Does the act of attending religious services "cause" individuals to participate in politics? There is no known literature that examines this question using longitudinal, individual-level data. Therefore, using the Youth Parent Socialization Panel Study, this analysis examines three theoretical possibilities: the indirect, direct, and null relationships. The results show that changes in religious attendance are primarily indirectly linked to political participation through civic activity, a factor highly correlated with political participation. There is also some limited evidence for a direct effect. As individuals increase their political participation over time, they are slightly more likely to participate in political activities and vote. But, the findings also imply that the previous literature has likely overstated the role of religious attendance in generating political participation. Once individuals start participating politically, they continue to do so regardless of changes in their attendance at places of worship.
