Philipp Ronrad Marheineke, a German theologian, born in Ilildesheim, May 1, 1780, died in Berlin, May 31, 1846. He was educated at Gottingen, and in 1806 became professor extraordinary of theology at Erlangen; in 1809 ordinary professor at Heidelberg; and in 1811 ordinary professor at Berlin, and pastor of the church of the Trinity. The first edition of his Grundlehren der christhchen Dogmatik, which was founded on the philosophy of Schelling, appeared in 1819. The second revised edition (Berlin, 1827) was adapted to the Hegelian philosophy. His most important historical work is the Geschichte der deutschen Reformation (4 vols., Berlin, 1816-'34), which reproduces many documentary records. In his Ghristliche Symbolik (3 vols., Heidelberg, 1810-'14), and his Institution es Symbolical (3d ed., 1830), he took a historical and comparative rather than dogmatic view of the principal Christian creeds. The practical results of his aim to demonstrate the unity and harmony of the Scriptures, the church, and the reason appear in his Entwurf der praktischen Theologie (Berlin, 1837). He published several volumes of minor writings and sermons, was one of the editors' of the works of Hegel, and was prominent in the controversies excited by the Symbolic of Mohler, and the mystical tendencies of Gorres, both of whom he opposed.
