Pratorius, Abdias a German theologian of some renown, was born in 1524 in the Brandenburg territory. He was master of many languages, and especially noted as a Greek scholar. He was at first rector of a school at Magdeburg, lived then at Frankfort-on-the-Oder, was called in 1560 to the electoral court of Brandenburg, and died in 1573 as professor of philosophy at Wittenberg. He attacked the Lutheran distinction between law and Gospel, and the definition of the latter as an unconditional message of grace. The most distinguished of his adversaries was Andrew Musculus, one of the authors of The Formula of Concord.
