Article 2: The Eucharist through Christian History

Early Church Belief and Practice Before Medieval Definitions

• By the early second century, surviving Christian texts speak of the Eucharist with striking realism.

• Justin Martyr explained that Eucharistic food is received “not as common bread and common drink" but as the flesh and blood of the incarnate Jesus, while acknowledging it is a ritual food blessed by prayer and the words of institution.

• Ignatius of Antioch used the Eucharist as a doctrinal “front line” against groups denying Christ’s true bodily suffering, criticising those who abstained because they "confess not the Eucharist to be the flesh of our Saviour Jesus Christ."

• Ignatius also introduced pastoral, healing language echoed by later Christians, calling the bread “the medicine of immortality” and an “antidote” against death.

• Irenaeus of Lyons linked the Eucharist, the incarnation, and bodily resurrection, stating that once bread “receives the invocation of God", it possesses “two realities” and gives believers “the hope of the resurrection".

• It is a modern misunderstanding to assume early Christians used "symbol" language merely to mean a mental reminder. Historic Orthodox explanations show that the bread and wine are called “mysteries and symbols” precisely because they truly mediate God’s presence, not because they reduce the rite to a bare memorial.

Fourth-Century Deepening: "Change", Epiclesis, and Words of Institution

• By the fourth century, explicit language of change appeared in catechetical teachings linked to baptism and first communion.

• Cyril of Jerusalem described the church praying for God to "send forth His Holy Spirit upon the gifts" so the bread and wine become Christ’s body and blood, noting that what the Spirit touches is “sanctified and changed.”

• In the Latin West, emphasis was placed on the power of Christ’s own words spoken by the minister; Ambrose of Milan argued the sacrament is created “by the word of Christ", connecting "This is My Body" to a consecration and a change beyond sensory reporting.

• Gregory of Nyssa taught that bread and wine “sanctified by the Word” are "changed into the Body" of the Word, viewing it as a true transformation engineered by God.

• These fourth-century patterns highlight two early emphases that later polarised East and West: (a) the vital invocation of the Holy Spirit (epiclesis) for consecration and (b) the decisive force of Christ's dominical words.

Medieval Latin Developments: Defining Transubstantiation and Regulating Reception

• In the Western Middle Ages, theologians heavily debated how Christ is present. The term 'transubstantiation' emerged in the 12th century to define Christ’s true presence alongside the unchanged sensory appearances of bread and wine.

• The 9th century saw early pressure for precision: Paschasius Radbertus wrote an influential monograph arguing for a literal presence, while Ratramnus replied that the elements are “mystic symbols” operating by faith, remaining unchanged in actuality but changed symbolically.

• In the 11th century, Berengar of Tours sided with Ratramnus’s symbolic approach but was repeatedly condemned by figures like Lanfranc and multiple synods.

• In 1215, the Fourth Lateran Council officially declared the bread is “changed (transsubstantiatio) ... into the body, and the wine into the blood,” while contained “under the forms of bread and wine.”

• In the 13th century, Thomas Aquinas offered a classic scholastic explanation using Aristotle's concepts: the "substance" of the elements changes, while the "accidents" (taste, appearance) remain.

• Reverence for the elements shifted Western practices. While communion under both kinds was normal for over a millennium, reception of bread alone grew from the 11th century onwards.

• The Council of Constance (Session 13 in 1415) defended reception under one kind to "avoid various dangers and scandals", asserting that "the whole body and blood of Christ are truly contained" under either form alone.

• In the 16th century, the Council of Trent reaffirmed transubstantiation ("a change ... of the whole substance") and established the doctrine of concomitance (Christ is "whole and entire" under either species).

Eastern Orthodox and Coptic Orthodox Trajectories: Real Presence as Holy Mystery

• The Eastern Orthodox Church consistently confesses the Eucharist is truly the body and blood of Christ but frames the "how" as a mystery while centring the epiclesis (invocation) as an essential liturgical act.

• Orthodox traditions describe the bread and wine as “mysteries and symbols” of God’s real presence.

• However, Orthodoxy is not merely "anti-transubstantiation"; the 1672 Confession of Dositheus emphatically stated that after consecration, the substance of bread and wine is changed into Christ’s body and blood.

• The Coptic Orthodox Church (Oriental Orthodox) shares a strong confession of real change and presence, preferring mystery-language and a Spirit-centred epiclesis over crude "physical" accounts.

• Coptic tradition views the Eucharist as a “bloodless sacrifice” instituted on Covenant/Maundy Thursday, using leavened bread to serve as the Eucharistic "Lamb".

• Liturgically, Eastern churches differ from the mediaeval Latin West: leavened bread is the Orthodox norm (while Latin law specifies unleavened wheat bread), and Byzantine churches traditionally distribute both elements together, placing them in the communicant's mouth using a spoon.

The Reformation Fracture: Modes of Presence and Sacrifice

• The 16th-century Western church fractured over what the Supper is and what it does, despite agreeing it is a memorial action that deepens communion.

• Martin Luther violently rejected Roman transubstantiation but insisted on the real presence of Christ’s body and blood “in, with, and under” the bread and wine. (While often labelled "consubstantiation", this term is widely considered an unofficial and inaccurate label for Lutheran doctrine).

• The Swiss Reformed movement, led by Ulrich Zwingli, rejected locating Christ’s body in the elements. At the 1529 Marburg Colloquy, Zwingli pushed for a “spiritualist” interpretation against Luther's literal reading, connecting the Eucharist to a spiritual presence appearing to the believer rather than a change in the elements.

• John Calvin represented a middle ground ("real but spiritual presence"), teaching genuine communion with Christ through a spiritual reality rather than corporeal localisation in the bread and wine.

• The English Reformation produced the Thirty-nine Articles, which denied transubstantiation as unscriptural and defined the reception of Christ’s body as “heavenly and spiritual", received through faith.

• In response, the Council of Trent reaffirmed transubstantiation, the “true, real, and substantial” presence, concomitance, and the concept of the Mass as a true, unbloody sacrifice that applies the fruits of the cross for both the living and the dead.
