Who is known for posting the 95 Theses on the door of a church in Saxony?

The individual recognized for posting the 95 Theses on the door of a church in Saxony is Martin Luther. This pivotal act occurred in 1517 and is often cited as the beginning of the Protestant Reformation. Luther's 95 Theses challenged the practices of the Catholic Church, particularly the sale of indulgences, which he vehemently opposed. His arguments called for a return to biblical teachings and emphasized faith as the means of salvation. Luther's bold move to publicly share his ideas sparked significant debate and ultimately led to the establishment of various Protestant denominations, reshaping the religious landscape of Europe.

The other figures mentioned, while influential in their own right, did not undertake this specific act of posting the theses. John Calvin is known for his role in developing Reformed theology, Henry VIII is notable for his break with the Catholic Church to form the Church of England, and Ulrich Zwingli was a key reformer in Switzerland whose contributions were distinct from Luther’s actions in Germany.
