Eucharist; worship is the wider act of honoring God, set or free. It covers the early and historic rites, the church year, lectionaries and church music, and treats worship as a source of theology.

At a glance

Why it matters for reading Scripture

How the churches pray and worship. Many passages are known first through worship, and traditions differ on its form.

What the study found

Christian worship drew on Jewish Scripture, psalmody and prayer and the Lord's Supper, forming rite families and Reformation orders; most churches share Scripture, psalms and the Lord's Prayer, but differ on Communion frequency and calendar.

Where traditions divide

Traditions divide on set liturgy against free worship, what Scripture permits in worship, instruments and hymns, women leading, Latin or vernacular, Old or New Calendar, and contemporary worship music.

How the traditions compare

  • Roman Catholic Church

    Worships from authorized texts such as the Roman Missal, and makes "full and active participation by all the people" the aim to be considered before all else.

    It grounds its worship in received tradition as well as Scripture, as the Catechism's statement that the Church "believes as she prays" shows. The Second Vatican Council kept Latin in the Latin rites while allowing the vernacular to be extended, and held the pipe organ in high esteem; the 1967 instruction Musicam Sacram admits other instruments suited to sacred use. Since Traditionis Custodes (2021) the 1962 Missal is permitted only under the bishop's authority, and since 2021 lay women and men may be admitted to the instituted ministries of lector and acolyte.

    Sources1–7
  • Eastern Orthodox Church

    Worships from the authorized text of the Divine Liturgy, normally that of St John Chrysostom.

    The Orthodox Church in America states that the tradition of the Orthodox Church is to have no musical instruments in church, though organs are found in some Greek and Antiochian parishes in the United States. Orthodox churches divide over the Revised Julian calendar for fixed feasts, but all compute Easter on the Julian calendar, so Western and Orthodox Easter usually differ.

    Sources8–11
  • Old Calendarists

    Call themselves Genuine or True Orthodox and hold that the Church may not change its calendar, citing its long use and sixteenth-century Orthodox condemnations of the Gregorian reform.

    Churches using the revised calendar answer that it moves only fixed feasts and keeps the Orthodox Paschal reckoning. Keeping the Julian calendar is not itself Old Calendarism: most churches that keep Christmas on 7 January remain in communion with those that keep 25 December.

    Sources1012
  • Oriental Orthodox churches

    Worship from authorized texts: the Qeddase in the Ethiopian and Eritrean Orthodox Tewahedo churches, the Badarak in the Armenian Apostolic Church, and three liturgies, of St Basil, St Gregory of Nazianzus and St Cyril, in the Coptic Orthodox Church.

    Ge'ez remains the liturgical language of the Ethiopian church, alongside the people's language, and the church's own account names a large drum, a sistrum and a hand-bell in its music.

    Sources13–16
  • Anglican

    Worships from the Book of Common Prayer and other authorized books.

    The Articles of Religion give the Church "power to decree Rites or Ceremonies" and each national church authority to change them, provided nothing is ordained against God's Word written. With the Lutheran position, this is often summarized as a normative principle.

    Sources17–18
  • Lutheran

    Worships from Lutheran orders that go back to Luther's Formula Missae (1523) and Deutsche Messe (1526).

    The Augsburg Confession holds that human ceremonies need not be alike everywhere, and keeps rites that may be observed without sin and serve order and peace.

    Sources19–21
  • Reformed (regulative principle)

    The Westminster Confession allows in worship only what Scripture prescribes, and its defenders state this as a charter of liberty: "God alone is Lord of the conscience", so no church may impose worship that Scripture does not command.

    Circumstances of worship are left to Christian prudence, and the Westminster Directory gave headings for prayer instead of fixed texts. Reformed churches that hold the principle differ over whether hymns and instruments meet its test.

    Sources22–23
  • Exclusive psalmody

    In its strictest form the regulative principle excludes both hymns and instruments.

    The Free Presbyterian Church of Scotland excludes "all materials of praise other than the inspired Psalms" and allows "only the human voice", and the Reformed Presbyterian Church of North America holds "a capella singing and the exclusive use of the Psalms".

    Sources24–25
  • Methodist

    John Wesley's Sunday Service (1784) was his abridgement and revision of the 1662 Prayer Book.

    Methodists on the American frontier set it aside for extemporaneous prayer, while British Methodists used Wesley's abridgement alongside the Prayer Book.

    Sources26–27
  • Quakers

    Quakers in Britain describe worship as a shared act that is "never" an individual activity and prize "silent waiting upon the Lord".

    A meeting has no set leader and any Friend may minister; spoken ministry should come from a sense of leading.

    Sources28
  • Pentecostal and charismatic

    Services leave room for the gifts of the Spirit: in seven of the ten countries Pew surveyed in 2006, at least half of Pentecostals said their services often include them.

