The preaching of the gospel as a sacramental event is at the heart of Reformation theology. Preaching is also at the heart of Reformation faith—preaching as an indispensable means of grace and a sure sign of the true church. Where is the church? According to Article VII of the Augsburg Confession (1530), the church is that place where the Word is purely preached and the sacraments are duly administered. The Second Helvetic Confession (1566) went even further when it declared that “the preaching of the Word of God is the Word of God.”
Of course, preaching—unlike the printing press—was not a new invention of the Reformation era. Far from it. Think of Augustine and Chrysostom in the early church, Bernard of Clairvaux, John Hus, and the many mendicant friars who fanned out across Europe in the Middle Ages.
St. Francis preached the gospel to a Muslim sultan, and Savonarola declared God’s judgment on the sinful leaders of Florence. Bernardino of Siena, the great Franciscan herald, preached to throngs in the 15th century, calling on his listeners to repent, confess their sins, and go to Mass. The Protestant reformers knew this tradition and built on it, but they also transformed it in two important respects.
Central Act of Worship
First, they made the sermon the centerpiece of the church’s regular worship. Prior to the Reformation, the sermon was mostly an ad hoc event reserved for special occasions or seasons of the liturgical cycle, especially Christmas and Eastertide. Most sermons were preached in town squares or open fields. The reformers brought the sermon back inside the church and gave it an honored place in the public worship of the gathered community. The central role of preaching in Protestant worship can be seen in the way pulpits were raised to a higher elevation as families gathered with their children to hear the Word proclaimed.
Second, the reformers introduced a new theology of preaching. They were concerned that the Bible take deep root in the lives of the people. The Word of God was meant not only to be read, studied, translated, memorized, and meditated on; it was also to be embodied in the life and worship of the church. What might be called the practicing of the Bible—its embodiment—was most clearly expressed in the ministry of preaching. Martin Luther believed that a call to the preaching office was a sacred trust and shouldn’t be used for selfish purposes. “Christ did not establish the ministry of proclamation to provide us with money, property, popularity, honor, or friendship,” he said.
Preachers should be wary of listeners who are too complimentary, for flattery can have a sinister outcome. Puffed-up preachers are likely to think, This you have done; this is your work; you are a first-rate man, the real master. Such conceit is not even worth throwing to the dogs, Luther said. Faithful preachers should teach only God’s Word and seek only his praise. “Likewise, the hearers should also say: ‘I do not believe in my pastor, but he tells me of another Lord whose name is Christ; him he shows me.’”
Preaching was no less important in the Reformed tradition. When one visits the Great Minster Church in Zurich today, the following inscription can be read over the portal: “The Reformation of Huldrych Zwingli began here on January 1, 1519.” That date, no less than October 31, 1517, can answer the question, “When did the Reformation begin?”
For on that first day of January, which happened to be Zwingli’s birthday, the new pastor began his pulpit ministry by announcing his intention to dispense with the prescribed texts of the traditional lectionary. He would follow a new paradigm: preaching expositional sermons, chapter by chapter, starting with the Gospel of Matthew. After completing Matthew, Zwingli resumed the same lectio continua method by taking up Acts, then the letters to Timothy, Galatians, 1 and 2 Peter, Hebrews, the Gospel of John, and the other Pauline letters. He then turned to the Old Testament, beginning with the Psalms, then the Pentateuch and the historical books.
Heinrich Bullinger, who succeeded Zwingli as the Reformation leader in Zurich, reported “a rush of all sorts of people, in particular the common man, to these evangelical sermons of Zwingli’s, in which he praised God the Father, and taught all people to place their trust in God’s Son, Jesus Christ, as the single Savior.” One of those common people who rushed to hear Zwingli in the 1520s was a young student named Thomas Platter. He tells of hearing a sermon by Zwingli that was “expounded so powerfully that I felt as if someone was pulling me up by my hair.”
From the pulpit of St. Pierre in Geneva, John Calvin followed the preaching pattern established by Zwingli. His pulpit work was marked by sequential, text-driven preaching. In the course of his ministry at Geneva, Calvin delivered more than 4,000 sermons, and many have survived for us to study.
What was the secret of Calvin’s preaching? Hughes Oliphant Old gave this answer:
Calvin drew out of the Scriptures aspects of Christian teaching which the church had not heard for centuries. This was above all the case for the doctrine of grace. The promise of salvation was presented to all who would believe it. Calvin preached justification by faith, as all the reformers did. More than some, perhaps, he also preached sanctification by faith. The lives of those who believed the Word of God would be transformed by that Word. Holiness was the fruit of faith. To believe the Word was to live by the Word, and that life lived according to the Word of God was blessed, both in this world and in the world to come.
Three Marks of Reformation Preaching
In an important essay published in Theology Today in 1961, Heiko A. Oberman set forth the distinctive marks of Reformation preaching in terms of three interrelated aspects.
1. The sermon is an apocalyptic event.
Not quite in the sense of Savonarola’s preaching of impending doom to the people of Florence, but in the sense that the sermon unveils and makes present the last judgment here and now. Without demythologizing Christ’s future coming, gospel preaching existentializes the final will of God for every hearer by calling for a decisive response here and now. “In the sermon,” Oberman observed, “Christ and the Devil are revealed, Creator and creature, love and wrath, essence and existence, ‘Yes’ and ‘No.’”
