A religious organization that claims membership of the entire population of a society or serves as the country's official religion is called what?

• A. Church
• B. Denomination
• C. Cults
• D. Ecclesia

Answer: (D)

Ecclesia refers to a religious organization that claims universal membership of the society or functions as the country’s official religion. This means the group is integrated with the state and seen as encompassing or representing all citizens. A church, by contrast, is a large religious body that individuals join or affiliate with, but not necessarily claiming everyone in society. A denomination is a major division within a religion that coexists with others, rather than claiming universal membership. A cult is typically a newer or minority group outside mainstream society and not tied to the state. So the term that matches a religion claiming all members or serving as the official faith is ecclesia.
