October 31, 1517

On October 31, 1517, Martin Luther posted 95 theses about Christian faith on the door of a church in Wittenberg, Saxony, and launched the Protestant Reformation. In the document, Luther asserted that salvation was effected by God's grace alone, approached by faith alone. Marty argues that Luther's theses has now become the means of building a bridge for Catholics and Lutherans to work with each other.
