State religion
A state religion (also called an established religion or official religion) is a religious body or creed officially endorsed by the state. A state with an official religion, while not secular, is not necessarily a theocracy, a country whose rulers have both secular and spiritual authority. State religions are official or government-sanctioned establishments of a religion, but the state does not need to be under the control of the religion (as in a theocracy) nor is the state-sanctioned religion necessarily under the control of the state.
