Christ's Presence in the Eucharist

This Sunday we’ll be hearing a message on communion - so I thought I’d share a paper I wrote a few years on ‘The nature of Christ's presence in the Lord’s Supper’. You can access it here:

Bread, Wine, and the Mystery of Presence: Zwingli vs. Calvin on the Eucharist

The nature of Christ’s presence in the Lord’s Supper has been a subject of fierce debate for centuries, dividing theologians throughout the patristic, medieval, and Reformation periods. At the heart of the controversy is a single question: should Jesus’ words, "This is my body," be understood literally or figuratively?.

While early figures like Thomas Aquinas argued for transubstantiation—the belief that the bread and wine literally become Christ's body and blood—the Reformation brought new perspectives that moved away from Roman Catholic dogma. Two of the most influential voices in this shift were Huldrych Zwingli and John Calvin.

Huldrych Zwingli: The Power of the Sign

Zwingli radically rejected the idea of a physical presence in the elements. He argued that the word "is" in "This is my body" was meant metaphorically, pointing to the symbolic significance of the meal rather than a literal transformation.

For Zwingli, Christ’s physical body remains in heaven following the Ascension. Therefore, the bread and wine are signs or ceremonials—human instruments used by believers to publicly declare their faith in what Christ has already accomplished. He was wary of any theology that suggested the sacrament had power to produce saving faith, as he believed this would diminish Christ’s once-for-all sacrifice on the cross. In his view, the "eating" is a spiritual act of faith, and the elements themselves are "empty signs of remembrance".

John Calvin: The Spiritual Ladder

John Calvin sought a "middle course" between the literalism of the past and Zwingli’s purely symbolic view. While he agreed with Zwingli that Christ’s physical body is in heaven, he disagreed that Christ was therefore absent from the meal.

Calvin’s theology of the Eucharist emphasizes a mystical and spiritual participation. He believed the bread and wine do not just signify Christ’s body and blood but actually "confer what they signify". In Calvin’s view, the Lord’s Supper is a "divine instrument" or a "ladder" by which believers are raised to heaven through the power of the Holy Spirit to feed on Christ.

For Calvin, the Eucharist is:

• A means of grace providing spiritual nourishment.

• A spiritual communication where the Holy Spirit bridges the gap between heaven and earth.

• A way for Christ to be "always present to those who are his... just as if he were present in the body".

Why It Matters

While both Reformers rejected transubstantiation, their difference lies in the richness of the presence. Zwingli focused on Christ’s physical absence to protect the doctrine of the Ascension, often reducing the sacrament to a memorial sign. Calvin, however, emphasised the pneumatological (Spirit-led) dimension, arguing that the Holy Spirit makes a true communion with Christ possible during the meal.

Ultimately, Calvin’s view offers a more profound sense of mystery, suggesting that through the bread and wine, we don't just remember a past event—we truly encounter and are nourished by the living Christ.

I hope to see you Sunday where we will be taking communion and getting nourished by the living Christ :)
