In many ways, Pentecostalism revolves around the belief that “victory over sin” is not only possible but expected of “full-gospel” Christians. An interest in eliminating sin and cultivating a holy life echoes the virtues and vices tradition of Thomas Aquinas, Gregory of Nyssa, Evagrius, and other great theologians from Christian history. In the thirteenth century, Aquinas sought to systematically dissect every possible cause, effect, source, and potential method for arresting vice and redirecting it toward virtue. Alternatively, Classical Pentecostal doctrine asserts that the process can be distilled into two or three distinct but easily understood and obtainable supernatural experiences. As Grant Wacker says, “Pentecostals never supposed that divine things were perfectly knowable. But they did suppose that all of the truly important points that human beings needed to know for their salvation could be stated in the same declarative, straightforward language one might use to order bolts at the dry goods store.” That should not be taken to mean that early Pentecostals did not give theology much thought.
