Why it matters for reading Scripture
How churches govern themselves, and why traditions differ on authority and ministry. Every tradition governs itself by law, whether canons, codes, church orders, constitutions or congregational rules.
Practical theologyHow is it lived and shared?
Canon law and church polity is the study of how churches govern themselves and how their law works. Canon law is the body of laws made within a church by lawful church authority, usually written as numbered canons; church order is the wider term for the constitutions, books of order, disciplines and manuals of Protestant churches.

How churches govern themselves, and why traditions differ on authority and ministry. Every tradition governs itself by law, whether canons, codes, church orders, constitutions or congregational rules.
Every tradition governs itself by law: canons, codes, church orders, constitutions or congregational rules; most name a body and texts that speak for them; some have no single binding voice.
They divide on where authority lies (pope, synod, presbytery, conference or congregation), how decisions bind, succession and who may ordain, women's ordination, discipline, and national churches' independence.
Governs by two codes: the 1983 Code of Canon Law, in seven books and 1,752 canons, for the Latin Church, and the 1990 Code of Canons of the Eastern Churches for the Eastern Catholic Churches.
The Pope and the college of bishops hold the teaching office, and bishops succeed the apostles by divine institution. Only a baptized man receives ordination validly, and the Catholic Church does not recognize Anglican or Protestant orders.
Govern by the canons of the ecumenical and local councils, the Apostolic Canons and the canonical letters of the Fathers, gathered in the Pedalion of 1800 and applied by the synod of each self-governing church.
Apostolic Canon 34 says the bishops of every nation must acknowledge the one who is first among them, who does nothing important without the consent of all. Who may grant autocephaly is disputed, and Ukraine is the sharpest current case.
The Coptic Orthodox Church is headed by the Pope of Alexandria, whose authority with the Holy Synod extends inside and outside Egypt; regulations adopted in 2014 make the altar lot among three nominees mandatory in electing the Pope.
The Fetha Nagast, compiled in 1238 by the Coptic jurist Ibn al-Assal, served as the law of church and state in Ethiopia until 1974.
The Church of England keeps its own canons, and its Measures, approved by a General Synod of bishops, clergy and laity, have the force of an Act of Parliament once given Royal Assent.
The member churches of the Anglican Communion are autonomous, and the Lambeth Conference has no legislative function. Gafcon disputes Canterbury-centered leadership and advances a competing claim to Anglican identity.
The Lutheran Reformation replaced canon law with church orders issued by cities and princes, among them those Johannes Bugenhagen wrote for Braunschweig, Hamburg, Lübeck, Pomerania and Denmark.
Modern Lutheran churches govern by constitution: in the Evangelical Lutheran Church in America the Churchwide Assembly is the highest legislative authority and alone may amend the constitution. On succession, Lutheran churches vary.
Place authority in councils of ministers and elders: the session of a congregation, the presbytery, the synod and the General Assembly.
The Presbyterian Church in America's Book of Church Order calls the jurisdiction of church courts "only ministerial and declarative" and opens the offices of elder and deacon to men only, while the Presbyterian Church (U.S.A.) ordains women. The Church of Scotland's Articles Declaratory state that it receives from Christ alone the right, subject to no civil authority, to legislate and adjudicate in doctrine, worship, government and discipline.
Methodist polity is connexional.
In British Methodism supreme authority is vested in the Conference, which stations ministers each year; in the United Methodist Church the General Conference sets doctrine and the Book of Discipline, and since 5 November 2025 it sets a common core while regions adapt parts of the Discipline.
Hold that each local congregation is autonomous and that associations and conventions have no authority over one another or over the churches.
The Baptist Faith and Message calls confessions "only guides in interpretation, having no authority over the conscience". The Southern Baptist Convention limits the office of pastor to men and enforces its confession through the test of friendly cooperation.
Describe themselves as a cooperative fellowship rather than a denomination, with local churches self-governing under district and national councils and a Constitution and Bylaws last revised in 2023.
Their leadership states that no position is closed to a woman in credentialed ministry.
Only the General Conference in session can change the Church Manual, and its president has said that decisions of the session have the highest authority in the church.
In 2015 delegates voted 1,381 to 977 against allowing divisions to provide for women's ordination.
Link congregations through personal relationships around apostolic figures who can mobilize resources and decide quickly.
They took shape in the 1970s and are often registered as charitable trusts.
Often combine a prophet or bishop with a founding family and a written constitution.
In the succession disputes of the Nazareth Baptist (Shembe) Church, South Africa's civil courts have ruled on constitutions, trusts and succession procedures, not on spiritual leadership as such. In 2025 rival factions of the Zion Christian Church in Botswana were told to follow the church's constitutional processes.
