(Schröder; c. 1560, Schönfließ, Brandenburg – 1626, Großen-Englis, Hesse), Reformed theologian. Pastor in Rietberg since 1585, he was expelled by Paderborn Jesuits in 1607 and later became pastor in Ropperhausen (Hesse). His 1606 Brennende Fackel attacking the Jesuits has not survived. His Kurzer, doch gründlicher Bericht, published in 1612, describes his shift from Lutheranism to Calvinism, although he is at pains to point out what they have in common.
