The Real Presence: What Happens at Communion?

The Question

What happens at the table?

• Jesus took bread and said, “This is my body.”
• Ever since, Christians have asked what those words mean.
• Is the bread changed, a vivid sign, or something in between?
• The answers mark some of the deepest divisions in the church.

Key idea: Nearly all historic churches affirm that Christ is present at Communion; they differ on the manner of that presence.

Key Terms

The vocabulary of the meal

• “Eucharist” means thanksgiving; “Communion” means sharing.
• “Real presence” affirms that Christ himself is truly given.
• “Substance” is what a thing is; “accidents” are how it appears.
• A “sacrament” is an outward sign of an inward grace.

Useful fact: The substance-and-accidents language comes from Aristotle, later used by Aquinas to explain the change.

Roots

From upper room to council hall

• Early Christians spoke of the bread and cup in strikingly realist terms.
• For centuries the “how” was left largely unexplained.
• Medieval scholars later pressed for a precise account.
• In 1215 the Fourth Lateran Council adopted the word “transubstantiation.”

Catholic View

Transubstantiation

• Catholics teach that the whole substance of the bread and wine becomes Christ’s body and blood.
• The appearances — taste, look, and texture — remain unchanged.
• Aquinas explained this with substance-and-accidents language.
• The Council of Trent defined it as dogma in 1551.

Key idea: For Catholics the change is real and complete: what looks like bread is truly Christ’s body, though it still appears as bread.

Lutheran View

In, with, and under

• Luther affirmed Christ’s true body and blood in the Supper.
• But he denied that the bread stops being bread.
• Christ is present “in, with, and under” the bread and wine.
• He held this firmly against Zwingli at Marburg in 1529.

Useful fact: Lutherans usually reject the label “consubstantiation,” preferring to call it a sacramental union they do not try to fully explain.

Reformed View

Truly received by the Spirit

• Calvin taught a real but spiritual presence in the Supper.
• Believers truly feed on Christ, yet by the Holy Spirit.
• The faithful are lifted up to commune with the ascended Christ.
• This is far more than a memory, though the bread itself is unchanged.

Key idea: For the Reformed, Christ is genuinely given and received by faith — a real presence effected by the Spirit rather than a change of substance.

Memorialist View

Do this in remembrance

• Zwingli emphasized the Supper as a memorial of Christ’s death.
• The bread and cup are powerful signs that point beyond themselves.
• The gathered church remembers and proclaims until he comes.
• Many Baptists and evangelicals hold this remembrance view.

Useful fact: The memorialist view is one wing of Protestantism, not the whole of it, and centers on Jesus’ command, “Do this in remembrance of me.”

The East

A holy mystery

• The Orthodox firmly affirm that the gifts truly become Christ’s body and blood.
• But they decline to pin down the “how” in scholastic terms.
• The change is confessed and adored as a genuine mystery.
• Reverence, more than explanation, marks the Eastern approach.

Key idea: The Orthodox affirm a real change as strongly as Rome, yet generally resist defining the mechanism, guarding it as holy mystery.

The Tension

The weight of four words

• “This is my body” can be heard as identity or as symbol.
• In John 6 Jesus speaks of eating his flesh and drinking his blood.
• Paul warns against failing to “discern the body” at the table.
• Each tradition weighs these texts in its own faithful way.

Useful fact: Much of the debate rests on how literally to hear Jesus’ words, “This is my body.”

Misconception

“Protestants deny the real presence”

• It is often said that Protestants reject any real presence.
• But Lutherans and the Reformed strongly affirm one.
• Only the memorialist wing sees the meal as purely symbolic.
• The Reformation divided over how Christ is present, not merely whether.

Misconception: “All Protestants think Communion is just a symbol.” Lutheran and Reformed churches affirm a real presence; only part of Protestantism is purely memorialist.

Why It Matters

The table that both unites and divides

• The Supper is meant to be the church’s deepest sign of unity.
• Yet differing beliefs about it keep many from sharing one table.
• Behind the debate lies a shared longing to receive Christ rightly.
• Understanding each view fairly is a step toward that unity.

In Sum

One table, several doors

• Catholics, Orthodox, Lutherans, and Reformed all confess a real presence.
• They picture the manner differently — change, union, or Spirit.
• Memorialists receive the meal as a treasured remembrance.
• All gather at Christ’s command to proclaim his death.

In one line: Christians agree that Christ meets his people at the table; they differ on how — from a change of substance, to a Spirit-given presence, to a sacred remembrance.
