Although their faith was chiefly the product of a forced union by the government in Prussia, the Evangelicals by conviction wished to minimize the centuries-old points of contention between Lutheran and Reformed doctrine and practice. This attitude of moderation was enabled in large measure by the rise of pietism, which stressed a more emotional, less rationalistic approach to the teachings of the Bible, thus disinclining scholars and pastors toward technicalities or polemics. Many Evangelical parishes were founded by pastors trained in interdenominational missionary societies such as the St. Chrischona Pilgrim Mission in Basel, Switzerland, in the early 19th century; they immigrated to the United States to assist settlers fleeing Prussian militarism.
