What document did Luther famously nail to the church door in Wittenberg?

Martin Luther famously nailed the 95 Theses to the church door in Wittenberg in 1517 as a public challenge to the practices of the Catholic Church, particularly the sale of indulgences. The document outlined his grievances and sparked significant debate about church practices and theological beliefs during the Reformation. The act of nailing the Theses is often seen as the catalyst that initiated the Protestant Reformation, leading to a fundamental shift in Christianity and the establishment of various Protestant denominations.

The other options represent important events or documents in history but are not directly related to Luther's actions in Wittenberg. The Council of Trent was a major Catholic response to the Reformation that took place later, the Act of Supremacy declared the English monarch as the head of the Church of England, and the Diet of Worms was an assembly in which Luther defended his ideas but did not involve him nailing any document to a church door. Understanding the context and implications of the 95 Theses helps illustrate its significance in the broader scope of religious history.
