Neo-Lutheranism
Neo-Lutheranism was a 19th-century Christian revival movement within Lutheranism which began with the Pietist-driven Erweckung, or Awakening, and developed in reaction against theological rationalism and Pietism. The neo-Lutheran movement followed the Old Lutheran tradition in the Kingdom of Prussia, and focused on a reassertion of the identity of Lutherans as a distinct group within the broader community of Protestant Christians, with a renewed focus on the Lutheran Confessions as a key source of Lutheran doctrine in the modern era.
