Luther Stands Before the Diet of Worms

Summoned to recant before the emperor, a defiant monk instead bound his conscience to Scripture and split Western Christianity.

Verified · City of Worms

On 17 April 1521, the monk Martin Luther was led into the assembly of the Diet of Worms, the imperial council convened by Emperor Charles V. His writings had already provoked a papal condemnation, and he travelled to the Rhineland city under an imperial safe-conduct, uncertain whether it would be honoured.

Inside the bishop’s palace, officials pointed to a stack of his books spread across a table and asked two questions: were these his works, and would he renounce them? Luther acknowledged the books as his own but, sensing the stakes, asked for a day to consider his answer rather than respond on the spot.

“My conscience is captive to the Word of God.”

Returning the next day, he refused to recant unless convinced by Scripture or plain reason. The confrontation hardened the divide between Rome and the emerging Reformation. Weeks later the Edict of Worms branded Luther an outlaw, yet his stand at Worms became a defining moment in the birth of Protestantism and the wider Western religious upheaval.
