Although prior research has had a tendency to confirm a negative association between religiousness and crime, criminologists have been slow to incorporate new concepts and emergent issues from the scientific study of religion into their own research. The self‐identity phrase “spiritual but not religious” is one of them, which has been increasingly used by individuals who claim to be “spiritual” but disassociate themselves from organized religion. This study first examines differences in crime between “spiritual‐but‐not‐religious” individuals and their “religious‐and‐spiritual,” “religious‐but‐not‐spiritual,” and “neither‐religious‐nor‐spiritual” peers in emerging adulthood. Specifically, we hypothesize that the spiritual‐but‐not‐religious young adults are more prone to crime than their “religious” counterparts, while expecting them to be different from the “neither” group without specifying whether they are more or less crime prone. Second, the expected group differences in crime are hypothesized to be explained by the microcriminological theories of self‐control, social bonding, and general strain. Latent‐variable structural equation models were estimated separately for violent and property crimes using the third wave of the National Longitudinal Study of Adolescent Health. The overall results tend to provide a partial support for the hypotheses. Implications for criminology and future research are discussed.
