Pietism emphasized the importance of personal piety, inner devotion, and a direct relationship with God, rather than relying solely on external rituals or theological doctrines.

Pietism emerged in the Lutheran churches of Germany in the late 17th century, particularly in the regions of Halle and Wurttemberg.

Philipp Spener, a Lutheran pastor and theologian, is widely regarded as the founder of Pietism. His book "Pia Desideria" (Pious Desires) outlined the principles and practices of the movement.

Pietists emphasized the importance of personal Bible study, prayer, and a deep emotional connection with God. They believed that true Christianity was a matter of the heart, not just outward conformity to religious practices.

Pietism played a significant role in the formation of new Protestant denominations, such as the Moravian Church, the Methodist Church, and the Evangelical Church.

Pietists established schools and orphanages to provide education and care for the poor and marginalized. They also emphasized the importance of practical Christianity, which included caring for the sick, the elderly, and the needy.

Pietism played a significant role in the development of missions and evangelism. Pietists established missionary societies, translated the Bible into different languages, and encouraged lay people to participate in spreading the Christian message.

Pietism emphasized personal piety and emotional experience rather than strict adherence to religious dogma and moral codes. Pietists believed that true Christianity was a matter of the heart, not just outward conformity to religious practices.

While Pietism was a reaction against the rationalism and secularism of the Enlightenment, it also shared some common values and goals, such as the emphasis on education, social reform, and the importance of individual conscience.

Pietism had a significant impact on the development of modern Christianity. It contributed to the rise of evangelicalism and fundamentalism, led to the decline of traditional church authority and the rise of individualism, and promoted ecumenical dialogue and cooperation among different Christian traditions.
