Ecclesiastical Law:

Generally Ecclesiastical Law is the authoritative rules that govern the Christian Church, and covers internal policy and relations in secular power.
Note: The word secular means not connected with religious or spiritual matters, meaning that the secular power is referring to either the state or monarchy.
Although the history of the Christian Church is complexed, to better understand the legal system today, and to simplify the situation we should make the distinction between the “Free Christian Church” or “Protestant Church” and the “Church of Rome” or the “Roman Catholic Church”.
This distinction is due to the claim of the “Roman Catholic Church” to be the only Church, with their laws being of universal obligation.
With the creation of the Christian name, and adoption of the surname, legal fictions are created within ecclesiastical law, as all certificates of birth are controlled by the Vatican.
All deeds are controlled by the Vatican, through ecclesiastical law, and are in fact deeds of trust and not deeds of property.
For example: If you wished to change your name you would use the Ecclesiastical Deed Pole, however you are not changing your name, but the name of your legal fiction or corporation, which is controlled by the Vatican.
