Catholic liturgy

Liturgy (from ) is a composite word meaning originally a public duty, a service to the state undertaken by a citizen. A leitourgos was "a man who performs a public duty", "a public servant", leitourgeo was "to do such a duty", leitourgema its performance, and leitourgia, the public duty itself. So in the use of liturgy meant the public official service of the Church, which corresponded to the official service of the Temple in the Old Law. ==Liturgical principles==

Catholic liturgies are broadly categorized as the Latin liturgical rites of the Latin Church and the Eastern Catholic liturgies of the Eastern Catholic Churches. The Catholic Church understands liturgy not only to mean the celebration of the Holy Mass, but also the celebration of the Liturgy of the Hours, bible services, and the administration of sacraments and many sacramentals. At the Second Vatican Council, the Council Fathers proclaimed the Constitution on the Sacred Liturgy, Sacrosanctum Concilium. There it says: The liturgy is considered as an exercise of the priestly office of Jesus Christ. The General Instruction on the Liturgy of the Hours states that, "as well as praising God, the Church's liturgy expresses the hopes and prayers of all the Christian faithful and intercedes before Christ and through him before the Father for the salvation of the whole world. As a result, the Catholic understanding of liturgy is not primarily about the precise regulation of individual sequences of rites, but rather about the essence of the church. Thus the Constitution on the Sacred Liturgy directs that The Codex Iuris Canonici, reflecting key principles from the Constitution on the Sacred Liturgy, expresses this in the following way: Pope John Paul II sees one part of the role of liturgy as "instil[ling] a taste for prayer", while the Directory on popular piety and the liturgy sees liturgy and life as inseparable: "Were the Liturgy not to have its effects on life, it would become void and displeasing to God". The Catechism of the Catholic Church explains: == Liturgical year ==

Ecclesiastical writer Anselm Schott OSB compares the liturgical year to a church building: as the liturgical service is limited in space by the walls of the church, so the church year it is enclosed by certain holy times. The liturgical year is made up of holy seasons, weeks and days. "The exact determination of the holy times is a basic condition of communal liturgical celebration, because only the determination of the day and hour makes the union for worship possible. The establishment of holy times for worship is part of the original structure of the liturgy, and observing them is considered a primary Christian duty." Apart from the liturgical seasons of the church year, the catholic liturgy knows ember days, rogation days and processions, services in the Roman station churches, votive masses and the feasts of Christ and his saints. ==Liturgical roles==

In addition to ordained ministers, the Constitution on the Sacred Liturgy affirmed that liturgical participation by all the faithful is both a right and a duty. Since the days of the apostles, singing has always transfigured the Christian liturgy. Gregorian chant, which "bears the stamp of holiness", is typical of the liturgy of the Roman Catholic Church. Pope Pius X and Pope Pius XI encouraged the singing of Gregorian chant by the people, "in order that the faithful may more actively participate in divine worship". The 1967 document Musicam sacram, which implemented the Constitution on the Sacred Liturgy, repeatedly mentions facilitating the full, active participation of the congregation as called for by the Council, so that "unity of hearts is more profoundly achieved by the union of voices". Musicam Sacram states: "One cannot find anything more religious and more joyful in sacred celebrations than a whole congregation expressing its faith and devotion in song. Therefore the active participation of the whole people, which is shown in singing, is to be carefully promoted." It calls for fostering this congregational participation through attention to choice of song directors, and to the nature of the congregation. It mentions the duty to achieve this participation on the part of choirs, choirs directors, pastors, organists, and instrumentalists. To achieve full, active participation of the congregation, great restraint in introducing new hymns has proven most helpful. To this end also, the General Instruction of the Roman Missal recommends use of seasonal responsorial psalms and also keeping to a song that all can sing while processing to Communion, to "express the communicants' union in spirit by means of the unity of their voices, to show joy of heart, and to highlight more clearly the 'communitarian' nature of the procession to receive Communion". == Liturgy of the Hours ==

The Liturgy of the Hours consecrates the whole course of day and night to God. Matins, Lauds and Vespers are major hours; little hours are Terce, Sext and None; Compline is the last canonical hour of the day. Members of the consecrated life are officially assigned by the church to intone the liturgy of the hours. They, as well as bishops, priests, and deacons, are obliged to pray at least the main parts of the Liturgy of the Hours vicariously for the faithful. Communities of contemplative orders are obliged to pray the liturgy of hours in choir. == Liturgical books and rubrics ==

The forms used in the Latin Church for the individual celebrations can be found in the liturgical books of the Roman Rite (Roman Missal, Rituale Romanum, Book of Hours, the Ceremonial of Bishops etc.) which were revised as part of the liturgical reform (and translated into the national languages). The Catholic liturgy also includes the liturgies of the various Eastern churches in communion with Rome, which follow their own oriental rites. The Constitution on the Sacred Liturgy also acknowledged scope for "legitimate variations and adaptations to different groups, regions, and peoples, especially in mission lands, provided that the substantial unity of the Roman rite is preserved". ==See also==
