Five hundred years ago, a lowly German priest walked up to the church door in Wittenberg and posted a document that altered the course of history. It has now been five centuries since Martin Luther stood up and confronted Roman Catholicism. The kindling had been laid over decades, and Luther’s little, almost accidental spark soon set all of Europe ablaze.

In time, this lowly monk proved he had what it took to hold his ground against the Church and the world — and under God, he became the tip of the spear for massive reform. In one especially memorable scene, he stood before the emperor and declared courageously, risking his own life, “Here I stand. I can do no other. So help me, God.”

But Luther did not stand alone. The Reformation was not about one or two big names — Luther, Calvin, Zwingli — but about a massive movement of Christian conviction, boldness, and joy that cost many men and women their lives — and scattered the seeds that are still bearing fruit in the twenty-first century. Not only was Luther surrounded by many Reformers in Germany, but lesser-known heroes of the faith rose up all over Europe. Heroes like Heinrich Bullinger, Hugh Latimer, Lady Jane Grey, Theodere Beza, and Johannes Oecolampadius. Luther was the battering ram, but he ignited, and stood with, a chorus of world changers.

And here we stand today, 500 years later. Luther wasn’t alone then, and he’s not alone now. To mark the 500th anniversary, we produced a 31-day journey of short biographies of the many heroes of the Reformation, just 5–7 minutes each day.
