An 
ecclesia is one of the four members of the most common sociological typology of 
religious groups -- the other three are the 
denomination, the 
sect and the 
cult. An ecclesia is a religious group which is strongly integrated with the dominant social and political culture. Often ecclesias are 
state churches, though they need not be: a state church by definition has official legal recognition of its role in the society, while an ecclesia might not.
