Claims that religion can influence ethical behavior in business are plausible to many people but problematic in light of existing research. Our analysis indicates that religious role expectations, internalized as a religious self-identity, can influence ethical behavior. However, relationships of religious role expectations to behavior are moderated by religious identity salience and religious motivational orientation. We conclude by discussing the influence of organizational context on religious identity salience and the need for innovative and interdisciplinary empirical research on religion and ethical behavior in organizations.
