Emotion is an important part of religions in America. There is great diversity among emotional styles. Some groups are highly emotional, others relatively low in emotional expression, and some occupy a middle ground. Religious life is characterized by cultivation and expression of many emotions. Four that are of particular importance for Americans are wonder, empathy, anticipation, and the feeling of emptiness. Some emotions are treated as commodities. The study of emotion in religion enables fresh perspectives on the interwovenness of emotion, religion, and culture. The investigation of the emotional lives of religious persons in America can be advanced through study of persons’ reporting of their experiences alongside research bearing on cultural expectations for emotional life.
