After Luther’s death, his followers fell into theological disputes. On 25 June 1580, the fiftieth anniversary of the Augsburg Confession, the Konkordienbuch, the Book of Concord, appeared in Dresden in German. It already carried many signatures. As a body of doctrine, it was to give the Lutheran church a binding basis of faith. An earlier collection by Melanchthon from 1558 had not won general acceptance. Today, some Lutheran churches in Germany still name these writings as binding, and their pastors must commit to them at their ordination.
