This document discusses Pietism, a 17th century Protestant Christian movement that emphasized living a life of personal devotion to God over formal religious observances. It arose in response to the dry formalism of Lutheran orthodoxy. Key figures like Philip Spener and August Francke promoted small group Bible study, social ministry, and a focus on conversion and sanctification. Pietism influenced later leaders like John Wesley and the Methodist movement. The Moravians under Nicholas von Zinzendorf also emphasized heartfelt faith and fellowship. Both Pietism and the Moravians promoted a hands-on, experiential form of Christianity.
