abstract:Formula of Concord (1577) (German, Konkordienformel; Latin, Formula concordiae; also the "Bergic Book" or the "Bergen Book") is an authoritative Lutheran statement of faith (called a confession, creed, or "symbol") that, in its two parts (Epitome and Solid Declaration), makes up the final section of the Lutheran Corpus Doctrinae or Body of Doctrine, known as the Book of Concord (most references to these texts are to the original edition of 1580). The Epitome is a brief and concise presentation of the Formula's twelve articles; the Solid Declaration a detailed exposition.
