World religions
Many scholars have used the "World Religions" category alongside other "catch-all" categories such as "new religious movements" and "indigenous religions". The scholar of religion Steven J. Sutcliffe compared the relationship between the three categories to the English football league system, with the "world" religions forming a Premier League, the "new" religions forming a Championship, and "indigenous" religions a First Division. That groups that get placed in categories like "indigenous religions" get treated less seriously than the "world religions" by many scholars was noted by the scholar of religion Graham Harvey. Harway said  that "indigenous religions should receive similarly respectful treatment to that considered appropriate to the larger 'World Religions'."
