Eucharist

Eucharist is from the Greek eucharistia (εὐχαριστία), meaning thanksgiving or the giving of thanks[1]. The word derives from eu (good, well) and the root charis (grace, gift, favor)[1]. The earliest Christian writings use this term for the central liturgical meal commemorating the Last Supper of Jesus with his disciples[2]. The verb eucharisto appears in the New Testament accounts of the Last Supper to describe Jesus giving thanks over the bread and cup[3].

views on presence, symbolism, and access differ strongly across Christian traditions.

The Eucharist is one of the central sacraments of Christian worship[2]. In Catholic, Orthodox, Anglican, and many Lutheran and other Protestant traditions, the rite involves the consecration of bread and wine accompanied by recitation of the words of institution from the Last Supper, the great thanksgiving prayer, and the distribution of the consecrated elements to the gathered community[4].

The theological understanding of what happens in the Eucharist differs sharply across traditions[5]. Catholic teaching speaks of transubstantiation: the bread and wine become the body and blood of Christ in substance while retaining the appearances of bread and wine[6]. Eastern Orthodox theology affirms the real presence of Christ in the Eucharist without using the specific philosophical category of transubstantiation[7]. Lutheran theology speaks of consubstantiation or the real presence in, with, and under the elements[5]. Reformed and many Protestant traditions emphasize spiritual presence and memorial[5]. Some traditions (Quakers, Salvation Army) do not celebrate Eucharist at all, emphasizing direct spiritual communion without ritual elements[2].

The frequency of Eucharist also varies[2]. Catholic Mass typically includes Eucharist daily and is required of practicing Catholics on Sundays[6]. Eastern Orthodox liturgy centers Eucharist, traditionally celebrated weekly[7]. Many Protestant traditions celebrate weekly, monthly, or quarterly[2]. Across traditions, the Eucharist is often called by other names: Communion, Holy Communion, the Lord's Supper, the Divine Liturgy, the Mass, the Breaking of Bread[2].

Eucharistic theology is one of the most extensively developed and most divisive areas of Christian thought[5]. The medieval debates that shaped Catholic teaching, the Reformation-era controversies between Luther, Zwingli, and Calvin, and modern ecumenical conversations have all produced major theological literature[5]. Liturgical studies traces the historical development of Eucharistic prayer forms[8]. Contemporary scholarship by Geoffrey Wainwright, Alexander Schmemann, and others has explored Eucharistic theology across traditions[7].
