Liturgy in the context of Community

The Greek Orthodox Patriarchate of Jerusalem, also known as the Greek Orthodox Church of Jerusalem, is an autocephalous church within the wider communion of Eastern Orthodox Christianity. Established in the mid-fifth century as one of the oldest patriarchates in Christendom, it is headquartered in the Church of the Holy Sepulchre in Jerusalem and led by the patriarch of Jerusalem, currently Theophilos III. The patriarchate's ecclesiastical jurisdiction includes roughly 200,000 to 500,000 Orthodox Christians across the Holy Land in Palestine, Jordan and Israel.

The church traces its foundation in Jerusalem to the day of Pentecost, when the Holy Spirit, according to Christian beliefs, descended on the disciples of Jesus Christ and ushered the spread of the Gospel. The church celebrates its liturgy in the ancient Byzantine Rite – whose sacred language, Koine Greek, is the original language of the New Testament – and follows its own liturgical year under the Julian calendar.

In Christian theology, ecclesiology is the study of the Church, the origins of Christianity, its relationship to Jesus, its role in salvation, its polity, its discipline, its eschatology, and its leadership.

In its early history, one of the Church's primary ecclesiological issues had to do with the status of Gentile members in what had become the New Testament fulfilment of the essentially Jewish Old Testament church. It later contended with such questions as whether it was to be governed by a council of presbyters or a single bishop, how much authority the bishop of Rome had over other major bishops, the role of the Church in the world, whether salvation was possible outside of the institution of the Church, the relationship between the Church and the State, and questions of theology and liturgy and other issues. Ecclesiology may be used in the specific sense of a particular church or denomination's character, self-described or otherwise. This is the sense of the word in such phrases as Catholic ecclesiology, Protestant ecclesiology, and ecumenical ecclesiology.

Ordination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized (usually by the denominational hierarchy composed of other clergy) to perform various religious rites and ceremonies. The process and ceremonies of ordination may vary by religion and denomination. One who is in preparation for, or who is undergoing, the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is commonly found in a book known as an Ordinal which provides the ordo (ritual and rubrics) for celebrations.

Prayer is an invocation or act that seeks to activate a rapport with an object of worship through deliberate communication. In the narrow sense, the term refers to an act of supplication or intercession directed towards a deity or a deified ancestor. More generally, prayer can also have the purpose of giving thanks or praise, and in comparative religion is closely associated with more abstract forms of meditation and with charms or spells.

Prayer can take a variety of forms: it can be part of a set liturgy or ritual, and it can be performed alone or in groups. Prayer may take the form of a hymn, incantation, formal creedal statement, or a spontaneous utterance in the praying person.

The Vedic period, or the Vedic age (c. 1500 – c. 500 BCE), is the period in the late Bronze Age and early Iron Age of the history of India when the Vedic literature, including the Vedas (c. 1500–900 BCE), was composed in the northern Indian subcontinent, between the end of the urban Indus Valley Civilisation and a second urbanisation, which began in the central Indo-Gangetic Plain c. 600 BCE. The Vedas are liturgical texts which formed the basis of the influential Brahmanical ideology, which developed in the Kuru kingdom, a tribal union of several Indo-Aryan tribes. The Vedas contain details of life during this period that have been interpreted to be historical and constitute the primary sources for understanding the period. These documents, alongside the corresponding archaeological record, allow for the evolution of the Indo-Aryan and Vedic culture to be traced and inferred.

The Vedas were composed and orally transmitted with precision by speakers of an Old Indo-Aryan language who had migrated into the northwestern regions of the Indian subcontinent early in this period. The Vedic society was patriarchal and patrilineal. Early Indo-Aryans were a Late Bronze Age society centred in the Punjab, organised into tribes rather than kingdoms, and primarily sustained by a pastoral way of life.

A church service (or a worship service) is a formalized period of Christian communal worship, often held in a church building. Most Christian denominations hold church services on the Lord's Day (offering Sunday morning and Sunday evening services); a number of traditions have mid-week services, while some traditions worship on a Saturday. In some Christian denominations, church services are held daily, with these including those in which the seven canonical hours are prayed, as well as the offering of the Mass, among other forms of worship. In addition to this, many Christians attend services on holy days such as Christmas, Ash Wednesday, Good Friday, Ascension Thursday, among others depending on the Christian denomination.

