Canon Law:

The term Canon Law comes from the Latin phrase, Ius Canonicum meaning “a System of Laws”, controlled and enforced by hierarchical authorities.

The word Canon is also said to come from the Ancient Greek word Kanon, meaning a “straight measuring rod, or ruler”.

Over time people within the Catholic Church used Canon Law to regulate, govern and control people towards the mission of the church.

Ecclesiastical law, which is supposed to be indirectly based upon immutable divine law and natural law, or the word of god, is now intertwined with Canon Law which controls the Roman Catholic Church, The Eastern Orthodox Church and the Anglian Communion Church.