    Raised hands, shouting and dance belong to the worship, as the Azusa Street accounts describe.

    Sources29–30
  • Churches of Christ (Stone-Campbell)

    The churches of Christ of the Stone-Campbell movement mostly worship without instruments, holding that instruments are an unauthorized change from the early church.

    The Christian churches of the same movement use them as a matter of congregational choice.

    Sources31–32
  • Contemporary worship music: supporters

    Swee Hong Lim and Lester Ruth trace contemporary worship to the vernacular worship of the post-war decades, the choruses of the Jesus People and above all Pentecostal practice, in which a time of praise leads the congregation into the presence of God.

    Supporters also point to participation, accessible language and songs that congregations learn quickly.

    Sources33–34
  • Contemporary worship music: critics

    Ask what a narrow set of sources and a commercial market do to the breadth of what churches sing; one study of the CCLI and PraiseCharts Top 25 lists tied 37 of 38 leading songs released from 2010 to 2020 to five churches.

    The researchers themselves draw no conclusion on theology, and Leah Payne attributes the concentration to the fact that most worshippers attend large churches.

    Sources35–36

How the field developed

  1. Early church
    Mid 2nd century

    Justin Martyr's First Apology, written in Rome, gives the first full outline of a Sunday service: readings, instruction, prayer, bread, wine and water, thanksgiving and a collection for those in need. Justin gives two reasons for Sunday: God began creation on that day, and Christ rose on it.37

  2. Late antiquity
    325

    The Council of Nicaea does not fix the date of Easter by a numbered canon, but its synodal letter reports agreement that the churches of the East keep the feast at the same time as Rome and Alexandria. The council tells Christians to pray standing on Sundays and through the fifty days of Pentecost.38

  3. Late antiquity
    Late 4th century

    Egeria, a pilgrim, describes worship in Jerusalem: hymns and psalms before dawn, prayer at fixed hours, a Sunday vigil with the reading of the Resurrection, an eight-day Epiphany feast and an eight-week Lent.39

  4. Late antiquity
    6th century

    The Ethiopian Church traces its chant, zema, and the three modes still in use to Yared, a sixth-century Aksumite composer and saint, whose hymnary, the Deggwa, is described as the oldest literary work in Ge'ez.4016

  5. Reformation
    1523 and 1526

    Luther publishes the Formula Missae, in Latin, which keeps much of the historic Mass but removes the Canon, and then the Deutsche Messe, a German service with hymns in place of much of the old text.1920

  6. Reformation
    1549 to 1662

    The Church of England's first Book of Common Prayer appears in 1549, followed by the books of 1552 and 1559; the 1662 book is described as the current official Prayer Book.17

  7. Reformation
    1562

    The Genevan Psalter, begun by Calvin in Strasbourg in 1539, is completed with all 150 psalms, in texts by Clément Marot and Théodore de Bèze. The complete psalter uses 125 tunes in 110 meters, almost all syllabic.414243

  8. Reformation
    January 1645

    A Parliamentary ordinance orders that the Book of Common Prayer "shall not be used" and the Westminster Directory for the Public Worship of God "shall be observed". The Directory gives headings and the sense of prayers rather than fixed texts.4423

  9. Modern
    1784

    John Wesley sends the American Methodists The Sunday Service of the Methodists in North America, his abridgement and revision of the 1662 Prayer Book.2645

  10. Modern
    1867 and 1871

    Slave Songs of the United States, the first published collection of spirituals, appears in 1867. In 1871 Fisk University sends out its Jubilee Singers, who begin singing spirituals as encores, and the response makes them the core of their concerts.4647

  11. Modern
    1906

    The Azusa Street revival in Los Angeles, led by William Seymour from April 1906 to about 1909, is widely treated as the start of the worldwide Pentecostal movement.4830

  12. Modern
    May 1923

    An inter-Orthodox congress at Constantinople under Patriarch Meletios IV, not attended by all churches, adopts a revised calendar for fixed feasts; Easter is still computed on the Julian calendar.10

  13. Modern
    1926

    Virgil Michel founds Orate Fratres at Saint John's Abbey, Collegeville, on the First Sunday of Advent. It carries the liturgical movement into the English-speaking world, and in 1951 takes the name Worship to signal support for the vernacular.49

  14. Modern
    4 December 1963

    The Second Vatican Council promulgates Sacrosanctum Concilium, which makes "full and active participation by all the people" the aim to be considered before all else and asks that "a more representative portion of the holy scriptures" be read over a set number of years.2

  15. Modern
    1969

    Paul VI's constitution Missale Romanum adds three new Eucharistic Prayers and sets Sunday readings on a three-year cycle, and the Roman Lectionary for Mass gives three readings on Sundays, from the Old Testament, an apostle and the Gospel.150

  16. Modern
    1992

    The North American Consultation on Common Texts publishes the Revised Common Lectionary, reworking the adaptations that many Protestant churches had made of the 1969 Roman lectionary.51

How to study liturgy and worship, with church music

The questions it asks

  • What do liturgy, rite, office and ordo mean, and how is worship studied?5253
  • Where did Christian worship come from, and what do the earliest sources actually show?
  • How far can Christian worship be traced to the temple and the synagogue?
  • How do rites grow, and what are the great rites of East and West?54
  • Does the Church believe as it prays, so that worship is a source of theology?3
  • How does each church keep its calendar and choose its readings?
  • How do the churches sing, from chant to metrical psalms, hymns, spirituals and contemporary worship music?

