Pietism is a movement within Protestant Christianity that emerged in the late 17th century, primarily in Germany. It emphasizes personal faith, heartfelt devotion, and a commitment to living a moral life. Pietists sought to reform the church by focusing on individual piety and the importance of a personal relationship with God. The movement encouraged Bible study, prayer, and community involvement, often leading to the formation of small groups for spiritual growth. Pietism played a significant role in shaping various denominations, including the Moravian Church and Methodism, and it continues to influence contemporary Christian practices.
