The Book of Concord or Concordia (1580) is the historic doctrinal standard of the Lutheran Church,
consisting of ten credal documents recognized as authoritative in Lutheranism since the 16th century. They are also known as the symbolical books of the Evangelical Lutheran Church. The Book of Concord was published in German on June 25, 1580 in Dresden, the fiftieth anniversary of the presentation of the Augsburg Confession to Emperor Charles V at the Diet of Augsburg. The authoritative Latin edition was published in 1584 in Leipzig. Those who accept it as their doctrinal standard recognize it to be a faithful exposition of the Bible. The Holy Scriptures are set forth in The Book of Concord to be the sole, divine source and norm of all Christian doctrine.
The Book of Concord was compiled by a group of theologians led by Jakob Andreae and Martin Chemnitz at the behest of their rulers, who desired an end to the religious controversies in their territories that arose among Lutherans after the death of Martin Luther in 1546. It was intended to replace German territorial collections of doctrinal statements, known as corpora doctrinæ (bodies of doctrine) like the Corpus doctrinæ Philippicum or Misnicum. This aim is reflected by the compilers' not calling it a corpus doctrinæ although it technically is one. The list of writings predating the Formula of Concord that would be included in The Book of Concord are listed and described in the "Rule and Norm" section of the Formula.
Following the preface written by Andreae and Chemnitz (1578–80) the "Three Ecumenical Creeds" were placed at the beginning in order to show the identity of Lutheran teaching with that of the ancient Christian church. These creeds were the Apostles' Creed, Nicene Creed, and Athanasian Creed, which were formulated before the East-West Schism of 1054, but the Nicene Creed is the western version containing the filioque.
The other documents come from the earliest years of the Lutheran Reformation (1529–77). They are the Augsburg Confession, the Apology of the Augsburg Confession, both by Philipp Melanchthon, the Small and Large Catechisms of Martin Luther, his Smalcald Articles, Melanchthon'sTreatise on the Power and Primacy of the Pope, and the Formula of Concord, which was composed shortly before the publishing of the Book of Concord and intended for the same purpose: the pacification and unification of the growing Lutheran movement. The preface of the Book of Concord was considered to be the preface of the Formula of Concord as well.
