From forerunners and reformers to families, confessions, and the Five Solas — with an honest look at the hard parts.

Note

This map is simplified. The gold lines trace the movement's connected spine — forerunners into the spark, the spark into the reformers — while the Solas, confessions, and events sit in their own labelled bands.

Dates mark turning points, not clean beginnings. Where a detail is traditional or contested, the card says so.

    Salvation is a gift of God’s grace, not something we earn or deserve.

  • Solus Christus Christ alone · A Reformation watchword

    Christ alone is the mediator between God and humanity; salvation comes through his work.

  • Soli Deo Gloria glory to God alone · A Reformation watchword

    All glory belongs to God alone.

    The influential Reformed confession produced by the Westminster Assembly during the English Civil War era.

Key Events & Aftermath 1524–1672

  • The Peasants’ War 1524–25 · German lands

    A vast peasant uprising, partly stirred by reform ideas; Luther condemned it fiercely, and it was crushed with great bloodshed.

  • The Marburg Colloquy 1529 · Marburg (Germany)

    A meeting to unite Luther and Zwingli; they agreed on 14 of 15 articles but split over the Lord’s Supper.

  • The Münster Rebellion 1534–35 · Münster, Westphalia

    Apocalyptic radicals seized the city of Münster and proclaimed a “New Jerusalem,” until a siege crushed it in 1535.

    The Catholic Church’s own reforming council and its formal answer to the Reformation — the Counter-Reformation.

  • The Peace of Augsburg 1555 · The Holy Roman Empire

    A settlement letting each German prince choose Lutheran or Catholic for his territory — “cuius regio, eius religio.”

  • The Patriarch and the Lutherans 1573–1581 · Tübingen and Constantinople

  • Cyril Lucaris and the Synod of Jerusalem 1629–1672 · Constantinople and Jerusalem

    A Calvinist-leaning confession published in the name of the Patriarch of Constantinople (1629) led Orthodox councils to define their faith against it, most fully at Jerusalem in 1672.

An honest reckoning

  • Luther’s Writings Against the Jews 1543 · Saxony (Germany)

    Late in life Luther wrote vicious antisemitic tracts, including On the Jews and Their Lies (1543). We name this plainly; it cannot be excused.

  • Anabaptists Killed by Fellow Protestants 1520s onward · Central Europe

    Anabaptists were hunted, imprisoned, and executed — not only by Catholics but by fellow Protestants, including in Reformed Zurich.

  • The Peasants’ War and Luther’s Fury 1525 · German lands

    When the peasants revolted, Luther urged the princes to crush them without mercy — a response many find indefensible.

  • A Table Divided from 1529 · Protestant Europe

    Protestants split — bitterly and lastingly — over the meaning of the Lord’s Supper, fracturing their unity from the start.

  • The Wars of Religion 16th–17th c. · Europe

    For over a century, Catholics and Protestants — and Protestants against each other — waged devastating wars, ending in the Thirty Years’ War.
