Religious law

Religious law refers to ethical and moral codes taught by religious traditions. Examples include Christian canon law, Islamic sharia, Jewish halakha, and Hindu law.

The two most prominent systems, canon law and sharia, differ from other religious laws in that canon law is the codification of Catholic, Anglican and Orthodox law as in civil law, while sharia derives many of its laws from juristic precedent and reasoning by analogy (as in a common law tradition).

Established religions and religious institutions

A state religion (or established church) is a religious body officially endorsed by the state. A theocracy is a form of government in which a God or a deity is recognized as the supreme civil ruler.

In both theocracies and some religious jurisdictions, conscientious objectors may cause religious offense. The contrary legal systems are secular states or multicultural societies in which the government does not formally adopt a particular religion, but may either repress all religious activity or enforce tolerance of religious diversity.
