The Book of Concord or Concordia is a compilation of the major theological documents of early Lutheranism. The book was first published on June 25, 1580, fifty years after the presentation of the Augsburg Confession to Emperor Charles V at the Diet of Augsburg. The Book of Concord compiles the important Lutheran confessional documents, that is, documents that summarize and interpret the teachings of the Bible. It was intended to be a definitive Body of Doctrine (Corpus Doctrinae) for all Lutherans. Its editors, Jakob Andreä and Martin Chemnitz, avoided that term in order to distance the Concordia from earlier territorial Corpora Doctrinae.
