The Book of Concord contains documents which Christians from the fourth to the 16th century A.D. explained what they believed and taught on the basis of the Holy Scriptures. It includes, first, the three creeds which originated in the ancient church, the Apostles' Creed, the Nicene Creed, and the Athanasian Creed. It contains, secondly, the Reformation writings known as the Augsburg Confession, the Apology of the Augsburg Confession, the Smalcald Articles, the Treatise on the Power and Primacy of the Pope, Luther's Small and Large Catechisms, and the Formula of Concord.
The Catechisms and the Smalcald Articles came from the pen of Martin Luther; the Augsburg Confession, its Apology, and the Treatise were written by Luther's co-worker, the scholarly Phillip Melanchthon; the Formula of Concord was given its final form chiefly by Jacob Andreae, Martin Chemnitz, and Nickolaus Selnecker.
