What are the Augsburg Confession and the Apology (Defense) of the Augsburg Confession?
In the year 1530, the Lutherans were required to present their confession of faith before the emperor in Augsburg, Germany. Philip Melanchthon wrote the Augsburg Confession and it was read before the imperial court on June 30, 1530. One year later, the Lutherans presented their defense of the Augsburg Confession, which is what “apology” here means. It too was written by Philip Melanchthon. The largest document in the Book of Concord, its longest chapter, is devoted to the most important truth of the Christian faith: the doctrine of justification by grace alone, through faith alone, in Christ alone.
