The Festival of the Reformation

Observed · The Eternal Gospel Proclaimed to Every Nation

One-year lectionary  ·  Revelation 14:6–7  ·  Romans 3:19–28  ·  Matthew 11:12–19

On October 31, 1517, an Augustinian monk and university professor posted Ninety-Five Theses on the door of the Castle Church in Wittenberg. He was not founding a church; he was calling for an academic debate about repentance and the sale of indulgences. The debate escaped the university, Luther was excommunicated, and the confession he could not stop making, that a sinner is justified by grace alone through faith alone in Christ alone, reshaped Europe. The festival itself was standardized only in 1667, when Elector John George II of Saxony declared October 31 an annual festival of the church. The color is red, the color of the Spirit’s fire and of those who confess under fire. When the day falls midweek it is transferred to the nearest Sunday, at a cost: that Sunday’s propers are lost. This is not a contest between churches. It is the celebration of the freedom of the Gospel and the confession of Christ and His Word.

The shape of the service

Introit. Psalm 119:46, “I will speak of your testimonies before kings, and shall not be put to shame.”

Gradual and Verse. The Gradual walks the walls of Psalm 48, and the Verse from Hebrews 12 sets us in a great cloud of witnesses, looking to Jesus.

The Angel and the Reformer. Lutherans have long seen Luther in the angel of Revelation 14, sent to proclaim the eternal Gospel when preaching had grown dark, and Andreas Osiander called him a “third Elijah.” Luther himself, in 1522, wrote that his spirit “cannot accommodate itself” to Revelation, and only by 1530 did he call the book a great comfort to Christians.

Color. Red, the color of the Spirit’s fire and of bold confession under fire.

The readings at a glance

First Reading
Revelation 14:6–7

The angel flies “in mid-heaven” (mesouranema), the zenith where the sun stands at noon, which in Revelation is the pulpit reserved for proclamations no one on earth can miss. John announces the true one against the pagan astronomy of his first hearers. What the angel carries is an “eternal Gospel” (euangelion aionion), and yet its content is “the hour of His judgment has come.” That is not a contradiction but the sharpest Law and Gospel in Scripture: to the beast and those who bear his mark this word is doom; to the persecuted Church the fall of the beast is rescue.

Three verbs follow. Fear God, which is not terror that flees but contrition that runs to the mercy seat; give Him glory, which adds nothing to God but confesses what He has done; worship Him as Creator. Note the last item in the list of what He made: “the springs of waters” (pegai hydaton), where the early Church heard Baptism, the Spirit hovering over water to make a new creation.

Epistle
Romans 3:19–28

This is the passage that broke a monk and remade the Church. Paul first closes the courtroom: the Law speaks “so that every mouth may be stopped” (phrage, from a verb meaning to plug or fence in), the defendant left literally without a defense (anapologetos). No one is justified by works of the Law; the Law’s work is to accuse. Then two words turn history: nyni de, “but now.” Melanchthon called what follows the thesis of the whole letter. The “righteousness of God” (dikaiosyne theou) was the phrase Luther hated, having been taught it meant the justice by which God punishes; when he saw it was righteousness God gives, he said the gates of paradise opened.

The verb dikaioo is a courtroom word: God declares the guilty righteous on the basis of another’s obedience. Paul then stacks two great images. Redemption (apolytrosis) is the slave market and the Exodus, a ransom paid to set captives free. Propitiation (hilasterion) is the golden lid of the ark, the mercy seat where the high priest sprinkled blood on the Day of Atonement. God provides the sacrifice and God receives it. So boasting is not merely discouraged; it is locked out, excluded by a different system altogether, the “law of faith.”

Holy Gospel
Matthew 11:12–19

Verse 12 has been called the greatest riddle in the Synoptics. Is the kingdom “forcefully advancing,” or is it “violently attacked”? The Greek biazetai can be read either way, but outside the New Testament the verb is nearly always hostile. Karlstadt in 1521 read it as the hostility Jesus met; Melanchthon was the first to insist on the triumphant reading. The cruciform sense fits the day: the kingdom comes hidden under weakness, the Baptist in prison and the King bound for a cross. Then Jesus quotes Malachi 3:1 and quietly changes it. Malachi has Yahweh say “prepare the way before Me”; Jesus says “prepare Your way before Your face,” putting Himself where Yahweh stood.

Finally the marketplace children, who are not John and Jesus but this generation, brats who insist the music be theirs: John fasts and has a demon, Jesus feasts and is a drunkard. They rejected the Law through one and the Gospel through the other. The closing line is irony: Wisdom, they ruled, is acquitted of any association with such works. The believer knows those works are the Wisdom of God.

The hymns and their stories

Opening Hymn
“Come, Holy Ghost, God and Lord”  ·  LSB 497
Luther did not write the first stanza of this hymn, and he said so in the strongest terms available to him: “The hymn ‘Come, Holy Spirit Lord and God’ was composed by the Holy Ghost himself, both words and music.” The stanza was already an old German folk verse by the fifteenth century, and rather than replace it he added two stanzas of his own in 1524 and left the original untouched. The melody comes from the plainsong of the Latin antiphon; Reformation musicians squared it off so a whole congregation could carry it. The English text is credited to Catherine Winkworth, which is generous to the point of inaccuracy: she supplied about three lines, Richard Massie roughly a third, and August Crull stitched the whole together for an 1879 school hymnal.
Sermon Hymn
“O God, Our Lord, Thy Holy Word”  ·  see back cover
This chorale, O Herre Gott, dein göttlich Wort, first appeared in the Erfurt Enchiridion of 1527, and for centuries its author was known only by the initials A.H.Z.W. Hymnologists eventually decoded them: Anarg Heinrich zu Wildenfels, born around 1490, a nobleman and court administrator who helped bring the Reformation into Saxony and served as one of its principal supporters at the court of Elector John. The hymn is Reformation theology in miniature: it gives thanks that the Word, “long a hidden treasure” buried under human tradition, has been restored in full measure, insists that salvation is free through faith in Christ alone, and grants plainly that foes will try to overthrow that Word while promising that the truth outlasts them all.
Preparation Hymn
“To God the Holy Spirit Let Us Pray”  ·  LSB 768
The first stanza is medieval, a German Leise ending in the cry Kyrieleis, and it was already old and familiar when the Franciscan preacher Berthold of Regensburg quoted it in a sermon around the middle of the thirteenth century: “It is in truth a useful and dear hymn, and the more you sing it, the better.” The stanza calls the Christian life a journey ending in a faithful death, a hard, literal weight for singers in the many German towns whose hospitals were dedicated to the Holy Spirit. Luther would not change a word of it. He held it up in 1523 as the model for new poets, added three stanzas of his own in 1524, and in 1526 directed that it be sung before the Gospel.
Hymn of the Day
“A Mighty Fortress Is Our God”  ·  LSB 656
It was written between 1527 and 1529, while plague swept Wittenberg, Luther himself fell dangerously ill, Turkish armies pressed the borders, and attacks came from every theological direction. We call it the battle hymn of the Reformation, but that phrase was coined in Basel in 1850; an Augsburg broadsheet of 1529 called it what it was to the people who first sang it: “a hymn of comfort.” Psalm 46 supplies the opening line, and then the devil walks in, though he is never mentioned in the psalm. Gustavus Adolphus had it played on trumpets and kettledrums before Lützen in 1632. Never stop after stanza one, where the devil is still winning.
