A Diploma in Canon Law for every Lawyer willing to study more into the ecclesiastical courts procedures. Canon law refers to the body of ecclesiastical law that developed within Christianity, particularly Roman Catholicism, governing the internal hierarchy and administration of the church. Canon law includes both divine law and ecclesiastical law. Divine law is unchangeable and is applicable to every human being for example, the law against murder. Ecclesiastical law is rooted in Church law and is not infallible, although it is authoritative for example, the laws regarding fast and abstinence.
