Catholic ChurchThe Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization. The church consists of 24 sui iuris churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world.
Episcopal polityAn episcopal polity is a hierarchical form of church governance ("ecclesiastical polity") in which the chief local authorities are called bishops. (The word "bishop" derives, via the British Latin and Vulgar Latin term *ebiscopus/*biscopus, from the Ancient Greek ἐπίσκοπος epískopos meaning "overseer".) It is the structure used by many of the major Christian Churches and denominations, such as the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East, Anglican, Lutheran and Methodist churches or denominations, and other churches founded independently from these lineages.
LutheranismLutheranism is a major branch of Protestantism, identifying primarily with the theology of Martin Luther, the 16th-century German monk and reformer whose efforts to reform the theology and practices of the Catholic Church launched the Protestant Reformation. The split between the Lutherans and the Roman Catholics was made public and clear with the 1521 Edict of Worms.
ParishA parish is a territorial entity in many Christian denominations, constituting a division within a diocese. A parish is under the pastoral care and clerical jurisdiction of a priest, often termed a parish priest, who might be assisted by one or more curates, and who operates from a parish church. Historically, a parish often covered the same geographical area as a manor. Its association with the parish church remains paramount.
SynodA synod (ˈsɪnəd) is a council of a Christian denomination, usually convened to decide an issue of doctrine, administration or application. The word synod comes from the σύνοδος ˈsinoðos, meaning "assembly" or "meeting"; the term is analogous with the Latin word concilium meaning "council". Originally, synods were meetings of bishops, and the word is still used in that sense in Catholicism, Oriental Orthodoxy and Eastern Orthodoxy. In modern usage, the word often refers to the governing body of a particular church, whether its members are meeting or not.
Congregationalist polityCongregationalist polity, or congregational polity, often known as congregationalism, is a system of ecclesiastical polity in which every local church (congregation) is independent, ecclesiastically sovereign, or "autonomous". Its first articulation in writing is the Cambridge Platform of 1648 in New England. Major Protestant Christian traditions that employ congregationalism include Quakerism, the Baptist churches, the Congregational Methodist Church, and Congregational churches known by the Congregationalist name and having descended from the Independent Reformed wing of the Anglo-American Puritan movement of the 17th century.
First Council of NicaeaThe First Council of Nicaea (naɪˈsi:ə ; Sýnodos tês Nīkaíās) was a council of Christian bishops convened in the Bithynian city of Nicaea (now İznik, Turkey) by the Roman Emperor Constantine I in AD 325. This ecumenical council was the first effort to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations.
Eastern OrthodoxyEastern Orthodoxy, otherwise known as Eastern Orthodox Christianity or Byzantine Christianity, is one of the three main branches of Chalcedonian Christianity, alongside Roman Catholicism and Protestantism. Like the Pentarchy of the first millennium, the mainstream (or "canonical") Eastern Orthodox Church is organised into autocephalous churches independent from each other. In the 21st century, the number of mainstream autocephalous churches is seventeen; there also exist autocephalous churches unrecognized by those mainstream ones.
BishopA bishop is an ordained member of the clergy who is entrusted with a position of authority and oversight in a religious institution. In Christianity, bishops are normally responsible for the governance of dioceses. The role or office of bishop is called episcopacy. Organizationally, several Christian denominations utilize ecclesiastical structures that call for the position of bishops, while other denominations have dispensed with this office, seeing it as a symbol of power. Bishops have also exercised political authority.
LaityIn religious organizations, the laity (ˈleɪəti) consists of all members who are not part of the clergy, usually including any non-ordained members of religious orders, e.g. a nun or a lay brother. In both religious and wider secular usage, a layperson (also layman or laywoman) is a person who is not qualified in a given profession or does not have specific knowledge of a certain subject. The phrase "layman's terms" is used to refer to plain language that is understandable to the everyday person, as opposed to specialised terminology understood only by a professional.
