The penitentiary in the United States of America originated as a religious institution. Its roots lie in the belief that inmates could reform if they were given an opportunity to engage in reflection, prayer, Bible-reading and work, thus establishing a new personal foundation for functioning as productive members of the larger society. Not surprisingly, given American's predilection for maintaining a secular civil society, this original foundation for the prison eventually fell from favour, and American penological theories became more sociological or psychological in nature. The fact remains, however, that society in the United States is broadly religious, and prisons continue to address the religious beliefs of inmates and how to accommodate those beliefs in a penological setting. This comment provides a case study on this topic, based on littigation concerning the provision of kosher food to Orthodox inmates in the prisons in Colorado.