The church service is the gathering together of Christians to be taught the "Word of God" (the Christian Bible) and encouraged in their faith. Technically, the church in "church service" refers to the gathering of the faithful rather than to the physical place in which it takes place. In most Christian traditions services are presided over by clergy wherever possible, but some traditions utilize lay preachers. Styles of service vary greatly, from the Catholic, Lutheran, Eastern Orthodox, Oriental Orthodox, Reformed (Continental Reformed, Presbyterian and Congregationalist) and Anglican traditions of liturgical worship to informal worship characterized by certain free church traditions, common among Methodists and Baptists, that often combine worship with teaching for the believers, which may also have an evangelistic component appealing to backsliders and the non-Christians in the congregation (cf. altar call). Quakers and some other groups have no formal outline to their services, but allow the worship to develop as the participants present feel moved.

Ecclesiastical Latin, also called Church Latin or Liturgical Latin, is a form of Latin developed to discuss Christian thought in late antiquity and used in Christian liturgy, theology, and church administration to the present day, especially in the Catholic Church. It includes words from Vulgar Latin and Classical Latin (as well as Greek and Hebrew) re-purposed with Christian meaning. It is less stylized and rigid in form than Classical Latin, sharing vocabulary, forms, and syntax, while at the same time incorporating informal elements which had always been with the language but which were excluded by the literary authors of Classical Latin.

Its pronunciation was partly standardized in the late 8th century during the Carolingian Renaissance as part of Charlemagne's educational reforms, and this new letter-by-letter pronunciation, used in France and England, was adopted in Iberia and Italy a couple of centuries afterwards. As time passed, pronunciation diverged depending on the local vernacular language, giving rise to even highly divergent forms such as the traditional English pronunciation of Latin, which has now been largely abandoned for reading Latin texts. Within the Catholic Church and in certain Protestant churches, such as the Anglican Church, a pronunciation based on modern Italian phonology, known as Italianate Latin, has become common since the late 19th century.

The Christian Gospels of Mark and Matthew say that, after the Ascension of Jesus, his Apostles "went out and preached everywhere". This is described in Mark 16 verses 19 and 20, and Matthew 28 verses 19 and 20. According to a tradition mentioned by Eusebius, they dispersed to distinct parts of the world. In the Middle Ages, a liturgical feast of the Dispersion of the Apostles was celebrated to commemorate their missionary work and their founding the apostolic sees. This annual feast was held on 15 July and ranked as a major double.

The Acts of the Apostles, the canonical sequel to the Gospel of Luke, portrays the dispersal as occurring a substantial time after the ascension, with the ministry staying in Jerusalem at first and spreading from there beginning with the conversion of the Ethiopian eunuch.

Anglicanism, also known as Episcopalianism in some countries, is a Western Christian tradition which developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents within the Anglican Communion, and more than 400,000 outside of the Anglican Communion, worldwide as of 2025.

Adherents of Anglicanism are called Anglicans; they are also called Episcopalians in some countries. Most are members of national or regional ecclesiastical provinces of the international Anglican Communion, one of the largest Christian bodies in the world, and the world's third-largest Christian communion. The provinces within the Anglican Communion have historically been in full communion with the See of Canterbury and thus with the archbishop of Canterbury, whom the communion refers to as its primus inter pares (Latin, 'first among equals'). The archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the president of the Anglican Consultative Council. Some churches that are not part of the Anglican Communion or recognised by it also call themselves Anglican, including those that are within the Continuing Anglican movement and Anglican realignment.

Invocation is the act of calling upon a deity, spirit, or supernatural force, typically through prayer, ritual, or spoken formula, to seek guidance, assistance, or presence. It is a practice found in numerous religious, spiritual, and esoteric traditions, where it serves to establish a connection between the human and the divine or metaphysical realms. Invocation can be directed toward a singular deity, multiple deities, spirits, or abstract forces, and may involve formal liturgies, spontaneous prayers, chants, or symbolic actions. Unlike evocation, which is generally understood as calling a spirit to appear outside the practitioner, invocation often implies inviting the entity to be present within or to closely align with the practitioner.

The purpose of invocation varies across cultural and religious contexts. In many traditions, it is used to request divine intervention, protection, wisdom, or blessings in personal or communal matters. Invocation may also serve to consecrate a space, mark the beginning of a sacred ritual, or facilitate a deeper spiritual experience. In mystical or esoteric practices, invocation can be a means of aligning oneself with a higher spiritual principle or archetype, fostering personal transformation or enlightenment. In some traditions, the practitioner ritually identifies with the deity or spiritual figure. This is distinct from possession, where the invoked being is believed to inhabit or act through the practitioner directly and autonomously.

Western Rite Orthodoxy, also called Western Orthodoxy or the Orthodox Western Rite, are congregations within the Eastern Orthodox tradition which perform their liturgy in Western forms.

