About Johann Arndt
Johann Arndt was a German Lutheran theologian and mystic who wrote several influential books of devotional Christianity. Although reflective of the period of Lutheran Orthodoxy, he is seen as a forerunner of Pietism, a movement within Lutheranism that gained strength in the late 17th century.