Its method

Start
  1. Read the earliest sources, the Didache, Justin Martyr, the Apostolic Tradition and Egeria, with the disputes over their date and authorship5537565739.

  2. Separate historical liturgics, which establishes structures and their development, from liturgical theology, which discovers their meaning58.

  3. Compare rites by Baumstark's comparative method, which studies how rites grow by small local steps, as Robert Taft did for the Byzantine Divine Liturgy5459.

  4. Group the rites in their families, Antiochene, Alexandrian, Gallican and Roman, as later scholarship has refined that map60.

  5. Describe each rite from its own texts and official sources: its structure, language and texts861.

  6. Read the lectionaries to see which parts of Scripture each church reads aloud and how it pairs Old and New Testament readings506263.

  7. Treat the so-called laws of liturgical development as contested: a 2018 article argues that liturgy behaves less like an evolving species than like a self-regulating ritual system64.

  8. Where sources disagree, give each with its own hedges, as with the rival reconstructions of the Apostolic Tradition5657.

Key terms

The words that carry the most weight in this field, each defined from the sources of this study. Turn a card over to read its definition.

The church's public, ordered worship, above all the Eucharist.

The wider act of honoring God, set or free.

A historically distinct body of worship, with its texts, ceremonial, chant and calendar, proper to a church or family of churches52.

The daily office: the cycle of prayer at fixed hours, which Egeria already found in Jerusalem in the fourth century39.

Both the book that orders a service and, in liturgical theology, the underlying pattern that makes worship recognizably Christian; Gordon Lathrop sets it out as bath, word, table and prayer53.

The phrase that ties prayer to belief; the Catechism of the Catholic Church states that "the law of prayer is the law of faith: the Church believes as she prays"3.

Aidan Kavanagh's name for the liturgy as primary theology, from which secondary, systematic theology is drawn74.

The principle, stated in the Westminster Confession, that allows in worship only what Scripture prescribes22.

The Byzantine book of the eight tones, which collects the hymns of the weekly cycle8069.

Reading a psalm line by line before it is sung, where many could not read81.

Questions people ask

Many Orthodox churches compute Easter on the Julian calendar, now thirteen days behind the Gregorian10. In 2026 Western Easter fell on 5 April and Orthodox Easter on 12 April; in 2027 they fall on 28 March and 2 May, and in 2028 both fall on 16 April8211. On 29 November 2025 Leo XIV and Ecumenical Patriarch Bartholomew signed a joint declaration committing them to "continue the process of exploring a possible solution for celebrating together the Feast of Feasts every year"83.

The usual Byzantine Divine Liturgy has none63. The exceptions are the Liturgies joined to Vespers, on Holy Thursday, Holy Saturday and in some years the eves of the Nativity and Theophany and the Annunciation84. Otherwise Old Testament readings come at Vespers on the eves of feasts, and on weekdays of Great Lent Isaiah is read at the Sixth Hour and Genesis and Proverbs at Vespers8586.

It was identified in the early twentieth century as his work57. Paul Bradshaw, Maxwell Johnson and Edward Phillips argue that it is neither by Hippolytus nor by any one author, but a composite of layers of diverse origin compiled over time, while Alistair Stewart sees a stronger Roman and Hippolytan connection and places it broadly in the third century568757. The question matters because the second Eucharistic Prayer of the 1970 Roman Missal draws on its anaphora88.

The Orthodox Church in America states that the tradition of the Orthodox Church is to have no musical instruments in church, and that the instruments of Psalm 150 did not carry into Christian worship9. Most churches of Christ hold that instruments are an unauthorized change from the early church31. Some Reformed churches sing psalms only, with "only the human voice", on the strictest form of the regulative principle2425. The Catholic Church, by contrast, holds the pipe organ in high esteem2.

In part: the Roman lectionary and the Revised Common Lectionary share a three-year Gospel pattern, reading mostly Matthew in Year A, Mark in Year B and Luke in Year C8962. They pair the Old Testament with the Gospel differently: the Roman lectionary selects Old Testament texts mainly for their correlation with the New Testament readings, while the Revised Common Lectionary offers, after Pentecost, a semicontinuous track beside a complementary track tied to the Gospel5062.
