§ 159.2. =The Syncretist Controversy.=--Since the Hofmann controversy (§ 141, 15) the University of Helmstadt had shown a decided humanistic tendency, and gave even greater freedom in the treatment of doctrines than the Formula of Concord, which it declined to adopt. To this school belonged =George Calixt=, and from A.D. 1614 for forty years he laboured in promoting its interests. He was a man of wide culture and experience, who had obtained a thorough knowledge of church history, and acquaintance with the most distinguished theologians of all churches, during his extensive foreign travels, and therewith a geniality and breadth of view not by any means common in those days. He did not indeed desire any formal union between the different churches, but rather a mutual recognition, love, and tolerance. For this purpose he set, as a secondary principle of Christian theology, besides Scripture, as the primary principle, the consensus of the first five centuries as the common basis of all churches, and sought to represent later ecclesiastical differences as unessential or of less consequence. This was denounced by strict Lutherans as Syncretism and Cryptocatholicism. In A.D. 1639 the Hanoverian preacher Buscher charged him with being a secret Papist. After the Thorn Conference of A.D. 1645, a violent controversy arose, which divided Lutherans into two camps. On the one side were the universities of Helmstadt and Königsberg; on the other hand, the theologians of the electorate of Saxony, Hülsemann of Leipzig, Waller of Dresden, and Abr. Calov, who died professor in Wittenberg in A.D. 1686. Calov wrote twenty-six controversial treatises on this subject. Jena vainly sought to mediate between the parties. In the _Theologorum Sax. Consensus repetitus Fidei vera Lutheranæ_ of A.D. 1655, for which the Wittenberg divines failed to secure symbolical authority, the following sentiments were branded as Syncretist errors: That in the Apostles’ Creed everything is taught that is necessary to salvation; that the Catholic and Reformed systems retain hold of fundamental truths; that original sin is of a merely privative nature; that God _indirecte, improprie, et per accidens_ is the cause of sin; that the doctrine of the Trinity was first clearly revealed in the New Testament, etc. Calixt died A.D. 1656 in the midst of most violent controversies. His son Ulrich continued these, but had neither the ability nor moderation of his father. Even the peaceably disposed Conference of Cassel of A.D. 1661 (§ 154, 4) only poured oil on the flames. The strife lost itself at last in actions for damages between the younger Calixt and his bitter opponent Strauch of Wittenberg. Wearied of these fruitless discussions, theologians now turned their attention to the rising movement of Pietism.[467]
