This study examined the endorsement of three different sources of a calling—external summons, destiny, and perfect fit—and how the endorsement of these sources related to levels of living a calling, job satisfaction, and life satisfaction. With a sample of 200 employed adults, participants were asked to select a source group that best described where their calling originated. A multivariate analysis of variance revealed no significant differences among the three primary source groups on levels of living a calling, job satisfaction, or life satisfaction. However, group membership was a significant moderator in the relation of living a calling to life satisfaction. Specifically, the relation of living a calling to life satisfaction was more pronounced for participants endorsing a destiny belief than for those endorsing other sources. Overall, results indicate that as long as workers feel they are living out their calling, the source of their calling matters little in terms of how calling links to job and life satisfaction.
