Answer:
Religions organize themselves—their institutions, practitioners, and structures—in a variety of fashions. For instance, when the Roman Catholic Church emerged, it borrowed many of its organizational principles from the ancient Roman military and turned senators into cardinals, for example. Sociologists use different terms, like ecclesia, denomination, and sect, to define these types of organizations. Scholars are also aware that these definitions are not static. Most religions transition through different organizational phases. For example, Christianity began as a cult, transformed into a sect, and today exists as an ecclesia.
Cults, like sects, are new religious groups. In the United States today this term often carries pejorative connotations. However, almost all religions began as cults and gradually progressed to levels of greater size and organization. The term cult is sometimes used interchangeably with the term new religious movement (NRM). In its pejorative use, these groups are often disparaged as being secretive, highly controlling of members’ lives, and dominated by a single, charismatic leader.
Controversy exists over whether some groups are cults, perhaps due in part to media sensationalism over groups like polygamous Mormons or the Peoples Temple followers who died at Jonestown, Guyana. Some groups that are controversially labeled as cults today include the Church of Scientology and the Hare Krishna movement.
