DeaconA deacon is a member of the diaconate, an office in Christian churches that is generally associated with service of some kind, but which varies among theological and denominational traditions. Major Christian churches, such as the Catholic Church, the Oriental Orthodox Churches, the Eastern Orthodox Church, the Scandinavian Lutheran Churches, the Methodist Churches, the Anglican Communion, and the Free Church of England, view the diaconate as an order of ministry.
Infant baptismInfant baptism (or paedobaptism) is the practice of baptising infants or young children. Infant baptism is also called christening by some faith traditions. Most Christians belong to denominations that practice infant baptism. Branches of Christianity that practice infant baptism include Catholicism, Eastern Orthodoxy, and Oriental Orthodoxy. Among Protestants, several denominations practice infant baptism including Anglicans, Lutherans, Presbyterians, Congregationalists, Methodists, Nazarenes, Moravians, and United Protestants.
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.
Four Marks of the ChurchThe Four Marks of the Church, also known as the Attributes of the Church, describes four distinctive adjectives of traditional Christian ecclesiology as expressed in the Niceno-Constantinopolitan Creed completed at the First Council of Constantinople in AD 381: "[We believe] in one, holy, catholic, and apostolic Church.
DonatismDonatism was a Christian sect leading to a schism in the Church, in the region of the Church of Carthage, from the fourth to the sixth centuries. Donatists argued that Christian clergy must be faultless for their ministry to be effective and their prayers and sacraments to be valid. Donatism had its roots in the long-established Christian community of the Roman province Africa Proconsularis (present-day Tunisia, the northeast of Algeria, and the western coast of Libya) and Mauretania Tingitana (roughly with the northern part of present-day Morocco), in the persecutions of Christians under Diocletian.
ExcommunicationExcommunication is an institutional act of religious censure used to deprive, suspend, or limit membership in a religious community or to restrict certain rights within it, in particular those of being in communion with other members of the congregation, and of receiving the sacraments. It is practiced by all of the ancient churches (such as the Catholic Church, Oriental Orthodox churches and the Eastern Orthodox churches) as well as by other Christian denominations, but it is also used more generally to refer to similar types of institutional religious exclusionary practices and shunning among other religious groups.
Church of ScotlandThe Church of Scotland (The Kirk o Scotland; Eaglais na h-Alba) is the national church in Scotland. The Church of Scotland was principally shaped by John Knox, in the Reformation of 1560, when it split from the Catholic Church and established itself as a church in the reformed tradition. The church is Calvinist Presbyterian, having no head of faith or leadership group and believing that God invited the church's adherents to worship Jesus. The annual meeting of its general assembly is chaired by the Moderator of the General Assembly of the Church of Scotland.
Covenant theologyCovenant theology (also known as covenantalism, federal theology, or federalism) is a conceptual overview and interpretive framework for understanding the overall structure of the Bible. It uses the theological concept of a covenant as an organizing principle for Christian theology. The standard form of covenant theology views the history of God's dealings with mankind, from Creation to Fall to Redemption to Consummation, under the framework of three overarching theological covenants: those of redemption, of works, and of grace.