The First Council of Nicaea (325) rules that a bishop is chosen by the bishops of the province, at least three meeting, with the metropolitan ratifying, and keeps the ancient customs of Alexandria, Rome and Antioch. The First Council of Constantinople (381) forbids bishops to act outside their own dioceses.4344
The Coptic jurist Ibn al-Assal compiles the Fetha Nagast, the "law of the kings", in Arabic from Greek sources; translated into Ge'ez, its first part governs the church, patriarchs, bishops, priests, deacons and deaconesses.13
Johannes Bugenhagen writes Lutheran church orders for Braunschweig (1528), Hamburg (1529), Lübeck (1531), Pomerania (1534) and Denmark (1537), covering worship, schools and poor relief.21
The Pedalion, compiled on Mount Athos by Nikodemos the Hagiorite and Agapios, is printed in Leipzig with the permission of the Holy Synod of the Ecumenical Patriarchate.7
Leo XIII's Apostolicae curae declares Anglican ordinations "absolutely null and utterly void", for defects of form and intention.6
Under the Church of England Assembly (Powers) Act, Measures go to Parliament's Ecclesiastical Committee and, once approved by both Houses and given Royal Assent, have the force of an Act of Parliament.17
The Methodist Church in the United States grants full clergy rights to women in 1956, and the Episcopal Church authorizes women priests and bishops in 1976. The Church of England ordains 32 women priests at Bristol on 12 March 1994, and Libby Lane is consecrated its first woman bishop on 26 January 2015.50515253
John Paul II promulgates the present Code of Canon Law by Sacrae disciplinae leges, replacing the 1917 Code; he calls it "a great effort to translate" the Council's ecclesiology into canonical language.54
The Code of Canons of the Eastern Churches is promulgated by Sacri Canones, binding all Eastern Catholic Churches from 1 October 1991.2
The Holy Synod of the Ecumenical Patriarchate decides on 11 October 2018 to proceed to grant autocephaly to the church in Ukraine, and the Russian Orthodox Church declares on 15 October 2018 that it cannot remain in Eucharistic communion with the Patriarchate of Constantinople. Patriarch Bartholomew signs the Tomos on 5 January 2019.551056
Pascite gregem Dei (23 May 2021) promulgates a revised Book VI on penal law, in force from 8 December 2021, after a revision ordered by Benedict XVI in 2007.57
Praedicate Evangelium reorganizes the Roman Curia into sixteen dicasteries and states that any member of the faithful can preside over a dicastery or office, depending on its competence.58
The United Methodist General Conference removes the Book of Discipline's prohibitions on same-sex weddings and on the ordination of self-avowed practicing homosexual clergy, and adopts regionalization. The Catholic Synod on synodality approves its Final Document on 26 October 2024, which Pope Francis calls "not strictly normative".596061
Start from the primary texts: the codes, constitutions, books of order, manuals, and court and commission reports.
Read the shared biblical texts, Acts, Titus, 1 Timothy and Matthew 18, beside each tradition's reading of them, since the texts themselves do not settle the question62636465.
Name the body that speaks for a church and the document it adopted, with its date and its section or canon, such as canon 1024 of the Code of Canon Law or Article VI of the Baptist Faith and Message as amended in 2023530.
State whether the text binds: a Lambeth resolution has no legislative force, the 2024 synod document is "not strictly normative" and Baptist confessions have "no authority over the conscience"196131.
Name the church, not the family: the Presbyterian Church in America opens the offices of elder and deacon to men only, while the Presbyterian Church (U.S.A.) holds otherwise2523.
Where a church is divided over who speaks for it, as with Gafcon and Canterbury or the Ukrainian Orthodox churches, name both claimants and the dates without choosing209.
Read church law beside the law of the state, which bears on establishment, tax status and safeguarding176667.
Check for later amendments, since several churches changed their law in 2021 to 2026.

Every tradition has law, though not all call it canon law. Catholic, Orthodox, Oriental and Anglican churches keep canons, while Protestant churches govern by church orders, constitutions, books of order, disciplines and manuals77. Most Reformation churches rejected Roman canon law, but the Church of England kept the idea of canon law and built its own, now received across the Anglican Communion77.
Most traditions name a body and texts that speak for them, such as the Pope and the college of bishops in the Catholic Church or the General Conference in session for Seventh-day Adventists337. Some have no single binding voice: Baptist confessions bind no conscience, and the provinces of the Anglican Communion are autonomous3118.
Catholic law reserves ordination to baptized men, and attempting to ordain a woman carries automatic excommunication reserved to the Holy See585. The Catholic and Orthodox churches do not ordain women as priests, while many Anglican, Lutheran, Reformed, Methodist and Pentecostal churches do. The Southern Baptist Convention limits the office of pastor to men, and the Presbyterian Church in America opens the offices of elder and deacon to men only3025.
Every church lives under its own law and the law of the state, and the relation ranges from establishment to separation. The Church of England's Measures have the force of an Act of Parliament once given Royal Assent17; in Germany, churches that are public-law corporations may levy church tax86; and section 15 of South Africa's Constitution protects freedom of religion75.
Many churches have written safeguarding into their law or binding protocols, driven by inquiries: John Jay (2004), IICSA (2020), Guidepost (2022) and the Makin Review (2024)76878889. Vos estis lux mundi requires Catholic clerics and religious to report abuse promptly and applies without prejudice to state law67, and the revised canon 1398 of 2021 punishes a cleric's sexual offenses against a minor, including grooming85.
