The Apology of the Augsburg Confession was formulated by Philip Melanchthon as the response to the Roman Confutation against the Augsburg Confession. Melanchthon was writing a defense of the original Confession, and a refutation of this Confutation that Emperor Charles V had commissioned. Melancthon, in a portrait engraved by Albrecht Dürer, 1526 Philipp Melanchthon (February 16, 1497 - April 19, 1560) was a German theologian and writer of the Protestant Reformation and an associate of Martin Luther. ... The Augsburg Confession, in Latin Confessio Augustana, is the central document of the Lutheran reformation, which was a reaction against the Roman Catholic Church. ...
The second edition, published in September 1531 in Latin is the edition that is most widely recoginzed as the best and includes changes to the original that were suggested by Martin Luther. It is seven times longer than the Augsburg Confession itself.
The AugsburgConfession, also known as the "Augustana" from its Latin name, Confessio Augustana, is the primary confession of faith of the Lutheran Church and one of the most important documents of the Lutheran reformation.
After the reading the confession was signed by the Elector John of Saxony, Margrave George of Brandenburg, Duke Ernest of Luneburg, the Landgrave Philip of Hesse, the Prince Wolfgang of Anhalt, the representatives of Nuremberg and Reutlingen, and probably also by the electoral prince John Frederick and Duke Francis of Luneburg.
The emperor had ordered the confession to be presented to him at the next session, June 24; but when the evangelical princes asked that it be read in public, their petition was refused, and efforts were made to prevent the public reading of the document altogether.
The Apology of the AugsburgConfession was prepared by Philipp Melanchthon as a response to the Roman Catholic "Confutation of the AugsburgConfession" which was written to answer the Lutheran AugsburgConfession after it was presented in 1530 at the Diet of Augsburg.
Melanchthon wrote this as a defense of the original Confession, and a refutation of this Confutation that Emperor Charles V had commissioned.
The Lutheran Church's formal collection of confessions in the Book of Concord refer to the first edition of the Apology when it is quoted in the Solid Declaration of the Formula of Concord.
