Martin Luther 2025, also known as the Luther Decade, commemorates the 500th anniversary of the start of the Protestant Reformation, which is traditionally dated to 1517 when Martin Luther posted his Ninety-Five Theses. The anniversary will be observed from 2023 to 2025, culminating in 2025, which marks the 500th anniversary of Luther’s death.
The Reformation was a major religious movement that led to the establishment of Protestantism, which has had a profound impact on Western Christianity and the world. Luther’s ideas about salvation by faith alone, the priesthood of all believers, and the authority of Scripture over tradition challenged the authority of the Catholic Church and led to the establishment of new Protestant denominations.
