Question: What is a term for the institution allowing church courts to have relevant functions in secular society and churches that align with it?

full_context: Document 1: Protestantism: Several countries have established their national churches, linking the ecclesiastical structure with the state. Jurisdictions where a Protestant denomination has been established as a state religion include several Nordic countries; Denmark (including Greenland), the Faroe Islands (its church being independent since 2007), Iceland and Norway have established Evangelical Lutheran churches. Tuvalu has the only established church in Reformed tradition in the world, while Tonga—in the Methodist tradition. The Church of England is the officially established religious institution in England, and also the Mother Church of the worldwide Anglican Communion.
Document 2: Mary, mother of Jesus: The multiple churches that form the Anglican Communion and the Continuing Anglican movement have different views on Marian doctrines and venerative practices given that there is no single church with universal authority within the Communion and that the mother church (the Church of England) understands itself to be both "catholic" and "Reformed". Thus unlike the Protestant churches at large, the Anglican Communion (which includes the Episcopal Church in the United States) includes segments which still retain some veneration of Mary.
Document 3: List of Catholic dioceses in the United States: The Roman Catholic Church has a total of 197 particular churches -- consisting of 32 territorial archdioceses, 145 territorial dioceses, the Archdiocese for the Military Services, USA (serving members of the US Armed Forces and Diplomatic Corps, and those in facilities of the Veterans Administration and their dependents), and the Personal Ordinariate of the Chair of Saint Peter (serving Catholics who were formerly Anglicans) within the Roman Rite; and two archieparchies and 16 eparchies in the Eastern Catholic Churches -- in the 50 United States and the US Virgin Islands. The pastor of any particular church other than an ordinariate must be episcopally ordained, but his title conforms to that of his jurisdiction: the pastor of an archdiocese is an archbishop, the pastor of a diocese is a bishop, the pastor of an archieparchy is an archieparch, the pastor of an eparchy is an eparch, and the pastor of an exarchate is an exarch. The pastor of an ordinariate, titled the ``ordinary ''(which is a term also used generically for the pastor of any particular church), may be either a bishop if celibate, or a presbyter (priest) if married, but he holds the same power of governance of his ordinariate that a bishop has of his diocese in either case; Pope Benedict XVI deliberately instituted this provision to permit married, former Anglican bishops who come into full communion with the Catholic Church along with many of their congregants to accede to office while respecting sensitivities in ecumenical relations with the Eastern Orthodox Churches, which also maintain a celibate episcopacy. The pastor of each particular church is, ex officio, a full member of the United States Conference of Catholic Bishops (USCCB). Auxiliary and retired bishops are also members of the Conference but have no vote.
Document 4: Anglican Network in Canada: The Anglican Network in Canada (ANiC) is a group of Anglican churches in Canada and the United States established in 2005 under the jurisdiction of the Anglican Province of the Southern Cone, a province of the Anglican Communion. It was a founding diocese of the Anglican Church in North America in June 2009. It comprises 73 parishes in nine Canadian provinces, Alberta, British Columbia, Saskatchewan, Manitoba, New Brunswick, Newfoundland, Nova Scotia, Ontario, and Québec, and two American states, Massachusetts and Vermont. The Canadian provinces with more parishes are British Columbia and Ontario, both with 26. Their first Moderator Bishop was Don Harvey, from 2009 to 2014, when he was succeeded by Charlie Masters.
Document 5: Equity (law): For much of its history, the English common law was principally developed and administered in the central royal courts: the Court of King's Bench, the Court of Common Pleas, and the Exchequer. Equity was the name given to the law which was administered in the Court of Chancery. The Judicature Reforms in the 1870s effected a procedural fusion of the two bodies of law, ending their institutional separation. The reforms did not effect any substantive fusion, however. Judicial or academic reasoning which assumes the contrary has been described as a ``fusion fallacy ''.
Document 6: Canon law: Roman canon law had been criticized by the Presbyterians as early as 1572 in the Admonition to Parliament. The protest centered on the standard defense that canon law could be retained so long as it did not contradict the civil law. According to Polly Ha, the Reformed Church Government refuted this claiming that the bishops had been enforcing canon law for 1500 years.
Document 7: Canon law: The institutions and practices of canon law paralleled the legal development of much of Europe, and consequently both modern civil law and common law (legal system) bear the influences of canon law. Edson Luiz Sampel, a Brazilian expert in canon law, says that canon law is contained in the genesis of various institutes of civil law, such as the law in continental Europe and Latin American countries. Sampel explains that canon law has significant influence in contemporary society.
