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 are new religious movements and are often characterized as small, secretive, and highly controlling of members and may have a charismatic leader. 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). The new term may be an attempt to lessen the negativity that the term ‘cult’ has amassed.
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.
A sect is an offshoot of a larger religious group that has distinct beliefs and practices that deviate from that group. Most of the well-known Christian denominations in the United States today began as sects. For example, the Methodists and Baptists protested against their parent Anglican Church in England, just as Henry VIII protested against the Catholic Church by forming the Anglican Church. From “protest” comes the term Protestant.
Occasionally, a sect is a breakaway group that may be in tension with larger society. They sometimes claim to be returning to “the fundamentals” or to contest the veracity of a particular doctrine. When membership in a sect increases over time, it may grow into a denomination. Often a sect begins as an offshoot of a denomination, when a group of members believes they should separate from the larger group.
Some sects do not grow into denominations. Sociologists call these established sects. Established sects, such as the Amish or Jehovah’s Witnesses fall halfway between sect and denomination on the ecclesia–cult continuum because they have a mixture of sect-like and denomination-like characteristics.
A denomination is a large, mainstream religious organization, but it does not claim to be official or state sponsored. It is one religion among many. For example, Baptist, African Methodist Episcopal, Catholic, and Seventh-day Adventist are all Christian denominations.
The term ecclesia, originally referring to a political assembly of citizens in ancient Athens, Greece, now refers to a congregation. In sociology, the term is used to refer to a religious group that most all members of a society belong to. It is considered a nationally recognized, or official, religion that holds a religious monopoly and is closely allied with state and secular powers. The United States does not have an ecclesia by this standard; in fact, this is the type of religious organization that many of the first colonists came to America to escape.
There are many countries in Europe, Asia, Central and South America, and Africa that are considered to have an official state-church. Most of their citizens share similar beliefs, and the state-church has significant involvement in national institutions, which includes restricting the behavior of those with different belief systems. The state-church of England is the Church of England or the Anglican Church established in the 16th century by King Henry VIII. In Saudi Arabia, Islamic law is enforced, and public display of any other religion is illegal. Using this definition then, it can be said that the major Abrahamic systems of Christianity, Judaism, and Islam, are ecclesia; in some regions, they are considered a state-church.
One way to remember these religious organizational terms is to think of cults, sects, denominations, and ecclesia representing a continuum, with increasing influence on society, where cults are least influential and ecclesia are most influential.
