On October 31, 1517, a German monk named Martin Luther publicly protested what he considered to be profound abuses in the Roman Church by posting a list of his objections to the church door in Wittenberg. Nailing matters like these on the church door was a customary way of initiating debate in that time and place. Despite the common practice, though, those 95 Theses were no ordinary bulletin board material. Luther was calling into question deeply rooted practices in the medieval church—the paying of indulgences to buy loved ones out of purgatory, the assumption that the pope’s mediation was necessary for Christians to experience the grace of Christ, and the emphasis on deeds performed as a way of earning one’s way into God’s mercy. Dissatisfaction in the church over these practices and others had simmered for centuries in the medieval church, but in the 16th century Luther’s 95 Theses became a flashpoint for reform, igniting revolutionary changes in the Christian Church all across Europe—turning the Church upside down.
From that revolution was born Lutheran Churches, Calvinist Churches, Anglican Churches, and eventually Methodists, Mennonites, Baptists, and others. From that revolution also emerged a Roman Catholic Church that was significantly different than the one from which Luther broke. Reformation Sunday—this year on October 29—annually celebrates the richness of Christian pluralism and the beginning of Christianity’s entrance into modernity. Reformation Sunday also reminds us of some of the fundamental theological convictions for which our Protestant ancestors labored so mightily. In an age in which most American Protestants struggle to define Protestant identity as anything beyond being generically “American,” it seems good to reserve a day each year to think intentionally about our Reformation inheritance. And it’s especially appropriate this year, as we commemorate the five hundredth anniversary of the 95 Theses. Here, then, are seven examples of the theological legacy of the Reformers.
