This research explores the macro-level influences of religion on the marketplace by showing how religion influences beliefs of dominion and stewardship, which subsequently influence marketplace attitudes and sustainable behavior. A survey of 1,101 adults was conducted, with results showing religious individuals express greater beliefs of dominion while non-religious individuals express greater beliefs of stewardship. Stewardship beliefs in turn positively influence one’s tendency to engage in sustainable behavior, while dominion does not. These beliefs also mediate the relationship between religiosity and behavior, though the effects of dominion are negative and weaker than those of stewardship. We also provide insight into whom consumers hold responsible for solving sustainability issues, with the non-religious placing responsibility on consumers and the religious placing responsibility on producers. We build off value-belief-norm and attribution theories to discuss how our findings contribute to sustainability in marketing systems and provide greater understanding of the intersection between religion and sustainability.
