The Lord's Supper as a Sign of Unity: Eucharistic Ecclesiology and the Unity Creed

The Lord's Supper is simultaneously the most powerful sign of Christian unity and the most contested point of division. Christians who confess the same creed, share the same baptism, and use the same Bible have often refused to share a table because of unresolved eucharistic disagreements. How does the Unity Creed's vision of Christian unity navigate this reality?

The Supper as Eschatological Sign

The Lord's Supper is an eschatological meal — a foretaste of the marriage supper of the Lamb, the final banquet of the kingdom. At the table, Christians anticipate the unity that will be fully realized only when Christ returns and all his people are gathered. This eschatological dimension means that table fellowship carries a weight beyond its immediate occasion: to share the supper is to enact, however imperfectly, the union of all believers in Christ.

Why Eucharistic Division Is Painful

The pain of eucharistic division is proportionate to what the supper signifies. When Christians who are genuinely united in Christ cannot commune together because of ecclesial or doctrinal barriers, they enact a contradiction — the sign of unity becomes a sign of division. Catholic, Orthodox, Lutheran, Reformed, Baptist, and charismatic Christians all celebrate the Lord's Supper, yet rarely together. The table that should unite becomes a boundary marker.

Eucharistic Ecclesiology

Eucharistic ecclesiology — the view that the church is most fully itself in the eucharistic assembly — has been a major theme in twentieth-century ecumenical theology, particularly in Eastern Orthodox and Catholic thought. On this view, to be in eucharistic communion is to be in ecclesial communion. Division at the table reflects and reinforces division in the body. Unity at the table requires, on this account, a visible unity of the church that makes shared communion theologically coherent.

Evangelical Approaches to Eucharistic Unity

Evangelical traditions have typically understood the supper's unifying significance more pneumatologically: all who are spiritually united to Christ by faith are united to each other at the table, regardless of ecclesial structures. Open communion practices — inviting all baptized believers to the table — express this theological conviction. The Unity Creed's vision aligns more closely with this evangelical instinct, locating unity in shared faith rather than in institutional eucharistic communion.

A Goal Worth Pursuing

Whatever one's ecclesiology, the Lord's Supper stands as both a goal and a judgment. As a goal: the Unity Creed envisions a church whose visible unity eventually permits shared eucharistic fellowship across the traditions that are already spiritually one. As a judgment: every excluded table communion is a reminder of how far the church falls short of its own confession. The supper is both a foretaste of what will be and an indictment of what is not yet.
