Order of Mass

The Eucharist ( ; from , ), 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

It may also be called the epinikios hymnos (, "Hymn of Victory") when referring to the Greek rendition and parts of it are sometimes called "Benedictus". Tersanctus (Latin: "Thrice Holy") is another, rarer name for the Sanctus. The same name is sometimes used for the Trisagion.

A doxology (Ancient Greek: doxologia, from , doxa 'glory' and -, -logia 'saying') is a short hymn of praises to God in various forms of Christian worship, often added to the end of canticles, psalms, and hymns. The tradition derives from a similar practice in the Jewish synagogue, where some version of the Kaddish serves to terminate each section of the service.
