OrdinationOrdination is the process by which individuals are consecrated, that is, set apart and elevated from the laity class to the clergy, who are thus then authorized (usually by the denominational hierarchy composed of other clergy) to perform various religious rites and ceremonies. The process and ceremonies of ordination vary by religion and denomination. One who is in preparation for, or who is undergoing the process of ordination is sometimes called an ordinand. The liturgy used at an ordination is sometimes referred to as an ordination.
Plymouth BrethrenThe Plymouth Brethren or Assemblies of Brethren are a low church and non-conformist Christian movement whose history can be traced back to Dublin, Ireland, in the mid to late 1820s, where it originated from Anglicanism. The group emphasizes sola scriptura, the belief that the Bible is the only authority for church doctrine and practice. Plymouth Brethren generally see themselves as a network of like-minded free churches, not as a Christian denomination.
Sunday school] A Sunday school is an educational institution, usually (but not always) Christian in character. Other religions including Buddhism, Islam, and Judaism have also organised Sunday schools in their temples and mosques, particularly in the West. Sunday school classes usually precede a Sunday church service and are used to provide catechesis to Christians, especially children and teenagers, and sometimes adults as well. Churches of many Christian denominations have classrooms attached to the church used for this purpose.
Holy ordersIn certain Christian denominations, holy orders are the ordained ministries of bishop, priest (presbyter), and deacon, and the sacrament or rite by which candidates are ordained to those orders. Churches recognizing these orders include the Catholic Church, the Eastern Orthodox (ιερωσύνη [hierōsynē], ιεράτευμα [hierateuma], Священство [Svyashchenstvo]), Oriental Orthodox, Anglican, Assyrian, Old Catholic, Independent Catholic and some Lutheran churches.
Priesthood of all believersThe priesthood of all believers or universal priesthood is a biblical principle in Protestant branches of Christianity which is distinct from the institution of the ministerial priesthood (holy orders) found in some other branches, including the Roman Catholic and Eastern Orthodox. Derived from the Bible and elaborated in the theology of Martin Luther and John Calvin, the principle became prominent as a tenet of Protestant Christian doctrine, though the exact meaning of the belief and its implications vary widely among denominations.
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.
