Canon law is the body of laws and regulations made or adopted by ecclesiastical authority (Church leadership), for the government of the Christian organization and its members. It is the internal ecclesiastical law governing the Catholic Church (both Latin Rite and Eastern Catholic Churches), the Eastern and Oriental Orthodox churches, and the Anglican Communion of churches. The way that such church law is legislated, interpreted and at times adjudicated varies widely among these three bodies of churches. In all three traditions, a canon was originally a rule adopted by a council; these canons formed the foundation of canon law.
