Revivals were hardly new in the nineteenth century… Earlier revivals generally had happened within the contexts of churches with established liturgical traditions. A revival might interrupt a liturgical pattern but generally did not displace it. In the nineteenth century, however, the pattern of revival worship became the basis of regular weekly worship in thousands of evangelical congregations across North America. To this day, thousands of North American Christians worship each week in what might be called a revivalist liturgical pattern.
