On the Lord's Supper

Zwingli's treatise on the Lord's Supper emerged from the heated sacramental controversies that divided the Protestant Reformation in the 1520s. Written in 1526, this work represents the Zurich reformer's mature position against both Catholic transubstantiation and Lutheran consubstantiation, articulated in the midst of increasingly bitter disputes with Martin Luther over the nature of Christ's presence in communion. The treatise served as Zwingli's theological foundation heading into the failed Marburg Colloquy of 1529, where the sacramental question would prove the insurmountable barrier to Protestant unity.

Zwingli argues that the Lord's Supper is fundamentally a memorial and symbolic act rather than a means of grace that conveys Christ's body and blood. He insists that Christ's physical body, having ascended to heaven, cannot be literally present in the bread and wine, and that Jesus's words "this is my body" must be understood figuratively—as "this signifies my body." The treatise develops a sophisticated theology of sign and symbol, contending that the sacrament's power lies not in any physical transformation but in the faith of the believer and the community's act of remembrance. Zwingli emphasizes the Lord's Supper as a public confession of faith and a visible sign of church membership, while rejecting any notion that the elements themselves convey spiritual benefit to the recipient.

This treatise established the memorial view of communion that would profoundly influence Reformed theology and numerous Protestant traditions. Zwingli's symbolic interpretation became foundational for later Reformed confessions and continues to shape sacramental practice in many Presbyterian, Reformed, and Baptist churches today. Who should read this: theologians and church historians studying Reformation sacramental debates, pastors in Reformed traditions seeking to understand their communion theology, and anyone interested in how fundamental disagreements over the Lord's Supper fractured early Protestant unity. This is not recommended for readers seeking devotional material or practical guidance for communion services.
