Zwingli and the Swiss Reformation

Historical Theology

Historical Setting

While Luther wrestled in Saxony, a parallel reform was rising in the Swiss Confederation, and it would become the headwaters of the Reformed tradition. Its first great figure was Huldrych Zwingli (1484–1531), born in the Toggenburg valley, schooled in the humanism of Erasmus, and steeped in the Greek New Testament. Unlike Luther, Zwingli came to the gospel less through a tortured conscience than through patient study of the text. By his own account he was preaching the plain meaning of Scripture before he had read much of Luther, and he resented the suggestion that he was merely a Lutheran echo.

In 1519 he became people’s priest at the Grossmünster in Zurich and began an audacious experiment: instead of preaching the appointed lectionary, he preached straight through the books of the Bible, beginning with Matthew. The reform of a whole city grew from that pulpit.

What Was at Stake

Two things were at stake in Zurich. The first was the principle of reform itself: was the church to retain whatever Scripture did not forbid, or to require positive warrant from Scripture for its worship and practice? Zwingli pressed the stricter, more thorough principle — what Scripture does not command in worship is not to be imposed — and this Reformed instinct would shape Geneva, Scotland, and the Puritans after him.

The second was the nature of the Lord’s Supper, the question that would divide the evangelical movement against itself. Here even brothers in the gospel could not agree, and the fracture has never fully healed.

Key Players

Huldrych Zwingli, the Zurich reformer, scholar, and eventually soldier-chaplain.

The Zurich City Council, which sponsored public disputations (1523) and enacted reform by civic authority — clearing images, abolishing the Mass, and ending clerical celibacy.

Martin Luther and Philipp Melanchthon, the Wittenberg party at the great colloquy.

Philip of Hesse, the German prince who convened the Marburg Colloquy (1529) in hopes of uniting Protestants into a single political and theological front against the Emperor.

Heinrich Bullinger, Zwingli’s successor, who consolidated the Zurich reform and bequeathed the Second Helvetic Confession.

The Outcome

By the mid-1520s Zurich was a reformed city: the Mass abolished, images removed, the monasteries repurposed for charity and schooling, worship simplified to the Word, prayer, and psalmody.

Then came Marburg. Philip of Hesse brought Luther and Zwingli together in October 1529, and on fourteen of fifteen articles they agreed. The fifteenth was the Supper. State both sides fairly. Luther, reading “This is my body” with stubborn literalism, insisted on the true bodily presence of Christ — in, with, and under the bread — received by the mouth even of unbelievers; to deny it seemed to him to deny the plain Word of Christ and the comfort of the sacrament. Zwingli, reading “is” as “signifies” (as in “I am the door”), held that the bread and wine are signs that direct faith to the once-crucified Christ; the Supper is a memorial and a public pledge of the believing community, and Christ’s body, now ascended, is in heaven, not on a thousand altars. Each feared the other’s view dishonored Christ — Luther that Zwingli emptied the sacrament, Zwingli that Luther bound the infinite Christ to bread. Luther chalked Hoc est corpus meum on the table and would not move. The colloquy ended in fellowship withheld; Luther reportedly said, “You have a different spirit.”

Two years later, Zwingli fell at the Battle of Kappel (1531), cut down as a chaplain among the Zurich troops in a war between Catholic and Protestant cantons. He was forty-seven. His death, sword in the field, has always troubled those who admire him.

Scriptural Grounding

The disputed texts were the words of institution.

“And he took bread, and when he had given thanks, he broke it and gave it to them, saying, ‘This is my body, which is given for you. Do this in remembrance of me.’” (Luke 22:19)

Zwingli leaned on Christ’s own figurative speech and on the ascension:

“I am the true vine.” (John 15:1); “I am the door.” (John 10:9)

“Why do you seek the living among the dead? He is not here, but has risen.” (Luke 24:5–6)

“This Jesus… will come in the same way as you saw him go into heaven.” (Acts 1:11)

Doctrinal Significance

Zwingli’s lasting gift was twofold. First, he gave the Reformed wing its method: reform governed strictly by Scripture, especially in worship — the seed of what we call the regulative principle. Second, he forced the eucharistic question that Calvin would later answer more richly. For Zwingli’s memorialism, while a needed corrective to a magical view of the Supper, risked making the sacrament a bare sign — a mere reminder, with the believer doing all the remembering and Christ doing nothing. The mature Reformed position, framed by Calvin and confessed at Westminster, would hold a middle ground: not a bodily presence, but a real spiritual feeding on Christ by faith through the Spirit.

“Worthy receivers… do then also inwardly by faith, really and indeed, yet not carnally and corporally, but spiritually, receive and feed upon Christ crucified.” (WCF 29.7)

A Reformed Assessment — Wheat and Chaff

The wheat is substantial. Zwingli recovered the centrality of preaching, purified worship of accumulated superstition, and rightly denied the carnal presence and the sacrifice of the Mass. He is a true father of our tradition.

The chaff we name honestly. His view of the Supper, taken alone, was too thin; the Reformed churches refined rather than simply adopted it. His easy fusion of church reform with the power of the city council, and his death in arms at Kappel, expose the era’s confusion of the gospel’s spiritual weapons with the magistrate’s sword — a confusion the New Testament does not sanction. We honor the reformer while declining to follow him onto the battlefield.

Lessons for Today

Zwingli teaches that consecutive, expository preaching of whole books can reform a congregation more deeply than any program. He teaches that worship is to be governed by the Word, not by taste or tradition. And his hardest lesson is cautionary: gospel zeal must never reach for the sword, and good men can divide over the Table at which they ought most to be one. We mourn the breach at Marburg as a wound in Christ’s body, and we labor and pray for the unity that eluded our fathers.
