Who wrote the Book of Concord?
The ancient creeds in the Book of Concord were prepared by early church pastors and theologians. Philip Melanchthon, a layman, was a professor of Greek and theology at the University of Wittenberg. He was chiefly responsible for writing the Augsburg Confession, the Apology of the Augsburg Confession, and the Treatise on the Power and Primacy of the Pope. Martin Luther wrote the Small and Large Catechisms and the Smalcald Articles. A group of Lutheran theologians prepared the Formula of Concord. They were Jacob Andreae, Martin Chemnitz, Nicholas Selnecker, David Chytraeus, Andrew Musculus, and Christopher Koerner.
