A sect is typically defined as a group that has broken away from a larger religious institution. This definition reflects the characteristics of a sect, which often emerges in response to perceived deficiencies or disagreements within the parent religion. Sects may adopt distinct beliefs, practices, or organizational structures that differentiate them from the mainstream tradition from which they departed. They often seek to return to what they consider the true teachings or practices of their faith, which can involve a re-interpretation of scripture or established doctrine.

In contrast, a well-established religious organization generally refers to a denomination or mainstream faith that usually has established rituals, beliefs, and a large following, which does not accurately capture the essence of what constitutes a sect. A mainstream national religion typically denotes a religion recognized as the primary faith within a nation and often lacks the connotations of schism or break with another entity, whereas a cult is usually associated with extreme or unconventional practices that may not fit the traditional definitions of sect or religion. Hence, the definition of a sect as a group that has separated from a larger religious institution highlights the critical aspects of breaks in unity and the pursuit of a modified belief system.
