What are the Smalcald Articles and the Treatise on the Power and Primacy of the Pope?

In 1537, Martin Luther was asked to prepare a statement of Lutheran belief for use at a church council, if it was called. Luther’s bold and vigorous confession of faith was later incorporated into the Book of Concord. It was presented to a group of Lutheran rulers meeting in the town of Smalcald. Philip Melanchthon was asked to expand on the subject of the Roman pope and did so in his treatise, which also was included in the Book of Concord.
