The Eucharist is a liturgical meal of bread and wine, which is almost always preceded by a service of reading the Scriptures. Christians attribute the origin of the Eucharist to Jesus Christ himself at the Last Supper on the night before he died. Many Christians regard the Eucharist as a sacrament and as their central ritual, and many celebrate the Eucharist weekly or even more often. This sacred meal has had various names throughout history: the Lord’s Supper, Holy Communion, the Offering, the Divine Liturgy, the Mass. The most common name in the early 21st century, however, is Eucharist, which derives from the Greek word Eucharistia, a thanksgiving. What we know since the 3rd century as the basic form of the Christian Eucharist is most probably the result of a number of trajectories from the first 150 years of Christianity coming together, including: fellowship meals in remembrance of Jesus, celebrations of his passion and resurrection, and the tradition of his significant meals such as the Last Supper and the Supper at Emmaus (Luke 24). In the late 4th and 5th centuries, many local traditions coalesced to produce (1) a basic common form of Eucharistic liturgy consisting of entrance rite, liturgy of the word, homily, prayers, the sharing of a kiss of peace, presentation of gifts of bread and wine, Eucharistic prayer, Lord’s Prayer, fraction of the bread, distribution of communion, and dismissal; and (2) the various traditional liturgical families tied to major Christian cities: Byzantine (Constantinople, Jerusalem, Antioch), Coptic (Alexandria), East Syrian (Edessa), and Roman. The church of the first millennium knew a common affirmation of the understanding of Christ’s real presence in the Eucharistic elements as well as a variety of ways of expressing the notion of Eucharist as sacrifice. The first controversies over how to express Christ’s presence arose in the 9th century, and they rose to a crescendo with Berengar of Tours in the 11th century. The most sophisticated explanation of that presence (transubstantiation) was provided by Thomas Aquinas in the mid-13th century. The Protestant reformers of the 16th century made various criticisms of traditional Roman Catholic theology and practice. They insisted on using the language of the people, giving communion in both bread and wine, and dismissing the language of Eucharistic sacrifice. The Reformed tradition (John Calvin) and the Lutheran differed considerably, however, on how to affirm Christ’s presence in the Eucharistic celebration, with Luther taking a much more realist position and Calvin a more “spiritual” understanding. The Church of England was reluctant to take sides in this discussion and its own theological position on the Eucharist remains a matter of debate. The liturgical movement of the 19th and 20th centuries, combined with renewed interest in biblical and patristic scholarship, has produced a remarkable convergence among various Christian churches, and it has led to Eucharistic liturgies among Catholics, Anglicans, Lutherans, and Methodists that bear a notable similarity to one another.
Ancient Greek religion was a polytheistic religion without a book, church, creed, or a professional priestly class. Due to the extraordinarily rich regional varieties in cult, fragmentary evidence and conjectural interpretations of it, conflicting mythological accounts, and the span of time treated, not a single absolute statement can be made about any aspect of Greek religion and exceptions exist for every general rule stated here. Since Ancient Greeks perceived all aspects of nature as either divine or divinely controlled, and all aspects of individual and social life were thought to be subject to supernatural influence, paying proper respect to the gods and heroes was understood to be a fundamental necessity of life. Since no aspect of individual or social life was separate from “religion,” scholars refer to Ancient Greek religion as “embedded.”1 The closest Ancient Greek comes to the English word “religion” are the noun thrēskeia (“acts of religious worship, ritual, service of gods”) and the verb thrēskeuō (“to perform religious observances”). Basic components of religious worship were the construction and upkeep of divine precincts, statues, altars, and temples, the observance of festivals, performance of sacrifices, bloodless offerings and libations, prayer, hymning, and observance of ritual abstinences and purifications. The closest Greek equivalents to “belief” were eusebeia (“reverent piety,” “respect”) and pistis (“trust in others” or “faith”).2 Both words could qualify a relationship between humans, as well as a relationship between humans and a supernatural entity. Since the Ancient Greeks did not have authoritative or divinely sent books of revelation, there was no script telling them what or whom to believe in and outlining the reasons why. The Greeks did not have professional priests who preserved, interpreted, and disseminated religious norms.3 However, Greek literature is brimming with gods, and the stories about the gods, which they (and we) call “myths,” were not only in all their texts, but everywhere around them: depicted on their pottery, painted on their walls, chiseled on the stones of their buildings.4 In the public space, there were countless divine statues, and the temples, altars, sacred groves, and divine precincts were everywhere around them. Ancient Greeks learned about the gods by hearing, watching, and doing: by seeing their parents perform a sacrifice, by observing them as they prayed, swore an oath, or performed libations, by participating in processions, singing and dancing in the chorus, eating the sacrificial meat in the sanctuaries, and by drinking wine, the gift of Dionysus. Ancient Greeks had no immediate need for theodicy, for the gods could be either benevolent, or angry, and their benevolence was perceived as a sign that the worship the community offered was appropriate, whereas natural catastrophes, crippling defeats in wars, or epidemics were interpreted as manifestations of divine anger, provoked by some human error or misstep.5 Ancestral gods and heroes and the traditional way of worshipping them formed the cornerstone of Greek religiosity.
