Divine Liturgy

The first part, termed the "Liturgy of the Catechumens", includes like a synagogue service the reading of scriptures and, in some places, perhaps a sermon/homily.

As numbers in a diocese increased dramatically, the bishop who presides over the Eucharistic assembly appointed presbyters to act as celebrants in the local communities (the parishes).

[3] The format of Divine Liturgy is fixed, although the specific readings and hymns vary with season and feast.

Almost all texts are chanted throughout the Divine Liturgy, not only hymns but litanies, prayers, creed confession and even readings from the Bible, depending on tradition.

In ancient rubrics, and contemporary Greek practice, the sermon, Nicene Creed and the Lord's Prayer are spoken/read, rather than chanted.

The last part of the offertory resembles an anaphora: after a dialogue, the priest blesses the congregation and proclaims a prayer of thanksgiving, giving thanks to God for his support to us, and asking him for a worthy participation to the liturgy.

Then comes the prayer of covering said inaudibly by the priest, which has the form of an epiclesis asking God to show his face on the gifts, and to change them in order that the bread and wine may became the Body and Blood of Christ.

After the Trisagion follows a litany, the recital of a Psalm and the singing of the Alleluia, and finally the proclamation of the Gospel from the doors of the sanctuary.

After the anaphora takes place the consignation,[16] i.e. the moistening of the Lamb with some drops of the consecrated Wine, which is shown for the worship of the faithful.

The priest makes a second consignation and puts gently the ispakidon in the chalice (the commixture),[17] then he recites aloud a confession of faith.

Basil and St. John Chrysostom took more than four hours), and in that it can be used with more than eighty different anaphoras; the most commonly used are those of Mar Bar Salibi (which is the shortest), and that of St. James, which resembles that of the Byzantine Rite liturgy, and is mandated on certain occasions, such as major feasts, the consecration of churches, and the first liturgies offered by newly ordained priests.

This is in distinction from the other liturgies of the Oriental Orthodox Churches (Coptic, West Syrian, Ethiopic) which have retained multiple anaphora.

The roots of the liturgy lie in the West Syrian and Byzantine forms, with the influence of the Roman Catholic Mass, the latter having arrived likely during the period of the Fourth Crusade or shortly thereafter.

[citation needed] Among the distinctive practices of the Armenian Patarag is the tradition that on the Sundays of the fast before Easter (the Great Fast) the curtain which hangs down in front of the elevated altar area (Armenian խորան khoran) is never opened – even for the reading of the Gospel, certain movable parts of the liturgy are omitted, the parts of the liturgy sung by the choir are said or chanted simply without adornment, there is no general confession, and there is no distribution of Communion to the faithful.

This practice of fasting from the Communion bread in preparation for Easter may reflect an ancient custom of the church in Jerusalem.

[citation needed] One element which almost certainly derives from the influence of Western liturgy is the reading of a last Gospel at the conclusion of the Patarag.

However, the celebration of a short memorial service for one or more departed persons (Հոգեհանգիստ hogehangist, Western Armenian hokehankist, meaning 'rest of the spirit') is quite prevalent in parishes and replaces the reading of the last Gospel.

[citation needed] The following description of the celebration of Mass, usually in the local vernacular language, is limited to the form of the Roman Rite promulgated after the Second Vatican Council (1962–1965) by Pope Paul VI in 1969 and revised by Pope John Paul II in 2002, largely replacing the usage of the Tridentine Mass form originally promulgated in 1570 in accordance with decrees of the Council of Trent in its closing session (1545–46).

The 1962 form of the Tridentine Mass, in the Latin language alone, may be employed where authorized by the Holy See or, in the circumstances indicated in the 2021 document Traditionis custodes,[26] by the diocesan bishop.

In the modern form the priest usually (though not obligatorily) faces the people (versus populum); in the earlier form the priest most often faces in the same direction as the people, towards the apse of the church, a stance that since the twentieth century is often called ad orientem, although not necessarily eastward.