Document 8: Canon law: The law of the Eastern Catholic Churches in full union with Rome was in much the same state as that of the Latin or Western Church before 1917; much more diversity in legislation existed in the various Eastern Catholic Churches. Each had its own special law, in which custom still played an important part. In 1929 Pius XI informed the Eastern Churches of his intention to work out a Code for the whole of the Eastern Church. The publication of these Codes for the Eastern Churches regarding the law of persons was made between 1949 through 1958 but finalized nearly 30 years later.
Document 9: English Reformation: Based on Henry VIII's desire for an annulment of his marriage (first requested of Pope Clement VII in 1527), the English Reformation was at the outset more of a political affair than a theological dispute. The reality of political differences between Rome and England allowed growing theological disputes to come to the fore. Until the break with Rome, it was the Pope and general councils of the Church that decided doctrine. Church law was governed by canon law with final jurisdiction in Rome. Church taxes were paid straight to Rome, and the Pope had the final word in the appointment of bishops.
Document 10: Canon law: The Catholic Church has what is claimed to be the oldest continuously functioning internal legal system in Western Europe, much later than Roman law but predating the evolution of modern European civil law traditions. What began with rules ("canons") adopted by the Apostles at the Council of Jerusalem in the first century has developed into a highly complex legal system encapsulating not just norms of the New Testament, but some elements of the Hebrew (Old Testament), Roman, Visigothic, Saxon, and Celtic legal traditions.
Document 11: Canon law: In the Church of England, the ecclesiastical courts that formerly decided many matters such as disputes relating to marriage, divorce, wills, and defamation, still have jurisdiction of certain church-related matters (e.g. discipline of clergy, alteration of church property, and issues related to churchyards). Their separate status dates back to the 12th century when the Normans split them off from the mixed secular/religious county and local courts used by the Saxons. In contrast to the other courts of England the law used in ecclesiastical matters is at least partially a civil law system, not common law, although heavily governed by parliamentary statutes. Since the Reformation, ecclesiastical courts in England have been royal courts. The teaching of canon law at the Universities of Oxford and Cambridge was abrogated by Henry VIII; thereafter practitioners in the ecclesiastical courts were trained in civil law, receiving a Doctor of Civil Law (D.C.L.) degree from Oxford, or a Doctor of Laws (LL.D.) degree from Cambridge. Such lawyers (called "doctors" and "civilians") were centered at "Doctors Commons", a few streets south of St Paul's Cathedral in London, where they monopolized probate, matrimonial, and admiralty cases until their jurisdiction was removed to the common law courts in the mid-19th century.
Document 12: English law: Since 1189, English law has been described as a common law rather than a civil law system; in other words, no comprehensive codification of the law has taken place and judicial precedents are binding as opposed to persuasive. This may be a legacy of the Norman conquest of England, when a number of legal concepts and institutions from Norman law were introduced to England. In the early centuries of English common law, the justices and judges were responsible for adapting the system of writs to meet everyday needs, applying a mixture of precedent and common sense to build up a body of internally consistent law. An example is the Law Merchant derived from the ``Pie - Powder ''Courts, named from a corruption of the French pieds - poudrés (`` dusty feet'') implying ad hoc marketplace courts. As the Parliament of England became ever more established and influential, legislation gradually overtook judicial law - making such that today, judges are only able to innovate in certain very narrowly defined areas.
Document 13: Canon law: Other churches in the Anglican Communion around the world (e.g., the Episcopal Church in the United States, and the Anglican Church of Canada) still function under their own private systems of canon law.
Document 14: Protestantism: Anglicanism comprises the Church of England and churches which are historically tied to it or hold similar beliefs, worship practices and church structures. The word Anglican originates in ecclesia anglicana, a medieval Latin phrase dating to at least 1246 that means the English Church. There is no single "Anglican Church" with universal juridical authority, since each national or regional church has full autonomy. As the name suggests, the communion is an association of churches in full communion with the Archbishop of Canterbury. The great majority of Anglicans are members of churches which are part of the international Anglican Communion, which has 80 million adherents.
Document 15: Canon law: In the Catholic Church, canon law is the system of laws and legal principles made and enforced by the Church's hierarchical authorities to regulate its external organization and government and to order and direct the activities of Catholics toward the mission of the Church.
