Anaphora (liturgy) in the context of "Holy Qurbana"

The Eucharist (/ˈjuːkərɪst/ YOO-kər-ist; from Koine Greek: εὐχαριστία, romanized: eucharistía, lit. 'thanksgiving'), also called Holy Communion, the Blessed Sacrament or the Lord's Supper, is a Christian rite, considered a sacrament in most churches and an ordinance in others. Christians believe that the rite was instituted by Jesus Christ at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many". According to the synoptic Gospels, this was at a Passover meal.

The elements of the Eucharist, sacramental bread—either leavened or unleavened—and sacramental wine (among Catholics, Anglicans, Lutherans, Eastern Orthodox and Oriental Orthodox) or non-alcoholic grape juice (among Methodists, Baptists and Plymouth Brethren), are consecrated on an altar or a communion table and consumed thereafter. The consecrated elements are the end product of the Eucharistic Prayer.

The epiclesis (also spelled epiklesis; from Ancient Greek: ἐπίκλησις, lit. 'surname' or 'invocation') refers to the invocation of one or several gods. In ancient Greek religion, the epiclesis was the epithet used as the surname given to a deity in religious contexts. The term was borrowed into the Christian tradition, where it designates the part of the Anaphora (Eucharistic Prayer) by which the priest invokes the Holy Spirit (or the power of God's blessing) upon the Eucharistic bread and wine in some Christian churches. In most Eastern Christian traditions, the Epiclesis comes after the Anamnesis (remembrance of Jesus' words and deeds); in the Western Rite it usually precedes. In the historic practice of the Western Christian Churches, the consecration is effected at the Words of Institution, though during the rise of the Liturgical Movement, many denominations introduced an explicit epiclesis in their liturgies.

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 West Syriac Rite, also called the Syro-Antiochian Rite and the West Syrian Rite, is an Eastern Christian liturgical rite that employs the Divine Liturgy of Saint James in the West Syriac dialect. It is practiced in the Maronite Church, the Syriac Orthodox Church, the Syriac Catholic Church and various Malankara Churches of India (see the section on usage below). It is one of two main liturgical rites of Syriac Christianity, the other being the East Syriac Rite.It originated in the ancient Patriarchate of Antioch. It has more anaphora than any other rite.

Although the West Syriac liturgical tradition had always included many texts translated from Greek, this new influx of materials of Greek origin led to the emergence of two slightly different Syriac Orthodox traditions, that of Antioch, incorporating these new elements, and that of Tikrit, which did not incorporate it. It was essentially the Tikrit rite that was introduced into South India in the 18th and 19th century.

The Antiochene or Antiochian Rite refers to the family of liturgies originally used by the patriarch of Antioch. It includes the Liturgy of St James in Greek and Syriac, as well as other West Syriac Anaphoras.

The Canon of the Mass (Latin: Canon Missæ), also known as the Canon of the Roman Mass and in the Mass of Paul VI as the Roman Canon or Eucharistic Prayer I, is the oldest anaphora used in the Roman Rite of Mass. The name Canon Missæ was used in the Tridentine Missal from the first typical edition of Pope Pius V in 1570 to that of Pope John XXIII in 1962 to describe the part of the Mass of the Roman Rite that began after the Sanctus with the words Te igitur. All editions preceding that of 1962 place the indication "Canon Missae" at the head of each page from that point until the end of the Mass; that of 1962 does so only until the page preceding the Pater Noster and places the heading "Ordo Missae" on the following pages.

Before 1962, there were divergent opinions about the point where the Canon of the Mass ended. Some considered that it ended where indicated in the 1962 Roman Missal, others where indicated in the earlier editions from 1570 onwards (the end of Mass), others at the conclusion of the Embolism (Libera nos...) that expands on the final "Sed libera nos a malo" petition of the Pater Noster.
