Question: What state of Germany was Ernst Wilhelm Hengstenberg from?
Context: Neo-Lutheranism was a 19th-century revival movement within Lutheranism which began with the Pietist driven "Erweckung," or "Awakening", and developed in reaction against theological rationalism and pietism.  This movement followed the Old Lutheran movement and focused on a reassertion of the identity of Lutherans as a distinct group within the broader community of Christians, with a renewed focus on the Lutheran Confessions as a key source of Lutheran doctrine.  Associated with these changes was a renewed focus on traditional doctrine and liturgy, which paralleled the growth of Anglo-Catholicism in England.  It was sometimes even called "German Puseyism".  In the Roman Catholic Church in Germany, neo-Lutheranism was paralleled by Johann Adam Möhler.  The chief literary organ of the neo-Lutheranism was "Evangelische Kirchenzeitung", edited by Ernst Wilhelm Hengstenberg.
