The document provides background information on Martin Luther and the Protestant Reformation. It discusses Luther's life and religious experiences that led him to question the Catholic Church's teachings on indulgences. In 1517, Luther published his 95 Theses criticizing indulgences, which helped spark the Protestant Reformation. The Reformation established doctrines such as salvation by grace alone through faith alone in Christ alone according to Scripture alone, for the glory of God alone. Reformation Sunday commemorates these theological changes and emphasizes the need for continual religious reform and revival.
