1530 primary confession of faith of the Lutheran tradition
The Augsburg Confession, also known as the Augustan Confession or 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 Protestant Reformation. The Augsburg Confession was written in both German and Latin and was presented by a number of German rulers and free-cities at the Diet of Augsburg on 25 June 1530.
