The Eucharist, 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 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.
Agnus Dei is the Latin name under which the "Lamb of God" is honoured within Christian liturgies descending from the historic Latin liturgical tradition, including those of Roman Catholicism, Lutheranism and Anglicanism.

Mass is the main Eucharistic liturgical service in many forms of Western Christianity.

The epiclesis 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 by which the priest invokes the Holy Spirit upon the Eucharistic bread and wine in some Christian churches. In most Eastern Christian traditions, the Epiclesis comes after the Anamnesis ; 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.
Closed communion is the practice of restricting the serving of the elements of Holy Communion to those who are members in good standing of a particular church, denomination, sect, or congregation.

This restriction is based on various parameters, one of which is baptism. See also intercommunion.
Making the sign of the cross, also known as blessing oneself or crossing oneself, is a ritual blessing made by members of some branches of Christianity.

Amen."
