Georg Calixt

Georg Calixtus, Kallisøn/Kallisön, or Callisen (14 December 1586 – 19 March 1656) was a German Lutheran theologian who looked to reconcile all Christendom by removing all unimportant differences.

Calixtus was born in Medelby, Schleswig. After studying philology, philosophy and theology at Helmstedt, Jena, Giessen, Tübingen and Heidelberg, he travelled through Holland, France and England, where he became acquainted with the leading reformers. On his return in 1614, he was appointed professor of theology at Helmstedt by the duke of Brunswick, who had admired the ability he displayed when a young man in a dispute with the Jesuit Augustine Turrianus.

Learning different Protestant and Roman Catholic teachings, he tried to create a "unifying theology". In 1613 he published a book, Disputationes de Praecipuis Religionis Christianae Capitibus, which provoked the hostile criticism of orthodox Lutheran scholars; in 1619 he published his Epitome theologiae, and some years later his Theologia Moralis (1634) and De Arte Nova Nihusii. Roman Catholics felt them to be aimed at their own system, but they gave so great offence to Lutherans as to induce Statius Buscher to charge the author with a secret leaning to Catholicism.

Scarcely had he refuted the accusation of Buscher, when, on account of his intimacy with the Reformed divines at the conference of Thorn (1645), and his desire to effect a reconciliation between them and the Lutherans, a new charge was leveled against him, principally by Abraham Calovius (1612-1686), of a secret attachment to Calvinism.