Besides altered versions of the Tridentine Mass, congregations have used Western liturgical forms such as the Sarum Rite, the Mozarabic Rite, and Gallican Rite. Some congregations use what has become known simply as the English Liturgy, which is derived from the Anglican Book of Common Prayer, albeit with some Byzantinization intended to emphasize Eastern Orthodox theological teaching. The Western Rite that exists today has been heavily influenced by the life and work of Julian Joseph Overbeck.

The Words of Institution, also called the Words of Consecration, are words echoing those of Jesus himself at his Last Supper that, when consecrating bread and wine, Christian eucharistic liturgies include in a narrative of that event. Eucharistic scholars sometimes refer to them simply as the verba (Latin for "words").

Almost all existing ancient Christian churches explicitly include the Words of Institution in their eucharistic celebrations and consider them necessary for the validity of the sacrament. This is the practice of the Catholic Church's Latin liturgical rites and Eastern Catholic liturgies, the Eastern Orthodox Church, and all the Oriental Orthodox Churches, including the Armenian, the Coptic, the Ethiopian and the Malankara, as well as the Anglican Communion, Lutheran churches, Methodist churches, and Reformed churches. The only ancient eucharistic ritual still in use that does not explicitly contain the Words of Institution is the Holy Qurbana of Addai and Mari, used for part of the year by the Church of the East denominations, namely Assyrian Church of the East, Ancient Church of the East, and the Chaldean Syrian Church, due to their tradition of using the Holy Leaven. The Chaldean Catholic Church and the Syro-Malabar Church, two of the Eastern Catholic Churches, use the same Anaphora, but insert in it the Words of Institution. However, groups authorized by the Catholic Church to review the Qurbana recognized the validity of this eucharistic celebration in its original form, without explicit mention of the Words of Institution, saying that "the words of Eucharistic Institution are indeed present in the Anaphora of Addai and Mari, not in a coherent narrative way and ad litteram, but rather in a dispersed euchological way, that is, integrated in successive prayers of thanksgiving, praise and intercession."

The Gathas (/ˈɡɑːtəz, -tɑːz/) are five hymns in the Avestan language from the Zoroastrian oral tradition of the Avesta. The oldest surviving text fragment dates from 1323 CE, but they are believed by scholars to have been composed before 1000 BCE and passed down orally for centuries. They are traditionally believed to have been composed by the prophet Zarathushtra (Zoroaster) himself. They form the core of the Zoroastrian liturgy (the Yasna). They are arranged in five different modes or metres.

The Avestan term gāθā (𐬔𐬁𐬚𐬁 "hymn", but also "mode, metre") is cognate with Sanskrit gāthā (गाथा), both from the Proto-Indo-Iranian word *gaHtʰáH, from the root *gaH- "to sing".

A devotional song is a hymn that accompanies religious observances and rituals. Traditionally devotional music has been a part of Hindu music, Jewish music, Buddhist music, Islamic music and Christian music.

Each major religion has its own tradition with devotional hymns. In Christianity, the devotional has been a part of the liturgy in Roman Catholicism, Lutheranism, the Greek Orthodox Church, the Russian Orthodox Church, and others, since their earliest days. A devotional is a part of the prayer service proper and is not, in these contexts, ornamentation. Within the Reformed tradition, church music in general was hotly debated; some Puritans objected to all ornament and sought to abolish choirs, hymns, and, inasmuch as liturgy itself was rejected, devotionals.

Hildegard of Bingen OSB (German: Hildegard von Bingen, pronounced [ˈhɪldəɡaʁt fɔn ˈbɪŋən]; Latin: Hildegardis Bingensis; c. 1098 – 17 September 1179), also known as the Sibyl of the Rhine, was a German Benedictine abbess and polymath active as a writer, composer, philosopher, mystic, visionary, and as a medical writer and practitioner during the High Middle Ages. She is one of the best-known composers of sacred monophony, as well as the most recorded in modern history. She has been considered by a number of scholars to be the founder of scientific natural history in Germany.

Hildegard's convent at Disibodenberg elected her as magistra (mother superior) in 1136. She founded the monasteries of Rupertsberg in 1150 and Eibingen in 1165. Hildegard wrote theological, botanical, and medicinal works, as well as letters, hymns, and antiphons for the liturgy. She wrote poems, and supervised miniature illuminations in the Rupertsberg manuscript of her first work, Scivias. There are more surviving chants by Hildegard than by any other composer from the entire Middle Ages, and she is one of the few known composers to have written both the music and the words. One of her works, the Ordo Virtutum, is an early example of liturgical drama and arguably the oldest surviving morality play. She is noted for the invention of a constructed language known as Lingua Ignota.
