HENKE, ERNST LUDWIG THEODOR: Professor of theology at Marburg; b. at Helmstedt Feb. 22, 1804; d. at Marburg Dec. 1,1872. He was the youngest son of Heinrich Philipp Konrad Henke (q.v.), studied in Helmstedt, at the Collegium Carolinum in Brunswick, at Göttingen (1822-24), and at Jena. In 1826 he became privat-docent in Jena, lecturing on church history and the New Testament. In 1828 he was appointed professor at the Collegium Carolinum in Brunswick, where he lectured on theological encyclopedia, church history, isagogics, logic, and history of philosophy. In 1833 , he became professor of exegesis and church history at Jena. In 1836 he removed to Wolfenbüttel as councilor of the consistory and director of the theological seminary; as a partial fulfilment of his duties here he lectured on Biblical theology and the epistles of Paul, and directed the practical exercises of the candidates for the ministerial office. In 1839 he followed a call to Marburg; he lectured on homiletics, liturgics, church history, history of dogma, Biblical theology, and propsedeutics, assumed the leadership of the Homiletical Society, and in 1843 was entrusted with the superintendency of the Seminarium Thilippinum; in 1848 he became also first librarian of the university library.

Henke's theology was the result of his comprehensive studies in church history and philosophy. He considered the dualism of faith and science an essential factor of the human mind; a higher unity

may be postulated, but it can not be realized. His broad theological views made it impossible for him to look with favor upon confessional particularism and Pietistic narrowness. He advocated the right of the Evangelical Union in the fullest and broadest sense. In religion, he maintained, love and gratitude toward Christ must find expression in different formulas according to the different states of religious knowledge. Owing to his consistent separation of religion and theology, he considered it the right and duty of science to test and change the transmitted systems of 1eligion.

Henke's literary productions were numerou9. The most important in the sphere of church history was Georg Calixtus Land seine Zeit (2 vols., Halle, 1853-1860). He issued several addresses and memorials of deceased teachers and colleagues. The Evangelical Union was treated by him in Das Verhaltnis Luthers and Melanchthons zu einander (Marburg, 1860). He also wrote Das Unionakolloquium zu Kassel im JvA 1661 (1861); Spener's pia desideria and Are ErfWung (1862); Sehleiermacher und die Union (1869). With his pupil Lindenthal he issued the first edition of Abelard's Sic et Non (1851), and he was a diligent contributor to the Hallische Encykiopadie, Konversationslexicon der Gegentuart and the first edition of the Herzog Realencyklopddie.
