This is Reformation Sunday, the 500th anniversary of the Protestant Reformation, set off by Martin Luther posting his 95 Theses on door of All Saints’ Church in Wittenberg on October 31st, 1517. The Reformation was a movement to reform the Church from some abuses that had taken hold in the late Middle Ages, and not a revolution to start a new church. The Reformers went back to Scripture and what the Church taught over the centuries.
