In this commentary, I concur with Cromby that more attention should be given to beliefs in terms of definition, measurement, and investigation, particularly of their development and their relations with aspects of health and well-being. Within the context of religious beliefs, I argue, however, that beliefs should not be considered affect or emotion but rather should be examined in relation to them, and that their development likely arises through myriad sources. I provide an alternative definition of religious beliefs and conclude with suggestions for future research on religious beliefs and health.
