Stark and Finke (2000) jettison the functionalism of Durkheim and focus exclusively on religious rituals, rather than all repeated social interactions, arguing that confidence in religious explanations increases with ritual participation. Rituals generally follow customs or traditions, but they are deliberate ceremonies in which the object is exchanged with a god or gods and the outcome is reinforcement of the “central ideas and ideals of the group.” Rituals are thus intentional features of religious life and can shift with alterations in either the demand or the supply of religious goods.
