Martin Luther's famous declaration, "Here I stand. I can do no other. God help me. Amen," is traditionally associated with the Diet of Worms in 1521, where he was called to answer for his teachings before the Holy Roman Emperor and church leaders. Refusing to recant unless convinced by Scripture and sound reason, Luther stood firm in his convictions despite the very real possibility of imprisonment or death.

Four years earlier, in 1517, Luther had challenged the teachings and practices of the Church by publishing his Ninety-five Theses, traditionally believed to have been posted on the door of the Castle Church in Wittenberg. His growing disagreement with church authorities eventually led to his excommunication.

At the heart of Luther's teaching was the conviction that we are saved by God's grace alone, through faith alone, because of Christ alone—not by our own works or merits. He believed that Scripture alone is the final authority for Christian faith and life and that the good news of Jesus Christ should be available to everyone.

Rather than silencing him, Luther's excommunication strengthened his resolve. He continued preaching, teaching, translating the Bible into German so that ordinary people could read God's Word for themselves, and writing extensively. His work ignited the Protestant Reformation and continues to shape Lutheran Christianity and the wider Christian Church today.
