He attended the diets of Regensburg (1557) and Augsburg (1559), became professor of theology in the University of Tübingen (1562), and provost of the church of St. George. He was active in Protestant discussions and movements, particularly in the adoption of a common declaration of faith by the two parties.
He was a signatory of the 1577 Formula of Concord, and editor with Martin Chemnitz of the 1580 Book of Concord. In the latter part of his life he traveled in Bohemia and Germany, working for the consolidation of the Reformation, conferring with pastors, magistrates, and princes. He was the author of more than 150 works, nearly all polemical and vigorously written, for the most part directed against Calvinism.
