The Controversies the Formula of Concord Resolved

When Martin Luther died in 1546, the Lutheran movement lost its unifying center. Within a decade, theologians who all claimed Luther's legacy were fighting each other with the same ferocity they had once directed at Rome. The disputes were not minor. They touched the heart of the Gospel: What saves? What role does law play in the Christian life? Is Christ truly present in the Supper? After thirty years of controversy, a group of Lutheran theologians produced the Formula of Concord (1577) to answer these questions definitively.

The Adiaphoristic Controversy

The first controversy was political. After defeating the Lutheran princes at the Battle of Mühlberg (1547), Emperor Charles V imposed the Augsburg Interim — a temporary religious settlement that restored many Catholic practices. Some Lutheran theologians, led by Melanchthon, agreed to accept these restored practices as 'adiaphora' (indifferent matters). Others, led by Matthias Flacius, argued that in a time of confession, nothing is indifferent: conceding liturgical forms under compulsion is a denial of the Gospel. The Formula sided with Flacius: in times of persecution and false witness, ceremonies are not neutral.

The Antinomian Controversy

Some theologians argued that the law has no place in Christian proclamation — that repentance should be produced by the Gospel alone, not by the law's condemnation of sin. The Formula (Article V) rejected this: the law must be preached to produce genuine contrition. Without the law's accusation, the Gospel's forgiveness has nothing to forgive. The law and Gospel must be distinguished, but both must be preached.

The Majoristic Controversy

Georg Major taught that good works are necessary for salvation. His opponents — reacting against perceived compromise — said good works are actually detrimental to salvation. The Formula rejected both extremes: good works are not necessary for salvation, nor are they detrimental. They are the necessary fruit of faith, but they are not the basis of standing before God.

The Lord's Supper Controversy

The most bitter dispute was over the Lord's Supper. Luther had insisted that Christ's body and blood are truly present in, with, and under the bread and wine (the 'sacramental union'). Zwingli held that the Supper is a memorial and Christ is present only spiritually. The Marburg Colloquy (1529) ended in failure: Luther and Zwingli could not agree. After Luther's death, some Lutherans moved toward Calvin's 'spiritual presence' view. The Formula (Article VII) definitively rejected this, reaffirming Luther's position: the body and blood of Christ are truly and substantially present.

Predestination and Election

The Formula's final article (XI) addressed election. Against those who taught that God predestines some to damnation (double predestination), the Formula teaches that God elects to salvation 'in Christ' — solely for the sake of Christ and through the means of grace. Damnation is the result of human rejection, not divine decree. God genuinely desires all to be saved; the means of grace are the place where election is certain.

Why the Controversies Still Matter

The Formula of Concord is not merely a historical settlement. The questions it addressed — about law and Gospel, free will and grace, the real presence, and election — are perennial. Every generation faces some version of them. The Formula endures because it understood that getting these questions wrong corrupts the proclamation of the Gospel, and getting them right sets the conscience free. For the standard scholarly history and theology of the Book of Concord, Kolb and Nestingen's survey traces these controversies with both historical depth and confessional clarity.
