The Augsburg Confession is the first and most fundamental Confession of the Lutheran Church. It was composed for a public reading at the Diet of Augsburg on June 25, 1530. Although written by Melanchthon, it was presented as the official answer of the undersigned German princes to the summons of Emperor Charles V. Two copies were presented on the same day, one in German, the other in Latin. This work translates a conflation of the German and Latin texts and was prepared for the Concordia Triglotta of 1921.
