The Brethren / Jim Roberts Group

The Brethren, often called simply the Jim Roberts Group after its founder, is an itinerant Christian movement that began recruiting on American college campuses in the 1970s. Roberts, known within the group as "Brother Evangelist," led followers into a fully mobile communal life, with members travelling on foot or by bicycle between cities rather than settling in a fixed compound, a pattern that has made the group unusually difficult for outsiders, researchers, and even families to track.

On joining, members typically surrendered all personal possessions and money, adopted new names in place of their birth identities, and wore plain, deliberately old-fashioned clothing designed to mark them as separate from mainstream society. Contact with family of origin was severed almost completely, and the group's itinerant lifestyle, moving frequently and without fixed addresses or phones, made it extremely difficult for parents to locate or communicate with adult children who had joined, a pattern that families and journalists have often described using the language of disappearance rather than voluntary departure.

Because the group has no fixed property, formal business structure, or public leadership beyond Roberts himself, it has generated comparatively few court cases relative to other entries in this catalogue; its documentation instead rests heavily on parental advocacy, journalistic investigation into missing young adults later found to be living with the group, and assessments by exit-counselling specialists such as Steven Hassan, whose organisation has used the group as a case study in its behaviour-information-thought-emotion control framework. Roberts died in 2015, and the remaining membership, believed to be small, has continued the group's itinerant practices without him.

The Brethren illustrates a distinct control profile within this catalogue: rather than relying on a fixed compound, a business empire, or visible criminal prosecutions, it achieves comparably deep separation from family and prior identity through mobility itself, using constant movement and the loss of a fixed address as a substitute for walls and gates. Parents who have spent years searching for adult children who joined describe an experience closer to a missing-persons case than a typical account of a relative leaving for a new faith. Documentation of the group remains comparatively thin, reflecting its low public visibility and the scarcity of court or documentary records relative to more institutionally documented entries in this catalogue.
